This study evaluates the efficacy of the Children of Divorce Intervention Program (CODIP), a preventive intervention based on social support and coping skills, for 4th-6th grade urban children of divorce. Structure and content of the 14 group sessions were tailored to the developmental level and sociocultural make-up of the target sample. Pre-post comparisons of demographically matched groups of 57 CODIP participants, 38 non-program divorce controls and 93 children from non-divorced families revealed improvements on parent, child and group leader measures of adjustment. Limitations of the study and directions for future research are discussed.
