Source: (-0001) Conflict Resolution Quareterly. 16(3):253-267.Increasing client participation in victim-offender mediation is a/undamental challenge facing practitioners. A large database from an established victim- offender reconciliation program (VORP) was used to examine the predictors of client participation in victim-offender mediation. Hypotheses were tested using logistic regression analysis. Results show that client participation varies with the type of offense and the amount of time elapsed between the offense and the case referral. The results suggest that VORPs can maximize client participation by emphasizing rapid processing of cases involving property offenses and delayed processing of those involving personal offenses. Additional predictors of participation are discussed. (author's abstract).
