Latina/o adolescents may begin middle school with lower levels of life satisfaction, hope, and self-compassion. In the current study, a small-series (N = 5) single-case research design was implemented to evaluate the impact of a positive psychology group counseling experience to increase Latina/o adolescents' life satisfaction, hope, and self-compassion. Analysis of participants' scores on outcome measures yielded treatment effects indicating that the positive psychology group counseling experience may be effective for increasing hope, life satisfaction, and self-compassion. Given that the positive psychology approach was a promising approach for improving Latina/o adolescents' positive outcomes, implications for school counselors to integrate positive psychology into treatment processes are presented.
