Adaptation and Psychometric Evaluation of Selected Scales from the Resilience Portfolio Questionnaire in School-Going Adolescents from Northern Chile

The Resilience Portfolio Model distinguishes regulatory, meaning-making and interpersonal strengths that help adolescents adapt to adversity, but no measure aligned with this model has been examined in Chile. This study adapted 13 scales (63 items) of the Resilience Portfolio Questionnaire and evaluated the internal structure, reliability and criterion relations of their scores in 889 adolescents aged 14–18 from northern Chile, 43.1% of whom reported a non-Chilean nationality. Items were purified in a calibration subsample (n = 445), and the retained specifications were tested without modification in a validation subsample (n = 444) and then re-estimated in the full sample. The theoretical structure was not reproduced, and three subdimensions were excluded. A bifactor exploratory structural equation model with one general and ten specific factors (41 items) was reproduced as the best-fitting specification in the validation subsample, although its fit was approximate and some misspecification remained (CFI = 0.934, TLI = 0.872, RMSEA = 0.063). It also fitted best in the full sample, which includes the calibration data (CFI = 0.969, TLI = 0.939, RMSEA = 0.041). In the full sample, the general factor was well defined (ωH = 0.78, H = 0.92), the specific reliability of the subscales ranged from 0.38 to 0.81, and the general factor had a correlation of −0.22 with psychological distress and 0.47 with life satisfaction. The results provide preliminary support for a short measure of ten resilient strengths that does not cover the full structure of the model and requires invariance testing across national groups.
