Abstract:

There are conflicting data on peculiar negative emotional patterns in Irritable Bowel Syndrome subtypes.Our study was aimed to determine possible differences in depression, anxiety and anger in patients suffering from Irritable Bowel Syndromeconstipation, diarrhoea and mixed subtypes. The sample underwent a psychometric examination for the assessment of depression (Hamilton Rating Scale Depression), anxiety (Hamilton Rating Scale Anxiety), and anger (State-Trait Anger Expression Scale 2). Differences among groups were assessed using the Analysis of variance with Bonferroni post hoc comparisons, or the χ²-test if requested. Diarrhoea subtype constipation subtype were included in the study. The severity of depressive symptoms was “moderate” in patients with constipation subtype and “mild” in patients with diarrhoea mixed subtypes; no statistically significant differences were documented among subtypes. Severity of anxiety symptoms was “mild to moderate” in patients with constipation subtype (mean = 18.53 ± 7.7), and mild in patients with diarrhoea (mean = 13.35 ± 7.1) and mixed subtypes(mean = 13.25 ± 4.7); statistically significant differences among subgroups were found (Constipation vs Diarrhoea: p=0.004; Constipation vs. Regarding anger, significant differences among subgroups emerged at State Anger Feeling Angry and Anger In variables, both higher in constipation subtype group than in subtype group (State Anger Feeling Angry: p=0.002; Anger In: p=0.001). Patients with constipation subtypeconstitute a subgroup characterized by a discrete burden of negative emotions, mainly anxiety and anger.
