Internet Interv 2021; 25:100400. [PMID: 34026569 PMCID: PMC8122006 DOI: 10.1016/j.invent.2021.100400] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 04/28/2021] [Accepted: 04/29/2021] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Low engagement with self-guided online programs limits the potential of these programs to provide effective and low-cost treatment of mild to moderate depression and anxiety at scale. Identifying factors that increase uptake and adherence in self-guided online programs may facilitate the development of targeted implementation strategies to increase engagement with these programs in the community. Using data from a randomized controlled trial of a self-guided online program for depression and anxiety, the aim of this study was to identify predictors of the acceptability of internet-based psychological programs, and engagement (uptake and adherence) with the online program tested in the trial. METHODS A total of 556 community members with elevated symptoms of depression or anxiety were recruited via social media into the two active conditions of a three-arm randomized controlled trial. This trial tested the effectiveness of a 7-week self-guided online program for depression and anxiety called myCompass 2, delivered with or without an Engagement-Facilitation Intervention. Predictors of uptake (accessing at least one therapeutic module of the program), adherence (modules completed), and acceptability of internet-based psychological programs (Unified Theory of Acceptance and Use of Technology, UTAUT scale) were examined, including demographics, mental health status, help-seeking attitudes, stigma, acceptability of internet programs, and personality factors. RESULTS Logistic regression demonstrated that higher levels of conscientiousness (OR = 1.06, p = .026, 95% CI =1.01-1.12), and acceptability of internet-based psychological programs (OR = 1.09, p = .005, 95% CI =1.03-1.16) predicted greater uptake, and that failing to complete a module was predicted by lower levels of acceptability (OR = 0.88, p = .027, 95% CI =0.78-0.99). Linear regression showed that higher levels of agreeableness (t = 4.66, p < .001), lower levels of stigma (t = -2.28, p = .023) and more positive help-seeking attitudes (t = 2.05, p = .041) predicted higher acceptability attitudes. DISCUSSION Acceptability of internet-based psychological programs was identified as a factor that increased both uptake and adherence to the myCompass 2 program. Efforts to increase the acceptability of these programs may improve engagement with these programs in the community. It may also be useful to consider personality traits and clinical profiles when considering the appropriate audience for self-guided internet interventions.

Abstract
As part of a broader project to create a comprehensive self-report measure for the Hierarchical Taxonomy of Psychopathology consortium, we developed preliminary scales to assess internalizing symptoms. The item pool was created in four steps: (a) clarifying the range of content to be assessed, (b) identifying target constructs to guide item writing, (c) developing formal definitions for each construct, and (d) writing multiple items for each construct. This yielded 430 items assessing 57 target constructs. Responses from a heterogeneous scale development sample (N = 1,870) were subjected to item-level factor analyses based on polychoric correlations. This resulted in 39 scales representing a total of 213 items. The psychometric properties of these scales replicated well across the development sample and an independent validation sample (N = 496 adults). Internal consistency analyses established that most scales assess relatively narrow forms of psychopathology. Structural analyses demonstrated the presence of a strong general factor. Additional analyses of the 35 nonsexual dysfunction scales revealed a replicable four-factor structure with dimensions we labeled Distress, Fear, Body Dysmorphia, and Mania. A final set of analyses established that the internalizing scales varied widely-and consistently-in the strength of their associations with neuroticism and extraversion.

Abstract
BACKGROUND Neurocognitive deficits are common among youth with mental disorders, and patterns of aberrant brain function generally cross diagnostic boundaries. This study investigated associations between functional neurocircuitry and broad transdiagnostic psychopathology dimensions in the critical preadolescent period when psychopathology is emerging. METHODS Participants were 9- to 10-year-olds from the Adolescent Brain Cognitive Development Study. Factor scores of general psychopathology, externalizing, internalizing, and thought disorder dimensions were calculated from a higher-order model of psychopathology using confirmatory factor analysis (N = 11,721) and entered as explanatory variables into linear mixed models to examine associations with resting-state functional connectivity (n = 9074) and neural activation during the emotional n-back task (n = 6146) when covarying for sex, race/ethnicity, parental education, and cognitive function. RESULTS All dimensions of psychopathology were commonly characterized by hypoconnectivity within the dorsal attention and retrosplenial-temporal networks, hyperconnectivity between the frontoparietal and ventral attention networks and between the dorsal attention network and amygdala, and hypoactivation of the caudal middle frontal gyrus. Externalizing pathology was uniquely associated with hyperconnectivity between the salience and ventral attention networks and hyperactivation of the cingulate and striatum. Internalizing pathology was uniquely characterized by hypoconnectivity between the default mode and cingulo-opercular networks. Connectivity between the cingulo-opercular network and putamen was uniquely higher for internalizing pathology and lower for thought disorder pathology. CONCLUSIONS These findings provide novel evidence that broad psychopathology dimensions are characterized by common and dissociable patterns, particularly for externalizing pathology, of functional connectivity and task-evoked activation throughout neurocognitive networks in preadolescence.

Abstract
INTRODUCTION There is a substantial literature finding that moderate alcohol consumption is protective against certain health conditions. However, more recent research has highlighted the possibility that these findings are methodological artefacts, caused by confounding and other biases. While modern analytical and study design approaches can mitigate confounding and thus enhance causal inference in observational studies, they are not routinely applied in research assessing the relationship between alcohol use and long-term health outcomes. The purpose of this systematic review is to identify observational studies that employ these analytical/design-based approaches in assessing whether relationships between alcohol consumption and health outcomes are non-linear. This review seeks to evaluate, on a per-outcome basis, what these studies find the strength and form of the relationship between alcohol consumption and health to be. METHODS AND ANALYSIS Electronic databases (MEDLINE, PsycINFO, Embase and SCOPUS) were searched in May 2020. Study selection will comply with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles will be screened against eligibility criteria intended to capture studies using observational data to assess the relationship between varying levels of alcohol exposure and any long-term health outcome (actual or surrogate), and that have employed at least one of the prespecified approaches to enhancing causal inference. Risk of bias of included articles will be assessed using study design-specific tools. A narrative synthesis of the results is planned. ETHICS AND DISSEMINATION Formal ethics approval is not required given there will be no primary data collection. The results of the study will be disseminated through published manuscripts, conferences and seminar presentations. PROSPERO REGISTRATION NUMBER CRD42020185861.

Abstract
Much of our knowledge about the relationships among domains of psychopathology is built on the diagnostic categories described in the Diagnostic and Statistical Manual of Mental Disorders (DSM), with relatively little research examining the symptom-level structure of psychopathology. The aim of this study was to delineate a detailed hierarchical model of psychopathology-from individual symptoms up to a general factor of psychopathology-allowing both higher- and lower-order dimensions to depart from the structure of the DSM. We explored the hierarchical structure of hundreds of symptoms spanning 18 DSM disorders, in two large samples-one from the general population in Australia (n = 3175), and the other a treatment-seeking clinical sample from the USA (n = 1775). There was marked convergence between the two samples, offering new perspectives on higher-order dimensions of psychopathology. We also found several noteworthy departures from the structure of the DSM in the symptom-level data.

Abstract
Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical. When the discreteness versus continuity of psychopathology is treated as a research question, as opposed to being decided as a matter of tradition, the evidence clearly supports the hypothesis of continuity. In addition, a related body of literature shows how psychopathology dimensions can be arranged in a hierarchy, ranging from very broad "spectrum level" dimensions, to specific and narrow clusters of symptoms. In this way, a quantitative approach solves the "problem of comorbidity" by explicitly modeling patterns of co-occurrence among signs and symptoms within a detailed and variegated hierarchy of dimensional concepts with direct clinical utility. Indeed, extensive evidence pertaining to the dimensional and hierarchical structure of psychopathology has led to the formation of the Hierarchical Taxonomy of Psychopathology (HiTOP) Consortium. This is a group of 70 investigators working together to study empirical classification of psychopathology. In this paper, we describe the aims and current foci of the HiTOP Consortium. These aims pertain to continued research on the empirical organization of psychopathology; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic; and the development of novel and comprehensive models and corresponding assessment instruments for psychopathology constructs derived from an empirical approach.

Abstract
A relationship between alcohol use and aggression is well-established; however, less is known about how these factors develop and influence each other over time. This study examined the immediate and delayed effects of alcohol use on aggression during adolescence. Alcohol use and aggression were measured in a subset of students (n = 1560) from the Climate and Preventure study, Australia. Participants completed self-report surveys across five assessments (ages 13, 13.5, 14, 15 and 16). In a two-stage analysis, parallel and auto-regressive latent growth curve models were applied to investigate person-specific trajectories (or between-person effects) of alcohol use and aggression and identify the time-varying impact (or within-person effects) of alcohol use on aggression. Average alcohol consumption increased between ages 13 and 16, while average aggression levels decreased over time. Overall growth in alcohol use was positively related to heightened aggression at age 16, and vice versa. Spikes (time-varying increases) in alcohol use were linked to corresponding increases in aggression at each time point. There was evidence of a prospective effect where aggression was associated with hazardous alcohol use a year later, but no evidence that alcohol use was associated with subsequent aggression. Change in hazardous alcohol consumption and aggression beginning early in adolescence are interrelated and are predictive of one another at age 16. The time-varying effects of alcohol on aggression appear to be immediate rather than delayed; however, there is evidence for a prospective relationship where aggression influences later alcohol use. Implications for the timing and nature of novel harm reduction intervention approaches for young people are discussed.

Abstract
IMPORTANCE There is widespread interest in associations between maternal perinatal depression and anxiety and offspring development; however, to date, there has been no systematic, meta-analytic review on the long-term developmental outcomes spanning infancy through adolescence. OBJECTIVE To provide a comprehensive systematic review and meta-analysis of the extant literature on associations between maternal perinatal depression and anxiety and social-emotional, cognitive, language, motor, and adaptability outcomes in offspring during the first 18 years of life. DATA SOURCES Six databases were searched (CINAHL Complete, Cochrane Library, Embase, Informit, MEDLINE Complete, and PsycInfo) for all extant studies reporting associations between perinatal maternal mental health problems and offspring development to March 1, 2020. STUDY SELECTION Studies were included if they were published in English; had a human sample, quantitative data, a longitudinal design, and measures of perinatal depression and/or anxiety and social-emotional, cognitive, language, motor, and/or adaptability development in offspring; and investigated an association between perinatal depression or anxiety and childhood development. DATA EXTRACTION AND SYNTHESIS Of 27 212 articles identified, 191 were eligible for meta-analysis. Data were extracted by multiple independent observers and pooled using a fixed- or a random-effects model. A series of meta-regressions were also conducted. Data were analyzed from January 1, 2019, to March 15, 2020. MAIN OUTCOMES AND MEASURES Primary outcomes included social-emotional, cognitive, language, motor, and adaptability development in offspring during the first 18 years of life. RESULTS After screening, 191 unique studies were eligible for meta-analysis, with a combined sample of 195 751 unique mother-child dyads. Maternal perinatal depression and anxiety were associated with poorer offspring social-emotional (antenatal period, r = 0.21 [95% CI, 0.16-0.27]; postnatal period, r = 0.24 [95% CI, 0.19-0.28]), cognitive (antenatal period, r = -0.12 [95% CI, -0.19 to -0.05]; postnatal period, r = -0.25 [95% CI, -0.39 to -0.09]), language (antenatal period, r = -0.11 [95% CI, -0.20 to 0.02]; postnatal period, r = -0.22 [95% CI, -0.40 to 0.03]), motor (antenatal period, r = -0.07 [95% CI, -0.18 to 0.03]; postnatal period, r = -0.07 [95% CI, -0.16 to 0.03]), and adaptive behavior (antenatal period, r = -0.26 [95% CI, -0.39 to -0.12]) development. Findings extended beyond infancy, into childhood and adolescence. Meta-regressions confirmed the robustness of the results. CONCLUSIONS AND RELEVANCE Evidence suggests that perinatal depression and anxiety in mothers are adversely associated with offspring development and therefore are important targets for prevention and early intervention to support mothers transitioning into parenthood and the health and well-being of next-generation offspring.

Abstract
Background Self-guided web-based mental health programs are effective in treating and preventing mental health problems. However, current engagement with these programs in the community is suboptimal, and there is limited evidence indicating how to increase the use of existing evidence-based programs. Objective This study aims to investigate the views of people with lived experience of depression and anxiety on factors influencing their engagement with self-guided web-based mental health (e–mental health) programs and to use these perspectives to develop an engagement-facilitation intervention (EFI) to increase engagement (defined as both uptake and adherence) with these programs. Methods A total of 24 community members (female=21; male=3) with lived experience of depression and anxiety or depression or anxiety alone participated in 1 of 4 focus groups discussing the factors influencing their engagement with self-guided e–mental health programs and the appearance, delivery mode, and functionality of content for the proposed EFI. A subsequent evaluation survey of the focus group participants (n=14) was conducted to evaluate the resultant draft EFI. Data were thematically analyzed using both inductive and deductive qualitative methods. Results Participants suggested that the critical component of an EFI was information that would challenge personal barriers to engagement, including receiving personalized symptom feedback, information regarding the program’s content or effectiveness and data security, and normalization of using e–mental health programs (eg, testimonials). Reminders, rewards, feedback about progress, and coaching were all mentioned as facilitating adherence. Conclusions EFIs have the potential to improve community uptake of e–mental health programs. They should focus on providing information on the content and effectiveness of e–mental health programs and normalizing their use. Given that the sample comprised predominantly young females, this study may not be generalizable to other population groups. There is a strong value in involving people with a lived experience in the design and development of EFIs to maximize their effectiveness.

Abstract
Objective: Estimates of the extent of treatment need (defined by the presence of a
diagnosis for which there is an effective treatment available) and treatment
demand (defined as treatment seeking) are essential parts of effective
treatment planning, service provision, and treatment funding. This article
reviews the existing literature on approaches to estimating need and demand
and the use of models to inform such estimation, and then considers the
implications for health planners. Method: A thematic review of the literature was undertaken, with a focus on covering
the key concepts and research methods that have been used to date. Results: Both need and demand are important estimates in planning for services but
contain many difficulties in moving from the theory of measurement to the
practicalities of establishing these figures. Furthermore, the simple
quantum of need or demand is limited in its usefulness unless it is matched
with consideration of different treatment types and their relative
intensity, and/or explored as a function of geography and subpopulation.
Modeling can assist with establishing more fine-tuned planning estimates,
and is able to take into account both client severity and the various
treatment types that might be available. Conclusions: Moving from relatively simplistic estimates of need and demand for treatment,
this review has shown that although such estimation can inform national or
subnational treatment planning, more sophisticated models are required for
alcohol and other drug treatment planning. These can help health planners to
determine the appropriate amount and mix of treatments for substance use
disorders. Objectif : L’estimation de l’ampleur du besoin de traitement, défini
par la présence d’un diagnostic pour lequel un traitement
efficace est disponible, et la demande de traitement, définie par la
recherche de traitement, sont des éléments essentiels à une
planification efficace du traitement, à la prestation de service et
à son financement. Cet article passe en revue la littérature
existante sur les approches pour estimer le besoin et la demande ainsi que
l’utilisation de modèles pour documenter une telle estimation,
puis considère les implications pour les planificateurs des services de
santé. Méthode : Une revue thématique de la littérature a été entreprise
en mettant l’accent sur les concepts clés et les méthodes
de recherche qui ont été utilisées à ce jour. Résultats : Les estimations des besoins et de la demande sont toutes deux importantes
dans la planification des services, mais constituent des défis
importants lors du passage de la théorie de la mesure aux aspects plus
pratiques de production de ces estimations. Par ailleurs, la simple
estimation d’un nombre lié au besoin ou à la demande est
limitée, à moins qu’elle ne soit appariée avec
différents types de traitement et leur intensité respective, ou
explorée avec d’autres facteurs géographiques et de
sous-population. La modélisation aide à produire des estimations
de planification plus précises et permet de prendre en compte à la
fois la sévérité des problèmes du client et les types de
traitement qui pourraient être disponibles. Conclusion: En partant d’estimations relativement simplistes des besoins et de la
demande de traitement, cette revue a montré que si ce genre
d’estimation peut éclairer la planification des traitements
à l’échelle nationale ou régionale, d’autres
modèles plus sophistiqués sont nécessaires pour la
planification des traitements des problèmes liés à
l’usage d’alcool et des autres drogues. Ceux-ci peuvent aider
les planificateurs des services de santé à déterminer la
quantité et la combinaison appropriées de traitement pour les
troubles liés à l’utilisation de substances. Objetivo: Las estimaciones de la magnitud de las necesidades de tratamiento, que se
define por la presencia de un diagnóstico para el cual existe un
tratamiento efectivo disponible, y la demanda de tratamiento, definida como
la búsqueda de tratamiento, son parte esencial de la planificación
de un tratamiento eficaz, la prestación de servicios y la
financiación del tratamiento. Este artículo revisa la literatura
existente sobre enfoques para estimar la necesidad y la demanda y el uso de
modelos para informar a dicha estimación, y luego considera las
implicaciones para los planificadores de salud. Método: Se realizó una revisión temática de la literatura, con un
enfoque en cubrir los conceptos clave y los métodos de
investigación que se han empleado hasta la fecha. Resultados: Tanto la necesidad como la demanda son estimaciones importantes en la
planificación de los servicios, pero contienen muchas dificultades para
pasar de la teoría de la medición a los aspectos prácticos de
establecer estas cifras. Además, el simple quantum de necesidad o
demanda es limitado en su utilidad a menos que se corresponda con la
consideración de diferentes tipos de tratamiento y su intensidad
relativa, y / o explorado como una función de la geografía y la
subpoblación. El modelado puede ayudar a establecer estimaciones de
planificación más precisas, y puede tener en cuenta tanto la
gravedad del cliente como los diversos tipos de tratamiento que podrían
estar disponibles. Conclusiones: Pasando de estimaciones relativamente simplistas de la necesidad y demanda de
tratamiento, esta revisión ha demostrado que, si bien dicha
estimación puede informar la planificación del tratamiento
nacional o subnacional, se requieren modelos más sofisticados para la
planificación del tratamiento del alcohol y otras drogas. Estos pueden
ayudar a los planificadores de salud a determinar la cantidad apropiada y la
combinación de tratamientos para los trastornos por uso de

Abstract
Chronic diseases are the leading cause of disability and mortality globally. In Australia, females are at heightened risk. This research explored the prevalence, patterns, and correlates of six key risk behaviors (physical inactivity, poor diet, recreational screen time, inadequate sleep, alcohol use, and smoking) among adolescent females and whether knowledge of health guidelines was associated with adherence. Adolescent females completed an anonymous online questionnaire (N = 687; Mage = 13.82). Logistic regression assessed the association between knowledge and adherence. A Latent Class Analysis (LCA) and three-step procedure identified risk behavior clusters and their correlates. Despite positive health self-ratings (77% good/very good), most participants reported insufficient moderate-to-vigorous physical activity (MVPA; 89%), vegetable intake (89%), and excessive screen time (63%). Knowledge of guidelines was associated with adherence for MVPA, vegetable intake, sleep, and alcohol abstinence. Three classes emerged: "moderate risk" (76%), "relatively active, healthy eaters" (19%), and "excessive screen users" (5%). These risk-behavior clusters were associated with perceived value of academic achievement and physical wellbeing. Adolescent females commonly perceive they are in good health, despite engaging in unhealthy behaviors. Public health interventions should utilize effective behavior change strategies, adopt a multiple health behavior change approach (MHBC), and be tailored to specific risk profiles and values among females.

Abstract
BACKGROUND Recent studies suggest that young adult participation in, and volume of, alcohol consumption has decreased. However, the evidence on trends in harmful alcohol consumption in this age group is limited. The current paper aims to examine changes over time in harmful alcohol consumption using a robust, widely employed measure. METHODS The literature was systematically searched for articles reporting on Alcohol Use Disorders Identification Test (AUDIT) scores in young adults aged 18-24 years. The key data extracted were year of measurement and mean AUDIT score (proportion above clinical cut-off was not relevant for these analyses). Cross-temporal meta-analysis was applied to the extracted data. RESULTS A decrease was found in young adults' AUDIT scores measured between 1989 and 2015 (b=-0.13, β=-0.38, p = 0.015, 95 % CI=-0.24, -0.03), representing a 0.63 standard deviation change over this period. Variance did not change over this time, suggesting scores decreased equally over the distribution. CONCLUSIONS Results indicate that harmful alcohol consumption in young adults may have declined between 1989 and 2015. Despite the continued problems posed by dependence and short and long-term harms, these promising findings offer hope that the considerable alcohol-related disease burden in this age group may be reduced. Ongoing data collection is required to evaluate whether these declines in young adulthood persist into later life, and future research should explore the reasons for declining harmful alcohol consumption in young adults.

Abstract
OBJECTIVES The current study aimed to investigate the psychometric properties of the DSM-5 dimensional severity scales for social anxiety disorder (SAD) and panic disorder (PD) using a past 30 day timeframe. METHODS Data were from a sample of 1,052 Australian community dwelling adults (aged 18 years or older) recruited using online advertisements. Respondents completed the DSM-5 severity scales for SAD and PD as well as a range of additional widely used self-administered scales for SAD and PD in the past 30 days prior to the survey. RESULTS Both scales exhibited high internal consistency (alpha>=0.94) and a strong general factor that justified unidimensional item response analysis (OmegaH=0.96). There was no evidence of significant local dependence amongst item pairs after accounting for the single factor. Similarly, there was no evidence for meaningful differential item functioning of the scales across sex, age, education level, and residential location. There was high convergent validity (0.71 - 0.85) amongst conceptually related scale and moderate to high correlations (0.54 - 0.80) between conceptually unrelated scales. CONCLUSIONS These findings provide support for the use of past month versions of the DSM-5 severity scales for SAD and PD by researchers and clinicians to inform and supplement diagnostic decisions.

Abstract
Background Mental and substance use disorders are among the leading causes of burden of disease worldwide, with risk of onset peaking between the ages of 13 and 24 years. Comorbidity is also common among young people and complicates research, diagnosis and assessment, and clinical decision making. There is increasing support for empirically derived models of psychopathology that overcome issues of comorbidity and provide a transdiagnostic framework for investigating the specificity and generality of risk and protective factors for psychopathology. Objective This systematic review aims to identify transdiagnostic risk and protective factors for psychopathology in young people by synthesizing and evaluating findings from research investigating empirically based models of psychopathology. Methods Searches will be conducted in Medline, EMBASE, and PsycINFO databases. Reference lists of selected articles will also be hand searched for other relevant publications. All studies will be screened against eligibility criteria designed to identify studies that examined empirical models of psychopathology in relation to risk and/or protective factors in young people with a mean age between 10 and 24 years. Study quality will be assessed using the Joanna Briggs Institute Critical Appraisal Checklists for Cohort Studies and Analytical Cross-Sectional Studies. Findings will be summarized in a narrative synthesis, and a meta-analysis will be conducted if sufficient data are available. Results This review is ongoing. At the time of submission, full-text screening was completed, and hand searching of selected articles was underway. Results are expected to be completed by the end of 2020. Conclusions This protocol is for a systematic review of evidence for transdiagnostic risk and protective factors associated with empirically based models of psychopathology in young people. To our knowledge, the critical synthesis of this evidence will be the first to date and will provide a better understanding of the factors that contribute to the onset and maintenance of psychopathology in young people. Insights drawn from the review will provide critical new knowledge to improve the targeting of interventions to prevent or reduce mental health problems. Trial Registration This systematic review is registered with PROSPERO (CRD42020161368) and is available via Open Science Framework.

Abstract
INTRODUCTION Lifestyle risk behaviours, including alcohol use, smoking, poor diet, physical inactivity, poor sleep (duration and/or quality) and sedentary recreational screen time ('the Big 6'), are strong determinants of chronic disease. These behaviours often emerge during adolescence and co-occur. School-based interventions have the potential to address risk factors prior to the onset of disease, yet few eHealth school-based interventions target multiple behaviours concurrently. This paper describes the protocol of the Health4Life Initiative, an eHealth school-based intervention that concurrently addresses the Big 6 risk behaviours among secondary school students. METHODS AND ANALYSIS A multisite cluster randomised controlled trial will be conducted among year 7 students (11-13 years old) from 72 Australian schools. Stratified block randomisation will be used to assign schools to either the Health4Life intervention or an active control (health education as usual). Health4Life consists of (1) six web-based cartoon modules and accompanying activities delivered during health education (once per week for 6 weeks), and a smartphone application (universal prevention), and (2) additional app content, for students engaging in two or more risk behaviours when they are in years 8 and 9 (selective prevention). Students will complete online self-report questionnaires at baseline, post intervention, and 12, 24 and 36 months after baseline. Primary outcomes are consumption of sugar-sweetened beverages, moderate-to-vigorous physical activity, sleep duration, sedentary recreational screen time and uptake of alcohol and tobacco use. ETHICS AND DISSEMINATION This study has been approved by the University of Sydney (2018/882), NSW Department of Education (SERAP no. 2019006), University of Queensland (2019000037), Curtin University (HRE2019-0083) and relevant Catholic school committees. Results will be presented to schools and findings disseminated via peer-reviewed journals and scientific conferences. This will be the first evaluation of an eHealth intervention, spanning both universal and selective prevention, to simultaneously target six key lifestyle risk factors among adolescents.

Abstract
OBJECTIVE Globally, the prevalence of hazardous drinking peaks in young adulthood, and there is mixed evidence on whether internalising symptoms and executive functioning deficits are associated with this increased risk. This study tested whether internalising symptoms in interaction with executive functioning deficits are associated with high alcohol use disorder symptoms in emerging adulthood, via drinking motives to cope with negative affect and alcohol consumption. METHOD An Australian sample of 155 young adults aged 17 to 24 years (M = 20.97, SD = 2.40) provided self-report data on internalising symptom severity and alcohol-related outcomes (n = 155), and neuropsychological data measuring executive functioning (n = 104). Confirmatory factor analyses were conducted to identify two latent variables representing internalising symptoms and executive functions. A series of latent moderated structural equation models and a latent mediated moderation structural equation model examined the inter-relations between internalising symptoms, executive functions and alcohol measures. RESULTS High levels of internalising symptoms in interaction with executive functioning deficits were associated with strong drinking motives to cope with negative affect, high past month alcohol consumption and greater alcohol use disorder symptoms. Drinking motives to cope with negative affect and alcohol consumption mediated the relationship between the internalising symptoms and executive functioning latent interaction term with alcohol use disorder symptoms. CONCLUSIONS This research highlights greater executive functioning resources are associated with low desires to drink hazardous amounts of alcohol as a maladaptive way to cope with negative feelings among young people. It therefore may be useful to target executive functioning ability alongside internalising symptomology in alcohol prevention and intervention initiatives.

Abstract
BACKGROUND Six core behavioural risk factors (poor diet, physical activity, sedentary behaviour, alcohol misuse, smoking and unhealthy sleep patterns) have been identified as strong determinants of chronic disease, such as cardiovascular disease, diabetes and cancers. Smartphones have the potential to provide a real-time, pervasive, unobtrusive and cost-effective way to measure health behaviours and deliver instant feedback to users. Despite this, validity of using smartphones to measure these six key behaviours is largely unknown. The proposed systematic review aims to address this gap by identifying existing smartphone-based approaches to measure these health behaviours and critically appraising, comparing and summarizing the quality of their measurement properties. METHODS A systematic search of the Ovid MEDLINE, Embase (Elsevier), Cochrane Library (Wiley), PsychINFO (EBSCOhost), CINAHL (EBSCOHost), Web of Science (Clarivate), SPORTDiscus (EBSCOhost) and IEEE Xplore Digital Library databases will be conducted from January 2007 to March 2020. Eligible studies will be those written in English that measure at least one of the six health behaviours of interest via a smartphone and report on at least one measurement property. The primary outcomes will be validity, reliability and/or responsiveness of these measurement approaches. A secondary outcome will be the feasibility (e.g. user burden, usability and cost) of identified approaches. No restrictions will be placed on the participant population or study design. Two reviewers will independently screen studies for eligibility, extract data and assess the risk of bias. The study methodological quality (or bias) will be appraised using an appropriate tool. Our results will be described in a narrative synthesis. If feasible, random effects meta-analysis will be conducted where appropriate. DISCUSSION The results from this review will provide important information about the types of smartphone-based approaches currently available to measure the core behavioural risk factors for chronic disease and the quality of their measurement properties. It will allow recommendations on the most suitable and effective measures of these lifestyle behaviours using smartphones. Valid and reliable measurement of these behaviours and risk factor opens the door to targeted and real-time delivery of health behaviour interventions, providing unprecedented opportunities to offset the trajectory toward chronic disease.

Abstract
The Hierarchical Taxonomy of Psychopathology (HiTOP) is a scientific effort to address shortcomings of traditional mental disorder diagnoses, which suffer from arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, heterogeneity within disorders, and diagnostic instability. This paper synthesizes evidence on the validity and utility of the thought disorder and detachment spectra of HiTOP. These spectra are composed of symptoms and maladaptive traits currently subsumed within schizophrenia, other psychotic disorders, and schizotypal, paranoid and schizoid personality disorders. Thought disorder ranges from normal reality testing, to maladaptive trait psychoticism, to hallucinations and delusions. Detachment ranges from introversion, to maladaptive detachment, to blunted affect and avolition. Extensive evidence supports the validity of thought disorder and detachment spectra, as each spectrum reflects common genetics, environmental risk factors, childhood antecedents, cognitive abnormalities, neural alterations, biomarkers, and treatment response. Some of these characteristics are specific to one spectrum and others are shared, suggesting the existence of an overarching psychosis superspectrum. Further research is needed to extend this model, such as clarifying whether mania and dissociation belong to thought disorder, and explicating processes that drive development of the spectra and their subdimensions. Compared to traditional diagnoses, the thought disorder and detachment spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and higher acceptability to clinicians. Validated measures are available to implement the system in practice. The more informative, reliable and valid characterization of psychosis-related psychopathology offered by HiTOP can make diagnosis more useful for research and clinical care.

Abstract
BACKGROUND There are few very brief measures that accurately identify multiple common mental disorders. AIMS The aim of this study was to develop and assess the psychometric properties of a new composite measure to screen for five common mental disorders. METHOD Two cross-sectional psychometric surveys were used to develop (n = 3175) and validate (n = 3620) the new measure, the Rapid Measurement Toolkit-20 (RMT20) against diagnostic criteria. The RMT20 was tested against a DSM-5 clinical checklist for major depression, generalised anxiety disorder, panic disorder, social anxiety disorder and post-traumatic stress disorder, with comparison with two measures of general psychological distress: the Kessler-10 and Distress Questionnaire-5. RESULTS The area under the curve for the RMT20 was significantly greater than for the distress measures, ranging from 0.86 to 0.92 across the five disorders. Sensitivity and specificity at prescribed cut-points were excellent, with sensitivity ranging from 0.85 to 0.93 and specificity ranging from 0.73 to 0.83 across the five disorders. CONCLUSIONS The RMT20 outperformed two established scales assessing general psychological distress, is free to use and has low respondent burden. The measure is well-suited to clinical screening, internet-based screening and large-scale epidemiological surveys.

Abstract
OBJECTIVE The aim of the current study was to use a 23-item bank of self-reported symptoms of suicidal thoughts and behaviors to develop new brief measures of suicide risk using data-driven methods. Collectively referred to as the Rapid Measurement Toolkit for Suicidality (RMTS), the new brief static and adaptive measures would allow more efficient screening for suicide risk in clinical and research settings. METHOD Data for the current study consist of 3,175 Australian adults who form the development sample and 3,755 Australian adults who form the validation sample. Both samples were independently recruited online using Facebook advertisements. Item response theory (IRT) was applied to the 23-item suicide item bank to develop a brief static dimensional measure and to simulate various computerized adaptive algorithms. RESULTS A 5-item brief static dimensional screener was developed, which performed as well as the commonly used Suicidal Behaviors Questionnaire-Revised (SBQ-R), with marginally greater sensitivity and more information across the continuum of suicidality. An adaptive screener required a mean of 6.2 items and correlated 0.98 with the full item bank. CONCLUSIONS The RMTS provides reliable and valid brief static and adaptive screeners for the measurement of suicide risk in community, research, and clinical settings.

Abstract
This study aimed to examine associations between maladaptive personality traits and psychopathology from the perspective of the hierarchical taxonomy of psychopathology (HiTOP). We tested hierarchical structural models to further validate a portion of the structural components of HiTOP. We also tested a priori personality and psychopathology associations with three levels of the HiTOP hierarchy: general psychopathology, spectra and syndromes/disorders. We used a large sample from the general Australian population who completed a large set of personality and psychopathology inventories online. Confirmatory factor analyses indicated that internalizing, externalizing and thought dysfunction spectra emerged structurally, as expected per HiTOP, but also revealed that obsessive-compulsive disorder loaded on both internalizing and thought dysfunction and attention deficit hyperactivity disorder on both externalizing and internalizing. Furthermore, results indicated that almost all personality and psychopathology hypotheses were supported, although trait antagonism did not predict externalizing to the degree initially expected. Implications for personality and psychopathology are discussed. © 2019 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE To investigate the contribution of nine mental/substance use disorders to fatigue and sleep disturbance. METHODS 3620 Australians aged 18 years or older recruited from the general community via Facebook during January-February 2016 completed an online survey assessing demographic characteristics, diagnosed medical conditions and nine mental disorders. Outcome measures were Patient Reported Outcomes Measurement Information System (PROMIS®) fatigue and PROMIS sleep disturbance. RESULTS Overall, 56% of the sample met criteria for at least one mental disorder. Linear regression models of sleep disturbance revealed all mental disorders except obsessive compulsive disorder (β = 0.038) had independent associations with sleep disturbance, with generalised anxiety disorder (GAD) (β = 0.173), major depressive disorder (MDD) (β = 0.117) and post-traumatic stress disorder (PTSD) (β = 0.111) making the greatest contribution. Inclusion of fatigue in the model attenuated the effects of panic disorder, MDD and attention-deficit hyperactive disorder (ADHD) to non-significance. For the outcome of fatigue, GAD (β = 0.223), MDD (β = 0.176) and PTSD (β = 0.147) made the greatest contributions, although all disorders had significant independent relationships. After adjusting for sleep disturbance, all mental disorders continued to make a significant contribution except for alcohol use disorder and substance use disorder. CONCLUSION Sleep disturbance and fatigue have independent associations with many mental disorders after correcting for comorbidity and known confounds. The disorders providing the greatest contribution to sleep disturbance and fatigue were GAD and MDD. Sleep disturbance and fatigue may be appropriate transdiagnostic targets for improving symptoms and global functioning for people with mental disorders.
