Abstract

Adolescence is a critical period marked by emotional and behavioral disorders due to various pressures, leading some teenagers to involved in juvenile delinquency or exhibited suicidal behavior. One of the contributing factors was the lack of optimism among individual. This research aims to test the validation of the optimism scale in adolescents. This research method is quantitative with Confirmatory Factor Analysis (CFA) technique to test the scale’s validity and reliability. The instrument used for analysis was the Optimism Scale from Seligman (2006), comprises three dimensions: permanence, pervasiveness, and personalization, totaling 48 items. Participants included 352 female public high school students, selected through purposive sampling. The initial tests revealed that 10 items had standardized loading estimates below 0.5, rendering them invalid and prompting their removal. The remaining 38 items were retested, and all demonstrated standardized loading estimates exceeding 0.5, confirming their validity. Additionally, the Composite Reliability (CR) value was above 0.7, and the Average Variance Extracted (AVE) exceeded 0.5, indicating reliability. Goodness-of-fit criteria showed strong results across five measures (Chi-square, Prob., RMSEA, CMIN/DF, and TLI), while one criterion indicated marginal fit (GFI). The conclusion is that the Optimism scale has proven to be valid and reliable for use among female public high school adolescents in Semarang.
