About

Introduction: Crohn's disease (CD) and obsessive-compulsive disorder (OCD) are two distinct medical conditions that affect millions of people worldwide. While numerous studies have explored anxiety and depression in CD, there is a notable lack of research about the link between OCD and CD. The aim of the study is to look for a relation between these seemingly unrelated conditions.

Methods: Patients with a diagnosis of Crohn's disease were given four different questionnaires in order to assess for the presence of obsessive-compulsive disorder, depression, and anxiety symptoms using the OCI-R score, DASS-21, PHQ-9, and GAD-7. The same questionnaires were used to assess healthy controls for similar symptoms.

Full description

This is an observational case-control study conducted at Jordan University Hospital. Using hospital medical records, patients with Crohn's disease who had been treated and followed up at the gastro-enterology and colorectal clinics were contacted to obtain consent to participate in the research and to explain its goals and the nature of the questionnaires used. Patients who agreed to participate were sent an online questionnaire to fill in. Healthy Controls with no medical illness or mental illness were invited to fill in the same questionnaire. The controls were relatives of patients attending the hospital for clinics not related to the gastrointestinal tract or psychiatry. Patients and controls with documented psychiatric illnesses were excluded.

The following psychological assessment tools were used:

The Obsessive-Compulsive Inventory-Revised (OCI-R) for obsessive-compulsive symptoms. It is composed of an 18-item self-report validated questionnaire that measures symptoms across 6 subscales including washing, checking, neutralizing, obsessing, ordering, and hoarding. The possible range of scores is 0-72.

The Depression Anxiety Stress Scales-21 (DASS-21) for overall emotional well-being. It is a set of three self-report scales to understand the degree of stress and distress, depressive and anxiety symptoms. The shortened version was used, which consists of 21 items and has been widely used for research and clinical purposes and is easy to administer.

The Patient Health Questionnaire-9 (PHQ-9), a nine-item depression scale of the patient health questionnaire, to assess depressive symptoms. The individual responses are interpreted as a score, with depression divided from no depression to severe depression.

The Generalized Anxiety Disorder-7 (GAD-7), a seven-item tool used to measure or assess anxiety symptoms and the severity of generalized anxiety disorder (GAD).

Data analysis:

The data was collected using Microsoft Forms and downloaded into Excel for coding and deidentification before being imported into the Statistical Package for Social Science (IBM SPSS Statistics for Windows, version 25, IBM Corp., Armonk, N.Y., USA) for analysis. The chi-square test was used to compare different categorical variables. The Mann-Whitney U test was used to compare non-categorical variables. The Kruskal-Wallis test was applied to test for significant differences between the scales.
