Mental disorders in female prisoners

OBJECTIVE: The objective of the study was to investigate the rates of mental disorder among women in prison in Victoria, and to compare with community rates. DESIGN: A midnight census of all women in prison in Victoria was undertaken. Respondents were interviewed with a version of the Composite International Diagnostic Interview (CIDI), an adapted version of the Personality Diagnostic Questionnaire (PDQ-4+) and a demographics questionnaire. MAIN OUTCOME MEASURES: Twelve-month prevalence rates of ICD-10 mental disorders including depressive disorders, anxiety disorders and drug-related disorders were examined. Prevalence of personality disorders was also investigated. RESULTS: Eighty-four per cent of the female prisoners interviewed met the criteria for a mental disorder (including substance harmful use/dependence) in the year prior to interview. This rate was reduced to 66% when drug-related disorders were excluded. Forty-three per cent of subjects were identified as cases on a personality disorder screener. For all disorders, (except obsessive-compulsive disorder and alcohol harmful use) women in prison had a significantly greater likelihood of having met the 12-month diagnostic criteria when compared to women in the community. The most prevalent disorders among the female prisoners were: drug use disorder (57%), major depression (44%), Posttraumatic stress disorder (36%), and personality disorders. Almost a quarter (24%) of respondents were identified as a 'case' on the psychosis screen. CONCLUSIONS: In the present study female prisoners had significantly higher rates of the mental disorders investigated (with the exceptions of OCD and alcohol harmful use) when compared with women in the community. The pattern of disorder found among female prisoners is consistent with the abuse literature, suggesting that histories of abuse among the prison population may account for part of the discrepancy. These results highlight the need for improved assessment and treatment resources to meet the demands of this population.     

Prevalence of psychiatric disorders in New Zealand prisons: a national study

OBJECTIVE: The paper describes the methodologies and results obtained on a large cohort of prison inmates in New Zealand who were screened for psychiatric disorder. METHOD: All women and remanded male inmates in New Zealand prisons, and a randomly selected cohort of 18% of sentenced male inmates were interviewed. Interviewers used the Composite International Diagnostic Interview - Automated to establish DSM-IV diagnoses, and the Personality Disorders Questionnaire to identify personality disorder. All prisons in New Zealand were visited. RESULTS: The results indicate markedly elevated prevalence rates for major mental disorder in the prison population when compared with community samples. This is especially the case for substance misuse, psychotic disorders, major depression, bipolar disorder, obsessive- compulsive disorder and posttraumatic stress disorder. Of particular concern is not only the increased prevalence rates for schizophrenia and related disorders but also the high level of comorbidity with substance misuse disorders demonstrated by this group. While 80.8% of inmates diagnosed with bipolar disorder were receiving psychiatric treatment in the prison, only 46.4% of depressed inmates and 37% of those suffering from psychosis were receiving treatment. Maori inmates were grossly overrepresented in the remand, female and male sentenced inmate population compared with the general population. CONCLUSIONS: A significant increase in provision of mental health services is required to cope with the high number of mentally ill inmates. The level of need demonstrated by this study requires a level of service provision that is quite beyond the capacity of current forensic psychiatry services, Department of Corrections Psychological Services or the prison nursing and medical officers. The elevated rates of common mental disorders argues for the use of improved psychiatric screening instruments, improved assessment and treatment capacities in the prison and an increased number of forensic psychiatric inpatient facilities to care for those psychotic inmates who are too unwell to be treated in the prison.     

Attention deficit/hyperactivity disorder in female offenders: prevalence,psychiatric comorbidity and psychosocial implications

Attention deficit-/hyperactivity disorder (ADHD) is associated with social maladaptation and delinquency in later life. This study was conducted to determine the prevalence of ADHD and comorbid conditions in female prison inmates. One hundred and ten adult female prison inmates of a German prison for women were investigated. SCID-I and -II interviews and standardized German instruments for the assessment of ADHD in adults (HASE) were used. The lifetime prevalence of ADHD was 24.5 and 10% for persisting ADHD according to DSM-IV criteria. A decline of the prevalence of persisting ADHD with age from 17.9% (age <25 years) to 10% (age 26–45 years) and 0% (age >45 years) was observed. Female prisoners with ADHD were younger at their first conviction as compared with females without ADHD and they showed longer incarceration periods in relation to age. The prevalence of other axis I disorders was high in both the ADHD and the non-ADHD female population, but significantly higher in ADHD females. Mean number of axis I diagnoses was 3.6 in females with ADHD and 2.3 in females without ADHD. No differences were found between females with and without ADHD regarding the prevalence of psychotic, affective, anxiety, somatization and posttraumatic disorders. Substance use disorders and in particular the use of stimulants were more frequent in females with ADHD as well as borderline personality disorder and eating disorders. The results suggest a high prevalence of ADHD in female prisoners that exceeds the prevalence estimates from epidemiological studies in general female populations. Moreover, it appears that ADHD is particularly frequent in adolescent and young adult female offenders and increases the risk for further psychiatric morbidity. The results indicate the need of adequate psychiatric support of female prison inmates including therapeutic programs for ADHD.     

The Christchurch prisons psychiatric epidemiology study: methodology and prevalence rates for psychiatric disorders

An investigation into psychiatric morbidity in the prisons in Christchurch, New Zealand is described. There are no previously published epidemiology studies concerning New Zealand prison inmates. A total of 225 inmates were approached to take part in the study representing a census of female inmates and remanded males and a randomly selected cohort of 125 sentenced males. Interviewers administered the Composite International Diagnostic Instrument – Automated (CIDI-A), a structured interview that generated both DSM-III-R and ICD 10 diagnoses. Interviews were completed on 183 inmates. Results reveal high lifetime and current prevalence rates for drug and alcohol abuse and dependence as well as high current and lifetime prevalence rates for affective disorders. Schizophrenia had a lifetime prevalence rate of 5% in the sentenced male population. Comparison with community epidemiological figures for psychiatric disorder reveal elevated lifetime and current prevalence rates among prison inmates for all major psychiatric diagnoses except generalized anxiety disorder. Implications for future treatment and service planning in forensic psychiatry are discussed with particular reference to a national epidemiology study of major psychiatric disorder in New Zealand prisons.

Health attitudes of psychiatric inpatients

Despite the high prevalence of medical illness in the mentally ill population, little is known about the health attitudes of patients with combined medical and psychiatric disorders. We compared the health attitudes of a group of inpatients with concomitant medical and psychiatric illness, a group of physically healthy psychiatric inpatients, and a group of normals. The instrument used was the Illness Attitude Scales, a self-rating scale designed to explore beliefs which can be responsible for hypochondriacal attitudes. A self-rating scale of psychological distress, the Symptom Questionnaire, was administered as well. Compared to normals, psychiatric patients displayed more hypochondriasis. There were no significant differences in psychological distress or health attitudes between patients with concomitant physical and psychiatric disorder and physically healthy psychiatric patients.     

Al Ain Community Psychiatric Survey. I. Prevalence and socio-demographic correlates

  Background: Psychiatric community stud- ies are essential for the planning and development of psychiatric services, as well as being helpful in examining the socio-demographic correlates of mental disorders in a given community. Few such studies have been carried out to date in the Arabian peninsula. This paper forms part of a multipurpose community psychiatric survey conducted in A1 Ain in the United Arab Emirates. The findings regarding lifetime prevalence and psychiatric morbidity are reported. Methods: A total of 1394 (n= 1394) adults systematically sampled from Al Ain community were assessed with a modified version of the Composite International Diagnostic Interview (CIDI) as well with other instruments: the new screening psychiatric instrument, Self-Reporting Questionnaire (SRQ-20), and the Structured Clinical Interview for DSM-IV Axis 1 disorders (SCID) screening module. Lifetime prevalence and 1-week prevalence rates of mental distress as measured by screening instruments were estimated as well as the lifetime prevalence rate of CIDI ICD-10 psychiatric disorders. The sensitivity of the CIDI interview to correctly pick up distressed subjects, as well as those who had undergone previous treatment for a psychiatric disorder, was also calculated. Associations between socio-demographic risk factors and ICD-10 psychiatric disorder as well as with mental distress were also examined by bivariate and multivariate analyses. Results: Overall lifetime prevalence of ICD-10 psychiatric disorder was found to be 8.2% (95% CI: 6.7–9.7), while the 1-week prevalence rate of mental distress as measured by the SRQ-20 was 15.6% (95% CI: 11.8–19.5) and the lifetime prevalence rate of mental distress as measured by the new screening instrument was 18.9% (95% CI: 11.5–25.9). The CIDI interview correctly picked up 42% of subjects who had received previous psychiatric treatment and 51% of the distressed. Mood disorders and anxiety (neurotic) disorders were more common in women and alcohol and substance use disorders were exclusively confined to men. Female sex, young age, quality of marital relationship, life events over past year, chronic life difficulties, physical illness, family history of psychiatric disorders and past history of psychiatric treatment were found to be significantly associated with ICD-10 psychiatric disorder. Multivariate analysis revealed that age, sex, exposure to chronic difficulties and past history of psychiatric treatment were the most significant predictors of ICD-10 psychiatric disorders, and exposure to chronic difficulties, past history of psychiatric treatment and educational attainment were the significant predictors of lifetime ever and current mental distress. Conclusion: The pattern and trend of psychiatric morbidity found in this survey is in line with those reported by other surveys that utilized similar assessment instruments. Differences in rates are explained by different methodologies used. Accepted: 3 October 2000     

Demographic factors, social problems and material amenities as predictors of psychological distress: a cross-sectional study in Karachi, Pakistan

Purpose

Previous research has shown high prevalence rates for stress and psychiatric morbidity in rural areas of Pakistan, but prevalence findings from urban areas vary widely (between 18 and 70 %). Many of these studies have focused on special populations and may not be representative of the general population in urban settings. The purpose of the present study was to ascertain prevalence and predictors of psychological distress in a representative sample of community dwelling adults from mid-low to low-income urban areas of Karachi, Pakistan.

Method

A cross-sectional survey was undertaken utilizing probability-based sampling from five mid-low to low-income communities of Karachi. Measures included the twelve-item Urdu version of general health questionnaire (GHQ-12), a demographic questionnaire, and questions about financial, health-related and family problems and about access to services and material amenities owned.

Results

Seventeen per cent of respondents (N = 1,188) were positive for psychological distress. More females were distressed than males and migrant groups had higher prevalence of distress as compared with natives of the city. Although other studies have shown low education or income to be associated with emotional distress and non-psychotic psychiatric morbidity, our study suggested that having limited income or education may make one more vulnerable to social problems that in turn may be associated with greater distress. An access to services and material amenities had a small but significant association with decreased distress.

Conclusion

The overall national prevalence rates may not reveal the influence of gender, region (rural v. urban) and migration on psychological distress. Further research is needed to address mental health of migrant groups in urban centers of Pakistan.     

Psychiatrie du sujet âgé en milieu pénitentiaire

ContextThe high prevalence of psychiatric disorders in prison and the aging of inmates should lead to the consideration of gerontopsychiatry in the prison environment.ObjectiveThis review aims to emphasize the clinical characteristics and associated comorbidities of elderly prisoners with psychiatric disorders. We examined the international literature in September 2013 and performed the literature search with PubMed electronic database using the following Mesh headings: “prisons”, “prisoners”, “geriatric psychiatry”, “geriatric assessment”, “geriatric nursing”.ResultsFourteen studies were retained by the literature search strategy and were included in the qualitative analysis. More than one out of two elderly prisoners (> 60 year-old) suffer from a psychiatric disorder. Major depressive disorder (MDD) is the first psychiatric disorder diagnosed among elderly prisoners, affecting 30 to 50% of them. Personality disorders are also very common demonstrating a prevalence of about 30%. Psychotic disorders concern 5% of the elderly prisoners and thus largely exceed the prevalence in the general population. Furthermore, stress events are frequent in prison and might precipitate or worsen psychiatric disorders. This review highlights the difficulties and complexities of care plans and management for the elderly in prison.ConclusionThe situation of elderly prisoners with psychiatric disorders is extremely worrying. In addition, both the aging of the population and the lengthening of incarcerations increase the number of elderly prisoners, widely exposed to psychiatric disorders, and thus will probably worsen these issues in the future.     

Survey of psychiatric morbidity in a semi-urban population in Sri Lanka

This paper reports a survey of psychiatric morbidity in a semiurban community (population 7,653) in Sri Lanka. The entire population was first screened by social workers using a standardized interview. Probable cases were then examined by psychiatrists. Each psychiatric disorder identified was rated on four different parameters of severity, and only those rating moderate or severe were labelled as cases. The socio-demographic characteristics of the cases and the population at risk, and the frequency and nature of psychiatric disorders are presented in Tables. The 6-month period prevalence for all psychiatric disorders was 45.5 per 1,000, with psychoses amounting to 6.9 (males 5.5; females 8.4) per 1,000, and neuroses to 25.2 (males 9.9; females 40.6) per 1,000. The large majority of disorders were chronic and had not received psychiatric treatment. The relevance of these surveys in the provision of psychiatric services in developing countries is discussed.     

Current somatoform disorders in Norway: prevalence,risk factors and comorbidity with anxiety,depression and musculoskeletal disorders

BACKGROUND: The future existence of somatoform disorders (SDs) has recently been debated. The objectives of this study were to investigate the prevalence of current SDs (defined as the presence of multisomatoform disorder [MSD] or somatoform disorders not otherwise specified [SDnos], without psychosocial impairment) and severe current SDs (MSD or SDnos with psychosocial impairment) in Norway. Differences in markers of severe current SDs, anxiety/depression and self-reported musculoskeletal disorders were explored. In addition, psychological distress and utilization of healthcare in subclasses (defined according to comorbidity with anxiety, depression and musculoskeletal disorders) of severe current SDs were examined. METHODS: We interviewed 1,247 respondents using the Composite International Diagnostic Interview (CIDI) in the Oslo-Lofoten general population survey in 2000-2001. Six-month prevalence rates (%) and 95% confidence intervals (CIs) for current SDs were investigated by gender and age. Risk factors of disorders, psychological distress, healthcare utilization and use of medication were explored using logistic regression analyses. RESULTS: The overall prevalence rate for severe current SDs was 10.2%. When psychosocial impairment was excluded as a criterion, the rate increased to 24.6%. Anxiety was strongly correlated with severe current SDs. Comorbidity of severe current SDs with anxiety/depression was 45%, and with musculoskeletal disorders, 43%. Analysis of healthcare utilization and use of medication showed that the presence of a comorbid psychiatric condition was more important than the presence of somatoform disorders alone. CONCLUSION: Somatoform symptoms alone (with no psychiatric comorbidity) should not be considered a psychiatric disorder.     

A study of lifetime prevalence of anxiety and depressive disorders in patients presenting with chest pain to emergency medicine

We studied the prevalence of anxiety and depressive disorders in patients with chest pain presenting to an emergency department. Majority of the patients had coronary artery disease (CAD). Twenty-three percent of patients with chest pain had a diagnosable psychiatric disorder according to ICD-10 research criteria. Anxiety and depressive disorders were equally distributed among patients with concomitant psychiatric syndrome. The level of psychological distress as measured on hospital anxiety and depression scale in patients of CAD with comorbid psychiatric syndrome was significantly more than patients with CAD alone and similar to non-CAD patients with psychiatric disorder. This finding is in agreement with an earlier study suggesting that the psychological distress seen in patients with CAD is related to the comorbid psychiatric condition and not to CAD.     

The Psychological Needs of Women Prisoners: Implications for Rehabilitation and Management

The rehabilitation and management of women offenders in prison are topics which continue to elicit concern, controversy and, often, disillusionment based on the failure of previous policies and initiatives. In this paper we argue rehabilitation and management should be based on the established needs of women prisoners and, in particular, on the Responsivity principle (adapting programs and methods to the gender-specific needs and requirements of women). Our review of the literature indicates major problems of psychological and psychiatric morbidity, including psychiatric disorder (especially posttraumatic stress disorder; PTSD), substance abuse, personality disorders, sexual/physical abuse and self-harm. The implications of such findings for good practice are discussed.     

Personality disorders in people with learning disabilities: a community survey

The prevalence of personality disorders has been determined by studies of both the general population and mental handicap hospitals. The present study attempts to determine the prevalence of personality disorders in a community sample and to check the implications for treatment A community sample of learning disability service users was surveyed by obtaining a rating from a good informant to establish demographic data, level of functioning and the nature of personality disorders, if any, using the ICD-I0 version of the Standardized Assessment of Personality (SAP). Fifty per cent of the sample had personality abnormalities, and 31% had sufficient impairment of the social and occupational domains and personal distress to warrant a diagnosis of personality disorder. These findings are compared with previous studies. Paranoid, schizoid, impulsive and dissocial personality abnormalities were seen to be associated with a high referral rate to psychiatric services and needed considerable therapeutic input The prevalence of personality abnormalities in community populations with a learning disability is high. The SAP is a useful instrument for screening. This sub-population makes significant demands on community psychiatric services.     

Mental health in prison populations. A review--with special emphasis on a study of Danish prisoners on remand

OBJECTIVE: To review the literature on mental health and psychiatric morbidity in prison populations and relate findings to a Danish study on remand prisoners. METHOD: The literature is reviewed and subdivided in the following section: validity of psychometrics in prison populations, prevalence of psychiatric disorders prior to imprisonment, incidence of psychiatric disorders during imprisonment, psychopathy related to psychiatric comorbidity, dependence syndromes with special emphasis on different administrations of heroin use (smoke vs. injection). The results are compared with a longitudinal Danish study on remand prisoners in either solitary confinement (SC) or non-SC. RESULTS: Many factors must be taken into consideration when dealing with prisoners and mental health, e.g. international differences, the prison setting, demographics and methodological issues. The prison populations in general are increasing worldwide. Psychometrics may perform differently in prison populations compared with general populations with the General Health Questionnaire-28 having a low validity in remand prisoners. Psychiatric morbidity including schizophrenia is higher and perhaps increasing in prison populations compared with general populations with dependence syndromes being the most frequent disorders. The early phase of imprisonment is a vulnerable period with a moderately high incidence of adjustment disorders and twice the incidence in SC compared with non-SC. Prevalence of psychopathy is lower in European than North American prisons. Medium to high scores of psychopathy is related to higher psychiatric comorbidity. Opioid dependence is the most frequent drug disorder with subjects using injection representing a more dysfunctional group than subjects using smoke administration. Many mentally ill prisoners remain undetected and undertreated. CONCLUSION: There is a growing population of mentally ill prisoners being insufficiently detected and treated.     

Nicotine,alcohol and drug dependence,and psychiatric comorbidity--results of a national household survey

There is a well-recognized relationship between substance use disorders and other psychiatric disorders. This relationship has been well documented in a range of population-based studies. This study aims to report on consumption patterns of and dependence on nicotine, alcohol, and non-prescribed drugs and to report on the levels of psychiatric morbidity in these groups. A national household study of psychiatric morbidity was conducted in England and Wales. Psychiatric assessment was based on the Clinical Interview Schedule-Revised (CIS-R). Measures of nicotine, alcohol and drug use and dependence were obtained. This paper compares the levels of psychiatric morbidity in the non-dependent and the nicotine-, alcohol- and drug-dependent cases. Twelve per cent of the non-dependent population were assessed as having any psychiatric disorder compared with 22% of the nicotine-dependent, 30% of the alcohol-dependent, and 45% of the drug-dependent population. There is a clear relationship between dependence on nicotine, alcohol, and drugs and other psychiatric morbidity.

Prevalence of attention deficit–/hyperactivity disorder (ADHD) and comorbid disorders in young male prison inmates*

OBJECTIVE: This study was performed to evaluate the prevalence of ADHD as well as comorbid conditions among young male prison inmates. METHOD: We investigated 129 prison inmates (mean age+/-SE: 19.2+/-2.0 years) and 54 healthy male control subjects (mean age+/-SE: 22.2+/-3.12 years) for the presence of adult ADHD using the Wender Utah Rating Scale (WURS), the Eysenck Impulsivity Questionnaire (EIQ), the diagnostic criteria for ADHD according to DSM-IV and ICD-10-research criteria and the Utah criteria for adult ADHD. In order to determine comorbid personality disorders we applied the International Personality Disorder Examination (IPDE). Externalization (ED) and Internalization Disorders (ID) were evaluated by means of the Achenbach Scales. Alcoholism (ALC) was examined via the Alcohol Use Disorder Test (AUDIT) and substance use disorder (SUD) has been investigated with the Structured Clinical Interview for DSM-IV (SCID). RESULTS: The overall prevalence of ADHD according to DSM-IV was 45%. The prevalence of disturbance of activity and attention (DAA) and hyperkinetic conduct disorder (HCD) via the ICD-10 research criteria was 21.7%. Sole DAA without any comorbid condition could be detected in one case. The most common diagnostic combinations were DAA/HCD and SUD/ALC (89% of all DAA/HCD cases). CONCLUSION: The prevalence of DAA/HCD or ADHD in young adult prison inmates is significantly elevated when compared to nondelinquent controls. Generally the population of young adult male prison inmates exhibits a considerable psychiatric morbidity. Of the total sample, 64% suffered from at least 2 disorders. Only 8.5% had no psychiatric diagnoses. This indicates the urgent need for more psychiatric expertise in young offender facilities.     

Prevalence of psychiatric disorders and suicide attempts in a prison population

A survey was conducted in which 180 randomly selected male prisoners ages 18 to 44 were interviewed using the Diagnostic Interview Schedule and other questionnaires. A comparison was made with 1,006 similarly aged male residents of Edmonton who were interviewed using the same instruments. Compared to the general population, prisoners were less likely to be married and were less well educated. There was a higher proportion of Native Indians in the prison sample and lower proportions of Oriental and other racial groups. Prisoners were twice as likely to have a lifetime psychiatric disorder compared with the general population, and all individual disorders investigated were more common in the prison population. Six month prevalence showed even greater rates compared with the general population, indicating recent symptoms. The number of individual disorders per prisoner was also higher than for the general population. Lifetime suicide attempts were seven times more frequent in prisoners than in the general population.     

The prevalence of personality disorder among UK primary care attenders

OBJECTIVE: To determine the prevalence rate of personality disorder among a consecutive sample of UK primary care attenders. Associations between a diagnosis of personality disorder, sociodemographic background and common mental disorder were examined. METHOD: Three hundred and three consecutive primary care attenders were examined for the presence of ICD-10 and DSM-4 personality disorders using an informant-based interview. RESULTS: Personality disorder was diagnosed in 24% (95% CI: 19-29) of the sample. Personality-disordered subjects were more likely to have psychiatric morbidity as indicated by GHQ-12, to report previous psychological morbidity, to be single and to attend the surgery on an emergency basis. 'Cluster B' personality disorders were particularly associated with psychiatric morbidity. CONCLUSION: There is a high prevalence rate of personality disorders among primary care attenders. These disorders are associated with the presence of common mental disorder and unplanned surgery attendance. Personality disorders may represent a significant source of burden in primary care.     

Psychological factors, pain attribution and medical morbidity in chest-pain patients with and without coronary artery disease

This cross-sectional psychiatric and cardiological study compared patients with and without coronary artery disease (CAD) with respect to psychiatric morbidity, psychological factors, pain characteristics, medical morbidity and the prevalence of coronary risk factors. The 199 participants had been referred to cardiological outpatient clinics for the investigation of chest pain and had no history of heart disease. Current panic disorder occurred significantly more often in non-CAD patients (41% vs. 22%). No significant differences were found for other psychiatric disorders and psychological variables. Non-CAD patients reported significantly longer histories of pain and a higher prevalence of atypical chest pain. In other respects, there were surprisingly few differences between the groups. High morbidity of both psychiatric disease (pain disorder, 19%; any current psychiatric disorder, 72%) and somatic conditions (musculoskeletal disease, 33%; dyspepsia, 23%) was found with no significant differences between the groups. In these patients, multifactorial complaints may explain chest pain in both patient groups. The physicians should attend to psychiatric disorders in non-CAD as well as in CAD patients.
