Effects of gender and diagnosis on addiction history, treatment utilization, and psychosocial functioning among a dually-diagnosed sample in drug treatment

Substance Use Disorders in Women

Substance use disorder (SUD) is among the leading causes of premature morbidity and mortality and imposes significant health, economic, and social burdens. Gender differences have been found in the development, course, and treatment of SUD, with women at increased risk for physiologic and psychosocial consequences compared with men. Reasons for these differences are multifold and include biological, genetic, environmental, and behavioral factors. This article discusses SUD among women, emphasizing clinical considerations for care. Specific topics include epidemiology, sex and gender differences, common comorbidities, screening, diagnosis, treatment, pregnancy, and sociocultural factors.

A systematic review of gender-responsive and integrated substance use disorder treatment programs for women with co-occurring disorders

Background: Integrated and gender-responsive interventions, designed to target co-occurring substance use and psychiatric disorders in women, may be effective in addressing gender-specific challenges.Objectives: This systematic review aims to identify integrated gender-responsive substance use disorder treatments for women, summarize evaluations of these treatments, and address gaps in the literature.Methods: We searched PsycINFO, PubMed, and MEDLINE on September 24, 2021, and March 10, 2022. Included articles were randomized-controlled trials, secondary analyses of naturalistic studies, or open-label studies of integrated and gender-responsive treatments from any year that assessed both substance use and mental health/trauma outcomes.Results: We identified N = 24 studies (participants = 3,396; 100% women) examining Seeking Safety, Helping Women Recover and Beyond Trauma, A Woman's Path to Recovery, Modified Trauma Recovery and Empowerment Model (TREM), Breaking the Cycle, VOICES, Understanding and Overcoming Substance Misuse, Women's Recovery Group, Female Specific Cognitive Behavioral Therapy, and Moment by Moment in Women's Recovery. Across treatments there were significant improvements over time; Seeking Safety, Helping Women Recover, and TREM were associated with significantly better substance use and mental health outcomes relative to the comparison groups.Conclusions: Integrated gender-responsive treatments are a promising approach to treating women with co-occurring substance use and mental health concerns, and broad clinical implementation stands to benefit women. However, there remains a lack of studies evaluating substance use treatments in women with severe mental illness (e.g., psychotic-spectrum disorders) who differ in their needs and capacity.

Posttraumatic stress disorder with secondary psychotic features (PTSD-SP): Diagnostic and treatment challenges

Trauma exposure leads to various psychiatric disorders including depression, anxiety, bipolar disorders, personality disorders, psychotic disorders, and trauma related disorders, especially posttraumatic stress disorder (PTSD). There are some overlapping symptoms of both PTSD and psychosis that make diagnosis challenging. Despite this overlap, the evidence of PTSD with comorbid psychosis as a distinct entity lies in the research showing biologic, genetic and treatment management differences between psychotic PTSD, non-psychotic PTSD, psychotic disorders and healthy controls. There is emerging evidence that PTSD with secondary psychotic features (PTSD-SP) might be a discrete entity of PTSD with known risk factors that increase its prevalence. This review has presented evidence for individuals with PTSD-SP being distinct in genetics and neurobiological factors. Individuals with PTSD and comorbid psychosis can benefit from evidence based psychotherapy (EBT). There is not enough evidence to recommend second generation antipsychotics (SGA) for PTSD-SP given that risperidone and quetiapine are the only SGAs studied in randomized controlled trials. Hence, developing an operational diagnostic criteria and treatment framework for clinical and research use is critical.

The Temporal Relationship between Selected Mental Disorders and Substance-Related Disorders: A Nationwide Population-Based Cohort Study

Introduction. Previous studies have examined the association between specific mental disorders, particularly mood and anxiety disorders, and substance-related disorders; but the temporal link between them remains unclear. This study aimed to examine whether individuals with specific mental disorders, including affective psychoses, neurotic disorders, schizophrenia, personality disorders, and adjustment reaction, have higher risks for subsequently developing substance-related disorders compared to those without. Methods. A large-scale study with longitudinal data was conducted using the Taiwan National Health Insurance Research Database (NHIRD) consisting of 2,000,118 patients' medical records from 2000 to 2009. A total of 124,423 people diagnosed with selected mental disorders and the same number of people without the diagnoses of the selected disorders were identified between January 1, 2001, and December 31, 2006, and followed up for the diagnoses of substance-related disorders till the end of 2009. We estimated the risk for subsequently developing substance-related disorders among patients with the selected mental disorders compared to those without by using Cox proportional hazard models. The cumulative incidence of substance-related disorders was calculated using the Kaplan-Meier method. Results. The risk for developing substance-related disorders in patients with selected mental disorders is about 5 times (HR=5.09, 95% CI: 4.74-5.48) higher than those without after adjusting for potential confounding variables. From the multivariate analyses of subsamples stratified by age, sex, and urban and income levels, we found all adjusted hazard ratios were significantly higher than 1.0, ranging from 2.12 (95% CI: 1.72-2.62) to 14.55 (95% CI: 7.89-26.83). For children and adolescents aged 10-19 years, those with specific mental disorders had 14.55-fold higher risk for developing substance-related disorders in later life compared to their counterparts. Furthermore, patients with personality disorders had the highest risk (HR=25.05). Conclusions. The earlier onset of the selected mental disorders is a potential risk for developing substance-related disorders in later life, particularly for personality disorders. Health professionals should pay more attention to this at-risk population, especially to adolescents with mental disorders.

Alcoholics Anonymous-Related Benefit for Urban Native Americans: Does Urban Native American Gender Moderate AA Engagement and Outcomes?

Alcoholics Anonymous (AA) is one of the most commonly accessed resources for individuals seeking to reduce their drinking. How urban Native Americans fare in AA is only beginning to be investigated in spite of circumstantial evidence suggesting that a majority of treatment-seeking urban Native Americans will receive 12-step treatment. Even less is known about Native American gender differences with regard to AA-related benefit. The current study addressed this gap by investigating urban Native American gender differences in AA attendance rates and outcomes. To this end, as part of two larger NIH-funded studies we recruited 63 Native American men and women and followed them for 9 months in this naturalistic study (n= 35 males, n = 28 females). Urban Native Americans significantly reduced their drinking over the study period, and AA attendance explained, in part, increased abstinence of study participants. No significant differences in AA attendance and drinking outcomes were observed between Native American men and women; however, descriptively men reported greater reductions in hazardous drinking relative to women. Clinical implications and future directions are discussed.

Hur gick det för 1960- och 1970-talets svenska narkotikamissbrukare?

What happened to the Swedish problem drug users of the 1960's and 1970's?

AimS & DESIGN

– In this study we follow a Stockholm birth cohort born in 1953 (n= 14 294) from youth to middle age. The cohort members were in their teenage years when drug abuse was established as a considerable threat to Swedish society and some of the cohort members themselves became drug abusers (n=431).

Results

– As expected, life became dramatically worse for those with documented drug abuse when young, than for the rest of the cohort members. While 72 percent of those without documented drug abuse were socially included at the age of 56, the corresponding share among those with documented drug abuse was 18 per cent. And while 5 percent in the former group were diseased at 56, this was true for 38 percent in the latter group. Supplementary analyses showed that social inclusion was also less stable among those with documented drug abuse than among the rest of the cohort, and that the flow from exclusion to inclusion was virtually nonexistent, which was not the case for those without experience of drug abuse.

Conclusions

– Gender specific analyses showed that the situation, at least in absolute terms, tended to be even worse for male drug abusers than for women. Gender differences in alcohol abuse, criminality, and with respect to parenthood are suggested as possible explanations to be further studied in future research.

Typology of individuals with substance dependence based on a Montreal longitudinal catchment area study

This study sought to develop a typology of individuals with substance dependence (ISD) based on a longitudinal survey (n = 2,434) and 121 ISD. The latter were divided into three groups: newly abstinent individuals, chronic dependents and acute dependents. Individuals' typology was developed by cluster analysis. Newly abstinent individuals had fewer emotional problems and mental disorders in the previous 12 months. Four classes of ISD were identified, labelled respectively "chronic multi-substance consumption and mental disorders comorbidities," "multi-substance consumption," "alcohol and marijuana consumption" and "alcohol consumption only." Strategies adapted to each of these profiles could be promoted for more effective treatment.

Psychosocial problems among individuals with substance use disorders in drug rehabilitation centers, Nepal

BACKGROUND

Substance use is associated with numerous undesirable short and long term consequences. The individual not only suffer from physical and psychological problems but also loses the ability to interact with family, peers and society. The present study aims to identify the psychosocial problems and associated factors among individuals with substance use disorders.

METHODS

The study was conducted using descriptive cross sectional research design in different drug rehabilitation centers of Nepal. Probability proportional to size sampling technique was used to select the drug rehabilitation centers and individuals diagnosed with substance use disorder but free from any substance withdrawal features, admitted in rehabilitation centers within 3 months and clients above 15 years of age were included in the study (N = 204). A standard tool Drug Use Screening Inventory-Revised was used to assess the psychosocial problems and the scores ranged from 0 to 100. The data were analyzed using descriptive and inferential statistics. Linear regression analysis was conducted to identify the predictors of psychosocial problems.

RESULTS

The mean and standard deviation of overall psychosocial problems scores was 60.42 ± 19.44. Among different domains, more problems were found in substance use domain (75.00 ± 21.43) followed by school performance (64.60 ± 25.53), behavior pattern (64.53 ± 24.44), peer relationship (64.49 ± 24.91), social competence (61.30 ± 22.60), psychiatric disorder (56.83 ± 23.39), family system (48.28 ± 23.72) and work adjustment (45.90 ± 29.88) domains. Types of substance use, mode of substance use and age of initiation of substance use were the significant predictors of overall and most of the domains of psychosocial problems.

CONCLUSION

Substance use poses significant impact on individual's psychological and social wellbeing. Individuals using injecting drugs, initiating substances early in life, using substances many times in a day and using both licit and illicit substances had more psychosocial problems. Hence, treatment centers should take this into account.

Utilization of Substance Abuse Treatment: Gender Differences among Participants in an Aftercare Program

This study examined gender differences in the utilization of substance abuse treatment including inpatient, outpatient, and self-help services, using existing data sets from a National Institute on Drug Abuse study that enrolled 78 females and 141 males in a mixed-gender aftercare program in Massachusetts for a 2-year follow-up period. This study found that women came to the study in greater need of treatment than men. Women utilized significantly more outpatient treatment services than men. The characteristic of female per se led to more utilization of outpatient services, whereas the baseline characteristics of employed status and alcohol use led to less utilization of outpatient services.

Maternal mental health and children's internalizing and externalizing behaviors: Beyond maternal substance use disorders

Maternal substance abuse and mental disorders can have adverse impacts on child development. We investigated the impact of maternal mental health on child behaviors based on a long-term follow-up study of mothers and their children approximately 10 years after mothers' admission to drug abuse treatment. Mothers (n=396) were assessed at admission to drug treatment during 2000 to 2002, and at follow-up in 2010-2011. At follow-up, each mother was asked to assess one target child using the Child Behavior Checklist for ages 6-18 (CBCL). Mothers' mental disorder diagnoses were obtained from records maintained by the California Department of Mental Health in 2009. About 46% of mothers had comorbid mental disorders; 27% had depressive disorder, 15% bipolar disorder, 15% adjustment disorder, 13% anxiety disorder, and 6% psychotic disorder. Of these mothers, more than half had two or more mental disorder diagnoses. The average age of the target child was approximately 10 years old (range 6 to 17). Relative to children of mothers without comorbid mental disorders, children were more likely to demonstrate internalizing behaviors if their mothers had comorbid depression/anxiety disorders (OR=2.0, 95%CI:1.0-4.0) or severe mental disorders (psychoses, bipolar) (OR=3.4, 95%CI:1.5-7.6). For externalizing behaviors, family problems was the only significant predictor (OR=3.2, 95%CI:1.7-6.0 for children of mothers with depression/anxiety disorders, OR=3.9, 95%CI:1.9-7.8 for severe mental disorders). Addressing maternal mental disorders (particularly severe mental disorders) and family problems are important for child well-being as these factors were significantly related to emotional and problem behaviors of children.

Gender differences in mortality and risk factors in a 13-year cohort study of street-recruited injecting drug users

BACKGROUND

Injecting drug users (IDUs) are at risk of premature mortality. This study examined gender differences in mortality, risk factors, and causes of death among IDUs.

METHODS

In a 13-year cohort study including 172 street-recruited IDUs from Oslo, Norway in 1997, interview data was merged with the National Cause of Death Registry. Crude mortality rate (CMR) and indirect standardized mortality ratio (SMR) were estimated with 95% confidence intervals (CI). A log-logistic multivariate survival analysis model was estimated for the full sample. For a smaller data set (1.1.1998-31.12.2004) the influence of substitution treatment and prison were assessed using cox regression survival analysis.

RESULTS

Eight females and 37 males died. Acute intoxications were the most common cause of death. Women were more at risk in the short-term, but more protected in the long-term. CMR was 16.0 [95% CI 8.0, 31.9] for women and 26.0 [95% CI 18.0, 35.8]) for men. SMR was 39.4 [95% CI 0.2, 220.8]) for women and 21.3 [95% CI 5.7, 54.1] for men. More women injected heroin (98% vs. 88% [x2 = 3.5, p = 0.063]), used prescription drugs (73% vs. 52% [x2 = 5.6, p = 0.018]) and combined these to inject (45% vs. 26% [x2 = 5.9, p = 0.015]). Mixing prescription drugs in heroin injections, and sex work (only women) were associated with decreased survival time. There were no gender differences in access to substitution treatment, while significantly more men had been in prison (74% vs. 51% [x2 = 7.5, p = 0.006]). The instance of substitution treatment and prison significantly decreased the mortality risk. Prison release increased the risk, but not statistically significantly.

CONCLUSIONS

There were gender differences in mortality and risk factors; sex work and prison were gender specific risk factors. These factors should be investigated further to better design future preventive measures.

Predictors of alcohol and drug dependence

OBJECTIVE

Our study sought to identify sociodemographic, clinical, life perception, and service use characteristics that distinguish new cases of people dependent on substances from the general population; and to determine predictors of substance dependence over a 2-year period. Variables that differentiate people dependent on substances according to sex and age were also assessed.

METHODS

Among 2434 people who took part in an epidemiologic catchment area health survey at baseline, 2.2% were identified with substance dependence at the second measurement time only. Using a comprehensive framework, various aspects were considered as predictors for multivariate statistics.

RESULTS

Participants with substance dependence at time 2 only showed worse clinical conditions, life events, life and health perception, and neighbourhood characteristics than other participants, but only 2.5% used health care services. Male sex, younger age, stigmatization, and impulsiveness were predictors of substance dependence. Regarding sex, females with dependence were only more likely to suffer from social phobia than males. In terms of age categories, participants over 50 with substance dependence were more likely to have a lower household income and less social support than younger people.

CONCLUSION

Stigmatization was the strongest predictor of substance dependence. Our study also confirmed that males and younger people were more likely to have substance dependence. Anti-stigmatization, prevention, and outreach programs are needed to overcome the reluctance of this clientele to use health care services. Health professionals should also pay more attention to life and health perception and neighbourhood characteristics of newly identified drug users.

Sex differences in prevalence and comorbidity of alcohol and drug use disorders: results from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions

OBJECTIVE

The present study examined sex differences in lifetime Axis I and II psychiatric comorbidity of DSM-IV alcohol use disorders (AUDs) and drug use disorders (DUDs) among general population U.S. adults.

METHOD

Using data from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions, Wave 2 lifetime prevalences of each disorder comorbid with alcohol abuse, alcohol dependence, drug abuse, and drug dependence were compared between men and women. Sex-specific associations of alcohol, any drug, and cannabis- and cocaine-specific abuse and dependence with each comorbid disorder were examined using logistic regression, first with adjustment for sociodemographic variables and then with additional adjustment for all other psychiatric disorders.

RESULTS

Prevalences of most comorbid disorders differed significantly by sex among respondents with each AUD and DUD. However, after adjustment for sociodemographic characteristics and additional co-occurring psychiatric diagnoses, there were few sex differences in unique comorbid associations of specific AUDs and DUDs with specific psychiatric disorders.

CONCLUSIONS

Rates of psychiatric disorders comorbid with AUDs and DUDs indicate large burdens of morbidity in both sexes, highlighting the need for careful assessment and appropriate treatment of both substance use and mental health disorders. The unique comorbid associations with AUDs and DUDs identified in this study further indicate the need for prospective etiological research to characterize these associations, their underlying mechanisms, and the possible sex specificity of those mechanisms.

Association between immigrant status and history of compulsory treatment in a national sample of individuals assessed for drug use disorders through the Swedish public welfare system

In-person interview data from 13,903 individuals assessed for a drug use disorder in the Swedish welfare system from 2002-2008, were analyzed using logistic regression methods. Second generation immigrants with non-Scandinavian parents were 41% more likely to report a history of compulsory treatment compared to those born in Sweden to Swedish parents after controlling for age, gender, education, mental health treatment homeless status history, and criminal justice history. Implications include the need to study acculturation, stigma, and discrimination-related factors as well as to promote culturally competent outreach to immigrant populations.

Stability of Outcomes Following Residential Drug Treatment For Patients with Co-occurring Disorders

OBJECTIVE: Few studies have examined the stability of both substance use and mental health outcomes following residential drug abuse treatment for individuals with co-occurring disorders (COD). This study examines outcomes at 6 and 12 months for individuals with COD, in relationship to services received over the follow-up period. METHODS: Participants with COD (N=310) were sampled from 11 residential drug abuse treatment programs and completed in-depth assessments within 30 days of intake and at 6- and 12-month follow-ups. A path model was developed testing the relationships among treatment participation and services received, psychological status, and substance use outcomes across the two follow-up points. RESULTS: Retention for at least 90 days in residential drug treatment was associated with less inpatient mental health treatment and more mental health services received at 6 months; outpatient mental health treatment was associated with reduced substance use at 6 months. Substance use at 6 months was associated with more psychological distress at both 6 and 12 months and more inpatient mental health treatment at 12 months. CONCLUSIONS: Findings suggest that receipt of mental health services following residential drug abuse treatment for patients with COD is critical to improving their longer-term outcomes.

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.

Gender differences in sense of coherence, perceived social support, and negative emotions among drug-abstinent israeli inmates

This study examines gender differences in the sense of coherence, perceived social support, and negative emotions among drug-abstinent Israeli inmates. One hundred nineteen inmates have participated in this study (65 men and 54 women). The findings indicate that among female inmates, abstinence of more than a year is related to a decrease in sense of coherence and to an increase in their perceived friend support. In contrast, among male inmates, abstinence of more than a year is related to an increase in sense of coherence and no change at all in their perceived friend support. In addition, hostility level is lower and sense of coherence is higher when the length of abstinence exceeds a year among male inmates. In contrast, among female inmates hostility level is higher when the sense of coherence is lower, without any connection to the length of abstinence. The implications of these findings to treatment intervention are discussed.

Substance use disorders and treatment utilization among MDMA users: Results from The National Epidemiologic Survey on Alcohol and Related Conditions

The study examined the prevalence and correlates of substance use disorders and treatment utilization among lifetime MDMA users. Secondary analyses were conducted on data from the 2001-2002 NESARC, a nationally representative survey of adults in the United States. Lifetime MDMA use was assessed, and MDMA users (n = 562) were compared to a matched sample of non-MDMA users. Substance use diagnoses were made using the AUDADIS - DSM-IV, and data on treatment utilization were collected. MDMA use was significantly related to lifetime and past year substance use disorders as well as treatment utilization in bivariate analyses. Multivariate analysis, however, showed that MDMA use was not related to lifetime substance use diagnosis or to treatment utilization. MDMA use still had the strongest association with past year substance use disorders.

Gender differences in interpersonal problems of alcohol-dependent patients and healthy controls

Alcohol dependence is a heavy burden on patients, their families, and society. Epidemiological studies indicate that alcohol dependence will affect many individuals at some time in their lives, with men affected more frequently than women. Since alcohol-dependent patients often exhibit a lack of social skills and suffer from interpersonal problems, the aim of this study is to elucidate whether men and women experience the same interpersonal problems. Eighty-five alcohol-dependent patients (48 men; 37 women) after detoxification and 62 healthy controls (35 men; 27 women) were recruited. Interpersonal problems were measured with the Inventory of Interpersonal Problems (IIP-64). Additionally, alcohol-dependent patients were interviewed with the Alcohol Use Disorders Identification Test (AUDIT) and were subtyped according to Lesch’s Alcohol Typology (LAT). There were no significant gender differences in the AUDIT and LAT between alcohol-dependent men and women. Interpersonal problems of alcohol-dependent men differed significantly in one out of eight dimensions from controls; alcohol-dependent men perceive themselves as colder than male controls. Alcohol-dependent women differed in four out of eight interpersonal dimensions from female controls. Alcohol-dependent women rated themselves as significantly more vindictive, more introverted, more overly accommodating and more intrusive than female controls. Results suggest that alcohol-dependent men and women suffer from different interpersonal problems and furthermore alcohol-dependent women perceive more interpersonal problems, whereas the severity of alcohol dependence did not differ between the groups. Our findings indicate that alcohol-dependent women may profit more from a gender-specific treatment approach aimed at improving treatment outcome than alcohol-dependent men.

Disparities in use of mental health and substance abuse services by persons with co-occurring disorders

OBJECTIVES

Individuals with co-occurring mental and substance use disorders require psychiatric and substance abuse treatments. A critical question is whether these individuals are treated for both disorders.

METHODS

This study prospectively examined 24-month service utilization patterns of 224 persons with co-occurring disorders who were recruited from crisis residential programs in the mental health treatment system (N=106) and from crisis residential detoxification programs in the substance abuse treatment system (N=118) in San Francisco. Utilization data were collected from the billing-information systems of both treatment systems. Demographic and clinical data were obtained in interviews with participants. Data were analyzed for group differences with chi square tests and logistic, linear, and zero-truncated negative binomial regression.

RESULTS

After the analyses controlled for demographic and clinical factors, participants recruited from the substance abuse treatment system were less likely than those from the mental health treatment system to obtain any mental health services, mental health day treatment, transitional residential care, case management, and other outpatient services (p<.001 for all comparisons). They were more likely to obtain crisis residential detoxification (p=.003), had more days of drug residential treatment (p=.028), but received fewer hours of outpatient services (p=.012).

CONCLUSIONS

There were disparities in patterns of service utilization, although there were no significant diagnostic differences between the two groups. These findings should be valuable in considering systems development and modification. Furthermore, they can contribute to research about factors that underlie results. Study replications should be conducted to assess the robustness of these findings in other locales.

12-step participation among dually-diagnosed individuals: a review of individual and contextual factors

The frequent co-occurrence of substance abuse disorders along with psychiatric disorders creates a number of complexities and needs in terms of long-term treatment for individuals. 12-step groups might provide unique mechanisms by which dually-diagnosed individuals can maintain their abstinence and improve their psychological functioning. This paper reviews the literature on outpatient community 12-step participation among dually-diagnosed individuals, and also focuses on individual factors that may interact with treatment: homelessness, legal status, and ethnicity. A total of 59 articles was included in the review, with an emphasis on these individual factors and findings regarding mechanisms of action. Overall, findings from the studies reviewed suggest a general benefit of 12-step participation across these individual factors and some potential for dual-focus 12-step programs for dually-diagnosed individuals via social support and self-efficacy. However, methodological limitations and lack of research in the area of ethnicity limited some of the conclusions that can be made. Suggestions for further research are discussed.

Association of personality disorders, family conflicts and treatment with quality of life in opiate addiction

AIM

The purpose of this study was to investigate the association of the current status and longitudinal changes in different clinical and social variables with quality of life (QOL) in opiate addiction. Our hypotheses were that drug use, comorbid personality disorders and social problems are associated with worse QOL.

METHODS

107 participants with long-term opiate addiction were included and interviewed at entry with the Europ-ASI and the PDQ-R. QOL (SF-36) and changes in different domains of the Europ-ASI were assessed after 2 years.

RESULTS

Personality disorders, interpersonal conflicts with the family or partner and ongoing need for somatic and psychiatric treatment were significantly associated with worse subjective QOL, whereas changes in drug and alcohol use, the economic situation, legal problems and social problems with persons outside of the family showed no relevant association with QOL.

CONCLUSION

Our results provide support for an emphasis in treatment on helping clients to reduce intra- and interpersonal conflicts according to comorbid conditions and among family members and partnerships. In addition, the present data provide further support for the advantages of extended interventions in long-term opiate addiction.

Role of social support and self-efficacy in treatment outcomes among clients with co-occurring disorders

Individuals with co-occurring substance use and psychiatric disorders have a more severe clinical course and poorer outcomes than do individuals with one disorder. In an attempt to find intervening variables that may contribute to improvement in treatment outcomes among individuals with co-occurring disorders, we investigated the roles of social support and self-efficacy in a sample of 351 clients with co-occurring disorders in residential drug abuse treatment programs (53% male; 35% African American, 13% Hispanic). Given their demographic variability, we also explored how ethnicity and age influence self-efficacy and access to social support, as well as their relationships to the outcomes. Structural equation modeling was used to examine the impact of the demographics and baseline psychological status, substance use, social support, and self-efficacy on mental health and substance use outcomes 6 months after treatment entry. Time in treatment was included as a control. Greater social support at baseline predicted better mental health status and less heroin and cocaine use; greater self-efficacy predicted less alcohol and cocaine use. Older clients reported less social support. African-American ethnicity was associated with more cocaine use at baseline and follow-up; however, African Americans reported more self-efficacy, which moderated their cocaine use. The current study highlights the potential therapeutic importance of clients' personal resources, even among a sample of severely impaired individuals.

The impact of early trauma and abuse on residential substance abuse treatment outcomes for women

This study examines the impact of early abuse on the functioning and the 12-month treatment outcomes of 146 homeless addicted women who entered residential substance abuse treatment. Sixty-nine percent of the women reported exposure to childhood physical, sexual, or emotional abuse; the majority reported multiple forms of abuse. Comparisons of abused and nonabused women revealed significant differences in childhood, adolescent, and adult functioning, indicative of the pervasive detrimental effects of early abuse. Female survivors of childhood abuse did not improve in treatment as much as their nonabused peers in psychological functioning (p < .001), substance abuse (p < .01), or continuing trauma exposure (p < .01) . The findings suggest the importance of adapting models of residential substance abuse treatment to address concurrent issues related to trauma history. Additional research is needed to identify effective integrated treatment approaches for this population and to explore the independent and interconnected pathways linking trauma history and outcome.

Regardless of psychiatric severity the addition of contingency management to standard treatment improves retention and drug use outcomes

The relationship between psychiatric severity and substance use disorders treatment outcome was assessed in 393 individuals who received either standard treatment or standard treatment plus contingency management. The sample was divided into groups of low, moderate, and high psychiatric severity based upon baseline Addiction Severity Index psychiatric composite scores. Participants in the high psychiatric severity group reported a greater prevalence of psychiatric hospitalization, psychiatric medications, and suicide attempts, as well as poorer baseline psychosocial functioning. In terms of treatment outcome, a significant interaction between psychiatric severity and treatment modality was found in relation to treatment retention. Participants in the standard treatment condition were more likely to dropout of treatment earlier as psychiatric severity increased, while retention was similar across the psychiatric severity groups in the contingency management condition. Psychiatric severity was not linked to longest duration of abstinence achieved during treatment or adherence with contingency management procedures. Overall, these findings suggest contingency management is an efficacious and appropriate intervention for substance use disordered individuals across a range of psychiatric problems.

Health-related quality of life in French people living with HIV in 2003: results from the national ANRS-EN12-VESPA Study

OBJECTIVE

Since the advent of HAART, the assessment of health-related quality of life (HRQL) has become a major concern in the therapeutic follow-up of people living with HIV.

DESIGN

HRQL was evaluated for 2235 participants in the ANRS-EN12-VESPA Study. These participants completed the Medical Outcome Study 36-Item Short Form Health Survey (MOS SF-36) questionnaire. Anxiety and depression were assessed using the Hospital Anxiety and Depression (HAD) scale. Individuals were considered to have an 'acceptable' physical (and mental) HRQL if their MOS SF-36 scores were greater than the 25 percentile of the corresponding age-sex-specific distribution of scores in the French general population.

METHODS

Logistic regression models were used to identify factors associated with an 'acceptable' physical and mental HRQL among demographic, psychosocial and clinical characteristics. Potential selection bias caused by non-random missing responses to the MOS SF-36 questionnaire was statistically tested.

RESULTS

Physical and mental HRQL were 'acceptable' in 1176 (53%) and 1152 (51%) individuals, respectively. After adjusting for sociodemographic factors, HIV clinical status and hepatitis C co-infection, high HAD scores and the consumption of anxiolytic, antidepressant and hypnotic drugs were found to be negatively associated with normal physical and mental HRQL.

CONCLUSION

The role of disclosure and discrimination is determinant in HRQL, and the various cultural and psychological dimensions require further research. The presence of other infections or co-morbidities requires a comprehensive care system including medical staff and social worker teams. HIV should increasingly be regarded as a chronic disease characterized by different pathological conditions requiring a comprehensive and multidisciplinary approach.

Impact of program services on treatment outcomes of patients with comorbid mental and substance use disorders

OBJECTIVE

This study examined the outcomes of individuals with co-occurring disorders who received drug treatment in programs that varied in their integration of mental health services. Patients treated in programs that provided more on-site mental health services and had staff with specialized training were expected to report less substance use and better psychological outcomes at follow-up.

METHODS

Participants with co-occurring disorders were sampled from 11 residential drug abuse treatment programs for adults in Los Angeles County. In-depth assessments of 351 patients were conducted at treatment entry and at follow-up six months later. Surveys conducted with program administrators provided information on program characteristics. Latent variable structural equation models revealed relationships of patient characteristics and program services with drug use and psychological functioning at follow-up.

RESULTS

Individuals treated in programs that provided specific dual diagnosis services subsequently had higher rates of utilizing mental health services over six months and, in turn, showed significantly greater improvements in psychological functioning (as measured by the Brief Symptom Inventory and the RAND Health Survey 36-item short form) at follow-up. More use of psychological services was also associated with less heroin use at follow-up. African Americans reported poorer levels of psychological functioning than others at both time points and were less likely to be treated in programs that provided mental health services.

CONCLUSIONS

Study findings support continued efforts to provide specialized services for individuals with co-occurring disorders within substance abuse treatment programs as well as the need to address additional barriers to obtaining these services among African Americans.

Treatment services and service delivery models for dually diagnosed clients: variations across mental health and substance abuse providers

This paper reports on a survey of administrators (n = 26) and staff (n = 248) in 10 mental health and 16 substance abuse programs in Los Angeles County providing services to individuals with co-occurring disorders. Although half or more of the administrators and staff reported that their programs had some degree of on-site service integration, there was a lack of agreement within most programs as to the extent of integration. Characteristics of services provided and interactions with other service providers are also examined. Future research is needed regarding the divergent perceptions of administrators and staff and their relationship to treatment outcomes.

The duration and correlates of addiction and treatment careers

While addiction is increasingly recognized as a chronic condition, little information is available on the actual duration of addiction and treatment careers. The purpose of this study was to estimate the duration and correlates of years between (a) first use and at least a year of abstinence and (b) first treatment admission and at least one year of abstinence. Data are from 1,271 of 1,326 (96%) people recruited from a stratified sequential sample of admissions to publicly funded treatment programs in a large metropolitan area. Participants were interviewed at 6, 18, 24, 36, 48, and 60 months post-intake. With an average age at the referent intake of 35 (SD = 8) years, the sample is 59% female, 87% African American, 7% Hispanic, and 5% white. The most common dependence diagnoses were for cocaine (64%), alcohol (44%), opioids (41%), and/or marijuana (14%). Using lifetime substance use and treatment histories collected at intake and subsequent treatment utilization recorded during follow-up interviews, we conducted survival analysis to estimate the time from first use and first treatment until people reported 12 months of abstinence or died (with people still using, in treatment, or dead at the last follow-up treated as right censored). During the three years after intake, 47% reached at least 12 months of abstinence. The median time from first to last use was 27 years. The median time from first treatment episode to last use was 9 years. Years to recovery were significantly longer for males, people starting use under the age of 21 (particularly those starting under the age of 15), people who had participated in treatment 3 or more times, and for people high in mental distress. The exploratory results suggest that multiple episodes of care over several years are the norm and that rather than thinking of multiple episodes in terms of "cumulative dosage," it might be better thought of as further evidence of chronicity and that we need to develop and evaluate models of longer term recovery management.
