Psychological outcomes of a support intervention in mothers of children with ongoing health conditions: The parent-to-parent network

We compared depression, anxiety, anger, cognitive disturbance, and total scores on the Psychiatric Symptom Index (Ilfeld, 1976) for 365 mothers of 5-to-8 year-olds with diverse health conditions who were randomized either to an experimental (EG) or control (CG) group. EG mothers were offered a 12-month community-based support intervention; CG mothers received standard care. Posttest scores of EG and CG mothers did not differ significantly. Although intervention effects were not related to participation level or illness-related and sociodemographic factors, a significant interaction with stressful life events (SLE) was found. Among mothers reporting more than five SLE in the past year, posttest anxiety was lower in the EG than in the CG, but no difference was found between EG and CG mothers having less than five SLE. The intervention also acted as a moderator variable, with correlations of SLE and posttest depression, anxiety, and total symptoms significantly lower in the EG than CG. Possible explanations for these findings are discussed.
