Selected AbstractsPsychometric Assessment of the Brazilian Version of the Breastfeeding Self-Efficacy ScalePUBLIC HEALTH NURSING, Issue 6 2009Mônica O. B. Oriá ABSTRACT Objectives: The purpose of this study was to translate and psychometrically assess the Breastfeeding Self-Efficacy Scale (BSES) among women living in Fortaleza, CE, Brazil, and examine the relationship between breastfeeding self-efficacy (BSE) and maternal demographic variables. Design and Sample: This methodological study is the first translation of BSES conducted in South America. The psychometric assessment of the original study was replicated. This methodological study enrolled a group (sample of judgment) of 117 pregnant women. Measures: BSES and maternal sociodemographic variables were studied. Results: The Cronbach's , coefficient for the translated BSES was .88. Significant differences in BSES scores were found among mothers with a previous satisfactory breastfeeding experience (M=145.81; SD=±6.82, p=.0001). Significant relationships were found among prenatal BSE and maternal age (r=.228; p=.01), educational level (r=.234; p=.01), and marital status (r=.183; p=.04). No relationship was found among BSE and maternal occupation, family income, or number of pregnancies. Conclusions: Altogether, our findings suggest that BSES translated into Portuguese may be a reliable and valid measure to assess maternal BSE in Brazilian culture. Minor changes may be needed to use it in other Portuguese-speaking countries, such as Portugal and Mozambique. [source] Engagement in a medium secure personality disorder service: A comparative study of psychological functioning and offending outcomesCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2010Lucy McCarthy Background,Specialist treatment programmes for personality disordered offenders suffer from high rates of non-completion. This has important consequences for service providers and individual patients. Method,Data from hospital records and the Offenders Index were compared for groups of treatment completers (n = 22) and non-completers (n = 59) discharged from a specialist treatment programme. Results,Twenty-seven per cent of patients completed treatment, 37% were expelled for rule breaking and 35% disengaged early from treatment. Psychometric assessments of anger expression and anxiety showed no differences between the groups, however, treatment completers showed lower levels of impulsivity and psychopathy than either of the non-completer groups. Rates of post-discharge offending for grave and standard list offences were 56.8 and 10.8%, respectively. Conclusions,Despite careful selection methods, a large proportion of personality-disordered patients admitted to specialist units failed to complete treatment. Psychometric assessments of anger expression, anxiety and impulsivity showed limited utility in differentiating treatment completers and non-completers. Sample size limitations in this naturalistic follow-up impacted on the interpretation of differences observed between the groups on the primary outcome measure of re-offending after discharge.

[source] A placebo controlled investigation into the effects of paroxetine and mirtazapine on measures related to car driving performanceHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2003F. Ridout Abstract Objective To assess the effects of paroxetine and mirtazapine on psychometric performance related to car driving, including an on-the-road test of BRT. Method In a 4-way, double blind randomised crossover study, 12 healthy volunteers received paroxetine 20,mg mane, mirtazapine 15,mg/30,mg nocte (comparator), mirtazapine 15,mg mane/15,mg b.i.d.(verum) and placebo over a 5 day period with a washout period of 7 days between treatments. Psychometric assessments included ,on-the-road' BRT (BRT), CFF (CFF), CRT (CRT) and subjective measures of sedation and sleep parameters. Results Paroxetine had no significant effect on BRT compared with placebo. Although subjective ratings of sleep quality and sedation were impaired, there were significant improvements in both CFF and the recognition reaction component of CRT with paroxetine. Mirtazapine 15,mg/30,mg nocte impaired laboratory performance and some subjective tests. Mirtazapine 15 mg mane/15,mg b.i.d. improved sleep, but significantly impaired all other measures. Conclusion Paroxetine 20,mg/day has no psychomotor or behavioural toxicity and has no negative impact on BRT. Further research into the chronic and sub-chronic effects of mirtazapine is needed to establish the clinical significance of these results. Copyright © 2003 John Wiley & Sons, Ltd. [source] Spectral electroencephalogram analysis in hepatic encephalopathy and liver transplantationLIVER TRANSPLANTATION, Issue 7 2002Alessia Ciancio The aim of this study is to evaluate the role of spectral electroencephalogram (EEG) analysis (SEEG) in quantitating brain dysfunction in cirrhotic patients, showing conditions of minimal hepatic encephalopathy (HE), and determining the impact of orthotopic liver transplantation (OLT) on its correction. SEEG was compared with visual EEG (VEEG) in 44 cirrhotic patients waiting for OLT and 44 healthy controls. Eighteen patients had overt HE, and 26 patients had no apparent HE. Twenty-one transplant recipients were reexamined 6 months after OLT. Computerized SEEG was performed by mean dominant frequency (MDF) and the occipital alpha-theta ratio, expressed as its logarithmic transformation (LogR). All patients underwent psychometric assessment. MDF and LogR correlated significantly with Child-Pugh score (P < .05) and the presence of HE (P < .0001). SEEG and VEEG determined minimal HE in 8 (31%) and 6 (23%) of 26 patients without overt HE, respectively. SEEG did not correlate with age, sex, cause of liver disease, portal hypertension, or psychometric test results. MDF and LogR improved in many transplant recipients. LogR was significantly lower in OLT candidates who died before OLT compared with OLT survivors. In conclusion, SEEG provides reliable quantitative information to evaluate the degree of HE and appears more sensitive than VEEG to discriminate a subclinical stage of HE. The improvement in SEEG results observed in transplant recipients confirms the reversibility of bioelectric brain dysfunction with restoration of liver functions. [source] Psychometric attributes of the SCOPA-COG Brazilian versionMOVEMENT DISORDERS, Issue 1 2008Francisco Javier Carod-Artal MD Abstract Cross-cultural adaptation and independent psychometric assessment of the Scales for Outcomes in Parkinson's disease-Cognition (SCOPA-COG), Brazilian version was performed. Parkinson's disease (PD) patients were evaluated by means of the SCOPA-Motor scale, Hoehn and Yahr staging (HY), Clinical Impression of Severity Index-PD (CISI-PD), Parkinson Psychosis Rating Scale, and Hospital Anxiety and Depression Scale. Cognition was evaluated using the Mini-Mental State Examination (MMSE), Short Portable Mental Status Questionnaire (SPMSQ), and SCOPA-COG. The following attributes were explored: acceptability, scaling assumptions, reliability, precision, and construct validity. One hundred fifty-two patients were assessed (mean age, 63.2 years; disease duration, 7.8 years; median HY stage, 3). Mean SCOPA-COG and MMSE were 18.2 and 25.7, respectively. The internal consistency of the SCOPA-COG (Cronbach's alpha = 0.81; item-total correlation, 0.38,0.62) was satisfactory. While the intraclass correlation coefficient value was 0.80, weighted kappa ranged from 0.30 (dice task) to 0.72 (animal fluency task). The standard error of measurement value for the SCOPA-COG was 3.2, whereas the smallest real difference was 8.9. SCOPA-COG total scores significantly decreased as the HY stage increased (Kruskal-Wallis, P < 0.0001). Age, years of education, and PD duration (all, P < 0.001) were observed to have an independent, significant effect on the SCOPA-COG. The SCOPA-COG is a short, reliable, valid instrument that is sensitive to cognitive deficits specific to PD. © 2007 Movement Disorder Society [source] Characterizing behavioral and cognitive dysexecutive changes in progressive supranuclear palsyMOVEMENT DISORDERS, Issue 2 2006David Millar DClinPsy Abstract Frontal lobe dysfunction is a prominent feature of many neurological disorders. Early diagnosis may be enhanced by establishing a profile of cognitive, behavioral, and emotional change. Traditional psychometric assessment focuses on cognitive dysfunction and fails to identify behavioral changes, particularly those associated with orbitofrontal dysfunction. We examined progressive supranuclear palsy (PSP), a prototypical subcortical dementia with frontal features, using commonly available neuropsychological measures and a modification of the Katz Adjustment Scale-Relatives (KAS-R), an instrument first developed to assess dysexecutive changes in head-injured patients. Executive tests identified deficits in reasoning, planning, set shifting, verbal fluency, information processing speed, and response initiation. On the KAS-R, changes in apathy, social withdrawal, and independence were observed, with little change in belligerence, social irresponsibility, uncooperativeness, obstreperousness, anxiety, and depression. The results show the potential utility of this instrument in characterizing behavioral and emotional changes associated with frontal lobe dysfunction in neurodegenerative disease. © 2005 Movement Disorder Society [source] Psychometric testing of the Perception of Pregnancy Risk Questionnaire,RESEARCH IN NURSING & HEALTH, Issue 5 2009Maureen I. Heaman Abstract Pregnant women's perception of risk may influence their health behaviors during pregnancy; however, no validated instrument exists to measure those perceptions. The purpose of this study was to refine a new instrument, the Perception of Pregnancy Risk Questionnaire (PPRQ), and conduct psychometric assessment of the final 9-item version. Reliability and validity were assessed using a sample of 199 women in the third trimester of pregnancy. Exploratory factor analysis resulted in a two-factor solution. Evidence of construct validity was demonstrated using the known-groups technique and through convergent validity. Ratings of pregnancy risk correlated with state anxiety level, providing evidence of concurrent validity. The PPRQ had high internal consistency reliability and excellent test,retest reliability. © 2009 Wiley Periodicals, Inc.

Peters Abstract The purpose of this study was to develop and conduct preliminary psychometric assessment of instruments measuring knowledge and self-care practices regarding behaviors needed for blood pressure (BP) control among African Americans. Items were empirically derived and scored on a 7-point, bipolar scale. The instruments were evaluated in a sample of 306 community-dwelling African Americans. Results revealed acceptable reliability and validity of the BP Knowledge Scale. Results for the BP Self-Care Scale were mixed. A structural equation model of these scales, recorded BP, and covariates fit well. There was an unexpected positive correlation between self-care and BP suggesting a potential bi-directional relationship. The scales demonstrated acceptable psychometric properties and, with minor revisions, may have clinical utility as measures of BP knowledge and self-care. © 2008 Wiley Periodicals, Inc. Res Nurs Health 31:543,552, 2008 [source] Estimating driver risk using alcohol biomarkers, interlock blood alcohol concentration tests and psychometric assessments: initial descriptivesADDICTION, Issue 2 2010Paul Marques ABSTRACT Aim To identify alcohol biomarker and psychometric measures that relate to drivers' blood alcohol concentration (BAC) patterns from ignition interlock devices (IIDs). Design, setting, participants, measurements In Alberta, Canada, 534 drivers, convicted of driving under the influence of alcohol (DUI), installed IIDs and agreed to participate in a research study. IID BAC tests are an established proxy for predicting future DUI convictions. Three risk groups were defined by rates of failed BAC tests. Program entry and follow-up blood samples (n = 302, 171) were used to measure phosphatidyl ethanol (PETH), carbohydrate deficient transferrin (%CDT), gamma glutamyltransferase (GGT) and other biomarkers. Program entry urine (n = 130) was analyzed for ethyl glucuronide (ETG) and ethyl sulphate (ETS). Entry hair samples were tested for fatty acid ethyl esters (FAEE) (n = 92) and ETG (n = 146). Psychometric measures included the DSM-4 Diagnostic Interview Schedule Alcohol Module, Alcohol Use Disorders Identification Test (AUDIT), the time-line follow-back (TLFB), the Drinker Inventory of Consequences (DRINC) and the Temptation and Restraint Inventory (TRI). Findings Except for FAEE, all alcohol biomarkers were related significantly to the interlock BAC test profiles; higher marker levels predicted higher rates of interlock BAC test failures. PETH, the strongest with an overall analysis of variance F ratio of 35.5, had significant correlations with all nine of the other alcohol biomarkers and with 16 of 19 psychometric variables. Urine ETG and ETS were correlated strongly with the IID BAC tests. Conclusions The findings suggest that several alcohol biomarkers and assessments could play an important role in the prediction and control of driver alcohol risk when re-licensing. [source] |
