The objective of this study was to analyze psychometric properties of the ARC INICO Self-Determination Scale (Verdugo et al., 2014), which consists of four subscales (Autonomy, Self-regulation, Empowerment and Self-realization), in high school students from private schools in Lima, Perú. The participating institutions were selected with non-probabilistic accidental or consecutive sampling where 311 students participated (63% male and 63% female) from first to fourth grade of secondary. To verify validity evidence based on relations to other variables the Perceived Self Efficacy in Academic Situations Scale or EAPESA was used (Dominguez, 2016). The data of the ARC INICO Scale was analyzed with a homogeneity analysis and afterwards with a Confirmatory Factor Analysis (CFA), finding the values of CFI = .89, RMSEA = .07 and Chi Square divided by degrees of freedom = 2.53, which confirm the original model. As well, evidence of reliability based on internal consistency was calculated using the coefficients Cronbach’s Alpha and McDonald’s Omega. Non-acceptable values (smaller than .70) were found for two subscales. The results from the EAPESA had low and moderate correlations (Spearman values between .29 and .49) with the subscales of the ARC INICO Scale, which was expected since both measure similar variables. In conclusion the ARC INICO Self-determination Scale is found partially valid and reliable, and it can be used only in the private schools that participated in this study in Lima, Perú.
