Short Answer

Suppose you are applying the data transformation method from the Jouriles et al. study to a new dataset. Participant X reports 0 incidents of physical aggression and 4 incidents of psychological aggression. Participant Y reports 2 incidents of physical aggression and 0 incidents of psychological aggression. State the binary codes (00 or 11) for both participants on both physical and psychological aggression variables.

Question: Suppose you are applying the data transformation method from the Jouriles et al. study to a new dataset. Participant X reports 0 incidents of physical aggression and 4 incidents of psychological aggression. Participant Y reports 2 incidents of physical aggression and 0 incidents of psychological aggression. State the binary codes (00 or 11) for both participants on both physical and psychological aggression variables.

Sample answer: Participant X would be coded as 00 for physical aggression and 11 for psychological aggression. Participant Y would be coded as 11 for physical aggression and 00 for psychological aggression.

Key points:

  • Participant X is coded as 00 for physical aggression and 11 for psychological aggression.
  • Participant Y is coded as 11 for physical aggression and 00 for psychological aggression.
  • The coding rule assigns 00 to non-occurrence (zero events) and 11 to occurrence (one or more events).

Feedback: According to the transformation rule used by Jouriles et al., any frequency of aggression greater than zero is coded as 11 (did occur), while a frequency of zero is coded as 00 (did not occur). Therefore, Participant X is coded as 00 (physical) and 11 (psychological), and Participant Y is coded as 11 (physical) and 00 (psychological).
