<p>The objective of the study was to operationalize the perceived parental prosociality construct for adolescents. The sample consisted of 358 participants aged 12 to 18 years (M = 14.66; SD = 1.71) of both sexes. The discriminative power of the items, the internal consistency of the instrument, and various evidence of validity were analyzed. The results indicated that all the items were discriminative (p &lt;.000), the reliability satisfactory (FC = .91), and the CFA indicated an adequate adjustment, the correlation between the scale and adolescent prosocial behavior was positive and significant (r = .420; p &lt;.000).
