99. Prospective Associations between Positive Emotionality and Trajectories of Depression and Social Anxiety in Childhood and Adolescence: Moderation by Parent- and Peer- Stress

The present study used bivariate latent growth curve modeling (LGCM) to evaluate whether youth positive emotionality (PE) interacted with chronic parent- and peer- stress to predict social anxiety (SA) and depression symptom trajectories across 18 months. Participants included 543 youth (ages 8-16; 55.6% female). Parents reported on youth surgency at baseline, and chronic parent-child and peer stress were assessed 18 months later using the Youth Life Stress Interview. Youth reported on depression and SA symptoms every three months for 18 additional months (7 assessments). Depression and SA trajectories were characterized by quadratic growth. Bivariate LGCM predicting co-occurring SA and depression trajectories indicated that youth PE interacted with parent- (blinear=.11, bquad=-.02, p’s<.05) and peer- stress (blinear=.12, bquad=-.02, p’s<.05) to predict SA slopes in boys. Peer- (bint=.19, blinear=-.08, p’s<.05), but not parent- stress (b’s<|.05|), interacted with PE to predict SA trajectories in girls. For depression, parent-child stress associated with the intercept (b=2.24, p<.001), linear (b=-.46, p=.03) and quadratic (b=.08, p=.01) slope in boys; parent-child stress associated with the intercept (b=2.47, p<.001), linear (b=-.67, p=.001), and quadratic slope terms (b=.12, p<.001) in girls. In summary, youth PE interacts with interpersonal stress to predict trajectories of SA, whereas main effects of parent stress predict trajectories of depression, with different patterns of effects in boys and girls.
