Yield and Efficiency of Mental Health Screening: A Comparison of Screening Protocols at Intake to Prison.

ABSTRACT:

Background

The value of screening for mental illness has increasingly been questioned in low prevalence settings due to high false positive rates. However, since false positive rates are related to prevalence, screening may be more effective in higher prevalence settings, including correctional institutions. We compared the yield (i.e. newly detected cases) and efficiency (i.e. false positives) of five screening protocols to detect mental illness in prisons against the use of mental health history taking (the prior approach to detecting mental illness).

Methods and findings

We estimated the accuracy of the six approaches to detect an Axis I disorder among a sample of 467 newly admitted male inmates (83.1% participation rate). Mental health history taking identified only 41.0% (95% CI 32.1, 50.6) of all inmates with mental illness. Screening protocols identified between 61.9 and 85.7% of all cases, but referred between 2 and 3 additional individuals who did not have a mental illness for every additional case detected compared to the mental health history taking approach. In low prevalence settings (i.e. 10% or less) the screening protocols would have had between 4.6 and 16.2 false positives per true positive.

Conclusions

While screening may not be practical in low prevalence settings, it may be beneficial in jails and prisons where the prevalence of mental illness is higher. Further consideration of the context in which screening is being implemented, and of the impacts of policies and clinical practices on the benefits and harms of screening is needed to determine the effectiveness of screening in these settings.

Project description:Incarceration is definitively linked to poor health, and upon release from prison, many individuals experience difficulty in maintaining good health. Given the complexity of the reentry process, one's health status, both in and out of prison, likely influences additional aspects of reentry, such as abstaining from crime or adhering to parole terms. The purpose of this study is to determine whether in-prison physical and mental health, as well as changes to an individual's health upon release from prison, are related to the likelihood of recidivating. We employ the Serious and Violent Reentry Initiative (SVORI) data, a multi-state sample of formerly incarcerated males who are followed from prison to release into the community and interviewed about a number of post-prison release issues, including health. We use hierarchical logistic and multinomial regressions, where survey waves are nested within people, to assess if in-prison physical and mental health and post-release changes to health are associated with recidivism in two ways: general re-incarceration and re-incarceration due to either a technical violation of parole or a new conviction. With right-censoring due to recidivism or "failure," our final sample size is 2180 person-periods (i.e., waves) nested within 871 respondents. We find that better physical health, both in-prison and changes in health post-release, is related to a higher likelihood of recidivating. Better mental health, both in-prison and changes to mental health post-release, is related to a decrease in the likelihood of recidivating. Individuals with poor mental health in-prison who make significant improvements after release see the largest reduction in their odds of recidivating. Finally, the combination of better mental health in-prison and increases in mental health post-release is associated with reductions in the likelihood of re-offending for both technical violations and new convictions. In sum, in-prison health continues to influence individuals after prison and is associated with their odds of recidivating, thus contributing to the churning of individuals through the prison system.

Project description:BackgroundCommon mental health problems are prevalent in prison and the quality of prison health care provision for prisoners with mental health problems has been a focus of critical scrutiny. Currently, health policy aims to align and integrate prison health services and practices with those of the National Health Service (NHS). Medication management is a key aspect of treatment for patients with a mental health problem. The medication practices of patients and staff are therefore a key marker of the extent to which the health practices in prison settings equate with those of the NHS. The research reported here considers the influences on medication management during the early stages of custody and the impact it has on prisoners.MethodsThe study employed a qualitative design incorporating semi-structured interviews with 39 prisoners and 71 staff at 4 prisons. Participant observation was carried out in key internal prison locations relevant to the management of vulnerable prisoners to support and inform the interview process. Thematic analysis of the interview data and interpretation of the observational field-notes were undertaken manually. Emergent themes included the impact that delays, changes to or the removal of medication have on prisoners on entry to prison, and the reasons that such events take place.Results and discussionInmates accounts suggested that psychotropic medication was found a key and valued form of support for people with mental health problems entering custody. Existing regimes of medication and the autonomy to self-medicate established in the community are disrupted and curtailed by the dominant practices and prison routines for the taking of prescribed medication. The continuity of mental health care is undermined by the removal or alteration of existing medication practice and changes on entry to prison which exacerbate prisoners' anxiety and sense of helplessness. Prisoners with a dual diagnosis are likely to be doubly vulnerable because of inconsistencies in substance withdrawal management.ConclusionChanges to medication management which accompany entry to prison appear to contribute to poor relationships with prison health staff, disrupts established self-medication practices, discourages patients from taking greater responsibility for their own conditions and detrimentally affects the mental health of many prisoners at a time when they are most vulnerable. Such practices are likely to inhibit the integration and normalisation of mental health management protocols in prison as compared with those operating in the wider community and may hinder progress towards improving the standard of mental health care available to prisoners suffering from mental disorder.

Project description:BackgroundAntenatal depression and anxiety disorders are highly prevalent in low and middle-income countries. Screening of pregnant women in primary care antenatal settings provides an opportunity for entry to care, but data are needed on the performance of different screening tools. We compared five widely-used questionnaires in a sample of pregnant women in urban South Africa.MethodPregnant women attending a primary care antenatal clinic were administered five tools by trained research assistants: the Edinburgh Postnatal Depression Scale (EPDS), the Patient Health Questionnaire (PHQ-9), the Kessler Psychological Distress scale (K10) and a shortened 6-item version (K6), the Whooley questions and the two-item Generalised Anxiety Disorder scale (GAD-2). Following this, a registered mental health counsellor administered the MINI Plus, a structured clinical diagnostic interview. The Area Under the Curve (AUC) from Receiver Operator Characteristic curve analysis was used to summarise screening test performance and Cronbach's α used to assess internal consistency.ResultsOf 376 participants, 32% were diagnosed with either MDE and/or anxiety disorders. All five questionnaires demonstrated moderate to high performance (AUC = 0.78-0.85). The EPDS was the best performing instrument for detecting MDE and the K10 and K6 for anxiety disorder. For MDE and/or anxiety disorders, the EPDS had the highest AUC (0.83). Of the short instruments, the K10 (AUC = 0.85) and the K6 (AUC = 0.85) performed the best, with the K6 showing good balance between sensitivity (74%) and specificity (85%) and a good positive predictive value (70%). The Whooley questions (AUC = 0.81) were the best performing ultra-short instrument. Internal consistency ranged from good to acceptable (α = 0.89-0.71). However, the PPV of the questionnaires compared with the diagnostic interview, ranged from 54% to 71% at the optimal cut-off scores.ConclusionsUniversal screening for case identification of antenatal depression and anxiety disorders in low-resource settings can be conducted with a number of commonly used screening instruments. Short and ultra-short screening instruments such as the K6 and the Whooley questions may be feasible and acceptable for use in these settings.
