New Zealand's early response to the novel coronavirus pandemic included a strict lockdown which eliminated community transmission of COVID-19. However, this success was not without cost, both ...economic and social. In our study, we examined the psychological wellbeing of New Zealanders during the COVID-19 lockdown when restrictions reduced social contact, limited recreation opportunities, and resulted in job losses and financial insecurity. We conducted an online panel survey of a demographically representative sample of 2010 adult New Zealanders in April 2020. The survey contained three standardised measures-the Kessler Psychological Distress Scale (K10), the GAD-7, and the Well-Being Index (WHO-5)-as well as questions designed specifically to measure family violence, suicidal ideation, and alcohol consumption. It also included items assessing positive aspects of the lockdown. Thirty percent of respondents reported moderate to severe psychological distress (K10), 16% moderate to high levels of anxiety, and 39% low wellbeing; well above baseline measures. Poorer outcomes were seen among young people and those who had lost jobs or had less work, those with poor health status, and who had past diagnoses of mental illness. Suicidal ideation was reported by 6%, with 2% reporting making plans for suicide and 2% reporting suicide attempts. Suicidality was highest in those aged 18-34. Just under 10% of participants had directly experienced some form of family harm over the lockdown period. However, not all consequences of the lockdown were negative, with 62% reporting 'silver linings', which included enjoying working from home, spending more time with family, and a quieter, less polluted environment. New Zealand's lockdown successfully eliminated COVID-19 from the community, but our results show this achievement brought a significant psychological toll. Although much of the debate about lockdown measures has focused on their economic effects, our findings emphasise the need to pay equal attention to their effects on psychological wellbeing.
Introduction:
People with pre-existing mental health conditions may have been disproportionally impacted by the COVID-19 pandemic and associated public health restrictions. In this study, we compared ...psychological outcomes, experiences and sources of stress over the pandemic lockdown in New Zealanders with and without a previous diagnosis of mental illness.
Methods:
Two online surveys were conducted in New Zealand over the level 4 lockdown in April 2020 measuring psychological distress, anxiety, well-being, suicidality, alcohol use and subjective experiences. They included 3389 participants, of whom 18.4% reported having been previously diagnosed with a mental illness.
Results:
During the lockdown, people previously diagnosed with a mental illness had about twice the risk of reporting moderate-high levels of psychological distress (K10 ⩾ 12), at least moderate levels of anxiety (GAD-7 ⩾ 10) and poor well-being (WHO-5 ⩽ 12). They reported increased alcohol use and were about four times as likely to have experienced suicidal thoughts with 3% reporting having made a suicide attempt over the lockdown period. They reported less satisfaction with, and poorer relationships with people in their ‘bubble’, reduced social contacts and greater loneliness. They also reported higher levels of health and financial concerns.
Conclusion:
During the COVID-19 lockdown in New Zealand, people with a previous diagnosis of a mental illness were at increased risk of detrimental psychological outcomes. This highlights the importance of recognising this and the challenges people face in pandemics.

To report the feasibility of delivering and the effectiveness of brief Group Transdiagnostic Cognitive Behavioural Therapy (TCBT) via Zoom for anxiety and/or depression in primary care.
Participants ...were eligible for this open-label study if their primary care clinician recommended brief psychological intervention for clinically diagnosed anxiety and/or depression. Group TCBT included an individual assessment followed by four x 2-hour manualised therapy sessions. Primary outcome measures assessed recruitment, adherence to treatment and reliable recovery measured using the PHQ-9 and GAD-7.
Twenty-two participants received TCBT over three groups. Recruitment and adherence to TCBT met feasibility thresholds for delivering group TCBT via Zoom. Improvements in the PHQ-9, GAD-7 and reliable recovery were present 3 and 6 months following treatment commencement.
Brief TCBT delivered using Zoom is a feasible treatment for anxiety and depression diagnosed in primary care. Definitive RCTs are required to provide confirmatory evidence of efficacy for brief group TCBT in this setting.
This systematic review aims to identify and evaluate all studies that measured psychological distress or mental disorder following the Canterbury earthquakes to establish the psychological ...consequences of the earthquakes on those exposed. A secondary aim is to outline and emphasise key methodological factors in disaster research.
Eligible studies were identified following a comprehensive literature search. A quality assessment was undertaken for all included studies. This was followed by methodological and descriptive review.
Thirty‐one papers measuring psychological distress or mental disorder following the Canterbury earthquakes were identified. These papers reported outcomes from 20 separate studies of which seven were rated high‐quality, eight were rated medium and five were rated low‐quality. Key methodological findings and outcomes are discussed for each study.
The Canterbury earthquakes were associated with widespread but not universal adverse effects on mental health. Disaster research quality is assisted by representative samples, repeated measures, and the use of appropriate controls to allow accurate assessments of psychological consequences to be made.
The presence of widespread adverse effects as a result of the earthquakes suggests broad‐ranging community initiatives are essential to mitigate the negative consequences of disasters.
The extent to which exposure to childhood sexual and physical abuse increases the risk of psychotic experiences in adulthood is currently unclear.AimsTo examine the relationship between childhood ...sexual and physical abuse and psychotic experiences in adulthood taking into account potential confounding and time-dynamic covariate factors.
Data were from a cohort of 1265 participants studied from birth to 35 years. At ages 18 and 21, cohort members were questioned about childhood sexual and physical abuse. At ages 30 and 35, they were questioned about psychotic experiences (symptoms of abnormal thought and perception). Generalised estimating equation models investigated covariation of the association between abuse exposure and psychotic experiences including potential confounding factors in childhood (socioeconomic disadvantage, adverse family functioning) and time-dynamic covariate factors (mental health, substance use and life stress).
Data were available for 962 participants; 6.3% had been exposed to severe sexual abuse and 6.4% to severe physical abuse in childhood. After adjustment for confounding and time-dynamic covariate factors, those exposed to severe sexual abuse had rates of abnormal thought and abnormal perception symptoms that were 2.25 and 4.08 times higher, respectively than the 'no exposure' group. There were no significant associations between exposure to severe physical abuse and psychotic experiences.
Findings indicate that exposure to severe childhood sexual (but not physical) abuse is independently associated with an increased risk of psychotic experiences in adulthood (particularly symptoms of abnormal perception) and this association could not be fully accounted for by confounding or time-dynamic covariate factors.Declaration of interestNone.

Objective:
Post-traumatic stress disorder involves excessive retrieval of traumatic memories. Glucocorticoids impair declarative memory retrieval. This preliminary study examined the effect of acute ...hydrocortisone administration on brain activation in individuals with earthquake-related post-traumatic stress disorder compared with earthquake-exposed healthy individuals, during retrieval of traumatic memories.
Method:
Participants exposed to earthquakes with (n = 11) and without post-traumatic stress disorder (n = 11) underwent two functional magnetic resonance imaging scans, 1-week apart, in a double-blind, placebo-controlled, counter-balanced design. On one occasion, they received oral hydrocortisone (20 mg), and on the other, placebo, 1 hour before scanning. Symptom provocation involved script-driven imagery (traumatic and neutral scripts) and measures of self-reported anxiety.
Results:
Arterial spin labelling showed that both post-traumatic stress disorder and trauma-exposed controls had significantly reduced cerebral blood flow in response to retrieval of traumatic versus neutral memories in the right hippocampus, parahippocampal gyrus, calcarine sulcus, middle and superior temporal gyrus, posterior cingulate, Heschl’s gyrus, inferior parietal lobule, angular gyrus, middle occipital gyrus, supramarginal gyrus, lingual gyrus and cuneus, and the left prefrontal cortex. Hydrocortisone resulted in non-significant trends of increasing subjective distress and reduced regional cerebral blood flow in the left inferior frontal gyrus, left anterior cingulate gyrus, middle temporal gyrus, cerebellum, postcentral gyrus and right frontal pole, during the trauma script.
Conclusion:
Findings do not fit with some aspects of the accepted neurocircuitry model of post-traumatic stress disorder, i.e., failure of the medial prefrontal cortex to quieten hyperresponsive amygdala activity, and the potential therapeutic benefits of hydrocortisone. They do, however, provide further evidence that exposure to earthquake trauma, regardless of whether post-traumatic stress disorder eventuates, impacts brain activity and highlights the importance of inclusion of trauma-exposed comparisons in studies of post-traumatic stress disorder.
Our previous research has demonstrated significant cognitive effects of earthquake exposure 2-3 years following the Canterbury earthquake sequence of 2011. Such impairment has major implications for ...a population trying to recover, and to rebuild, a devastated city. This study aims to examine psychological, cognitive and biological factors that may contribute to subjective cognitive difficulties in a large group of individuals exposed to the Canterbury earthquake sequence.
Two-hundred earthquake-exposed participants from an existing large cohort study (Christchurch Health and Development Study, CHDS) will be recruited. Inclusion is based on results of online screening of the CHDS cohort, using the Cognitive Failures Questionnaire. Individuals scoring the highest (n=100) and lowest (n=100), representing the highest and lowest levels of subjective cognitive impairment, are selected. Exclusions are: psychotic/bipolar disorders, serious substance/alcohol dependence, chronic medical conditions, pregnancy and previous serious head injury. Participants will undergo a half-day assessment including clinician-rated interviews, self-report measures, objective and subjective cognitive assessments, blood sample collection and physical measurements. The primary analysis will compare cognitive, psychological and biological measures in 'high' and 'low' subjective cognitive impairment groups. The study will have power (p<0.05, α=0.8) to show a difference between groups of 0.4 SD on any variable.
Ethical approval for this study was granted by the New Zealand Health and Disability Ethics Committee. The online screening component of the study received ethical approval on 1 April 2021 (16/STH/188, PAF 7), and the main study (subsequent to screening) received approval on 16 August 2021 (Northern A 21/NTA/68). All participants provide written informed consent. Findings will be disseminated initially to the CHDS cohort members, the wider Canterbury community, and then by publication in scientific journals and conference presentations.
