Fear-avoidance beliefs as measured by the fear-avoidance beliefs questionnaire: change in fear-avoidance beliefs questionnaire is predictive of change in self-report of disability and pain intensity for patients with acute low back pain.

OBJECTIVES: The purposes of this study were to investigate the association among measures of fear-avoidance beliefs, pain intensity, and lumbar flexion and to determine if changes in these measures were predictive of treatment outcome following physical therapy for acute low back pain. It was hypothesized that items of the Fear-Avoidance Beliefs Questionnaire would be correlated with concurrent measures of pain intensity and lumbar flexion. In addition, it was hypothesized that changes in fear-avoidance beliefs would be predictive of changes in self-report of pain intensity and disability. STUDY DESIGN: Patients underwent a standard examination that included measures of fear-avoidance beliefs, pain intensity, lumbar flexion, and disability from low back pain. Patients were then re-examined after 4 weeks of physical therapy treatment. PATIENTS: Sixty-three patients with acute low back pain enrolled in a clinical trial of physical therapy treatment. RESULTS: Fear-Avoidance Beliefs Questionnaire items were consistently correlated with lumbar flexion, but not with measures of pain intensity. Pearson correlations indicated that changes in disability were significantly associated with changes in fear-avoidance beliefs and pain intensity, but not changes in lumbar flexion. Changes in fear-avoidance beliefs explained significant amounts of variance in changes in average pain intensity while controlling for changes in lumbar flexion. Changes in fear-avoidance beliefs explained significant amounts of variance in changes in disability while controlling for changes in average pain intensity. CONCLUSIONS: These results suggest that fear-avoidance beliefs have a similar association with pain intensity, physical impairment, and disability for patients with acute and chronic low back pain. This study provides preliminary support for the use of the Fear-Avoidance Beliefs Questionnaire as an outcome measure for patients with acute low back pain.

Comparison of a video questionnaire with the IUATLD written questionnaire for measuring asthma prevalence.

A video questionnaire (VQ) for measuring asthma prevalence in adolescents was assessed for repeatability and validity in relation to bronchial hyperresponsiveness (BHR) (PD20 less than or equal to 7.8 mumol methacholine). Comparison was also made with a standard, self completed written questionnaire (SQ), based on the IUATLD Bronchial Symptoms Questionnaire, which included five questions seeking comparable data to those in the VQ. Both the VQ and SQ were administered to 707 schoolchildren (13-16 years), in whom English was the primary language. One hundred and six randomly selected children subsequently underwent bronchial challenge to methacholine. Both the sensitivity and specificity for BHR were higher for a combination of three or more positive responses to the VQ (0.73 and 0.88), than to the SQ (0.63 and 0.82), although these differences were not statistically significant (P = 0.24). When administered again after a two week interval, the VQ had a significantly higher (P = 0.03) coefficient of repeatability (0.79) than the SQ (0.50). We conclude that the VQ is a valid and reliable method of determining asthma prevalence, and propose that by providing data relatively free from biases due to language, culture, literacy or interviewing techniques it may be particularly useful when comparing asthma prevalence and severity in different populations.

The validity of the ISAAC written questionnaire and the ISAAC video questionnaire (AVQ 3.0) for predicting asthma associated with bronchial hyperreactivity in a group of 13-14 year old Korean schoolchildren.

To validate the prevalence rate of symptoms of asthma produced by the phase I ISAAC (International Study of Asthma and Allergies in Childhood) study, hypertonic saline challenge test was carried out during the phase II study at a year after the phase I study. For the phase II study, six middle schools from three cities in the phase I study were selected. Finally, 499 children who responded to both studies were analyzed. All subjects were asked to complete the written questionnaire (WQ) first, followed by a video questionnaire (AVQ 3.0) during the phase I study. Of the 499 children, only 19 (3.8%) were positive to the hypertonic saline bronchial challenge test. The degree of agreement between responses to the two corresponding questions "wheezing at rest" and "nocturnal wheeze" in the AVQ 3.0 and WQ were moderate and weak with a Kappa indices of 0.45 and 0.23, respectively. The question on "severe wheeze" in the AVQ 3.0 had the highest Youden's index among the five questions related to asthma symptoms in the previous 12 months, but its specificity was low whereas its sensitivity was 1.0. There was no consistency of priority between the two questionnaires in predicting bronchial hyperreactivity in a group of Korean schoolchildren. Therefore we need to develop more appropriate WQ or AVQ to compare the prevalences of asthma to other countries.

The reliability and validity of a screening Questionnaire for 13 DSM-IV Axis I disorders (the Psychiatric Diagnostic Screening Questionnaire) in psychiatric outpatients.

BACKGROUND: The purpose of this study was to examine the reliability and validity of a new multidimensional screening instrument for 13 DSM-IV Axis I disorders. METHOD: The Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a 90-item self-administered questionnaire that screens for 13 DSM-IV disorders in 5 areas (eating, mood, anxiety, substance use, and somatoform disorders). A consecutive series of 500 psychiatric outpatients completed the PDSQ immediately before their intake evaluation. Seventy-four patients completed the scale a second time less than a week after the initial administration, and 51 patients completed a booklet of questionnaires that included established measures of the same symptom domains assessed by the PDSQ. RESULTS: The PDSQ subscales achieved moderate-to-high levels of internal consistency (mean Cronbach's alpha coefficient = 0.82) and test-retest reliability (mean correlation coefficient = 0.84). Subscale scores were significantly associated with blind clinical diagnoses, and individual PDSQ items correlated much more highly with their own subscale than with other subscales. The PDSQ subscales were much more highly correlated with established measures of the same symptom domain (mean correlation coefficient = 0.72) than with measures of other types of psychopathology (mean correlation = 0.17). CONCLUSION: The PDSQ is a reliable and valid measure of multiple DSM-IV disorders that is brief enough to be incorporated into routine clinical outpatient practice without disruption, yet lengthy enough to be a psychometrically sound instrument.

Comparison of the Personal Health Questionnaire and the Self Reporting Questionnaire in rural Pakistan.

OBJECTIVE: To apply ROC analysis to select the best threshold scores for the PHQ and SRQ; to compare the sensitivity and specificity of the PHQ and SRQ against a criterion diagnosis of depressive disorder in a community sample in rural Pakistan, and to examine the influence of socio-demographic factors on misclassification. METHODS: The study used a two-stage design. Receiver Operating Characteristic (ROC) analysis was used to estimate the optimal threshold score and to compare the ability of the Self Reporting Questionnaire (SRQ) and the Personal Health Questionnaire (PHQ) to discriminate between cases of depressive disorder and non-cases. RESULTS: The results of the ROC analysis suggest that the SRQ is superior to the PHQ, and at the threshold of 5/6, the SRQ has superior sensitivity, negative predictive value and percentage agreement compared with the PHQ. When the SRQ threshold is raised it gains specificity, and at a cut-off threshold of 7/8 it is superior to the PHQ (5/6) in all validity coefficients and percentage agreement. Only gender and the presence of a confidant had a significant effect on misclassification using the SRQ among the cases. Both questionnaires performed better for females based on comparison of the areas under the ROC curves. CONCLUSION: This study has demonstrated that the Urdu translations of both the PHQ and SRQ can be used as screening tests for depressive disorder in the Pakistani population. People with little or no education answer both somatic and psychological items with equal ease. Inconclusion, the PHQ does not appear to have any advantage over the SRQ.

Chiropractic chronic low back pain sufferers and self-report assessment methods. Part II. A reliability study of the Middlesex Hospital Questionnaire and the VAS Disability Scales Questionnaire.

The subjective complaints of 41 chronic low back pain sufferers attending a chiropractic clinic were assessed twice prior to therapy with a widely used psychological self-report assessment tool, the Middlesex Hospital Questionnaire (MHQ) and a newly developed VAS Disability Scales Questionnaire (DISQ), both of which investigate various aspects of certain basic positions and activities. Reliability was generally acceptable with these two questionnaires. Subjects participating in the study were commonly found to score within the normal range on the MHQ, indicating that psychological disturbance was not a major feature of their presentation. However, mild mood disturbance was commonly reported, and a more sensitive tool may need to be developed for this type of mildly affected chronic low back pain sufferers. The DISQ generally indicated subjects were mildly to moderately affected by their low back trouble and that sitting and leisure activities were the most pain provoking. Recommendations for further development of the disability scale are made.

[The development of a new QOL Questionnaire on chemotherapy - induced emesis and vomiting--investigation of reliability and validity. Group for Investigation of QOL Questionnaire for Anti-Emetics Used in Cancer Chemotherapy. Joint Research Group for Tropisetron Double-Blind Comparative study].

A new questionnaire on QOL of patients with chemotherapy-induced emesis and vomiting was developed, and its reliability and validity were investigated in the present multi-center clinical trial. The questionnaire consisted of 15 items which included descriptive questions on appetite, feeling, sleep, mental fatigue, anxiety, pain, sputum, respiratory distress, nausea, vomiting, abdominal condition, daily life in a hospital and relationship with family, a linear analogue scale representing influence of nausea and vomiting on patient's life during 24 hours, and a face scale as the global scale. Data from 98 patients with cancer were analyzed by principal component analysis and correlation analysis. The results were summarized as follows: 1) Recollect rate was 78.1% and complete response rate was 86.0% in this QOL measurement. 2) A clear correlation was observed between appetite, feeling, nausea, vomiting and the physiological scale, between sleep, mental fatigue, anxiety, pain, abdominal condition and the psychological scale, between sputum, respiratory distress and the respiratory condition related scale, between daily life in hospital and the active scale, between relationship with family and the social relation scale. These results satisfied internal consistency. 3) As for test-retest reliability, the total score of 13 descriptive items between the day before and two days before the start of chemotherapy showed no significant difference. 4) The 13 items were grouped into physiological, the psychological, the respiratory condition related, the active and the social relation scales, and these scales belonged to a different dimension. 5) The linear analogue scale, the face scale and the total scores of 13 descriptive items correlated respectively with all of items except item of, relationship with family. 6) As for concurrent validity, vomiting frequency, severity of nausea and anorexia correlated with the physiological scale. Severity of nausea and anorexia also correlated with the psychological and active scales. 7) As a result of investigation of sensitivity, the total score of the 13 descriptive items, the linear analogue scale representing influence of nausea and vomiting on patient's life during 24 hours and the face scale revealed the poorest levels 2-3 days after chemotherapy but recovered thereafter. The aggravation of QOL of patients treated with chemotherapy was reduced in the anti-emetic administration group compared with the placebo administration group. These results suggested that this new questionnaire developed for chemotherapy-induced emesis and vomiting had sufficient validity and reliability to reflect the effects of anti-emetic drug.

A comparison of the binge eating scale, questionnaire for eating and weight patterns-revised, and eating disorder examination questionnaire with instructions with the eating disorder examination in the assessment of binge eating disorder and its symptoms.

OBJECTIVE: The current study assesses concordance between self-administered measures and a diagnostic standard for assessment of binge frequency and diagnosis of binge eating disorder (BED) in a sample of binge eaters. METHOD: The Questionnaire for Eating and Weight Patterns-Revised (QEWP-R), Binge Eating Scale (BES), two items from the Eating Disorder Examination Questionnaire with Instructions (EDE-Q-I), and the Eating Disorder Examination (EDE) were administered. Participants were 157 adults volunteering for a clinical study, of whom 129 (79%) were diagnosed with BED using the EDE as the diagnostic standard. RESULTS: In the identification of BED, the QEWP-R yielded a sensitivity value of .74 and a specificity value of .35. The BES yielded a sensitivity value of .85 and a specificity value of .20. Frequency of binge eating days and episodes on the EDE-Q-I correlated highly with the EDE (.65 and .48, respectively; p < .001). DISCUSSION: The accuracy of diagnosis and symptomatology among self-administered questionnaires is variable. The BES and the QEWP-R performed satisfactorily as initial screens for the diagnosis of BED, but were less accurate in identifying non-BED individuals and the frequency of binge eating. The EDE-Q-I most accurately assessed the frequency of binge eating.

Assessing personality features and their relations with behavioral problems in adolescents: Tridimensional Personality Questionnaire and Junior Eysenck Personality Questionnaire.

This study examines the applicability for adolescents of the Tridimensional Personality Questionnaire (TPQ), which was originally designed for adults, as compared to the Junior Eysenck Personality Questionnaire (JEPQ). The study also evaluates their inter-relationship and associations with various behavioral problems as reported by parents using the Child Behavior Checklist (CBCL). In a representative community sample of 905 adolescents, the results of internal consistency, test-retest reliability, and factor analysis showed that both the Harm Avoidance (HA) and the Novelty Seeking (NS) scales of the TPQ have sound construct validity, although the Reward Dependence (RD) scale has less so. The intercorrelation and factor analysis of the two questionnaires showed that the TPQ and the JEPQ are not simply alternative descriptions of the same construct of personality. In their associations with various behavioral problems, the scales of the TPQ are relatively more specifically associated with behavioral problems than the scales of the JEPQ. Our results provide empirical support for the applicability of the NS and the HA scales of the TPQ in adolescents, particularly in relation to behavioral problems.

Development of the Leeds Dependence Questionnaire (LDQ): a questionnaire to measure alcohol and opiate dependence in the context of a treatment evaluation package.

The Leeds Dependence Questionnaire (LDQ) has been developed as part of a treatment evaluation package. The LDQ is a 10-item, self completion questionnaire designed to measure dependence upon a variety of substances; it has been shown to be understood by users of alcohol and opiates. The questionnaire was designed to be sensitive to change over time and to be sensitive through the range from mild to severe dependence; the follow-up data are insufficient to demonstrate change over time, but are encouraging. It is expected that both clinicians and researchers will find it useful to have a single measure relating to substance use, but not limited by specific substances. All items are scored 0-1-2-3; there are no normative data. The procedure for establishing content validity is described and estimates of concurrent, discriminant and convergent validities are reported; these validities are thought to be satisfactory. A principal components analysis produced a single factor accounting for 64% of the variance. Cronbach's alpha was 0.94. Test-retest reliability was found to be 0.95.

Temporal variation of validity of self-rating questionnaires: repeated use of the General Health Questionnaire and Zung's Self-rating Depression Scale among women during antenatal and postnatal periods.

The 30-item General Health Questionnaire (GHQ) and Zung's Self-Rating Depression Scale (SDS) were distributed to 120 pregnant women 4 times--in early and late pregnancy and 5 days and 1 month after the child was born. The validity of the questionnaires was assessed against the subjects' Research Diagnostic Criteria (RDC) diagnoses. Both the GHQ and SDS sufficiently identified cases of minor mental disorder and depressive disorders respectively in early pregnancy; they lost their validity on the subsequent two occasions, but gained it again 1 month after the birth; the optimal cut-off points varied accordingly. This study suggests that the optimal cut-off point for a questionnaire should be validated against an externally determined clinical diagnosis whenever the instrument is used repeatedly on the same population.

[The Dutch version of the McGill pain questionnaire: a reliable pain questionnaire].

OBJECTIVE: To assess whether the McGill pain questionnaire, translated into Dutch (MPQ-DLV), is a reliable instrument to measure pain. DESIGN: Questionnaire study. SETTING: Faculty of Social Sciences, University of Leiden, the Netherlands. METHOD: The MPQ-DLV was administered three times to 92 patients who had physiotherapy: in group I (n = 62) twice before and four hours after physiotherapy treatment, in group II (n = 30) before, directly after and four hours after treatment. The questionnaire consisted of questions to determine (a) the quality and intensity, (b) the localisation and evolution of the pain, (c) the effects of the pain on quality of life and further (d) visual analog pain intensity scales. Subsets of questions were combined into nine indices. For all indices on all three occasions Cronbach's alpha coefficients were determined. Moreover, test-retest correlation coefficients were determined between the scores of the first and second, the first and third, and the second and third occasions. RESULTS: The test-retest correlations of the nine indices and the visual analog pain intensity scales ranged from 0.62 to 0.93 (median: 0.84). Cronbach's alpha coefficients for the indices varied between 0.61 and 0.85 (median: 0.72). CONCLUSION: The MPQ-DLV is a reliable instrument for measuring pain.

Development and validation of the health assessment questionnaire II: a revised version of the health assessment questionnaire.

OBJECTIVE: The Health Assessment Questionnaire (HAQ) has become the most common tool for measuring functional status in rheumatology. However, the HAQ is long (34 questions, including 20 concerning activities of daily living and 14 relating to the use of aids and devices) and somewhat burdensome to score, has some floor effects, and has psychometric problems relating to linearity and confusing items. We undertook this study to develop and validate a revised version of the HAQ (the HAQ-II). METHODS: Using Rasch analysis and a 31-question item bank, including 20 HAQ items, the 10-item HAQ-II was developed. Five original items from the HAQ were retained. We studied the HAQ-II in 14,038 patients with rheumatic disease over a 2-year period to determine its validity and reliability. RESULTS: The HAQ-II was reliable (reliability of 0.88, compared with 0.83 for the HAQ), measured disability over a longer scale than the HAQ, and had no nonfitting items and no gaps. Compared with the HAQ, modified HAQ, and Medical Outcomes Study Short Form 36 physical function scale, the HAQ-II was as well correlated or better correlated with clinical and outcome variables. The HAQ-II performed as well as the HAQ in a clinical trial and in prediction of mortality and work disability. The mean difference between the HAQ and HAQ-II scores was 0.02 units. CONCLUSION: The HAQ-II is a reliable and valid 10-item questionnaire that performs at least as well as the HAQ and is simpler to administer and score. Conversion from HAQ to HAQ-II and from HAQ-II to HAQ for research purposes is simple and reliable. The HAQ-II can be used in all places where the HAQ is now used, and it may prove to be easier to use in the clinic.

The health assessment questionnaire disability index and scleroderma health assessment questionnaire in scleroderma trials: an evaluation of their measurement properties.

OBJECTIVE: To evaluate the measurement properties of the Health Assessment Questionnaire (HAQ) disability index (DI) for group comparisons in scleroderma trials, and to determine if the Scleroderma Health Assessment Questionnaire (SHAQ) visual analog scales confer any measurement advantage over the HAQ DI. METHODS: A computer search for articles describing the use of the HAQ DI and SHAQ in scleroderma was performed. Evidence supporting the sensibility, reliability, validity, and responsiveness of these measures was evaluated. RESULTS: The SHAQ has incremental face and content validity over the HAQ DI because it addresses scleroderma-specific manifestations that also contribute to disability. The HAQ DI has good concurrent validity, construct validity, and predictive validity. Whether SHAQ confers incremental construct, concurrent, or predictive validity over the HAQ DI is uncertain. The HAQ DI appears more reliable than the SHAQ; however, reliability studies provide insufficient data to ascertain if minimum standards have been achieved. Responsiveness of the HAQ DI subscales has been demonstrated. CONCLUSION: The SHAQ has incremental face and content validity over the HAQ DI. The HAQ DI has greater reliability and demonstrated construct, concurrent, and predictive validity. Further investigation into the measurement properties of the HAQ DI and SHAQ visual analog scales, and their relation to the required standards of measurement is needed.

The development and psychometric validation of a brain cancer quality-of-life questionnaire for use in combination with general cancer-specific questionnaires.

A self-report questionnaire module consisting of 24 items, comprising 5 scales and 7 single items, has been developed for measuring health-related quality of life in patients with brain cancer. Module development proceeded through several stages, including a listing of patient, family and health care professional concerns, the writing of items, field testing in 105 patients with brain cancer and subsequent item reduction and scale construction after multitrait scaling analysis and assessment of internal consistency (Cronbach's coefficient alpha). The final version of the module exhibits reasonable test-retest stability over a period of one week. Differences in the responses between patients with recently-diagnosed and recurrent cancer and between patients with a Karnofsky Performance Score (KPS) of 50-70 and 80-100 were in the expected direction, indicating that the module of questions is responsive to differing conditions. Patients with either mental confusion, motor deficit or dysphasia indicated problems in several domains and single items as compared to patients without these neurological deficits. Thus, differences in the responses to the items in the brain cancer module appear to reflect differences in neurological status. In addition, deteriorating neurological status was accompanied by a marked increase in emotional distress, future uncertainty and motor dysfunction. A comparison of the responses in the module with the KPS and with a modified Barthel Activities of Daily Living Index (BADLI) shows moderate correlations, primarily with scales and items that pertain to motor dysfunction, while other scales (such as emotional distress, visual disorder and communication deficit) and most single items are not associated with the KPS or BADLI. Since the emotional distress scale of the module was found to be highly correlated with the emotional function scale of the EORTC QLQ-C30, it could be omitted when the module is used in combination with the QLQ-C30. This would reduce the module to a total of 20 items with four scales and seven single items. The intention is to combine this module of questions with other core or general quality-of-life questionnaires when studying patients with brain cancer in clinical trials.

Responsiveness of the coronary revascularisation outcome questionnaire compared with the SF-36 and Seattle Angina Questionnaire.

We describe a comparison of the responsiveness of three validated instruments when used with patients undergoing coronary bypass surgery (CABG) and angioplasty (PTCA). Patients were randomly selected to receive the Coronary Revascularisation Outcome Questionnaire (CROQ), and either the Seattle Angina Questionnaire (SAQ), or the SF-36 before and 3 months after coronary revascularisation. At total of 199 patients (127 CABG, 72 PTCA) completed the CROQ; 55/72 CABG and 34/38 PTCA patients also completed the SAQ or SF-36, respectively. Effect sizes and standardised response means were calculated as change over the 3-month period for scales measuring similar constructs on each instrument. We used bootstrap estimation to derive 95% confidence intervals for differences in the responsiveness indices. For CABG, the CROQ demonstrated significantly greater change in psychosocial functioning than the SF-36, but less than the SAQ. For PTCA, the CROQ showed greater change for symptoms than the SAQ, but the SAQ was more responsive in terms of physical functioning; and the CROQ showed significantly greater change than the SF-36 for psychosocial functioning. There were no other significant differences between similar scales on the three instruments. In conclusion, the CROQ was as responsive as the disease-specific SAQ and more responsive than the generic SF-36.

The Dartmouth Pain Questionnaire: an adjunct to the McGill Pain Questionnaire.

The Dartmouth Pain Questionnaire is presented as an adjunct to the McGill Pain Questionnaire. It adds assessment of 4 objective measurements (pain complaints, somatic interventions, impaired functioning, and remaining positive aspects of function) and 1 subjective measure (changes in self-esteem since onset of pain). The entire device fits on one piece of paper and patients easily learn to self-administer it. Standardization results show acceptable levels of reliability and validity.

Relationships between the Food Expectancy Questionnaire (FEQ) and the Food Frequency Questionnaire (FFQ).

The outcome expectancies of 250 respondents were examined using the Food Expectancy Questionnaire (FEQ), comparing expectancies about four different foods: fruit, vegetables, chocolate and sweets and plain biscuits. These expectancies were related to diet as assessed by a Food Frequency Questionnaire. As with alcohol expectancies [Jones, B. T., Corbin, W. & Fromme, K. (2001). A review of expectancy theory and alcohol consumption. Addiction, 96, 57-72], on which this research was modelled, positive and negative outcomes were the main factors for all foods, accounting jointly for between 33 and 40% of expectancy variance in factor analysis and predicting as much as 16% of the variance in relevant food intake measures by linear regression. Expected positive and negative outcomes of eating were predominantly immediate psychological after-effects, rather than including orosensory experiences, or longer-term effects on health or well-being. Other expectancies varied from food to food. FEQ expectancies for different foods have similar factor structure and were related to self-reported diet, the FEQ therefore shows promise as a means of modelling cognitions about eating.
