Drug treatment outcomes: investigating the long-term effects of sexual and physical abuse histories

Prevalence of adult sexual abuse in men with mental illness: Bayesian meta-analysis

BACKGROUND

Sexual abuse is a broad category of traumatic experiences that includes rape and any unwanted sexual contact with a body part or foreign object, whether penetrative, oral or otherwise. Although patients with mental illness have a higher risk of becoming victims of sexual abuse in adulthood, few studies investigate the proportion of male victims in this population. Their underrepresentation in research is a barrier to understanding the negative outcomes associated with sexual abuse in men.

AIMS

We estimated the prevalence of recent (past year) and adulthood sexual abuse perpetrated by any perpetrator and separately by intimate partners in males diagnosed with a mental illness.

METHOD

To model the prevalences and heterogeneity arising from reports, we used Bayesian multilevel models. Prevalences were estimated for mixed-diagnosis, substance misuse, intellectual disability and post-traumatic stress disorder samples, and studies reporting specifically on intimate partner violence. This review was registered through PROSPERO (CRD42020169299).

RESULTS

Estimated adult sexual abuse was 5.3% (95% Credibility Interval 1.6-12.8%) for past-year abuse and 14.1% (95% Credibility Interval 7.3-22.4%) for abuse in adulthood. There was considerable heterogeneity of prevalence between studies and diagnosis groups.

CONCLUSIONS

Our analyses show that the prevalence of sexual abuse of males diagnosed with a mental illness was much higher than for men in the general population. This has important implications regarding the proportion of undetected or untreated sexually abused men in clinical practice.

Polysubstance abuse among sexually abused in alcohol, drug, and gambling addiction treatment in Greenland: a cross sectional study

This study aims to investigate the association between earlier sexual abuse and polysubstance abuse among persons in alcohol, drug and gambling addiction treatment in Greenland. The study included 431 individuals treated in 2017–2019. Data on exposure (sexual abuse), outcome (polysubstance abuse), and potential confounders (age, sex, school education, further education, labour market affiliation, physical abuse and emotional abuse) were extracted from The National Database on Substance Abuse Treatment. Polysubstance abuse was defined as both smoking cannabis more than once a week and having an AUDIT score >15. Logistic regression was used to estimate odds ratios (ORs). In total, 61% reported having been sexually abused. Women were more often sexually abused and had more often been physically and emotionally abused when compared to men. Polysubstance abuse (OR 2.06, 95% CI: 1.22; 3.48) and cannabis abuse (OR 1.89, 95% CI: 1.20; 2.98), but not alcohol abuse, were more frequent in sexually abused when compared to non-victims of sexual abuse. This study found polysubstance abuse to be more frequent in sexually abused treatment seekers. It is recommended that the findings are taken into account in the planning of treatment services and in training of counsellors.

Re-traumatization Cycle: Sexual Abuse, Post-Traumatic Stress Disorder and Sexual Risk Behaviors among Club Drug Users

Background: Club drug users are high risk and vulnerable population for adverse drug-related consequences and sexual risk behaviors. Few investigations have addressed the possible interrelationship between early trauma and PTSD among young club drug using populations. Objective: Exposure to traumatic experiences - especially in childhood, has been linked to risk behaviors exposure and substance use disorder. This study aimed to assess and compare drug use patterns and the presence of childhood sexual abuse (CSA) experiences among ecstasy and LSD users with and without Posttraumatic Stress Disorder (PTSD). Method: This cross-sectional study employed targeted sampling and ethnographic mapping approaches via face-to-face interviews conducted at bars and electronic music festivals. The Global Appraisal of Individual Needs questionnaire was used as the primary assessment instrument. Participants were from 18 to 39 years of age, had used ecstasy and/or LSD in the 90 days prior to the interview, and were not in treatment for alcohol and other drug problems. Results: Out of the 240 participants, 123 (51.2%) presented PTSD symptoms. Those presenting PTSD were younger, less educated, with lower income, and presented higher drug use severity than those without PTSD symptoms. Moreover, a higher prevalence of sexual risk behavior was verified among those with PTSD. There was an association between PTSD symptoms and CSA history, where 64.2% of individuals with PTSD also presented CSA, compared to 47% among those without PTSD (p = .028). Individuals with co-occurring history of CSA and PTSD symptoms reported earlier use of ecstasy, LSD, and cocaine compared to individuals with a history of CSA but without PTSD. Conclusions: In the present study, participants with a history of PTSD demonstrate a history of CSA, as well as pronounced severity in several areas - precocity of use, severity of addiction, and greater exposure to situations of sexual risk. Thus, a cycle of traumatization may be established through early potential trauma, which can remain unprocessed and contribute to earlier and more severe substance use and sexual risk behaviors. Identification of PTSD symptoms and risk for HIV and other STIs among young club drug users is critical to address focused treatment approaches for this vulnerable population.

Puerto Rican Drug Users' Experiences of Physical and Sexual Abuse

This study examines gender and developmental stage differences in physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 799 participants in New York and 382 in Puerto Rico. Qualitative data were collected through in-depth life histories with 21 participants. Study participants included 297 female and 884 male Puerto Rican drug injectors and crack smokers. Females were significantly more likely than males to report physical abuse by a family member in childhood and unwanted sex in childhood, adolescence, and adulthood. Qualitative findings describe abuse in the contexts of family, drug dealing, drug paraphernalia possession, and sex work.

Gender-specific predictors of retention and opioid abstinence during methadone maintenance treatment

AIMS

Retention in methadone maintenance treatment (MMT) for 1 year is associated with positive outcomes including opioid abstinence, however, most studies have not investigated gender differences. We hypothesized that predictors of retention and opioid abstinence would differ between men and women, and aimed to determine which factors best predict retention and abstinence for each gender.

METHODS

Data were available for 290 patients (173 M, 117 F) admitted to outpatient MMT. Regression analyses, stratified by gender, were conducted to identify unique predictors of MMT retention (<1 vs. >1 year) and opioid abstinence rate (proportion of opioid-free urine samples up to 1 year retention).

RESULTS

Gender did not significantly predict treatment retention (mean = 231 days, 39% retained > 1 year) or opioid abstinence (49% overall). For males, significant predictors of > 1-year retention were urine samples negative for opioids (odds ratio [OR] = 6.67) and cannabinoids (OR = 5.00) during the first month, and not cocaine dependent (OR = 2.70). Significant predictors of higher long-term opioid abstinence were first-month urine samples negative for opioids and cocaine metabolites. For females, significant predictors of >1-year retention were first-month urine samples negative for cocaine metabolites (OR = 4.00) and cannabinoids (OR = 9.26), and no history of sexual victimization (OR = 3.03). The only significant predictor of higher opioid abstinence rate was first-month opioid-free urine samples.

CONCLUSIONS

These findings indicate gender-specific predictors of MMT retention and opioid abstinence. Future studies on MMT outcomes should examine each gender separately, and consider unique pathways by which females and males adhere to, and benefit from MMT.

Stress modulates illness-course of substance use disorders: a translational review

Childhood trauma and post-childhood chronic/repeated stress could increase the risk of a substance use disorder by affecting five stages of addiction illness-course: (a) initial experimentation with substances; (b) shifting from experimental to regular use; (c) escalation from regular use to abuse or dependence; (d) motivation to quit; and (e) risk of (re-)lapse. We reviewed the human literature on relationships between stress and addiction illness-course. We explored per illness-course stage: (i) whether childhood trauma and post-childhood chronic/repeated stress have comparable effects and (ii) whether effects cut across classes of substances of abuse. We further discuss potential underlying mechanisms by which stressors may affect illness-course stages for which we relied on evidence from studies in animals and humans. Stress and substances of abuse both activate stress and dopaminergic motivation systems, and childhood trauma and post-childhood stressful events are more chronic and occur more frequently in people who use substances. Stressors increase risk to initiate early use potentially by affecting trait-like factors of risk-taking, decision making, and behavioral control. Stressors also accelerate transition to regular use potentially due to prior effects of stress on sensitization of dopaminergic motivation systems, cross-sensitizing with substances of abuse, especially in people with high trait impulsivity who are more prone to sensitization. Finally, stressors increase risk for abuse and dependence, attenuate motivation to quit, and increase relapse risk potentially by intensified sensitization of motivational systems, by a shift from positive to negative reinforcement due to sensitization of the amygdala by corticotropin releasing factor, and by increased sensitization of noradrenergic systems. Stress generally affects addiction illness-course across stressor types and across classes of substances of abuse.

Two-Year Outcomes of Treatment for Methamphetamine Use

While evaluation research supports the general effectiveness of substance abuse treatment, there is not a comprehensive literature on treatment effectiveness for methamphetamine (MA) use. The authors consider three outcome measures--MA use, criminal activity, and employment--compared across three periods: 24-months pretreatment, during treatment, and 24-months post-treatment. Data are from an intensive natural history interview conducted two to three years after treatment for 349 randomly selected admissions to treatment for MA abuse in a large publicly-funded county treatment system. Through this naturalistic design, data provide a system-wide perspective on effectiveness of treatment as usual. Results showed reduction in MA use and crime during and following treatment and increased employment following treatment over pretreatment levels. Regression analyses showed higher levels of education and more time in treatment related to more positive post-treatment outcomes for all three measures. Lower percentage of post-treatment months with MA use also was related to more pretreatment MA-related problems, lower pretreatment MA use, and residential (compared to outpatient) treatment modality. Lower post-treatment criminal activity was also related to gender (being female), lower pretreatment criminal activity, and residential modality. Higher percentage of post-treatment months with employment also was related to gender (being male), ethnicity (not African-American), and higher pretreatment employment.

The Impact of Comprehensive Services in Substance Abuse Treatment for Women With a History of Intimate Partner Violence

This study examines the impact of comprehensive services on posttreatment substance use among women with a history of intimate partner violence. The sample includes 1,123 women from 50 treatment facilities derived from the National Treatment Improvement Evaluation Study (NTIES). Generalized linear mixed modeling was used to determine whether a history of intimate partner violence moderates the association between service receipt and posttreatment substance use. Significant interactions were found between history of intimate partner violence and concrete ( p = .016) and family services ( p = .023) in predicting substance use.

History of reported sexual or physical abuse among long-term heroin users and their response to substitution treatment

Opioid-dependent individuals with a history of abuse have exhibited worse mental and physical health compared to those without such a history; however, the evidence regarding the influence of abuse histories on addiction treatment outcomes are conflicting. In the present study, we identified history of physical or sexual abuse at treatment initiation in relation to drug use and health among long-term opioid-dependent individuals and we determined the relationship of abuse histories with treatment outcomes following substitution treatment. We analyzed data from a randomized controlled trial that compared the effectiveness of opioid-agonists in the treatment of chronic opioid dependence. The North American Opiate Medication Initiative (NAOMI) was conducted in Vancouver and Montreal (Canada) and provided oral methadone, injectable diacetylmorphine or injectable hydromorphone, the last two on a double blind basis, over 12 months. A total of 112 (44.6%) participants reported a history of physical or sexual abuse at baseline. Participants with an abuse history reported a significantly higher number of chronic medical problems, suicide attempts, and previous drug treatments and had poorer psychiatric, family and social relations, and quality of life status compared to those without abuse histories. No differences in current and past substance use were found between those with and without abuse histories. Following 12 months of treatment, the participants with abuse histories improved to a similar degree as those without a history of abuse in all of the European Addiction Severity Index sub-scales, with the exception of medical status. The findings suggest that individuals with abuse histories were able to achieve similar outcomes as those without abuse histories following treatment despite having poorer scores in physical and mental health, social status and quality of life at treatment initiation. These findings suggest that the substitution treatments as provided in this study can benefit the most vulnerable and access needs to be expanded to reach this population.

Sexual abuse and lifetime diagnosis of psychiatric disorders: systematic review and meta-analysis

OBJECTIVE

To systematically assess the evidence for an association between sexual abuse and a lifetime diagnosis of psychiatric disorders.

PATIENTS AND METHODS

We performed a comprehensive search (from January 1980-December 2008, all age groups, any language, any population) of 9 databases: MEDLINE, EMBASE, CINAHL, Current Contents, PsycINFO, ACP Journal Club, CCTR, CDSR, and DARE. Controlled vocabulary supplemented with keywords was used to define the concept areas of sexual abuse and psychiatric disorders and was limited to epidemiological studies. Six independent reviewers extracted descriptive, quality, and outcome data from eligible longitudinal studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled across studies by using the random-effects model. The I(2) statistic was used to assess heterogeneity.

RESULTS

The search yielded 37 eligible studies, 17 case-control and 20 cohort, with 3,162,318 participants. There was a statistically significant association between sexual abuse and a lifetime diagnosis of anxiety disorder (OR, 3.09; 95% CI, 2.43-3.94), depression (OR, 2.66; 95% CI, 2.14-3.30), eating disorders (OR, 2.72; 95% CI, 2.04-3.63), posttraumatic stress disorder (OR, 2.34; 95% CI, 1.59-3.43), sleep disorders (OR, 16.17; 95% CI, 2.06-126.76), and suicide attempts (OR, 4.14; 95% CI, 2.98-5.76). Associations persisted regardless of the victim's sex or the age at which abuse occurred. There was no statistically significant association between sexual abuse and a diagnosis of schizophrenia or somatoform disorders. No longitudinal studies that assessed bipolar disorder or obsessive-compulsive disorder were found. Associations between sexual abuse and depression, eating disorders, and posttraumatic stress disorder were strengthened by a history of rape.

CONCLUSION

A history of sexual abuse is associated with an increased risk of a lifetime diagnosis of multiple psychiatric disorders.

History of physical or sexual abuse and participation in 12-step self-help groups

OBJECTIVES

Although 12-step groups are an important resource for managing substance use problems, their efficacy for patients with a physical or sexual abuse history is unknown.

METHODS

In the present study, patients with a history of physical or sexual (n = 122) or no (n = 143) abuse were interviewed at entry to outpatient substance use treatment at the Veterans Administration.

RESULTS

After adjusting for baseline substance use, physical or sexual abuse was associated with more attendance at and involvement in 12-step groups. Participation in 12-step groups predicted abstinence at one year, regardless of abuse history.

CONCLUSIONS

Limitations and implications are discussed.

Lifetime physical and sexual abuse and substance use treatment outcomes in men

Although lifetime physical and sexual abuse are common among substance use disorder (SUD) patients, few studies have examined the impact of abuse on treatment outcomes, particularly for men. Men with lifetime physical (n = 49), sexual (n = 49), or no abuse (n = 117) history were assessed at entry to outpatient SUD treatment and at 6 and 12 months postintake. Men with a history of physical or sexual abuse had more severe drug problems at intake, but by 6 months, there were no group differences in drug use. However, relative to men without an abuse history, men with a sexual abuse history had more severe psychiatric problems at all three time points and were more likely to report significant suicidality at intake and 6 months. Findings suggest that men with a history of sexual abuse benefit from SUD treatment, but additional intervention may be warranted to remedy persisting psychiatric distress.

Substance abuse treatment entry, retention, and outcome in women: a review of the literature

This paper reviews the literature examining characteristics associated with treatment outcome in women with substance use disorders. A search of the English language literature from 1975 to 2005 using Medline and PsycInfo databases found 280 relevant articles. Ninety percent of the studies investigating gender differences in substance abuse treatment outcomes were published since 1990, and of those, over 40% were published since the year 2000. Only 11.8% of these studies were randomized clinical trials. A convergence of evidence suggests that women with substance use disorders are less likely, over the lifetime, to enter treatment compared to their male counterparts. Once in treatment, however, gender is not a significant predictor of treatment retention, completion, or outcome. Gender-specific predictors of outcome do exist, however, and individual characteristics and treatment approaches can differentially affect outcomes by gender. While women-only treatment is not necessarily more effective than mixed-gender treatment, some greater effectiveness has been demonstrated by treatments that address problems more common to substance-abusing women or that are designed for specific subgroups of this population. There is a need to develop and test effective treatments for specific subgroups such as older women with substance use disorders, as well as those with co-occurring substance use and psychiatric disorders such as eating disorders. Future research on effectiveness and cost-effectiveness of gender-specific versus standard treatments, as well as identification of the characteristics of women and men who can benefit from mixed-gender versus single-gender treatments, would advance the field.

Criminality among female drug users following an HIV risk-reduction intervention

The main objectives of this article are to determine the prevalence of criminality among a sample of female African American drug users and to examine change in criminality over time, including the correlates associated with this change. Data were collected from 336 adult women who participated in an HIV risk-reduction intervention focused on the context of the women's daily life. Face-to-face structured interviews were conducted at baseline, prior to enrolling in the intervention, and at follow-up, 6 months after completion of the intervention. Bivariate and correlated multivariate methods were utilized to examine changes in criminality and other behaviors over time. Both violent and nonviolent criminality declined significantly between baseline and follow-up assessments. Of the correlates considered, drug-using characteristics and victimization played the greatest role in explaining the decrease in criminality. Low self-control and depressive symptoms also contributed to the reduction in criminality. The findings suggest the importance of considering individual characteristics that may influence the women's criminal behavior as well as the impact of their routine activities.

Using focus groups to investigate the educational needs of female injecting heroin users in Taiwan in relation to HIV/AIDS prevention

This study investigated educational needs of female injecting heroin users in Taiwan relating to HIV/AIDS prevention via six focus group discussions in a prison. All sessions were audio-taped with respondents' consent and the discussions transcribed verbatim. The findings indicated that respondents had adequate knowledge about HIV/AIDS, but held misconceptions regarding the modes of HIV transmission. Many respondents who did not perceive themselves susceptible to AIDS rarely used condoms and occasionally shared needles. Stigma surrounding AIDS is pervasive among respondents and they considered contracting cancer would be preferable to having AIDS; the latter could precipitate suicide. Lastly, many respondents had no confidence in assurances of confidentiality regarding HIV testing. Issues of misconceptions, high-risk behaviors, stigma surrounding AIDS and confidentiality of HIV testing must be addressed in appropriate HIV/AIDS education programmes with respect to the needs of female injecting heroin users.

Sexual abuse history and treatment outcomes among women undergoing methadone treatment

Women entering drug abuse treatment programs who report a history of sexual abuse are also likely to report poorer psychosocial functioning, more drug-related problems, and more family-of-origin problems. This study investigates outcome differences at follow-up between women with and those without sexual abuse histories who were treated at an outpatient methadone treatment program. Follow-up interviews were conducted with 98 women, 40% of whom reported prior sexual abuse. Those with a history of sexual abuse who reported problems at intake with psychosocial functioning and family support continued to report such problems at follow-up as compared with the women without a history of sexual abuse. However, no difference was found at follow-up between women with and those without sexual abuse histories in terms of drug use, employment, criminality, or HIV-risky behaviors. The findings suggest that sexual abuse history alone cannot predict treatment outcomes for women in methadone treatment. The implications of these findings are discussed in terms of treatment process and services.

Prevalence of physical and sexual abuse among substance abuse patients and impact on treatment outcomes

More than half of substance abusers entering addiction treatment report a history of physical or sexual abuse. It is unclear if such a history impacts treatment outcomes. This one-year follow-up study of 700 substance abusers sought to clarify the relationship between lifetime physical and/or sexual abuse and addiction treatment outcome to help address the specific needs of this population. To achieve this goal, baseline characteristics, no-show for treatment status, post-treatment clinical outcomes, and treatment history were studied for subjects with lifetime history of abuse (47.3%) versus without. Abused subjects, predominantly women, were significantly more impaired at baseline on clinical dimensions including family/social severity and psychiatric severity as measured by the Addiction Severity Index (ASI), and general level of functioning. The two groups endorsed different drugs as primary, with the abused group less frequently endorsing heroin and cocaine in favor of alcohol and polydrug use. Abused subjects reported more prior medical and psychiatric treatments. Abuse history was not a predictor of no-show for treatment. Over the 1-year follow-up, lifetime physical and/or sexual abuse was significantly associated with worse psychiatric status and more psychiatric hospitalizations and outpatient treatment despite receiving similar intensive addiction treatment.

Childhood sexual abuse patterns, psychosocial correlates, and treatment outcomes among adults in drug abuse treatment

This study reports on the effects of having a history of childhood sexual abuse (CSA) on treatment outcomes among substance abusing men and women (N = 2,434) in a national, multisite study of drug treatment outcomes. A history of CSA was reported by 27.2% of the women and 9.2% of the men. Controlling for gender, compared to patients without CSA, patients reporting CSA were younger at entry into the current drug treatment, were more likely to be White, were more likely to have a comorbid mental disorder, be alcohol or cocaine dependent, had higher levels of criminal activities, had a higher level of problem recognition, and had a more negative peer influence. Controlling for these correlates, a history of abuse was related to a lower likelihood of posttreatment abstinence.

Factors related to childhood sexual abuse among gay/bisexual male Internet escorts

This exploratory investigation examined the relationship between childhood sexual abuse (CSA) and related psychosocial characteristics and sexual behaviors among 46 gay/bisexual male escorts who advertise via the Internet. More than a quarter of men (28.3%) reported some history of CSA. Men reporting CSA were more likely to be from an ethnic minority group, identify as bisexual, have a primary male partner, and were less likely to identify an anal receptive ("bottom") sexual role preference. Men with a history of CSA were more likely to report unprotected sex with work-related partners, increased internalized homophobia, and decreased adolescent isolation. Interventions designed for male escorts with a history of CSA should emphasize safer sex strategies with work partners and reducing internalized homophobia.

Gender differences in outcomes from prison-based residential treatment

This study examines gender similarities and differences in background characteristics, the effectiveness of treatment, and the predictors of post-release outcomes among incarcerated drug-using offenders. The sample of 1,842 male and 473 female treatment and comparison subjects came from a multi-site evaluation of prison-based substance abuse treatment programs. Three-year follow-up data for recidivism and post-release drug use were analyzed using survival analysis methods. Despite the greater number of life problems among women than men, women had lower three-year recidivism rates and rates of post-release drug use than did men. For both men and women, treated subjects had longer survival times than those who were not treated. There were both similarities and differences with respect to gender and the other predictors of the two post-release outcomes. Differences in background characteristics and in factors related to post-release outcomes for men and women suggest the plausibility of gender-specific paths in the recovery process.

Sexual abuse among women entering methadone treatment

Women who enter drug abuse treatment programs are likely to report histories of sexual abuse that may impact psychosocial functioning, retention, and outcomes. This study investigates differences at admission between women with and without sexual abuse histories who entered an outpatient methadone treatment program in Texas. In a sample of 137 women, 39% reported prior sexual abuse. Findings show that women with sexual abuse histories were more likely also to have experienced physical and emotional abuse, to report poorer family-of-origin relationships, and to report more drug-related problems. These clients also reported more depression, anxiety, thoughts of suicide, trouble concentrating, and trouble controlling violent behavior. Results are discussed in terms of the need for adequate assessment of abuse history at intake and the need for targeted outcome studies to better define the impact of past abuse on treatment participation and outcome.

Immigrant and native-born female heroin addicts in Israel

There are an estimated 25,000 heroin addicts in Israel and nearly one out of every five is a woman. Also, about one fourth of the addict population immigrated to Israel from the former Soviet Union (mostly from Russia and the Ukraine) since 1989. In this study, native born and immigrant female addicts were interviewed to develop an understanding of their background characteristics, patterns of drug use, and attitudes based on group status. Results show that the two groups of women are similar in many respects; however, differences do exist. Russian-speaking women tend to be better educated and have a greater concern about their personal health and maintaining custody of their children. Additionally, immigrant women are more inclined to use heroin and other substances while receiving treatment and are more likely to have a father who abuses alcohol. Discussion is given to the study findings as well as issues relevant to the formation of policy regarding services to female addicts in the country.
