Polish adaptation of multisource assessment of children’s social competence

This study aimed to adapt the Multisource Assessment of Social Competence Scale for the Polish population. The population examined in the study included only Polish participants of European (Caucasian) ancestry. The tool is composed of two scales, Prosocial and Antisocial, and four subscales. For the purpose of adaptation, children’s social competence was evaluated based on their own and their parents’ perspective. The sample consisted of children aged 9–15 (n = 253) and their parents (n = 248), with boys and girls accounting for 43% (n = 109) and 57% (n = 144) of child participants, respectively. All the participants originated from the western-central Greater Poland Voivodeship. The data analyzed in this study were collected in 2019. Internal consistency of the subscales and correlation between them were measured using Cronbach’s Alpha reliability coefficient and Spearman's correlation coefficient, respectively. Confirmatory factor analysis was conducted for both groups (children and parents) in two-, three- and four-factor models. The confirmatory factor analysis for both groups (children and parents) attributed the four-factor model with the highest goodness-of-fit, fulfilling the criteria of a good-fitting model. The results show that the Multisource Assessment of Children’s Social Competence Scale is an appropriately adapted tool for the evaluation of the social competence of children in Poland, taking different rater perspectives into account.
