Exploring the relationship between eating disorder symptoms and substance use severity in women with comorbid PTSD and substance use disorders.

BACKGROUND: Eating disorders (ED) and substance use disorders (SUD) commonly co-occur, especially in conjunction with posttraumatic stress disorder (PTSD), yet little is known about ED and ED symptoms in women presenting to addiction treatment programs. OBJECTIVE: We examined the association between ED symptoms and substance use frequency and severity in a sample of women with a DSM IV diagnosis of current SUD and PTSD enrolled in SUD treatment. METHOD: Participants were 122 women from four substance abuse treatment sites who participated in a multi-site clinical trial through the National Institute of Drug Abuse Clinical Trials Network (NIDA CTN). The Eating Disorder Examination-Questionnaire (EDE-Q), the Clinician's Administered PTSD Scale (CAPS) and the Addiction Severity Index (ASI) were administered at baseline and correlational analyses were performed. Variables that significantly correlated with EDE-Q total and subscale scores were entered into a linear regression analysis. RESULTS: Scores on the EDE-Q Global scale, as well as the Eating Concern, Weight Concern and Shape Concern subscales of the EDE-Q were significantly associated with Caucasian race/ethnicity, past 30 day opiate use, higher ASI Psychiatric Subscale score and lower ASI Employment Subscale score. CONCLUSION: Although exploratory, these findings suggest that there may be a relationship between addiction severity, use of certain drugs of abuse and eating disorder symptoms, particularly those involving weight and shape concerns in women with comorbid PTSD and SUD.

Intimate partner violence outcomes in women with PTSD and substance use: a secondary analysis of NIDA Clinical Trials Network "Women and Trauma" Multi-site Study.

Studies have shown strong associations between intimate partner violence (IPV) and both posttraumatic stress disorder (PTSD) and substance use disorders (SUD). Despite these linkages, research on the dual diagnosis of PTSD-SUD and its relationship to IPV is in an early stage, and little is known about how PTSD-SUD treatment might influence IPV outcomes. The current study is a secondary analysis of a larger NIDA Clinical Trials Network study exploring the effectiveness of two behavioral interventions for women with comorbid PTSD-SUD. Participants (n=288) were randomly assigned to Seeking Safety (SS), a cognitive-behavioral treatment that focuses on trauma and substance abuse symptoms, or to Women's Health Education, a psychoeducational group. Logistic regressions were used to examine how treatment condition, identified risk factors and their interactions were related to IPV. Results showed that participants who were abstinent at baseline were significantly less likely to experience IPV over the 12-month follow-up period, whereas participants living with someone with an alcohol problem were significantly more likely to experience IPV over follow-up. Findings also showed that at a trend level participants with recent interpersonal trauma at baseline and higher total of lifetime trauma exposures were more likely to report IPV during follow-up. Although there was no main effect for treatment condition, a significant interaction between treatment condition and baseline abstinence was found. Participants who were abstinent at baseline and in the SS condition were significantly less likely to report IPV over follow-up. These findings indicate that an integrated treatment for PTSD and SUD was associated with significantly better IPV outcomes for a subset of individuals. The possibility that women with PTSD-SUD may differentially benefit from SS has important clinical implications. Further research examining the intersection of PTSD, SUD and IPV, and the impact of treatment on a range of outcomes is needed.

Gender research in the National Institute on Drug Abuse National Treatment Clinical Trials Network: a summary of findings.

BACKGROUND: The National Institute of Drug Abuse's National Drug Abuse Treatment Clinical Trials Network (CTN) was established to foster translation of research into practice in substance abuse treatment settings. The CTN provides a unique opportunity to examine in multi-site, translational clinical trials, the outcomes of treatment interventions targeting vulnerable subgroups of women; the comparative effectiveness of gender-specific protocols to reduce risk behaviors; and gender differences in clinical outcomes. OBJECTIVES: To review gender-related findings from published CTN clinical trials and related studies from January 2000 to March 2010. METHODS: CTN studies were selected for review if they focused on treatment outcomes or services for special populations of women with substance use disorders (SUDs) including those with trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors; or implemented gender-specific protocols. The CTN has randomized 11,500 participants (41% women) across 200 clinics in 24 randomized controlled trials in community settings, of which 4 have been gender-specific. RESULTS: This article summarizes gender-related findings from CTN clinical trials and related studies, focusing on trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors. CONCLUSIONS: These published studies have expanded the evidence base regarding interventions for vulnerable groups of women with SUDs as well as gender-specific interventions to reduce HIV risk behaviors in substance-using men and women. The results also underscore the complexity of accounting for gender in the design of clinical trials and analysis of results. SCIENTIFIC SIGNIFICANCE: To fully understand the relevance of gender-specific moderators and mediators of outcome, it is essential that future translational studies adopt more sophisticated approaches to understanding and measuring gender-relevant factors and plan sample sizes that are adequate to support more nuanced analytic methods.

Survey of eating disorder symptoms among women in treatment for substance abuse.

A strong association between substance use disorders (SUDs) and eating disorders (EDs) in women has been established. Yet, little is known about the rates and impact of ED symptoms in women presenting to addiction treatment. The current investigation assessed the prevalence of ED symptoms and their effect on treatment outcomes in a sample of substance abusing women with co-occurring posttraumatic stress disorder (PTSD) enrolled in outpatient substance use programs. Participants were 122 women who participated in a multisite clinical trial comparing two behavioral treatments for co-occurring SUD and PTSD. The Eating Disorder Examination-self report, and measures of PTSD and SUD symptoms were administered at baseline, during treatment and at four follow-up points. Two subgroups emerged; those reporting binge eating in the 28 days prior to baseline (Binge group; n = 35) and those who reported no binge eating episodes (No Binge group; n = 87). Women in the Binge group endorsed significantly higher ED, PTSD, and depression symptoms at baseline than those in the No Binge group. Although all participants showed significant reductions in PTSD symptoms and improvements in abstinence rates during the study period, the improvements for the Binge group were significantly lower. These findings suggest that a subgroup of women with co-occurring PTSD and SUDs, who endorsed binge ED symptoms, responded differently to SUD/PTSD group treatment. Identification of ED symptoms among treatment-seeking women with SUDs may be an important element in tailoring interventions and enhancing treatment outcomes.

Depression and anger as risk factors underlying the relationship between maternal substance involvement and child abuse potential.

OBJECTIVE: This study examines how emotion regulation deficits in the area of anger arousal and reactivity are associated with child abuse potential in mothers with substance use and depressive disorders in order to identify targeted areas for prevention and treatment. METHODS: A sample of 152 urban mothers was interviewed on measures of substance use, diagnosis of depression, anger arousal and reactivity, and child abuse potential. RESULTS: Linear hierarchical regressions revealed that anger arousal and reactivity exceeded diagnostic and demographic variables in predicting maternal child abuse potential. Additionally, anger arousal and reactivity was found to be a partial mediator of the relationship between diagnostic category and child abuse potential. CONCLUSIONS: Findings are discussed in relation to a multifaceted model of child abuse potential which broadens the existing literature to include an examination of depression and emotion regulation in order to more fully understand how substance use and child abuse potential are linked. PRACTICE IMPLICATIONS: Models and approaches which help clients to manage and regulate difficult feeling states, specifically anger, could be helpful, and may be most readily applied in such populations.

Do treatment improvements in PTSD severity affect substance use outcomes? A secondary analysis from a randomized clinical trial in NIDA's Clinical Trials Network.

OBJECTIVE: The purpose of the analysis was to examine the temporal course of improvement in symptoms of posttraumatic stress disorder (PTSD) and substance use disorder among women in outpatient substance abuse treatment. METHOD: Participants were 353 women randomly assigned to 12 sessions of either trauma-focused or health education group treatment. PTSD and substance use assessments were conducted during treatment and posttreatment at 1 week and after 3, 6, and 12 months. A continuous Markov model was fit on four defined response categories (nonresponse, substance use response, PTSD response, or global response [improvement in both PTSD and substance use]) to investigate the temporal association between improvement in PTSD and substance use symptom severity during the study's treatment phase. A generalized linear model was applied to test this relationship over the follow-up period. RESULTS: Subjects exhibiting nonresponse, substance use response, or global response tended to maintain original classification; subjects exhibiting PTSD response were significantly more likely to transition to global response over time, indicating maintained PTSD improvement was associated with subsequent substance use improvement. Trauma-focused treatment was significantly more effective than health education in achieving substance use improvement, but only among those who were heavy substance users at baseline and had achieved significant PTSD reductions. CONCLUSIONS: PTSD severity reductions were more likely to be associated with substance use improvement, with minimal evidence of substance use symptom reduction improving PTSD symptoms. Results support the self-medication model of coping with PTSD symptoms and an empirical basis for integrated interventions for improved substance use outcomes in patients with severe symptoms.

The impact of trauma-focused group therapy upon HIV sexual risk behaviors in the NIDA Clinical Trials Network "Women and trauma" multi-site study.

Women in drug treatment struggle with co-occurring problems, including trauma and post-traumatic stress disorder (PTSD), which can heighten HIV risk. This study examines the impact of two group therapy interventions on reduction of unprotected sexual occasions (USO) among women with substance use disorders (SUD) and PTSD. Participants were 346 women recruited from and receiving treatment at six community-based drug treatment programs participating in NIDA's Clinical Trials Network. Participants were randomized to receive 12-sessions of either seeking safety (SS), a cognitive behavioral intervention for women with PTSD and SUD, or women's health education (WHE), an attention control psychoeducational group. Participants receiving SS who were at higher sexual risk (i.e., at least 12 USO per month) significantly reduced the number of USO over 12-month follow up compared to WHE. High risk women with co-occurring PTSD and addiction may benefit from treatment addressing coping skills and trauma to reduce HIV risk.

Substance use, childhood sexual abuse, and sexual risk behavior among women in methadone treatment.

BACKGROUND: Substance use and a history of childhood sexual abuse (CSA) are risk factors for unprotected sex among women, yet questions remain as to how their combined influence may differentially affect sexual risk. OBJECTIVE: The current study investigated how complex relationships among drug use and CSA may contribute to unprotected sexual occasions (USO). METHODS: A Generalized Linear Mixed Model was used to examine the interaction between current cocaine/stimulants and opioid use and CSA on number of USOs in a sample of 214 sexually active women in outpatient methadone maintenance treatment. RESULTS: For women with CSA, an increase in days of cocaine/stimulant use was associated with a significant increase in USOs. In contrast, an increase in days of opiate use was associated with a significant decrease in USOs. For the group of women who did not report CSA, there was a significant increase in USOs with increased opiate use. CONCLUSIONS: Findings indicate that CSA is related to unprotected sexual occasions depending on drug type and severity of use. SCIENTIFIC SIGNIFICANCE: Women with CSA using cocaine are at particularly high risk for having unprotected sex and should be specifically targeted for HIV prevention interventions.

Multisite randomized trial of behavioral interventions for women with co-occurring PTSD and substance use disorders.

The authors compared the effectiveness of the Seeking Safety group, cognitive-behavioral treatment for substance use disorder and posttraumatic stress disorder (PTSD), to an active comparison health education group (Women's Health Education [WHE]) within the National Institute on Drug Abuse's Clinical Trials Network. The authors randomized 353 women to receive 12 sessions of Seeking Safety (M = 6.2 sessions) or WHE (M = 6.0 sessions) with follow-up assessment 1 week and 3, 6, and 12 months posttreatment. Primary outcomes were the Clinician Administered PTSD Scale (CAPS), the PTSD Symptom Scale-Self Report (PSS-SR), and a substance use inventory (self-reported abstinence and percentage of days of use over 7 days). Intention-to-treat analysis showed large, clinically significant reductions in CAPS and PSS-SR symptoms (d = 1.94 and 1.12, respectively) but no reliable difference between conditions. Substance use outcomes were not significantly different over time between the two treatments and at follow-up showed no significant change from baseline. Study results do not favor Seeking Safety over WHE as an adjunct to substance use disorder treatment for women with PTSD and reflect considerable opportunity to improve clinical outcomes in community-based treatments for these co-occurring conditions.

Methodological Innovation to Increase the Utility and Efficiency of Psychotherapy Research for Patients with Co-occurring Mental Health and Substance Use Disorders.

Psychotherapy research with chronic and difficult-to-treat populations such as those with co-occurring mental health and addictive disorders can employ flexible research designs, which allow for a systematic, yet non-linear relationship between efficacy and effectiveness designs. Outcomes research can bypass the efficacy-effectiveness dichotomy through use of a hybrid model (Carroll & Rounsaville, 2003) conducted in the context of community treatment settings in collaboration with community providers. We present the case for using this methodological approach as a means of advancing psychotherapy research and practice, while translating and disseminating empirically supported treatments with more efficiency. A hybrid model study conducted within the National Institute on Drug Abuse's Clinical Trials Network illustrates the application. These findings inform new directions for future research.

Effectiveness of HIV/STD sexual risk reduction groups for women in substance abuse treatment programs: results of NIDA Clinical Trials Network Trial.

CONTEXT: Because drug-involved women are among the fastest growing groups with AIDS, sexual risk reduction intervention for them is a public health imperative. OBJECTIVE: To test effectiveness of HIV/STD safer sex skills building (SSB) groups for women in community drug treatment. DESIGN: Randomized trial of SSB versus standard HIV/STD Education (HE); assessments at baseline, 3 and 6 months. PARTICIPANTS: Women recruited from 12 methadone or psychosocial treatment programs in Clinical Trials Network of National Institute on Drug Abuse. Five hundred fifteen women with >or=1 unprotected vaginal or anal sex occasion (USO) with a male partner in the past 6 months were randomized. INTERVENTIONS: In SSB, five 90-minute groups used problem solving and skills rehearsal to increase HIV/STD risk awareness, condom use, and partner negotiation skills. In HE, one 60-minute group covered HIV/STD disease, testing, treatment, and prevention information. MAIN OUTCOME: Number of USOs at follow-up. RESULTS: A significant difference in mean USOs was obtained between SSB and HE over time (F = 67.2, P < 0.0001). At 3 months, significant decrements were observed in both conditions. At 6 months, SSB maintained the decrease and HE returned to baseline (P < 0.0377). Women in SSB had 29% fewer USOs than those in HE. CONCLUSIONS: Skills building interventions can produce ongoing sexual risk reduction in women in community drug treatment.

The impact of cumulative maternal trauma and diagnosis on parenting behavior.

This study examines the relative contributions of cumulative maternal trauma, substance use, depressive and posttraumatic stress diagnoses on parental abuse potential, punitiveness, and psychological and physical aggression in a sample of 176 urban mothers. Participants were categorized into four groups: substance use (n = 41), depressed (n = 40), comorbid (n = 47), and control (n = 48). Participants in the three diagnostic groups reported significantly greater interpersonal trauma exposure than did controls. Hierarchical regressions reveal that cumulative trauma is a significant predictor of all parenting outcomes, even after controlling for demographic and diagnostic variables. Substance use and depression are significantly related to abuse potential, and PTSD is significantly negatively related to physical discipline, with no other significant associations between diagnostic status and parenting outcomes. These findings add to an important growing literature examining the impact of cumulative trauma on parental functioning. Implications for future research and parenting interventions are discussed.

Treatment outcomes for women with substance abuse and PTSD who have experienced complex trauma.

OBJECTIVE: This study assessed the effect of cognitive-behavioral therapy on a range of problems associated with complex trauma in a sample of women with comorbid substance use disorders and posttraumatic stress disorder (PTSD). METHODS: A total of 107 women with current or subthreshold PTSD and a current substance use disorder from an urban, low-income area were recruited from both community and clinical populations. Participants were recruited between 1997 and 2000. A quasi-experimental design was used, and participants who received cognitive-behavioral therapy (N=75) were compared with those in a control group who received no active study treatment (N=32). All participants were given the same list of community treatment resources and told that they could pursue services while participating in the study if they wished. RESULTS: At the end of treatment (three months postbaseline), compared with participants in the control group, those in the active treatment group showed significant reductions in symptoms of PTSD and alcohol use disorders, with a trend toward reductions in symptoms of drug use disorders. No significant differences were found between the groups on depression, dissociation, and social and sexual functioning outcomes. CONCLUSIONS: These findings underscore the challenge and necessity of addressing the unique and wide-ranging needs of women with substance use disorder who have been exposed to early and multiple interpersonal traumas.

Promising treatments for women with comorbid PTSD and substance use disorders.

OBJECTIVE: The authors' goal was to compare the efficacy of a manualized cognitive behavior therapy that addresses both posttraumatic stress disorder (PTSD) and substance abuse (seeking safety) with a manualized cognitive behavior therapy that addresses only substance abuse (relapse prevention) and with standard community care for the treatment of comorbid posttraumatic stress disorder (PTSD) and substance use disorder. METHOD: One hundred seven women from an urban, low-income population who had comorbid PTSD and substance use disorder were randomly assigned to receive the two kinds of cognitive behavior therapy or received standard community treatment. Participants were recruited from both community and clinical populations and evaluated with structured clinical instruments. Forty-one women received seeking safety therapy, 34 received relapse prevention therapy, and 32 received standard community care. RESULTS: At the end of 3 months of treatment, participants in both cognitive behavior therapy conditions had significant reductions in substance use, PTSD, and psychiatric symptoms, but community care participants worsened over time. Both groups receiving cognitive behavior therapy sustained greater improvement in substance use and PTSD symptoms at 6-month and 9-month follow-ups than subjects in the community care group. CONCLUSIONS: Seeking safety and relapse prevention are efficacious short-term treatments for low-income urban women with PTSD, substance use disorder, and other psychiatric symptoms.

Skills training in affective and interpersonal regulation followed by exposure: a phase-based treatment for PTSD related to childhood abuse.

Fifty-eight women with posttraumatic stress disorder (PTSD) related to childhood abuse were randomly assigned to a 2-phase cognitive-behavioral treatment or a minimal attention wait list. Phase 1 of treatment included 8 weekly sessions of skills training in affect and interpersonal regulation; Phase 2 included 8 sessions of modified prolonged exposure. Compared with those on wait list, participants in active treatment showed significant improvement in affect regulation problems, interpersonal skills deficits, and PTSD symptoms. Gains were maintained at 3- and 9-month follow-up. Phase 1 therapeutic alliance and negative mood regulation skills predicted Phase 2 exposure success in reducing PTSD, suggesting the value of establishing a strong therapeutic relationship and emotion regulation skills before exposure work among chronic PTSD populations.

A randomized comparison of group cognitive-behavioral therapy and group interpersonal psychotherapy for the treatment of overweight individuals with binge-eating disorder.

BACKGROUND: Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED. METHODS: One hundred sixty-two overweight patients meeting DSM-IV criteria for BED were randomly assigned to 20 weekly sessions of either group CBT or group IPT. Assessments of binge eating and associated eating disorder psychopathology, general psychological functioning, and weight occurred before treatment, at posttreatment, and at 4-month intervals up to 12 months following treatment. RESULTS: Binge-eating recovery rates were equivalent for CBT and IPT at posttreatment (64 [79%] of 81 vs 59 [73%] of 81) and at 1-year follow-up (48 [59%] of 81 vs 50 [62%] of 81). Binge eating increased slightly through follow-up but remained significantly below pretreatment levels. Across treatments, patients had similar significant reductions in associated eating disorders and psychiatric symptoms and maintenance of gains through follow-up. Dietary restraint decreased more quickly in CBT but IPT had equivalent levels by later follow-ups. Patients' relative weight decreased significantly but only slightly, with the greatest reduction among patients sustaining recovery from binge eating from posttreatment to 1-year follow-up. CONCLUSIONS: Group IPT is a viable alternative to group CBT for the treatment of overweight patients with BED. Although lacking a nonspecific control condition limits conclusions about treatment specificity, both treatments showed initial and long-term efficacy for the core and related symptoms of BED.
