Emotion regulation therapy (ERT) for generalized anxiety disorder (GAD) and accompanying major depressive disorder (MDD) is a theoretically derived, evidence-based treatment that integrates principles from traditional and contemporary cognitive-behavioral and experiential approaches with basic and translational findings from affect science to offer a blueprint for improving intervention by focusing on the motivational responses and corresponding self-referential regulatory characteristics. Preliminary evidence supports the efficacy of a 20-session version of ERT. However, previous trials of ERT and other traditional and contemporary cognitive-behavioral therapies have often utilized relatively homogeneous samples. Various contextual and demographic factors may be associated with challenges that increase risk for negative mental and social outcomes for young adults ages 18–29, particularly for individuals from diverse backgrounds. The aim of this pilot study was to examine the effectiveness of a briefer 16-session version of ERT in a racially and ethnically diverse sample of young adults. Participants (N = 31) were enrolled at an urban-based, commuter college who consented to treatment for anxiety, worry, or depression at an on-campus counseling center. Open-trial results demonstrate strong ameliorative changes in worry, rumination, self-reported and clinician-rated GAD and MDD severity, social disability, quality of life, attentional flexibility, decentering/distancing, reappraisal, trait mindfulness, and negative emotionality from pre- to posttreatment. These gains were maintained throughout a 3- and 9-month follow-up. These findings provide preliminary evidence for the efficacy of ERT in treating a racially and ethnically heterogeneous population. Further, this study highlights comparable effectiveness of a briefer 16-session version of ERT. 相似文献

Discrete‐trial teaching is an effective teaching procedure that must be implemented with high integrity to produce optimal learning. Behavioral Skills Training (BST) has proven effective for staff training; however, BST is time and labor intensive. Computer‐based instruction (CBI) programs may provide a more efficient and cost‐effective alternative to live training if the CBI program is as effective as BST in producing accurate implementation. The current study compared CBI to BST to train novice undergraduate students to conduct discrete‐trial teaching. Participants were randomly assigned to one of the two conditions and assessed prior to and after the completion of training. Results indicated that although both BST and CBI were effective at training participants to implement discrete‐trial teaching, BST was slightly but significantly more effective whereas CBI quickly created a return on the investment of product development. 相似文献

The Mental Health First Aid First Nations course was adapted from Mental Health First Aid Basic to create a community‐based, culturally safe and relevant approach to promoting mental health literacy in First Nations contexts. Over 2.5 days, the course aims to build community capacity by teaching individuals to recognize and respond to mental health crises. This feasibility trial utilized mixed methods to evaluate the acceptability, cultural adaptation, and preliminary effectiveness of MHFAFN. Our approach was grounded in community‐based participatory research principles, emphasizing relationship‐driven procedures to collecting data and choice for how participants shared their voices. Data included participant interviews (n = 89), and surveys (n = 91) from 10 groups in four provinces. Surveys contained open‐ended questions, retrospective pre‐post ratings, and a scenario. We utilized data from nine facilitator interviews and 24 facilitator implementation surveys. The different lines of evidence converged to highlight strong acceptability, mixed reactions to the cultural adaptation, and gains in participants’ knowledge, mental health first aid skill application, awareness, and self‐efficacy, and reductions in stigma beliefs. Beyond promoting individual gains, the course served as a community‐wide prevention approach by situating mental health in a colonial context and highlighting local resources and cultural strengths for promoting mental well‐being. 相似文献

ObjectiveThis study is the first controlled trial of comprehensive behavioral (ComB) treatment of trichotillomania (TTM). ComB provides individualized treatment based on factors triggering and maintaining hair pulling. Method: Participants (N = 36) were adults (M = 34.08 years old, SD = 12.26) meeting DSM5 criteria for TTM. A majority were female (80%) and Caucasian (75%), whereas 17% were African American and 19% Hispanic/Latinx. In a parallel-group design, participants were randomly assigned to (a) Immediate ComB (12 sessions) or (b) Minimal Attention Control (MAC), followed by delayed ComB after week 12. Follow-up continued through week 38. Primary outcomes were self-report (Massachusetts General Hospital Hair pulling Scale; MGH-HPS) and interviewer-rated (NIMH-Trichotillomania Impact Scale and Trichotillomania Severity Scale; TIS/TSS) TTM symptom severity, as well as diagnosis (Trichotillomania Diagnostic Interview).ResultsImmediate efficacy of ComB (vs. MAC) was statistically significant (p = .03) for self-reported symptoms, with an effect size d = −.78, but not significant for interviewer-rated symptoms or diagnostic status. Immediate ComB was significantly more likely than MAC (27% vs. 0%) to lead to complete abstinence from hair pulling at week 12. Follow-ups showed good maintenance of effects.ConclusionsEfficacy of ComB was established for self-reported symptoms. Future research is needed to establish whether the lack of more widespread effects stems from limitations of the model or to a need for more extensive therapist training, as secondary analyses suggested stronger results among therapists with more TTM experience. 相似文献

Background/Objective Brief transdiagnostic psychotherapies are a possible treatment for emotional disorders. We aimed to determine their efficacy on mild/moderate emotional disorders compared with treatment as usual (TAU) based on pharmacological interventions. Method: This study was a single-blinded randomized controlled trial with parallel design of three groups. Patients (N = 102) were assigned to brief individual psychotherapy (n = 34), brief group psychotherapy (n = 34) or TAU (n = 34). Participants were assessed before and after the interventions with the following measures: PHQ-15, PHQ-9, PHQ-PD, GAD-7, STAI, BDI-II, BSI-18, and SCID. We conducted per protocol and intention-to-treat analyses. Results: Brief psychotherapies were more effective than TAU for the reduction of emotional disorders symptoms and diagnoses with moderate/high effect sizes. TAU was only effective in reducing depressive symptoms. Conclusions: Brief transdiagnostic psychotherapies might be the treatment of choice for mild/moderate emotional disorders and they seem suitable to be implemented within health care systems. 相似文献

People tend to underestimate subtraction and overestimate addition outcomes and to associate subtraction with the left side and addition with the right side. These two phenomena are collectively labeled 'operational momentum' (OM) and thought to have their origins in the same mechanism of 'moving attention along the mental number line'. OM in arithmetic has never been tested in children at the preschool age, which is critical for numerical development. In this study, 3–5 years old were tested with non‐symbolic addition and subtraction tasks. Their level of understanding of counting principles (CP) was assessed using the give‐a‐number task. When the second operand's cardinality was 5 or 6 (Experiment 1), the child's reaction time was shorter in addition/subtraction tasks after cuing attention appropriately to the right/left. Adding/subtracting one element (Experiment 2) revealed a more complex developmental pattern. Before acquiring CP, the children showed generalized overestimation bias. Underestimation in addition and overestimation in subtraction emerged only after mastering CP. No clear spatial‐directional OM pattern was found, however, the response time to rightward/leftward cues in addition/subtraction again depended on stage of mastering CP. Although the results support the hypothesis about engagement of spatial attention in early numerical processing, they point to at least partial independence of the spatial‐directional and magnitude OM. This undermines the canonical version of the number line‐based hypothesis. Mapping numerical magnitudes to space may be a complex process that undergoes reorganization during the period of acquisition of symbolic representations of numbers. Some hypotheses concerning the role of spatial‐numerical associations in numerical development are proposed. 相似文献
