- Objective To examine the associations of daily hassles with the somatic and psychological health of Crohn's disease (CD) patients. Method A cross-sectional study of 400 self-selected adult CD patients was performed with completion of demographic, medical, and psychosocial questionnaires: economic status; Patient Harvey-Bradshaw Index of disease activity; Daily Hassles Scale (DHS); Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and Short-Form Health Survey (SF-36 Physical and Mental Health) quality of life measures; Brief Symptom Inventory of psychological stress with summary Global Severity Index (GSI); Family Assessment Device; and List of Threatening Life Experiences. Analyses included correlations, regressions, and Sobel test statistic. Results The patients were aged 38.7 ± 14.1 years, 61% female and 67% working. The Patient Harvey-Bradshaw Index was 5.52 ± 4.87. The DHS was 88.0 ± 23.2, similar in men and women, higher in smokers, and increased with greater disease activity (p < .001). The most commonly reported hassles were time, social, and work. DHS had significant negative correlations with age, disease duration, and economic status and positive correlations with GSI, SF-36, and SIBDQ. An increased Daily Hassles score was associated with reduced SIBDQ (p < .001) and SF-36 Mental Health (p < .001) and increased GSI (p < .001) and Patient Harvey-Bradshaw Index (p < .001). This effect of DHS on Patient Harvey-Bradshaw Index was mediated by GSI (Sobel t = 6.09, p < 0.001). Conclusion Daily hassles in CD patients are shown for the first time to be associated with increased psychological stress and disease activity and reduced quality of life and lower economic status. This has psychotherapeutic implications.
