Multidimensional motivation scale for community health workers: Psychometric properties and validation in a Turkish population

Aim The aim of this study was to adapt the Multidimensional Motivation Scale for Community Health Workers (MCHW) developed by Gottert et al. (2021) to the Turkish population and to test its validity of inferences and reliability of scores. Method The study was completed by 220 health personnel serving in the field of public health. Data were collected face-to-face using the Descriptive Information Form and Multidimensional Motivation Scale for Community Health Workers. Exploratory factor analysis (EFA) was used to identify the motivation factors and confirmatory factor analysis (CFA) was then used to certify the elementary factors produced by EFA using Comparative Fit Index (CFI), Tucker Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA) and the Standardized Root Mean Square Residual (SRMR). Results After EFA and CFA, a 21-item scale with 4 factors (Quality of supervision, feeling valued and competent, peer respect and support, compensation and workload) was identified with fit index values that were acceptable. Cronbach's α value was found between 0.78 and 0.92 for the sub-dimensions of the study and α = 0.92 for the whole scale (>0.70). In the EFA with 21 items, the Kaiser–Meyer–Olkin value was 0.901, and the Barlett test result was 3385.63 ( p < .000). In the test-retest analysis, no significant difference (p > 0.05) was found between the total mean scores, while the reliability correlation was found to be within the appropriate range (0.55–0.85). The scale demonstrated good test-retest reliability (ICC = 0.762, p < 0.01), indicating temporal consistency. CFA confirmed the results, showing acceptable model fit: CFI = 0.929, TLI = 0.916, RMSEA = 0.071, and SRMR = 0.079. Conclusions The results of the study show that the scale is a valid and reliable tool that can be used to determine the motivation of health personnel working in public health organizations in Turkish society.
