Adjustment Disorder and Suicidal Behaviours Presenting in the General Medical Setting: A Systematic Review

Abstract

Background: Adjustment disorder (AD) is a condition commonly encountered by clinicians in emergency departments and liaison psychiatry settings and has been frequently reported among patients presenting with suicidal behaviours. A number of previous studies have noted the strong association between suicidal ideation and behaviours, and AD. In this paper, we aimed to explore this relationship, by establishing the incidence of AD in patients who present with self-harm and suicidal ideation, and the rates of self-harm among patients with a diagnosis of AD. Methods: We conducted a review of the literature of well-established databases using specific key words then synthesised the results into a descriptive narrative as well as representing it in table form. Results: Sample sizes and study methods varied significantly across the review. A majority of studies were retrospective chart-based reviews, and only three used structured diagnostic instruments. A high prevalence of AD (ranging from 9.8 to 100%) was found, with self-poisoning representing the most common form of suicide attempt in the majority of studies. Interpersonal difficulties were the main precipitant in studies which examined this. Conclusions: This study suggests there is a strong association between AD and suicidal behaviours. Given the paucity of research in the area, there is a need to build the evidence base for effective treatment strategies.

Exploration of associations between deliberate self-poisoning and psychiatric disorders in rural Sri Lanka: A case-control study

“…However, DSP was more common among younger people-being aged less than 30 years was an independent risk factor for DSP. A higher prevalence of adjustment disorder in younger people with DSH has been reported in several low-income settings [12,[47][48][49]-but this was not observed in this study. Alcohol use disorders and depressive disorders were the significant correlates of the self-harm behaviour in adults who were older than 30 years of age.…”

“…It is considered a mild condition situated between normalcy and pathology (Fernández et al, 2012; O'Donnell et al, 2016). However, although the clinical symptoms of AjD are milder than in other anxiety and affective disorders, they are severe enough to cause important distress, functional impairment, low quality of life and even suicidal ideation and behaviour (Casey, Jabbar, O'Leary, & Doherty, 2015; Fegan & Doherty, 2019).…”
