Development and evaluation of a screening tool for identifying prisoners with severe mental illness

Feasibility testing of a peer support programme for prisoners with common mental disorders and substance use

BACKGROUND

The prevalence of mental disorders and substance use among prisoners is high. Convicted prisoners of 'good behaviour' can be part of a peer support system in prisons.

AIM

To evaluate the feasibility of a peer support programme for prisoners with common mental disorders and substance use in prison.

METHOD

The study used a mixed method research design, with a quasi-experimental approach (single group pre-post without control). It was conducted in two phases: Phase I. Thirty-five peers/convicted prisoners were recruited through advertisements on the prisoners' community radio station. Volunteers with good behaviour reports were given training over 5 days to recognise mental and substance use disorders and provide basic peer support in prison; their attitudes and knowledge were tested before and after the training.

PHASE II

Feasibility of the peer support programme was tested by (i) recording the number of cases identified and referred, (ii) pre- and post-evaluation of well-being, coping, and symptom severity of those supported and (iii) evaluating qualitatively the experience of the peer supporters and service users.

RESULTS

Thirty-five peer supporters identified 49 cases over 3 months. These cases showed significant improvement in well-being (Z -1.962; p < 0.050) and reduction in symptom severity (Z -1.913; 0.056). There was a significant improvement in the peers supporters' self-esteem from pre- to post-training (t -3.31; p < 0.002), improvement in their benevolence (t -4.37; p < 0.001) and a significant reduction in their negative attitudes to mental illness (Z -3.518; p < 0.001). A thematic model of peer support encompassed self-experienced benefits for the peer supporter, wider recognition of peer supporters in the prison, challenges to this kind of support, experience of training and visions for future work.

CONCLUSION

The peer support programme was experienced positively by the peer-supporters and supported. Common mental disorders, substance use and suicidality were recognised and appropriately referred. A full-scale evaluation of this promising programme is warranted.

A systematic review of the effectiveness and cost-effectiveness of peer-based interventions to maintain and improve offender health in prison settings

Background

Offender health is deemed a priority issue by the Department of Health. Peer support is an established feature of prison life in England and Wales; however, more needs to be known about the effectiveness of peer-based interventions to maintain and improve health in prison settings.

Objectives

The study aimed to synthesise the evidence on peer-based interventions in prison settings by carrying out a systematic review and holding an expert symposium. Review questions were (1) what are the effects of peer-based interventions on prisoner health and the determinants of prisoner health?, (2) what are the positive and negative impacts on health services within prison settings of delivering peer-based interventions?, (3) how do the effects of peer-based approaches compare with those of professionally led approaches? and (4) what are the costs and cost-effectiveness of peer-based interventions in prison settings?

Data sources

For the systematic review, 20 electronic databases including MEDLINE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature and EMBASE were searched from 1985. Grey literature and relevant websites were also searched. To supplement the review findings 58 delegates, representing a variety of organisations, attended an expert symposium, which provided contextual information.

Review methods

Two reviewers independently selected studies using the following inclusion criteria: population – prisoners resident in prisons and young offender institutions; intervention – peer-based interventions; comparators: review questions 3 and 4 compared peer-led and professionally led approaches; outcomes – prisoner health or determinants of health, organisational/process outcomes or views of prison populations; study design: quantitative, qualitative and mixed-methods evaluations. Two reviewers extracted data and assessed validity using piloted electronic forms and validity assessment criteria based on published checklists. Results from quantitative studies were combined using narrative summary and meta-analysis when appropriate; results from qualitative studies were combined using thematic synthesis.

Results

A total of 15,320 potentially relevant papers were identified of which 57 studies were included in the effectiveness review and one study was included in the cost-effectiveness review; most were of poor methodological quality. A typology of peer-based interventions was developed. Evidence suggested that peer education interventions are effective at reducing risky behaviours and that peer support services provide an acceptable source of help within the prison environment and have a positive effect on recipients; the strongest evidence came from the Listener scheme. Consistent evidence from many predominantly qualitative studies suggested that being a peer deliverer was associated with positive effects across all intervention types. There was limited evidence about recruitment of peer deliverers. Recurring themes were the importance of prison managerial and staff support for schemes to operate successfully, and risk management. There was little evidence on the cost-effectiveness of peer-based interventions. An economic model, developed from the results of the effectiveness review, although based on data of variable quality and a number of assumptions, showed the cost-effectiveness of peer-led over professionally led education in prison for the prevention of human immunodeficiency virus (HIV) infection.

Limitations

The 58 included studies were, on the whole, of poor methodological quality.

Conclusions

There is consistent evidence from a large number of studies that being a peer worker is associated with positive health. Peer support services can also provide an acceptable source of help within the prison environment and can have a positive effect on recipients. This was confirmed by expert evidence. Research into cost-effectiveness is sparse but a limited HIV-specific economic model, although based on a number of assumptions and evidence of variable quality, showed that peer interventions were cost-effective compared with professionally led interventions. Well-designed intervention studies are needed to provide robust evidence including assessing outcomes for the target population, economic analysis of cost-effectiveness and impacts on prison health services. More research is needed to examine issues of reach, utilisation and acceptability from the perspective of recipients and those who choose not to receive peer support.

When and why should mentally ill prisoners be transferred to secure hospitals: a proposed algorithm

For reasons well known and researched in detail, worldwide prevalence rates for mental disorders are much higher in prison populations than in general, not only for sentenced prisoners but also for prisoners on remand, asylum seekers on warrant for deportation and others. Moreover, the proportion of imprisoned individuals is rising in most countries. Therefore forensic psychiatry must deal not only with the typically young criminal population, vulnerable to mental illness due to social stress and at an age when rates of schizophrenia, suicide, drug abuse and most personality disorders are highest, but also with an increasingly older population with age-related diseases such as dementia. While treatment standards for these mental disorders are largely published and accepted, and scientific evidence as to screening prisoners for mental illness is growing, where to treat them is dependent on considerations for public safety and local conditions such as national legislation, special regulations and the availability of treatment facilities (e.g., in prisons, in special medical wards within prisons or in secure hospitals). While from a medical point of view a mentally ill prisoner should be treated in a hospital, the ultimate decision must consider these different issues. In this article the authors propose an algorithm comprising screening procedures for mental health and a treatment chain for mentally ill prisoners based on treatment facilities in prison, medical safety, human rights, ethics, and the availability of services at this interface between prison and medicine.

Health screening in police custody

BACKGROUND

There have been few previous studies on the health needs of police detainees. London's Metropolitan Police Service (MPS) uses health screening procedures which have not yet been evaluated. The objective of this study is to determine the extent of health problems and 'mental vulnerability' in detainees in police custody, and the efficacy of current health screening procedures.

METHODS

Custody records from five London Boroughs were reviewed. Prevalence data for health problems and mental vulnerability was obtained from the anonymised records of 307 detainees who were referred to the Forensic Medical Examiner (FME). Data were analysed for the identification of physical and psychiatric morbidity.

RESULTS

Injuries, epilepsy and asthma were the most common physical health problems noted. Drug and alcohol issues were also frequently encountered along with depression and self-harming behaviour and suicidal ideation. Morbidity was lower than that reported in other, interview based studies. Less than 2% of detainees were thought to require an Appropriate Adult to be present during police interview.

CONCLUSIONS

A significant amount of health morbidity is present among detainees in police custody. Our findings suggest that current police screening procedures detect only a proportion of this. Further research is warranted to evaluate the effectiveness of health screening in police custody.
