Variation in sleep profiles in children with ADHD and associated clinical characteristics.

BACKGROUND: Sleep difficulties are common in children with attention-deficit/hyperactivity disorder (ADHD). However, sleep problems are multifaceted and little is known about the variation in sleep difficulties across children with ADHD. We examined the profiles of sleep difficulties in children with ADHD and associated clinical factors (e.g. co-occurring mental health conditions, stimulant use and parent mental health). METHODS: Data from two harmonised studies of children with ADHD (total: N = 392, ages 5-13 years) were used. Parents completed measures of children's sleep, co-occurring mental health conditions and their own mental health. Both parents and teachers completed measures of child ADHD symptoms and emotional and conduct symptoms. Latent profile analysis was used to identify sleep profiles, and multinomial logistic regression assessed clinical correlates of the groups. RESULTS: Five sleep profiles were identified: (a) insomnia/delayed sleep phase (36%), (b) generalised sleep difficulties at sleep onset and overnight (25%), (c) high anxious/bedtime resistance difficulties (11%), (d) overnight sleep difficulties including obstructive sleep apnoea and parasomnias (5%) and (e) no sleep difficulties (22%). Compared with the group without sleep difficulties, the generalised, anxious/bedtime resistance and insomnia/delayed sleep phase sleep had greater parent-reported emotional and conduct symptoms, co-occurring anxiety and increased parent mental health difficulties. The generalised and anxious/bedtime resistance groups also had greater parent-reported ADHD symptoms, with the anxious/bedtime resistance sleep group also having more frequent co-occurring depression and teacher-reported emotional symptoms. CONCLUSIONS: The sleep difficulties experienced by children with ADHD are varied. Supports to help children with ADHD need to consider the particular profiles of sleep difficulties experienced and broader clinical characteristics. Tailored intervention approaches are likely needed (including a need to address parent mental health).

It's gone, it's back: A prospective study on the COVID-19 pandemic-related shortages and mental health of Australian families.

Our aim was to explore the association between COVID-19 pandemic-related product shortages and symptoms of stress, anxiety, and depression in Australian families, concurrently and longitudinally, while controlling for demographic, health, and psychological characteristics. This prospective study used two waves of data (baseline, Time 0 = April 2020; Time 1 = May 2020) from a longitudinal cohort study of Australian parents of a child aged 0-18 years. Parents were surveyed at baseline about whether they had experienced product shortages related to COVID-19. DASS21 was used to measure symptoms of depression, anxiety, and stress at both waves. The sample included 2,110 participants (N = 1,701, 80.6% mothers). About 68.6% of the respondents reported being impacted by one or more shortages. Product shortages correlated significantly with higher combined and individual scores for anxiety, depression, and stress (r = 0.007 to 0.18, all p < 0.001) at baseline. At Time 1, parental emotion regulation explained 4.0% of the variance (p < .001). Our findings suggest a role for improving parental emotion regulation in coping with stressors, such as shortages and lockdowns.

Dietary behaviour as a form of collective action: A social identity model of vegan activism.

Adopting plant-based, or vegan, diets can have a number of benefits, including mitigating climate change, promoting animal welfare, or improving public health. In the current research, we use social psychological theory to better understand what motivates vegans to engage in collective action on behalf of this social group - that is, what motivates individuals to promote, or encourage others to adopt, a vegan lifestyle. We develop and test a Social Identity Model of Vegan Activism, which highlights the roles of individuals' social identities, sense of efficacy, emotions and moral convictions in fostering collective action. In two pre-registered studies, the first with self-identified vegans from Australia and the UK (N = 351), and the second with self-identified vegans from the UK and the US (N = 340), we found that individuals more frequently engaged in vegan activism (i.e., actions to promote vegan lifestyles) when they had stronger moral convictions (i.e., deontological or consequentialist), greater collective efficacy (i.e., beliefs that vegans can make a positive difference), anger (i.e., when thinking about the reasons why they are vegan), and identification (both with vegans, and with animals). Deontological and consequentialist moral convictions had significant indirect effects on vegan activism via different mediators. We conclude by discussing the implications and importance of studying dietary behavior from a social identity perspective, including its ability to help explain how and why individuals become motivated to not only adopt a certain (e.g., vegan) lifestyle themselves, but to also 'act collectively' on behalf of that shared group membership (e.g., promote vegan-friendly behaviors). We also highlight some key insights for policy makers and campaigners aiming to promote plant-based diets.

Climate change-related worry among Australian adolescents: an eight-year longitudinal study.

BACKGROUND: Worry about climate change may be associated with poorer mental health but also with greater political engagement. We determined trajectories of climate change-related worry over adolescence and whether these were associated with depression symptoms and greater engagement with news and politics in late adolescence. METHODS: At ages 10-11, 12-13, 16-17 and 18-19 years, adolescents participating in the Kindergarten cohort of the Longitudinal Study of Australian Children rated their worry about climate change. At age 18-19 years, participants reported on depression symptoms and engagement with news and politics. Latent profile analysis determined trajectories of climate change-related worry across all time points (N = 2244). Linear regression analyses examined the association between trajectories and outcomes at 18-19 years. RESULTS: Thirteen per cent (n = 290) of adolescents had high persistent worry. The largest proportions had moderate (n = 559, 24.9%) or increasing worry (n = 546, 24.3%), followed by persistent low worry (n = 376, 16.8%), slightly decreasing worry (n = 297, 13.2%) and steeply decreasing worry (n = 176, 7.8%). Adolescents with high persistent worry had higher depression symptoms at age 18-19 years compared to the moderate group, while those with increasing worry did not. The high persistent and increasing worry groups reported greater engagement with news and politics across several measures. CONCLUSION: This is the first study to track climate-related worry and outcomes in young people across adolescence. A substantial number of Australian adolescents experience high or increasing worry about climate change, which is associated with greater societal engagement.

Parent and child mental health trajectories April 2020 to May 2021: Strict lockdown versus no lockdown in Australia.

OBJECTIVE: To control a second-wave COVID-19 outbreak, the state of Victoria in Australia experienced one of the world's first long and strict lockdowns over July-October 2020, while the rest of Australia experienced 'COVID-normal' with minimal restrictions. We (1) investigate trajectories of parent/child mental health outcomes in Victoria vs non-Victoria and (2) identify baseline demographic, individual and COVID-19-related factors associated with mental health trajectories. METHODS: Online community sample of 2004 Australian parents with rapid repeated assessment over 14 time-points over April 2020 to May 2021. Measures assessed parent mental health (Depression, Anxiety and Stress Scales-21), child depression symptoms (13-item Short Mood and Feelings Questionnaire) and child anxiety symptoms (four items from Brief Spence Children's Anxiety Scale). RESULTS: Mental health trajectories shadowed COVID-19 infection rates. Victorians reported a peak in mental health symptoms at the time of the second-wave lockdown compared to other states. Key baseline predictors, including parent and child loneliness (standardized regression coefficient [ß] = 0.09-0.46), parent/child diagnoses (ß = 0.07-0.21), couple conflict (ß = 0.07-0.18) and COVID-19 stressors, such as worry/concern about COVID-19, illness and loss of job (ß = 0.12-0.15), predicted elevated trajectories. Effects of predictors on parent and child mental health trajectories are illustrated in an online interactive app for readers (https://lingtax.shinyapps.io/CPAS_trend/). CONCLUSION: Our findings provide evidence of worse trajectories of parent and child mental health symptoms at a time coinciding with a second COVID-19 outbreak involving strict lockdown in Victoria, compared to non-locked states in Australia. We identified several baseline factors that may be useful in detecting high-risk families who are likely to require additional support early on in future lockdowns.

Insights into adolescent well-being from computerised analysis of written language.

AIM: To examine associations between patterns of language use and early adolescent well-being. METHODS: Participants were 1763 Australian 11- to 12-year-olds in the Child Health CheckPoint. Six patterns of language use were identified from a writing activity using Linguistic Inquiry and Word Count and factor analysis: Acting in the present and future, Positive emotion, Gender and relationships, Self-aware, Inquisitive and time focused, and Confident. Well-being measures represented a spectrum from negatively to positively framed psychosocial health. Associations between language use and well-being were estimated using linear regression adjusted for age, sex and social disadvantage. RESULTS: Positive emotion (high emotional tone, positive emotion) was associated with better general well-being (standardised regression coefficient (SRC) 0.05; 95% confidence interval 0.00 to 0.11; p = 0.04), life satisfaction (0.06; 0.01 to 0.11; p = 0.03), psychosocial health (0.07; 0.02 to 0.12; p = 0.01) and quality of life (QoL) (0.06; 0.01 to 0.11; p = 0.02). Similarly, Self-aware (high first person singular pronouns, authentic, low clout) was associated with better general well-being, life satisfaction and psychosocial health (SRC 0.05, 0.09, 0.08), but Confident (high clout, first person plural pronouns, affiliation) was associated with worse life satisfaction, psychosocial health and QoL (SRC -0.06, -0.09, -0.06). CONCLUSION: If replicated in 'real-world' settings (e.g., social media), language patterns could provide naturalistic insights into early adolescents' well-being.

Study Protocol for the COVID-19 Pandemic Adjustment Survey (CPAS): A Longitudinal Study of Australian Parents of a Child 0-18 Years.

BACKGROUND: The COVID-19 pandemic presents significant risks to the mental health and wellbeing of Australian families. Employment and economic uncertainty, chronic stress, anxiety, and social isolation are likely to have negative impacts on parent mental health, couple and family relationships, as well as child health and development. OBJECTIVE: This study aims to: (1) provide timely information on the mental health impacts of the emerging COVID-19 crisis in a close to representative sample of Australian parents and children (0-18 years), (2) identify adults and families most at risk of poor mental health outcomes, and (3) identify factors to target through clinical and public health intervention to reduce risk. Specifically, this study will investigate the extent to which the COVID-19 pandemic is associated with increased risk for parents' mental health, lower well-being, loneliness, and alcohol use; parent-parent and parent-child relationships (both verbal and physical); and child and adolescent mental health problems. METHODS: The study aims to recruit a close to representative sample of at least 2,000 adults aged 18 years and over living in Australia who are parents of a child 0-4 years (early childhood, N = 400), 5-12 years (primary school N = 800), and 13-18 years (secondary school, N = 800). The design will be a longitudinal cohort study using an online recruitment methodology. Participants will be invited to complete an online baseline self-report survey (20 min) followed by a series of shorter online surveys (10 min) scheduled every 2 weeks for the duration of the COVID-19 pandemic (i.e., estimated to be 14 surveys over 6 months). RESULTS: The study will employ post stratification weights to address differences between the final sample and the national population in geographic communities across Australia. Associations will be analyzed using multilevel modeling with time-variant and time-invariant predictors of change in trajectory over the testing period. CONCLUSIONS: This study will provide timely information on the mental health impacts of the COVID-19 crisis on parents and children in Australia; identify communities, parents, families, and children most at risk of poor outcomes; and identify potential factors to address in clinical and public health interventions to reduce risk.

Folk Theories of Artifact Creation: How Intuitions About Human Labor Influence the Value of Artifacts.

What are the consequences of lay beliefs about how things are made? In this article, we describe a Western folk theory of artifact creation, highlighting how intuitive dualism regarding mental and physical labor (i.e., folk psychology) can lead to the perceived transmission of properties from makers to material artifacts (i.e., folk physics), and affect people's interactions with material artifacts. We show how this folk theory structures the conceptual domain of material artifacts by differentiating the contemporary lay concepts of art/craft and industrial production, and how it influences people's evaluations of different types of artifacts and their makers. We propose that the folk theory and lay concepts of art/craft and industrial production are best understood within a specific sociohistorical context, and review potential sources of cross-cultural and cross-temporal variation. We conclude by making recommendations for future research and examining the implications for promoting environmental sustainability and social justice in production systems.

Functions of Utopia: How Utopian Thinking Motivates Societal Engagement.

Images of ideal societies, utopias, are all around us; yet, little is known of how utopian visions affect ordinary people's engagement with their societies. As goals for society, utopias may elicit processes of collective self-regulation, in which citizens are critical of, or take action to change, the societies they live in. In three studies, we investigated the psychological function of utopian thinking. In Study 1, measured utopianism was correlated with the activation of three utopian functions: change, critique, and compensation. In Study 2, primed utopian thinking consistently enhanced change and criticism intentions. Study 3 also provided evidence that mental contrasting-first imagining a utopian vision and then mentally contrasting the current society to this vision-underlies the facilitative effect of utopian thinking on societal engagement.

Alternatives to the fixed-set model: A review of appraisal models of emotion.

Over several decades, appraisal theory has emerged as a prominent theoretical framework explaining the elicitation and differentiation of emotions, and has stimulated a great deal of theorising and empirical research. Despite the large amount of research in this area, there are many aspects of appraisal theory and research that remain unclear or problematic. In this review, we identify a common assumption of many appraisal theories-the fixed appraisal set-and argue that this assumption, combined with a lack of explicit theorising about the predicted relationship between appraisals and emotions, leads to a lack of clarity in both appraisal models and the empirical testing of those models. We recommend that appraisal theorists move in a direction already taken by a small number of theorists, and adopt the starting assumption of a variable appraisal set. We further suggest that theories of concepts and categorisation may inform theorising about appraisal-emotion relationships.

Multiple emotions: a person-centered approach to the relationship between intergroup emotion and action orientation.

Although a great deal of research has investigated the relationship between emotions and action orientations, most studies to date have used variable-centered techniques to identify the best emotion predictor(s) of a particular action. Given that people frequently report multiple or blended emotions, a profitable area of research may be to adopt person-centered approaches to examine the action orientations elicited by a particular combination of emotions or "emotion profile." In two studies, across instances of intergroup inequality in Australia and Canada, we examined participants' experiences of six intergroup emotions: sympathy, anger directed at three targets, shame, and pride. In both studies, five groups of participants with similar emotion profiles were identified by cluster analysis and their action orientations were compared; clusters indicated that the majority of participants experienced multiple emotions. Each action orientation was also regressed on the six emotions. There were a number of differences in the results obtained from the person-centered and variable-centered approaches. This was most apparent for sympathy: the group of participants experiencing only sympathy showed little inclination to perform prosocial actions, yet sympathy was a significant predictor of numerous action orientations in regression analyses. These results imply that sympathy may only prompt a desire for action when experienced in combination with other emotions. We suggest that the use of person-centered and variable-centered approaches as complementary analytic strategies may enrich research into not only the affective predictors of action, but emotion research in general.
