Some studies have shown that character strengths positively predicted optimal performance and well-being in Western, educated, industrialized, rich, and democratic (WEIRD) societies which may hold limited generalizability to individuals in non-WEIRD contexts. This prospective study examined the association of selected interpersonal character strengths (i.e., fairness, teamwork, leadership, forgiveness, and kindness) with life satisfaction, teacher-reported academic engagement, Mathematics achievement, English achievement, and overall academic achievement among Filipino high school students enrolled in a public high school in the Philippines ( M age = 14.33). There was a 2-month interval between Time 1 and Time 2 data collection. Results indicate that whereas fairness and kindness demonstrated stronger magnitudes of associations with subsequent life satisfaction, academic engagement, and achievement, teamwork and forgiveness had positive and moderate intensity of relationships to such outcomes. Compared to other interpersonal strengths, leadership showed weaker correlations with life satisfaction and achievement outcomes. Results allude to the benefits associated with interpersonal positive virtues in a non-WEIRD context.
