Personality assessment in children with abdominal pain predominant functional gastrointestinal diseases

Abstract

BACKGROUND AND AIMS: Chronic abdominal pain is a commonly associated with psychological problems. This study aimed to evaluate the personality traits in teenagers with abdominal pain predominant functional gastrointestinal diseases (AP-FGD). METHODS: Data regarding gastrointestinal symptoms, and personality assessment were collected from teenagers aged 13–18 years from 5 randomly selected schools in Ampare district of Sri Lanka. AP-FGD were diagnosed using Rome III criteria. Translated and validated personality assessment questionnaire (PAQ) was used to assess the total personality maladjustment score and personality domains; namely hostility and aggression, dependency, lack of self esteem, lack of self adequacy, emotional instability, emotional unresponsiveness, and negative world view. RESULTS AND DISCUSSION: A total of 1697 children were recruited [males 778 (45.9%), mean age 15.1 years and SD 1.66 years]. AP-FGD were seen in 202 (11.9%) teenagers. They were compared with 1051 normal children. When the cutoff value for Sri Lankan children (89) was used, 66.3% of with AP-FGD and 42.5% controls had PAQ scores within that of psychological maladjustment (p < 0.001). When the international normative value of 105 was used, these percentages were 27.2% and 11.2% respectively (p < 0.0001). Subgroup analysis revealed similar differences in all 4 subtypes of AP-FGD compared to controls (p < 0.05). Children with AP-FGD had significant higher mean scores for all personality domains compared to controls except for dependence (p < 0.05). Children with irritable bowel syndrome and abdominal migraine also showed similar results (p < 0.05). Apart from dependency and emotional instability children with functional dyspepsia were noted to have higher mean scores for all other personality domains (p < 0.05). In addition, children with functional abdominal pain had signifi cantly higher mean scores for all personality domains except dependency and negative world view (p < 0.05). CONCLUSIONS: Psychological maladjustment is significantly more common in all four subtypes of AP-FGD.
