Self-reported Data (self-reported + data)
Selected AbstractsSelf-reported data in institutional research: Review and recommendationsNEW DIRECTIONS FOR INSTITUTIONAL RESEARCH, Issue 127 2005Robert M. Gonyea Higher education scholars and institutional researchers rely heavily on self-reported survey data in their work. This chapter explores problems associated with self-reports and provides questions and recommendations for their use. [source] Characterizing blood pressure control in individuals with Type 2 diabetes: the relationship between clinic and self-monitored blood pressureDIABETIC MEDICINE, Issue 9 2003R. S. Mazze Abstract Aims To determine the relationship between blood pressure (BP) measurement in the clinic and self-monitored blood pressure (SMBP); and to evaluate the accuracy of self-reported data in patients with Type 2 diabetes treated intensively for hypertension. Methods Seventy subjects had baseline and 1-week follow-up clinic BP measured using an Omron 907® automated device. During a contemporaneous 14-day period these subjects measured their BP at least four times each day using an Omron IC® semiautomatic portable monitor which, unknown to them, contained an onboard memory capable of storing BP with corresponding time and date. Results There was no significant difference between mean clinic and mean self-monitored BP. Correlations between clinic BP and SMBP were r = 0.61 (P < 0.0001) for systolic BP and r = 0.69 (P < 0.0001) for diastolic BP. Clinic BP classified 56 subjects as uncontrolled hypertension (BP , 130/80 mmHg, adjusted for diabetes) and 14 subjects as controlled hypertension. Using World Health Organization-International Society of Hypertension criteria for SMBP (, 125/75 mmHg), 55 cases of clinic classified uncontrolled hypertension were confirmed, resulting in 98% sensitivity. Clinic and SMBP agreed in one case of controlled hypertension, resulting in 7% specificity. For all subjects, the median percent of values exceeding SMBP criteria for controlled hypertension was systolic 92% and diastolic 70%. Self-reporting precision averaged 89 ± 10% (range 45,100%); under-reporting was 25 ± 16% (ranging from 0 to 56%) and over-reporting was 12 ± 15% (ranging from 0 to 46%). The overall logbook mean was not significantly different from the downloaded data from the Omron IC® monitors. Conclusions SMBP was able to identify 13 patients with uncontrolled hypertension who, by clinic BP measurement, had been classified as controlled. [source] How much alcohol do you buy?ADDICTION, Issue 4 2010A comparison of self-reported alcohol purchases with actual sales ABSTRACT Background Unrecorded alcohol has increased in the Nordic countries during recent years, above all in terms of cross-border trade. This implies that trends and levels of per capita consumption would look different without estimates of this source of alcohol, estimates that in Sweden and other countries are made through surveys. Aim The overall aim is to analyse the validity of Swedish survey estimates of alcohol bought in the cross-border trade and possibly to develop weights that can be applied to such estimates. Data and method The analysis consists of comparing self-reported purchases of spirits, wine, cider/alcopops and beer at retail monopoly (Systembolaget) during 2008 (n = 18 000) with actual sales during the same period overall and monthly. Findings Of the recorded amount of purchases at Systembolaget, 87% was reported in the survey, compared with the 40,60% usually found for self-reported consumption. Significant differences across beverages were revealed, showing a lower coverage rate for beer and spirits and a higher coverage rate for wine and cider. Changes in purchases of all beverages were captured fairly well, at least changes taking place from one month to another. Conclusions Self-reported alcohol purchases achieve a higher coverage rate than found typically in studies based on self-reported use of alcohol. If adjustments are to be made to correct for underreporting in self-reported data on alcohol purchases, different weights should be applied to different beverages. Furthermore, at least major changes in how much alcohol is purchased in the population can be monitored using well-designed population surveys. [source] Self-reported use of mental health services versus administrative records: should we care?INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2002Dr Anne E. Rhodes Abstract Studies of mental health services have emphasized that people in need are not receiving treatment. However, these studies, based on self-reported use, may not be consistent with administrative records. This study compared self-reports of mental health service use with administrative records in a large representative sample. Respondent reports within the Ontario portion of the 1994/95 Household Component of the National Population Health Survey (NPHS) were individually linked to the provincial mental-health physician reimbursement claims. A total of 5,187 Ontarians, aged 12 years or more, reported on their use of mental healthcare within the NPHS and 4,621 (89%) consented and were successfully linked to administrative records. Comparisons between the two sources identified that the agreement for any use and volume of use was moderate to low and varied according to select respondent characteristics. These differences affected estimates of the associations with use and volume of use. People who reported high levels of distress reported more visits than those who did not and this effect was stronger in the self-reported data. These results suggest that recall bias may be present. Regardless of the definition of care, access for those in need remains a concern despite universal medical insurance coverage. Copyright © 2002 Whurr Publishers Ltd. [source] Students' Drinker Prototypes and Alcohol Use in a Naturalistic SettingALCOHOLISM, Issue 1 2010Renske Spijkerman Background:, Perceptions about the type of people who drink, also referred to as drinker prototypes, may strengthen young people's motivation to engage in alcohol use. Previous research has shown that drinker prototypes are related to alcohol consumption in both adolescents and young adults. However, the evidence for the strength of these relationships remains inconclusive. One of the caveats in former studies is that all insights about prototype relations are based on self-reported data from youngsters themselves, mostly gathered in a class situation, which may contain bias due to memory distortions and self-presentation concerns. Methods:, The present study examined the impact of drinker prototypes on young adults' drinking patterns by using a less obtrusive measure to assess alcohol consumption, i.e. ad lib drinking among friend groups in the naturalistic setting of a bar lab. Drinker prototypes, self-reported alcohol use in the past, and observed alcohol intake in the bar lab were assessed among 200 college students. Relations between participants' drinker prototypes and their self-reported and observed drinking behavior were examined by computing correlations and conducting multilevel analyses. Results:, Drinker prototypes were related to both self-reported and observed alcohol use. However, the drinking patterns of friend group members had a strong impact on participants' individual drinking rates in the bar lab. After these group effects had been controlled for, only heavy drinker prototypes showed relations with observed alcohol intake in the bar lab. Conclusions:, These findings further establish the value of drinker prototypes in predicting young adults' drinking behavior and suggest that people's motivation to drink alcohol in real-life drinking situations is related to their perceptions about heavy drinkers. [source] Safety knowledge, safety behaviors, depression, and injuries in Colorado farm residentsAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 1 2010Cheryl L. Beseler PhD Abstract Background Changing safety behavior has been the target of injury prevention in the farming community for years but significant reductions in the number of farming injuries have not always followed. This study describes the relationships between safety knowledge, safety behavior, depression, and injuries using 3 years of self-reported data from a cohort of farm residents in Colorado. Methods Farm operators and their spouses (n,=,652) were recruited in 1993 from a farm truck registration list using stratified probability sampling. Respondents answered ten safety knowledge and ten safety behavior questions. The Center for Epidemiologic Studies-Depression (CES-D) scale was used to evaluate depression. The most severe farm work-related injury over a 3-year period was the outcome variable. Factor analysis was used to produce a single measure of safety knowledge for logistic regression models to evaluate the relationships between injuries, safety knowledge, and behaviors. Results Safety knowledge was significantly associated with wearing personal protective equipment. None of the safety behaviors were significantly associated with injuries. In the presence of depression, low safety knowledge increased the probability of injury (OR 3.87, 95% CI 1.00,15.0) in models adjusted for age, sex, hours worked per week, and financial problems. Compared to those not depressed, those depressed with a low safety score showed significantly greater risk of injury than those depressed with a high score in adjusted models (OR 3.09, CI 1.31,7.29 vs. OR 0.86, CI 0.31,2.37). Conclusions Future work on injuries in the farming community should include measures of mood disorders and interactions with safety perceptions and knowledge. Am. J. Ind.

Smith MPH Abstract Background Shoulder injuries are a common cause of pain and discomfort. Many work-related factors have been associated with the onset of shoulder symptoms. The psychosocial concepts in the demand,control model have been studied in association with musculoskeletal symptoms but with heterogeneous findings. The purpose of this study was to assess the relationship between the psychosocial concepts of the demand,control model and the incidence of shoulder symptoms in a working population. Methods After following 424 subjects for approximately 1 year, 85 incident cases were identified from self-reported data. Cox proportional hazards modeling was used to assess the associations between shoulder symptoms and demand,control model quadrants. Results Cases were more likely to be female and report other upper extremity symptoms at baseline (P,<,0.05). From the hazard models, being in either a passive or high strain job quadrant was associated with the incidence of shoulder symptoms. Hazard ratios were 2.17, 95% CI 1.02,4.66 and 2.19, 95% CI 1.08,4.42, respectively. Conclusions Using self-reporting to determine demand,control quadrants was successful in identifying subjects at risk of developing work-related shoulder symptoms. Research is needed to determine if this relationship holds with clinically diagnosed shoulder and other upper extremity musculoskeletal disorders. This may be part of a simple tool for assessing risk of developing these UEMSDs. Am. J. Ind. Med. 52:57,68, 2009. © 2008 Wiley-Liss, Inc. [source] Spousal concordance and reliability of the ,Prudence Score' as a summary of diet and lifestyleAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 4 2009Sanjoti Parekh Abstract Objectives: This paper describes a composite ,Prudence Score' summarising self-reported behavioural risk factors for non-communicable diseases. If proved robust, the ,Prudence score' might be used widely to encourage large numbers of individuals to adopt and maintain simple, healthy changes in their lifestyle. Methods: We calculated the ,Prudence Score' based on responses collected in late 2006 to a postal questionnaire sent to 225 adult patients aged 25 to 75 years identified from the records of two general medical practices in Brisbane, Australia. Participants completed the behavioural, dietary and lifestyle items in relation to their spouse as well as themselves. The spouse or partner of each addressee completed their own copy of the study questionnaire. Results: Kappa scores for spousal concordance with probands' reports (n = 45 pairs) on diet-related items varied between 0.35 (for vegetable intake) to 0.77 (for usual type of milk consumed). Spousal concordance values for other behaviours were 0.67 (physical activity), 0.82 (alcohol intake) and 1.0 (smoking habits). Kappa scores for test-retest reliability (n = 53) varied between 0.47 (vegetable intake) and 0.98 (smoking habits). Conclusion: The veracity of self-reported data is a challenge for studies of behavioural change. Our results indicate moderate to substantial agreement from life partners regarding individuals' self-reports for most of the behavioural risk items included in the ,Prudence Score'. This increases confidence that key aspects of diet and lifestyle can be assessed by self-report. Implications: The ,Prudence Score' potentially has wide application as a simple and robust tool for health promotion programs. [source] Genetic and environmental effects on the continuity of ejaculatory dysfunctionBJU INTERNATIONAL, Issue 12 2010Patrick Jern Study Type , Symptom prevalence (retrospective cohort) Level of Evidence 2b OBJECTIVES To investigate temporal continuity in ejaculatory dysfunction by comparing self-reported experiences of premature ejaculation (PE) at first intercourse with self-reported PE and delayed ejaculation at present, and to clarify whether and to what extent genetic or environmental factors affect continuity in ejaculatory dysfunction, as previous studies indicate moderate heritability for PE at first intercourse. SUBJECTS AND METHODS The study comprised retrospective self-reported data on ejaculatory performance at first sexual intercourse and a concurrent self-report of the same at the time of data collection in a population-based sample of 2633 Finnish twins and their siblings aged 18,48 years (mean 26.63, sd 4.68). The continuity of ejaculatory function was assessed by correlation and multiple regression. Reasons for continuity were separated into genetic and environmental sources using twin-model fitting. RESULTS Ejaculatory function, particularly PE, was stable over time. Genetic effects accounted for ,30% of the variance in PE both at first intercourse and when measured at data collection. Unshared environmental effects accounted for most of the variance (,70%). Genetic effects were almost identical between the sample occasions, but there was a substantial discrepancy between unshared environmental effects affecting PE at first intercourse and unshared environmental effects affecting PE later in life. Age effects were generally negligible. Data were self-reported and retrospective, and thus vulnerable to response bias. CONCLUSIONS Ejaculatory dysfunction seems to be temporally stable both in the short and long term. Genes that contribute to the variance in PE at first intercourse are similar to those that contribute to the variance in PE later in life, whereas there are, in this regard, substantial differences in the unshared environmental factors that are a cause of PE. [source] Validity of BMI based on self-reported weight and height in adolescentsACTA PAEDIATRICA, Issue 1 2010H Fonseca Abstract Aim:, To assess in a subset of a nationally representative sample of Portuguese adolescents, the validity of Body Mass Index (BMI) based on self-reported weight and height. Methods:, This study included 462 students in grades 6, 8 and 10 (mean age 14.0 ± 1.9 years) from 12 public schools randomly selected from the list of schools which took part in the 2006 Health Behaviour in School Aged Children Portuguese survey, corresponding to approximately 10% of the sample. Self-reported weight and height were recorded and then measured. Results:, Prevalence of normal weight, overweight and obesity based on self-report compared with that of measured values was not significantly different for boys and girls, and among age groups. BMI based on measured weight and height was underestimated compared with BMI based on self-reported data, both among girls and boys. Larger limits of agreement were found for boys, indicating a higher variability of self-reported BMI in estimating measured BMI, specifically below the age of 14 years. Conclusion:, These data suggest that BMI based on self-reported weight and height is not accurate for BMI prediction at an individual level. However, self-reported BMI may be used as a simple and valid tool for BMI estimates of overweight and obesity in epidemiological studies. [source] Significance of patient self-monitoring for long-term outcomes after lung transplantationCLINICAL TRANSPLANTATION, Issue 5 2010Christiane Kugler Kugler C, Gottlieb J, Dierich M, Haverich A, Strueber M, Welte T, Simon A. Significance of patient self-monitoring for long-term outcomes after lung transplantation. Clin Transplant 2009 DOI: 10.1111/j.1399-0012.2009.01197.x © 2009 John Wiley & Sons A/S. Abstract:, Background:, Lung transplant (LTx) recipients' adherence to regular self-monitoring of lung function (SMLF) is important in maintaining health. This study investigated patients' behavior based on electronic monitoring (EM) and compared these findings with self-reported data. Methods:, This single-center study included 269 patients following LTx. Patients reported on adherence regarding SMLF, and data were compared to electronically stored measurements for the last three months prior to self-reporting. Results:, Non-adherence was 59.4% based on EM for a total of 22 052 measurements performed. Main reported reasons for non-adherence were forgetfulness (22%), lack of time (19%), and good self-perception of health status (19%). Determinants for non-adherence were patients constraining beliefs (p , 0.0001), low perceived support from the transplant center (p , 0.008), a history of infections (p , 0.014) and rejections (p , 0.043), and bronchiolitis obliterans (p , 0.006). Multiple logistic regression revealed low-perceived support from the transplant center (OR 3.22; 95% CI 1.32,7.83; p < 0.01), and lack of support from patient organizations (OR 2.19; 95% CI 1.02,4.72; p < 0.04) as independent predictors for non-adherence. Conclusions:, LTx recipients had some difficulties maintaining SMLF on a daily basis. Non-adherence regarding lung function monitoring may provide a clinically relevant estimate of suspect cases for critical events impacting outcomes after LTx. [source] | ||||||||||
