Purpose: To evaluate post-treatment efficacy of DARWeb (online psychosocial intervention for children with functional abdominal pain) using a randomized clinical trial design and combining quantitative and qualitative data.
Patients and methods: Twenty-five families with children with FAP in the experimental group (EG: accessed to DARWeb) and 36 in the control group (CG: wait-list) were compared. Children and parents completed measures of abdominal pain severity (primary outcome), quality of life, and satisfaction. Moreover, children completed measures of depression, functional disability, catastrophizing and coping strategies; parents completed measures about parental responses to their children’s pain. Families also answered open questions and were interviewed.
Results: A higher percentage of children in the EG achieved a significant clinical change in abdominal pain severity from the parents’ perspective (28% in the EG vs 8.33% in the CG). There was a significantly greater reduction in pain frequency in the EG compared to the CG (both from the children’s and parents’ perspectives) from mixed repeated-measures analyses of variance (there was not a significant interaction in total scores of pain severity). A higher percentage of children in the EG improved in quality of life and depression compared to the CG (results from mixed methods repeated-measures analyses of variances were not significant). However, there were no differences for disability, pain catastrophizing or the coping strategies assessed from the children’s perspective; neither from the parents’ assessment of quality of life. There were significant interactions for parents’ solicitousness responses and promotion of well behaviors in the expected directions. Families were quite satisfied with the intervention, and the qualitative results confirmed an improvement in pain and having learned important coping strategies.
Conclusion: Our results support the efficacy of our intervention, but future studies are needed with different profiles of initial severity of the pain problem, longer follow-ups, and other conditions.
