The impact of immigration detention on mental health: a systematic review.

BACKGROUND: The number of asylum seekers, refugees and internally displaced people worldwide has increased dramatically over the past 5 years. Many countries are continuing to resort to detaining asylum seekers and other migrants, despite concerns that this may be harmful. In light of the considerable body of recent research, this review aims to update and expand on a 2009 systematic review on the mental health consequences of detention on adult, adolescent and child immigration detainees, which found (on the basis on 9 studies) that there was consistent evidence that immigration detention had adverse effects on mental health. METHODS: Three databases were searched using key terms relating to immigration detention and mental health. Electronic searches were supplemented by reference screening. Studies were included if they were quantitative, included individuals detained for immigration purposes, reported on mental health problems and were published in peer-reviewed journals. Two reviewers independently screened papers for eligibility, and a further two reviewers completed quality appraisals for included studies. RESULTS: Twenty- six studies (21 of which were not included in the 2009 review) reporting on a total of 2099 participants were included in the review. Overall, these studies indicated that adults, adolescents and children experienced high levels of mental health problems. Anxiety, depression and post-traumatic stress disorder were most commonly reported both during and following detention. Higher symptom scores were found in detained compared to non-detained refugees. In addition (and more clearly than was evident in 2009), detention duration was positively associated with severity of mental symptoms. Greater trauma exposure prior to detention was also associated with symptom severity. CONCLUSIONS: The literature base reviewed in this paper consistently demonstrated severe mental health consequences amongst detainees across a wide range of settings and jurisdictions. There is a pressing need for the proper consideration of mental health and consequent risk of detention-related harm in decisions surrounding detention as well as for improved care for individuals within detention facilities. Recommendations based on these findings are presented, including increased focus on the identification of vulnerability and on minimising the duration of detention.

Mental health morbidity among people subject to immigration detention in the UK: a feasibility study.

AIMS: The UK has one of the largest systems of immigration detention in Europe.. Those detained include asylum-seekers and foreign national prisoners, groups with a higher prevalence of mental health vulnerabilities compared with the general population. In light of little published research on the mental health status of detainees in immigration removal centres (IRCs), the primary aim of this study was to explore whether it was feasible to conduct psychiatric research in such a setting. A secondary aim was to compare the mental health of those seeking asylum with the rest of the detainees. METHODS: Cross-sectional study with simple random sampling followed by opportunistic sampling. Exclusion criteria included inadequate knowledge of English and European Union nationality. Six validated tools were used to screen for mental health disorders including developmental disorders like Personality Disorder, Attention Deficit Hyperactivity Disorder (ADHD), Autistic Spectrum Disorder (ASD) and Intellectual Disability, as well as for needs assessment. These were the MINI v6, SAPAS, AQ-10, ASRS, LDSQ and CANFOR. Demographic data were obtained using a participant demographic sheet. Researchers were trained in the use of the screening battery and inter-rater reliability assessed by joint ratings. RESULTS: A total of 101 subjects were interviewed. Overall response rate was 39%. The most prevalent screened mental disorder was depression (52.5%), followed by personality disorder (34.7%) and post-traumatic stress disorder (20.8%). 21.8% were at moderate to high suicidal risk. 14.9 and 13.9% screened positive for ASD and ADHD, respectively. The greatest unmet needs were in the areas of intimate relationships (76.2%), psychological distress (72.3%) and sexual expression (71.3%). Overall presence of mental disorder was comparable with levels found in prisons. The numbers in each group were too small to carry out any further analysis. CONCLUSION: It is feasible to undertake a psychiatric morbidity survey in an IRC. Limitations of the study include potential selection bias, use of screening tools, use of single-site study, high refusal rates, the lack of interpreters and lack of women and children in study sample. Future studies should involve the in-reach team to recruit participants and should be run by a steering group consisting of clinicians from the IRC as well as academics.
