VALIDAÇÃO PSICOMÉTRICA DA ESCALA DE HABILIDADES ASSERTIVAS PARA ADOLESCENTES

Abstract

Assertiveness is a primordial social skill in the socialization process, it allows the adolescent to adapt to different contexts, in addition to favoring the maintenance of other important skills during this phase, such as civility, self-control and emotional expressiveness. The aim of this study is to present the validation process of the Assertive Skills Scale for Adolescents (AHAA). 476 adolescents, aged between 11 and 19, participated. The application was carried out in person at public and private institutions. Data from these participants were equally organized into two different databases. In the first bank, item quality analysis (item response theory - IRT) and exploratory factor analysis (EFA) were performed; with the second, a confirmatory factor analysis (CFA) was performed. The TRI results indicated that not all items had appropriate discrimination and difficulty values. Therefore, it was decided to discard items with low psychometric quality for subsequent data analyses. In the exploratory factor analysis (EFA) and in the confirmatory factor analysis (AFC), good adjustment indices were observed, indicating the extraction of only one factor underlying the scale structure. Internal consistency values showed an adequate degree of reliability of the measure, with Cronbach's Alpha and McDonald's Omega values greater than 0.70. Thus, the present study demonstrated satisfactory psychometric properties and promises to be a useful tool to measure assertive social skills in adolescents.
