There is growing recognition of the need to examine distinct forms of prosocial behaviors and to conduct research on prosocial behaviors among ethnic minorities. Middle school students (mean age=12.67 years; 54% girls; European American, n=290; Mexican American, n=152) completed a multidimensional measure of prosocial behavior and measures of parental monitoring, externalizing behaviors, and religiosity. Results yield supportive evidence that anonymous, dire, emotional, compliant, public, and altruism are different forms of prosocial behaviors. Moreover, the measure of prosocial behaviors shows measurement equivalence properties across ethnicity and gender. The discussion focuses on the multidimensional nature of prosocial behaviors and implications for future research on prosocial behaviors.
