Abnormal personality traits in children with aerophagia

Abstract

OBJECTIVE: The main objective of this study is to study the personality types in children with aerophagia. METHODS: A cross sectional survey was conducted in 8 randomly selected schools in 4 randomly selected provinces Sri Lanka. From each school, all children aged 13-18 years were selected after obtaining written consent from parents, school administration and provincial education office. Assent was obtained from all children recruited. Date were collected using a self-administered questionnaire administered under examination setting to ensure confidentiality and privacy. Questionnaire contained previously translated and validated Rome III questionnaire for functional gastrointestinal diseases (self-administered form for children above 10 years) and childhood personality assessment questionnaire. Trained research assistants were present during filling the questionnaire to provide assistance and to verify doubts. Aerophagia was defined using the Rome III criteria. Severities of individual symptoms were recorded in 100 mm visual analogue scale. RESULTS: A total of 1069 questionnaires were distributed and all of them were returned and included in analysis [males 508 (47.5%), mean age 15.3 years, SD 1.8 years years]. One hundred and thirty six (12.7%) fulfilled Rome III criteria for aerophagia and 933 children without aerophagia were considered as controls. Nineteen (13.8%) children with aerophagia and 71 (7.6%) controls had personality scores above the international cut-off value (105) for abnormal personality (p = 0.01). Children with aerophagia had significantly higher scores for different personality traits than controls; including hostility and aggression (13.2 vs. 12.2 in controls, p = 0.006), negative self-esteem (11.0 vs. 9.9, p < 0.0001), negative self-adequacy (10.6 vs. 9.6, p = 0.001), emotional unresponsiveness (10.5 vs. 9.6, p < 0.0001), emotional instability (16.9 vs. 15.7, p < 0.001), negative world view (10.9 vs. 10.1, p = 0.02) and total personality score (92.1 vs. 87.7, p = 001). In children with aerophagia, scores obtained for severity of bloating correlated with scores obtained for hostility and aggression (r = 0.22, p = 0.02). CONCLUSIONS: Children with aerophagia has abnormal personality traits and this fact may at least partly responsible for development and perpetuation of symptoms in them.
