اعتبار یابی و رواسازی مقیاس بهزیستی شخصی بزرگسالان (PWI-A)

The present research was aimed to investigate psychometric properties of personal wellbeing index (PWI-A) in clinical and nonclinical Iranian adult population. The study design was descriptive and study sample was composed non clinical group (292 university student) and clinical group (137 patients referred to family health clinic and 111 people as control group) that were selected using cluster sampling (nonclinical group) and goal oriented sampling (clinical group). To examine the convergent validity of the scale, the general health questionnaire (GHQ-28) and The World Health Organization’s WHOQOL-BREF quality of life were used. A coefficient Alpha of 0/89 obtained for the total scale, and coefficient Alpha of 0/84 and 0/86 obtained for each part of the scale, and also the test–retest correlation of 0/79 indicated a suitable reliability for the scale. Exploratory Factorial analysis for the scale showed one factor loading with predicting 59 percent of variance and confirmatory factor analysis showed moderate fitness of model. Correlation coefficients were moderate to high and suggested acceptable convergent validity with similar instruments. Finally the scale was able to differentiate quality of life between people suffering sexual dysfunction and non clinical group. In general, personal wellbeing index-adults (PWI-A) has good psychometric properties with respect methodological limitation of present study.
