Long-term effectiveness of web-based cognitive behavioral therapy for patients with eating disorders.

PURPOSE: To evaluate the long-term effectiveness of a web-based therapist-delivered cognitive behavioral therapy (CBT) for patients with eating disorders (ED). METHODS: We used follow-up data from a randomized controlled trial that evaluated a web-based CBT on ED psychopathology and related health, compared to a waiting list control (WL) condition. As participants of the WL condition started the intervention after their waiting period, follow-up data included participants from both groups. The primary outcome was change from baseline, at 3, 6, and 12-month intervals in ED psychopathology, analyzed using mixed models for repeated measures. Secondary outcomes included body dissatisfaction, BMI, physical health, mental health, self-esteem, quality of life, and social functioning. RESULTS: The population comprised 212 participants in total, in three subgroups: bulimia nervosa (BN; n = 44), binge eating disorder (BED; n = 83), and ED not otherwise specified (EDNOS; n = 85). Treatment effects were sustained during follow-up, with generally large effect sizes for the reduction of ED psychopathology and body dissatisfaction, and small to moderate effect sizes for physical and mental health, self-esteem, social functioning, and quality of life. Most effects were found for all three subgroups, except for long-term improvements in self-esteem and quality of life among participants with BN and EDNOS. CONCLUSION: This study showed long-term sustainability of treatment effects up to 1-year post-treatment of a web-based therapist-delivered CBT for patients with various ED. LEVEL OF EVIDENCE: Level IV, evidence obtained from multiple time series analysis, with intervention.

A Systematic Review of Substance Use (Disorder) in Individuals with Mild to Borderline Intellectual Disability.

Although the attention for substance use (SU) and SU disorders (SUD) among individuals with mild to borderline intellectual disability (MBID) has been growing exponentially, this form of dual diagnosis has largely been ignored by addiction medicine. In this article, we systematically review the research between January 2000 and June 2018 on the prevalence, assessment, and treatment of SU(D) among children, adolescents, and adults with MBID. A total of 138 articles were included. It is concluded that individuals with MBID are likely to be at a higher risk for developing SUD compared to those without MBID. Future research should focus on the detection of MBID among patients being treated in addiction medicine, the development and implementation of systematic assessment methods of SU(D) among individuals with MBID, and the development and evaluation of prevention and treatment interventions. System integration, interdisciplinary collaboration, and the development of tailored treatment for individuals with MBID are advised to improve treatment access and outcome for those who have developed SUD.

Cognitive deficits in problematic drinkers with and without mild to borderline intellectual disability.

We examined cognitive deficits in problematic drinkers with and without mild to borderline intellectual disability (MBID). Problematic drinkers were expected to show a significantly lower estimated performance IQ (PIQ), but not a lower estimated verbal IQ (VIQ), compared to light drinkers. Participants ( N = 474) were divided into four groups based on IQ and severity of alcohol use-related problems. IQ was estimated using (a short form of) the Wechsler Adult Intelligence Scale third edition. Severity of alcohol use-related problems was assessed using the Alcohol Use Disorder Identification Test. Overall, there were no significant differences between light and problematic drinkers on estimated VIQ. Within the group without MBID, estimated PIQ was significantly lower. Estimated PIQ was not lower in problematic drinkers with MBID compared to light drinkers with MBID. The results are indicative of cognitive deficits in problematic drinkers without MBID. Screening for cognitive deficits with additional instruments is advised.

Web-Based Cognitive Behavioral Therapy for Female Patients With Eating Disorders: Randomized Controlled Trial.

BACKGROUND: Many patients with eating disorders do not receive help for their symptoms, even though these disorders have severe morbidity. The Internet may offer alternative low-threshold treatment interventions. OBJECTIVE: This study evaluated the effects of a Web-based cognitive behavioral therapy (CBT) intervention using intensive asynchronous therapeutic support to improve eating disorder psychopathology, and to reduce body dissatisfaction and related health problems among patients with eating disorders. METHODS: A two-arm open randomized controlled trial comparing a Web-based CBT intervention to a waiting list control condition (WL) was carried out among female patients with bulimia nervosa (BN), binge eating disorder (BED), and eating disorders not otherwise specified (EDNOS). The eating disorder diagnosis was in accordance with the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and was established based on participants' self-report. Participants were recruited from an open-access website, and the intervention consisted of a structured two-part program within a secure Web-based application. The aim of the first part was to analyze participant's eating attitudes and behaviors, while the second part focused on behavioral change. Participants had asynchronous contact with a personal therapist twice a week, solely via the Internet. Self-report measures of eating disorder psychopathology (primary outcome), body dissatisfaction, physical health, mental health, self-esteem, quality of life, and social functioning were completed at baseline and posttest. RESULTS: A total of 214 participants were randomized to either the Web-based CBT group (n=108) or to the WL group (n=106) stratified by type of eating disorder (BN: n=44; BED: n=85; EDNOS: n=85). Study attrition was low with 94% of the participants completing the posttest assignment. Overall, Web-based CBT showed a significant improvement over time for eating disorder psychopathology (F97=63.07, P<.001, d=.82) and all secondary outcome measures (effect sizes between d=.34 to d=.49), except for Body Mass Index. WL participants also improved on most outcomes; however, effects were smaller in this group with significant between-group effects for eating disorder psychopathology (F201=9.42, P=.002, d=.44), body dissatisfaction (F201=13.16, P<.001, d=.42), physical health (F200=12.55, P<.001, d=.28), mental health (F203=4.88, P=.028, d=.24), self-esteem (F202=5.06, P=.026, d=.20), and social functioning (F205=7.93, P=.005, d=.29). Analyses for the individual subgroups BN, BED, and EDNOS showed that eating disorder psychopathology improved significantly over time among Web-based CBT participants in all three subgroups; however, the between-group effect was significant only for participants with BED (F78=4.25, P=.043, d=.61). CONCLUSIONS: Web-based CBT proved to be effective in improving eating disorder psychopathology and related health among female patients with eating disorders.

Not Two Sides of the Same Coin: A Qualitative Comparative Analysis of Post-Treatment Abstinence and Relapse.

Purpose: Substance use disorder (SUD) can be a chronic relapsing condition with poor treatment outcomes. Studies exploring factors associated with abstinence or relapse after treatment are often quantitative in nature, applying linear statistical approaches, while abstinence and relapse result from non-linear, complex, dynamic and synergistic processes. This study aims to explore these underlying dynamics using qualitative comparative analysis (QCA) as a mixed methods approach to further our understanding of factors contributing to post-treatment abstinence and relapse. Patients and Methods: In a prospective study, we gathered both qualitative and quantitative data pertaining to post-treatment substance use and the factors linked to substance use outcomes. These factors encompassed psychiatric comorbidity, intellectual disability, social disintegration, post-treatment support, and engagement in activities among patients who had undergone inpatient treatment for severe SUD (n = 58). QCA, a set-theoretic approach that considers the complex interplay of multiple conditions, was applied to discern which factors were necessary or sufficient for the occurrence of either abstinence or relapse. Results: We found two solutions predicting abstinence, and five for relapse. Post-treatment conditions (support and engagement in activities) were important for retaining abstinence. For relapse, individual baseline characteristics (intellectual disability, social disintegration, psychiatric comorbidity) combined with (post-)treatment factors (post-treatment support, activities) were important. Conclusion: Although abstinence and relapse represent opposing outcomes, they each exhibit distinct dynamics. To gain a comprehensive understanding of these dynamics, it is advisable to examine them as separate outcomes. For clinical practice, it can be worthwhile to recognize that fostering the conditions conducive to abstinence may differ from preventing the factors that trigger relapse.

This study explores why some people who struggle with addiction stay clean after treatment, while others relapse. Previous studies often used traditional statistical methods, with inconclusive results due to their inability to capture the complexity of this process. To address this, we used a different approach called qualitative comparative analysis (QCA). We collected information from 58 individuals who received inpatient treatment for their addiction. We looked at different factors like mental health problems, intellectual disability, the support they got from professionals and their social network, and whether they kept themselves busy with activities. We investigated how these factors are related to staying clean or relapse. With the help of QCA, we analyzed how these factors work together to cause either drug-free living or relapse. We found that staying clean was strongly linked to getting support after treatment and being involved in activities like hobbies or work. On the other hand, relapse was more likely in people with personal problems, like intellectual disabilities and mental health problems, when support and activities were lacking after treatment. In summary, our study indicates that staying clean and relapse are different processes with different factors at play. Helping someone stay clean may therefore require different strategies than preventing relapse. This insight can guide development of more personalized healthcare for individuals dealing with addiction.

Development of an Alcohol Refusal Training in Immersive Virtual Reality for Patients With Mild to Borderline Intellectual Disability and Alcohol Use Disorder: Cocreation With Experts in Addiction Care.

BACKGROUND: People with mild to borderline intellectual disability (MBID; IQ=50-85) are at risk for developing an alcohol use disorder (AUD). One factor contributing to this risk is sensitivity to peer pressure. Hence, tailored trainings are needed to practice alcohol refusal in impacted patients. Immersive virtual reality (IVR) appears promising to engage patients in dialogs with virtual humans, allowing to practice alcohol refusal realistically. However, requirements for such an IVR have not been studied for MBID/AUD. OBJECTIVE: This study aims to develop an IVR alcohol refusal training for patients with MBID and AUD. In this work, we cocreated our peer pressure simulation with experienced experts in addiction care. METHODS: We followed the Persuasive System Design (PSD) model to develop our IVR alcohol refusal training. With 5 experts from a Dutch addiction clinic for patients with MBID, we held 3 focus groups to design the virtual environment, persuasive virtual human(s), and persuasive dialog. Subsequently, we developed our initial IVR prototype and conducted another focus group to evaluate IVR and procedures for clinical usage, resulting in our final peer pressure simulation. RESULTS: Our experts described visiting a friend at home with multiple friends as the most relevant peer pressure situation in the clinical setting. Based on the identified requirements, we developed a social-housing apartment with multiple virtual friends present. Moreover, we embedded a virtual man with generic appearance to exert peer pressure using a persuasive dialog. Patients can respond to persuasive attempts by selecting (refusal) responses with varying degrees of risk for relapse in alcohol use. Our evaluation showed that experts value a realistic and interactable IVR. However, experts identified lacking persuasive design elements, such as paralanguage, for our virtual human. For clinical usage, a user-centered customization is needed to prevent adverse effects. Further, interventions should be therapist delivered to avoid try-and-error in patients with MBID. Lastly, we identified factors for immersion, as well as facilitators and barriers for IVR accessibility. CONCLUSIONS: Our work establishes an initial PSD for IVR for alcohol refusal trainings in patients with MBID and AUD. With this, scholars can create comparable simulations by performing an analogous cocreation, replicate findings, and identify active PSD elements. For peer pressure, conveying emotional information in a virtual human's voice (eg, paralanguage) seems vital. However, previous rapport building may be needed to ensure that virtual humans are perceived as cognitively capable entities. Future work should validate our PSD with patients and start developing IVR treatment protocols using interdisciplinary teams.

Using the Recovery Capital Model to Explore Barriers to and Facilitators of Recovery in Individuals with Substance Use Disorder, Psychiatric Comorbidity and Mild-to-Borderline Intellectual Disability: A Case Series.

Recovery capital (RC) encompasses the wide range of resources individuals can employ to recover from Substance Use Disorder (SUD). It consists of five subdomains: human, social, cultural, financial, and community RC. Negative recovery capital (NRC) represents the obstacles to recovery. Research on (N)RC in complex multimorbid populations is scarce. This study offers an initial exploration of the viability of (N)RC in three individuals with SUD, psychiatric comorbidities, and an intellectual disability (a triple diagnosis) in inpatient addiction treatment. We collected case file data, ranked recovery goals, and conducted follow-up interviews. The data were subjected to template analysis, using (N)RC domains as codes. All domains were prevalent and relevant, showing dynamic and reciprocal effects, influenced by critical life events acting as catalysts. Notably, during treatment, patients prioritized individual skill development despite challenges in other domains. RC emerges as a valuable concept for mapping recovery barriers and facilitators in individuals with a triple diagnosis, serving as an alternative to the medical model and complementing the biopsychosocial model. It provides a systematic framework to assess critical factors for recovery in complex cases and accordingly align interventions. Future studies should explore the intersections of NRC domains and the dynamic nature of (N)RC to enhance the understanding of the challenges faced by individuals with a triple diagnosis.

Immersive Virtual Reality Avatars for Embodiment Illusions in People With Mild to Borderline Intellectual Disability: User-Centered Development and Feasibility Study.

BACKGROUND: Immersive virtual reality (IVR) has been investigated as a tool for treating psychiatric conditions. In particular, the practical nature of IVR, by offering a doing instead of talking approach, could support people who do not benefit from existing treatments. Hence, people with mild to borderline intellectual disability (MBID; IQ=50-85) might profit particularly from IVR therapies, for instance, to circumvent issues in understanding relevant concepts and interrelations. In this context, immersing the user into a virtual body (ie, avatar) appears promising for enhancing learning (eg, by changing perspectives) and usability (eg, natural interactions). However, design requirements, immersion procedures, and proof of concept of such embodiment illusion (ie, substituting the real body with a virtual one) have not been explored in this group. OBJECTIVE: Our study aimed to establish design guidelines for IVR embodiment illusions in people with MBID. We explored 3 factors to induce the illusion, by testing the avatar's appearance, locomotion using IVR controllers, and virtual object manipulation. Furthermore, we report on the feasibility to induce the embodiment illusion and provide procedural guidance. METHODS: We conducted a user-centered study with 29 end users in care facilities, to investigate the avatar's appearance, controller-based locomotion (ie, teleport, joystick, or hybrid), and object manipulation. Overall, 3 iterations were conducted using semistructured interviews to explore design factors to induce embodiment illusions in our group. To further understand the influence of interactions on the illusion, we measured the sense of embodiment (SoE) during 5 interaction tasks. RESULTS: IVR embodiment illusions can be induced in adults with MBID. To induce the illusion, having a high degree of control over the body outweighed avatar customization, despite the participants' desire to replicate their own body image. Similarly, the highest SoE was measured during object manipulation tasks, which required a combination of (virtual) locomotion and object manipulation behavior. Notably, interactions that are implausible (eg, teleport and occlusions when grabbing) showed a negative influence on SoE. In contrast, implementing artificial interaction aids into the IVR avatar's hands (ie, for user interfaces) did not diminish the illusion, presuming that the control was unimpaired. Nonetheless, embodiment illusions showed a tedious and complex need for (control) habituation (eg, motion sickness), possibly hindering uptake in practice. CONCLUSIONS: Balancing the embodiment immersion by focusing on interaction habituation (eg, controller-based locomotion) and lowering customization effort seems crucial to achieve both high SoE and usability for people with MBID. Hence, future studies should investigate the requirements for natural IVR avatar interactions by using multisensory integrations for the virtual body (eg, animations, physics-based collision, and touch) and other interaction techniques (eg, hand tracking and redirected walking). In addition, procedures and use for learning should be explored for tailored mental health therapies in people with MBID.

Substance use disorders in people with intellectual disability.

PURPOSE OF REVIEW: To provide an overview of studies on substance use and substance use disorder (SUD) in individuals with mild intellectual disability or borderline intellectual functioning (MID-BIF). RECENT FINDINGS: Many individuals with MID-BIF use tobacco, alcohol, and drugs. On average, rates of substance use and SUD are similar to or even higher than those in peers with average intelligence. Individuals with MID-BIF are overrepresented in (forensic) addiction care. Several instruments are now available for the assessment of SUD and its risk factors in this target group. Prevention and intervention programs have been shown feasible and with promising outcomes, although the evidence base is still small. Professionals in addiction care and intellectual disability care facilities show deficiencies in skills in addressing SUD in clients with MID-BIF. SUMMARY: Research in this area is still in its infancy, though an increasing number of studies show promising outcomes regarding case identification, assessment, and treatment of SUD in intellectual disability. Policy and practice should be adapted to the characteristics of individuals with MID-BIF.

Prevalence of cognitive impairment in patients with substance use disorder.

INTRODUCTION AND AIMS: Cognitive impairments in substance use disorder predict treatment outcome and are assumed to differ between substances. They often go undetected, thus the current study focuses on the prevalence of and differences in cognitive functioning across substances by means of a cognitive screen at the early stage of addiction treatment. DESIGN AND METHODS: The Montreal Cognitive Assessment was administered to outpatients seeking treatment for substance use disorder. Patient characteristics (age, years of regular use, polysubstance use, severity of dependence/abuse, depression, anxiety and stress) were also taken into account. RESULTS: A total of 656 patients were included (n = 391 used alcohol, n = 123 used cannabis, n = 100 used stimulants and n = 26 used opioids). The prevalence of cognitive impairments was 31%. Patients using alcohol had a lower total- and memory domain score than those using cannabis. Patients using opioids scored lower on visuospatial abilities than those using cannabis or stimulants. Younger patients scored higher than older patients. No effect was found for the other investigated characteristics. DISCUSSION AND CONCLUSIONS: Given the high prevalence of cognitive impairments, standard screening at an early stage of treatment is important to determine the course of treatment and maximise treatment outcome. Caution is needed in interpreting results about opioids due to an underrepresentation of this patient group, and more research is needed on the effect of age on Montreal Cognitive Assessment performance.

The efficacy of an e-learning prevention program for substance use among adolescents with intellectual disabilities: A pilot study.

BACKGROUND AND AIMS: Adolescents with Intellectual Disability (ID) are at risk for tobacco and alcohol use, yet little or no prevention programs are available for this group. 'Prepared on time' is an e-learning program based on the attitude - social influence - efficacy model originally developed for fifth and sixth grades of mainstream primary schools. The goals of this study were (1) to examine the lifetime use of tobacco and alcohol among this target group and (2) to gain a first impression of the efficacy of 'Prepared on time' among 12-16-year old students with moderate or mild ID (MMID). METHODS AND PROCEDURES: Students form three secondary special-needs schools were assigned to the experimental (e-learning) group (n=37) or the control group (n=36). Pre-intervention and follow-up data (3 weeks after completion) were gathered using semi-structured interviews inquiring about substance use among students with MMID and the behavioral determinants of attitude, subjective norm, modelling, intention, and knowledge. RESULTS: The lifetime tobacco use and alcohol consumption rates in our sample were 25% and 59%, respectively. The e-learning program had a positive effect on the influence of modelling of classmates and friends. No significant effects were found on other behavioral determinants and knowledge. CONCLUSIONS AND IMPLICATIONS: A substantial proportion of adolescents with MMID in secondary special-needs schools use tobacco or alcohol. This study showed that an e-learning prevention program can be feasible for adolescents with MMID.
