Abstract
This research developed a new test in Spanish to assess psychological maturity in adolescents, called PSYMAS and consisting of the subscales work orientation, identity, and autonomy. PSYMAS was administered to 669 students between 15 and 18 years. The results showed that the factorial structure of the test is acceptable, and that, in addition to subscale scores, total scores can be calculated to measure the overall psychological maturity of the subject. The convergent and discriminant validity of the test was also assessed based on a comparison with the Big Five personality factors. The results indicated that the test does in fact allow prediction of results in relation to personality traits.
