Survey of substance use among high school students in Taipei: web-based questionnaire versus paper-and-pencil questionnaire.

PURPOSE: To evaluate, using a randomized trial, whether a web-based self-administered questionnaire (web SAQ) can improve the reporting rate of substance use in adolescents compared with a paper-and-pencil self-administered questionnaire (paper SAQ). METHODS: Students of junior high, senior high, and vocational high schools in Taipei City and County were selected by a stratified, two-stage, probability proportional to size, random sampling. For each class selected, half of the students were randomly assigned to paper SAQ (n = 990) and the other half to web SAQ (n = 928). The inverse of the sampling probability for each individual was then used as sampling weight in the estimation of prevalence and logistic regression analysis. RESULTS: For readily available substances, the lifetime prevalence in the web SAQ group was significantly higher for alcohol use and borderline higher for tobacco and betel nut use compared to those of the paper SAQ group. For illicit drug use, the lifetime prevalence for the web SAQ group was significantly higher for the use of amphetamines, and borderline higher for ketamine. In multiple logistic regression analysis, the differences between the two groups in the use of alcohol, tobacco, and amphetamines remained significant. Boys, as well as both junior-high and vocational high school students who responded using the web SAQ, were more likely to report alcohol or tobacco use than those using the paper SAQ. CONCLUSIONS: Web SAQ leads to higher reporting rates of commonly used substances in adolescents compared with those of paper SAQ.

The Adaptive Behaviour Dementia Questionnaire (ABDQ): screening questionnaire for dementia in Alzheimer's disease in adults with Down syndrome.

The diagnosis of dementia in Alzheimer's disease remains at times problematic in adults with intellectual disability. The analysis of 5-year consecutive data developed a researched-based clinical screening tool for dementia in Alzheimer's disease in adults with Down syndrome. The Adaptive Behaviour Dementia Questionnaire (ABDQ) is a 15-item questionnaire, which is used to detect change in adaptive behaviour. The scale has good reliability and validity, with an overall accuracy of 92%. It is the first clinical tool designed specifically to screen for dementia in Alzheimer's disease in adults with Down syndrome.

Relative responsiveness of the Chronic Respiratory Questionnaire, St. Georges Respiratory Questionnaire and four other health-related quality of life instruments for patients with chronic lung disease.

BACKGROUND: Selection of heath-related quality of life (HRQL) instruments that are most responsive to changes in HRQL prevents investigators from drawing false-negative conclusions about the effectiveness of an intervention. The objective of this study was to compare the responsiveness of the Chronic Respiratory Questionnaire (CRQ), the St. Georges Respiratory Questionnaire (SGRQ) and four other HRQL instruments. METHODS: We enrolled 177 patients with chronic lung disease, primarily COPD (93%), who completed 8 weeks of respiratory rehabilitation. Patients completed the CRQ, the SGRQ and four generic measures (SF-36, Feeling Thermometer, Standard Gamble and Health Utilities index 3) at the beginning of the rehabilitation program and 12 weeks thereafter. We calculated standardized response means (SRMs) for each instrument, from the change score divided by the standard deviation of the change score. RESULTS: We observed the largest SRM for the CRQ (0.24-0.66 for the four CRQ domains on the interviewer-administered and 0.56-0.84 for the self-administered format) and the SGRQ (0.33-0.51 for the three SGRQ domains and total score). The CRQ dyspnea domain was statistically significantly more responsive than any other instrument including the SGRQ. For the SGRQ, the total and impacts domain were significantly more responsive than the generic and preference-based instruments. CONCLUSIONS: This study confirms that the CRQ and SGRQ are substantially more responsive than generic measures, and suggests particularly strong responsiveness for the self-administered CRQ.

Is questionnaire enough to assess number of nocturic episodes? Prospective comparative study between data from questionnaire and frequency-volume charts.

OBJECTIVES: To determine whether the voiding symptom questionnaire provides information regarding nocturia as accurate as that provided by frequency-volume (FV) charts, we evaluated patients with lower urinary tract symptoms. METHODS: We prospectively analyzed 164 patients (62 men and 102 women, mean age 53.6 years, range 20 to 83) referred for the evaluation of lower urinary tract symptoms. At the initial visit, all patients answered the International Prostate Symptom Score (IPSS) questionnaire to quantify nocturia and subsequently were requested to complete a 3-day FV chart. RESULTS: The differences in age between the men and women were not statistically significant. The total IPSS and IPSS bother scores were similar between the sexes. For all patients, the actual number of nightly voids in the FV charts and the IPSS nocturia score were modestly intercorrelated (r = 0.609, P <0.001). However, large individual differences were found in the nighttime diuresis rate (67.7%) between the IPSSs and FV charts. No statistically significant differences were found between men and women, but agreement was achieved in only 39.2% of patients younger than 60 years old and 22.4% of those 60 years old or older for the number of voids per night recorded by the FV charts and reported by the IPSS (P = 0.024). Overestimation of the number of nocturic episodes in the IPSS was more common than underestimation, especially in patients 60 years old or older (P = 0.014). CONCLUSIONS: The findings of the present study revealed poor agreement between the subjectively estimated nocturnal frequency and chart-determined nocturnal frequency. Our results suggest that FV charts should be included as an integral part of evaluating nocturia in both sexes.

Assessing adherence to dietary recommendations for hemodialysis patients: the Renal Adherence Attitudes Questionnaire (RAAQ) and the Renal Adherence Behaviour Questionnaire (RABQ).

This article describes preliminary investigations into the psychometric properties of two scales for hemodialysis patients (N=35): the Renal Adherence Attitudes Questionnaire (RAAQ), a 26-item scale measuring attitudes toward adherence: and the Renal Adherence Behaviour Questionnaire (RABQ), a 25-item scale measuring self-reported dietary (diet and fluid) adherence. Factor analysis of the RAAQ yielded a four-factor structure. These factors were attitudes to social restrictions, well-being, self-care/support, and acceptance. The scale demonstrated high internal and test-retest reliability. Factor analysis of the RABQ gave a five-factor structure: adherence to fluid restrictions; adherence regarding potassium and phosphate restrictions, adherence regarding self-care; adherence regarding sodium intake; and adherence in times of particular difficulty. This scale had moderately high internal reliability and high test-retest reliability. Validity for the RABQ was tested with independent measures of adherence; biochemical (serum potassium, serum phosphate, and interdialytic weight gain) and dietician-rated (potassium and fluid). There was little association among the differing measures of adherence. These scales facilitate empirical evaluation of dietary adherence for hemodialysis patients.

Prevalence of seasonal affective disorder in primary care; a comparison of the seasonal health questionnaire and the seasonal pattern assessment questionnaire.

BACKGROUND: Prevalence rates of SAD suggested by previous studies have ranged from 1 to 12% depending on the diagnostic criteria used. The Seasonal Pattern Assessment Questionnaire (SPAQ), a widely used screening tool, has been shown to have low specificity for SAD. The Seasonal Health Questionnaire (SHQ) was designed to better reflect the clinical criteria for SAD and has been shown to have a higher specificity then the SPAQ in a psychiatric outpatient setting. OBJECTIVE: The current study was designed to assess the validity of the SHQ in general practice against systematic research interviews, to compare the sensitivity, specificity and positive predictive values of the SHQ and the SPAQ and to use these data to estimate the prevalence of SAD in primary care. METHODS: 809 subjects in a consecutive series of patients attending Southampton general practices in winter 2000/01 completed the SHQ followed by the SPAQ; 56 were interviewed using the Structured Clinical Interview for DSM (SCID). RESULTS: The SHQ was more sensitive and specific than the SPAQ and had higher positive and negative predictive values in screening for SAD. The SPAQ indicated a prevalence of SAD of 10.7% (95% CI 8.6-13.1) while the SHQ provided a significantly lower estimate of 5.6% (95% CI 4.2-7.4).

Initial validation of two opiate craving questionnaires the obsessive compulsive drug use scale and the desires for drug questionnaire.

In the present study, the factor structure, internal consistency, and the concurrent validity of two heroin craving questionnaires are examined. The Desires for Drug Questionnaire (DDQ) measures three factors: desire and intention, negative reinforcement, and control. The Obsessive Compulsive Drug Use Scale (OCDUS) also measures three factors: thoughts about heroin and interference, desire and control, and resistance to thoughts and intention. Subjects were 102 Dutch patients who were currently in treatment for drug dependency. All proposed scales have good reliability and concurrent validity. Implementation of these instruments in both clinical and research field is advocated.

Development of a questionnaire to evaluate the information needs of cancer patients: the EORTC questionnaire.

Information disclosure is one of the key areas of support that patients may receive. The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group has a group working on the development of a questionnaire that evaluates information received by cancer patients at different stages of their disease--EORTC QLQ-INFO30. This instrument is being developed by professionals from most European regions. The questionnaire aims to evaluate the information received by cancer patients on different areas of the disease, diagnosis, treatment and care. Besides, the instrument also assesses qualitative aspects of the information they have received. The present paper presents the first two phases of the module development process that include literature review, interviews with patients and professionals, and formulation of the items. All these steps have been carried out in different countries and have been approved by the EORTC QLG.

[Systematic use in hospitals of a alcohol problems detecting questionnaire. The CAGE (cut down, annoyed, guilty, eye opener) questionnaire].

OBJECTIVES: The CAGE questionnaire is considered a useful tool for detecting alcohol problems, especially in clinical populations. Its sensitivity exceeds 75% and its specificity 90%. Our objective was to assess performance of the French version of the CAGE (DETA) in identifying patients who meet the DSM-IV criteria and to discuss its usefulness in hospitals. METHODS: Data come from study of hospital morbidity in the Auvergne district of central France in 1998. Alcohol problems were diagnosed by physicians using the DSM-IV alcohol abuse or dependency criteria. For each diagnostic category, we calculated the performance of the CAGE questionnaire at a cut-off of 2 (CAGE 2+) and of 1 (CAGE 1+). RESULTS: The study included 5,452 patients--48.5% of them men--in acute- and intermediate-care facilities. CAGE 2+ had a sensitivity of 77% and a specificity of 94% among the diagnosed patients. It was more sensitive for patients diagnosed as alcohol-dependent than for alcohol abusers (61% vs 84%), but specificity was identical for both groups (94%). These results are similar to the properties of the English version. For a cut-off of 1 the CAGE had a sensitivity of 88% and a specificity of 87%. CONCLUSION: The French version of CAGE is a useful screening tool for alcohol abuse and dependance. Its systematic use in hospitals is desirable: a positive response to any item should attract the physician's attention and lead to further investigation.

The Reassurance Questionnaire (RQ): psychometric properties of a self-report questionnaire to assess reassurability.

BACKGROUND: The aim of this study was to develop a questionnaire that assessed the extent to which patients usually feel reassured by their attending physician. METHODS: The study population consisted of 204 subjects from the general population, 113 general practice patients, 130 general medical out-patients and 183 general medical patients with unexplained physical symptoms participating in an intervention study on the effect of cognitive behavioural therapy. RESULTS: Factor analysis yielded a one-factor solution. The internal consistency was moderate to high and the test-retest reliability was high. The convergent validity of the Reassurance Questionnaire (RQ) was satisfactory to good, but the scores on the RQ did not appear to differentiate between the general population, general practice patients and general medical out-patients. In medical out-patients with unexplained physical symptoms, the RQ discriminated well between hypochondriacal and non-hypochondriacal patients. Scores on the RQ tended to be associated with a bad outcome in terms of recovery of presenting symptoms at 1 year follow-up. There was no association between scores on the RQ and frequency of physician contact. In patients with unexplained physical symptoms treated with cognitive behavioural therapy, scores on the RQ decreased over a period of 6 months and 1 year. CONCLUSIONS: The RQ was demonstrated to have psychometrically sound properties and appeared to be a useful instrument to assess reassurability in medical patients.

Development of a shortened version of the Breathing Problems Questionnaire suitable for use in a pulmonary rehabilitation clinic: a purpose-specific, disease-specific questionnaire.

One hundred and thirty-eight chronic obstructive pulmonary disease (COPD) patients completed the Breathing Problems Questionnaire (BPQ) before and after a comprehensive programme of rehabilitation. Examination of the changes on individual items showed improvement on 22 items, of which four items were significant at p < 0.05 and deterioration on nine items, of which two were significant at p < 0.01. All deteriorating items were consistent with lifestyle adaptations encouraged as part of the rehabilitation programme. We examined the psychometric properties of a reduced ten item version of the BPQ limited to the items most sensitive to change. We recommend the purpose-specific, disease-specific COPD scale for measuring change in pulmonary rehabilitation assessment in contrast to the longer 33 item questionnaire, which, however, may be more useful for cross-sectional assessment.

The adaptations of a quality of life questionnaire for routine use in clinical practice: the Chronic Respiratory Disease Questionnaire in cystic fibrosis.

The assessment of quality of life (QoL) is necessary to monitor the course of disease and to assess the effect of new and existing interventions in clinical practice. This will only be achieved if QoL can be measured accurately and routinely. The aim of this study was to demonstrate the methodology involved in the adaptation and shortening of the Chronic Respiratory Disease Questionnaire (CRDQ) in a population of adults with cystic fibrosis (CF). A single interviewer administered the CRDQ to a sample of 45 adult patients (32 males) with CF prior to assessment of spirometric measures of lung function. Those patients whose lung function was stable at the time of study and who could attend for a retest within 14 days were asked to complete the questionnaire at a subsequent visit (n = 10). The mean interval between visits was 7 days (range 5-14 days). Correlations between spirometry and CRDQ dimensions ranged from -0.003 to 0.426. The fatigue, emotion and mastery dimensions showed high internal consistency and adequate construct validity. In the small number of patients suitable for retest, the results indicated that the dimensions exhibited adequate test-retest reliability. In contrast, low internal consistency was demonstrated for the dyspnoea dimension. The fatigue, emotion and mastery dimensions could be reduced, in terms of their number of items, without a substantial loss in explanatory power. This study suggests that QoL measurement can be made convenient and, thus, more easily accessible for routine clinical assessment.

The reliability and validity of the Perceived Stigmatization Questionnaire (PSQ) and the Social Comfort Questionnaire (SCQ) among an adult burn survivor sample.

In this study, 361 adult burn survivors completed the Perceived Stigmatization Questionnaire (PSQ), the Social Comfort Questionnaire (SCQ), and other measures. Both the PSQ and SCQ had good internal consistency indices. Factor analysis of the PSQ yielded 3 factors (absence of friendly behavior, confused/staring behavior, and hostile behavior). The SCQ had 1 factor. Conjoint factor analysis with measures of related constructs (body esteem, body-esteem importance, depression, social support) suggested that PSQ and SCQ measure distinct constructs. Correlations with the related psychosocial constructs and burn characteristics suggested the PSQ and SCQ have good convergent and discriminant validity. Limitations of the study are discussed.

Validity and utility of the PRIME-MD patient health questionnaire in assessment of 3000 obstetric-gynecologic patients: the PRIME-MD Patient Health Questionnaire Obstetrics-Gynecology Study.

OBJECTIVE: This study was undertaken to determine the prevalence of mental disorders among obstetric-gynecologic patients and to assess the validity and utility of the PRIME-MD Patient Health Questionnaire (PHQ) in this population. STUDY DESIGN: A total of 3000 patients were assessed by 63 clinicians at seven obstetrics-gynecology outpatient care sites. The main outcome measures were PRIME-MD PHQ diagnoses, psychosocial stressors, independent diagnoses made by mental health professionals, functional status measures, disability days, health care use, and treatment or referral decisions. RESULTS: Current mental disorders were fairly prevalent, present in 1 in 5 obstetric-gynecologic patients. Patients with PRIME-MD PHQ diagnoses had more functional impairment, disability days, health care use, and psychosocial stressors than did patients without PRIME-MD PHQ diagnoses (P <.005 for all measures). Although most clinicians judged the PRIME-MD PHQ to be useful in management decisions, the questionnaire diagnosis of mental disorder rarely led to therapeutic intervention. CONCLUSION: The PRIME-MD PHQ is a useful instrument for the assessment of mental disorders, functional impairment, and recent psychosocial stressors in the busy obstetrics-gynecology setting.

Validity and reliability of a work history questionnaire derived from the Job Content Questionnaire.

Job design risk factors for hypertension and heart disease have often been assessed by the Job Content Questionnaire (JCQ). Job characteristics are typically assessed only once, however, which can result in misclassification and bias results toward the null. Newer approaches, which assess job characteristics over a working life, are hampered by the need to ask numerous questions about each job, increasing survey length and potentially reducing response rates. Participants in the Work Site Blood Pressure Study, a prospective study of psychosocial factors and ambulatory blood pressure, completed the JCQ about their current jobs. At later dates, 213 employed men, a subset of the original cohort, retrospectively completed the Work History Questionnaire (WHQ), a short version of the JCQ, for each past job. The WHQ exhibited moderate validity for assessing past job characteristics, a weak association with systolic blood pressure, and expected patterns of change over time. Thus, it may be a valuable tool for measuring the health effects of historical job characteristics, which often change over time.

Comparison of the General Health Questionnaire and the Cornell Medical Index Health Questionnaire.

This study compares the 30-item version of the General Health Questionnaire (GHQ) and the psychiatric section of the Cornell Medical Index Health Questionnaire (CMI-MR) using normative data from a sample of the general population and data from general practice patients where clinical assessment by a psychiatrist is used as a criterion of psychiatric caseness. In this study the CMI-MR has a slightly better overall performance as a screening test. It appears that the CMI-MR errs in the direction of false negatives when the symptoms are recent and related to situational stress, but the GHQ has a tendency to miss cases with symptoms of long standing.

Validation of the Dutch translation of the Inflammatory Bowel Disease Questionnaire (IBDQ): a health-related quality of life questionnaire in inflammatory bowel disease.

Health-related quality of life assessment can benefit several groups involved with health care. The aim of our study was to assess construct validity, reliability, discriminant ability and sensitivity to change of the Dutch translation of the Inflammatory Bowel Disease Questionnaire (IBDQ), a disease-specific quality-of-life questionnaire. A group of 120 IBD patients completed the IBDQ and two Visual Analogue Scales concerning general well-being and bowel function twice. Fifty-two patients also completed the Short-Form 36 twice. Disease activity was assessed once. Correlations between the IBDQ scores and the global assessments were reasonably high and the IBDQ was shown to be discriminative. High intraclass correlation coefficients between both measurements of the IBDQ were observed in patients who reported no change in bowel complaints. In contrast, significant differences were found between both moments in patients who reported change. The Dutch IBDQ proved to be valid, discriminative and reliable.
