| Abstract: | Used a longitudinal design to test the main and stress-buffering effects of instrumentality on measures of trait anxiety, depression, and self-esteem. Ss were early (junior high school) and middle (senior high school) adolescent boys and girls. The hypothesis that instrumentality would be negatively related to psychological distress was supported by the cross-sectional and longitudinal regression analyses of every subgroup of Ss. The hypothesized stress-buffering effect of instrumentality was found in the cross-sectional and longitudinal analyses of senior high girls, specifically in the context of interpersonal negative events (relationship stress). The analyses for junior high girls revealed that instrumentality was beneficial only at a low level of relationship stress. There were no significant interaction effects in the regression analyses of boys. The findings suggest that, when experiencing relationship stress, instrumentality is helpful for middle adolescent girls but not for early adolescent girls. Therefore, future research on adolescents' life-stress adjustment should consider the roles of gender, age, personality, and type of life stress.
