Mentoring programs may be contexts for building important intentional self-regulatory skills in adolescents. In this study, we provide data about the factor structure of new measures that assess youth intentional self-regulation (ISR) within such programs: the “GPS growth grids.” Using data from 409 mentor/youth dyads from 24 programs around the United States, we assess whether the resulting factor structure can be invariantly measured across mentor and mentee raters and three times of measurement. Results indicated that a single-factor structure best fit older and younger mentee age groups’ data. Older mentee and mentor data displayed measurement invariance across time and rater, while younger mentee and mentor data displayed invariance across time. Results also indicated differences in the factor correlations, means, and variances across rater and age group. These findings support using these measures for future longitudinal work assessing the role of youth, mentor, and program characteristics in promoting youth ISR skills.
