ItemNo Preview AvailablePsychological-health correlates of physical activity and sedentary behaviour during the COVID pandemic(ELSEVIER SCI LTD, 2022-10)BACKGROUND: While physical inactivity is associated with adverse psychological outcomes, less is known about the psychological outcomes associated with sedentary behaviour, and specifically, its mentally active and passive forms. The COVID-19 pandemic represents a unique opportunity to study associations between these variables in light of widespread stay-at-home mandates and restrictions on outdoor exercise/social activities. Using a cross-sectional dataset acquired during the COVID-19 pandemic in Australia, we examined whether physical activity and sedentary behaviour were associated with subjective quality of life (sQoL) and subjective cognitive dysfunction, and whether these associations were mediated by depressive symptoms. METHODS: 658 participants (males = 169, females = 489) self-reported data on physical activity and sedentary behaviour in an online survey during May 2020-May 2021. Data on physical activity and sedentary behaviour (both mentally active and passive types) was compared according to whether it was collected during or out of a lockdown period. Regression models were used to test associations of physical activity and sedentary behaviour with sQoL and subjective cognitive dysfunction, and whether these associations were mediated by depression severity. RESULTS: Physical activity was beneficially associated with sQoL, whereas sedentary behaviour (both total hours and the reduction of mentally active/increase in mentally passive behaviour) was detrimentally associated with sQoL. These associations were mediated by depression severity. Physical activity and sedentary behaviour were also indirectly associated with subjective cognitive dysfunction by virtue of their associations with depression severity. CONCLUSIONS: There are important differences in the psychological correlates of mentally passive and active sedentary behaviours. Our findings suggest that health promotion strategies should focus on not only increasing physical activity but also reducing passive sedentary behaviours as a means of maintaining good psychological health.

The current study aimed to explore possible distal and proximal predictors contributing to schizotypy in a sample of the Australian general population during the COVID-19 pandemic. The COvid-19 and you: mentaL heaLth in AusTralia now survEy (COLLATE) project is an online mental health study aimed at tracking key mental health indicators over the progression of the pandemic. Adults residing in Australia were invited to take part using non-discriminative snowball sampling. Demographic-clinical information was collected for 850 participants in either October 2020 or January 2021. To assess schizotypy facets, the Launay-Slade Hallucinations Scale-Extended (LSHS-E) and Peters Delusions Inventory (PDI-21) were used to measure hallucination and delusion proneness respectively. Generalised linear models (with gamma and negative binomial distributions) were employed. Age, negative emotions and loneliness significantly contributed to both hallucination and delusion proneness; gender, education and religiosity also significantly contributed to delusion proneness, in the final regression models. Our study corroborated the specific contribution of loneliness, amongst other factors, in the prediction of schizotypy facets. Tackling loneliness represents a public health challenge that needs to be urgently addressed, especially in the face of the ongoing COVID-19 pandemic.

ItemSurviving the COVID-19 pandemic: An examination of adaptive coping strategies(ELSEVIER SCI LTD, 2022-05)The mental health consequences of the COVID-19 pandemic have been significant in Australia. The aim of this study was to investigate coping strategies that individuals have adopted to assist them through this stressful period. Survey data collected in September and December 2020 as part of a larger study (the COLLATE project) were analysed. The number of adaptive coping strategies endorsed by respondents had a significant negative relationship with depression and a significant positive relationship with resilience. Females tended to use more of these strategies than men, as did people who said their mental health had improved rather than deteriorated because of the COVID-19 restrictions imposed by government. Specific adaptive coping strategies differed for those with and without a mental illness. People with a mental illness were more likely to seek professional and online help, while people without a mental illness were more likely to use self-help. Focusing on what one is grateful for and keeping oneself productively occupied ("using the time to do things around the house") were the most beneficial coping strategies in terms of alleviating depression, anxiety and stress. Public health messaging promoting adaptive coping strategies may be useful in bolstering the mental health of individuals during lockdown periods. In particular, the promotion of coping flexibility should be recommended rather than the frequent use of the same coping strategies.

ItemNo Preview AvailableMental health of individuals with and without eating disorders across six months and two waves of COVID-19(ELSEVIER, 2021-12)PURPOSE: The COVID-19 global pandemic has resulted in a significant mental health toll, and recent findings suggest that individuals with an eating disorder (ED) history may be particularly vulnerable. The current study aimed to: (1) identify changes in the pattern of mental health symptoms over the first six months of the pandemic between individuals with an ED history, compared to a community sample without an ED history (non-ED); and (2) identify differences in mental health symptoms and concerns between two waves of the virus and associated lockdowns. METHOD: Data from 4915 respondents - 231 with an ED history - were compared across monthly time points from April to September 2020 on psychological symptoms including negative mood, quality of life, coping and hopefulness, as well as changes to eating and exercise behaviours. RESULTS: Mental health symptoms were increased in the ED group, but generally did not differ from non-ED in the pattern of symptoms reported over time. Increased depressive symptoms and restrictive eating behaviours were found across both groups in relation to the second wave/lockdown, as well as decreased hopefulness and quality of life. Respondents in both groups also reported coping worse during the second wave of the virus compared to the first wave. CONCLUSION: Although non-ED and ED groups tended to generally show the same pattern of symptoms, the mental health status of the ED group was significantly poorer than the non-ED group throughout the pandemic, and exacerbations in some symptoms (i.e. increased food restriction and depressive symptoms) is cause for concern.

ItemNo Preview AvailableMental health status of healthcare versus other essential workers in Australia amidst the COVID-19 pandemic: Initial results from the collate project(ELSEVIER IRELAND LTD, 2021-04)The novel coronavirus (COVID-19) has necessitated many healthcare workers operating on the frontlines. Another segment of the population whose mental well-being is being tested are the 'other essential workers' (e.g. supermarket workers). The current study aimed to compare the mental health of healthcare versus other essential workers in the early stages of the COVID-19 outbreak. The COVID-19 and you: mentaL heaLth in AusTralia now survEy (COLLATE) project is a nationwide online mental health survey launched on 1 April 2020, aimed at identifying key mental health concerns. Adults currently living in Australia were invited to take part, and non-discriminative snowball sampling was employed. Participants were partitioned into healthcare workers (HCW; n=905), other essential workers (OEW; n=810), and the general population (GNP; n=3443). Across all groups, top COVID-19 related concerns were primarily associated with the health and well-being of loved ones. In terms of current levels of depression, anxiety, stress and quality of life, HCWs fared the best, and OEWs fared the worst (with the GNP falling in between). In the face of this medical crisis, Australian HCWs seem to be managing their mental health relatively well, but more supports need to be devoted to OEWs to safeguard their mental well-being.

This study reports on the COLLATE project (COvid-19 and you: mentaL heaLth in AusTralia now survEy), an ongoing study aimed at understanding the impact of the COVID-19 pandemic on Australian mental health and well-being. We addressed prevailing primary concerns related to the COVID-19 pandemic, current levels of negative emotions and risk factors predicting negative emotions. On April 1st to 4th 2020, 5158 adults from the general public completed an online survey. Participants ranked their top ten current primary concerns about COVID-19, and completed standardized measures of negative emotions. The top three primary concerns were related to health and well-being of family and loved ones. Levels of negative emotion were high. Modelling of predictors of negative emotions established several risk factors related to demographic variables, personal vulnerabilities, financial stresses, and social distancing perceptions; particularly being young, female, or having a mental illness diagnosis. The data provides important characterization of the current Australian mental health. It appears that specific groups may need special attention to ensure their mental health is protected. These results may provide direction for international researchers characterizing similar issues.

Data on the mental health status of these individuals during the current pandemic is sparse, and their current mental health needs unclear. METHOD: We characterised COVID-19 related lifestyle changes, primary concerns and psychological distress in n=1292 respondents self-reporting a mood disorder (either bipolar disorder or depressive disorder) and n=3167 respondents without any reported mental disorder from the COLLATE (COvid-19 and you: mentaL heaLth in AusTralia now survEy) project; an Australian national survey launched on April 1st 2020. RESULTS: Psychological distress was heightened in the mood disorder group compared to the group with no mental disorder, with stress and depression further elevated in respondents with bipolar disorder compared to those with depressive disorder; and men with bipolar disorder having even higher levels of depression than women with bipolar disorder. Respondents with bipolar disorder were particularly concerned about financial issues associated with COVID-19 compared to those with depressive disorder and those with no mental disorder. Adverse changes to lifestyle behaviours were more prevalent in respondents with a mood disorder and linked to higher levels of distress. LIMITATIONS: Mood disorder was self-reported and was not clinically verified. CONCLUSIONS: Current psychological distress levels are elevated in individuals with mood disorder and are associated with maladaptive situational and lifestyle changes occurring in response to COVID-19.

ItemNo Preview AvailableAlcohol use in Australia during the early days of theCOVID-19 pandemic: Initial results from theCOLLATEproject(WILEY, 2020-10)AIM: The effects of social isolation measures used to control the spread of COVID-19 are negatively impacting the mental health of many. One of the consequences of exposure to disasters/pandemics is an increase in alcohol use. The current study aimed to examine what predisposing (distal) and pandemic-related (proximal) factors were associated with increased drinking in the wake of the COVID-19 pandemic. METHODS: On 1 April 2020, 5158 Australians completed a survey from the COvid-19 and you: mentaL heaLth in AusTralia now survEy (COLLATE) project, a nationwide study aimed at tracking key mental health concerns. Using logistic regression, distal (demographics and previous drinking behaviors) and proximal (employment, lifestyle factors, and mood) factors were assessed for their association with increased drinking since the onset of the COVID-19 pandemic. RESULTS: Distal factors, including heavier drinking pre-pandemic, middle age, and average or higher income, and proximal factors, including job loss, eating more, changes to sleep as well as stress and depression, were all associated with increased drinking in the COVID-19 pandemic environment. Female sex and self-reported history of mental illness became nonsignificant after proximal measures were added to the model. Living alone, exercise, anxiety, and status as an essential or health-care worker were not associated with increased drinking. CONCLUSION: These results provide guidance as to who might be targeted to receive support based on predisposing demographic factors and pre-pandemic drinking behavior. Second, they indicate what behaviors/factors accompany increased alcohol use and provide targets for psychosocial and psychoeducational supports to address these proximal factors.

ItemNo Preview AvailableEating and exercise behaviors in eating disorders and the general population during the COVID-19 pandemic in Australia: Initial results from the COLLATE project(WILEY, 2020-07)OBJECTIVE: Emerging evidence suggests that the coronavirus (COVID-19) pandemic may be negatively impacting mental health. The impact on eating and exercise behaviors is, however, currently unknown. This study aimed to identify changes in eating and exercise behaviors in an Australian sample among individuals with an eating disorder, and the general population, amidst the COVID-19 pandemic outbreak. METHOD: A total of 5,469 participants, 180 of whom self-reported an eating disorder history, completed questions relating to changes in eating and exercise behaviors since the emergence of the pandemic, as part of the COLLATE (COvid-19 and you: mentaL heaLth in AusTralia now survEy) project; a national survey launched in Australia on April 1, 2020. RESULTS: In the eating disorders group, increased restricting, binge eating, purging, and exercise behaviors were found. In the general population, both increased restricting and binge eating behaviors were reported; however, respondents reported less exercise relative to before the pandemic. DISCUSSION: The findings have important implications for providing greater monitoring and support for eating disorder patients during the COVID-19 pandemic. In addition, the mental and physical health impacts of changed eating and exercise behaviors in the general population need to be acknowledged and monitored for potential long-term consequences.
