Psychometric evaluation of an interview-administered version of the Kessler 10-item questionnaire (K10) for measuring psychological distress in rural Bangladesh.

ABSTRACT:

Objective

The aim of this study was to translate, adapt and validate the Kessler 10-item questionnaire (K10) for measuring psychological distress in rural Bangladesh.

Design

Cohort study.

Setting

Narail district, Bangladesh.

Participants

A random sample of 2425 adults of age 18-90 years was recruited.

Outcome measure

Validation of the K10 was the major outcome. Sociodemographic factors were measured to assess if the K10 needed adjustment for factors such as age or gender. The Rasch measurement model was used for the validation, and RUMM 2030 and SPSS V.24 software were used for analyses.

Results

Initial inspection of the total sample showed poor overall fit. A sample size of 300, which is more satiated for Rasch analysis, also showed poor overall fit, as indicated by a significant item-trait interaction (?²= 262.27, df=40, p<0.001) and item fit residual values (mean=-0.25, SD=2.49). Of 10 items, five items were disordered thresholds, and seven items showed misfit, suggesting problems with the response format and items. After removing three items ('feel tired', 'depressed' and 'worthless') and changing the Likert scale categories from five to four categories, the remaining seven items showed ordered threshold. A revised seven-item scale has shown adequate internal consistency, with no evidence of multidimensionality, no differential item functioning on age and gender, and no signs of local dependency.

Conclusions

Analysis of the psychometric validity of K10 using the Rasch model showed that 10 items are not appropriate for measuring psychological distress in rural Bangladesh. A modified version of seven items (K7) with four response categories would provide a psychometrically more robust scale than the original K10. The study findings suggest repeating the K7 version in other remote areas for further validation can substantiate an efficient screening tool for measuring psychological distress among the general Bangladeshi population.

Project description:OBJECTIVES:This investigation expected to validate the psychometric properties of the modified seven-item Kessler psychological distress scale (K7) for measuring psychological distress in healthy rural population of Bangladesh. DESIGN:Cross-sectional study. SETTING:Narail district, Bangladesh. PARTICIPANTS:A random sample of 300 adults of age 18-90 years were recruited. Face-to-face interviews were conducted between July and August 2018 using an Android phone installed with a mobile data collection application known as CommCare. OUTCOME MEASURE:Validation of the K7 was the major outcome. Sociodemographic factors were measured to assess for Differential Item Functioning to check if the tool functions equally in different factors. Rasch analysis was carried out for the validation of the K7 scale in the healthy rural population of Bangladesh. RUMM2030 was used for the analyses. RESULTS:Results showed good overall fit, as indicated by a non-significant item-trait interaction (?2=44.54, df=28, p=0.0245) compared with a Bonferroni adjusted p value of 0.007. Both item fit (mean=0.30, SD 1.22) and person fit residuals (mean=-0.18, SD 0.85) showed perfect fit. Reliability was very good as indicated by a Person Separation Index=0.85?and Cronbach's alpha=0.89. All individual items were ordered thresholds. The K7 scale showed adequate reliability, unidimensionality and was free from local dependency. The K7 scale also showed similar functioning for adults and older adults, males and females, no education and any level of education, and at least some financial instability versus no financial instability. CONCLUSIONS:Validation of K7 scale confirmed that the tool is suitable for measuring psychological distress among the rural Bangladeshi population. Further research should validate the K7 scale in different rural settings in Bangladesh to determine a valid cut-off score for assessment of severity levels of psychological distress. The K7 scale should also be tested in other developing countries where sociodemographic characteristics are similar to those of Bangladesh.

Project description:BackgroundThis study aimed to validate the psychometric properties of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) questionnaire for use in a rural district of Bangladesh.MethodsThis cross-sectional study recruited a multi-stage cluster random sample of 2425 participants from the rural district Narail of Bangladesh in May-July 2017. Rasch analysis was carried out using the sampled participants, as well as multiple validation random sub-samples of 300 participants, to validate four domains of the WHOQOL-BREF questionnaire: physical, psychological, social and environmental.ResultsThe original WHOQOL-BREF appeared to be a poor fit for both sampled and sub-sampled group of participants in Narail district in all underlying domains: physical, psychological, social and environmental. Two items (sleep and work capacity) from the physical domain, two items (personal belief and negative feelings) from the psychological domain and three items (home environment, health care and transport) from the environment domain were excluded for goodness of fit of the Rasch model. The social domain exhibited reasonably reliable fitness while fulfilling all the assumptions of the Rasch model. A modified version of the WHOQOL-BREF questionnaire using five-items for the physical ([Formula: see text] = 36.47, p = 0.013, Person Separation Index (PSI) = 0.773), four-items for the psychological ([Formula: see text] = 28.30, p = 0.029, PSI = 0.708) and five-items for the environmental ([Formula: see text] = 36.97, p = 0.011, PSI = 0.804) domain was applied, which showed adequate internal consistency, reliability, unidimensionality, and similar functioning for different age-sex distributions.ConclusionsThe modified WHOQOL-BREF questionnaire translated into Bengali language appeared to be a valid tool for measuring quality of life in a typical rural district in Bangladesh. Despite some limitations of the modified WHOQOL-BREF questionnaire, further application of Rasch analysis using this version or an improved one in other representative rural areas of Bangladesh is recommended to assess the external validity of the outcomes of this study and to determine the efficacy of this tool to measure the quality of life at the national rural level.
