Reliability and validity of the Functional Status Questionnaire

The Functional Status Questionnaire (FSQ) originally was developed to allow the comprehensive and efficient assessment of physical, psychosocial, social, and role functioning in ambulatory patients. It is a self-administered survey that takes approximately 15 min to complete and can be scored to produce a one-page report for clinicians to use in their practices. It has been translated into Swedish, French, and German. Since the FSQ was first published, it has been used in a variety of other settings, including assessment of the impact of variations in hospital practice patterns, the study of relationships between hospital processes of care and outcomes, and other applications, including randomized controlled trials of pharmaceuticals. In this paper we provide selected data on the reliability and validity of the FSQ in different populations. Many of the data are from previously published studies. However, because of the emphasis of this issue of Quality of Life Research, we also present new data from two large studies of persons over the age of 65.

Reliability and validity of the Satisfaction with Hospital Care Questionnaire.

OBJECTIVE: To establish the psychometric properties of the Satisfaction with Hospital Care Questionnaire (SHCQ) for measuring patient satisfaction and evaluations of hospital care quality. DESIGN AND PARTICIPANTS: Patients (n = 275) and staff members (n = 83) of four hospital wards completed the 57-item SHCQ addressing 13 aspects of care. Staff members completed the SHCQ from the patient's perspective. The data were analyzed within the framework of generalizability theory. MAIN OUTCOME MEASURES: Generalizability coefficients (GCs) and standard errors of measurement (SEs). RESULTS: GCs indicating differentiation among patients with different overall levels of satisfaction (SHCQ mean scores) were high (> 0.90). GCs indicating differentiation among patients as to satisfaction with aspects of care (SHCQ scale scores) were generally satisfactory (> 0.75) to high. Patients agreed well on overall level of hospital care quality (GCs > 0.90) and differentiated reliably (GCs > 0.80) among aspects of care. No differentiation among wards was found with respect to quality of care. Patients and staff agreed to a considerable extent (0.78) on ranking the SHCQ items on care quality, but staff ratings were lower. Reliability and validity of patients' evaluations of quality of hospital care varied according to aspect of care. CONCLUSIONS: The SHCQ reliably establishes both patient satisfaction and overall quality of hospital care. Whereas patients' ratings may be too lenient, their ranking of the items on care quality appears to be valid, and is therefore suitable for monitoring and improving hospital care. Within scales, however, results should be interpreted more cautiously: for some items, patients cannot really tell the difference in quality of care.

Validity and repeatability of the EPIC-Norfolk Physical Activity Questionnaire

BACKGROUND: Physical activity is an important lifestyle which is often poorly assessed in epidemiological studies. The European Prospective Investigation into Cancer Study-Norfolk cohort (EPIC-Norfolk), a large population-based cohort study, has developed a comprehensive questionnaire to assess activity in different domains of life aimed at assessing total energy expenditure. We report the repeatability of this instrument and its validity against repeated objective measures of fitness and energy expenditure undertaken throughout the time frame of reference of the questionnaire. METHODS: The validity of the instrument was measured in 173 individuals randomly selected from a continuing population-based cohort study. Energy expenditure was assessed by four separate episodes of 4-day heart-rate monitoring, a method previously validated against whole body calorimetry and doubly-labelled water. Cardio-respiratory fitness was assessed by four repeated measures of sub-maximum oxygen uptake. At the end of the 12-month period, participants completed the physical activity questionnaire that assesses past-year activity at home, work and in recreation. Repeatability was assessed in a separate group of 399 randomly selected participants in EPIC who completed the physical activity questionnaire twice with a 3-month interval. RESULTS: The age- and sex-adjusted correlation between the objective measure of daytime energy expenditure and the sum of recreational and occupational reported physical activity (in MET h per week) was 0.28 (P < 0.001). The reported time spent in vigorous activity was correlated with cardio-respiratory fitness (0.16, P < 0.05) and with the proportion of time when energy expenditure was more than five times basal (0.17, P < 0.05). The repeatability of the sum of recreational and occupational reported activity was high, r = 0.73. CONCLUSIONS: The indices of physical activity derived from this questionnaire have levels of validity and repeatability comparable to other physical activity instruments that are used in large epidemiological studies and which have undergone such intense development and testing.     

Reliability and validity of the Dutch version of the Readiness to Change Questionnaire

The aim of the present study was to evaluate the psychometric properties of the Dutch version of the Readiness to Change Questionnaire (RCQ-D). The subjects were 246 excessive drinkers admitted to an addiction treatment centre and 54 offenders convicted of an alcohol-related crime in The Netherlands. The factor structure of the RCQ-D for the two samples combined was found to be consistent with the three-factor structure established for the original RCQ. The reliability of the items for each scale was found to be satisfactory. Allocated stage of change showed significant differences between the different subsamples. As expected, the scale scores for adjacent stages of change showed significantly higher inter-correlations than the scale scores for non-adjacent stages. Additionally, the negatively formulated items from the pre-contemplation scale were reformulated positively and their internal consistency tested among the offender sample. The positively formulated pre-contemplation items showed a higher alpha value than the negatively formulated items. We therefore suggest that the positively formulated items should replace the negatively formulated ones.

Questionnaire techniques in assessing acne handicap: Reliability and validity study

The purpose of this study was to examine and compare the reliability and validity of two acne-specific measures, the Cardiff Acne Disability Index (CADI), the Acne Disability Index (ADI) and a general health status instrument, the United Kingdom Sickness Impact Profile (UKSIP). The test-retest reliability was carried out for the UKSIP, ADI and CADI with an interval of 10 days in 70 patients with acne. The correlation coefficient for the overall UKSIP score was high (r=0.99, p<0.001) for the CADI was 0.96 (p<0.001) and for the ADI was 0.98 (p<0.001). Individual category score correlations in the UKSIP and ADI were greater than 0.83. Tests of internal consistency of the instruments scored highly. A further 100 patients with acne and 50 controls completed all three instruments. The overall UKSIP mean score of patients was 5.6 (sd=4.7) and of controls was 0.45. The ADI mean patient score was 40.3%, controls 17.6%. The CADI mean patient score was 42.1%, controls 13.2%. The CADI was the only instrument that correlated with the clinical acne severity score (p<0.05); the UKSIP score correlated with the CADI score (p<0.05) but not with the ADI score. This study has established aspects of the reliability and validity of the UKSIP, the ADI and the CADI.     

Reliability and validity of the Norwegian version of the Functional Outcomes of Sleep Questionnaire

The aim of this study was to validate the Norwegian version of a self-administered 30-item quality of life questionnaire designed to assess disorders of excessive sleepiness, the Functional Outcomes of Sleep Questionnaire (FOSQ). In total 226 patients previously evaluated for obstructive sleep apnea were included in the study. The patients received a postal questionnaire with the FOSQ, the Short Form 36 (SF-36) questionnaire, and a scale for assessment of excessive daytime sleepiness, the Epworth sleepiness scale (ESS). Among the 178 respondents, all five subscales of the FOSQ showed good internal consistency reliability (Cronbach's alpha = 0.84-0.93). Test-retest on average 18 days apart was satisfactory with intraclass correlation coefficients ranging from 0.61 to 0.86. The pattern of Spearman's rank correlation coefficients between FOSQ scales and related and unrelated scales SF-36 scales gave support to the construct validity of the FOSQ. In conclusion, the Norwegian translation of the FOSQ showed satisfactory internal consistency reliability, test-retest reliability and construct validity, in line with the original version.

Concurrent validity of the International Physical Activity Questionnaire (IPAQ) in an liyiyiu Aschii (Cree) community

BACKGROUND: Culturally acceptable and validated instruments for assessing physical activity among Indigenous Peoples are lacking. Given the current trends in obesity, health behaviour surveillance tools are needed to evaluate trends and to determine the effectiveness of health promotion efforts aimed at curbing the obesity epidemic. OBJECTIVE: To evaluate whether the International Physical Activity Questionnaire (IPAQ) scores correlate with anthropometric indices in an liyiyiu Aschii community (Cree Territory of northern Quebec, Canada). METHODS: A cross-sectional study was carried out in a Cree community as part of a larger research effort entitled, "Nituuchischaayihitaau Aschii: A Multi-Community Environment-and-Health Longitudinal Study in liyiyiu Aschii". Randomly selected adult participants (n = 161) underwent an anthropometric assessment and answered the IPAQ which was administered by bilingual research assistants. Concurrent validity of the IPAQ was evaluated by the extent to which the physical activity scores were related to anthropometric measures. RESULTS: Significant inverse correlations were observed between the IPAQ Total MET score and % body fat (r = -.19, p < or = 0.01) and the IPAQ Vigorous MET score and % body fat (r = -.26, p < or = 0.001), but not for waist circumference or BMI. Walkers (6-7 days/wk for > or = 60 minutes/day), however, had a waist circumference that was, on average, 5 cm smaller than non-walkers in age- and sex-adjusted linear regression analyses (beta = -4.97; SE = 2.5; p < or = 0.05). DISCUSSION: The results indicate that the IPAQ holds promise as a culturally adaptable questionnaire for the liyiyiuch. However, modifications will help improve its acceptability for community members.
