Insights
Cognitive behavior therapy (CBT) and intensive medical care (IMC) equally reduced functional abdominal pain in children. Both treatments improved secondary outcomes, suggesting comparable effectiveness for pediatric functional abdominal pain.
Area of Science:
- Pediatric Gastroenterology
- Child Psychology
- Clinical Trials
Background:
- Functional abdominal pain (FAP) is a common condition in children, significantly impacting their quality of life.
- Current treatment approaches for pediatric FAP vary, with limited evidence comparing psychological interventions to standard medical care.
Purpose of the Study:
- To compare the effectiveness of a 6-session protocolized cognitive behavior therapy (CBT) against 6 visits of intensive medical care (IMC) for treating pediatric functional abdominal pain (FAP).
- To evaluate the impact of CBT versus IMC on abdominal pain levels, other gastrointestinal symptoms, functional disability, somatic complaints, anxiety, depression, and quality of life in children with FAP.
Main Methods:
- A randomized controlled trial involving 104 children aged 7 to 18 with FAP.
- Participants were randomized to receive either 6 sessions of CBT (delivered by master's students) or 6 visits of IMC (delivered by pediatricians/gastroenterologists).
- Primary outcomes included self-reported abdominal pain via questionnaires and diaries, with assessments at pre-treatment, post-treatment, and 6- and 12-month follow-ups. Secondary outcomes encompassed a range of physical and psychological symptoms.
Main Results:
- Both CBT and IMC led to significant reductions in abdominal pain (P < .001).
- No significant differences in treatment effectiveness were observed between CBT and IMC at the 12-month follow-up for primary or secondary outcomes.
- At 1 year, symptom improvement or recovery rates were similar: 60% for CBT vs. 56.4% for IMC (questionnaire data) and 65.8% for CBT vs. 62.8% for IMC (diary data).
Conclusions:
- Cognitive behavior therapy (CBT) demonstrates equal effectiveness to intensive medical care (IMC) in alleviating functional abdominal pain in children.
- The findings suggest that psychological interventions like CBT can be a viable alternative or adjunct to standard medical management for pediatric FAP.
- Further research is warranted to elucidate the specific mechanisms through which CBT exerts its therapeutic effects in pediatric functional abdominal pain.
Objective:
This randomized controlled trial investigated the effectiveness of a 6-session protocolized cognitive behavior therapy (CBT) compared with 6 visits to a pediatrician (intensive medical care; IMC) for the treatment of pediatric functional abdominal pain (FAP).
Methods:
One hundred four children aged 7 to 18 were randomized to CBT or IMC. CBT was delivered primarily by trained master's degree students in psychology; IMC was delivered by pediatricians or pediatric gastroenterologists. Assessments were performed pretreatment, posttreatment, and at 6- and 12-month follow-up. Primary outcomes were level of abdominal pain (AP) as reported on questionnaires and diaries. Secondary outcomes were other gastrointestinal complaints, functional disability, other somatic complaints, anxiety, depression, and quality of life.
Results:
Both CBT and IMC resulted in a significant decrease in AP (P < .001), but no significant difference was found between the treatments in their effectiveness (P > .05 for all end points). According to the questionnaire-derived data, 1 year after treatment, 60% of children that received CBT had significantly improved or recovered, versus 56.4% of children receiving IMC, which did not significantly differ (P = .47). These percentages were 65.8% versus 62.8% according to the diary-derived data, which also did not significantly differ (P = .14). Additionally, nearly all secondary outcomes improved after treatment.
Conclusions:
CBT was equally effective as IMC in reducing AP in children with FAP. More research into the specific working mechanisms of CBT for pediatric FAP is needed.
