General Population Sample (general + population_sample)
Selected AbstractsThe prognosis and incidence of social phobia in an elderly population.ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2010A 5-year follow-up Karlsson B, Sigström R, Waern M, Östling S, Gustafson D, Skoog I. The prognosis and incidence of social phobia in an elderly population. A 5-year follow-up. Objective:, To examine the prognosis and incidence of social fears and phobia in an elderly population sample followed for 5 years. Method:, A general population sample (N = 612) of non-demented men (baseline age 70) and women (baseline age 70 and 78,86) was investigated in 2000,2001 and in 2005,2006 with semi-structured psychiatric examinations including the Comprehensive Psychopathological Rating Scale, and the Mini International Neuropsychiatric Interview. Social phobia was diagnosed according to the DSM-IV criteria. Results:, Among nine individuals with DSM-IV social phobia in 2000, 5 (55.6%) had no social fears in 2005, and 1 (11.1%) still met the criteria for DSM-IV social phobia. Among individuals without DSM-IV social phobia in 2000 (N = 603), 12 (2.0%) had DSM-IV social phobia in 2005. Conclusion:, These findings challenge the notion that social phobia is a chronic disorder with rare occurrence in old age. [source] Child to adult continuities of psychopathology: a 24-year follow-upACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2009J. Reef Objective:, To determine continuities of mental health problems of children across a 24-year follow-up period. Method:, In 1983, parent ratings of emotional and behavioral problems were collected with the Child Behavior Checklist (CBCL) in a general population sample of 2076 children. Twenty-four years later, 1365 participants completed Adult Self-Reports (ASR) to assess emotional and behavioral problems. Results:, Of the participants who were classified as deviant in childhood, 22.2% were also classified as deviant in adulthood. Both homotypic and heterotypic continuity was found. Childhood aggressive, delinquent, and anxious/depressed problems were associated with most adult psychopathology. Attention problems did not predict later problems independently. Conclusion:, Even though assessed with parent-reports in childhood and analogous self-reports in adulthood, and over a large period of 24 years, continuity of psychopathology was found from childhood into adulthood. Anxious/depressed problems, delinquent behavior and aggressive behavior in childhood are core predictors for adult psychopathology. [source] Multiple adverse outcomes over 30 years following adolescent substance misuse treatmentACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009S. Hodgins Objective:, To compare outcomes over 30 years experienced by individuals who as adolescents entered substance misuse treatment and a general population sample. Method:, All 1992 individuals seen at the only clinic for substance misusing adolescents in Stockholm from 1968 to 1971 were compared to 1992 individuals randomly selected from the Swedish population, matched for sex, age and birthplace. Death, hospitalization for physical illness related to substance misuse, hospitalization for mental illness, substance misuse, criminal convictions and poverty were documented from national registers. Results:, Relative risks of death, physical illness, mental illness, substance misuse, criminal convictions and poverty were significantly elevated in the clinic compared to the general population sample. After adjustment for substance misuse in adulthood, the risks of death, physical and mental illness, criminality and poverty remained elevated. Conclusion:, Adolescents who consult for substance misuse problems are at high risk for multiple adverse outcomes over the subsequent 30 years. [source] Ethnicity, social disadvantage and psychotic-like experiences in a healthy population based sampleACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2009C. Morgan Objective: We sought to investigate the prevalence and social correlates of psychotic-like experiences in a general population sample of Black and White British subjects. Method: Data were collected from randomly selected community control subjects, recruited as part of the ÆSOP study, a three-centre population based study of first-episode psychosis. Results: The proportion of subjects reporting one or more psychotic-like experience was 19% (n = 72/372). These were more common in Black Caribbean (OR 2.08) and Black African subjects (OR 4.59), compared with White British. In addition, a number of indicators of childhood and adult disadvantage were associated with psychotic-like experiences. When these variables were simultaneously entered into a regression model, Black African ethnicity, concentrated adult disadvantage, and separation from parents retained a significant effect. Conclusion: The higher prevalence of psychotic-like experiences in the Black Caribbean, but not Black African, group was explained by high levels of social disadvantage over the life course. [source] Ready to drinks are associated with heavier drinking patterns among young femalesDRUG AND ALCOHOL REVIEW, Issue 4 2008TAISIA HUCKLE Abstract Aim. To report patterns of use of ready to drinks (RTDs) and to assess if RTD consumers have heavier drinking patterns. RTDs were introduced in 1995. Method. Data from a general population sample of 7201 respondents aged 14,65 years, in New Zealand in 2004, were modelled. Results. Nineteen per cent of respondents consumed RTDs. Respondents aged 14,17 and 18,24 years and females were the largest consumers of RTDs. Compared to beer, wine or spirits, being an RTD consumer predicted (1) higher typical occasion quantities for respondents aged 14,17, 18,24 and 25+ years and (2) heavier drinking for those aged 14,17 and 18,24 years. When amounts of beverages consumed were modelled, quantity of RTDs predicted higher typical occasion quantities among females of all ages. Among males beer was more predictive. Similar results were found for the heavier drinking measure. For 14,17-year-old females, RTDs consumption predicted higher annual frequency, but for the other females and males the amount of wine or beer consumed predicted higher frequency. Conclusion. RTDs were most popular among young people aged 14,17 years, and females. RTDs predicted higher typical occasion alcohol consumption and heavier drinking better than any other beverage for females aged 14,17 years. For the other age and gender groups, other beverages predicted higher quantity and frequency consumption. [source] Trajectories of resilience over 25 years of individuals who as adolescents consulted for substance misuse and a matched comparison groupADDICTION, Issue 7 2010Peter Larm ABSTRACT Aims To examine trajectories of resilience over 25 years among individuals who as adolescents received treatment for substance misuse, the clinical sample (CS) and a matched general population sample (GP). Design Comparison of the CS and GP over 25 years using Swedish national registers of health care and criminality. Setting A substance misuse clinic for adolescents in an urban area in Sweden. Measurements Resilience was defined as the absence of substance misuse, hospitalizations for physical illnesses related to substance misuse, hospitalization for mental illness and law-abiding behaviour from ages 21 to 45 years. Participants The CS included 701 individuals who as adolescents had consulted a clinic for substance misuse. The GP included 731 individuals selected randomly from the Swedish population and matched for age, sex and birthplace. Findings A total of 52.4% of the GP and 24.4% of the CS achieved resilience in all domains through 25 years. Among the CS, another one-third initially displayed moderate levels of resilience that rose to high levels over time, one-quarter displayed decreasing levels of resilience over time, while 9.3% showed little but improving resilience and 8.8% showed no resilience. Levels of resilience were associated with the severity of substance misuse and delinquency in adolescence. Conclusions Individuals who had presented substance misuse problems in adolescence were less likely to achieve resilience over the subsequent 25 years than was a matched general population sample, and among them, four distinct trajectories of resilience were identified. The severity and type of problems presented in adolescence distinguished the four trajectories. [source] The utility of online panel surveys versus computer-assisted interviews in obtaining substance-use prevalence estimates in the NetherlandsADDICTION, Issue 10 2009Renske Spijkerman ABSTRACT Aims Rather than using the traditional, costly method of personal interviews in a general population sample, substance-use prevalence rates can be derived more conveniently from data collected among members of an online access panel. To examine the utility of this method, we compared the outcomes of an online survey with those obtained with the computer-assisted personal interviews (CAPI) method. Design Data were gathered from a large sample of online panellists and in a two-stage stratified sample of the Dutch population using the CAPI method. Setting The Netherlands. Participants The online sample comprised 57 125 Dutch online panellists (15,64 years) of Survey Sampling International LLC (SSI), and the CAPI cohort 7204 respondents (15,64 years). Measurements All participants answered identical questions about their use of alcohol, cannabis, ecstasy, cocaine and performance-enhancing drugs. The CAPI respondents were asked additionally about internet access and online panel membership. Both data sets were weighted statistically according to the distribution of demographic characteristics of the general Dutch population. Findings Response rates were 35.5% (n = 20 282) for the online panel cohort and 62.7% (n = 4516) for the CAPI cohort. The data showed almost consistently lower substance-use prevalence rates for the CAPI respondents. Although the observed differences could be due to bias in both data sets, coverage and non-response bias were higher in the online panel survey. Conclusions Despite its economic advantage, the online panel survey showed stronger non-response and coverage bias than the CAPI survey, leading to less reliable estimates of substance use in the general population. [source] A taxometric study of alcohol abuse and dependence in a general population sample: evidence of dimensional latent structure and implications for DSM-VADDICTION, Issue 5 2009Tim Slade ABSTRACT Aims To explore, with the aid of taxometric analysis, whether alcohol abuse and alcohol dependence are each conceptualized most effectively as single latent dimensions or distinct latent categories. Design Data were taken from a nationally representative cross-sectional epidemiological survey of psychiatric and substance use disorders. Setting General population of Australia. Participants A subsample of all respondents who had consumed at least 12 drinks in the year prior to the survey and who had consumed at least three drinks on at least one single day (n = 4920 of a possible 10 641). Measurements DSM-IV criteria for alcohol abuse and dependence were assessed with the Composite International Diagnostic Interview, version 2.1. Two independent taxometric procedures, MAXimum EIGenvalue (MAXEIG) and mean above minus below a cut (MAMBAC), together with analysis of simulated dimensional and categorical data sets, were carried out. Findings Consistent evidence was found for a single latent dimension underlying the symptoms of alcohol dependence. Less consistent evidence of dimensionality was found for the symptoms of alcohol abuse. Conclusions These findings support the growing consensus regarding the need for continuous measures of alcohol use disorders to complement the traditional categorical representations in upcoming versions of the major psychiatric classification systems. [source] A longitudinal study of the effects of adolescent cannabis use on high school completionADDICTION, Issue 5 2003Michael T. Lynskey ABSTRACT Objective ,To examine the extent to which weekly cannabis use during mid-adolescence may increase the risk of early school-leaving. Setting ,A prospective study of a general population sample of adolescents studied from ages 15,21 years in Melbourne, Australia. Method ,Computer-assisted self-completion questionnaires and telephone interviews conducted in six waves at ages 15,18 and again at age 21 in a sample of 1601 male and female school students. Results ,Weekly cannabis use, assessed prospectively, was associated with significantly increased risk of early school-leaving. This effect remained after adjustment for a range of prospectively assessed covariates including demographic characteristics, other substance use, psychiatric morbidity and antisocial behavior. There was suggestive evidence of an interaction between weekly cannabis use and age with the effects of weekly cannabis use on early school-leaving being strongest at the youngest ages and diminishing progressively with age. Conclusions ,Early regular cannabis use (weekly use at age 15) is associated with increased risk of early school-leaving. These effects of regular cannabis use may diminish with increasing age and are likely to operate through the social context within which cannabis is used and obtained. [source] Evidence for conditional sex differences in emotional but not in sexual jealousy at the automatic level of cognitive processingEUROPEAN JOURNAL OF PERSONALITY, Issue 1 2008Lars Penke Abstract The two evolutionary psychological hypotheses that men react more jealous than women to sexual infidelity and women react more jealous than men to emotional infidelity are currently controversial because of apparently inconsistent results. We suggest that these inconsistencies can be resolved when the two hypotheses are evaluated separately and when the underlying cognitive processes are considered. We studied jealousy with forced-choice decisions and emotion ratings in a general population sample of 284 adults aged 20,30 years using six infidelity dilemmas and recordings of reaction times. The sex difference for emotional jealousy existed for decisions under cognitive constraint, was also evident in the decision speed, increased for faster decisions, and was stronger for participants with lower education. No evidence for a sex difference in sexual jealousy was found. Our results support the view of a specific female sensitivity to emotional infidelity that canalizes the development of an adaptive sex difference in emotional jealousy conditional to the sociocultural environment.

[source] Beyond resilients, undercontrollers, and overcontrollers? an extension of personality prototype researchEUROPEAN JOURNAL OF PERSONALITY, Issue 1 2006Philipp Yorck Herzberg Prototypes of personality were investigated in two studies. In study I, clusters of Big-Five-based prototypes were examined using a general population sample of 1908 German adults. Convergent evidence suggested the appropriateness of a five-cluster solution, which corresponds to previously identified temperament based prototypes. In study II, the five-cluster solution was cross-validated in a sample of 256 prisoners. Moreover, it was shown that a population-based approach (using discriminant functions derived from study I) was superior over the traditional sample-based cluster approach (using Ward followed by k -means). The authors argue that future typological research can be sufficiently grounded on a five-prototype conception rather than on a three-prototype conception, and suggest a new and flexible assignment procedure.

[source] Is trait-Emotional Intelligence simply or more than just a trait?EUROPEAN JOURNAL OF PERSONALITY, Issue 4 2004Karen van der Zee The present study examined the usefulness of trait-Emotional Intelligence (EI) among a sample of 1186 top managers who filled out questionnaires for Emotional Intelligence and the Big Five and were evaluated by a consultant on their competencies. Three higher-order factors were found to underlie the Bar-On Emotional Quotient Inventory (Bar-On, 1997): sense of accomplishment, empathy, and planfulness. Trait-EI was found to be substantially related to Extraversion, Agreeableness, Emotional Stability, and Autonomy. Nevertheless, the EI-factors predicted additional variance over and above the Big Five in competency to support. On the whole, top managers scored higher on the EI dimensions compared with a general population sample. High EI scores were particularly found among managers from enterprising occupational environments, that is environments dominated by activities that entail persuading and leading others to attain organizational goals or economic gain. Copyright © 2004 John Wiley & Sons, Ltd. [source] The police officer's terrorist dilemma: trust resilience following fatal errorsEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 6 2008Mathew P. White Suicide attacks have raised the stakes for officers deciding whether or not to shoot a suspect (,Police Officer's Terrorist Dilemma'). Despite high-profile errors we know little about how trust in the police is affected by their response to the terrorist threat. Building on a conceptualisation of lay observers as intuitive signal detection theorists, a general population sample (N,=,1153) were presented with scenarios manipulated in terms of suspect status (Armed/Unarmed), officer decision (Shoot/Not Shoot) and outcome severity (e.g. suspect armed with Bomb/Knife; police shoot suspect/suspect plus child bystander). Supporting predictions, people showed higher trust in officers who made correct decisions, reflecting good discrimination ability and who decided to shoot, reflecting an ,appropriate' response bias given the relative costs and benefits. This latter effect was moderated by (a) outcome severity, suggesting it did not simply reflect a preference for a particular type of action, and (b) preferences for a tough stance towards terrorism indexed by Right-Wing Authoritarianism (RWA). Despite loss of civilian life, failure to prevent minor terror attacks resulted in no loss of trust amongst people low in RWA, whereas among people high in RWA trust was positive when police erroneously shot an unarmed suspect. Relations to alternative definitions of trust and procedural justice research are discussed. Copyright © 2007 John Wiley & Sons, Ltd. [source] Subtle gene,environment interactions driving paranoia in daily lifeGENES, BRAIN AND BEHAVIOR, Issue 1 2009C. J. P. Simons It has been suggested that genes impact on the degree to which minor daily stressors cause variation in the intensity of subtle paranoid experiences. The objective of the present study was to test the hypothesis that catechol- O -methyltransferase (COMT) Val158Met and brain-derived neurotrophic factor (BDNF) Val66Met in part mediate genetic effects on paranoid reactivity to minor stressors. In a general population sample of 579 young adult female twins, on the one hand, appraisals of (1) event-related stress and (2) social stress and, on the other hand, feelings of paranoia in the flow of daily life were assessed using momentary assessment technology for five consecutive days. Multilevel regression analyses were used to examine moderation of daily life stress-induced paranoia by COMT Val158Met and BDNF Val66Met genotypes. Catechol- O -methyltransferase Val carriers displayed more feelings of paranoia in response to event stress compared with Met carriers. Brain-derived neurotrophic factor Met carriers showed more social-stress-induced paranoia than individuals with the Val/Val genotype. Thus, paranoia in the flow of daily life may be the result of gene,environment interactions that can be traced to different types of stress being moderated by different types of genetic variation. [source] Brief Communications: An Analysis of Migraine Triggers in a Clinic-Based PopulationHEADACHE, Issue 8 2010Diane Andress-Rothrock MS Background., Many migraineurs report attack "triggers," but relatively few published data exist regarding the relative prevalences of individual triggers, variations related to gender, duration of migraine or migraine subtype, or the existence of any regional variations in the prevalences and distributions of triggers. Objective., We sought to determine the prevalence and types of migraine triggers in our clinic population, to determine what influence gender, migraine subtype, or duration of migraine might have on the prevalences and types of triggers reported and to compare our findings with data derived from surveys we previously had conducted involving 2 clinic-based populations and 1 general population sample from other regions of the USA. Methods., We evaluated 200 consecutive new migraine patients referred to our clinic. All patients specifically were queried as to whether they had noted any of 7 specific factors to serve consistently as migraine attack triggers and additionally were surveyed as to whether they might have "other" triggers not listed on the intake questionnaire. Among the other data collected and analyzed were age, gender, age at time of migraine onset, and migraine subtype (ie, episodic vs chronic). Actively cycling females who reported menses as a trigger were questioned as to whether their menstrual migraine (MM) attacks differed from their non-menstrual migraines and, if so, how they differed. Results., One hundred and eighty-two patients (91%) reported at least 1 migraine trigger, and 165 (82.5%) reported multiple triggers. The most common trigger reported (59%) was "emotional stress," followed by "too much or little sleep" (53.5%), "odors" (46.5%), and "missing meals" (39%). Females or subjects of either gender with chronic migraine were no more likely than males or subjects with episodic migraine to report triggers or multiple triggers. Similarly, longer exposure to migraine did not correlate with a higher likelihood of reporting a trigger or multiple triggers. Fifty-three (62%) of 85 actively cycling females reported menses as a trigger, and of the 51 with menstrually related migraine, 34 (67%) reported their MM to be more severe, more refractory to symptomatic therapy or of longer duration than their non-menstrual attacks; 13 (24.5%) of the 53 women with apparent MM reported their MM to be at least occasionally manifested as status migrainosus. The prevalence and type of triggers reported by this predominantly white female population were similar to those reported by clinic-based populations in San Diego, California and Mobile, Alabama, and in a population-based sample of Hispanics in San Diego County. Conclusions., A large majority of migraineurs report migraine attack triggers, and the triggers most commonly reported include emotional stress, a disrupted sleep pattern, and various odors. These findings do not appear to vary according to geographic region or race/ethnicity. Among the triggers, MM appears inclined to provoke headache that is more severe, less amenable to treatment, or longer in duration than headaches that occur at other times during the cycle. (Headache 2010;50:1366-1370) [source] Contingent valuation in health care: does it matter how the ,good' is described?HEALTH ECONOMICS, Issue 5 2008Richard D. Smith Abstract A general population sample of 104 Australian respondents completed an interviewer-administered contingent valuation (CV) survey that asked them to value five scenarios representing the same core improvement in health status. These scenarios varied only in the degree of narrative used to describe the condition causing the health problem being valued and labeling of this health problem. Results indicate no significant difference in willingness to pay (WTP) between expressing symptoms as a brief or moderate narrative, but a significantly lower WTP value when expressed in an extensive narrative. WTP also differed significantly according to condition ,labels'. Possible implications for CV research are outlined. Copyright © 2007 John Wiley & Sons, Ltd. [source] It's not just what you do, it's the way that you do it: the effect of different payment card formats and survey administration on willingness to pay for health gainHEALTH ECONOMICS, Issue 3 2006Richard D. Smith Abstract A general population sample of 314 Australian respondents were randomly allocated to complete a contingent valuation survey administered by face-to-face or telephone (,phone-mail-phone') interview. Although the telephone interview was quicker to complete, no significant difference was found in values obtained through either method. Within each sub-sample, respondents were also randomly allocated to the three different versions of the payment card (PC) questionnaire format: values listed from high-to-low, values listed from low-to-high and values randomly shuffled. The high-to-low version resulted in significantly higher values than the other versions. Further analyses indicate that the randomly shuffled PC version may produce the most ,valid' values.

[source] Consumption of psychotropic medication in the elderly: a re-evaluation of its effect on cognitive performanceINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 10 2003Jacques Allard Abstract Background There have been few general population studies of the effects of psychotropic treatment on cognitive functioning in the elderly. Current evidence based on studies with numerous procedural shortenings supports the notion of the detrimental effect. Objectives To examine changes in a wide range of specific cognitive abilities across time in a general population sample in order to establish a relationship between psychotropic drug use and cognitive performance, and to estimate to what extent such cognitive changes may be attributable to psychotropic use or other factors, notably age and co-morbidity. Method We analysed the data from the Eugeria longitudinal study of cerebral ageing. Three hundred and seventy two subjects (263 female and 109 male) were visited at their place of residence and given a computerized cognitive examination. Depressive symptomatology and depressive episodes were defined according to ICD-9 criterias and medication use were established. Four categories of psychotropic consumers was differentiated. Using a logistic regression model, comparisons were made between consumers and non-consumers. Results A significant positive effect in chronic consumers was found on tests of secondary memory (delayed verbal recall: Odds Ratio (OR),=,1.22; 95% Confidence Intervals (CI) [1.04,1.43]; p,=,0.013) and this effect is principally attributable to antidepressants with significant effects being shown for both verbal (OR,=,1.59; 95%CI [1.18,2.14]; p,=,0.002) and visual recall (OR,=,1.51; 95%CI [1.05,2.16]; p,=,0.025). No effect is found for benzodiazepines. Conclusions Contrary to the common belief that psychotropic drug use has a detrimental effect on cognitive function of elderly people, even long term use is seen to be benign. We attest to the positive effects of antidepressant therapy on secondary memory. Copyright © 2003 John Wiley & Sons, Ltd. [source] Estimation of psycholeptic and psychoanaleptic medicine use in an adult general population sample using the Anatomical Therapeutic Chemical classificationINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 4 2008U. John Abstract Little is known about psycholeptic and psychoanaleptic medicine (PM) use in the general population. This study presents prevalence data about PM use. The sample included 4310 individuals aged 20,79 from a general population health examination in a northern German area (participation proportion: 68.8%; Study of Health in Pomerania, SHIP). Medicines taken during the past seven days were assessed from the medicine packages or self-reports and classified according to the Anatomical Therapeutic Chemical (ATC) classification developed by the World Health Organization. In total, 6.3% of the sample reported PM intake, 8.7% of the women and 4.7% of the men. During the past 12 months prior to the health examination, 49.2% of the individuals with PM use consulted a general practitioner but not a neurologist or a psychiatrist. Among the study participants with PM use, 88.8% had one or more mental disorders during lifetime according to a screening questionnaire. It is concluded that considerable proportions of individuals with current PM use exist although lower than may be expected on the basis of the number of individuals with mental disorder in the general population.

[source] Handicaps and the development of skills between childhood and early adolescence in young people with severe intellectual disabilitiesJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 12 2005O. Chadwick Abstract Background While a number of studies have examined the development of skills in children with intellectual disabilities (ID), most have been cross-sectional, most have been concerned with particular syndromes such as Down's syndrome or autism and few have attempted to identify factors associated with improvements in skills. Methods From a sample of 111 children with severe ID who had been identified from the registers of six special schools at 4,11 years of age, 82 were traced and reassessed 5 years later at the age of 11,17 years. On both occasions, information on the children's handicaps and skills was collected by interviewing their main carers using a shortened version of the Vineland Adaptive Behaviour Scales and the Disability Assessment Schedule. Results and conclusions There were small but statistically significant improvements in Vineland age-equivalent communication and daily living skills scores, but not in Vineland Socialization scores, over the 5-year period of follow-up. This pattern of improvement was observed in most aetiological subgroups. Improvement in skills was greatest in younger children, and was associated with reductions in behaviour problems and in levels of parental stress. In spite of the improvements in age-equivalent scores, Vineland standard scores showed significant declines over the same period of time, indicating that the improvements observed were smaller than would be expected in a general population sample of children of the same age. The dangers of using standard scores or quotients to quantify the level of functioning of children with severe ID are highlighted. [source] Effects of Parental Monitoring and Peer Deviance on Substance Use and DelinquencyJOURNAL OF MARRIAGE AND FAMILY, Issue 4 2006Grace M. Barnes From socialization theory, it was hypothesized that parental support and monitoring as well as peer deviance would influence individual trajectories of alcohol misuse, other substance use, and delinquency. Six waves of data were analyzed using interviews with 506 adolescents in a general population sample. Results from multilevel modeling showed that monitoring significantly predicted adolescents' initial levels (intercepts) of alcohol misuse and delinquency. Parental monitoring strongly predicted the rates of increase (slope) in all 3 problem behaviors. Peer deviance significantly predicted initial levels of all problem behaviors and the rates of increase in them. This study provides evidence that both effective parenting and avoidance of associations with delinquent peers are important factors in preventing adolescent problem behaviors. [source] Screening for Alcohol Problems in the U.S.ALCOHOLISM, Issue 11 2002Ethnicity, General Population: Comparison of the CAGE, RAPS, RAPS4-QF by Gender, Service Utilization Background The purpose of this study was to compare the performance (sensitivity and specificity) of two brief screening instruments, CAGE and the Rapid Alcohol Problems Screen 4 (RAPS4), against ICD-10 and DSM-IV criteria for alcohol dependence and abuse in a representative sample of the U.S. adult household population by gender, ethnicity, and service utilization (emergency room and primary care) in the last year. Methods Data are from the Alcohol Research Group's 2000 National Alcohol Survey (n= 7612), which is a computer-assisted telephone interview survey of the U.S. general population 18 and over in all 50 U.S. states and the District of Columbia. Results Sensitivity of the RAPS4 (0.86) was better than the CAGE (0.67) given similar specificity (0.95 vs. 0.98) and outperformed the CAGE for alcohol dependence across all gender, ethnic, and service utilization groups, except among blacks and Hispanics. The RAPS4 also performed equally well for females and males (0.88 vs. 0.85), whereas sensitivity of the CAGE was lower for females. Although sensitivity of the RAPS4 was better than the CAGE for alcohol abuse, sensitivity was low for both (0.56 and 0.36, respectively). When quantity-frequency (QF) questions (drinking five or more drinks on at least one occasion during the last year and drinking as often as once a month during the last year) were added to the RAPS4, the RAPS4-QF performed significantly better for alcohol abuse and outperformed the CAGE at a cut point of one across all gender, ethnic, and service utilization groups. The RAPS4-QF appeared to be most sensitive for alcohol abuse among both males and females reporting emergency room use (0.90). Conclusions The data suggest that the RAPS4 outperforms the CAGE in this general population sample. The addition of a QF question to the RAPS4 improves performance in relation to sensitivity for alcohol abuse, and the RAPS4 and RAPS4-QF may be the instruments of choice in brief screening for alcohol use disorders. Additional research is needed to further explore these issues. [source] A cross-national validity study of the Severity Indices of Personality Problems (SIPP-118)PERSONALITY AND MENTAL HEALTH, Issue 1 2009Espen Arnevik Objective,The objective in this study was to test the validity of a new dimensional measure of maladaptive core pathology for personality disorders (PDs), the Severity Indices of Personality Problems (SIPP-118), by comparing a Norwegian sample of 114 patients with PDs with two Dutch samples. In addition, Avoidant PD and Borderline PD were compared, and the relationship between scores on the SIPP-118 and commonly used clinical measures were investigated. Results,The results showed good psychometric properties of the SIPP-118 at the facet level. The Norwegian PD sample had scores equal to the Dutch PD sample and significantly below the general population sample. Correlation with other clinical measures was in the low to moderate range. Conclusion,The cross-national validity of the SIPP-118 was good, and the instrument seems promising as a dimensional instrument for measuring personality pathology. Further research should be undertaken to establish the structure of higher-order domains, its use as a measure of therapeutic change, and its capacity to distinguish Axis II from Axis I pathology.

Kim MD Abstract Background Two cases of bronchiolitis obliterans in flavor manufacturing workers prompted California health and labor agencies to initiate industry-wide surveillance. Methods Companies' physicians submitted cross-sectional questionnaire and spirometry data for 467 workers in 16 workplaces. We compared prevalence ratios of respiratory symptoms, diagnoses, and abnormal spirometry to a general population sample. We calculated odds ratios for risk factors for spirometric obstructive abnormality. Results Flavoring workers were 2.7 times more likely than the general population to have severe airways obstruction. Risk factors identified for 18 cases with obstruction from six companies included younger age, Hispanic ethnicity, liquid and powder production work, greater company diacetyl usage, and having a coworker with obstruction. Severity of obstruction was related to tenure. At least 12 workers had probable occupational fixed airways obstruction. Conclusions The flavoring industry risk of severe lung disease justifies lowering flavoring exposures and medical screening for secondary prevention until worker safety is demonstrated. Am. J. Ind.

[source] Low- and high-level controlled processing in executive motor control tasks in 5,6-year-old children at risk of ADHDTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 7 2003Ariane C. Kalff Background: The scant research on the characteristics of Attention-Deficit/Hyperactivity Disorder (ADHD) in kindergarten years curtails progress on early assessment of ADHD. Method: By screening a general population sample of 1317 five- to six-year-old children, four groups of children were selected. The performance of 30 children later diagnosed with ADHD was compared with 74 children later diagnosed with ,borderline ADHD' (children exhibiting all ADHD symptoms but without disruptions on two situations), 113 children later diagnosed with other psychopathology, and 126 healthy controls on computerised motor control tasks involving low- and high-level controlled processing. In addition, motor control was compared with movement speed. Results: The children at risk of ADHD were in general less accurate and more variable in their movements than the children with other psychopathology and healthy controls. Under conditions of high-level controlled processing, the children at risk of ADHD were disproportionately more inaccurate and had a more unstable performance with their preferred hand than the other children. In addition, linear effects were found, with the children at risk of ADHD having the worst performance, followed by the children with ,borderline ADHD', and then both groups of control children. No significant group differences were found in movement speed. Conclusions: The main findings are interpreted as evidence for a specific deficit in high-level controlled processing in young children at risk of ADHD, now found in a motor task, rather than a response task. Furthermore, the results support the notion that ADHD represents a dimensional trait. In addition, problems in movement control (the need to allocate attentional capacity) rather than problems in movement speed distinguish children at risk of ADHD from other children. The findings are interpreted as evidence that higher-order executive processes, such as self-control and self-regulation, are already affected early in the development of ADHD.

Karinen Problem:, To assess the association between antibodies to Chlamydia trachomatis heat shock proteins 60 and 10 (Hsp60 and Hsp10) and subfertility in a general population sample. Method of Study:, A nested case (n = 146),control (n = 278) study in a population-based birth cohort. Serum immunoglobulin (Ig)G and IgA antibodies against C. trachomatis Hsp60 and Hsp10, explanatory factors, were measured by enzyme immunoassay, using recombinant proteins as antigens. The main outcome variable was subfertility (time to pregnancy ,12 months). Results:, The prevalence and medians of serum IgA antibodies to Hsp60 and Hsp10 were significantly higher in the female partners of subfertile couple than in their fertile controls. On the contrary, among male partners of subfertile couple, especially among smokers serum antibody levels to Hsp antigens were lower than in the controls. Conclusion:, The results indicate a serological association of antibodies to chlamydial Hsp antigens with female subfertility in a population-based sample. [source] Developmental Trajectories of Sex-Typed Behavior in Boys and Girls: A Longitudinal General Population Study of Children Aged 2.5,8 YearsCHILD DEVELOPMENT, Issue 5 2008Susan Golombok The stability of sex-typed behavior from the preschool to the middle school years was examined. The Preschool Activities Inventory, a measure of within-sex variation in sex-typed behavior, was completed by the primary caregiver when the child was 2.5, 3.5, and 5 years, and a modified version, the Child Activities Inventory, was completed by the child at age 8. The investigation involved a general population sample of 2,726 boys and 2,775 girls. Sex-typed behavior increased through the preschool years, and those children who were the most sex typed at age 2.5 were still the most sex typed at age 5, with those children who showed the highest levels of sex-typed behavior during the preschool years continuing to do so at age 8. [source] Applying Andersen's behavioural model to oral health: what are the contextual factors shaping perceived oral health outcomes?COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 6 2009S. R. Baker Abstract,,, Objectives:, Andersen's revised behavioural model provides a framework for understanding the factors which influence utilization of health services and key health outcomes. To date, there have been few studies that have explicitly tested the model in relation to oral health. The aim of this study was to test the model and to examine the direct and mediated pathways between social, attitudinal and behavioural factors and perceived oral health outcomes. Methods:, The model was tested in a general population sample with data from the UK adult dental health survey (N = 3815) using the two-stage process of structural equation modelling. Results:, Structural equation modelling indicated support in line with the hypotheses within the model; enabling resources (oral health education advice, type of dental service, finding NHS treatment expensive, dental anxiety) predicted need (number of decayed or unsound teeth and perceived treatment need); enabling resources and need predicted personal health practices and use of services (frequency of toothbrushing, recent dental attendance, attendance orientation) which, in turn, predicted perceived oral health outcomes (oral health quality of life). Both enabling resources and need also predicted perceived oral health outcomes. The impact of predisposing factors (social class, qualifications, income) on need, personal health practices and use of services, and oral health outcomes was indirect; that is, mediated by intervening factors. In the final model, 26%, 37%, 49% and 21% of the variance was accounted for in enabling resources, treatment need, personal health practices and use of services and perceived oral health outcomes respectively. Conclusion:, The results provide support for Andersen's behavioural model as applied to perceived oral health. Further conceptual development of the model is discussed. [source] Cancer incidence in patients with schizophrenia and their first-degree relatives , a meta-analysisACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2008V. S. Catts Objective:, Controversy concerning cancer incidence in schizophrenia exists because of heterogeneous study findings. Method:, A meta-analysis was performed on standardized incidence ratios (SIR) of cancer in patients with schizophrenia and first-degree relatives and compared with general population samples. Results:, The pooled overall cancer incidence in patients was not significantly increased (SIR = 1.05, CI 0.95,1.15). Lung cancer incidence was slightly increased (SIR = 1.31, CI 1.01,1.71), but was reduced after adjusting for smoking prevalence. The incidence of several cancers unrelated to smoking was reduced in patients. Breast cancer rates were significantly increased in female patients. The pooled overall cancer incidence in siblings (SIR = 0.89, CI 0.84,0.94) and parents (SIR = 0.90, CI 0.88,0.93) was significantly reduced. A meta-regression detected a significant relationship between cancer risk in the general population and relative risk in patients. Conclusion:, The meta-analysis aided exploration of inconsistent study findings. There is a discrepancy between cancer risk exposure and cancer incidence in schizophrenia consistent with a protective effect. [source] PROD-screen , a screen for prodromal symptoms of psychosisINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 2 2003M. Heinimaa Abstract The aim of this study was to describe the PROD-screen, an instrument for screening prodromal symptoms indicating risk for psychotic conversion in the near future. PROD-screen consists of 29 questions assessing performance and symptoms. Clinical construct validity was tested by comparing scores from the unselected general population (GP, n = 64) with those of general psychiatric patients from a community mental health centre (CMHC, n = 107). The concordant validity of PROD-screen for prodromal symptoms of psychosis was assessed in a large epidemiologically mixed sample of research subjects (n = 132) by comparing PROD-screen scores with the prodromal diagnosis made by Structured Interview for Prodromal Symptoms as a gold standard. Using the cut-off point of 2/12 specific symptoms, PROD-screen gave correct classification of prodromal status in 77% of cases, distinguishing prodromal from non-prodromal subjects with reasonable sensitivity (80%) and specificity (75%) in the epidemiologically mixed sample. According to subsample analysis PROD-screen functions well with first-degree relatives of schizophrenic patients and probably also with general population samples, but not with psychiatric outpatients. In conclusion, PROD-screen is a useful tool for screening prodromal symptoms of psychosis and selecting subjects for more extensive research interviews. Copyright © 2003 Whurr Publishers Ltd.
