The Conventional Activities of Friends Scale will be used to measure prosocial activities of friends. This scale includes 8 questions concerning the number of friends that engaged in prosocial activities. These behaviors range from obeying school rules to participating in religious activities. High scores indicate that most friends engage in these conventional behaviors, and the lowest scores reflect the complete absence of any friends involved in these prosocial and traditional activities. Scale scores are summed for each subject, thereby reflecting the overall degree of exposure to peers engaged in these conventional behaviors. This scale will be used as an indicator of prosocial activities in testing Hypothesis 2d.
