Translation and adaptation of adult self report: A tool for assessment of adult psychopathology.

ABSTRACT

OBJECTIVE: To translate, adapt and validate the Adult Self-Report tool in Urdu language, and to establish internal consistency of its subscales. METHODS: The cross-sectional study was conducted from September 2017 to August 2018 at the National Institute of Psychology, Quaid-i-Azam University, Islamabad, Pakistan, and comprised adult stable psychiatric outpatients and non-clinical subjects from the community. After forward and backward translation of Adult Self-Report, the tool was tested on the subjects who responded on a three-point Likert scale from 'never' to 'very often'. The items were grouped under eight subscales. Data was analysed using SPSS 22. RESULTS: Of the 768 participants, 408(53%) were outpatients and 360(47%) were non-clinical subjects. The overall age range was 18-59 years. The tool was found to be effective for Pakistani sample, with root mean square error of approximation (0.03), comparative fit index (0.94) and Tucker-Lewis Index (0.94) values indicating good fit. Also, al items indicated good factor loadings (range 0.25-0.94). Alpha values indicated that all subscales were internally consistent (range 0.64-0.92). CONCLUSIONS: Adult Self-Report was found to be a comprehensive tool showing a good model fit for Pakistani population.
