Second, rank-order change in children’s behavior problems was modeled by regressing mother-reported internalizing and externalizing problems from the most distal post-divorce assessment (age 15) onto mother-reported problems from the assessment immediately preceding the divorce (within 24 months of divorce for 98% of families). We also pulled one family at random from the propensity-matched never-divorced pool and used their data from the same time point as the family who experienced divorce. This allowed us to create a age-matched control group. Because teacher-reported outcomes were available only from kindergarten through sixth grade, these analyses of relative change were conducted only for mother-reported problems.
