Background

Inflammatory Bowel Disease (IBD) is a chronic relapsing-remitting inflammatory condition. Due to its long-term, multifaceted nature, patients will need to make many complex decisions during their treatment.

The Melbourne Decision Making Questionnaire (MDMQ) assesses the use of four decision-making styles. Vigilance is the only style considered adaptive, with a thorough, analytical approach. Buck-passing (avoiding responsibility), procrastination and hypervigilance (a hurried, anxious approach) are considered maladaptive.

This study aimed to assess the impact of psychological morbidity, health-related quality of life (HRQoL) and demographic/disease factors on decision-making in IBD.

Methods

People over the age of 16 with IBD completed the MDMQ. Psychological morbidity was assessed by the DASS-21 questionnaire, and HRQoL by the EQ-5D-3L/EQ-5D-Y. Demographic data included age, gender, ethnicity, Index of Multiple Deprivation quintile, educational level and employment status. Diagnosis, disease duration and age at diagnosis were also recorded.

Exploratory analysis of all variables against scores for each of the four decision-making styles was conducted. Significant results were used to perform multivariate analysis. All statistical analysis was performed using IBM SPSS Statistics software (v26).

Results

172 patients were studied (94 CD, 75 UC, 3 IBD-U, 68 (39.5%) male), median age 46.5 (16-83). Median MDMQ scores for vigilance, buck-passing, procrastination and hypervigilance were 10/12, 3/12, 2/10 and 3/10 respectively.

Multivariate analysis showed strong positive associations between psychological morbidity scores and all three maladaptive decision-making styles: buck-passing (F(1, 95)=12.512, p=0.001), procrastination (F(1, 115)=35.009, p<0.001) and hypervigilance (F(1, 114)=34.342, p<0.001). Age and duration of disease were not associated with decision making style.

Current employment and higher HRQoL scores were significantly associated with greater degrees of buck-passing (F(3,95)=5.100, p=0.003; and F(1, 95)=6.351, p=0.013 respectively).  A diagnosis of CD was associated with lower vigilance score (F(2, 133)=3.224, p=0.043).

Conclusion

People with IBD are likely to have an adaptive decision-making style, demonstrated by a high median vigilance score. However, psychological morbidity is associated with maladaptive decision-making – an important consideration for clinicians and in shared decision making. Further studies are required to determine whether interventions for psychological morbidity can improve maladaptive decision-making.
