Background: There are insufficient data and measuring tools for parental perception of defecation and constipation in Thai children. The primary objective of this study was to develop a tool to measure parental perceptions towards defecation and constipation in children. The secondary objective was to identify parental understanding and misconceptions about these issues.
Methods: The authors developed a questionnaire in three domains: knowledge, attitude, and practice. Content validity was evaluated using the item-objective congruence index (IOC) by five experts. The reliability of the measure was assessed based on both internal consistency and test-retest reliability. Then, a descriptive cross-sectional survey was conducted on Thai parents at pediatric outpatient clinics and wards in Bhumibol Adulyadej Hospital.
Results: The authors developed a first draft questionnaire consisting of 31 items, which were categorized into three domains of knowledge, attitude, and practice. During expert validation, five items were disqualified. To assess the questionnaire's reliability, Cronbach's alpha value was calculated and found to be 0.229 for the original questionnaire. However, after removing irrelevant questions, Cronbach's alpha value increased to 0.511 for an 18-item questionnaire. The adjusted questionnaire demonstrated excellent test-retest reliability (Intraclass correlation coefficient, ICC = 0.91). The survey with 306 parents revealed parental misconceptions about the pathophysiology of stool withholding, stool soiling indicating constipation, toilet training after meals, and monitoring bowel movements.
Conclusion: The developed questionnaire helps to assess parental perception regarding defecation and constipation in Thai children. Based on the survey results, the authors suggest that parental education on these issues is still necessary.
