Abstract
OBJECTIVE Online youth-focused health programs often include parent modules-that equip parents with skills to assist their child in improving their health-alongside youth-specific content. BRAVE Self-Help, an evidence-based program designed for children and teenagers with early signs of anxiety, is a popular Australian program that includes six parent modules. Despite its popularity and proven efficacy, BRAVE Self-Help shares the same challenge as many online self-help programs-that of low participant engagement. Using parents registered in BRAVE Self-Help as 'information rich' participants, we explored (a) factors that influenced parent engagement in online health programs, and (b) their recommendations for enhancing parent engagement. DESIGN AND OUTCOME MEASURE We conducted semi-structured interviews with 14 parents registered in BRAVE Self-Help. Data were analysed through reflexive thematic analysis. RESULTS Social-, family- and program-related factors drove parents' program engagement and recommendations. Social sub-themes related to the benefits of professional and community support in promoting more engagement. Family sub-themes included difficulties with program engagement due to competing priorities, perceptions that condition severity influenced engagement, and feelings that previously-acquired health knowledge reduced motivation to engage. Program sub-themes included perceived usefulness and ease-of-use. CONCLUSION Program designers could target support systems, include flexible delivery options, and use iterative design processes to enhance parent engagement.

Abstract
OBJECTIVE Gratitude has consistently been associated with various beneficial health-related outcomes, including subjective wellbeing, positive mental health, and positive physical health. In light of such effects, positive psychology researchers and practitioners have often implemented gratitude interventions in an attempt to build individuals' orientations toward appreciation and thankfulness. Recent meta-analyses and reviews have revealed, however, that these interventions often have mixed effects on gratitude or other health outcomes. With this issue in mind, we aimed to identify (a) contextual considerations that may impact the effectiveness of these approaches, and (b) recommendations for the optimisation of gratitude interventions. METHODS AND MEASURES Seventeen mental health professionals or experienced health psychology researchers engaged in semi-structured interviews to address the research questions. RESULTS Thematic analysis of the data resulted in three contextual themes-cultural considerations, personal characteristics, and life experience-that were discussed as factors likely to influence intervention effectiveness. With respect to recommendations, participants highlighted the importance of encouraging deep engagement in gratitude tasks, consistent repetition of those tasks, and the value of interpersonal expressions of gratitude. CONCLUSION Discussion is centred on suggestions for future research on gratitude and on implications for the implementation of gratitude interventions.

Abstract
Physical literacy development in early childhood, viewed by many as the foundation for lifelong physical activity engagement, is significantly influenced by parents. Our aim was to explore parents' understanding of physical literacy and gain insight into their perspectives on physical literacy promotion. We recruited 18 parents of children between 5 and 8 years old in Australia. Using semistructured interviews and thematic analysis, we identified several key issues regarding parents' understanding and implementation of physical literacy. Parents expressed interest in improving their implementation of physical literacy practices and had (often unintentionally) provided support for physical literacy subcomponents in the past. However, they described difficulties prioritizing physical literacy above other parental demands and expressed conflicting perceptions regarding where the responsibility should lie for developing their child's physical literacy (e.g., at home or at school). To ensure that the physical literacy "message" reaches parents, we encourage physical literacy promoters to consider the target (e.g., responsibility, priorities, and awareness) of their promotional strategies. Further investigation into the influence of sociocultural and economic factors on parents' understanding and application of physical literacy is warranted.

Abstract
Porcine reproductive and respiratory syndrome viruses (PRRSV-1 and -2) are the causative agents of one of the most important infectious diseases affecting the global pig industry. Previous studies, largely focused on PRRSV-2, have shown that non-structural protein-1α (NSP1α) and NSP1β modulate host cell responses; however, the underlying molecular mechanisms remain to be fully elucidated. Therefore, we aimed to identify novel PRRSV-1 NSP1-host protein interactions to improve our knowledge of NSP1-mediated immunomodulation. NSP1α and NSP1β from a representative western European PRRSV-1 subtype 1 field strain (215-06) were used to screen a cDNA library generated from porcine alveolar macrophages (PAMs), the primary target cell of PRRSV, using the yeast-2-hybrid system. This identified 60 putative binding partners for NSP1α and 115 putative binding partners for NSP1β. Of those taken forward for further investigation, 3 interactions with NSP1α and 27 with NSP1β were confirmed. These proteins are involved in the immune response, ubiquitination, nuclear transport, or protein expression. Increasing the stringency of the system revealed NSP1α interacts more strongly with PIAS1 than PIAS2, whereas NSP1β interacts more weakly with TAB3 and CPSF4. Our study has increased our knowledge of the PRRSV-1 NSP1α and NSP1β interactomes, further investigation of which could provide detailed insight into PRRSV immunomodulation and aid vaccine development.

Abstract
Rates of mental illness are disproportionately high for young adult and higher education (e.g., university student) populations. As such, universities and tertiary institutions often devote significant efforts to services and programs that support and treat mental illness and/or mental distress. However, within that portfolio of treatment approaches, structured exercise has been relatively underutilised and greater research attention is needed to develop this evidence base. The Stride program is a structured 12-week exercise service for students experiencing mental distress. We aimed to explore the feasibility of the program and assess pre- and post-program change, through assessments of student health, lifestyle, and wellbeing outcomes. Drawing from feasibility and effectiveness-implementation hybrid design literatures, we conducted a non-randomised feasibility trial of the Stride program. Participants were recruited from the Stride program (N = 114, Mage = 24.21 years). Feasibility results indicated the program was perceived as acceptable and that participants reported positive perceptions of program components, personnel, and sessions. Participants' pre-to-post program change in depressive symptomatology, physical activity levels, mental health-related quality of life, and various behavioural outcomes were found to be desirable. Our results provide support for the feasibility of the Stride program, and more broadly for the delivery and potential effectiveness of structured exercise programs to support university students experiencing mental distress.

Abstract
Family-based lifestyle interventions for children/adolescents with severe levels of obesity are numerous, but evidence indicates programs fail to elicit short- or longer-term weight loss outcomes. Families with lived experience can provide valuable insight as we strive to improve outcomes from programs. Our aim was to explore elements that families desired in a program designed to treat severe levels of obesity in young people. We recruited a cross-sectional sample of 13 families (parents and young people) who had been referred but had not engaged with the state-wide Perth Children's Hospital, Healthy Weight Service (Perth, Australia), between 2016 and 2018. Utilizing semi-structured interviews and reflexive qualitative thematic analysis, we identified two broad themes, (1) bridging the gap between what to do and how to do it, and (2) peers doing it with you. The first theme reflected parents' and young people's feelings that programs ought to teach specialist-designed practical strategies utilizing non-generic information tailored to address the needs of the family, in a collaboratively supportive way, and encourage young people to learn for themselves. The second theme reflected the importance of social connection facilitated by peer support, and intervention programs should be offered in a group format to foster inclusion. Families indicated a willingness to engage in tertiary intervention programs but desired support from specialized health professionals/programs to be tailored to their needs, sensitive to their experiences and challenges and provide useful practical strategies that support the knowledge-to-action process.

Abstract
Objectives and importance of study: Being physically active is critical for healthy ageing, yet many older people do not meet physical activity guidelines. The aim of this study was to test the relative effectiveness of five previously identified campaign slogans designed to encourage older people to be more physically active: 'Be active 30-60 minutes a day to stay fit and well'; 'Move more, live longer'; 'Stay fit to stay functional'; 'This is your time - enjoy being strong and active'; and 'Use it or lose it'. STUDY TYPE Online experiment Methods: A total of 1200 Australians aged 50 years and older (50% female, mean age 65 years) were recruited to complete an online survey, with respondents randomised to answer a series of questions on a video featuring one of the five slogan conditions. One-way ANOVAs with Tukey's post-hoc tests were used to identify differences in outcomes between slogans. RESULTS Overall, the slogans were assessed favourably, suggesting older adults may be receptive to messages about increasing their physical activity. 'Use it or lose it 'performed best across the outcome measures of internal and external motivation, perceived effectiveness, liking, believability, and personal relevance. CONCLUSION Efforts to encourage physical activity among older Australians could use the slogan 'Use it or lose it' as an evidence-based tagline.

Abstract
INTRODUCTION Early childhood is recognised as a critical window of opportunity for physical literacy development, however early childhood educators typically lack the training required to effectively provide appropriate physical literacy opportunities for children. We examined the effects of an online physical literacy professional development program-relative to continuing with 'standard' practice-on early childhood educators' physical literacy knowledge and application. METHODS We conducted a parallel two-arm randomised controlled trial, in which 88 early childhood educators were randomly assigned to an online professional development program designed to support educators' physical literacy instructional skills (intervention arm; n = 37), or a 'standard practice' control condition (n = 51). Data were collected prior to and after the four-week intervention period. We measured educators' physical literacy knowledge and application (our primary outcome) through independent coding of open-ended survey responses, and educators' self-reported perceptions of values, confidence, behaviours, and barriers (secondary outcomes). Between-group differences were assessed through analysis of covariance. RESULTS One intervention arm participant withdrew from the study, resulting in 87 participants included in analysis. Educators in the intervention arm scored significantly higher on post-intervention physical literacy knowledge (d = 0.62) and application (d = 0.33) than those in the control arm. Educators in the intervention arm also scored significantly higher than controls on confidence in teaching physical activity (d = 0.42) and significantly lower than controls on perceived personal barriers to physical activity (d = 0.53). Thirteen participants in the intervention arm (36%) did not begin the online professional development program. CONCLUSION Improvements in physical literacy instructional outcomes indicate the potential for further investigation into broader implementation of online professional development programs of this nature in the future.

Abstract
Marek's disease virus (MDV) causes a deadly lymphoproliferative disease in chickens, resulting in huge economic losses in the poultry industry. It has been suggested that MDV suppresses the induction of type I interferons and thus escapes immune control. Cholesterol 25-hydroxylase (CH25H), a gene that encodes an enzyme that catalyses cholesterol to 25-hydroxycholesterol (25-HC), is an interferon-stimulating gene (ISG) known to exert antiviral activities. Other oxysterols, such as 27-hydroxycholesterols (27-HC), have also been shown to exert antiviral activities, and 27-HC is synthesised by the catalysis of cholesterol via the cytochrome P450 enzyme oxidase sterol 27-hydroxylase A1 (CYP27A1). At 24 h post infection (hpi), MDV stimulated a type I interferon (IFN-α) response, which was significantly reduced at 48 and 72 hpi, as detected using the luciferase assay for chicken type I IFNs. Then, using RT-PCR, we demonstrated that chicken type I IFN (IFN-α) upregulates chicken CH25H and CYP27A1 genes in chicken embryo fibroblast (CEF) cells. In parallel, our results demonstrate a moderate and transient upregulation of CH25H at 48 hpi and CYP27A1 at 72hpi in MDV-infected CEF cells. A significant reduction in MDV titer and plaque sizes was observed in CEFs treated with 25-HC or 27-HC in vitro, as demonstrated using a standard plaque assay for MDV. Taken together, our results suggest that 25-HC and 27-HC may be useful antiviral agents to control MDV replication and spread.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) now arise in the context of heterogeneous human connectivity and population immunity. Through a large-scale phylodynamic analysis of 115,622 Omicron BA.1 genomes, we identified >6,000 introductions of the antigenically distinct VOC into England and analyzed their local transmission and dispersal history. We find that six of the eight largest English Omicron lineages were already transmitting when Omicron was first reported in southern Africa (22 November 2021). Multiple datasets show that importation of Omicron continued despite subsequent restrictions on travel from southern Africa as a result of export from well-connected secondary locations. Initiation and dispersal of Omicron transmission lineages in England was a two-stage process that can be explained by models of the country's human geography and hierarchical travel network. Our results enable a comparison of the processes that drive the invasion of Omicron and other VOCs across multiple spatial scales.

Abstract
OBJECTIVE For parents and guardians, assisting children/adolescents with severe obesity to lose weight is often a key objective but a complex and difficult challenge. Our aim in this study was to explore parents' (and guardians') perspectives on the challenges they have faced in assisting their children/adolescents with severe obesity to lead a healthy lifestyle. METHODS Thirteen parents/guardians were interviewed from a pool of families who had been referred but did not engage between 2016 and 2018 (N = 103), with the Perth Children's Hospital Healthy Weight Service, a clinical obesity program for children/adolescents (parent age M = 43.2 years, children age M = 10.3 years). Using semi-structured interviews and thematic analysis, we identified 3 broad themes. RESULTS Parental weight-related factors reflected parents' own lifelong obesity narrative and its effect on their own and their families' ability to live a healthy lifestyle. Perceived inevitability of obesity in their child reflected parents' feelings that the obesity weight status of their children/adolescent was a persistent and overwhelming problem that felt 'out of control'. Lastly, parents reported challenges getting medical help stemming from co-morbid medical diagnosis in their child/adolescent, and difficulties with medical professionals. CONCLUSION This study demonstrates that parents face challenges in supporting healthy lifestyle for children/adolescents with severe obesity due to parents own internal weight biases and their negative experiences within the healthcare system when seeking help.

Abstract
Health-related behaviours contribute to the global burden of cardiovascular disease (CVD). Cardiovascular imaging can be used to screen asymptomatic individuals for increased risk of CVD to enable earlier interventions to promote health-related behaviours to prevent or reduce CVD risk. Some theories of behaviour and behaviour change assume that engagement in a given behaviour is a function of individual threat appraisals, beliefs regarding the performance of behaviour, self-efficacy for performing the desired behaviour and/or dispositions to act (e.g. behavioural intentions). To date, little is known about the impact of cardiovascular imaging interventions on these constructs. This article summarises evidence related to perceived threat, efficacy beliefs, and behavioural intentions after CVD screening. We identified 10 studies (2 RCTs and 8 non-randomised studies, n = 2498) through a combination of screening citations from published systematic reviews and meta-analyses and searching electronic databases. Of these, 7 measured behavioural intentions and perceived susceptibility and 3 measured efficacy beliefs. Findings showed largely encouraging effects of screening interventions on bolstering self-efficacy beliefs and strengthening behavioural intentions. Imaging results that suggest the presence of coronary or carotid artery disease also increased perceived susceptibility to CVD. However, the review also identified some gaps in the literature, such as a lack of guiding theoretical frameworks and assessments of critical determinants of health-related behaviours. By carefully considering the key issues highlighted in this review, we can make significant strides towards reducing CVD risks and improving population health.

Abstract
Despite there being an increasing number of applied flow studies across scientific disciplines, there exists no consistent or broadly applicable intervention to promote flow experiences. This study provides a detailed account of a new educational flow training program developed following recent advancements in the flow literature that have provided a more parsimonious understanding of flow experiences and antecedents. Guided by CONSORT guidelines for feasibility trials, we conducted a single-group, non-randomized feasibility trial of an educational flow training program (N = 26). We assessed participant retention, perceptions about and experiences of the program, perceptions about the flow education training, and preliminary assessments of flow as an outcome. Results broadly supported program feasibility, and participants reported positive experiences in, and perceptions of, program components. In terms of preliminary efficacy, we observed evidence of noteworthy change pre-to-post-program in flow (d = 0.84), performance (d = 0.81), competence (d = 0.96), well-being (d = 0.68), intrinsic motivation (d = 0.47), interest (d = 0.72), choice (d = 0.38), stress (d = -1.08), ability to handle stress (d = 0.74), and anxiety (d = - 0.86). These results provide preliminary evidence that it may be possible to 'train' flow in line with recent perspectives on a core three-dimensional flow experience (and antecedents). The study has developed a research foundation for flow intervention "curriculum" and quality standards, and for measuring results. It offers a foundation for the implementation of a larger-scale program. Supplementary Information The online version contains supplementary material available at 10.1007/s41042-023-00098-2.

Abstract
The incidence of mental illness is greatest among young adults, and those enrolled in higher education may be particularly vulnerable compared to the general young adult population. Many higher education institutions employ student support staff tasked with implementing strategies to improve student wellbeing and mental illness. However, these strategies tend to be focused on clinical therapies and pharmacological interventions with limited lifestyle approaches. Exercise is an effective method for addressing mental illness and promoting wellbeing, yet widespread provision of structured exercise services to support treatment options for students with mental health challenges has not been fully realized. In an effort to guide exercise strategies for student mental health, we synthesize considerations for developing and delivering exercise programs in higher education settings. We draw directly from the evidence base on existing exercise programs in higher education; and the broader behavior change, exercise adherence, health psychology, implementation science, and exercise prescription literatures. Our broad considerations cover issues regarding program engagement and behavior change, exercise 'dose' and prescription, integration with other on-campus services, and robust research and evaluation. These considerations may provide impetus for widespread program development and implementation, as well as informing research focused on protecting and improving student mental health.

Abstract
INTRODUCTION Children and adolescents living in families affected by mental illness are at elevated risk of developing mental health problems. A range of interventions have been designed to help these young people; however, the effectiveness of these programs is, in some cases, mixed. Our aim was to understand in detail the support needs and experiences of a group of Australian children and adolescents living in families with mental illness. METHODS Our study is a qualitative in nature. In 2020-2021, we interviewed 25 Australian young people (Mage = 13.60, SD = 2.26, 20 females and 5 males) living with family members affected by mental illness to understand their (the young people's) experiences, and to identify the types of support that these young people considered important or effective. We conducted reflexive thematic analyses of interview data, underpinned by interpretivist assumptions. RESULTS We identified seven themes within two higher-order categories reflecting our aims to understand (1) lived experiences within families affected by mental illness (i.e., increased responsibilities, missing out, and stigmatization), and (2) support experiences, needs, and preferences (i.e., respite, shared experiences with like-minded others, education, and flexibility). CONCLUSIONS Our findings hold substantial practical value by informing services, interventions, and conversations that better support young people living in families affected by mental illness.

Abstract
BACKGROUND Current evidence supports the use of intravenous thrombolysis with alteplase in patients with wake-up stroke selected with MRI or perfusion imaging and is recommended in clinical guidelines. However, access to advanced imaging techniques is often scarce. We aimed to determine whether thrombolytic treatment with intravenous tenecteplase given within 4·5 h of awakening improves functional outcome in patients with ischaemic wake-up stroke selected using non-contrast CT. METHODS TWIST was an investigator-initiated, multicentre, open-label, randomised controlled trial with blinded endpoint assessment, conducted at 77 hospitals in ten countries. We included patients aged 18 years or older with acute ischaemic stroke symptoms upon awakening, limb weakness, a National Institutes of Health Stroke Scale (NIHSS) score of 3 or higher or aphasia, a non-contrast CT examination of the head, and the ability to receive tenecteplase within 4·5 h of awakening. Patients were randomly assigned (1:1) to either a single intravenous bolus of tenecteplase 0·25 mg per kg of bodyweight (maximum 25 mg) or control (no thrombolysis) using a central, web-based, computer-generated randomisation schedule. Trained research personnel, who conducted telephone interviews at 90 days (follow-up), were masked to treatment allocation. Clinical assessments were performed on day 1 (at baseline) and day 7 of hospital admission (or at discharge, whichever occurred first). The primary outcome was functional outcome assessed by the modified Rankin Scale (mRS) at 90 days and analysed using ordinal logistic regression in the intention-to-treat population. This trial is registered with EudraCT (2014-000096-80), ClinicalTrials.gov (NCT03181360), and ISRCTN (10601890). FINDINGS From June 12, 2017, to Sept 30, 2021, 578 of the required 600 patients were enrolled (288 randomly assigned to the tenecteplase group and 290 to the control group [intention-to-treat population]). The median age of participants was 73·7 years (IQR 65·9-81·1). 332 (57%) of 578 participants were male and 246 (43%) were female. Treatment with tenecteplase was not associated with better functional outcome, according to mRS score at 90 days (adjusted OR 1·18, 95% CI 0·88-1·58; p=0·27). Mortality at 90 days did not significantly differ between treatment groups (28 [10%] patients in the tenecteplase group and 23 [8%] in the control group; adjusted HR 1·29, 95% CI 0·74-2·26; p=0·37). Symptomatic intracranial haemorrhage occurred in six (2%) patients in the tenecteplase group versus three (1%) in the control group (adjusted OR 2·17, 95% CI 0·53-8·87; p=0·28), whereas any intracranial haemorrhage occurred in 33 (11%) versus 30 (10%) patients (adjusted OR 1·14, 0·67-1·94; p=0·64). INTERPRETATION In patients with wake-up stroke selected with non-contrast CT, treatment with tenecteplase was not associated with better functional outcome at 90 days. The number of symptomatic haemorrhages and any intracranial haemorrhages in both treatment groups was similar to findings from previous trials of wake-up stroke patients selected using advanced imaging. Current evidence does not support treatment with tenecteplase in patients selected with non-contrast CT.

Abstract
AIMS Psychological distress and changes in health-related quality of life (HRQoL) may occur after screening for disease. Reporting outcomes related to potential benefits and harms of screening is a key recommendation in the guidelines for reporting high-quality trials or interventions. However, no reviews have directly investigated outcomes related to psychological distress and/or changes in HRQoL following imaging assessment of cardiovascular risk and communication of cardiovascular findings to asymptomatic adults. A scoping review was conducted to map research on psychological distress and/or HRQoL following screening. METHODS AND RESULTS Six electronic databases (MEDLINE, PsychINFO, Social Work Abstracts, Psychology and Behavioural Sciences Collection, CINAHL, and EMBASE) were searched for articles that assessed psychological distress and/or HRQoL following screening. Two investigators independently screened titles and abstracts for all records retrieved using predefined criteria. Studies were conducted among active smokers, military personnel, athletes, post-menopausal women, and high-risk individuals. Seven constructs related to psychological distress and HRQoL appeared across 11 articles (randomized controlled trials, n = 4 and non-randomized studies, n = 7). Worry, depression, perceived stress, anxiety, and quality of life were most prominent. Multiple-item measures of psychological distress (e.g. Taylor Anxiety Score and Beck Depression Inventory) were used in 5/9 (56%) studies. Key findings on psychological distress and/or changes in HRQoL following screening were mixed. CONCLUSIONS Findings support the need for multiple-item measures with better psychometric properties to examine the psychological responses to screening results in future studies. Strategies to support individuals during and following vascular screening to maximise potential benefits of screening and minimize harms are discussed.

Abstract
Self-affirmations-responding to self-threatening information by reflecting on positive values or strengths-help to realign working self-concept and may support adaptive coping and wellbeing. Little research has been undertaken on spontaneous self-affirmations in response to everyday threats, and less has been undertaken on the relationships between spontaneous self-affirmations, coping, and wellbeing. This study aimed to test both within- and between-person relationships between spontaneous self-affirmations, coping, and wellbeing, controlling for threat intensity and other outcomes. A repeated survey assessment design was adopted to achieve these aims. Outcome measures included approach coping, avoidance coping, positive affect, negative affect, and eudaimonic wellbeing. It was found that spontaneous self-affirmations positively predicted approach coping and positive affect at both within- and between-person levels, and eudaimonic wellbeing at the between-person level. Overall, spontaneous self-affirmations were positively associated with approach coping and aspects of wellbeing.

Abstract
Background Although a healthy diet and physical activity have been shown to prevent or delay cardiovascular disease (CVD) hospitalizations and deaths, most adults do not meet current guidelines. Provision of coronary artery calcification (CAC) and carotid ultrasound (CUS) imaging results may motivate beneficial lifestyle changes. We scoped the existing literature for studies providing non-invasive vascular imaging results and reporting diet, physical activity, and/or anthropometric measures to identify knowledge gaps and opportunities for further research. Methods A systematic search was performed across three electronic databases, in line with PRISMA ScR guidelines and Arksey and O'Malley's scoping review framework. Results Twenty studies (thirteen observational and seven randomized controlled trials) examining the impact of provision of CAC/CUS imaging results on diet and/or physical activity behaviors were included. Nearly half the studies did not clearly state whether participants received dietary and physical activity advice along with vascular imaging results, and these were secondary outcomes in most studies, with data assessment and reporting being inconsistent. Conclusion Well-designed clinical trials with consistent and clear messaging based on detailed subjective and objective measures of diet and physical activity are needed to determine whether this approach may stimulate long-term dietary and physical activity change.

Abstract
(1) Background: The transition to motherhood can be challenging, especially for first-time mothers, and can accompany maternal distress. Social support—such as that offered by peers—can be important in assisting mothers to manage such distress. Although primiparous mothers often seek out and value peer support programs, few researchers have investigated factors that may influence the strength of relationships in non-professional maternal peer support programs. Insight into these factors can be key to enhancing the success of future peer support interventions. (2) Methods: Reflexive thematic analysis was applied to data gathered from 36 semi-structured interviews conducted with 14 primiparous mothers and 17 peer mentors in a peer support program. (3) Results: Four themes related to successful mentorship were identified: expectations of peer relationship, independence of peer mentor, contact, and similarities. (4) Conclusions: For primiparous mothers who are developing their support network, these factors appear important for promoting close and effective peer support relationships. Interventions that harness the dynamics between these factors may contribute to more successful peer support relationships and mental health outcomes for participants.

Abstract
The SARS-CoV-2 Delta (Pango lineage B.1.617.2) variant of concern spread globally, causing resurgences of COVID-19 worldwide1,2. The emergence of the Delta variant in the UK occurred on the background of a heterogeneous landscape of immunity and relaxation of non-pharmaceutical interventions. Here we analyse 52,992 SARS-CoV-2 genomes from England together with 93,649 genomes from the rest of the world to reconstruct the emergence of Delta and quantify its introduction to and regional dissemination across England in the context of changing travel and social restrictions. Using analysis of human movement, contact tracing and virus genomic data, we find that the geographic focus of the expansion of Delta shifted from India to a more global pattern in early May 2021. In England, Delta lineages were introduced more than 1,000 times and spread nationally as non-pharmaceutical interventions were relaxed. We find that hotel quarantine for travellers reduced onward transmission from importations; however, the transmission chains that later dominated the Delta wave in England were seeded before travel restrictions were introduced. Increasing inter-regional travel within England drove the nationwide dissemination of Delta, with some cities receiving more than 2,000 observable lineage introductions from elsewhere. Subsequently, increased levels of local population mixing-and not the number of importations-were associated with the faster relative spread of Delta. The invasion dynamics of Delta depended on spatial heterogeneity in contact patterns, and our findings will inform optimal spatial interventions to reduce the transmission of current and future variants of concern, such as Omicron (Pango lineage B.1.1.529).

Abstract
MAN v FAT Soccer is a sport-based weight-loss program for overweight and obese men that originated in the United Kingdom (i.e., as MAN v FAT Football) and appears to successfully engage men with weight loss. We sought to explore whether the program would work in an Australian context by (a) establishing a foundation for the implementation of the program on a larger scale and (b) determining how large-scale implementation is most feasible. We conducted a nonrandomized, single intervention group feasibility trial of MAN v FAT Soccer in Australia with 418 male participants with a body mass index greater than 27.50 kg/m2. Results indicate that the program is acceptable, with participants reporting positive perceptions of the various components of the program and a high proportion reporting intentions to recommend the program to others (95.9%). Furthermore, preliminary effectiveness results indicate positive changes in weight (4.6% reduction) and physical activity (88.5% increase) and improvements in psychological outcomes such as depression (17.6% decrease), stress (19.0% decrease), and body appreciation (19.1% increase). Our findings provide general support for the feasibility of MAN v FAT Soccer and the notion that leveraging competition and masculinity may help drive men's health behavior change.

Abstract
ISSUE ADDRESSED Older adults are significantly less likely than their younger counterparts to engage in physical activity. Comprehensive policies to support healthy ageing thus need to include components encouraging greater participation in physical activity in later life. This study tested potential messages for use in health communication campaigns aimed at increasing physical activity among older adults. METHODS Twelve written messages designed to encourage older adults to increase their levels of physical activity were rated by Australians aged 60-92 years (n = 369; 54% female) on the variables of likeability and perceived effectiveness. RESULTS Ratings for all the tested messages were high across both outcome variables. The message Move more, live longer scored most favourably, with large majorities of participants liking this message (87%) and considering it effective (81%). Messages featuring rhyming or alliteration were rated significantly higher on both outcomes than messages without these attributes (all Ps < .001). CONCLUSIONS Results provide insights into the types of messages that are likely to be accepted by older adults. Statements that use the phonological patterns of rhyming or alliteration are likely to be especially well received. SO WHAT?: Increasing participation in physical activity among older adults is critical to promoting the sustainability of health care systems and enhancing quality of life. The specific messaging attributes identified in the present study as being effective could be used by public health practitioners to inform their approach to physical activity messaging to older adults and incorporated into future health communication campaigns to increase their potential effectiveness with this target group.

Abstract
OBJECTIVE Pole dancing is a challenging physical activity. Prospective injury studies in pole dancing are lacking. The aim of this study was to describe the incidence, mechanisms, and characteristics of injuries in pole dancers. METHODS A total of 66 pole dancers from 41 studios across Australia were prospectively followed over 12 months. An intake questionnaire was administered including items on pole dancers' demographics and training characteristics. Exposure was assessed using a daily online training diary. Self-reported injury data were collected via an incident report form and subsequently coded using the Orchard Sports Injury Classification System. Injuries occurring during pole-specific and pole-related activities were included in the analyses. RESULTS The sample included 63 females and 3 males, mean age 32.3 ± 8.9 years and mean pole training experience 3.5 ± 2.8 years. 25 of 66 participants completed the full study. The 1-year incidence of all new injuries was 8.95/1,000 exposure hours (95% CI 6.94 - 10.96), 7.65/1,000 hrs (95% CI 5.79 - 9.51) for pole-specific injuries and 1.29/1,000 hrs (95% CI 0.53 - 2.06) for pole-related injuries. A total of 103 injuries occurred, 62.1% of which were sudden onset and 37.9% gradual onset. Mechanism of onset included 54.4% acute and 45.6% repetitive in nature. Shoulder (20.4%) and thigh (11.7%, majority ham¬string) were the most reported anatomic injury sites. Non-contact mechanisms accounted for the majority of injuries (57.3%). The most reported primary contributor to injury onset at the shoulder were manoeuvres characterised by loaded internal humeral rotation (33.3%), and at the hamstring were manoeuvres and postures involving front splits (100.0%). CONCLUSION The findings indicate that pole dancers are at high risk for injuries. Future research is needed to understand the biomechani¬cal demand of manoeuvres and training characteristics of pole dancing (e.g., workload and recovery) to guide the development of preventative interventions, particularly targeted toward the shoulder and hamstring.

Abstract
Three lineages (BA.1, BA.2 and BA.3) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern predominantly drove South Africa's fourth Coronavirus Disease 2019 (COVID-19) wave. We have now identified two new lineages, BA.4 and BA.5, responsible for a fifth wave of infections. The spike proteins of BA.4 and BA.5 are identical, and similar to BA.2 except for the addition of 69-70 deletion (present in the Alpha variant and the BA.1 lineage), L452R (present in the Delta variant), F486V and the wild-type amino acid at Q493. The two lineages differ only outside of the spike region. The 69-70 deletion in spike allows these lineages to be identified by the proxy marker of S-gene target failure, on the background of variants not possessing this feature. BA.4 and BA.5 have rapidly replaced BA.2, reaching more than 50% of sequenced cases in South Africa by the first week of April 2022. Using a multinomial logistic regression model, we estimated growth advantages for BA.4 and BA.5 of 0.08 (95% confidence interval (CI): 0.08-0.09) and 0.10 (95% CI: 0.09-0.11) per day, respectively, over BA.2 in South Africa. The continued discovery of genetically diverse Omicron lineages points to the hypothesis that a discrete reservoir, such as human chronic infections and/or animal hosts, is potentially contributing to further evolution and dispersal of the virus.

Abstract
The first SARS-CoV-2 variant of concern (VOC) to be designated was lineage B.1.1.7, later labelled by the World Health Organization as Alpha. Originating in early autumn but discovered in December 2020, it spread rapidly and caused large waves of infections worldwide. The Alpha variant is notable for being defined by a long ancestral phylogenetic branch with an increased evolutionary rate, along which only two sequences have been sampled. Alpha genomes comprise a well-supported monophyletic clade within which the evolutionary rate is typical of SARS-CoV-2. The Alpha epidemic continued to grow despite the continued restrictions on social mixing across the UK and the imposition of new restrictions, in particular, the English national lockdown in November 2020. While these interventions succeeded in reducing the absolute number of cases, the impact of these non-pharmaceutical interventions was predominantly to drive the decline of the SARS-CoV-2 lineages that preceded Alpha. We investigate the only two sampled sequences that fall on the branch ancestral to Alpha. We find that one is likely to be a true intermediate sequence, providing information about the order of mutational events that led to Alpha. We explore alternate hypotheses that can explain how Alpha acquired a large number of mutations yet remained largely unobserved in a region of high genomic surveillance: an under-sampled geographical location, a non-human animal population, or a chronically infected individual. We conclude that the latter provides the best explanation of the observed behaviour and dynamics of the variant, although the individual need not be immunocompromised, as persistently infected immunocompetent hosts also display a higher within-host rate of evolution. Finally, we compare the ancestral branches and mutation profiles of other VOCs and find that Delta appears to be an outlier both in terms of the genomic locations of its defining mutations and a lack of the rapid evolutionary rate on its ancestral branch. As new variants, such as Omicron, continue to evolve (potentially through similar mechanisms), it remains important to investigate the origins of other variants to identify ways to potentially disrupt their evolution and emergence.

Abstract
BACKGROUND Family-based lifestyle interventions (FBLIs) are an important method for treating childhood weight problems. Despite being recognized as an effective intervention method, the optimal structure of these interventions for children's overweight and obesity has yet to be determined. Our aim was to better understand participants' (a) implementation of behaviour strategies and long-term outcomes, (b) perceptions regarding the optimal structure of FBLIs, and (c) insights into psychological concepts that may explain the success of these programs. METHODS Purposive sampling was used to recruit participants. We conducted focus groups as well as one-to-one interviews with parents (n = 53) and children (n = 50; aged 7-13, M = 9.4 yr, SD = 3.1) three months following their involvement in a 10-week, multi-component, FBLI involving education and activities relating to healthy nutrition, physical activity, and behavior modification. Using an interpretivist approach, a qualitative study design was employed to examine participant experiences. RESULTS We identified three higher-order categories: (a) participants' program experiences and perceptions (b) lifestyle changes post-program, and (c) recommendations for optimizing family-based programs. Themes identified within these categories included (a) support and structure & content, (b) diet and physical activity, and (c) in-program recommendations and post-program recommendations. CONCLUSIONS We identified several challenges that can impair lasting behavior change (e.g., physical activity participation) following involvement in a FBLI. On optimizing these programs, participants emphasized fun, interactive content, interpersonal support, appropriate educational content, and behavior change techniques. Concepts rooted in motivational theory could help address calls for greater theoretical and mechanistic insight in FBLIs. Findings may support research advancement and assist health professionals to more consistently realize the potential of these interventions.

Abstract
Although recombination is a feature of coronavirus evolution, previously detected recombinant lineages of SARS-CoV-2 have shown limited circulation thus far. Here, we present a detailed phylogenetic analysis of four SARS-CoV-2 lineages to investigate the possibility of virus recombination among them. Our analyses reveal well-supported phylogenetic differences between the Orf1ab region encoding viral non-structural proteins and the rest of the genome, including Spike (S) protein and remaining reading frames. By accounting for several deletions in NSP6, Orf3a, and S, we conclude that the B.1.628 major cluster, now designated as lineage XB, originated from a recombination event between viruses of B.1.631 and B.1.634 lineages. This scenario is supported by the spatiotemporal distribution of these lineages across the USA and Mexico during 2021, suggesting that the recombination event originated in this geographical region. This event raises important questions regarding the role and potential effects of recombination on SARS-CoV-2 evolution.

Abstract
SUMMARY gofasta comprises a set of command-line utilities for handling alignments of short assembled genomes in a genomic epidemiology context. It was developed for processing large numbers of closely related SARS-CoV-2 viral genomes and should be useful with other densely sampled pathogen genomic datasets. It provides functions to convert sam-format pairwise alignments between assembled genomes to fasta format; to annotate mutations in multiple sequence alignments, and to extract sets of sequences by genetic distance measures for use in outbreak investigations. AVAILABILITY AND IMPLEMENTATION gofasta is an open-source project distributed under the MIT license. Binaries are available at https://github.com/virus-evolution/gofasta, from Bioconda, and through the Go programming language's package management system. Source code and further documentation, including walkthroughs for common use cases, are available on the GitHub repository.

Abstract
Recombination can occur either as a result of crossover or gene conversion events. Population genetic methods for inferring the rate of recombination from patterns of linkage disequilibrium generally assume a simple model of recombination that only involves crossover events and ignore gene conversion. However, distinguishing the 2 processes is not only necessary for a complete description of recombination, but also essential for understanding the evolutionary consequences of inversions and other genomic partitions in which crossover (but not gene conversion) is reduced. We present heRho, a simple composite likelihood scheme for coestimating the rate of crossover and gene conversion from individual diploid genomes. The method is based on analytic results for the distance-dependent probability of heterozygous and homozygous states at 2 loci. We apply heRho to simulations and data from the house mouse Mus musculus castaneus, a well-studied model. Our analyses show (1) that the rates of crossover and gene conversion can be accurately coestimated at the level of individual chromosomes and (2) that previous estimates of the population scaled rate of recombination ρ=4Ner under a pure crossover model are likely biased.

Abstract
BACKGROUND Robotically performed neurointerventional surgery has the potential to reduce occupational hazards to staff, perform intervention with greater precision, and could be a viable solution for teleoperated neurointerventional procedures. OBJECTIVE To determine the indication, robotic systems used, efficacy, safety, and the degree of manual assistance required for robotically performed neurointervention. METHODS We conducted a systematic review of the literature up to, and including, articles published on April 12, 2021. Medline, PubMed, Embase, and Cochrane register databases were searched using medical subject heading terms to identify reports of robotically performed neurointervention, including diagnostic cerebral angiography and carotid artery intervention. RESULTS A total of 8 articles treating 81 patients were included. Only one case report used a robotic system for intracranial intervention, the remaining indications being cerebral angiography and carotid artery intervention. Only one study performed a comparison of robotic and manual procedures. Across all studies, the technical success rate was 96% and the clinical success rate was 100%. All cases required a degree of manual assistance. No studies had clearly defined patient selection criteria, reference standards, or index tests, preventing meaningful statistical analysis. CONCLUSIONS Given the clinical success, it is plausible that robotically performed neurointerventional procedures will eventually benefit patients and reduce occupational hazards for staff; however, there is no high-level efficacy and safety evidence to support this assertion. Limitations of current robotic systems and the challenges that must be overcome to realize the potential for remote teleoperated neurointervention require further investigation.

Abstract
Introduction Reviews suggest that family interventions including family therapy are effective for a range of disorders in youth. Family sculpting is used in different clinical settings to help young patients, their parents and siblings when words are not enough. Objectives Participants will be able to understand the clinical relevance of family sculpting: shifting from discussions about family problems to physical representations of family dynamics and how to apply in their practice. Methods There will be a brief overview of the general principle of family sculpting followed by clinical vignettes of patients combined with videos of the intervention. These examples will guide the discussion on how relevant in our clinical work this therapeutic practice may be. This variation on sculpting incorporates theater warmup exercises and therapists joining the family experience. Results Family sculpting captures an immediate picture of the family dynamics that is a therapeutic turning point for families and gives voice to the children. The clinical cases and videos will guide clinicians on how to integrate into their own practice. Conclusions This presentation will make possible integrating family sculpting into your own practice, providing an engaging alternative modality for complex cases. Disclosure No significant relationships.

Abstract
Foot-and-mouth disease is an economically devastating disease of livestock caused by foot-and-mouth disease virus (FMDV). Vaccination is the most effective control measure in place to limit the spread of the disease; however, the success of vaccination campaigns is hampered by the antigenic diversity of FMDV and the rapid rate at which new strains emerge that escape pre-existing immunity. FMDV has seven distinct serotypes, and within each serotype are multiple strains that often induce little cross-protective immunity. The diversity of FMDV is a consequence of the high error rate of the RNA-dependent RNA polymerase, accompanied by extensive recombination between genomes during co-infection. Since multiple serotypes and strains co-circulate in regions where FMDV is endemic, co-infection is common, providing the conditions for recombination, and also for other events such as trans-encapsidation in which the genome of one virus is packaged into the capsid of the co-infecting virus. Here, we demonstrate that the co-infection of cells with two FMDVs of different serotypes results in trans-encapsidation of both viral genomes. Crucially, this facilitates the infection of new cells in the presence of neutralizing antibodies that recognize the capsid that is encoded by the packaged genome.

Abstract
COG-UK Mutation Explorer (COG-UK-ME, https://sars2.cvr.gla.ac.uk/cog-uk/-last accessed date 16 March 2022) is a web resource that displays knowledge and analyses on SARS-CoV-2 virus genome mutations and variants circulating in the UK, with a focus on the observed amino acid replacements that have an antigenic role in the context of the human humoral and cellular immune response. This analysis is based on more than 2 million genome sequences (as of March 2022) for UK SARS-CoV-2 data held in the CLIMB-COVID centralised data environment. COG-UK-ME curates these data and displays analyses that are cross-referenced to experimental data collated from the primary literature. The aim is to track mutations of immunological importance that are accumulating in current variants of concern and variants of interest that could alter the neutralising activity of monoclonal antibodies (mAbs), convalescent sera, and vaccines. Changes in epitopes recognised by T cells, including those where reduced T cell binding has been demonstrated, are reported. Mutations that have been shown to confer SARS-CoV-2 resistance to antiviral drugs are also included. Using visualisation tools, COG-UK-ME also allows users to identify the emergence of variants carrying mutations that could decrease the neutralising activity of both mAbs present in therapeutic cocktails, e.g. Ronapreve. COG-UK-ME tracks changes in the frequency of combinations of mutations and brings together the curated literature on the impact of those mutations on various functional aspects of the virus and therapeutics. Given the unpredictable nature of SARS-CoV-2 as exemplified by yet another variant of concern, Omicron, continued surveillance of SARS-CoV-2 remains imperative to monitor virus evolution linked to the efficacy of therapeutics.

Abstract
OBJECTIVES In-hospital stroke is associated with poor outcomes. Reasons for delays, use of interventions, and presence of large vessel occlusion are not well characterized. MATERIALS AND METHODS A retrospective single center cohort of 97 patients with in-hospital stroke was analyzed to identify factors associated with delays from last known normal to symptom identification and to stroke team alerting. Stroke interventions and presence of large vessel occlusion were also assessed. RESULTS Strokes were predominantly on surgery services (70%), ischemic (82%), and severe (median NIHSS 16; interquartile range [IQR] 6-24). There were long delays from last known normal to symptom identification (median 5.1 hours, IQR 1.0-19.7 hours), symptom identification to stroke team alerting (median 2.1 hours, IQR 0.5-9.9 hours), and total time from last known normal to alerting (median 11.4 [IQR 2.7-34.2] hours). In univariable analysis, being on a surgical service, in an ICU, intubated, and higher NIHSS were associated with delays. In multivariable analysis only intubation was independently associated with time from last known normal to symptom identification (coefficient 20 hours, IQR 0.2 - 39.8, p=0.047). Interventions were given to 17/80 (21%) ischemic stroke patients; 3 (4%) received IV tPA and 14 (18%) underwent thrombectomy. Vascular imaging occurred in 57/80 (71%) ischemic stroke patients and 21/57 (37%) had large vessel occlusion. CONCLUSIONS Hospitalized patients with stroke experience long delays from symptom identification to stroke team alerting. Intubation was strongly associated with delay to symptom identification. Although stroke severity was high and large vessel occlusion common, many patients did not receive acute interventions.

Abstract
PURPOSE Longitudinal Integrated Clerkships (LICs) are a recognised model of curriculum design used internationally as an alternative to traditional block rotations in medical schools that have been shown to offer a multitude of educational benefits. As a relatively new development in the United Kingdom (UK), it is not yet clear whether these benefits will translate into a UK healthcare context. This article provides an early review of evaluations of UK LIC programmes. METHODS A narrative literature review of LIC programme evaluations in UK medical schools. RESULTS UK students and faculty found value in the LIC programmes with reported benefits including continuity of relationships, increased responsibility and purpose for students, a patient-centred approach and development of professional skills. However, students and GP tutors expressed initial anxieties adapting to the newness of the programme design and preparedness for exams. CONCLUSIONS UK LIC programmes appear to be offering benefits for UK medical students and faculty members including personal and professional development in line with international literature. However, the current data is limited with significant gaps that need addressing for the impacts to be fully realised.

Abstract
Volunteering has been identified as a potential mechanism for improving the psychosocial health of older adults. Utilizing a randomized controlled trial approach, the present study assessed the extent to which commencing volunteering can improve psychosocial health outcomes for older people. Fully retired Australian adults aged 60+ years (N= 445) were assessed at baseline and allocated to either the intervention or control arms of the trial. Those in the intervention condition were asked to participate in at least 60 min of formal volunteering per week for 6 months. Per-protocol analyses were conducted comparing psychosocial outcomes for those who complied with the intervention condition (n= 73) to outcomes for those who complied with the control condition (n= 112). Those who complied with the intervention condition demonstrated significant improvements in life satisfaction, purpose in life, and personal growth scores over a 12-month period relative to those in the control condition who did no volunteering. Findings provide evidence of a causal relationship between commencing volunteering and improvements in psychosocial health among older adults and indicate that encouraging participation in this activity could constitute an effective healthy aging intervention.

Abstract
Background: Non-invasive screening for atherosclerosis or asymptomatic cardiovascular disease of the coronary and carotid arteries is commonly undertaken, and research has been focussed on how results from these screenings lead to behaviour change. However, no review has focused on the effects of these results on psychological distress and health-related quality of life (HRQoL). This protocol will outline how a scoping review will be conducted to map all available evidence on psychological distress and/or HRQoL outcomes following the provision of vascular imaging results of the coronary and carotid arteries. Methods: Arksey and O’Malley’s (2005) framework subsequently enhanced by Levac et al. (2010) and Peters et al (2015, 2017) will guide the scoping review. Databases such as MEDLINE (Clarivate), APA PsychINFO, EMBASE, Social Work Abstracts, Psychology and Behavioural Sciences Collection, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) will be searched using MeSH terms such as "Coronary stenosis", "Carotid Stenosis", "Psychological Distress" and "Quality of Life" and related terms. Two investigators will screen title and abstract and all articles meeting inclusion criteria will be extracted. Data on authors, publication year, country of origin, aims/purpose, methodology, intervention, outcome measures as well as key findings that relate to the scoping review questions will be extracted for each included study. The findings will be presented using tables and thematic narrative synthesis. The scoping review will not produce a pooled estimate of the impact of vascular imaging results on psychological distress and HRQoL but will present information from the included studies related to psychological distress and HRQoL. Conclusion: The review will highlight and address gaps in knowledge and provide direction for future investigations.

Abstract
The scale of data produced during the SARS-CoV-2 pandemic has been unprecedented, with more than 13 million sequences shared publicly at the time of writing. This wealth of sequence data provides important context for interpreting local outbreaks. However, placing sequences of interest into national and international context is difficult given the size of the global dataset. Often outbreak investigations and genomic surveillance efforts require running similar analyses again and again on the latest dataset and producing reports. We developed civet (cluster investigation and virus epidemiology tool) to aid these routine analyses and facilitate virus outbreak investigation and surveillance. Civet can place sequences of interest in the local context of background diversity, resolving the query into different 'catchments' and presenting the phylogenetic results alongside metadata in an interactive, distributable report. Civet can be used on a fine scale for clinical outbreak investigation, for local surveillance and cluster discovery, and to routinely summarise the virus diversity circulating on a national level. Civet reports have helped researchers and public health bodies feedback genomic information in the appropriate context within a timeframe that is useful for public health.

Abstract
The Delta variant of concern of SARS-CoV-2 has spread globally causing large outbreaks and resurgences of COVID-19 cases 1-3 . The emergence of Delta in the UK occurred on the background of a heterogeneous landscape of immunity and relaxation of non-pharmaceutical interventions 4,5 . Here we analyse 52,992 Delta genomes from England in combination with 93,649 global genomes to reconstruct the emergence of Delta, and quantify its introduction to and regional dissemination across England, in the context of changing travel and social restrictions. Through analysis of human movement, contact tracing, and virus genomic data, we find that the focus of geographic expansion of Delta shifted from India to a more global pattern in early May 2021. In England, Delta lineages were introduced >1,000 times and spread nationally as non-pharmaceutical interventions were relaxed. We find that hotel quarantine for travellers from India reduced onward transmission from importations; however the transmission chains that later dominated the Delta wave in England had been already seeded before restrictions were introduced. In England, increasing inter-regional travel drove Delta's nationwide dissemination, with some cities receiving >2,000 observable lineage introductions from other regions. Subsequently, increased levels of local population mixing, not the number of importations, was associated with faster relative growth of Delta. Among US states, we find that regions that previously experienced large waves also had faster Delta growth rates, and a model including interactions between immunity and human behaviour could accurately predict the rise of Delta there. Delta's invasion dynamics depended on fine scale spatial heterogeneity in immunity and contact patterns and our findings will inform optimal spatial interventions to reduce transmission of current and future VOCs such as Omicron.

Abstract
Research on psychological flow is well established, although criticisms remain regarding conceptual and measurement issues associated with the construct. This scoping review maps flow-related research across scientific disciplines, examining the conceptualization, measurement instruments, and outcomes of flow between 2012 and 2019. Across 236 sources that met the review criteria, 108 different flow-related constructs were measured by 141 instruments, and 84 possible antecedents were identified. Despite the varied approaches, a common set of overarching antecedent constructs included "optimal challenge" and "high motivation," and recurring characteristics of the flow experience itself included "absorption," "effort-less control," and "intrinsic reward." Applied studies-albeit inconsistent in approach and largely correlational in nature-predominantly linked flow to "positive development" (i.e., well-being and health), "high functioning," and "further engagement." We contextualize the findings of the review relative to important work on flow that has recently emerged (following the review period)-in doing so, we hope this review offers a contemporary framework that can be used for the study of flow across scientific disciplines.
