Development and Validation of Job Characteristics Scale for Pakistani Police Investigation Personnel

The objective of the study is to develop and validate the job characteristics scale for police investigation personnel based on the Job demand and Resource model (JDR).For this purpose, a purposive sampling technique was employed and police investigation personnel (N = 170) were taken from the police stations of all districts of Punjab Pakistan.The development and validation comprised two phases, which were further divided into many steps like domain specification, item generation, content validity, pilot testing, main data collection, item reduction, dimensionality assessment, and psychometric validation.48 items were revealed after the content validity index analysis (CVI) whereas factor analysis extracted 32 items of the Job Characteristics Scale comprising eight subscales.Confirmatory Factor Analysis (CFA) was carried out by using AMOS 21v, the value of (436) = 454.34,CFI = .99,GFI = .91,SRMR = .03,and RMESA = .01which indicated a good model fit for the scale.The value of composite reliability (CR) > 0.70 and the average variance extracted (AVE) > 0.50 showing very good construct reliability and convergent validity respectively.The divergent validity for the sub-domains was also assessed by MSV (Minimum-Shared Variance) analysis.The value obtained from the AVE for Political interference was 0.12, overload was 0.24, growth opportunity was 0.28, job variety was 0.25, organizational support was 0.28, feedback was 0.25, job autonomy was 0.17 and dealing with others was 0.12.The development and validation of a job characteristics scale for Pakistani police investigation personnel is crucial for enhancing our understanding of their work environment and for identifying areas for improvement that can promote their well-being and enhance their job performance.
