Introduction: A cluster randomised controlled trial, the Meaning, Agency and Nurturing Autonomy (MANA) study, is underway comparing the effects of occupational performance coaching (OPC) and usual care on the social participation, health and well-being of children with neurodisability and their caregivers. This protocol presents the realist process evaluation which is occurring in parallel with the trial to allow testing and further refinement of OPC programme theory, as represented in its logic model. The aim of this realist evaluation is to examine what works, for whom, in the implementation of OPC with caregivers of children with neurodisability (in particular, Māori and Pasifika) in current service delivery contexts.

High-quality evidence on the prevalence and impact of health, wellbeing, and disability among Māori, and other Indigenous peoples, is crucial for mitigating health inequities. Current surveys are predominantly centred within a biomedical paradigm, with the constructs mismatched with Indigenous worldviews. We aimed to develop and deploy an accessible and culturally grounded survey exploring Māori health, wellbeing, and disability using a Kaupapa Māori Research methodology.

Purpose: Few interventions improve outcomes for people with Chronic Obstructive Pulmonary Disease (COPD), particularly higher risk groups such as those admitted to hospital with an acute exacerbation of COPD (AECOPD). The aim of the study was to test the feasibility and acceptability of a modified version of the Take Charge program in people after AECOPD and to determine the potential to improve self-reported limitations, health-related quality of life and reduce future hospitalizations.

Patients And Methods: A prospective, parallel group randomized trial with blinded endpoint assessment.

Occupational Performance Coaching (OPC) is a goal-oriented approach in which client agency takes precedence in goal selection, analysis, choice of action, and evaluation of success. The intended outcomes of OPC are improved occupational performance and participation in clients' life situations. Randomized clinical trials are needed to determine the effectiveness of OPC.

Purpose: Current guidelines for prevention of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) reflect clinical understanding of the causes of exacerbations but with a limited recognition of person-specific contributing factors. As part of a randomized trial of a person-centered intervention aiming to promote self-determination, we describe personal perspectives of those with chronic obstructive pulmonary disease (COPD) on what they saw as the causes and best ways to stay well and prevent rehospitalization after an AECOPD.

Patients And Methods: Twelve participants (mean age 69.

People with lived experience of disability have poorer health and socioeconomic outcomes than people without it. However, within this population, certain social groups are more likely to experience poorer outcomes due to the impacts of multiple intersecting forms of oppression including colonisation, coloniality and racism. This paper describes the multidimensional impacts of inequities for Indigenous tāngata whaikaha Māori (Māori with lived experience of disability).

Introduction: Persistent non-cancer pain affects one in five adults and is more common in Māori-the Indigenous population of New Zealand (NZ), adults over 65 years, and people living in areas of high deprivation. Despite the evidence supporting multidisciplinary pain management programmes (PMPs), access to PMPs is poor due to long waiting lists. Although online-delivered PMPs enhance access, none have been codesigned with patients or compared with group-based, in-person PMPs.

Introduction: A gap exists in the literature regarding dose-response associations of objectively assessed housing quality measures, particularly dampness and mould, with hospitalisation for acute respiratory infection (ARI) among children.

Methods: A prospective, unmatched case-control study was conducted in two paediatric wards and five general practice clinics in Wellington, New Zealand, over winter/spring 2011-2013. Children aged <2 years who were hospitalised for ARI (cases), and either seen in general practice with ARI not requiring admission or for routine immunisation (controls) were included in the study.

Background: Around 10% of young people suffer from chronic health conditions, and their health care needs are different from those of children or adults. Most research about young people's chronic illness focuses on specific conditions, on younger children's experience, and on the perspectives of parents. This study explored the experiences of young people with two very different chronic conditions (asthma and cancer) and their perception of the New Zealand health system's response to their needs.

Background: Chronic Obstructive Pulmonary Disease (COPD) is of increasing importance with about one in four people estimated to be diagnosed with COPD during their lifetime. None of the existing medications for COPD has been shown to have much effect on the long-term decline in lung function and there have been few recent pharmacotherapeutic advances. Identifying preventive interventions that can reduce the frequency and severity of exacerbations could have important public health benefits.
