    OBJECTIVES: This study aimed to determine the feasibility of recruiting, implementing and delivering an acceptance and commitment therapy (ACT) intervention for mild traumatic brain injury (mTBI) (ACTion-mTBI) within a multidisciplinary outpatient mTBI rehabilitation services. The study also aimed to conduct a preliminary investigation of group differences between ACTion-mTBI and an equivalent cognitive behavioural therapy (CBT) intervention on various outcome measures and psychological treatment targets. DESIGN: A two-arm quasiexperimental feasibility study. SETTING: Five mTBI rehabilitation clinics throughout New Zealand. INTERVENTION: Psychologists working in mTBI rehabilitation clinics throughout New Zealand were trained to deliver ACTion-mTBI or CBT. Eligible participants were assigned to either of these interventions based on the psychologist available at the clinic they were referred to. ACTion-mTBI is a five sessions intervention that incorporates all six components of the ACT model. The CBT intervention is an equivalent intervention and incorporating all four components of the CBT model. Both interventions are adapted for an mTBI context. PRIMARY OUTCOME MEASURES: The primary outcomes were related to the feasibility of ACTion-mTBI. This included recruitment, retention and treatment adherence of participants, study procedure and fidelity of treatment delivery. SECONDARY OUTCOME MEASURES: To explore group differences between ACTion-mTBI and CBT on functional disability, postconcussion symptoms, mental health, valued living and psychological flexibility. RESULTS: The intervention proved feasible to implement with community-based mTBI rehabilitation services. Attrition rates were comparable between the two psychological interventions and fidelity to the treatments was high. At post-treatment, when covarying pretreatment scores, ACTion-mTBI had a significantly greater improvement in functional disability than CBT (moderate effect). ACTion-mTBI also had a significantly greater reduction in postconcussion symptoms, anxiety and stress. Promisingly, significant improvements in psychological flexibility was also found post-treatment. There were no group differences on depressive symptoms and valued living. CONCLUSION: We conclude that a full clinical trial of ACTion-mTBI for individuals with mTBI is feasible and warranted. TRIAL REGISTRATION NUMBER: ACTRN1262100059482.

    Telehealth-delivered naturalistic developmental behavioural intervention with and without caregiver acceptance and commitment therapy for autistic children and their caregivers: protocol for a multi-arm parallel group randomised clinical trial.
    (BMJ Publishing Group Limited, 2023-05-30) McLay L; Emerson LM; Waddington H; van Deurs J; Hunter J; Blampied N; Hapuku A; Macfarlane S; Bowden N; van Noorden L; Rispoli M
    INTRODUCTION: Timely access to early support that optimises autistic children's development and their caregiver's mental health is critical. Naturalistic developmental behavioural interventions (NDBIs) and acceptance and commitment therapy (ACT) are evidence-based supports that can enhance child learning and behaviour, and adult well-being, respectively. The traditional face-to-face delivery of these approaches is resource intensive. Further, little is known about the benefit of parallel child-focused and caregiver-focused supports. The aims of this trial are to evaluate the effectiveness and social validity of telehealth-delivered, caregiver-implemented, child-focused NDBI and caregiver-focused ACT when delivered alone and in parallel, on autistic children's social communication and caregiver well-being. METHODS AND ANALYSIS: The study will use a randomised, single-blind clinical trial with three parallel arms: NDBI; ACT and ACT+NDBI. We will recruit a minimum of 78, 2-5-year-old autistic children and their families throughout Aotearoa New Zealand. Support will be delivered over 13 weeks using a combination of culturally enhanced web-based modules and online group coaching. Primary outcome variables include children's social communication/engagement with their caregiver as well as caregiver stress and will be evaluated using a repeated measures multivariate analysis of variance. Outcome variables are assessed at baseline (before randomisation), immediately postparticipation and at 3-month follow-up. ETHICS AND DISSEMINATION: The trial is approved by the Health and Disability Ethics Committee (2022 FULL 12058). The findings of this trial will be disseminated through peer-reviewed journals and national and international conference proceedings regardless of the magnitude/direction of effect. Additionally, data will be shared with stakeholder groups, service providers and health professionals. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12622001134718).
