Psychological treatments for concurrent posttraumatic stress disorder and substance use disorder: a systematic review.

Debora van Dam; Ellen Vedel; Thomas Ehring; Paul M. G. Emmelkamp

This article gives an overview of research into psychological treatments for concurrent posttraumatic stress disorder (PTSD) and substance used disorder (SUD), with a special focus on the effectiveness of treatments addressing both disorders compared to treatments addressing one of the disorders alone. In addition, a distinction is made between trauma-focused versus non-trauma-focused therapies for concurrent PTSD and SUD. The databases Embase, Psychinfo, Medline and Web of science were searched for relevant articles. In total, seventeen studies were identified evaluating ten treatments protocols (six trauma-focused and four non-trauma-focused treatment approaches). In general, the studies showed pre-post reductions for PTSD and/or SUD symptoms. Although most treatments for concurrent PTSD and SUD did not prove to be superior to regular SUD treatments, there are some promising preliminary results suggesting that some patients might benefit from trauma-focused interventions. However, the lack of methodologically sound treatment trials makes it difficult to draw firm conclusions. Methodological limitations are discussed, along with recommendations for future research.

This study aimed to cross-validate and extend earlier findings regarding the diagnostic efficiency of the four-item Primary Care Posttraumatic Stress Disorder Screen (PC-PTSD) as a screening questionnaire for posttraumatic stress disorder (PTSD) among civilian patients with substance use disorder (SUD). The PC-PTSD was originally developed in a Veteran Affairs primary care setting (Prins, Ouimette, Kimerling, Cameron, Hugelshofer, Shaw-Hegwer, et al., 2004) and has been widely used in the U.S. army. The diagnostic efficiency of the screener was compared to those of an extended eight-item version of the PC-PTSD and the Posttraumatic Diagnostic Scale (PDS). The sample consisted of 142 participants with SUD and most of the participants (89%) were still using substances in the month preceding the assessment. Results showed a high sensitivity (.86) and moderate specificity (.57) for the PC-PTSD when using a cutoff score of 2. The diagnostic efficiency of the PC-PTSD was equivalent to the extended eight-item version and the 17-item PDS. Results suggest that the original PC-PTSD is a useful screening instrument for PTSD within a civilian SUD population. These findings have important clinical implications because screening for PTSD among patients with SUD is crucial to ascertain appropriate treatment allocation.

Trauma-focused treatment for posttraumatic stress disorder combined with CBT for severe substance use disorder: a randomized controlled trial

Debora van Dam; Thomas Ehring; Ellen Vedel; Paul M. G. Emmelkamp

BackgroundThis randomized controlled trial (RCT) investigated the effectiveness of a combined treatment for co-morbid Posttraumatic Stress Disorder (PTSD) and severe Substance Use Disorder (SUD).MethodsStructured Writing Therapy for PTSD (SWT), an evidence-based traumafocused intervention, was added on to Treatment As Usual (TAU), consisting of an intensive cognitive behavioral inpatient or day group treatment for SUD. The outcomes of the combined treatment (TAU + SWT) were compared to TAU alone in a sample of 34 patients.ResultsResults showed a general reduction of SUD symptoms for both TAU + SWT and TAU. Treatment superiority of TAU + SWT was neither confirmed by interaction effects (time x condition) for SUD or PTSD symptoms, nor by a group difference for SUD diagnostic status at post-treatment. However, planned contrasts revealed that improvements for PTSD severity over time were only significant within the TAU + SWT group. In addition, within the TAU + SWT group the remission of PTSD diagnoses after treatment was significant, which was not the case for TAU. Finally, at post-treatment a trend was noticed for between group differences for the number of PTSD diagnoses favoring TAU + SWT above TAU.ConclusionsIn sum, the current study provides preliminary evidence that adding a trauma-focused treatment on to standard SUD treatment may be beneficial.

Fleur L. Kraanen; Ellen Vedel; Agnes Scholing; Paul M. G. Emmelkamp

The present study investigated whether (combinations of) specific substance use disorders predicted any and severe perpetration and victimization in males and females entering substance abuse treatment. All patients (N = 1799) were screened for IPV perpetration and victimization; almost one third of the sample committed or experienced any IPV in the past year. For males, an alcohol use disorder in combination with a cannabis and/or cocaine use disorder significantly predicted any IPV (perpetration and/or victimization) as well as severe IPV perpetration. For females, alcohol and cocaine abuse/dependence predicted both any IPV (perpetration and/or victimization) and severe IPV perpetration. Results from the present study emphasize the importance of routinely assessing IPV in patients in substance abuse treatment and demonstrate that clinicians should be particularly alert for IPV in patients with specific substance use disorder combinations.

BackgroundAttention deficit hyperactivity disorder (ADHD) frequently co-occurs with substance use disorders (SUD). The combination of ADHD and SUD is associated with a negative prognosis of both SUD and ADHD. Pharmacological treatments of comorbid ADHD in adult patients with SUD have not been very successful. Recent studies show positive effects of cognitive behavioral therapy (CBT) in ADHD patients without SUD, but CBT has not been studied in ADHD patients with comorbid SUD.Methods/designThis paper presents the protocol of a randomized controlled trial to test the efficacy of an integrated CBT protocol aimed at reducing SUD as well as ADHD symptoms in SUD patients with a comorbid diagnosis of ADHD. The experimental group receives 15 CBT sessions directed at symptom reduction of SUD as well as ADHD. The control group receives treatment as usual, i.e. 10 CBT sessions directed at symptom reduction of SUD only. The primary outcome is the level of self-reported ADHD symptoms. Secondary outcomes include measures of substance use, depression and anxiety, quality of life, health care consumption and neuropsychological functions.DiscussionThis is the first randomized controlled trial to test the efficacy of an integrated CBT protocol for adult SUD patients with a comorbid diagnosis of ADHD. The rationale for the trial, the design, and the strengths and limitations of the study are discussed.Trial registrationThis trial is registered in http://www.clinicaltrials.gov as NCT01431235.

Individual cognitive-behavioral therapy and behavioral couples therapy in alcohol use disorder: a comparative evaluation in community-based addiction treatment centers.

Ellen Vedel; Paul M. G. Emmelkamp; Gerard M. Schippers

Background: Alcohol abuse serves as a chronic stressor between partners and has a deleterious effect on relationship functioning. Behavioral Couples Therapy (BCT) for alcohol dependence, studied as an adjunct to individual outpatient counseling, has shown to be effective in decreasing alcohol consumption and enhancing marital functioning, but no study has directly tested the comparative effectiveness of stand-alone BCT versus an individually focused cognitive-behavioral therapy (CBT) in a clinical community sample. Methods: The present study is a randomized clinical trial evaluating the effectiveness of stand-alone BCT (n = 30) compared to individual CBT (n = 34) in the treatment of alcohol use disorders in community treatment centers in Dutch male and female alcoholics and their partners. Results: Results show both BCT and CBT to be effective in changing drinking behavior after treatment. BCT was not found to be superior to CBT. Marital satisfaction of the spouse increased significantly in the BCT condition but not in the CBT condition, the differences being significant at the post-test. Patients’ self-efficacy to withstand alcohol-related high-risk situations increased significantly in both treatment conditions, but more so in CBT than in BCT after treatment. Treatment involvement of the spouse did not increase retention. Conclusion: Regular practitioners in community treatment centers can effectively deliver both treatments. Stand-alone BCT is as effective as CBT in terms of reduced drinking and to some extent more effective in terms of enhancing relationship satisfaction. However, BCT is a more costly intervention, given that treatment sessions lasted almost twice as long as individual CBT sessions.

Screening on Perpetration and Victimization of Intimate Partner Violence (IPV): Two Studies on the Validity of an IPV Screening Instrument in Patients in Substance Abuse Treatment

Fleur L. Kraanen; Ellen Vedel; Agnes Scholing; Paul M. G. Emmelkamp

Background About 50% of patients in substance abuse treatment with a partner perpetrated and/or experienced intimate partner violence in the past year. To date, there are no screeners to identify both perpetrators and victims of partner intimate violence in a substance abusing population. We developed a 4 item screening instrument for this purpose, the Jellinek Inventory for assessing Partner Violence (J-IPV). Important strengths of the J-IPV are that it takes only 2 minutes to administer and is easy to use and to score. Methods To investigate the validity of the J-IPV, two independent studies were conducted including 98 and 99 participants, respectively. Aim of the second study was to cross-validate findings from the first study. Psychometric properties of the J-IPV were determined by calculating sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ratio’s by comparing J-IPV outcomes to outcomes on the Revised Conflict Tactics Scales (‘gold standard’). Also, receiver operator characteristics (ROC)-curves were determined to weight sensitivity and specificity as a result of different J-IPV cutoffs, and the area under the curve (AUC) was calculated. Results Results of the first study demonstrated that the J-IPV possesses good psychometric properties to detect perpetrators and victims of any as well as severe intimate partner violence. Results from the second study replicated findings from the first study. Conclusions We recommend administering the J-IPV to patients entering substance abuse treatment. If perpetrators and victims of partner violence are identified, action can be taken to stop IPV perpetration and arrange help for victims, for example by offering perpetrators treatment or by providing safety planning or advocacy interventions to victims.

Screening for posttraumatic stress disorder in civilian substance use disorder patients: Cross-validation of the Jellinek-PTSD screening questionnaire

Debora van Dam; Thomas Ehring; Ellen Vedel; Paul M. G. Emmelkamp

This study aimed to cross-validate earlier findings regarding the diagnostic efficiency of a modified version of the Primary Care Posttraumatic Stress Disorder (PC-PTSD) screening questionnaire (A. Prins, P. Ouimette, R. Kimerling, R. P. Cameron, D. S. Hugelshofer, J. Shaw-Hegwer, et al., 2004). The PC-PTSD is a four-item screening questionnaire for Posttraumatic Stress Disorder (PTSD). Based on former research, we adapted the PC-PTSD for use among civilian substance use disorder (SUD) patients (D. Van Dam, T. Ehring, E. Vedel, & P. M. G. Emmelkamp, 2010). This version will be referred to as the Jellinek-PTSD (J-PTSD) screening questionnaire. Results showed a high sensitivity (.87), specificity (.75), and overall efficiency (.77) of the J-PTSD in detecting PTSD when using a cutoff score of 2. This confirms findings in former research, and suggests that the J-PTSD is a useful screening instrument for PTSD within a civilian SUD population. Both PTSD and SUD are severe and disabling disorders causing great psychological distress. An early recognition of PTSD among SUD patients makes it possible to address PTSD symptoms in time, which may ultimately lead to an improvement of symptoms in this complex patient group.

Behavioral couple therapy in the treatment of a female alcohol dependent patient with comorbid depression, anxiety and personality disorders

Ellen Vedel; Paul M. G. Emmelkamp

Behavioral Couple Therapy (BCT) has shown to be effective in the treatment of alcohol dependence. However, it is still unclear whether this intervention is effective in severe caseswith comorbid other conditions. The aim of the present study is to illustrate the assessment, case conceptualization, prioritizing of interventions and treatment in a female “treatment resistant” alcohol-dependent patient, with comorbid depression, anxiety, personality disorders, andmarital problems, using a BCT manual. In total, the treatment consisted of 19 sessions, during a 7-month period. Results show BCT to be successful in treating alcohol dependence and to some extent increasing marital satisfaction. At posttreatment the patient did no longer meet criteria for major depressive disorder. At 3-month follow-up she had been abstinent for 51/2 months, with a 2-day lapse, and her depressive disorder was still in full remission. This case demonstrates—even with severe comorbid conditions—that targeting the drinking problem is the treatment of choice. However, we stress the importance of a thorough assessment of other Axis I and II disorders.
