Gender differences in patients with schizophrenia and substance abuse

Victimization of People With Severe Mental Illness Outside and Within the Mental Health Care System: Results on Prevalence and Risk Factors From a Multicenter Study

We performed a cross-sectional study using a self-reporting survey to assess lifetime violent and non-violent victimization in people with severe mental illness experienced both inside (i.e., any service providing mental health care such as psychiatric hospitals, psychosocial rehabilitative programs, or outpatient care) and outside (i.e., in the personal life of the participants) of the mental health care system. We recruited 170 participants from 20 community mental health facilities. We built logistic regression models to assess potential risk factors for victimization inside the mental health care system. Outside of the mental health care system, the most commonly reported events were theft (n=93, 54.7%), physical violence without use of a weapon (n=87, 51.2%), and sexual harassment (n=82, 50.6%). Within the mental health care system, most commonly reported incidents were theft (n=68, 40.0%), sexual assault (n=18, 10.6%), and physical violence (n=47, 27.7%) by other patients or staff. Significant risk factors for specific victimization events inside the mental health care system were psychotic disorder, victimization in childhood and youth, female gender, number of hospitalizations, and duration of illness. Findings call for increased attention to victimization of people with severe mental illness, especially within the mental health care system as such victimization events may severely impact patients' trajectories.

The role of substance use and adult sexual assault severity in the course of schizophrenia: An epidemiological catchment study of sexual assault victims

BACKGROUND

Childhood trauma increases the risk of schizophrenia, yet the role of adult sexual assault in the course of schizophrenia is unknown. This study aims to examine the associations between substance use and sexual assault severity characteristics with the course of schizophrenia among adult sexual assault victims using an epidemiologic study design.

METHODS

Sexual assault data on all individuals received from 2000 to 2010 (N = 2147) at the Center for Care of Sexual Assault Victims at Wolfson Medical Center, the largest medical center for sexual assault victims in the country, were merged with the Israel National Psychiatric Case Registry, that consisted of lifetime psychiatric hospitalizations of schizophrenia (birth to 6 years post-assault). The associations between substance use and adult sexual assault severity characteristics with hospitalizations were quantified using recurrent events Cox modeling.

RESULTS

Schizophrenia with sexual assault survivors occurred in 117 persons. Cox modeling showed that recurrent psychiatric hospitalizations were associated with younger age, sexual assault at older age, previous diagnosis of psychosis, and drug use shortly before or during the assault. Other assault characteristics (number of assailants, means of subdual, penetration type, perpetrator violence, physical injury of the victim) and immediacy of seeking help had a null association with the course of psychiatric hospitalization. These results replicated in two sensitivity analyses.

CONCLUSIONS

Substance use among victims of sexual assault was associated with an exacerbated course of schizophrenia, pointing to a possibly modifiable risk factor that should be targeted in prevention, assessment, treatment formulation and implementation.

Cigarette Smoking among Economically Disadvantaged African-American Older Adults in South Los Angeles: Gender Differences

The current study aims to explore gender differences in the risk of cigarette smoking among African-American (AA) older adults who live in economically disadvantaged urban areas of southern Los Angeles. This cross-sectional study enrolled 576 older AA adults (age range between 65 and 96 years) who were residing in Service Planning Area 6 (SPA 6), one of the most economically challenged areas in southern Los Angeles. All participants had cardiometabolic disease (CMD). Data were collected using structured face-to-face interviews. Demographic factors (age and gender), socioeconomic status (educational attainment and financial difficulty), health (number of comorbid medical conditions and depressive symptoms), and health behaviors (current alcohol drinking and current smoking) were measured. Logistic regressions were used to analyze the data without and with interaction terms between gender and current drinking, depressive symptoms, and financial difficulty. AA men reported more smoking than AA women (25.3% versus 9.3%; p < 0.05). Drinking showed a stronger association with smoking for AA men than AA women. Depressive symptoms, however, showed stronger effects on smoking for AA women than AA men. Gender did not interact with financial difficulty with regard to current smoking. As AA older men and women differ in psychological and behavioral determinants of cigarette smoking, gender-specific smoking cessation interventions for AA older adults who live in economically deprived urban areas may be more successful than interventions and programs that do not consider gender differences in determinants of smoking. Gender-tailored smoking cessation programs that address drinking for AA men and depression for AA women may help reduce the burden of smoking in AA older adults in economically disadvantaged urban areas. Given the non-random sampling, there is a need for replication of these findings in future studies.

Needs of women patients with mental illness

Women patients suffer from a range of mental disorders similar to those that men may experience. However, there are some striking differences in the prevalence of specific disorders, and in their presentation and management. Some mental illnesses only occur in women. It seems that women patients may have a different experience of treatment, a consequence of differences in their needs and also of the way that health professionals perceive those needs. These differences are embedded in the wider cultural milieu in which we live. There are particular issues for women patients in relation to, for example, childhood sexual abuse, rape and domestic violence. At present, tools to measure needs of individual patients are generally not gender specific.

Violent victimization and health service utilization in a forensic psychiatric context: a comparison between offenders with mental disorders and matched controls

BACKGROUND

Offenders with mental disorders constitute a particularly exposed group in society, with high rates of morbidity, mortality, and social deprivation. Often thought of primarily as perpetrators, these individuals may also be subjected to violence. Previous research indicates that violent victimization during lifespan is a risk factor for violent perpetration among psychiatric patients, but victimization studies on the group of offenders with mental disorders are scarce. Health services are pivotal to this group, but although most individuals do utilize these services, their vulnerability seems to remain. This study aimed at exploring the rates of victimization and health service utilization, including perceptions of unmet health care needs, among offenders with mental disorders.

METHODS

Two hundred detainees undergoing a forensic psychiatric evaluation in Stockholm were asked about violent victimization and health service utilization. Each detainee was compared with three controls from the general population, matched regarding age, sex, and occupation.

RESULTS

Victimization during the past year was reported by 52.3% of the detainees and 11.1% of the controls, with a corresponding risk ratio of 8.2. Health service utilization during the past three months was reported by 47.7 and 23.7%, respectively (risk ratio 2.0); and unmet health care needs by 42.2 and 16.7%, respectively (risk ratio 3.4). There was no distinct association between victimization and health service utilization among detainees.

CONCLUSIONS

Offenders with mental disorders are at great risk of being victimized, and they experience impediments to receiving requisite health care. A possible way to reduce victimization and improve health service utilization may be to establish interdisciplinary yet specialized health centers with outreach teams but without complicated referral procedures.

Trauma exposure and PTSD in women with schizophrenia and coexisting substance use disorders: comparisons to women with severe depression and substance use disorders

The present study compared rates of trauma exposure and PTSD among three groups of women at high trauma risk: those with substance use disorders (SUD) and schizophrenia (n=42), those with SUD and severe, nonpsychotic depression (n=38), and those with SUD and no other DSM-IV Axis I condition (n=37). We hypothesized that exposure to traumatic stressors and current diagnosis of PTSD would be more common in women with schizophrenia and SUD, when compared to the other two groups. Results indicate that women with schizophrenia and SUD had a more extensive trauma history than women with SUD only, and were also more likely to have PTSD. Women with schizophrenia had a fourfold greater likelihood of meeting criteria for current PTSD than were women with severe, nonpsychotic depression when potential confounds of age, race, education, severity of trauma history, and childhood trauma exposure were controlled. These results lend support to the possibility that women with psychosis have an elevated vulnerability to PTSD symptomology when exposed to life stressors that is distinct from the vulnerability associated with coexisting nonpsychotic SMI. The psychological sequelae of trauma are substantial and should be addressed in women seeking treatment for schizophrenia and problematic substance use.

Sociodemographic and Clinical Characteristics of Victimized Versus Non-Victimized Patients with Schizophrenia: An Egyptian Study

Persons with mental disorders living in the community are liable for victimization and are considered as a high-risk group. Objective of this study was to explore the sociodemographic variables and clinical characteristics related to victimization of patients with schizophrenia in comparison to their nonvictimized counterparts. One hundred patients were recruited from the inpatient wards and outpatient clinics of the Institute of Psychiatry, Ain Shams University. They were subjected to Structured Clinical Interview for DSM-IV Axis I diagnosis (Clinical Version); Positive and Negative Syndrome Scale (PANSS); Global Assessment of Functioning (GAF); Clinical Global Impression (CGI); designed extensive questionnaire to elicit demographic data; inquiry about drug compliance and Victimization Questionnaire. Results show that 70 patients of the studied sample were non-victimized and 30 patients were victimized. Victimized patients were significantly younger, living mainly in urban areas, had less frequent history of bullying at school. There were exposed significantly to higher frequency of family domestic violence and childhood abuse. They scored higher for all subscales and in total PANSS scores and they were less compliant on medication than did their non-victimized counterparts. Until now studies of victimization of mentally ill did not draw the attention of researchers and clinicians in Arab world. This study proves that victimization is not uncommon among patients with schizophrenia; Clinicians should include assessment for victimization of their patients as a routine work. The current study provides preliminary data for clinicians and policy makers to consider strategies to protect patients with various mental illnesses from being victimized.

Violent victimization of adult patients with severe mental illness: a systematic review

The aims of this paper are to review data on the prevalence and correlates of violent victimization of persons with severe mental illness, to critically evaluate the literature, and to explore possible approaches for future research. PubMed/MEDLINE and PsycINFO databases were searched using several terms related to severe mental illness in successive combinations with terms describing victimization. The searches identified 34 studies. Nine epidemiological studies indicate that patients with severe mental illness are more likely to be violently victimized than other community members. Young age, comorbid substance use, and homelessness are risk factors for victimization. Victimized patients are more likely to engage in violent behavior than other members of the community. Violent victimization of persons with severe mental illness has long-term adverse consequences for the course of their illness, and further impairs the quality of lives of patients and their families. Victimization of persons with severe mental illness is a serious medical and social problem. Prevention and management of victimization should become a part of routine clinical care for patients with severe mental illness.

Sex differences in first-admission psychiatric inpatients with and without a comorbid substance use disorder

OBJECTIVES

We assessed sex differences in a sample of first-admission psychiatric inpatients with and without comorbid substance use disorder (SUD) to identify possible risk factors and targets for sex-tailored treatment interventions.

METHODS

A retrospective study of first admissions to the University Psychiatry Ward, "Maggiore della Carità" Hospital, Novara, Italy, between 2003 and 2012 was accomplished. The clinical charts of patients with (N = 362) and without comorbid SUD (N = 1111) were reviewed.

RESULTS

Differences in employment, educational, and marital statuses were found between male and female psychiatric patients with and without comorbid SUD. Having a degree was a protective factor for males, whereas it was a risk factor for females. Being divorced and having family problems were both risk factors for comorbidity in females. Regarding the diagnosis, results overlapped in males and females, and both affective and other disorders were risk factors for a comorbid SUD.

CONCLUSIONS

A significant difference between male and female psychiatric patients with a comorbid SUD was the males' overall poorer psychosocial functioning. Marital status and family problems were risk factors for comorbid SUD in females. Both males and females showed various pathways of access to and choices of substances and, eventually, experienced different impacts on their lives. Hospitalization might help to set up a targeted intervention for patients with comorbidity, while accounting for sex differences. With respect to males, a treatment approach focused on the substance alone might help improve their functioning; females might have a greater benefit from a treatment approach focused on distress, family problems, and relational issues.

Prevalence and correlates of criminal victimization among new admissions to outpatient mental health services in Hawaii

Adults with serious mental illness (SMI) experience criminal victimization at rates higher than the general population whether they reside in the community or correctional settings. This study examines the past-six month prevalence and correlates of criminal victimization among a large community sample (N = 2,209) of consumers with SMI newly admitted to outpatient mental health services during 2005 through 2008. A cross-sectional design was used with self-report and clinical data collected from administrative records. Victimization was determined by responses to direct questions about experiences in the previous 6 months with respect to victimization of a non-violent and/or violent crime. Socio-demographic, clinical and criminal correlates of victimization were abstracted from a quality of life survey and clinical assessment interview conducted at admission. Overall, 25.4 % of consumers reported being a victim of any crime (violent or non-violent) in the past 6 months, with 20.3 % reporting non-violent and 12.3 % violent victimization. The risk of victimization was elevated for those who were female, White, not taking atypical psychotropic medication, not feeling safe in their living arrangement, and were arrested or homeless in the six-months prior to engaging in mental health outpatient treatment. Policy and practice implications of these findings are discussed.

A UK population-based study of the relationship between mental disorder and victimisation

PURPOSE

To establish the prevalence of victimisation in a UK population-based sample and to investigate the association between mental disorder and victimisation in both cross-sectional and prospective manner, whilst adjusting for potential confounds.

METHODS

Data from the National Child Development Study (NCDS) were used to examine criminal victimisation, violent victimisation, and mental disorder at age 46 yerars, and also to measure history of mental disorder, when cohort members were aged 23, 33 and 42 years. Variables considered to be potential confounders or mediators of the association, including socio-economic status, family income, financial strain, education, housing ownership status, heavy drinking and gender, all measured at age 46 years, were considered in multivariate analyses.

RESULTS

The prevalence of criminal victimisation amongst cohort members in the 12 months preceding interview was 15%; 2.2% of the participants reported experiencing violent victimisation in the past year. Mental disorder at age 46 was significantly associated with criminal and violent victimisation, even after adjusting for potential confounds. A prior history of mental disorder was found to be a robust predictor of criminal and violent victimisation.

CONCLUSIONS

This study provides evidence that those with a mental disorder are at elevated risk of victimisation, including violent victimisation. That such an association might reflect an underlying causal relationship is further supported by the confirmation that the association holds true when mental disorder is measured well before the assessment of victimisation risk, and that it persists despite adjustment for a number of potential confounding factors.

Effect of cannabis use on the course of schizophrenia in male patients: a prospective cohort study

BACKGROUND

Findings on the impact of cannabis use on the course of schizophrenia are inconsistent and not conclusive.

AIMS

To study the effect of cannabis use on the course of schizophrenia taking into account the effects of the quantity of cannabis use and important confounders.

METHODS

Prospective cohort study with assessments of symptoms, confounders and hospitalizations at baseline, 6 month and 12 month follow up.

RESULTS

In a representative cohort of 145 male patients with schizophrenia, 68 (46.9%) used cannabis. Mean age at onset of schizophrenia in cannabis using patients was significantly lower than in non-cannabis using patients. No other cross-sectional demographic or clinical differences were observed between users and non-users. In a series of longitudinal analyses, cannabis use was not associated with differences in psychopathology, but relapse in terms of the number of hospitalizations was significantly higher in cannabis using patients compared to non-cannabis using patients.

CONCLUSIONS

Patients with schizophrenia using cannabis are more frequently hospitalized than non-cannabis using patients but do not differ with respect to psychopathology. Possible explanations for these findings are discussed.

Predictors of initiation and engagement in substance abuse treatment among individuals with co-occurring serious mental illness and substance use disorders

Research has documented the significant challenges of engaging individuals with comorbid serious mental illness (SMI) and substance use disorders (SUDs) in substance abuse treatment. To date it is unclear which factors predict treatment initiation and engagement in this group of individuals with SUDs. In this study we conducted two analyses using data from a randomized trial of substance abuse treatment in outpatients with SMI: the first examining predictors (collected during screening) of completing an initial intake assessment and the second examining predictors (collected during the intake assessment) of becoming engaged in treatment. Results indicated that males and those with schizophrenia spectrum diagnoses were less likely to complete the intake assessment. Participants who reported more positive feelings about their family were more likely to engage in substance abuse treatment. Participants who were recently arrested were less likely to engage in treatment. Those who met criteria for current drug dependence were less likely to engage in treatment. Overall, these findings are a useful step in determining factors that predict substance abuse treatment initiation and engagement in individuals with SMI and SUDs.

Violent victimization of psychiatric patients: a Swedish case-control study

OBJECTIVES

To report the rate of violent victimization of psychiatric patients 1 year before interview and to examine the relative rate in comparison to the general population.

METHOD

Cases were recruited from two public psychiatric hospitals in Stockholm County (n = 390). The controls comprised gender- and age-matched people interviewed in an annual national survey of living conditions (n = 1,170).

RESULTS

Twenty percent of the patients had been victimized during the preceding year. The relative rate was six times higher than that of the controls. Women appeared to be most vulnerable with a tenfold risk increase.

CONCLUSIONS

The findings stress that psychiatric patients are vulnerable to other people's violent behaviour.

Gender differences in substance use, consequences, motivation to change, and treatment seeking in people with serious mental illness

Gender differences in patterns and consequences of substance use, treatment-seeking, and motivation to change were examined in two samples of people with serious mental illness (SMI) and comorbid substance use disorders (SUDs): a community sample not currently seeking substance abuse treatment (N = 175) and a treatment-seeking sample (N = 137). In both groups, women and men demonstrated more similarities in the pattern and severity of their substance use than differences. However, treatment-seeking women showed greater readiness to change their substance use. Mental health problems and traumatic experiences may prompt people with SMI and SUD to enter substance abuse treatment, regardless of gender.

Differential substance abuse patterns distribute according to gender in heroin addicts

This study attempts to analyse potential gender differences among a group of heroin addicts seeking treatment at a university-based medical centre. The central modality of treatment at this centre is the use of methadone maintenance. Among those patients entering this program there seems to be an emerging pattern of males who tend to use heroin as their opiate of choice, and are more likely to combine it with cannabis, while females are more likely to use to street methadone, with adjunctive use of ketamine, benzodiazepines, hypnotic drugs and/or amphetamines. Women are at higher risk of abusing opioids through a pathway of initial prescription painkiller use, and later to resort to street methadone to cope with prescription pain killer addiction. This latter pattern seems to result in an increased risk for fatal accidental overdoses. The use of these longer-acting agents in women may be influenced by psychosocial and hormonal factors.

Sex differences in patients with schizophrenia: A prospective, multi-center study

This study aimed to determine sex differences in socio-demographic and clinical characteristics of Chinese schizophrenia patients. In a multi-center, randomized, controlled, longitudinal study, 404 clinically stable patients with schizophrenia were randomly assigned to a maintenance group (optimal therapeutic doses continued throughout the study), a 26-week group (optimal therapeutic doses continued for 26 weeks, followed by a 50% dose reduction maintained until the end of the study), or a 4-week group (optimal therapeutic doses continued for 4 weeks, followed by a 50% dose reduction maintained until the end of the study). Participants were interviewed regularly using standardized assessment instruments, and followed up for 12-26 months. In the univariate analyses, the following factors were significantly associated with the male sex: not married, smoking, younger age, earlier age at onset, higher body mass index (BMI) at baseline, and more severe negative and hostility-excitement symptoms at baseline. The following factors were independently associated with the male sex in the multivariate analyses: not being married, smoking, a higher BMI at baseline, less deterioration in disorganized thoughts (4-week group) and positive symptoms (26-week group) and less increase in BMI in all three treatment groups over the study period. The majority of the sex differences in schizophrenia patients in this study are in accordance with results of previous studies worldwide suggesting that sex differences seen in schizophrenia are not dependent on cultural differences between geographically separate patients.

Gender differences in sociodemographic and clinical characteristic and the quality of life of Chinese schizophrenia patients

OBJECTIVE

The aim of the present study was to determine the sociodemographic and clinical correlates of the gender of Chinese schizophrenia outpatients and their impact on patients quality of life (QOL).

METHODS

Two hundred and fifty-five clinically stable schizophrenia outpatients were randomly selected in Hong Kong. Counterparts matched according to gender, age, age at onset, and length of illness were recruited in Beijing, China. All of the subjects at both sites were interviewed by the same investigator using standardized assessment instruments.

RESULTS

The combined Beijing-Hong Kong sample contained 251 male and 254 female patients. On univariate analysis more male patients were employed, they had a significantly higher monthly income, and took higher doses of antipsychotic drugs. No difference was found, however, in any of the QOL domains between the genders. On multivariate analysis being employed, taking a higher dose of antipsychotic drugs, having more severe extrapyramidal side-effects, and a higher score on the physical domain of QOL were independently associated with male gender.

CONCLUSION

Female gender is independently associated with lower scores on the physical aspects of QOL, but there is no difference between the genders in the psychological, social and environmental aspects.

Family intervention for co-occurring substance use and severe psychiatric disorders: participant characteristics and correlates of initial engagement and more extended exposure in a randomized controlled trial

Clients with severe mental illness and substance use disorder (i.e., dual disorders) frequently have contact with family members, who may provide valuable emotional and material support, but have limited skills and knowledge to promote recovery. Furthermore, high levels of family conflict and stress are related to higher rates of relapse. The present study was a two-site randomized controlled trial comparing a comprehensive, behaviorally-based family intervention for dual disorders program (FIDD) to a shorter-term family psychoeducational program (FPE). The modal family was a single male son in his early 30s diagnosed with both alcohol and drug problems and a schizophrenia-spectrum disorder participating with his middle-aged mother, with whom he lived. Initial engagement rates following consent to participate in the study and the family intervention programs were moderately high for both programs (88% and 84%, respectively), but rates of longer term retention and exposure to the core elements of each treatment model were lower (61% and 55%, respectively). Characteristics of the relatives were the strongest predictors of successful initial engagement in the family programs with the most important predictor being relatives who reported higher levels of benefit related to the relationship with the client. Subsequent successful exposure to the family treatment models was more strongly associated with client factors, including less severity of drug abuse and male client gender. The results suggest that attention to issues of motivating relatives to participate in family intervention, and more focused efforts to address the disruptive effects of drug abuse on the family could improve rates of engagement and retention in family programs for dual disorders.

Psychosocial treatments for people with co-occurring severe mental illnesses and substance use disorders (dual diagnosis): a review of empirical evidence

Considerable research documents the health consequences of psychosis and co-occurring substance use disorders. Results of randomized controlled trials assessing the effectiveness of psychosocial interventions for persons with dual diagnoses are equivocal but encouraging. Many studies are hampered by small, heterogeneous samples, high attrition rates, short follow-up periods, and unclear description of treatment components. The treatments available for this group of patients (which can be tailored to individual needs) include motivational interviewing, cognitive-behavioral therapy, contingency management, relapse prevention, case management, and skills training. Regardless of whether services follow integrated or parallel models, they should be well coordinated, take a team approach, be multidisciplinary, have specialist-trained personnel (including 24-hour access), include a range of program types, and provide for long-term follow-up. Interventions for substance reduction may need to be further developed and adapted for people with serious mental illnesses. Further quality trials in this area will contribute to the growing body of data of effective interventions.

Schizophrenia and violence: accepting and forsaking

Violence remains highly problematic for women. Women diagnosed with schizophrenia are at particularly high risk for numerous types of violence. Many of these women receive services in the community through mental health case managers. These case managers have developed ongoing and close relationships with women, and are often the front-line service providers to assist them in negotiating with physical, mental, and social service agencies. This interpretive phenomenological study examined the perspective of mental health case managers to better understand how they cope with the intersection of violence with a diagnosis of schizophrenia among their clientele. Accepting and forsaking was a theme developed to describe how case managers gradually accepted violence in the lives of women with schizophrenia, and how this acceptance was eventually coupled with forsaking hope for a reduction or elimination of violence in women's lives.

Women, psychosis and violence

Psychosis confers a disproportionate risk of violence on women compared with men, but such women barely affect national crime statistics anywhere. Much research in the field does not include women at all. In our literature review, we found that information about women, psychosis and violence generally had to be extracted from studies including women but focussing on men; not uncommonly analyses 'controlled for gender' rather than treating it as interesting in itself. A tendency for women to be older than men at onset of psychosis may not apply to those who become violent, but women with psychosis do seem to start offending later and desist sooner. Rates of seriously adverse childhood experiences are similar between women and men with psychosis, except for sexual abuse-more frequently reported by the women. Some evidence of special patterns for women in the nature of psychosis and violence relationships requires more exploration, as do treatment questions. With so few women in any one service, multi-centre co-operation in research with them will be essential.

Racial/Ethnic Differences in Dually Diagnosed Anglo and Ethnic Minority Women Receiving Chemical Dependency Treatment

This article examines racial/ethnic differences in a sample of 51 dually diagnosed women who received chemical dependency treatment. Comparisons are made between Anglo and racial/ethnic minority women at admission to the inpatient treatment program and at follow-up where data are available. Findings from a repeated measures design showed significant decreases in several problem domains for the overall sample. Significant racial/ethnic differences were found only for the other drugs domain. Anglo women reported greater decreases than racial/ethnic minority women in the majority of the domains. Findings suggest continued investigations to inform culturally competent treatment for all dually diagnosed women.

Women with and without intellectual disability and psychiatric disorders: an examination of the literature

This article examines the literature on women with and without intellectual disability and psychiatric disorders, using a gender social model of health. Relevant empirical studies, international literature reviews and policies between 1980 and 2007 were identified from electronic databases, journals and secondary sources. Three areas were examined: psychiatric disorders, their contextual background, and their clinical presentation. There are minimal levels of research into women with intellectual disability and psychiatric disorders. However, this article hypothesizes that women with intellectual disability have higher rates of psychiatric disorders than women without. This may result from greater vulnerability related both to internal factors (;intra': cognitive deficits, poorer communication skills, limited social skills) and to the external world (;inter': lack of opportunities, stigma, poor social support networks). The article argues that such women require gender-sensitive mental health services. However, more empirical evidence is required to support this claim and to inform development and delivery of services.

Perpetration of violence, violent victimization, and severe mental illness: balancing public health concerns

OBJECTIVE

This review examined U.S. empirical studies published since 1990 of the perpetration of violence and of violent victimization among persons with severe mental illness and their relative importance as public health concerns.

METHODS

MEDLINE, PsycINFO, and Web of Science were searched for published empirical investigations of recent prevalence or incidence of perpetration or victimization among persons with severe mental illness. Studies of special populations were included if separate rates were reported for persons with and without severe mental illness.

RESULTS

The search yielded 31 studies of violence perpetration and ten studies of violent victimization. Few examined perpetration and victimization in the same sample. Prevalence rates varied by sample type and time frame (recall period). Half of the studies of perpetration examined inpatients; of these, about half sampled only committed inpatients, whose rates of perpetration (17%-50%) were higher than those of other samples. Among outpatients, 2% to 13% had perpetrated violence in the past six months to three years, compared with 20% to 34% who had been violently victimized. Studies combining outpatients and inpatients reported that 12% to 22% had perpetrated violence in the past six to 18 months, compared with 35% who had been a victim in the past year.

CONCLUSIONS

Perpetration of violence and violent victimization are more common among persons with severe mental illness than in the general population. Victimization is a greater public health concern than perpetration. Ironically, the discipline's focus on perpetration among inpatients may contribute to negative stereotypes.

The invisibility of violence against women diagnosed with schizophrenia: a synthesis of perspectives

Women diagnosed with severe mental illness experience twice the rates of violence compared with women without mental illness. Despite awareness of violence, mental healthcare providers feel powerless to combat the problem. This article synthesizes 2 previous interpretive studies that examined violence perpetrated against women diagnosed with schizophrenia. This synthesis critically examines the perspectives of women who experience violence and schizophrenia and case managers who care for them. Stigma was an overarching theme in participants' stories but each group differed in its understanding of how stigma impacted women's lives. This disconnection perpetuates stigma and allows violence to remain invisible.

Gender differences in 542 Chinese inpatients with schizophrenia

OBJECTIVE

To investigate gender differences in the onset and other clinical features of Han Chinese inpatients with schizophrenia.

METHODS

Five-hundred-and-forty-two Han Chinese inpatients with DSM-IV schizophrenia were assessed with the Positive and Negative Symptoms Scale (PANSS), the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Function scale (GAF) and locally-developed standardized data collection forms. Comparisons were made between male and female patients.

RESULTS

This is the largest study of gender differences in schizophrenia to be conducted in a Chinese population. In our sample, we found that schizophrenia onset occurred at a significantly earlier age in male patients compared to female patients and that late-onset schizophrenia (as defined by onset> or =45 years) was significantly more common in female patients. The paranoid subtype of schizophrenia was less common in male patients, males received higher daily doses of antipsychotics and demonstrated a different pattern of antipsychotic usage, being less likely to be treated with SGAs. Further, cigarette smoking was more common in male patients and male patients were more likely to be single or never married. By contrast, female patients showed a different pattern of ongoing symptoms and severity, being more likely to have persistent positive symptoms, more severe positive and affective symptoms, and a greater number of suicide attempts whereas male patients were more likely to show severe deterioration over time.

CONCLUSIONS

There are notable gender differences in the age at onset, treatment and a range of other clinical features in Han Chinese patients with schizophrenia. Such differences were largely consistent with those reported in Western studies. These gender differences need to be considered in the assessment and management of Chinese patients with schizophrenia.

Patterns of alcohol use between genders: a cross-cultural evaluation

INTRODUCTION

Alcohol use by men and women is very much influenced by social habits and customs. Cultural peculiarities and biological differences between the sexes require more focused and standardized studies. The objective was to systematize information on patterns of alcohol use between the sexes.

METHOD

A literary review (1972-2004) identified 96 publications (Lilacs, Scielo, Medline) and some related books.

RESULTS AND CONCLUSIONS

Men drank more and presented more problems (legal, family, social, clinical, traumas and mortality) associated with alcohol use; the consequences of alcohol use in developing countries with low death rates is even higher. Women can face more discrimination by using alcohol as well as worse health problems when they abuse drinking (liver, pancreas, and central and peripheral nervous system problems, psychiatric comorbidity, etc.); sexual abuse is more commonly associated with women than discussing the different responses to treatment. As for social roles/responsibilities exercised by women, there are indications that marriage, employment, and children have a good influence, discouraging alcohol use, while divorce, unemployment, and no children contribute to higher consumption. For both sexes, religion was a protective factor for alcohol use; acculturation was a strong influence in the pattern of alcohol use, and alcohol worsened the evolution of existing psychiatric disorders.

Gender differences in young adults with first-episode schizophrenia spectrum disorders at baseline in the Danish OPUS study

Gender differences in age at first onset, duration of untreated psychosis, psychopathology, social functioning, and self-esteem were investigated in a group of 578 young adults with a first-episode schizophrenia spectrum disorder. The mean age at first-onset of symptoms, age at first contact, and duration of untreated psychosis were similar for men and women. Men had more severe negative symptoms, poorer premorbid functioning, and poorer social networks, whereas women had more severe hallucinations. More men than women were substance abusers, were unemployed, and lived alone. Women had poorer self-esteem than men, in spite of better scores in functioning. Premorbid social adjustment was significantly related to the level of negative symptoms and number of friends. Conclusion is that men and women with first-episode psychosis showed different psychopathological characteristics and different social functioning, which cannot be explained by older age of onset for women. Women make more suicide attempts and experience lower self-esteem in spite of better social functioning.

Schizophrenia and violence: the perspective of women

Violence against women is a major public health problem. Women with a diagnosis of schizophrenia suffer higher rates of violence compared with women without mental illnesses. Little research has focused on what it means for women to live with schizophrenia and a history of violence. This interpretive phenomenological study identified three themes of schizophrenia and violence: Being Stigmatized, Foreclosing a Future of Possibilities, and Finding Meaning in Symptoms. The results suggest mental health professionals should assess women with diagnoses of schizophrenia for violence and provide opportunities for trauma stories to be heard. These listening types of patient-centered interventions may promote recovery.

The role of coercion in the treatment of women with co-occurring disorders and histories of abuse

Debate continues on issues of involuntary treatment for individuals with behavioral healthcare problems. Women with co-occurring disorders and histories of abuse are an especially vulnerable population. This study seeks to increase our knowledge about the experiences of coercion for women in the behavioral healthcare system. Patterns of coercion are explored. This study did not find the predicted relationship between high levels of interpersonal violence and frequent involuntary treatment experiences. The results do offer support for the hypothesis that women are more likely to be currently mandated to treatment if they have been recently arrested, and that being mandated to treatment does not appear to be related to clinical issues such as recidivism and acute symptoms. As expected, women currently required to be in treatment report having less choice in other aspects of their care. Implications for future research in the current climate of increasingly coercive policies are presented.

A review of treatments for people with severe mental illnesses and co-occurring substance use disorders

Several interventions for people with co-occurring severe mental illnesses and substance use disorders have emerged since the early 1980s. This paper reviews 26 controlled studies of psychosocial interventions published or reported in the last 10 years (1994-2003). Though most studies have methodological weaknesses, the cumulative evidence from experimental and quasi-experimental research supports integrating outpatient mental health and substance abuse treatments into a single, cohesive package. Effective treatments are also individualized to address personal factors and stage of motivation, e.g., engaging people in services, helping them to develop motivation, and helping them to develop skills and supports for recovery. Accumulating evidence from quasi-experimental studies also suggests that integrated residential treatment, especially long-term (one year or more) treatment, is helpful for individuals who do not respond to outpatient dual disorders interventions. Current research aims to refine and test individual components and combinations of integrated treatments.

Substance use disorders: sex differences and psychiatric comorbidities

OBJECTIVE

This article reviews sex differences in psychiatric comorbidity among individuals with substance use disorders and, in particular, the clinical significance of these differences for treatment outcome among women.

METHOD

We undertook a computerized search of major health care databases. To enhance the search, we drew prior relevant articles from the reference list.

RESULTS

Women with alcohol and other drug use disorders present higher rates of psychiatric comorbidity, particularly mood and anxiety disorders, than do men. Moreover, the comorbid diagnosis, particularly of depression, is more often primary in women, while in men the comorbidity is more often secondary to the substance abuse diagnosis. In addition, there is evidence that psychiatric comorbidity is associated with distinct, sex-specific outcomes for substance use treatment.

CONCLUSIONS

Sex differences in the clinical presentation of substance-dependent individuals with psychiatric comorbidity present specific treatment challenges and opportunities.

Treatment concerns of women with co-occurring serious mental illness and substance abuse disorders

The treatment needs of persons with co-occurring mental illness and substance abuse disorders is a relatively new area of inquiry. Even less information is available concerning the treatment concerns of women with dual diagnosis. A focus group was conducted with seven women as part of a larger study of effective treatments for adults with co-occurring disorders. Women responded to questions about what worked and what did not work in their past treatment experiences and what needs to be added for effective treatment. Five primary themes emerged: negative treatment experiences, negative system experiences, desirable treatment characteristics, therapeutic client characteristics, and life issues affecting treatment engagement. Two of the main treatment recommendations that emerged were the need for advocacy assistance with child protective service agencies and the need for providers to use client-centered treatment methods.

Substance misuse in patients with schizophrenia: epidemiology and management

Substance misuse in individuals with schizophrenia is very common, especially in young men, in communities where use is frequent and in people receiving inpatient treatment. Problematic use occurs at very low intake levels, so that most affected people are not physically dependent (with the exception of nicotine). People with schizophrenia and substance misuse have poorer symptomatic and functional outcomes than those with schizophrenia alone. Unless there is routine screening, substance misuse is often missed in assessments. Service systems tend to be separated, with poor inter-communication, and affected patients are often excluded from services because of their comorbidity. However, effective management of these disorders requires a fully integrated approach because of the close inter-relationship of the disorders. Use of atypical antipsychotics may be especially important in this population because of growing evidence (especially on clozapine and risperidone) that nicotine smoking, alcohol misuse and possibly some other substance misuse is reduced. Several pharmacotherapies for substance misuse can be used safely in people with schizophrenia, but the evidence base is small and guidelines for their use are necessarily derived from experience in the general population.

Community mental health care for women with severe mental illness who are parents

Women with SMI are involved in childbearing and childrearing, but may have problems with parenting related to symptoms, lack of knowledge and skills, or lack of environmental supports. They may need intensive services to manage their mental illness and to parent to the best of their abilities. Preliminary research suggests that mental health interventions can improve family functioning, but that these services are not widely available in community mental health systems. This paper describes services to help clients who are parents, which includes integration of adult's and children's services, long-term, home-based parent training, and linkage with community supports.

The role of sex hormones in psychopathology: focus on schizophrenia

The example of schizophrenia is used to illustrate how sex hormones affect the presentation of illness and its treatment. Organization and activation effects of hormones are explained, and behavior is shown to result from a complex interplay of hormones, brain mechanisms, and social pressures. Sex differences in schizophrenia (in onset age, symptoms, antipsychotic, and other treatment) are consequences of this interplay and impact on the clinician's ability to diagnose, treat, prognosticate, and prevent the disability and distress of schizophrenia.

Gender differences in dually-diagnosed clients receiving chemical dependency treatment

This article considers gender differences among 97 clients with dual diagnoses of severe mental illness and chemical dependency (46 male and 51 female). Comparisons are made at the time of their admission to an inpatient chemical dependency treatment program and at follow-up in cases where data are available. Many of the findings at time of admission are consistent with the few studies that have compared men and women with co-occurring mental and substance use disorders. For example, the women were more likely to have experienced emotional, physical, or sexual abuse, and they reported being charged with fewer types of crimes. Most differences at admission concerned psychiatric problems and family/social relations. Women reported that they were more bothered by their psychiatric symptoms and their family/social relations, but they also reported more happiness and closeness in some relationships. The women also said they had more relatives with alcohol, drug, and especially psychiatric, problems. At follow-up, gender differences in the family/social and psychiatric domains persisted. Findings suggest that men and women with dual diagnoses might benefit from different emphases in treatment programs.

Managing comorbid schizophrenia and substance abuse

Effective treatments for co-occurring schizophrenia and substance abuse have emerged over the past 15 years. They involve integration and melding of mental health and substance abuse treatments, helping people to acquire the skills and supports they need to manage both illnesses and to pursue functional goals, and a comprehensive, long-term approach to recovery. Further research is needed to refine specific interventions and to improve knowledge regarding implementing integrated treatment settings in routine mental health programs.

Mental health versus substance abuse treatment programs for dually diagnosed patients

The aim of this study was to assess the similarities and differences of patients with co-existing psychiatric and substance use disorders attending treatment in either a mental health setting or a substance abuse treatment setting. A total of 129 patients were assessed, including 65 individuals from the substance abuse treatment center and 64 individuals from the mental health program. Treatment records were reviewed for diagnoses and sociodemographic data. While the two groups were highly similar with regard to age and ethnicity, there were significant differences in psychiatric profile, with the substance abuse treatment group having less severe diagnoses and no patients with schizophrenia, while the mental health treatment group had a majority of patients with schizophrenia. Other differences in the two groups, such as marital and parental status, disability status, and medical problems appeared to be directly linked with the aforementioned diagnostic profile. These data suggest important differences in characteristics of patients with comorbid disorders that appear to be dependent on the type of treatment program they attend. For the most effective management, integrated treatment programs should be aware of these differences and tailor service provision accordingly.

Addiction and schizophrenia

Epidemiologic studies in the general population and those based on the clinical assessment of schizophrenic populations have revealed a high degree of overlap between schizophrenia and addictive disorders. The abuse of psychoactive substances (including alcohol) throughout life is so frequent (50%) that the possibility of a specific link inevitably arises. Various hypotheses have been suggested to explain the high co-morbidity between schizophrenia and addiction: 1) The social-environmental hypothesis has been developed but studies have provided poor evidence to validate it. 2) The possible shared biological vulnerability between schizophrenia and addictions led researchers to explore common genetic determinants and study the involvement of the dopaminergic and opioid systems in the aetiology of both schizophrenia and the abuse of and dependence on psychoactive drugs. 3) Finally, the theory of self-medication suggests that schizophrenics may be attempting to counter the deficit linked to their disorders by using the substances they take or their dependency-type behaviour to cope with their emotional problems. The clinical profile of schizophrenic addicts does seem to display some distinctive features, such as the high level of depressive co-morbidity, very high nicotine and alcohol dependence, with a very poor prognosis. These patients are difficult to manage; the possibility of pharmacologic interactions between the substances they are taking and neuroleptic medication calls for prudence, and their compliance is also poor. Addictive disorders in schizophrenics are currently a topic of active research intended to lead to identifying specific treatments. The early identification of addictive disorders in schizophrenics should make it possible to limit their development and improve the prognosis.

Gender differences in homeless persons with schizophrenia and substance abuse

The purpose of this study was to test the generalizability of previous research on gender differences between men and women with co-occurring schizophrenia and substance abuse. One hundred eight patients with schizophrenia or schizo-affective disorder involved in a study of treatment for homeless persons were interviewed for information regarding substance use, social functioning and support, comorbid disorders, victimization, medical illness, and legal troubles. We found that women had more children and were more socially connected than men. Women also had higher rates of sexual and physical victimization, comorbid anxiety and depression, and medical illness than men. We conclude that homeless women with dual disorders, like women with substance use disorders in the general population, have distinct characteristics, vulnerabilities, and treatment needs compared with men. In addition to comprehensive treatment of psychiatric and substance use disorders, gender-specific services should be developed, including prevention and treatment of victimization and related problems as well as help with accessing medical services.
