The objective of this study was to investigate the inter-relationship between psychosocial variables and their impact on symptom severity and quality of life (QoL) concerning abdominal bloating.
The study adopted a cross-sectional design with purposive sampling. Participants who consented and met the criteria for bloating based on the Rome IV classification completed designated questionnaires. Independent variables comprised health beliefs, intentions, health-promoting behaviors, social support, depression, and anxiety, while dependent variables included bloating severity (general and within 24 h) and QoL. Structural Equation Modeling (SEM) was conducted utilizing Mplus 8.0 to analyze the relationships between these factors.
A total of 323 participants, with a mean age of 27.69 years (SD = 11.50), predominantly females (64.7%), volunteered to participate in the study. The final SEM model exhibited good fit based on various indices (CFI = 0.922, SRMR = 0.064, RMSEA (95% CI) = 0.048 (0.041-0.054), -value = 0.714), with 15 significant path relationships identified. The model explained 12.0% of the variance in severity within 24 h, 6% in general severity, and 53.8% in QoL.
The findings underscore the significant influence of health beliefs, intentions, behaviors, social support, depression, and anxiety on symptom severity and QoL in individuals experiencing abdominal bloating.
本研究旨在探讨心理社会变量之间的相互关系及其对腹胀症状严重程度和生活质量（QoL）的影响。
本研究采用横断面设计和目的抽样法。根据罗马 IV 分类标准，对符合腹胀标准并同意参加研究的参与者完成指定的问卷。自变量包括健康信念、意图、健康促进行为、社会支持、抑郁和焦虑，而因变量包括腹胀严重程度（总体和 24 小时内）和 QoL。采用 Mplus 8.0 进行结构方程建模（SEM），以分析这些因素之间的关系。
共有 323 名参与者，平均年龄为 27.69 岁（SD = 11.50），主要为女性（64.7%），自愿参加研究。根据各种指标（CFI = 0.922，SRMR = 0.064，RMSEA（95% CI）= 0.048（0.041-0.054），- 值= 0.714），最终的 SEM 模型显示出良好的拟合度，有 15 条显著的路径关系。该模型解释了 24 小时内严重程度的 12.0%、总体严重程度的 6%和 QoL 的 53.8%的方差。
研究结果强调了健康信念、意图、行为、社会支持、抑郁和焦虑对经历腹胀的个体的症状严重程度和 QoL 的重大影响。
