Question: In the study by Jouriles and colleagues on adolescent relationship aggression, describe the three main constructs measured, how the researchers transformed their aggression measures to handle highly skewed distributions, and the resulting pattern of correlations among these constructs.

Sample answer: Jouriles and colleagues measured adolescents' physical aggression, psychological aggression, and psychological distress. To handle highly skewed distributions, they transformed the aggression measures into binary variables coded as 00 for 'did not occur' and 11 for 'did occur'. They found that physical aggression was moderately correlated with psychological aggression, which in turn was related to symptoms of psychological distress.

Key points:

  • The three target constructs measured were physical aggression, psychological aggression, and psychological distress.
  • Highly skewed distributions in aggression measures were handled by transforming them into dichotomous (binary) variables.
  • The aggression variables were coded as 00 for did not occur and 11 for did occur before computing correlations.
  • Physical aggression was moderately correlated with psychological aggression, which was related to symptoms of psychological distress.

Rubric: To receive full credit, the response must identify the three constructs (physical aggression, psychological aggression, and psychological distress), explain the dichotomization process including the specific coding values (00 and 11), and state the moderate correlation between physical and psychological aggression as well as the link between psychological aggression and distress.
