Development of a Short Questionnaire to Measure an Extended Set of Job Demands,Job Resources,and Positive Health Outcomes: The New Brief Job Stress Questionnaire

This study aimed to investigate the reliability and construct validity of a new version of the Brief Job Stress Questionnaire (New BJSQ), which measures an extended set of psychosocial factors at work by adding new scales/items to the current version of the BJSQ. Additional scales/items were extensively collected from theoretical job stress models and similar questionnaires in several countries. Scales/items were field-tested and refined through a pilot internet survey. Finally, an 84-item questionnaire (141 items in total when combined with the current BJSQ) was developed. A nationally representative survey was administered to employees in Japan (n=1,633) to examine the reliability and construct validity. Most scales showed acceptable levels of internal consistency and test-retest reliability. Principal component analyses showed that the first factor explained 50% or greater proportion of the variance in most scales. A scale factor analysis and a correlation analysis showed that these scales fit the theoretical expectations. These findings provided a piece of evidence that the New BJSQ scales are reliable and valid. Although more detailed content and construct validity should be examined in future study, the New BJSQ is a useful instrument to evaluate psychosocial work environment and positive mental health outcomes in the current workplace.     

The development and validation of a short measure of functioning and well being for individuals with Parkinson's disease

Parkinson's disease is a common degenerative neurological condition. A number of general health status measures exist but these may not address areas salient to specific diseases. We report here the development and validation of a short 39 item health status questionnaire for use in Parkinson's disease. Questionnaire items, generated from indepth interviews with people with Parkinson's disease, were developed into a 65 item questionnaire. Data from a postal survey using the 65 item questionnaire were statistically analysed to produce a shorter questionnaire with 39 items and eight scales addressing different dimensions of Parkinson's disease. A second postal survey was conducted in order to assess the reliability and validity of the new 39 item questionnaire. The final questionnaire, referred to here as the 39 item Parkinson's Disease Questionnaire (PDQ-39), proved to have satisfactory internal and test-retest reliability, and construct validity in relation to other measures, reported by respondents with Parkinson's disease.

Validity of a job stressors measurement scale in nursing staff: the nursing stress scale]

BACKGROUND: The aim of this work was to determine the reliability and construct validity of a scale intended to measure job stressors to which hospital nursing staff may be exposed. SUBJECTS AND METHODS: The nursing stress scale contains 34 stressors. The scale's trans-cultural adaptation was carried out by means of the translation-back translation method. Validation was conducted on a random sample of 201 health professionals in a public hospital in Valencia. The reliability of the scale was assessed after its readministration on a sub-sample of 30 nursing professionals, with a 15 day interval. The construct validity was obtained through the correlation of the scale with another two scales: The 28 item version of Goldberg's General Health Questionnaire and 7 dimensions of the Health questionnaire SF-36. RESULTS: The scale in Spanish language contains 34 items after eliminating the first item from the original scale (N1: computer failure) and including a new item (E1: Frequent job interruptions). The distribution of scores obtained in the initial administration of the scale and fifteen days later do not differ statistically. The Cronbach's alfa coefficient is 0.92 for the total scale and in each of the sub-scales ranges between 0. 83 and 0.49. The correlation between the scale and the GHQ-28 items questionnaire is 0.34. For each one of the seven dimensions of the SF-36 questionnaire the correlations range between -0.21 and -0.31. CONCLUSION: The nursing stress scale is a useful instrument for measuring possible stressors in this collective. It has high internal consistency and construct validity, as does the original American version, however reliability is moderate.     

Translation and psychometric testing of the Basque version of the SF-36 Health Survey

Introduction: The primary goals of this study were to adapt the Short Form-36 (SF-36) questionnaire to the Basque language and to assess the translated questionnaires psychometric properties. Methods: Two pilot studies and a field study were conducted in 1999. The pathologies selected were hypertension, eating disorders, back pain, and HIV infection; blood donors were also included. The analyses conducted at item-level were: item internal consistency, item discriminant validity, equal item variance, and equal item-scale correlation. Internal consistency was measured at the scale level. Reproducibility, convergent validity and discriminant validity were also examined. Results: 285 individuals took part in the study; sufficient data were obtained for 265 (93%). All items correlated higher than 0.4 with their hypothesized scales. Within each scale, item standard deviations were similar. Item-scale correlations were also similar. Cronbachs alpha coefficients varied from 0.76 to 0.92. In the test-retest reliability study, which included 54 additional individuals, all scales were above 0.50. Regarding the inter-scale correlation, the majority exceeded the 0.40 coefficient. In the correlation of similar scales of the SF-36 and the Nottingham Health Profile, intraclass correlation coefficient results ranged from 0.29 to 0.62. Conclusions: These results confirm that this new version of the SF-36 has been translated and adapted correctly for the Basque language and that it fulfils, at least partially, the psychometric properties required for this instrument. Further studies, however, are needed to completely validate the Basque version of the SF-36.

Reliability and validity of the short form of the child health questionnaire for parents (CHQ-PF28) in large random school based and general population samples

STUDY OBJECTIVES: This study assessed the feasibility, reliability, and validity of the 28 item short child health questionnaire parent form (CHQ-PF28) containing the same 13 scales, but only a subset of the items in the widely used 50 item CHQ-PF50. DESIGN: Questionnaires were sent to a random regional sample of 2040 parents of schoolchildren (4-13 years); in a random subgroup test-retest reliability was assessed (n = 234). Additionally, the study assessed CHQ-PF28 score distributions and internal consistencies in a nationwide general population sample of (parents of) children aged 4-11 (n = 2474) from Statistics Netherlands. MAIN RESULTS: Response was 70%. In the school and general population samples seven scales showed ceiling effects. Both CHQ summary measures and one multi-item scale showed adequate internal consistency in both samples (Cronbach's alpha>0.70). One summary measure and one scale showed excellent test-retest reliability (intraclass correlation coefficient >0.70); seven scales showed moderate test-retest reliability (intraclass correlation coefficient 0.50-0.70). The CHQ could discriminate between a subgroup with no parent reported chronic conditions (n = 954) and subgroups with asthma (n = 134), frequent headaches (n = 42), and with problems with hearing (n = 38) (Cohen's effect sizes 0.12-0.92; p<0.05 for 39 of 42 comparisons). CONCLUSIONS: This study showed that the CHQ-PF28 resulted in score distributions, and discriminative validity that are comparable to its longer counterpart, but that the internal consistency of most individual scales was low. In community health applications, the CHQ-PF28 may be an acceptable alternative for the longer CHQ-PF50 if the summary measures suffice and reliable estimates of each separate CHQ scale are not required.     

Measuring access to social capital: the validity and reliability of the Resource Generator-UK and its association with common mental disorder

Resource generators measure an individual's access to social resources within their social network. They can facilitate the analysis of how access to these resources may assist recovery from illness. As these instruments are culture and context dependent different versions need to be validated for different populations. Further, they are yet to be subjected to a thorough content validation and their reliability and validity have not been established beyond an examination of their internal scales. This paper reports the validity and reliability of a version suitable for general population use in the UK. Firstly, a qualitative process of item selection and review through focus groups and an expert panel ensured that the resource items were relevant. Also, cognitive interviews identified any significant problems prior to extensive piloting. Then we examined its internal domains using Mokken scaling in a small general population survey (n=295). Its concurrent validity with a similar instrument was tested in a further pilot (n=335) and these findings were supported by a known-group validity study (n=65). Its reliability was established in a test-retest study (n=47) in addition to an examination of the reliability coefficients of the internal scales. We found that the Resource Generator-UK has good psychometric properties, though there is some variation in performance between items and scales. Further, we found an inverse relationship with common mental disorder in the second pilot we undertook.     

Validation of the Abuse Screening Inventory (ASI)

AIMS: To assess the test-retest reliability and concurrent validity of the Abuse Screening Inventory (ASI) in a female sample. METHOD: The ASI comprises 16 items concerning four kinds of abuse: psychological, physical, and sexual abuse, and abuse in healthcare. A randomized sample of 699 women answered the ASI once. Six months later 53 of them answered the ASI again and were interviewed. To assess concurrent validity, answers in the interviews were considered as the gold standard and the ASI as the diagnostic test. RESULTS: The ASI presented good overall test-retest reliability ranging from 81% to 96% for separate items. The ASI separated very well abused from non-abused women. No false positive answers were found. Sensitivity ranged from 72% to 82% for items concerning abuse. CONCLUSION: The ASI is a short abuse screening questionnaire that had acceptable validity and test-retest reliability in a random female Swedish sample.     

The General Practice Assessment Survey (GPAS): tests of data quality and measurement properties

OBJECTIVES: The aim of this study was to describe the psychometric properties of the General Practice Assessment Survey (GPAS) and its acceptability to patients in the UK. GPAS comprises seven multiple item scales and two single item scales addressing nine key areas of primary care activity (access, technical care, communication, inter-personal care, trust, knowledge of patient, nursing care, receptionists and continuity of care). A further four single items relate to patients' perceptions of the GP's role in referral and co-ordination of care, their willingness to recommend their GP and their overall satisfaction with care received. METHODS: Two hundred consecutive patients attending routine consulting sessions at 55 inner London practices were invited to complete the GPAS questionnaire. The acceptability, reliability and validity of GPAS was assessed using standard psychometric techniques. RESULTS: Out of 11 000 patients, 7247 (66%) completed a questionnaire in a GP surgery. Fifty-five out of a separate sample of 77 patients attending one practice completed a second questionnaire mailed to them 1 week following their attendance. GPAS was acceptable to patients as evidenced by low proportions of missing data for all items, and a full range of possible scores for all but one of the nine scales. Reliability of the instrument was good. Multiple item scales had excellent internal consistency, high item-total correlations, and test-retest reliability. Scaling assumptions were confirmed, with six of the seven scales achieving 100% scaling success (convergent and discriminant validity). Construct validity was evident, although this requires further evaluation against external measures. CONCLUSIONS: GPAS is a useful instrument for assessing several important dimensions of primary care. It is acceptable, reliable and valid, and has the potential for versatility in mode of administration. It will be a useful instrument for practices, primary care groups and primary care researchers evaluating key areas of primary care activity. Further work is required to evaluate its performance in non-inner-city settings and to evaluate further its validity against external criteria.

Development of the Short Form Endometriosis Health Profile Questionnaire: The EHP-5

OBJECTIVE: To develop and validate a short form version of the Endometriosis Health Profile-30 questionnaire which consists of a 30-item core questionnaire and a 23 item modular questionnaire. METHODS: Three studies were carried out to develop the Endometriosis Health Profile-5. Study 1: a short form version of the Endometriosis Health Profile-30 core questionnaire was developed. Study 2: the results were verified in a new data set. Study 3: a short form version of the 23 item modular questionnaire was produced. The modular questionnaire contains six dimensions which may not be applicable to every woman with endometriosis and is used to supplement the five scales on the core questionnaire when required. RESULTS: The final instrument contained 11 items: five items from the core questionnaire and six items from the modular questionnaire. The 95% confidence intervals for Study 1 indicated that the scale scores overlapped with each item score and were confirmed in the second analysis (study 2). Each item was most highly correlated to its parent scale and less with the remaining four core questionnaire scales which was verified in study 2. In both studies all correlations were significant at the 0.01 level (two tailed test). CONCLUSION: The Endometriosis Health Profile-5 is a reliable and valid short form questionnaire which can also be supplemented with a short form version of the modular questionnaire when required. It will be especially useful in clinical settings where a short and economical endometriosis health status measure is required.     

Chinese SF-36 Health Survey: translation,cultural adaptation,validation, and normalisation

STUDY OBJECTIVE: To develop a self administered Chinese (mainland) version of the Short-Form Health Survey (SF-36) for use in health related quality of life measurements in China. DESIGN: A three stage protocol was followed including translation, tests of scaling construction and scoring assumptions, validation, and normalisation. SETTING: 1000 households in 18 communities of Hangzhou. PARTICIPANTS: 1688 respondents recruited by multi-stage mixed sampling. Main results: The assumption of equal intervals was violated for the vitality and mental health scales. The recoded item values were used to calculate scale scores. The clustering and ordering of item means was the same as that of the source and other two Chinese versions. The items in each scale had similar standard deviations except those in the physical functioning, boduily pain, social functioning scales. The item hypothesised scale correlations were identical for all except the social functioning and vitality scales. Convergent validity and discriminant validity were satisfactory for all except the social functioning scale. Cronbach's alpha coefficients ranged from 0.72 to 0.88 except 0.39 for the social functioning scale and 0.66 for the vitality scale. Two weeks test-retest reliability coefficients ranged from 0.66 to 0.94. Factor analysis identified two principal components explaining 56.3% of the total variance. The Chinese SF-36 could distinguish known groups. CONCLUSIONS: This study suggested that the Chinese (mainland) version of the SF-36 functioned in the general population of Hangzhou, China quite similarly to the original American population tested. Caution is recommended in the interpretation of the social functioning and vitality scales pending further studies.     

Development and Validity of a General Nutrition Knowledge Questionnaire (GNKQ) for Chinese Adults

Nutrition knowledge refers to understanding concepts and processes related to nutrition and health, proven to be an essential determinant of healthy eating. However, partially due to the lack of nutrition knowledge and unhealthy eating patterns, more and more Chinese people face overweight, obesity, and a high risk of suffering from various chronic diseases. This study aimed to develop a general nutritional knowledge questionnaire (GNKQ) in a Chinese context to diagnose and improve nutrition knowledge education for Chinese people. The newly adapted questionnaire was based on the Turkey version of GNKQ, and absorbed dietary recommendations in a Chinese context. It was first validated by four nutrition experts, then tested by eleven volunteers (one public nutritionist, one preventive medicine graduate student, and nine psychology graduate students). Finally, the questionnaire was tested by 278 participants, including 175 adults, to determine internal consistency, content validity, and convergent validity. Moreover, the construct validity was evaluated by comparing the differences between 50 students in nutrition-related majors and 53 students in nutrition-unrelated majors. The final Chinese version of GNKQ kept 32 questions with 68 items after deleting some questions based on item difficulty and discrimination. The data showed that the overall internal consistency coefficient was 0.885, and the test-retest reliability was 0.769, p < 0.001. Students majoring in nutrition had larger scores than in nutrition-unrelated majors. The convergent validity for each demographic variable was consistent with previous studies, such as larger nutrition knowledge scores for females and those with a higher education. Therefore, the revised Chinese version of GNKQ showed good reliability and validity, indicating that it could be an effective tool to assess the nutrition knowledge of Chinese adults.

Developing a questionnaire on the quality of working life for female medical and healthcare professionals

This study aimed to develop a questionnaire on the quality of working life among female medical and healthcare professionals and examine its validity and reliability. The questionnaire was developed from an item pool drawing on the literature. The four trait scales included 40 items, covering female-specific stress in continuing a career, stress of lifestyle in maintaining personal values, job satisfaction and social support network. The questionnaire’s validity and reliability were assessed using data from 1,784 female doctors, dentists, and nurses. Validity was examined using exploratory factor analysis on each trait for construct validity, and multitrait scaling analysis for convergent and discriminant validity. Reliability was tested using Cronbach’s alpha for trait subscales and scales. Exploratory factor analysis on each trait was convergent. One trait derived three subscales, and another two. The remaining two traits were convergent for one factor. Multitrait scaling analysis showed that all scales and subscales were independent. The questionnaire was therefore internally consistent and had construct validity. Cronbach’s alpha was 0.85 for the total and between 0.72 and 0.83 for the subscales. These results validate the four-trait combination questionnaire and suggest that it would be suitable for use in future research, perhaps in combination with other existing scales.
