Background: Low-intensity interventions targeting a range of mental health issues offer a scalable approach for young trauma survivors in low-middle income countries.

Aims: Here, we present results from a proof-of-concept, randomized, waitlist-controlled trial evaluating MemFlex, an autobiographical memory-based intervention, for trauma-exposed Afghan youth residing in Iran. MemFlex seeks to reduce the negative and overgeneral memory biases which maintain and predict poor mental health.

Materials and methods: Young people aged 12-18 years (N = 40) with parents who had experienced forced migration from Afghanistan were recruited from high schools in Karaj City in Iran. All had experienced a traumatic event in the last year. Participants were randomized to receive four weeks of a group-based delivery of MemFlex or Waitlist. Our primary cognitive outcome was autobiographical memory flexibility, that is, the ability to deliberately retrieve any memory type on demand. Primary clinical outcome was emotional distress, measured on the Farsi version of the Hopkins Symptom Checklist.

Results: Results indicated that MemFlex participants demonstrated large effect sizes for pre-to-post improvement in memory flexibility (d = 2.04) and emotional distress (d = 1.23). These improvements were significantly larger than Waitlist (ds < .49), and were maintained at three-month follow-up.

Discussion: Positive benefits were observed for completion of MemFlex, and future comparison against an active intervention appears warranted.

Conclusion: Further evaluation of MemFlex in this context may offer a low-cost, and low-resource intervention to improve access to psychological intervention for young migrants in low-middle income countries.

Objective: Engaging individuals with co-occurring posttraumatic stress disorder (PTSD) and alcohol misuse (AM) in effective treatments is difficult. Brief, self-directed approaches that deliver empirically supported intervention techniques, such as cognitive-behavioural therapy (CBT) strategies, via technology may be effective and easier-to-access alternatives to traditional in-person therapy approaches for PTSD + AM. This paper describes the protocol for an intervention development study (NCT05372042) that evaluates a text-message intervention combining CBT texts with techniques from cognitive psychology (message framing) and social psychology (growth mindsets) for treatment of PTSD + AM.

Method: The study uses a 3 (message framing: gain vs. loss vs. no framing) × 2 (mindset: growth mindsets vs. not) factorial design to test enhancements to CBT texts. Individuals age 18+, who report symptoms of PTSD and AM, will be recruited to participate. Participants will complete screening, verification, and baseline measures. They will be randomized to condition and receive 3 text messages per week for 4 weeks. Participants will be assessed at post-, 1-, and 3-month follow-up.

Results: Analyses will evaluate whether framing and growth mindsets enhance the efficacy of CBT texts. A priori decision rules will be applied to select the intervention condition that is both the most effective and the simplest, which will be tested in a follow-up randomized controlled trial.

Conclusions: This study will identify the simplest, most efficacious CBT intervention for PTSD + AM. Its use of cognitive and social psychology-based enhancement and of a factorial decision can serve as examples of how to enhance and increase engagement in brief, self-directed CBT interventions.

Objectives: Rates of PTSD are up to 12 times higher in care-experienced young people (CEYP) compared to their peers. Trauma-focused CBTs (tf-CBT) are the best-evidenced treatment for youth with PTSD, yet, in practice, CEYP often struggle to access this treatment. We worked alongside services to understand barriers and facilitators of the implementation of cognitive therapy for PTSD (a type of tf-CBT) to CEYP.

Design: This was an active, open implementation trial.

Methods: We recruited 28 mental health teams across England, including general CAMHS, targeted CAMHS for CEYP and social care-based teams. From these teams, participants were 243 mental health professionals, from a wide variety of professional backgrounds. Following recruitment/intervention training, teams participated in rolling three monthly focus groups and individual interviews, to understand what helped and hindered implementation. Data were analysed using a framework analysis conducted using CFIR 2.0.

Results: Almost half of the teams were able to implement, but only approximately one quarter with CEYP, specifically. Universal barriers that were discussed by almost all teams particularly highlighted service structures and poor resourcing as major barriers to delivery to CEYP, as well as the complexities of the young person and their network. Unique factors that differentiated teams who did and did not implement included commissioning practices, the culture of the team, leadership engagement and style, and the development of supervision structures.

Conclusions: Findings offer key considerations for mental health teams, service leads, commissioners and policy-makers to enhance delivery of best-evidenced mental health treatments like CT-PTSD, for CEYP.

Objectives: Trauma-related conditions, such as post-traumatic stress disorder, are associated with high rates of impairment and distress. Evidence-based interventions for many trauma-related conditions exert robust effects on their primary outcomes. However, logistical, financial, geographic and stigma-related barriers to accessing these interventions exist.

Methods: Innovations that overcome barriers to access and engagement and increase the scalability of interventions for trauma-related conditions are sorely needed.

Results and conclusions: Here, we explore the following two potential avenues towards meeting this need: changes to the delivery model, including embedding interventions in settings which are already accessed by trauma-exposed individuals (e.g. schools, social care systems) and harnessing advancements in technology to provide truly accessible trauma-focussed interventions.

Objective: Young people in care (i.e., in the child welfare system) are a group who have often experienced very high rates of potentially traumatic events, including maltreatment. It is well-documented that they have high rates of trauma-related mental health difficulties, such as posttraumatic stress. To address the needs of the large number of young people who may benefit from support, scalable interventions are crucial. But also important is that they are effective and deliverable - particularly given the complexity of this group and services. We assessed a five-session group CBT-based intervention for PTSD. The primary goal was to understand core procedural and protocol uncertainties to address prior to a definitive trial.

Methods: Participants were 34 10-17 year olds in care, with moderate to severe posttraumatic stress symptoms, and their caregiver. We ran seven groups (four online), delivered in social care and NHS-based mental health teams. Data were collected via pre-, post-, 3-month follow-up questionnaires and qualitative interviews.

Results: Of the 34 participants allocated to the intervention, 27 (80%) attended at least three of the five sessions (most attended all). Caregiver attendance was lower (50%). There was generally good completion of assessment measures. Qualitatively, most participants were positive about the intervention, and many reported improvements in areas such as coping, sleep, and willingness to talk about experiences. However, there were important concerns about the lack of ongoing support, given this was a low-intensity intervention for a group who often had complex needs.

Conclusion: The intervention and research protocols were acceptable to most young people and carers. With modifications, a future definitive trial would likely be possible. However, key considerations include: how (and whether) to screen for PTSD; the trial design; and the option to embed high-intensity support (e.g., via assessing a stepped-care model).

Objectives: Following disaster exposure, a significant proportion of children/adolescents will develop levels of post-traumatic stress symptoms (PTSS) that do not meet diagnostic threshold for PTSD, but which cause ongoing distress. This paper describes the development and pilot testing of a brief, scalable, psychosocial intervention. SOLAR-Kids/Teens has been designed to be delivered by non-mental health professionals ('coaches') to children/adolescents experiencing moderate levels of PTSS following disasters.

Methods: An international collaboration of experts developed The Skills fOr Life Adjustment and Resilience (SOLAR) for Kids and Teens programs. The programs were piloted-using a pre-post mixed methods design-with 10 children and adolescents (8-18 years), with the aims of examining the feasibility of the program's delivery model as well as the program's potential usefulness.

Results: The pilot data indicated that after 1 day of training and with ongoing supervision, the SOLAR program was safe and feasible for coaches to deliver to children/adolescents experiencing PTSS. Coaches reported increased knowledge (p = .001), confidence (p = .001) and skills (p = .006). The programs were acceptable to coaches, children/adolescents and parents. Parents and children/adolescents reported reductions in trauma and anxiety symptoms from pre- to post-treatment, with moderate to large effect sizes.

Conclusions: The preliminary findings demonstrate that the SOLAR-Kids/Teens program is feasible, acceptable and safe to be delivered by trained non-mental health professionals to children and adolescents experiencing PTSS and anxiety following disaster exposure. Randomized controlled trials are required to evaluate the efficacy of the SOLAR-Kids/Teens programs.

Background: Post-traumatic stress disorder (PTSD) poses a global public health challenge. Evidence-based psychotherapies (EBPs) for PTSD reduce symptoms and improve functioning (Forbes et al., Guilford Press, 2020, 3). However, a number of barriers to access and engagement with these interventions prevail. As a result, the use of EBPs in community settings remains disappointingly low (Charney et al., Psychological Trauma: Theory, Research, Practice, and Policy, 11, 2019, 793; Richards et al., Community Mental Health Journal, 53, 2017, 215), and not all patients who receive an EBP for PTSD benefit optimally (Asmundson et al., Cognitive Behaviour Therapy, 48, 2019, 1). Advancements in artificial intelligence (AI) have introduced new possibilities for increasinfg access to and quality of mental health interventions.

Aims: The present paper reviews key barriers to accessing and engaging in EBPs for PTSD, discusses current applications of AI in PTSD treatment and provides recommendations for future AI integrations aimed at reducing barriers to access and engagement.

Discussion: We propose that AI may be utilized to (1) assess treatment fidelity; (2) elucidate novel predictors of treatment dropout and outcomes; and (3) facilitate patient engagement with the tasks of therapy, including therapy practice. Potential avenues for technological advancements are also considered.

Objectives: While 5%-10% of children exposed to natural disasters develop PTSD, few children access support. This paper reports on the proactive 'screen-and-treat' approach deployed following devastating floods in Queensland, Australia, in 2011 and presents results for children in the Lockyer Valley (the most impacted community).

Design: Open treatment study (2011-2012) within a government-funded post-disaster service response.

Methods: One hundred and fifty children (7-12 years) completed pencil-and-paper screening (PTSD, anxiety and depression) at school. Eighty children endorsing either clinical levels of PTSD, or moderate levels of PTSD and clinical levels of either anxiety or depression, and their parents, completed a structured diagnostic interview. Forty-eight children were offered a free trauma-focused CBT intervention. The parents of 19 children accepted this offer. Most clinicians were clinical psychology trainees from local universities. All measures were repeated at post-treatment, 6- and 12-month follow-up. Note: The term 'parents' is used to refer to the wide variety of people serving as a child's primary caregiver.

Results: Pre-treatment, all children met diagnostic criteria for full (N = 17) or sub-clinical PTSD. By post-treatment, 10.5% met criteria for PTSD, with 0% meeting criteria at the 12-month follow-up. The incidence of anxiety and depressive disorders also reduced significantly. There were no differences in outcomes for children seen by trainees compared to experienced clinicians.

Conclusions: A school-based screen-and-treat approach offers potential as a means of identifying and treating children following natural disaster exposure. However, engagement of families at the outset, and when offering intervention was challenging. Postgraduate trainees represent an effective potential workforce in a post-disaster environment.

Objectives: The Emotional Cascade Model posits that rumination is associated with impulsivity and risky behaviours such as substance use. Although trauma-exposed individuals often engage in rumination and problematic cannabis use, this model has not been tested on trauma-exposed cannabis users. Therefore, our study examines the direct and indirect effects between rumination and its subtypes with problematic cannabis use among trauma-exposed cannabis users. We also examine how these associations occur through impulsivity.

Methods: A cross-sectional sample of 56 trauma-exposed young adult cannabis users (M_age = 21 years, 59% female, 73% white) self-reported rumination, impulsivity, and cannabis-related problems. All participants provided written informed consent, and procedures were approved by the university's Institutional Review Board and pre-registered.

Results: Regression analyses indicated total and brooding rumination were related to greater cannabis-related problems, after covarying for number of traumas and cannabis use frequency. Rumination, specifically brooding, was incrementally associated with greater cannabis-related problems and had an indirect effect on cannabis-related problems through impulsivity. Consistent with hypothesis, rumination and impulsivity were incrementally associated with greater problematic cannabis use among trauma-exposed cannabis users.

Conclusion: The current study expands work on the Emotional Cascade Model by supporting the indirect effect of impulsivity in the association between rumination and problematic cannabis use.

Objectives: Despite evidence supporting sleep's role in the development and maintenance of depression, mechanisms underlying this association in young people are less established. Negative interpretation bias (the tendency to interpret ambiguous situations negatively) and repetitive negative thinking (RNT) are important candidate mechanisms. Whilst negative interpretation bias is implicated in depression development, it is a transdiagnostic process and may result from insomnia. Yet, research relating to these constructs is lacking. RNT is another transdiagnostic process implicated in association between negative interpretation bias, depression and insomnia. However, an elaborated model that includes both mechanisms is yet to be tested. It was hypothesised that negative interpretation bias and RNT would sequentially mediate the relationship between sleep/insomnia and depressive symptoms in young people.

Design: The associations predicted by this hypothesis were tested via cross-sectional mediation in a sample of 214 participants (M_age = 19.19 years, SD = 1.67, Range_age = 17-24 years, 20% male).

Methods: Participants completed questionnaire measures of insomnia symptoms, depression symptoms and RNT, an ambiguous scenarios task and a 1-week sleep diary.

Results: Results were consistent with negative interpretation bias and RNT as sequential mechanisms which partially account for the relationship between sleep (i.e., insomnia severity and sleep parameters) and depression.

Conclusions: This study supports negative interpretation bias and RNT as mechanisms linking insomnia and depression in young people, as the predicted associations between these variables were observed. Future research should investigate the causal/directional associations. However, results support theoretical models, and suggest sleep, interpretation bias and RNT may be important processes to target in preventing and treating depression.
