Abstract

The current cross-sectional research was performed to verify the measurement soundness of the Personal Growth Initiative Scale-II (PGIS-II) regarding reliability, validity, and gender invariance in an Iranian sample.
In an online survey, 1,453 students (50.8% girls, mean_age = 15.48, SD = 0.97) were recruited from several high schools located in Tehran to complete the Persian version of PGIS-II, Youth Self-Report (YSR) of internalizing and externalizing behavior problems, and demographic characteristics.
The original 4-factor structure of PGIS-II demonstrated the best fit in the Confirmatory factor analysis and was invariant across gender. Reliability estimates of this factorial model, including corrected item-total correlation, inter-item correlations, Cronbach's alpha, Theta, and Omega were good to excellent (e.g., α = 0.86-0.95). Discriminant validity was upheld via the moderate correlation among PGIS-II's subscales, and through the acceptable levels of average variance extracted. The concurrent validity of the Persian version of PGIS-II and its subscales was supported by their moderate negative correlations with internalizing and externalizing behavioral problems (r = -0.20 to -0.42) and their moderate positive correlations with educational performance (r = 0.21-0.34). Gender differences emerged, such that boys scored higher on PGIS-II and the subscale of using resources.
Overall, the PGIS-II seems suitable for application in the Persian context to capture personal growth initiative. Clinicians and school counselors should devote attention to the personal growth initiative as a key mechanism to prevent adolescents' behavior problems and improve academic performance.
