Abstract

Background: Adolescence can bring emotional and behavioral disorders, leading some teenagers to involved in juvenile delinquency or exhibited suicidal behavior. One of the contributing factors was the lack of optimism among individual. Purpose: This research aims to examine the validity of the optimism scale among adolescent. Method: A quantitative approach using Confirmatory Factor Analysis (CFA) was employed to evaluate the scale’s validity and reliability. The instrument used was the Optimism Scale from Seligman (2006), which has three dimensions (permanence, pervasiveness, personalization) and 48 items. The study involved 352 female public high school students selected through purposive sampling. Findings: 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. 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. Implication: This valid and reliable optimism scale can support further studies on female public high school adolescents in Semarang.
