Item Avian Influenza Virus Surveillance Across New Zealand and Its Subantarctic Islands Detects H1N9 in Migratory Shorebirds, but Not 2.3.4.4b HPAI H5N1(John Wiley and Sons Ltd, 2025-04) Waller SJ; Wierenga JR; Heremia L; Darnley JA; de Vries I; Dubrulle J; Robinson Z; Miller AK; Niebuhr CN; Melville DS; Schuckard R; Battley PF; Wille M; Alai B; Cole R; Cooper J; Ellenberg U; Elliott G; Faulkner J; Fischer JH; Fyfe J; Hay L; Houston D; Keys BC; Long J; Long R; Mattern T; McGovern H; McNutt L; Moore P; Neil O; Osborne J; Pagé A-S; Parker KA; Perry M; Philp B; Reid J; Rexer-Huber K; Russell JC; Sagar R; Ruru TT; Thompson T; Thomson L; Tinnemans J; Uddstrom L; Waipoua TA; Walker K; Whitehead E; Wickes C; Young MJ; McInnes K; Winter D; Geoghegan JLHighly pathogenic avian influenza (HPAI) virus subtype H5N1 has never been detected in New Zealand. The potential impact of this virus on New Zealand's wild birds would be catastrophic. To expand our knowledge of avian influenza viruses across New Zealand, we sampled wild aquatic birds from New Zealand, its outer islands and its subantarctic territories. Metatranscriptomic analysis of 700 individuals spanning 33 species revealed no detection of H5N1 during the annual 2023–2024 migration. A single detection of H1N9 in red knots (Calidris canutus) was noted. This study provides a baseline for expanding avian influenza virus monitoring in New Zealand.Item Acceptance and commitment therapy for mild traumatic brain injury (ACTion-mTBI): a quasiexperimental feasibility study(BMJ Publishing Group Ltd, 2025-02-16) Faulkner J; Prouty D; Devlin L; Appleton D; Roche M; Below K; Moffat J; Snell D; Williams MN; Barker-Collo S; Theadom AOBJECTIVES: 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.Item Physical Activity, Mental Health and Wellbeing during the First COVID-19 Containment in New Zealand: A Cross-Sectional Study(MDPI (Basel, Switzerland), 2021-11) O'Brien WJ; Badenhorst CE; Draper N; Basu A; Elliot CA; Hamlin MJ; Batten J; Lambrick D; Faulkner JStrategies implemented worldwide to contain COVID-19 outbreaks varied in severity across different countries, and established a new normal for work and school life (i.e., from home) for many people, reducing opportunities for physical activity. Positive relationships of physical activity with both mental and physical health are well recognised, and therefore the aim was to ascertain how New Zealand’s lockdown restrictions impacted physical activity, mental health and wellbeing. Participants (n = 4007; mean ± SD: age 46.5 ± 14.7 years, 72% female, 80.7% New Zealand European) completed (10–26 April 2020) an online amalgamated survey (Qualtrics): International Physical Activity Questionnaire: Short Form; Depression, Anxiety and Stress Scale-9; World Health Organisation-Five Well-Being Index; Stages of Change Scale. Positive dose–response relationships between physical activity levels and wellbeing scores were demonstrated for estimates that were unadjusted (moderate activity OR 3.79, CI 2.88–4.92; high activity OR 8.04, CI 6.07–10.7) and adjusted (confounding variables: age, gender, socioeconomic status, time sitting and co-morbidities) (moderate activity 1.57, CI 1.11–2.52; high activity 2.85, CI 1.97–4.14). The study results support previous research demonstrating beneficial effects of regular physical activity on mental health and wellbeing. Governments may use these results to promote meeting physical activity guidelines in order to protect mental health and wellbeing during the ongoing COVID-19 restrictions and future pandemics.Item Physical Activity, Mental Health and Wellbeing of Adults within and during the Easing of COVID-19 Restrictions, in the United Kingdom and New Zealand(MDPI (Basel, Switzerland), 2022-02) Faulkner J; O'Brien WJ; Stuart B; Stoner L; Batten J; Wadsworth D; Askew CD; Badenhorst CE; Byrd E; Draper N; Elliot C; Fryer S; Hamlin MJ; Jakeman JR; Mackintosh KA; McNarry MA; Mitchelmore A; Ryan-Stewart H; Saynor Z; Schaumberg MA; Spiegelhalter E; Stone K; Lambrick DPhysical activity (PA) participation was substantially reduced at the start of the COVID-19 pandemic. The purpose of this study was to assess the association between PA, mental health, and wellbeing during and following the easing of COVID-19 restrictions in the United Kingdom (UK) and New Zealand (NZ). In this study, 3363 adults completed online surveys within 2–6 weeks of initial COVID-19 restrictions (April/May 2020) and once restrictions to human movement had been eased. Outcome measures included the International Physical Activity Questionnaire Short-Form, Depression Anxiety and Stress Scale-9 (mental health) and World Health Organisation-5 Wellbeing Index. There were no differences in PA, mental health or wellbeing between timepoints (p > 0.05). Individuals engaging in moderate or high volume of PA had significantly better mental health (−1.1 and −1.7 units, respectively) and wellbeing (11.4 and 18.6 units, respectively) than individuals who engaged in low PA (p < 0.001). Mental health was better once COVID-19 restrictions were eased (p < 0.001). NZ had better mental health and wellbeing than the UK (p < 0.001). Participation in moderate-to-high volumes of PA was associated with better mental health and wellbeing, both during and following periods of COVID-19 containment, compared to participation in low volumes of PA. Where applicable, during the current or future pandemic(s), moderate-to-high volumes of PA should be encouraged.
