Relationship between Self-Efficacy, Peer Pressure and Decision-Making among Adolescents

Adolescence is a critical developmental stage characterized by rapid psychological, cognitive, and social changes. During this period, peer influence becomes highly significant, often shaping adolescents’ attitudes, behaviors, and decision-making processes. At the same time, individual psychological factors such as self-efficacy play a crucial role in guiding behavior. The present study aimed to examine the relationship between self-efficacy, peer pressure, and decision-making among adolescents. A quantitative correlational research design was employed, and data were collected from 110 adolescents using standardized instruments including the General Self-Efficacy Scale (GSE), Peer Pressure Scale Questionnaire (PPSQ), and Child and Adolescent Participation in Decision Making Questionnaire (CAP-DMQ). Pearson’s correlation analysis revealed a significant negative relationship between self-efficacy and peer pressure (r = −.409, p < .001), a strong positive relationship between self-efficacy and decision-making (r = .744, p < .001), and a significant negative relationship between peer pressure and decision-making (r = −.528, p < .001). The findings suggest that adolescents with higher self-efficacy are better able to resist peer pressure and demonstrate stronger decision-making abilities.
