RESUMO
OBJECTIVE: Interference control is used to overcome conflict among competing memory representations and may contribute to memory difficulties in ADHD. This meta-analytic review examined memory interference to evaluate susceptibility to proactive, retroactive, and memory control interference among those with ADHD. METHOD: Twenty studies (1987-2019) examining verbal memory interference in ADHD met inclusion criteria (age: 8-36 years). Proactive and retroactive interference indices were extracted from list-learning tasks, and memory control indices were extracted from experimental paradigms (e.g., directed-forgetting). RESULTS: Children with ADHD were less affected by proactive interference (g=-0.53, 95% CI [-0.75, -0.31]), whereas no significant differences were found in adults (g=0.13, 95% CI [-0.02, 0.28]). Adults and children with ADHD exhibited more retroactive interference (g=0.17, 95% CI [0.05, 0.29]) and performed worse on memory control tasks (g=0.35, 95% CI [0.08, 0.62]) relative to controls. CONCLUSION: Differences in verbal memory interference control in ADHD were observed but effects were different depending upon interference type and participant age.

Technology-based self-help interventions have the potential to increase access to evidence-based mental healthcare, especially for families affected by natural disasters. However, development of these interventions is a complex process and poses unique challenges. Usability testing, which assesses the ability of individuals to use an application successfully, can have a significant impact on the quality of a self-help intervention. This article describes (a) the development of a novel web-based multi-module self-help intervention for disaster-affected adolescents and their parents and (b) a mixed-methods formal usability study to evaluate user response. A total of 24 adolescents were observed, videotaped, and interviewed as they used the depressed mood component of the self-help intervention. Quantitative results indicated an above-average user experience, and qualitative analysis identified 120 unique usability issues. We discuss the challenges of developing self-help applications, including design considerations and the value of usability testing in technology-based interventions, as well as our plan for widespread dissemination.

OBJECTIVES: Telehealth technology may reduce the effect of treatment barriers and improve participation in treatment for veterans with posttraumatic stress disorder (PTSD). The present study is an ongoing randomized controlled trial comparing the effectiveness of prolonged exposure (PE) delivered via in person or home-based video telehealth modalities. METHOD: A total of 52 veterans with combat-related PTSD were randomized to receive 8-12 weeks of PE through either home-based telehealth or standard in-person office-based care. RESULTS: Participants evinced significant reductions in symptoms of PTSD, depression, and anxiety from pre- to posttreatment across both conditions. Analyses conducted within a noninferiority framework suggested nonsignificant treatment outcome differences in clinician-reported PTSD and self-reported anxiety between the conditions. Results were inconclusive for self-reported PTSD and depression symptoms. Patient satisfaction ratings did not significantly differ between the two groups. CONCLUSIONS: Results suggest that PE can be delivered via home-based telehealth with outcomes and satisfaction ratings comparable to in-person practices for certain symptoms, however additional research is needed. This modality has the potential to address stigma- and geographic-related barriers to treatment, such as travel time and cost.

Although Web-based treatments have significant potential to assess and treat difficult-to-reach populations, such as trauma-exposed adolescents, the extent that such treatments are accessed and used is unclear. The present study evaluated the proportion of adolescents who accessed and completed a Web-based treatment for postdisaster mental health symptoms. Correlates of access and completion were examined. A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context.

OBJECTIVE: Adolescent depression is a major public health concern. Efficacious interventions exist, but are underutilized. Novel approaches to improving access are therefore a top priority. Web-based approaches offer a viable treatment delivery solution; this approach may reach adolescents who might not otherwise receive formal treatment. Behavioral activation (BA) approaches have had success in treatment of depressive symptoms in youth. The purpose of this article is to: (1) describe the development process of a web-based, behavioral activation intervention for adolescents; (2) summarize the preliminary feasibility data; and (3) discuss the benefits and challenges associated with development and evaluation of adolescent self-help resources. METHODS: The current study is part of a larger NIMH funded study focusing on the development and evaluation of Bounce Back Now (BBN), an evidence-informed, web resource for disaster-affected adolescents and their families. This study is specifically on the development of the BA component of the mood module of BBN, which was evaluated more extensively than other components. We present data from a formal usability evaluation conducted with 24 adolescents, and preliminary usage data collected from 2,000 disaster affected adolescents recruited from the tornado-affected coordinates in Alabama and Joplin, MO. RESULTS: Preliminary data supported the feasibility of this approach: qualitative data with the clinic-based sample revealed favorable reactions to the intervention, and preliminary data from the large ongoing randomized controlled trial have indicated moderate levels of access. CONCLUSIONS: Brief, web-based approaches may offer a promising alternative to address access barriers for adolescents with depressed mood.

The gold-standard treatment for OCD is exposure and ritual prevention (ERP), yet despite its well-established efficacy, only a small percentage of OCD patients have access to this treatment. Remote treatments (e.g., videoconferencing) are becoming increasingly popular avenues for treatment delivery and show promise in increasing patient access to evidence-based mental health care. The current pilot study utilized an open trial to examine the feasibility and preliminary efficacy of videoconference-mediated, twice weekly, ERP for adults (n=15) with OCD. Results revealed that ERP was associated with significant improvements in OCD symptoms and large within-group effect sizes. Among the 10 individuals who completed a 3-month follow-up assessment, 30% of participants no longer met DSM-IV-TR criteria for OCD and 80% of participants were rated as very much or much improved on the CGI. This study adds to the growing body of literature suggesting that videoconference-based interventions are viable alternatives to face-to-face treatment.

UNLABELLED: The increased popularity and functionality of mobile devices has a number of implications for the delivery of mental health services. Effective use of mobile applications has the potential to (a) increase access to evidence-based care; (b) better inform consumers of care and more actively engage them in treatment; (c) increase the use of evidence-based practices; and (d) enhance care after formal treatment has concluded. The current paper presents an overview of the many potential uses of mobile applications as a means to facilitate ongoing care at various stages of treatment. Examples of current mobile applications in behavioural treatment and research are described, and the implications of such uses are discussed. Finally, we provide recommendations for methods to include mobile applications into current treatment and outline future directions for evaluation. KEY PRACTITIONER MESSAGE: Mobile devices are becoming increasingly common among the adult population and have tremendous potential to advance clinical care. Mobile applications have the potential to enhance clinical care at stages of treatment-from engaging patients in clinical care to facilitating adherence to practices and in maintaining treatment gains. Research is needed to validate the efficacy and effectiveness of mobile applications in clinical practice. Research on such devices must incorporate assessments of usability and adherence in addition to their incremental benefit to treatment.

BACKGROUND: Despite large-scale dissemination and implementation efforts of evidence-based psychotherapy to veterans from Operation Enduring/Iraqi Freedom (OEF/OIF), little is known regarding the factors that contribute to the successful completion of these treatments in this high-risk population. The present study investigated predictors of treatment completion during a standardized exposure-based psychotherapy for PTSD. METHODS: Ninety-two OEF/OIF combat veterans enrolled in a randomized controlled trial for an eight session exposure-based psychotherapy for PTSD. All participants completed structured clinical interviews and several background and symptom questionnaires. Of the initial 92 participants, 28% of the sample (n = 26) discontinued treatment prior to completion of the trial. RESULTS: Predictors of discontinuation of treatment were assessed with a hierarchical logistic regression. Disability status was positively associated with treatment discontinuation, and postdeployment social support was negatively associated with discontinuation. In contrast to previous findings, other factors, such as age and PTSD symptomatology, were not identified as significant predictors. CONCLUSIONS: The present study suggested that disability status at the start of treatment increases the risk for treatment discontinuation whereas increased social support buffers against discontinuation. Together, these findings highlight the importance of increased assessment and early intervention when these factors are present to potentially reduce treatment discontinuation and improve treatment outcomes in OEF/OIF veterans with PTSD.

Most individuals with social anxiety disorder (SAD) do not receive any type of treatment. Reasons include logistical barriers (e.g., geographic location, travel time), fear of stigmatization, and fear of the social interactions associated with seeking treatment. Videoconferencing technology holds great promise in the widespread delivery of evidence-based treatments to those who would otherwise not receive treatment. This pilot study assessed the feasibility, acceptability, and initial efficacy of an acceptance-based behavioral intervention using Skype videoconferencing to treat adults with generalized SAD. Twenty-four participants received 12 sessions of weekly therapy and were assessed at pre-treatment, mid-treatment, post-treatment, and 3-month follow-up. Participants and therapists rated the intervention as acceptable and feasible. Analyses revealed significant pre-treatment to follow-up improvements in social anxiety, depression, disability, quality of life, and experiential avoidance, with effect sizes comparable to or larger than previously published results of studies delivering in-person CBT for SAD. Implications and future directions are discussed.

Over 80% of people with social anxiety disorder (SAD) do not receive any type of treatment, despite the existence of effective evidence-based treatments. Barriers to treatment include lack of trained therapists (particularly in nonmetropolitan areas), logistical difficulties (e.g., cost, time, transportation), concerns regarding social stigma, and fear of negative evaluation from health care providers. Interventions conducted through electronic communication media, such as the Internet, have the potential to reach individuals who otherwise would not have access to evidence-based treatments. Second Life is an online virtual world that holds great promise in the widespread delivery of evidence-based treatments. We assessed the feasibility, acceptability, and initial efficacy of an acceptance-based behavior therapy in Second Life to treat adults with generalized SAD. Participants (n=14) received 12 sessions of weekly therapy and were assessed at pretreatment, midtreatment, posttreatment, and follow-up. Participants and therapists rated the treatment program as acceptable and feasible, despite frequently encountered technical difficulties. Analyses showed significant pretreatment to follow-up improvements in social anxiety symptoms, depression, disability, and quality of life, with effect sizes comparable to previously published results of studies delivering in-person cognitive behavior therapy for SAD. Implications and future directions are discussed.

The present study represents one of the first comparisons of the long-term effectiveness of traditional cognitive behavior therapy (i.e., Beckian cognitive therapy; CT) and acceptance and commitment therapy (ACT). One hundred thirty-two anxious or depressed outpatients were randomly assigned to receive either CT or ACT, and were assessed at posttreatment (n=90) and at 1.5-year (n=91) follow-up. As previously reported, the two treatments were equivalently effective at posttreatment according to measures of depression, anxiety, overall (social/occupational/symptom-related) functioning, and quality of life. However, current results suggest that treatment gains were better maintained at follow-up in the CT condition. Clinical significance analyses revealed that, at follow-up, one-third more CT patients were in the clinically normative range in terms of depressive symptoms and more than twice as many CT patients were in the normative range in terms of functioning levels. The possible long-term advantage of CT relative to ACT in this population is discussed.

Effectiveness of exposure therapy for posttraumatic stress disorder (PTSD) may be adversely influenced by comorbid disorders. The present study investigated behavioral activation and therapeutic exposure (BA-TE), a new integrated treatment designed specifically for comorbid symptoms of PTSD and depression. Combat veterans with PTSD (N = 117) completed eight sessions of BA-TE that included two phases of treatment: (a) behavioral activation (BA) in which some activities involved situational exposures and (b) BA and situational exposures with imaginal exposures. Findings supported improvements in symptoms of PTSD, and overlapping symptoms of PTSD and depression, but not in nonoverlapping symptoms of depression. The findings also demonstrated a relatively consistent rate of change in PTSD and depression symptoms during BA-TE, despite the addition of imaginal exposures midway through the treatment. Together, these findings provide preliminary support for BA-TE as a treatment for PTSD and depression, and highlight the utility of transdiagnostic treatments in addressing comorbidity and symptom overlap.

Debate continues about the extent to which postulated mechanisms of action of cognitive behavior therapies (CBT), including standard CBT (i.e., Beckian cognitive therapy [CT]) and acceptance and commitment therapy (ACT) are supported by mediational analyses. Moreover, the distinctiveness of CT and ACT has been called into question. One contributor to ongoing uncertainty in this arena is the lack of time-varying process data. In this study, 174 patients presenting to a university clinic with anxiety or depression who had been randomly assigned to receive either ACT or CT completed an assessment of theorized mediators and outcomes before each session. Hierarchical linear modeling of session-by-session data revealed that increased utilization of cognitive and affective change strategies relative to utilization of psychological acceptance strategies mediated outcome for CT, whereas for ACT the mediation effect was in the opposite direction. Decreases in self-reported dysfunctional thinking, cognitive "defusion" (the ability to see one's thoughts as mental events rather than necessarily as representations of reality), and willingness to engage in behavioral activity despite unpleasant thoughts or emotions were equivalent mediators across treatments. These results have potential implications for the theoretical arguments behind, and distinctiveness of, CT and ACT.

Many university students suffer from test anxiety that is severe enough to impair performance. Given mixed efficacy results of previous cognitive-behavior therapy (CBT) trials and a theoretically driven rationale, an acceptance-based behavior therapy (ABBT) approach was compared to traditional CBT (i.e., Beckian cognitive therapy; CT) for the treatment of test anxiety. In this pilot study, 16 university students with test anxiety were randomly assigned to receive either a CT or ABBT 2-hr group workshop. The two treatments produced markedly different effects on test performance (measured by exam scores), with those receiving ABBT experiencing improvements in performance, whereas those receiving CT exhibited reduced performance. In addition, there was a suggestion that ABBT might have been more effective at reducing subjectively experienced test anxiety (i.e., a nonsignificant but medium-sized group by time interaction effect). Implications of these results for the treatment of test anxiety and for theoretical notions related to cognitive change strategies are discussed.
