IntroductionChild maltreatment and other traumatic events can have serious long-term physical, social and emotional effects, including a cluster of distress symptoms recognised as ‘complex trauma’. Aboriginal and Torres Strait Islander (Aboriginal) people are also affected by legacies of historical trauma and loss. Trauma responses may be triggered during the transition to parenting in the perinatal period. Conversely, becoming a parent offers a unique life-course opportunity for healing and prevention of intergenerational transmission of trauma. This paper outlines a conceptual framework and protocol for an Aboriginal-led, community-based participatory action research (action research) project which aims to co-design safe, acceptable and feasible perinatalawareness, recognition, assessmentandsupportstrategies for Aboriginal parents experiencing complex trauma.Methods and analysisThis formative research project is being conducted in three Australian jurisdictions (Northern Territory, South Australia and Victoria) with key stakeholders from all national jurisdictions. Four action research cycles incorporate mixed methods research activities including evidence reviews, parent and service provider discussion groups, development and psychometric evaluation of a recognition and assessment process and drafting proposals for pilot, implementation and evaluation. Reflection and planning stages of four action research cycles will be undertaken in four key stakeholder workshops aligned with the first four Intervention Mapping steps to prepare programme plans.Ethics and disseminationEthics and dissemination protocols are consistent with the National Health and Medical Research Council Indigenous Research Excellence criteria of engagement, benefit, transferability and capacity-building. A conceptual framework has been developed to promote the application of core values of safety, trustworthiness, empowerment, collaboration, culture, holism, compassion and reciprocity. These include related principles and accompanying reflective questions to guide research decisions.

In May 2020, an independent working party was convened to determine the mental health and well-being needs of Aboriginal and Torres Strait Islander peoples in Australia, in response to COVID-19. Thirty Aboriginal and Torres Strait Islander leaders and allies worked together in a two-month virtual collaboration process. Here, we provide the working party's five key recommendations and highlight the evidence supporting these proposals. Aboriginal and Torres Strait Islander self-determination and governance must be prioritised to manage the COVID-19 recovery in Aboriginal and Torres Strait Islander communities.

The majority of stakeholders supported the importance of assessing each of the proposed complex trauma domains with Aboriginal parents. However, strong concerns were expressed regarding where, by whom and how this should occur. There was greater emphasis and consistency regarding 'qualities' (e.g., caring), rather than specific 'attributes' (e.g., clinician). Six critical overarching themes emerged: ensuring emotional and cultural safety; establishing relationships and trust; having capacity to respond appropriately and access support; incorporating less direct cultural communication methods (e.g., yarning, dadirri); using strengths-based approaches and offering choices to empower parents; and showing respect, caring and compassion. Conclusion: Assessments to identify Aboriginal parents experiencing complex trauma should only be considered when the prerequisites of safety, trusting relationships, respect, compassion, adequate care, and capacity to respond are assured. Offering choices and cultural and strengths-based approaches are also critical. Without this assurance, there are serious concerns that harms may outweigh any benefits for Aboriginal parents.

Objective: To develop guidelines for the culturally responsive psychosocial assessment of Aboriginal and Torres Strait Islander people presenting to hospital with self-harm and suicidal thoughts. Method: The Delphi method was used to establish expert consensus. A systematic search and review of relevant research literature, existing guidelines and grey literature was undertaken to develop a 286-item questionnaire. The questionnaire contained best practice statements to guide clinicians undertaking psychosocial assessment of Aboriginal and Torres Strait Islander people presenting to hospital with self-harm and suicidal thoughts. An expert panel comprising 28 individuals with clinical, community-based and lived experience in Aboriginal and Torres Strait Islander mental health and/or suicide prevention were recruited and independently rated the items over three rounds. Statements endorsed as essential or important by 90% or more of the expert panel were then synthesised into recommendations for the best practice guideline document. Results: A total of 226 statements across all relevant areas of clinical practice were endorsed. No statements covering the use of structured assessment tools were endorsed. The endorsed statements informed the development of a set of underlying principles of culturally competent practice and recommendations for processes of effective and appropriate engagement; risks, needs and strengths to be assessed; formulation of psychosocial assessment; and recommendations specific to children and young people. Conclusion: The guidelines are based on recommendations endorsed across a range of expertise to address an important gap in the evidence-base for clinically effective and culturally responsive assessment of self-harm and suicidal thoughts by Aboriginal and Torres Strait Islander people in hospital settings. Further work is needed to develop an implementation strategy and evaluate the recommendations in practice.
