Turkish Adaptation of Self-Efficacy for Alternatives to Aggression Scale

Abstract

The aim of this study was to adapt the Self-Efficacy for Alternatives to Aggression Scale (SEAAS; Miller-Johnson, Sullivan, Simon, & MVPP, 2004) to Turkish culture. The SEAAS measures the adolescents' self-efficacy on anger control and resolving conflict in a nonaggressive way. The sample of the study consisted of 566 secondary school students enrolled in seven different public schools in Ankara. The mean age of the participants was 13.09 (SD= .95). The psychometric properties of the scale were analyzed by means of internal consistency, split-half and confirmatory factor analysis (CFA). The Cronbach's alpha coefficient was found to be .79 and split-half reliability was found to be .70. The results of the fit indices (RMSEA = .08, GFI = .97, AGFI = .93, CFI = .96 and TLI = .95) showed that model has a good fit. In addition, the relationship between the SEAAS and Physical Aggression Scale was examined for criterion validity and a significant negative relationship (r = -.29, p< .01) was found. Analyses indicated that the SEAAS had a satisfactory level of reliability and validity in Turkish adolescent sample.
