More and more adolescents are seeking therapeutic intervention due to school-related anxious symptomatology. There is good evidence from the empirical literature that social support is related to anxiety, but does social support directly predict anxiety or is the relationship mediated by other variables? The present study of 110 college students found that an adolescent's motivational meaning system, conceptualized from Dweck's theory, mediated parental support and anxiety. Specifically, the lower parental support, the more Entity Thinking an adolescent is, and the more anxious that adolescent will be. Reasons, implications, and recommendations based on this finding are discussed.
