The impact of chronic pain and depression on medication for opioid use disorder treatment: A mixed-methods analysis.

Background: Opioid use disorder (OUD) is associated with significant morbidity and mortality. Medication for opioid use disorder (MOUD) is a cost-effective treatment, but retention rates vary widely. Aim: Mixed methods studies are needed to better understand how depression and pain impact the experience of OUD and MOUD treatment experiences. Methods: Participants were recruited from an urban addiction treatment center in the United States. Along with demographic characteristics, current pain severity, pain interference, pain catastrophizing, and depression were assessed via self-report. Correlational analyses, multivariable logistic regression models, Fisher exact tests, and Wilcoxon signed rank tests were used to examine the impact of demographic characteristics, physical pain, and depression on multiple treatment outcomes: 90-day treatment engagement (total number of dispensed MOUD doses), retention (yes/no still in treatment at 90 days), and opioid use (positive/negative urinalysis for opioids at 90 days). Ten participants were interviewed about their history with physical pain, depression, opioid use, and OUD treatment experiences. Themes were identified using a rapid analysis, top-down approach. Results: Fifty participants enrolled in the study and received buprenorphine (12%) or methadone (88%). Older age was associated with 90-day treatment engagement. Higher depression scores were associated with a positive opioid urinalysis at 90-day follow-up. In interviews, participants reported experiencing chronic physical pain and depression before and during their OUD and an interest in addressing mental and physical health in addiction treatment. Conclusions: Addressing co-occurring physical and mental health concerns during MOUD treatment has the potential to improve the treatment experience and abstinence from opioids.

The impact of State of Surrender on the relationship between engagement in substance use treatment and meaning in life presence: a pilot study.

The current study examined the construct of State of Surrender (SoS)-defined as a willingness to accept, without resistance, what is to come-and investigated SoS as a statistical mediator of the relationship between engagement in substance use treatment and meaning in life (MIL). Using a cross-sectional design, participants were 123 people involved with the legal system participating in a 6-month residential treatment program for substance use. Results showed that measures of treatment engagement, including treatment participation, counselor rapport, and peer support, were all positively associated with SoS scores (R 2s ≥ 21.16). Moreover, while controlling for time spent in treatment, SoS statistically mediated the positive association between aspects of treatment engagement and MIL. State of Surrender may be a targetable process in substance use treatment that aids in recovery by orienting clients toward what they find meaningful in life. Future directions and practical considerations are discussed.

Understanding autism and its treatment: The child's perspective.

INTRODUCTION: While parents' and professionals' perceptions regarding children with autism spectrum disorder (ASD) have been studied extensively, limited data regarding the perspectives of children with ASD on their needs and the challenges they face are available. The study aimed to examine how children with ASD understand their condition and the aims of the interventions they undergo. METHODS: Nineteen children and adolescents (ages 5.7-14.2 years) formally diagnosed with ASD, with borderline to high intelligence (range 70-140), and able to converse verbally were interviewed in person at a child development clinic. A qualitative approach was used to capture children's perceptions of their strengths and challenges and their understanding of a novel ASD treatment. The interview included direct and projective open-ended questions on each topic. Interpretive content analysis was used to evaluate the children's answers. Medical data were extracted from medical records. The children's parents completed questionnaires on their children's disability levels, awareness of ASD diagnosis, and sociodemographic details. FINDINGS: Children spoke of their embodied sensations and feelings and discussed "normality" vs. "disability." They varied in their awareness of their diagnosis/symptoms, and only one boy named his diagnosis and described its consequences in detail. Most children lacked an understanding of the educational and therapeutic aspects of the goals set for them. DISCUSSION AND CONCLUSIONS: Children with ASD are aware of their unique emotional and behavioral challenges. Nevertheless, they are frequently excluded from the process of patient information provision and lack an understanding of the goals of interventions. Findings suggest the need to explore developmentally and emotionally adaptive ways to involve children with ASD in discussions of their condition and possible interventions.

Exploring predictors of substance use disorder treatment engagement with machine learning: The impact of social determinants of health in the therapeutic landscape.

BACKGROUND: Improved knowledge of factors that influence treatment engagement could help treatment providers and systems better engage patients. The present study used machine learning to explore associations between individual- and neighborhood-level factors, and SUD treatment engagement. METHODS: This was a secondary analysis of the Global Appraisal of Individual Needs (GAIN) dataset and United States Census Bureau data utilizing random forest machine learning and generalized linear mixed modelling. Our sample (N = 15,873) included all people entering SUD treatment at GAIN sites from 2006 to 2012. Predictors included an array of demographic, psychosocial, treatment-specific, and clinical measures, as well as environment-level measures for the neighborhood in which patients received treatment. RESULTS: Greater odds of treatment engagement were predicted by adolescent age and psychiatric comorbidity, and at the neighborhood-level, by low unemployment and high population density. Lower odds of treatment engagement were predicted by Black/African American race, and at the neighborhood-level by high rate of public assistance and high income inequality. Regardless of the degree of treatment engagement, individuals receiving treatment in areas with high unemployment, alcohol sale outlet concentration, and poverty had greater substance use and related problems at baseline. Although these differences reduced with treatment and over time, disparities remained. CONCLUSIONS: Neighborhood-level factors appear to play an important role in SUD treatment engagement. Regardless of whether individuals engage with treatment, greater loading on social determinants of health such as unemployment, alcohol sale outlet density, and poverty in the therapeutic landscape are associated with worse SUD treatment outcomes.

Referral pathways to early intervention services for psychosis and their influence on perceptions of care: An interpretive phenomenological analysis.

AIM: Most young adults experiencing psychosis enter early intervention services (EIS) via inpatient and emergency departments. These experiences are suggested to negatively impact their views of treatment and engagement in EIS. However, limited research has examined the impact of young adults' prior help-seeking experiences on these outcomes. The present study aimed to explore how young adults engaged in EIS have experienced initial help-seeking and make sense of these experiences in the context of their current treatment. METHODS: Using an interpretative phenomenological analysis approach, semi-structured interviews were conducted with 12 young adults (mean age = 24.83) within their first 3-12 months of treatment in EIS. Interviews aimed to examine their experiences of help-seeking and referral to EIS as well as the impact of these experiences on their subsequent perception of, and engagement with EIS. RESULTS: 3 superordinate themes emerged: (1) Navigating the Maze of Healthcare (2) Dignity and (3) Impact of Help-Seeking and Referral Experiences. Participants with referral pathways involving urgent care services described more adversity during their referral pathway and tended to describe help-seeking experiences as contributing to negative views towards EIS and diminished engagement in treatment. CONCLUSIONS: The impact of early negative experiences with healthcare on views towards EIS and engagement is evident in participants' accounts. Sense making was further contextualized by participants' illness insight, degree of recovery, and social support throughout experiences. Emergent themes highlight the need for psychiatric services to emphasize service users' dignity and for EIS to provide opportunities for patients to process past negative mental healthcare experiences to strengthen engagement.

Cognitive Behavioral Therapy: Strategies for Enhancing Treatment Engagement.

Treatment engagement, crucial in cognitive behavioral therapy (CBT) outcomes, centers on consistent implementation of between-session homework. This article explores clinical features affecting engagement, including challenges related to psychosocial stressors and negative core beliefs. Empirical evidence supports the positive causal and correlational relationship between homework and symptom reduction. Recent studies highlight the role of patient beliefs and suggest a collaborative approach in homework design. The CBT account of treatment engagement emphasizes clinician behavior, patient beliefs, and task specificity. The comprehensive model of homework in CBT involves careful planning, collaborative review, and addressing patient-specific challenges, providing valuable clinical insights.

Difficult-to-Engage Patients with Severe Mental Illness in Rural Community Settings: Results of the Greek Hybrid Assertive Community Treatment Model of Mental Healthcare.

Background: Modified Assertive Community Treatment (ACT) in rural settings may be effective in the care of patients with severe mental illness (SMI) that are difficult to engage in community care. The objective of the present study was to explore the impact of the care by a hybrid ACT team on SMI patients' hospitalizations, length of hospital stay, symptomatology and functioning in a rural community treatment setting in Greece. Methods: The hybrid ACT team is an expansion of the services of the well-established generic Mobile Mental Health Unit in a rural area of Northwest Greece, and delivers home-based care for patients with SMI. This was a 3-year prospective, mirror image, pre-post observational study. Patients' symptomatology, functioning and general outcome were measured with the use of the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Functioning Scale (GAF), and the Health of the Nation Outcome Scale (HοNOS). Results: The mean age of the 23 enrolled patients was 52.4 years and the mean age of disease onset was 23.5 years, with a mean number of hospitalizations 10.74. Over the 16-month follow-up patients' hospitalizations, both voluntary and involuntary, had been significantly reduced by almost 80%. Length of hospital stay had been significantly reduced by 87%, whereas patients' functioning and symptomatology had been significantly improved, by 17% and 14.5%, respectively. Conclusions: The model of hybrid ACT in rural areas in Greece may be effective in the treatment of difficult-to-engage patients with SMI and may improve patients' outcomes.

Perspectives of Community Nurses on Treatment Engagement of Persons with Severe Mental Illnesses (PwSMI): A Qualitative Study from South India.

Background: There is increasing evidence of the need for treatment engagement between Persons with Severe Mental Illnesses (PwSMIs) and Mental Health Professionals (MHPs). This therapeutic process involves collaborative work between patients and MHPs, which improves the condition. Community nurses are uniquely positioned to facilitate this process as they act as the focal point of interaction between patients and the health system. Methods: This qualitative study explored the community nurses' experiences in treatment engagement with PwSMI through eight group interviews of 35 community nurses from District Mental Health Programs (DMHPs) across Karnataka (South India) from February 2020 to March 2020. The audio recordings of the interviews were transcribed and coded to arrive at themes and subthemes. Results: The major themes identified were factors influencing treatment engagement, strategies to tackle treatment nonengagement, and challenges in dealing with nonengagement. The reasons for nonengagement were lack of insight and lack of knowledge of sociocultural, logistic, and treatment-related factors. The DMHP teams contacted patients through phone calls, home visits, and liaisons with health workers and intervened with them through education and depot injections. The major challenges were difficulty conducting home visits, distances, the unavailability of medications, and the need for adequate infrastructure and human resources. Conclusion: Community nurses address a few factors of nonengagement, such as insight, sociocultural factors, and treatment-related factors. Addressing the systemic challenges and adequate training of nurses in intervening in the dropped-out PwSMIs would help to reduce the treatment gap.

Barriers and facilitators to mental health treatment access and engagement for LGBTQA+ people with psychosis: a scoping review protocol.

BACKGROUND: The prevalence of psychosis has been shown to be disproportionately high amongst sexual and gender minority individuals. However, there is currently little consideration of the unique needs of this population in mental health treatment, with LGBTQA+ individuals facing barriers in accessing timely and non-stigmatising support for psychotic experiences. This issue deserves attention as delays to help-seeking and poor engagement with treatment predict worsened clinical and functional outcomes for people with psychosis. The present protocol describes the methodology for a scoping review which will aim to identify barriers and facilitators faced by LGBTQA+ individuals across the psychosis spectrum in help-seeking and accessing mental health support. METHODS: A comprehensive search strategy will be used to search Medline, PsycINFO, Embase, Scopus, LGBTQ+ Source, and grey literature. Original studies of any design, setting, and publication date will be included if they discuss barriers and facilitators to mental health treatment access and engagement for LGBTQA+ people with experiences of psychosis. Two reviewers will independently screen titles/abstracts and full-text articles for inclusion in the review. Both reviewers will then extract the relevant data according to pre-determined criteria, and study quality will be assessed using the Joanna Briggs Institute (JBI) critical appraisal checklists. Key data from included studies will be synthesised in narrative form according to the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews. DISCUSSION: The results of this review will provide a comprehensive account of the current and historical barriers and facilitators to mental healthcare faced by LGBTQA+ people with psychotic symptoms and experiences. It is anticipated that the findings from this review will be relevant to clinical and community services and inform future research. Findings will be disseminated through publication in a peer-reviewed journal and presented at conferences. SCOPING REVIEW REGISTRATION: This protocol is registered in Open Science Framework Registries ( https://doi.org/10.17605/OSF.IO/AT6FC ).

Examining trauma, anxiety, and depression as predictors of dropout from residential treatment for substance use disorders.

Substance use disorders (SUDs) are highly prevalent and have deleterious effects on one's health and well-being. Inpatient treatment for SUDs reduces patient relapse, which subsequently ameliorates these negative effects on the individual and society. Additionally, those who complete treatment are less likely to relapse compared to those who do not complete treatment. Thus, maintaining patient engagement in treatment and reducing the rates of those leaving against medical advice (AMA) is particularly important. Examining the factors and comorbidities that may contribute to treatment dropout has the potential to identify at-risk patients in need of additional individualized intervention. The current study aimed to examine comorbid anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms as predictors of dropout AMA in a residential substance use treatment population. Results showed that patients with social anxiety were more likely to leave treatment AMA, while those with PTSD were more likely to complete treatment. Findings suggest that PTSD-specific treatment, as offered in this facility, may help with patient retention, while group focused therapy may be distressing to those with social anxiety. Clinical implications of this research may include incorporating evidence-based practice for social anxiety early during inpatient treatment to reduce anxiety such that patients may better engage with SUDs treatment.

The role of referral pathway to early intervention services for psychosis on 2-year inpatient and emergency service use.

This study examined the relationship between terminal referral source and subsequent urgent health service use in a Canadian early intervention service (EIS) for psychosis. Administrative health record data of emergency and inpatient mental health service use over a 2-year follow up from entry to EIS were retrospectively analyzed (n = 515). Negative binomial regression models were used to assess for the relationship between referral source and care outcomes. Compared to those referred from primary care services, the rate of urgent health care use was significantly greater for individuals referred to early intervention services from urgent care services while accounting for social and occupational functioning and psychotic symptom severity. Findings suggest that those referred from urgent services may be at an increased risk for subsequent urgent health care use while attending EIS for psychosis. Further research examining this relationship while incorporating additional relevant predictors is needed.

Behavioral weight management use in the Veterans Health Administration: Sociodemographic and health correlates.

INTRODUCTION: Over 40 % of United States Veterans Health Administration (VHA) primary care patients have obesity. Few patients use VHA's flagship weight management program, MOVE! and there is little information on other behavioral weight management program use. METHODS: The national United States cohort included over 1.5 million primary care patients with obesity, age 18-79, based on VHA administrative data. Gender stratified multivariable logistic regression identified correlates of weight management use in the year after a patient's first primary care appointment (alpha of 0.05). Weight management use was defined as MOVE! or nutrition clinic visits. RESULTS: The cohort included 121,235 women and 1,521,547 men with 13 % and 7 % using weight management, respectively. Point estimates for specific correlates of use were similar between women and men, and across programs. Black patients were more likely to use weight management than White patients. Several physical and mental health diagnoses were also associated with increased use, such as sleep apnea and eating disorders. Age and distance from VHA were negatively associated with weight management use. CONCLUSIONS: When assessing multiple types of weight management visits, weight management care in VHA appears to be used more often by some populations at higher risk for obesity. Other groups may need additional outreach, such as those living far from VHA. Future work should focus on outreach and prevention efforts to increase overall use rates. This work could also examine the benefits of tailoring care for populations in greatest need.

Engaging Black youth in depression and suicide prevention treatment within urban schools: study protocol for a randomized controlled pilot.

BACKGROUND: Depression continues to be an ongoing threat to adolescent well-being with Black adolescents being particularly vulnerable to greater burdens of depression as well as lower mental health service utilization. Black adolescents are likely to have untreated depression due to social network influences, varied perceptions of services and providers, or self-stigma associated with experiencing depressive symptoms. Furthermore, if or when treatment is initiated, low engagement and early termination are common. To address this gap, a trial is being conducted to preliminarily test the effectiveness of an engagement intervention targeting Black adolescents with depression in school mental health services in New York City. METHODS: A total of 60 Black middle and high school adolescents displaying depressive symptoms are equally randomized (based on school site) to the treatment arms. Both trial arms deliver Interpersonal Psychotherapy for Depressed Adolescents (IPT-A), a time-limited, evidence-based treatment for depression. Additionally, one arm pairs IPT-A with a brief, multi-level engagement intervention, the Making Connections Intervention (MCI), involving adolescents, caregivers, and clinicians. Outcomes of interest are group differences in depression and suicide ideation, adolescent and caregiver engagement, and mental health service use. DISCUSSION: This trial will serve as an efficacy assessment of the MCI among a sample of Black adolescent students with depressive symptoms. Clinical and implementation results will be used to inform future research to further test the MCI intervention in a larger sample. TRIAL REGISTRATION: Registered by ClinicalTrials.gov on May 3, 2019, identifier: NCT03940508.

Psychotherapist perceptions of engagement-building behaviours with youth clients across developmental levels.

Building a positive therapeutic relationship is a challenging, yet critical, first step in conducting youth psychotherapy. A number of studies in the youth treatment literature have indicated that a positive therapeutic alliance is related to increased treatment attendance, participation, and outcome. Some research has examined therapist behaviours for engaging therapy clients; however, developmental differences in alliance formation have had limited exploration. The current study surveyed clinicians about their use of specific engagement strategies and the developmental stage of their youth clients. It was hypothesised that participants would differentially rate the importance of different aspects of therapeutic engagement based upon a youth client's developmental stage and that these would correspond with differences in specific engagement strategies. A total of 64 clinicians with experience treating youth completed the study. The participants completed a questionnaire administered online that asked them to rate the importance of developmental differences to forming a therapeutic relationship and provide example client behaviours from their clinical experience for each developmental stage. Results showed clinicians felt the relative importance of collaboration, advocacy, and trustworthiness increased with age. These differences were also evidenced in the specific strategies clinicians endorsed in relation to each engagement factor across developmental stages. This program of research will eventually aid in the development of new guidelines for engaging clients in youth psychotherapy. In addition, the results may be used to enhance psychotherapy training for those working with children and adolescents.

First-contact patients with a community mental health service in rural Greece: A 3-year prospective study of treatment attendance and its co-relations.

BACKGROUND: Treatment continuation is essential for the optimal management of patients with mental disorders in the community, but treatment and outcome are often undermined by the high rates of service disengagement and treatment non-adherence across all psychiatric diagnoses. The phenomenon may be even more relevant in rural settings. AIMS: The aim of the present study was to explore attendance to treatment in first-contact patients in a community-based treatment setting in rural Greece and to explore the associations of treatment attendance with demographic and clinical factors. METHOD: Data were collected prospectively over a 3-year period, with 1-year follow-up interval. All first-contact cases with the Mobile Mental Health Unit of the prefectures of Ioannina and Thesprotia (MMHU I-T), Northwest Greece were considered, but only clinical cases were processed. RESULTS: The sample size consisted of 446 patients, with a mean age 65.4 ± 18.8 years. The rate of 12-month attendance to mental health treatment was 13.5% (60 out of 446 patients). Treatment attendance was found to be correlated with younger age, the diagnosis of schizophrenia-spectrum disorder, and patients' referral by other psychiatric services. First examination over the year 2019 had been significantly inversely associated with treatment engagement. CONCLUSION: Rates of subsequent attendance after initial assessment in a rural community mental healthcare setting were rather low in the present study. Several variables that have been previously associated with service engagement were found to be related in this study too, whereas other were not. Research on treatment engagement in rural treatment settings should be ongoing to reveal all associated factors.

Parental Cognitions, Treatment Engagement, and Child Outcomes of ADHD Behavioral Treatment among Asian American Families.

Asian American (AA) families remain critically underrepresented in clinical trials for ADHD interventions. Little is known about AA families' engagement in and outcomes of behavioral treatment (BT). Comparing AA families to other minoritized (OM) families and White families, this study examined parental cognitions, treatment engagement, and child outcomes of BT for ADHD inattentive type (ADHD-I). Path analyses were conducted utilizing data from a randomized controlled trial of BT for ADHD-I (N = 199 children, ages 7-11). Racial/ethnic differences in pretreatment parental self-competence and treatment expectations were examined for AA (n = 29) compared to OM (n = 35) and White (n = 135) parents. Two additional path models were conducted to examine the relations among race/ethnicity, pretreatment parental cognitions, treatment engagement, and posttreatment child outcomes. Direct effects of race/ethnicity and parental cognitions on posttreatment child outcomes as well as their indirect effects via treatment engagement were estimated. At pretreatment, AA parents endorsed lower parental self-competence and treatment expectations compared to OM and White parents. At posttreatment, AA parents reported fewer improvements in ADHD symptoms than White parents and lower global psychosocial improvement than OM parents. For all parents, treatment expectations positively predicted parent- and observer-rated treatment engagement, which in turn predicted child global psychosocial improvement. Path analyses indicated that the relationship between treatment expectations and posttreatment child global improvement was fully mediated by treatment engagement. These findings suggest that treatment expectations impede AA parents' engagement and success in BT. Implications for cultural adaptations of BT to improve AA families' treatment experience are discussed.

Association between comorbid chronic pain or prior hospitalization for mental illness and substance use treatment among a cohort at high risk of opioid overdose.

INTRODUCTION: Chronic pain and serious mental illness increase risk of opioid use, and opioid use can exacerbate both conditions. Substance use disorder (SUD) treatment can be lifesaving, but chronic pain and serious mental illness may make recovery challenging. We evaluated the association between current chronic pain and prior hospitalization for mental illness and 90-day SUD treatment engagement, among emergency department (ED) patients at high risk of opioid overdose. METHODS: We conducted a cohort analysis of 648 ED patients enrolled in a randomized controlled trial in Rhode Island. We linked baseline study data on chronic pain and prior hospitalization for mental illness to statewide administrative data on state-licensed treatment programs (including methadone) and buprenorphine treatment via prescription. We defined treatment engagement as initiation of a state-licensed treatment program, transfer between state-licensed programs/providers, or a buprenorphine prescription (re-)fill. We used modified Poisson models to estimate the association between each baseline comorbidity and treatment engagement within 90 days following the ED visit, adjusted for a priori potential confounders. In an exploratory analysis, models were stratified by baseline treatment status. RESULTS: The mean age of participants was 37 years; 439 (68 %) were male, and 446 (69 %) had been recently unhoused. Overall, 278 participants (43 %) engaged in treatment within 90 days of the ED visit. Participants with prior hospitalization for mental illness were more likely to engage in treatment than those without (adjusted risk ratio [ARR] = 1.24, 95 % confidence interval [CI] = 1.01-1.53), although this association was only among those already accessing treatment at baseline (ARR = 1.58, 95 % CI = 1.10-2.27). Chronic pain was not associated with 90-day treatment engagement overall (ARR = 1.12, 95 % CI = 0.91-1.38) or within baseline treatment subgroups. CONCLUSIONS: Among ED patients at high risk of opioid overdose and accessing treatment at baseline, those with prior hospitalization for mental illness (but not chronic pain) were more likely to engage in treatment following the ED visit, which may reflect disproportionate initiation of additional treatment programs, transfer between programs/providers, or ongoing buprenorphine treatment. Touchpoints within the medical system should be leveraged to ensure that everyone, including those with serious mental illness, can access high-quality SUD treatment at the desired intensity level.

Ethnic Identity and Mechanisms of Mental Health Service Engagement Among Young Adults with Serious Mental Illnesses.

PURPOSE: Young adults from minoritized racial and ethnic groups have lower rates of engagement in treatment for serious mental illnesses (SMI). Previous research suggests a relationship between ethnic identity development and engagement in mental health services, but it remains unclear how a sense of belonging and attachment to one's racial and ethnic group influences participation in treatment among young adults with SMI. METHODS: Bivariate analyses and structural equation modeling (SEM) were used to examine whether ethnic identity was associated with treatment engagement (attendance and investment in treatment) and how ethnic identity might influence engagement through theoretical proximal mediators. Eighty-three young adults with SMI (95% from minoritized racial and ethnic groups) were recruited from four outpatient psychiatric rehabilitation programs and assessed at least 3 months after initiating services. RESULTS: Stronger ethnic identity was associated with greater investment in treatment but not with treatment attendance. The SEM analysis indicated that stronger ethnic identity may improve investment in treatment by enhancing hope (0.53, p < .05) and beliefs that mental health providers are credible (0.32, p < .05), and by increasing self-efficacy (-0.09, p < .05). Proximal mediators of engagement were associated with investment in treatment (hope and credibility, p < .05, and self-efficacy p = 0.055). CONCLUSIONS: Findings provide preliminary evidence of an empirical and theoretical relationship between ethnic identity development and engagement in treatment among young adults with SMI. Assessment and strengthening of a young person's ethnic identity may be a promising approach for improving their engagement in services and reducing inequities in their care.

Treatment Engagement as a Predictor of Therapy Outcome Following Cognitive Behaviour Therapy for Autistic Children.

PURPOSE: Active engagement in one's therapy is a key contributor to successful outcomes. Research on child engagement in cognitive behaviour therapy (CBT) has largely focused on youth without autism. This longitudinal study examined multiple indicators of child engagement in relation to outcomes for autistic children who took part in CBT for emotion regulation. METHOD: Data were collected from 60 autistic children who were between 8 and 13 years of age (86.7% male; Mage = 9.58 years, SD = 1.44 years; 75% White). Indicators of child engagement included independent observer ratings of in-session involvement, as measured by the Child Involvement Rating Scale, and therapist ratings of the therapeutic relationship and homework completion using single-item measures. Indicators of engagement were measured at early (i.e., first third), middle (i.e., mid third), and late (i.e., final third) stages of treatment. Parent-reported emotion regulation was the primary treatment outcome, as measured by the Emotion Regulation Checklist. RESULTS: After controlling for pre-treatment scores, in-session involvement significantly predicted some aspects of post-treatment emotion regulation, whereas therapeutic relationship and homework completion did not. CONCLUSIONS: Child in-session involvement throughout therapy may be particularly relevant for treatment change. Addressing issues related to in-session involvement early in treatment may help to promote therapeutic success for autistic children.
