Abstract
This article aimed to provide a systematic narrative synthesis of existing studies on the mediators of change in psychotherapy with adolescents (10-19 years) and transition age youth (TAY) (20-29 years) who have experienced trauma-related symptoms or posttraumatic disorder. Additionally, we were interested in identifying psychotherapy-, trauma type-, and clients' age- and gender-specific mediators of treatment outcome. Following the preferred reporting items for systematic reviews and meta-analyses, a total of 3,723 studies published in PubMed and PsycINFO databases were screened against inclusion criteria, revealing 15 eligible studies. No studies with only TAY were found; therefore, all results were limited to therapy with adolescents. Cognitive mediators were tested in 66% of selected studies, followed by parents/family-related, mental-health-related, therapy-related, and behavioral mediators. Moderate evidence was found for posttraumatic cognitions, whereas therapeutic alliance seemed to be a promising candidate for future research. Striking absence of non-cognitive-behavioral therapy interventions, emotional and adolescent-specific mediators, as well as studies with males and in non-Western societies was evident. Future original studies would benefit from applying methodological rigor in respect to mediation testing.

Abstract
We conducted a dismantling design treatment study comparing individual CBT, CBT targeting parents' reinforcement skills (CBT+Reinf), and CBT targeting parents' relationship skills (CBT+ Relat) in 341 youths with primary anxiety diagnoses. At posttreatment, youths in CBTs with parent involvement had lower anxiety than youths in CBT. At 12-month follow-up, youths in CBT+Relat maintained lower anxiety relative to CBT. At posttreatment, negative reinforcement was significantly lower in CBT+Reinf than CBT+Relat and CBT; negative reinforcement partially mediated youth anxiety reduction. Reducing parental negative reinforcement in CBT+Reinf was associated with lower parental psychological control which also partially mediated youth anxiety reduction. Some of these mediational dynamics continued through follow-up. Targeting concrete behavioral parenting skills, especially negative reinforcement, produced treatment specificity and partial mediation relative to less concrete targeting, and enhanced CBT. Findings highlight complexities in identifying mechanisms through which targeting of parenting skills produces youth anxiety reduction and suggest avenues for future research.

Abstract
BACKGROUND Digital health interventions (DHIs) are efficacious for several mental disorders in youth; however, integrated, evidence-based knowledge about the mechanisms of change in these interventions is lacking. OBJECTIVE This systematic review aims to comprehensively evaluate studies on mediators and mechanisms of change in different DHIs for common mental disorders in children and adolescents. METHODS A systematic literature search of the electronic databases Cochrane Central Register of Controlled Trials, Embase, MEDLINE, and PsycINFO was conducted, complemented by backward and forward searches. Two independent reviewers selected studies for inclusion, extracted the data, and rated the methodological quality of eligible studies (ie, risk of bias and 8 quality criteria for process research). RESULTS A total of 25 studies that have evaluated 39 potential mediators were included in this review. Cognitive mediators were the largest group of examined intervening variables, followed by a broad range of emotional and affective, interpersonal, parenting behavior, and other mediators. The mediator categories with the highest percentages of significant intervening variables were the groups of affective mediators (4/4, 100%) and combined cognitive mediators (13/19, 68%). Although more than three-quarters of the eligible studies met 5 or more quality criteria, causal conclusions have been widely precluded. CONCLUSIONS The findings of this review might guide the empirically informed advancement of DHIs, contributing to improved intervention outcomes, and the discussion of methodological recommendations for process research might facilitate mediation studies with more pertinent designs, allowing for conclusions with higher causal certainty in the future.

Abstract
BACKGROUND Social communication interventions benefit children with ASD in early childhood. However, the mechanisms behind such interventions have not been rigorously explored. This study examines the mechanism underlying a naturalistic developmental behavioral intervention, JASPER (Joint Attention, Symbolic Play, Engagement, and Regulation), delivered by educators in the community. Specifically, the analyses focus on the mediating effect of joint engagement on children's initiations of joint attention (IJA) skills and whether IJA postintervention are associated with later gains in children's receptive and expressive language. METHODS One hundred seventy-nine children, age 2-5 years, were randomized to immediate JASPER treatment or waitlist (treatment as usual) control. Independent assessors blinded to time and treatment coded children's time jointly engaged and IJA during a 10-min teacher-child interaction at baseline, exit, and follow-up. Age-equivalent receptive and expressive language scores from the Mullen Scales of Early Learning were collected at baseline and follow-up. Mediation analyses with linear mixed models were used to explore the potential mediating effect of joint engagement on IJA. RESULTS Joint engagement significantly mediated 69% of the intervention effect on young children's IJA and IJA predicted improvements in standardized language scores. CONCLUSIONS Small but sustained changes in child-initiated joint engagement improved IJA, a core challenge in children with ASD, which in turn led to improvements in language.

Abstract
The Coping Cat protocol has shown both efficacy and effectiveness in the treatment of youth anxiety across numerous randomized controlled trials (RCTs), leading to its designation as an empirically supported treatment. The treatment is completed in two phases. In the first phase, children are taught a series of coping skills outlined using the FEAR plan acronym. The FEAR plan is then practiced in exposure tasks during the second phase of treatment. To illustrate implementation of both phases, and highlight core treatment components (i.e., exposure, flexibility within fidelity), a case description is presented. Directions for future research are discussed.

Abstract
Introduction Anxiety and depressive disorders are a significant problem that starts in childhood or adolescence and should be addressed early to avoid chronic mental conditions. There is strong evidence to demonstrate that psychological treatments are effective for these disorders, however, little is known on mediators and mechanisms of change of psychological treatment in adolescents and young adults. Understanding the pathways through which psychological treatments operate will facilitate more effective treatments. Aim We aim to conduct a systematic review, exploring the available evidence on mediators of psychological treatments for anxiety and depression in adolescents and young adults. Methods A systematic search has been performed on PubMed and PsycINFO databases to identify studies from inception to 23rd February 2020. Eligible studies include randomized controlled trials and trials (quasi-experimental) designs that have enrolled adolescents and young adults presenting with depression and/or anxiety and that have examined mediators of psychological treatments. A group of 20 reviewers from the COST-Action TREATme (CA16102) divided into 10 pairs independently screen studies for inclusion, extract information from the included studies, and assess the methodological quality of the included studies and the requirements for mediators. The methodological quality will be assessed by The Mixed Methods Appraisal Tool. Extracted data from the included studies will be collected and presented using a narrative approach. Discussion This systematic review will summarize and provide a comprehensive overview of the current evidence on mediators of psychological treatments for anxiety and depression for adolescents and young adults. Results will allow the identification of strategies to optimize intervention to enhance clinical outcomes. Ethics and dissemination Ethics approval is not required. Findings from this systematic review will be published in a peer-reviewed journal and disseminated at conferences and meetings. PROSPERO registration number: CRD42021234641.

A Sequential Multiple Assignment Randomized Trial (SMART) study of medication and CBT sequencing in the treatment of pediatric anxiety disorders. BMC Psychiatry 2021; 21:323.

Abstract
BACKGROUND Treatment of a child who has an anxiety disorder usually begins with the question of which treatment to start first, medication or psychotherapy. Both have strong empirical support, but few studies have compared their effectiveness head-to-head, and none has investigated what to do if the treatment tried first isn't working well-whether to optimize the treatment already begun or to add the other treatment. METHODS This is a single-blind Sequential Multiple Assignment Randomized Trial (SMART) of 24 weeks duration with two levels of randomization, one in each of two 12-week stages. In Stage 1, children will be randomized to fluoxetine or Coping Cat Cognitive Behavioral Therapy (CBT). In Stage 2, remitters will continue maintenance-level therapy with the single-modality treatment received in Stage 1. Non-remitters during the first 12 weeks of treatment will be randomized to either [1] optimization of their Stage 1 treatment, or [2] optimization of Stage 1 treatment and addition of the other intervention. After the 24-week trial, we will follow participants during open, naturalistic treatment to assess the durability of study treatment effects. Patients, 8-17 years of age who are diagnosed with an anxiety disorder, will be recruited and treated within 9 large clinical sites throughout greater Los Angeles. They will be predominantly underserved, ethnic minorities. The primary outcome measure will be the self-report score on the 41-item youth SCARED (Screen for Child Anxiety Related Disorders). An intent-to-treat analysis will compare youth randomized to fluoxetine first versus those randomized to CBT first ("Main Effect 1"). Then, among Stage 1 non-remitters, we will compare non-remitters randomized to optimization of their Stage 1 monotherapy versus non-remitters randomized to combination treatment ("Main Effect 2"). The interaction of these main effects will assess whether one of the 4 treatment sequences (CBT➔CBT; CBT➔med; med➔med; med➔CBT) in non-remitters is significantly better or worse than predicted from main effects alone. DISCUSSION Findings from this SMART study will identify treatment sequences that optimize outcomes in ethnically diverse pediatric patients from underserved low- and middle-income households who have anxiety disorders. TRIAL REGISTRATION This protocol, version 1.0, was registered in ClinicalTrials.gov on February 17, 2021 with Identifier: NCT04760275 .

Abstract
Parent- and family-level correlates of youth anxiety are well-documented, and they highlight potential targets for family-focused intervention. Although family-based approaches for treating youth anxiety generally are considered efficacious for achieving symptom reduction, they vary in format and approach and it remains unclear whether they offer an advantage over individual child treatment. To better understand the current state of the evidence, we used meta-analytic methods to examine the therapeutic approaches described in existing family interventions for child and adolescent anxiety, whether they mapped to the major mechanisms proposed in the literature, and the timeline along which relevant parent/family variables were measured. We examined how these mechanism-focused family interventions performed in RCTs relative to individual child CBT and whether they shifted symptoms and relevant parenting behaviors. A total of 11 randomized controlled trials (RCTs) compared individual cognitive behavior therapy (CBT) to CBT+ a family component (CBT + FAM) and included a youth anxiety measure at pre- and post-treatment; only half of these (n=6) also included a parent/family functioning measure at both pre- and post-treatment (across both primary and secondary outcome papers). Only a single study included anxiety measures at a mid-treatment time point, and none included parent measures at a mid-treatment time point. Findings are discussed in terms of design considerations and advancing the field of family intervention for youth anxiety.

Abstract
Prevention studies typically focus on outcome variables such as reductions in problem behavior, rather than targeted factors (e.g., cognitions), or the relation between change in targeted factors and outcomes. Therefore, the current study examined the effect of a targeted prevention program for childhood disruptive behavior on targeted factors (i.e., perspective taking and self-control) and associations between change in targeted factors and outcomes (i.e., aspects of disruptive behavior). The sample consisted of 173 children (Mage = 10.2 years) who were randomly assigned to an intervention condition (n = 70) or waitlist control condition (n = 103). Assessment took place at pre-, post- and follow-up measurements. For ethical considerations, follow-up data was not available for children on the waitlist. Findings revealed a direct intervention effect on self-control. From pre-test to follow-up, children who received the intervention improved in perspective taking and self-control. Moreover, improvements in self-control were associated with and predicted reductions in teacher-reported symptoms of oppositional defiant disorder. No associations were found between changes in perspective taking and disruptive behavior. These findings suggest that self-control may be an important target factor in reducing childhood disruptive behavior in targeted prevention.

Abstract
A growing number of evidence-based systemic treatments for adolescents with disruptive behaviour problems exist. However, it is not clear to what extent these treatments have unique and common elements. Identification of common elements in the different treatments would be beneficial for the further understanding and development of family-based interventions, training of therapists, and research. Therefore, the aim of this Review was to identify common elements of evidence-based systemic treatments for adolescents with disruptive behaviour. Several common elements of systemic treatments were identified, showing a strong overlap between the interventions. Investigation of these common mechanisms and techniques could potentially build strong universal systemic treatment and training modules for a broad spectrum of adolescents with problem behaviours.

Understanding mechanisms of change: An unpacking study of the evidence-based common-elements treatment approach (CETA) in low and middle income countries. Behav Res Ther 2019; 130:103430.

Abstract
There is a recognized need to better understand "essential ingredients" of psychological treatments, and refine interventions to be more scalable and sustainable. The goal of the present study was to look within a specific modular, flexible, multi-problem transdiagnostic psychological intervention -the Common Elements Treatment Approach (CETA) - and examine questions that would lead to optimizing CETA for scale up and sustainment. Utilizing data from two trials of CETA in two different countries (Thailand and Iraq), this manuscript aims to: 1) determine the "active treatment dose" or how many sessions are needed to achieve clinically meaningful change overall, in CETA); and 2) test how trajectories of client symptom change varied based on client characteristics and/or on delivery of certain elements. Results showed that overall 50% of CETA clients show some improvement after 4-6 sessions (1 SD) and large improvement (2 SD) after 7-10 sessions. Trajectories of change show steady symptom decline over time. Results support gradual exposure as one of the "active ingredients". Findings suggest that modular, flexible transdiagnostic models may allow for more efficient, targeted treatment as we gain more knowledge about key ingredients, their timing within treatment, and client outcomes.

Abstract
Objective Treatment specificity and long-term recovery mediation of peer-involvement group cognitive behavioral therapy (GCBT) and parent-involvement CBT (PCBT) were investigated for youth anxiety disorders. Method 240 youths with primary anxiety diagnoses participated in a randomized controlled efficacy trial. Youth anxiety and peer variables/mediators (positive peer-youth relationships; social skills), and parent variables/mediators (psychological control; negative parent-youth relationships) were assessed. Results At posttreatment and 12-month follow up, positive peer-youth relationships were significantly higher in GCBT than PCBT (specificity). At posttreatment, not follow up, parental psychological control was significantly lower in PCBT than GCBT (specificity). Parental psychological control and positive peer-youth relationships were putative mediators. The two CBTs produced similar anxiety reductions through different mechanisms. Conclusions CBT targets show specificity and mediation, providing insight into specific mechanisms through which GCBT and PCBT bring about anxiety reduction and guidance for streamlining these CBTs in practice.

Abstract
Despite increasing research and clinical interest in delivering psychosocial interventions for children affected by war, little research has been conducted on the underlying mechanisms of change associated with these interventions. This review aimed to identify these processes in order to inform existing interventions and highlight research gaps. A systematic review of reviews was conducted drawing from academic databases (PubMed, PILOTS, Cochrane Library for Systematic Reviews) and field resources (e.g. Médecins Sans Frontières and the Psychosocial Centre of the International Federation of Red Cross and Red Crescent Societies), with extracted data analysed using Thematic Content Analysis. Thirteen reviews of psychosocial or psychological interventions for children and adolescents (< 25 years old) affected by war, armed conflict or political violence were identified, covering over 30 countries worldwide. Qualitative analysis identified 16 mechanisms of change, one of which was an adverse mechanism. Themes included protection from harm, play, community and family capacity building, strengthening relationships with caregivers, improved emotional regulation, therapeutic rapport, trauma processing, and cognitive restructuring; with the adverse mechanism relating to the pathologising of normal reactions. However, only 4 mechanisms were supported by strong empirical evidence, with only moderate or poor quality evidence supporting the other mechanisms. The poor quality of supporting evidence limits what can be inferred from this review's findings, but serves to highlight clinically informed mechanisms of change for existing and widely used non-specialist interventions in the field, which urgently need rigorous scientific testing to inform their continued practice.

Abstract
Objective: Social-cognitive information processing, social skills, and social interactions are problem-maintaining variables for aggressive behavior in children. We hypothesized that these factors may be possible mediators of the mechanism of change in the child-centered treatment of conduct disorders (CDs). The aim of the present study (Clinical trials.gov Identifier: NCT01406067) was to examine putative mechanisms of change for the decrease in oppositional-defiant behavior resulting from child-centered treatment of patients with oppositional-defiant disorder (ODD) or CD. Method: 91 children (age 6-12 years) with ODD/CD were randomized to receive either social skills training or to a resource activating play group. Mediator analyses were conducted using path analyses. Results: The assumed mediating effects were not significant. However, alternative models with the putative mediators and outcome in reversed positions showed significant indirect effects of the oppositional-defiant symptoms as mediator for the decrease of disturbance of social-information processing, social skills, and social interactions. Conclusions: The proposed model for mechanisms of change could not be confirmed, with the results pointing to a reversed causality. Variables other than those hypothesized must be responsible for mediating the effects of the intervention on child oppositional-defiant behavior. Possible mechanisms of change were discussed.

Abstract
OBJECTIVE This study aims to identify key process variables that are associated with changes in alcohol consumption and mental health symptoms over 12months following personality-targeted interventions in youth. METHOD 154 high-risk youth (aged 12-13years) in 7 Montreal high schools were identified using the Substance Use Risk Profile Scale and participated in personality-matched interventions. Preliminary process variables were identified using a combination of psychotherapy process variables and youth-generated (qualitative) feedback immediately post-intervention. RESULTS Learning, skill development and a positive group experience were key to positive behavioural change. Youth-generated feedback independently accounted for 12-25% of the variance in the change in alcohol use and mental health symptoms over 12months. Changes in cognitive distortions and self-esteem accounted for somewhat less of the variance in alcohol use (0-9%), but a moderate-to-large portion of the variance in changes in mental health symptoms (up to 44%). CONCLUSIONS The study findings highlight candidate process variables relevant to future implementations of this program that might inform change processes relevant to brief interventions with youth more generally. This study suggests that youth experiences can indicate proximal measures of program efficacy, and has implications for the dissemination of this brief intervention program.

Abstract
How do psychological therapies work? How can we enhance treatment to improve outcomes? Questions of mediation lie at the heart of these inquiries. However, within the child and adolescent treatment literature, studies of mediation often rely on methodological and statistical approaches that limit the inferences that can be drawn from study findings. This future directions review delineates some of these issues and suggests improvements through two interrelated paths. We propose that mediation studies in the youth treatment literature will be enhanced (a) by adopting best practices in nomothetic (group-based) methodologies for assessing putative mediating variables and conducting appropriate statistical analyses and (b) by increasing the use of idiographic (individual-focused) approaches to youth outcome research through mediation studies that use innovative designs, data collection techniques, and analytic methods. We discuss the applicability of findings using these approaches to the treatment of youth in particular.

Abstract
Extending previous reviews related to cultural responsiveness in the treatment of ethnic minority youth, the current review provides a critical assessment and synthesis of both basic and applied research on the integration of three racial-ethnic protective factors (racial identity, racial socialization, Africentric worldview) in psychosocial prevention and intervention programs for Black children and adolescents. Seventeen programs meeting inclusion and exclusion criteria were evaluated for the extent to which racial-ethnic protective factors and related mechanisms were integrated, applied, and tested in such programs. A systematic assessment of these programs revealed that several prevention and intervention programs drew upon the three factors, particularly Africentric worldview. In addition, a number of studies hypothesized and assessed mechanisms, both those previously identified in conceptual literature and those that emerged from the interventions themselves. A set of recommendations encouraging the implementation of these factors into future prevention and intervention programs, examples of how clinicians can infuse these factors into psychotherapy, and areas for future research are discussed.

Abstract
We tested the effectiveness of the preventive behavioral parent training (BPT) program, The Incredible Years (IY), and the independent effects of previously suggested sociodemographic and intervention-based moderator variables (i.e., initial severity of externalizing problem behavior, child gender, social economic status, family composition, and number of sessions parents attended), in a large-scale randomized controlled trial. Questionnaire and observation data from 387 parents and children ages 4-8 years (Mage= 6.21, SD = 1.33, 55.30% boys) across pretest, posttest, and 4-month follow-up were analyzed, using full intention-to-treat analyses and correcting for multiple testing. IY was successful in decreasing parent-reported child externalizing behavior (Cohen's d = 0.20 at posttest, d = 0.08 at follow-up), increasing parent-reported (d = 0.49, d = 0.45) and observed (d = 0.06, d = 0.02) positive parenting behavior, and decreasing parent-reported negative parenting behavior (d = 0.29, d = 0.25). No intervention effects were found for reported and observed child prosocial behavior, observed child externalizing behavior, and observed negative parenting behavior. Out of 40 tested moderation effects (i.e., 8 Outcomes × 5 Moderators), only three significant moderation effects appeared. Thus, no systematic evidence emerged for moderation of IY effects. The present multi-informant trial demonstrated that many previously suggested moderators might not be as potent in differentiating BPT effects as once thought.

Abstract
Parenting and family interventions have repeatedly shown effectiveness in preventing and treating a range of youth outcomes. Accordingly, investigators in this area have conducted a number of studies using statistical mediation to examine some of the potential mechanisms of action by which these interventions work. This review examined from a methodological perspective in what ways and how well the family-based intervention studies tested statistical mediation. A systematic search identified 73 published outcome studies that tested mediation for family-based interventions across a wide range of child and adolescent outcomes (i.e., externalizing, internalizing, and substance-abuse problems; high-risk sexual activity; and academic achievement), for putative mediators pertaining to positive and negative parenting, family functioning, youth beliefs and coping skills, and peer relationships. Taken as a whole, the studies used designs that adequately addressed temporal precedence. The majority of studies used the product of coefficients approach to mediation, which is preferred, and less limiting than the causal steps approach. Statistical significance testing did not always make use of the most recently developed approaches, which would better accommodate small sample sizes and more complex functions. Specific recommendations are offered for future mediation studies in this area with respect to full longitudinal design, mediation approach, significance testing method, documentation and reporting of statistics, testing of multiple mediators, and control for Type I error.

Abstract
Anxiety and depression are highly comorbid and share several common etiological processes. Therefore, it may be more efficient to develop interventions that treat or prevent these problems together rather than as separate entities. The present meta-analytic review examined whether interventions for children and adolescents that explicitly targeted either anxiety or depression showed treatment specificity or also impacted the other outcome (i.e. cross-over effects). We addressed this question both within the same type of study (i.e. treatment, prevention) and across study types. Only randomized controlled trials (RCTs) that assessed both constructs with dimensional measures were included in this review. For treatment studies, RCTs targeting anxiety (n = 18) showed significant effects on both anxious and depressive symptoms, although more strongly on anxiety than depression; similarly, RCTs treating depression (n = 9) yielded significant effects on both depressive and anxious symptoms, but stronger effects on depression than anxiety. Thus, there were cross-over effects in treatments purportedly targeting either anxiety or depression, and also treatment specificity, such that larger effects were seen for the target problem at which the treatment was aimed. Anxiety prevention studies (n = 14) significantly affected anxious, but not depressive symptoms, indicating no cross-over effect of anxiety prevention trials on depression. For depression prevention studies (n = 15), the effects were not significant for either depressive or anxiety symptoms, although the effect was significantly larger for depressive than for anxious symptoms. Post-hoc analyses revealed that the effect on depressive symptoms was significant in depression preventions trials of targeted but not universal samples. Implications for transdiagnostic interventions are discussed.

Abstract
Mediation analyses can identify mechanisms of change in Cognitive-Behavioral Therapy (CBT). However, few studies have analyzed mediators of CBT for youth internalizing disorders; only one trial evaluated treatment mechanisms for youth with mixed mood diagnoses. This study evaluated mediators in the randomized trial of Child- and Family-Focused CBT (CFF-CBT) versus Treatment As Usual (TAU) for pediatric bipolar disorder (PBD), adjunctive to pharmacotherapy. Sixty-nine children ages 7-13 with PBD were randomly assigned to CFF-CBT or TAU. Primary outcomes (child mood, functioning) and candidate mediators (family functioning, parent/child coping) were assessed at baseline and 4-, 8-, 12- (post-treatment), and 39-weeks (follow-up). Compared with TAU, children receiving CFF-CBT exhibited greater improvement in mania, depression, and global functioning. Several parent and family factors significantly improved in response to CFF-CBT versus TAU, and were associated with the CFF-CBT treatment effect. Specifically, parenting skills and coping, family flexibility, and family positive reframing showed promise as mediators of child mood symptoms and global functioning. Main or mediating effects for youth coping were not significant. CFF-CBT may impact children's mood and functioning by improving parenting skills and coping, family flexibility, and family positive reframing. Findings highlight the importance of parent coping and family functioning in the treatment of PBD.

Abstract
Understanding mechanisms and active ingredients of intervention is critical to training clinicians, particularly when interventions are transported from laboratories to communities. One promising active ingredient of parenting programs is clinicians' in vivo feedback regarding parent-child interactions. The present study examined whether a form of in vivo feedback, in the moment commenting, predicted treatment retention and parent behavior change when the Attachment and Biobehavioral Catch-up (ABC) intervention was implemented in a community setting. Observational data were collected from 78 parent-child dyads (96% mothers; M age = 29 years; 81% minority; infants' M age = 12 months; 90% minority) across 640 sessions conducted by 9 clinicians (100% female, M age = 39; 67% minority) in Hawaii. Parental behavior was assessed with a semistructured play task before and after intervention. Clinicians' in-the-moment feedback to parents was assessed from intervention session videos. Clinicians' frequency and quality of in-the-moment feedback predicted change in parental intrusiveness and sensitivity at posttreatment. Frequency of in-the-moment feedback also predicted likelihood of retention. Hierarchical linear modeling demonstrated strong support for these associations at the between-clinician level, and limited additional support at the within-clinician (i.e., between-case) level. Thus, a hypothesized active ingredient of treatment, in-the-moment feedback, predicted community-based ABC outcomes. The results complement lab-based evidence to suggest that in vivo feedback may be a mechanism of change in parenting interventions. Helping clinicians to provide frequent, high-quality in vivo feedback may improve parenting program outcomes in community settings.

Abstract
Objective: Survival time is an important type of outcome variable in treatment research. Currently, limited guidance is available regarding performing mediation analyses with survival outcomes, which generally do not have normally distributed errors, and contain unobserved (censored) events. We present considerations for choosing an approach, using a comparison of semi-parametric proportional hazards (PH) and fully parametric accelerated failure time (AFT) approaches for illustration. Method: We compare PH and AFT models and procedures in their integration into mediation models and review their ability to produce coefficients that estimate causal effects. Using simulation studies modeling Weibull-distributed survival times, we compare statistical properties of mediation analyses incorporating PH and AFT approaches (employing SAS procedures PHREG and LIFEREG, respectively) under varied data conditions, some including censoring. A simulated data set illustrates the findings. Results: AFT models integrate more easily than PH models into mediation models. Furthermore, mediation analyses incorporating LIFEREG produce coefficients that can estimate causal effects, and demonstrate superior statistical properties. Censoring introduces bias in the coefficient estimate representing the treatment effect on outcome—underestimation in LIFEREG, and overestimation in PHREG. With LIFEREG, this bias can be addressed using an alternative estimate obtained from combining other coefficients, whereas this is not possible with PHREG. Conclusions: When Weibull assumptions are not violated, there are compelling advantages to using LIFEREG over PHREG for mediation analyses involving survival-time outcomes. Irrespective of the procedures used, the interpretation of coefficients, effects of censoring on coefficient estimates, and statistical properties should be taken into account when reporting results.

Abstract
BACKGROUND Within the past decade, health care service and research priorities have shifted from evidence-based medicine to personalized medicine. In mental health care, a similar shift to personalized intervention may boost the effectiveness and clinical utility of empirically supported therapies (ESTs). The emerging science of personalized intervention will need to encompass evidence-based methods for determining which problems to target and in which order, selecting treatments and deciding whether and how to combine them, and informing ongoing clinical decision-making through monitoring of treatment response throughout episodes of care. We review efforts to develop these methods, drawing primarily from psychotherapy research with youths. Then we propose strategies for building a science of personalized intervention in youth mental health. FINDINGS The growing evidence base for personalizing interventions includes research on therapies adapted for specific subgroups; treatments targeting youths' environments; modular therapies; sequential, multiple assignment, randomized trials; measurement feedback systems; meta-analyses comparing treatments for specific patient characteristics; data-mining decision trees; and individualized metrics. CONCLUSION The science of personalized intervention presents questions that can be addressed in several ways. First, to evaluate and organize personalized interventions, we propose modifying the system used to evaluate and organize ESTs. Second, to help personalizing research keep pace with practice needs, we propose exploiting existing randomized trial data to inform personalizing approaches, prioritizing the personalizing approaches likely to have the greatest impact, conducting more idiographic research, and studying tailoring strategies in usual care. Third, to encourage clinicians' use of personalized intervention research to inform their practice, we propose expanding outlets for research summaries and case studies, developing heuristic frameworks that incorporate personalizing approaches into practice, and integrating personalizing approaches into service delivery systems. Finally, to build a richer understanding of how and why treatments work for particular individuals, we propose accelerating research to identify mediators within and across RCTs, to isolate mechanisms of change, and to inform the shift from diagnoses to psychopathological processes. This ambitious agenda for personalized intervention science, although challenging, could markedly alter the nature of mental health care and the benefit provided to youths and families.

Abstract
OBJECTIVE Test changes in (a) coping efficacy and (b) anxious self-talk as potential mediators of treatment gains at 3-month follow-up in the Child/Adolescent Anxiety Multimodal Treatment Study (CAMS). METHOD Participants were 488 youth (ages 7-17; 50.4% male) randomized to cognitive-behavioral therapy (CBT; Coping cat program), pharmacotherapy (sertraline), their combination, or pill placebo. Participants met Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition (DSM-IV) criteria for generalized anxiety disorder, social phobia, and/or separation anxiety disorder. Coping efficacy (reported ability to manage anxiety provoking situations) was measured by youth and parent reports on the Coping Questionnaire, and anxious self-talk was measured by youth report on the Negative Affectivity Self-Statement Questionnaire. Outcome was measured using the Pediatric Anxiety Rating Scale (completed by Independent Evaluators blind to condition). For temporal precedence, residualized treatment gains were assessed at 3-month follow-up. RESULTS Residualized gains in coping efficacy mediated gains in the CBT, sertraline, and combination conditions. In the combination condition, some unique effect of treatment remained. Treatment assignment was not associated with a reduction in anxious self-talk, nor did anxious self-talk predict changes in anxiety symptoms. CONCLUSIONS The findings suggest that improvements in coping efficacy are a mediator of treatment gains. Anxious self-talk did not emerge as a mediator.

Transdiagnostic group behavioral activation and exposure therapy for youth anxiety and depression: Initial randomized controlled trial. Behav Res Ther 2015; 76:65-75.

Abstract
Anxiety and depression are debilitating and commonly co-occurring in young adolescents, yet few interventions are designed to treat both disorder classes together. Initial efficacy is presented of a school-based transdiagnostic group behavioral activation therapy (GBAT) that emphasizes anti-avoidance in vivo exposure. Youth (N = 35; ages 12-14; 50.9% male) were randomly assigned to either GBAT (n = 21) or WL (n = 14) after completing a double-gated screening process. Multi-reporter, multi-domain outcomes were assessed at pretreatment, posttreatment, and four-month follow-up (FU). GBAT was associated with greater posttreatment remission rates than WL in principal diagnosis (57.1% vs. 28.6%; X1(2) = 2.76, p = .09) and secondary diagnosis (70.6% vs. 10%; X1(2) = 9.26, p = .003), and greater improvement in Clinical Global Impairment - Severity ratings, B = -1.10 (0.42), p = .01. Symptom outcomes were not significantly different at posttreatment. GBAT produced greater posttreatment behavioral activation (large effect size) and fewer negative thoughts (medium effect), two transdiagnostic processes, both at the trend level. Most outcomes showed linear improvement from pretreatment to FU that did not differ depending on initial condition assignment. Sample size was small, but GBAT is a promising transdiagnostic intervention for youth anxiety and unipolar mood disorders that can feasibly and acceptably be applied in school settings.

Abstract
BACKGROUND Although both researchers and practitioners widely recognize therapeutic alliance's importance in general psychotherapy, studies specific to alcohol use treatments have produced mixed results and generally do not investigate if and how alliance changes over course of treatment. METHODS Using parallel process latent growth curve modeling, the authors examined if increase in alliance was associated with reduced drinking behaviors and a statistical mediator in the relationship between treatment modality and outcome. The authors used data from Project MATCH (J Stud Alcohol. 1997;58:7-29; Addiction. 1997;92:1671-1698), which investigated client-treatment matching effects for alcohol treatment among outpatient (n = 952) and aftercare (n = 774) participants randomized to cognitive behavioral treatment (CBT), 12-step facilitation (TSF), or motivational enhancement therapy (MET). RESULTS Results indicate therapist-rated alliance increased significantly for CBT and TSF participants, but not MET. Participants across modalities in both samples evidenced the largest decrease in drinking behaviors from baseline to midtreatment and a slight deterioration in treatment gains from midtreatment to 15 months posttreatment. Alliance did not mediate the relationship between treatment modality and outcome, but increase in alliance was significantly related to decrease in drinking frequency. CONCLUSIONS These findings provide further justification for researchers to specifically design studies to examine change in alliance as a mechanism of change in alcohol treatments.

Abstract
Change in parenting behavior is theorized to be the mediator accounting for change in child and adolescent externalizing problems in behavioral parent training (BPT). The purpose of this review is to examine this assumption in BPT prevention and intervention programs. Eight intervention and 17 prevention studies were identified as meeting all criteria or all but one criterion for testing mediation. Parenting behaviors were classified as positive, negative, discipline, monitoring/supervision, or a composite measure. Forty-five percent of the tests performed across studies to test mediation supported parenting as a mediator. A composite measure of parenting and discipline received the most support, whereas monitoring/supervision was rarely examined. More support for the mediating role of parenting emerged for prevention than intervention studies and when meeting all criteria for testing mediation was not required. Although the findings do not call BPT into question as an efficacious treatment, they do suggest more attention should be focused on examining parenting as a putative mediator in BPT.

Abstract
The prevalence of unmet health and mental health needs among youth has spurred the growing consensus to develop strategies that integrate services to promote overall well-being. This pilot study reports on the feasibility and outcomes of a theory-driven, family-focused, integrated health-mental health promotion program for underserved adolescents receiving school mental health services. Parent and adolescent assessments conducted prior to and following the brief, 6-session promotion program showed significant improvements in family support, youth self-efficacy, health behaviors, and mental health outcomes. Clinician reports contributed to a characterization of the feasibility, acceptability, and future recommendations for the integrated program.

Abstract
This paper describes the initial evaluation of the Therapist-Parent Interaction Coding System (TPICS), a measure of in vivo therapist coaching for the evidence-based behavioral parent training intervention, parent-child interaction therapy (PCIT). Sixty-one video-recorded treatment sessions were coded with the TPICS to investigate (1) the variety of coaching techniques PCIT therapists use in the early stage of treatment, (2) whether parent skill-level guides a therapist's coaching style and frequency, and (3) whether coaching mediates changes in parents' skill levels from one session to the next. Results found that the TPICS captured a range of coaching techniques, and that parent skill-level prior to coaching did relate to therapists' use of in vivo feedback. Therapists' responsive coaching (e.g., praise to parents) was a partial mediator of change in parenting behavior from one session to the next for specific child-centered parenting skills; whereas directive coaching (e.g., modeling) did not relate to change. The TPICS demonstrates promise as a measure of coaching during PCIT with good reliability scores and initial evidence of construct validity.

Abstract
In the current study, we examined longitudinal changes in, and bidirectional effects between, parenting practices and child behavior problems in the context of a psychosocial treatment and 3-year follow-up period. The sample comprised 139 parent-child dyads (child ages 6-11) who participated in a modular treatment protocol for early-onset ODD or CD. Parenting practices and child behavior problems were assessed at six time-points using multiple measures and multiple reporters. The data were analyzed using cross-lagged panel analyses. Results indicated robust temporal stabilities of parenting practices and child behavior problems, in the context of treatment-related improvements, but bidirectional effects between parenting practices and child behavior were less frequently detected. Our findings suggest that bidirectional effects are relatively smaller than the temporal stability of each construct for school-age children with ODD/CD and their parents, following a multi-modal clinical intervention that is directed at both parents and children. Implications for treatment and intervention are discussed.

Abstract
OBJECTIVE To study cardiac, sleep-related, and emotional reactions to playing violent (VG) versus nonviolent video games (NVG) in adolescents with different gaming habits. METHODS Thirty boys (aged 13-16 years, standard deviation = 0.9), half of them low-exposed (≤1 h/d) and half high-exposed (≥3 h/d) to violent games, played a VG/NVG for 2 hours during two different evenings in their homes. Heart rate (HR) and HR variability were registered from before start until next morning. A questionnaire about emotional reactions was administered after gaming sessions and a sleep diary on the following mornings. RESULTS During sleep, there were significant interaction effects between group and gaming condition for HR (means [standard errors] for low-exposed: NVG 63.8 [2.2] and VG 67.7 [2.4]; for high-exposed: NVG 65.5 [1.9] and VG 62.7 [1.9]; F(1,28) = 9.22, p = .005). There was also a significant interaction for sleep quality (low-exposed: NVG 4.3 [0.2] and VG 3.7 [0.3]); high-exposed: NVG 4.4 [0.2] and VG 4.4 [0.2]; F(1,28) = 3.51, p = .036, one sided), and sadness after playing (low-exposed: NVG 1.0 [0.0] and VG 1.4 [0.2]; high-exposed: NVG 1.2 [0.1] and VG 1.1 [0.1]; (F(1,27) = 6.29, p = .009, one sided). CONCLUSIONS Different combinations of the extent of (low versus high) previous VG and experimental exposure to a VG or an NVG are associated with different reaction patterns-physiologically, emotionally, and sleep related. Desensitizing effects or selection bias stand out as possible explanations.

Abstract
Studying moderators of intervention effects is essential to elucidate what works for whom. The present study investigated whether child personality moderates short–term and follow–up effects of an individualised preventive school–based intervention for children with externalising behaviour. The sample consisted of 48 schools, with 264 fourth–grade children displaying externalising behaviour (Mage = 10.2 years), randomly assigned to the intervention (n = 191) or no intervention control (n = 73) condition. Teachers and children reported at pretest, posttest and follow–up test about reactive and proactive aggression. Child personality was assessed by teachers at pretest. Child conscientiousness moderated short–term intervention effects, indicating that more organised and planful children benefited more from the intervention. Child extraversion moderated both short–term and follow–up intervention effects, with low extraverted children showing larger effects. These results affirm the importance of including personality as moderator of intervention effects in future studies, as interventions adapted to specific child traits might yield larger effects.

Abstract
Cognitive and behavioral therapies emphasize the importance of skill acquisition and use, and these skills are proposed to mediate treatment outcomes. Despite its theoretical importance, research on skill use as a mechanism of change in CBT and its measurement is still in its infancy. A search of online databases was conducted to identify and review the literature testing the meditational effect of CBT skills on treating depression in adults. Additionally, we reviewed the various methods to assess a patient's use of CBT skills. We identified 13 studies examining the frequency of CBT skill use and 11 studies examining the quality of CBT skill use. While the literature provides preliminary evidence for the mediational role of CBT skill use frequency and quality on depression treatment outcomes, methodological limitations in much of the existing literature prevent firm conclusions about the role of skills use on treatment outcomes.

Abstract
The aim of this literature review was to examine pre-treatment child and adolescent characteristics as predictors and moderators of outcome in psychotherapy treatment trials of anxiety and depressive disorders. A literature search was conducted using several databases and resulted in 45 published studies (32 anxiety studies and 13 depression studies) meeting predefined methodological criteria. Ten client demographic (age, gender, ethnicity, IQ) and clinical factors (duration, type of diagnosis, pre-treatment severity, comorbidity) were examined across studies. The majority of findings showed non-significant associations between demographic factors (gender and age) with treatment outcome for both the anxiety and the depression treatment trials. Some important differences between the results of the anxiety and depression treatment trials were found. The majority of findings for the anxiety studies suggest that there are no demographic or clinical factors that predict or moderate treatment outcome. For the depression studies, however, the findings suggest that baseline symptom severity and comorbid anxiety may impact on treatment response. Overall, existing studies of pre-treatment patient variables as predictors and moderators of anxiety and depression treatment outcome provide little consistent knowledge concerning for what type of patients and under what conditions treatments work. Suggestions for future research are discussed.

Abstract
With the current focus on increasing utilization of empirically supported treatments, knowledge of sample differences and similarities has increasing importance. The present study compared anxiety-disordered youth (age 7-13) from (a) five Norwegian service clinics (SC, N = 111) to (b) a university research clinic (RC) in Philadelphia, USA (N = 144) on pre-treatment characteristics measured by the Multidimensional Anxiety Scale for Children, Child Behavior Checklist, Teacher Report Form, Anxiety Disorders Interview Schedule, and Children's Global Assessment Scale (CGAS). SC youth demonstrated higher levels of anxiety based on child- (d = 0.42-1.04) and parent-report (d = 0.53) and conduct problems based on parent-report (d = 0.43) compared to RC youth. SC youth was more functionally impaired on the CGAS (d = 0.97), whereas RC youth evidenced a greater number of diagnoses (d = 0.63). The two samples were equivalent regarding parent-reported symptoms of affective, somatic, attention-deficit/hyperactivity, and oppositional problems. Future directions and clinical implications are discussed.

Abstract
Controlled trials demonstrate that parenting programs work, but less is known about the processes of change, contextual factors or intervention characteristics that influence trial outcomes. This qualitative study assessed the experiences of Irish parents involved in a randomized controlled trial of the Incredible Years BASIC parenting program, with a view to understanding how and why the program works, or does not work, within disadvantaged settings. Data from 33 parents of young children (aged 3-7 years) with conduct problems were collected by semi-structured interviews and analysed using constructivist grounded theory. Emerging themes indicated that parents perceived the program to have produced positive changes through learning key parenting skills (e.g. positive attention, empathy and problem-solving skills) and through enhanced parental mood/confidence, derived primarily from gaining non-judgmental support from the group. Parents also experienced cultural, personal and environmental challenges in learning the new skills, including discomfort with praise and positive attention, conflict with their partner and parenting within an antisocial environment. Parents dropped out of the course for largely circumstantial reasons. These findings should help to inform the future implementation of this well-known parenting program both in Ireland and elsewhere.

Abstract
BACKGROUND Cognitive-behavioural therapy (CBT) has proven to be effective for anxiety-based school refusal, but it is still unknown how CBT for school refusal works, or through which mechanisms. AIMS Innovative statistical approaches for analyzing small uncontrolled samples were used to investigate the role of self-efficacy in mediating CBT outcomes for anxiety-based school refusal. METHOD Participants were 19 adolescents (12 to 17 years) who completed a manual-based cognitive-behavioural treatment. Primary outcomes (school attendance; school-related fear; anxiety) and secondary outcomes (depression; internalizing problems) were assessed at post-treatment and 2-month follow-up. RESULTS Post-treatment increases in school attendance and decreases in fear about attending school the next day were found to be mediated by self-efficacy. Mediating effects were not observed at 2-month follow-up. CONCLUSIONS These findings provide partial support for the role of self-efficacy in mediating the outcome of CBT for school refusal. They contribute to a small body of literature suggesting that cognitive change enhances CBT outcomes for young people with internalizing problems. Regarding methodology, the product of coefficient test appears to be a valuable way to study mediation in outcome studies involving small samples.

Abstract
Despite guidelines and repeated calls from the literature, statistical mediation analysis in youth treatment outcome research is rare. Even more concerning is that many studies that have reported mediation analyses do not fulfill basic requirements for mediation analysis, providing inconclusive data and clinical implications. As a result, after more than five decades of research, it is still largely unknown through which processes youth treatment works and what the effective treatment components are. In this article, we present ten ways in which the use of statistical mediation analysis in youth treatment outcome research may be improved. These ten ways are related both to conceptual and methodological issues. In discussing how youth clinical researchers may optimally implement these directions, we argue that studies should employ the strongest research designs possible. In so doing, we describe different levels of a mediation evidence ladder. Studies on each step of the ladder contribute to an understanding of mediation processes, but the strongest evidence for mediation is provided by studies that can be classified at the highest level. With the help of the ladder of mediation evidence, results from youth mediation treatment outcome research can be evaluated on their scientific as well as clinical impact.

Abstract
Careful reviews and meta-analyses have made valuable contributions to understanding the efficacy of psychosocial interventions for cancer patients. An important next step is to determine the mediators that explain the influence of efficacious interventions on outcomes. This systematic review summarizes tests of mediating variables from twenty-two projects conducted from 1989-2010. Although all authors provided some type of rationale for considering particular mediating relationships, the investigations varied widely with respect to the extent to which formal theoretical constructs were tested, the type and goals of the interventions studied, and the broad types of outcomes and potential mediators examined. Although there was some evidence supporting selected mediating relationships, with positive findings often found when mediating variables represented behaviors targeted by an intervention, the findings were mixed. Expanding the focus of research to include mechanisms in psychosocial oncology intervention research is necessary for providing a unified picture of how mediating relationships may be operating in this field.
