Joint developmental trajectories of internalizing and externalizing problems from mid-childhood to late adolescence and childhood risk factors: Findings from a prospective pre-birth cohort.

There is limited evidence on heterogenous co-developmental trajectories of internalizing (INT) and externalizing (EXT) problems from childhood to adolescence and predictors of these joint trajectories. We utilized longitudinal data from Raine Study participants (n = 2393) to identify these joint trajectories from 5 to 17 years using parallel-process latent class growth analysis and analyze childhood individual and family risk factors predicting these joint trajectories using multinomial logistic regression. Five trajectory classes were identified: Low-problems (Low-INT/Low-EXT, 29%), Moderate Externalizing (Moderate-EXT/Low-INT, 26.5%), Primary Internalizing (Moderate High-INT/Low-EXT, 17.5%), Co-occurring (High-INT/High-EXT, 17%), High Co-occurring (Very High-EXT/High-INT, 10%). Children classified in Co-occurring and High Co-occurring trajectories (27% of the sample) exhibited clinically meaningful co-occurring problem behaviors and experienced more adverse childhood risk-factors than other three trajectories. Compared with Low-problems: parental marital problems, low family income, and absent father predicted Co-occurring and High Co-occurring trajectories; maternal mental health problems commonly predicted Primary Internalizing, Co-occurring, and High Co-occurring trajectories; male sex and parental tobacco-smoking uniquely predicted High Co-occurring membership; other substance smoking uniquely predicted Co-occurring membership; speech difficulty uniquely predicted Primary Internalizing membership; child's temper-tantrums predicted all four trajectories, with increased odds ratios for High Co-occurring (OR = 8.95) and Co-occurring (OR = 6.07). Finding two co-occurring trajectories emphasizes the importance of early childhood interventions addressing comorbidity.

Exploring human papillomavirus vaccination decision making through mother and adolescent dyad interviews.

INTRODUCTION: The purpose of our research was to explore how parents and their adolescent children make decisions about the human papillomavirus (HPV) vaccine, and to inform future interventions that aim to facilitate inclusive decision-making processes. METHOD: Purposive and snowball sampling strategies targeted parents and their adolescent children (ages = 11-13) in a large city in Australia. We conducted separate and joint semistructured interviews in 2013 with six mother-adolescent dyads (50% female adolescents and 50% male). Interviews were analyzed using a grounded theory approach. RESULTS: Factors that both facilitate and impede decision making emerged, including: background knowledge, values, historical experiences, parenting style, and opinion weights. DISCUSSION: New interventions, strategies, and tools that are informed by these decision-making factors can be used to aid productive, mutual decision making between parents and adolescents and support adolescent autonomy and self-sufficiency in health decision making.

Immunogenicity, safety, usability and acceptability of microarray patches for vaccination: a systematic review and meta-analysis.

BACKGROUND: Microarray patches (MAPs) deliver vaccines to the epidermis and the upper dermis, where abundant immune cells reside. There are several potential benefits to using MAPs, including reduced sharps risk, thermostability, no need for reconstitution, tolerability and self-administration. We aimed to explore and evaluate the immunogenicity, safety, usability and acceptability of MAPs for vaccination. METHODS: We searched CINAHL, Cochrane Library, Ovid Embase, Ovid MEDLINE and Web of Science from inception to January 2023. Eligibility criteria included all research studies in any language, which examined microarrays or microneedles intended or used for vaccination and explored immunogenicity, safety, usability or acceptability in their findings. Two reviewers conducted title and abstract screening, full-text reviewing and data extraction. RESULTS: Twenty-two studies were included (quantitative=15, qualitative=2 and mixed methods=5). The risk of bias was mostly low, with two studies at high risk of bias. Four clinical trials were included, three using influenza antigens and one with Japanese encephalitis delivered by MAP. A meta-analysis indicated similar or higher immunogenicity in influenza MAPs compared with needle and syringe (N&S) (standardised mean difference=10.80, 95% CI: 3.51 to 18.08, p<0.00001). There were no significant differences in immune cell function between MAPs and N&S. No serious adverse events were reported in MAPs. Erythema was more common after MAP application than N&S but was brief and well tolerated. Lower pain scores were usually reported after MAP application than N&S. Most studies found MAPs easy to use and highly acceptable among healthcare professionals, laypeople and parents. CONCLUSION: MAPs for vaccination were safe and well tolerated and evoked similar or enhanced immunogenicity than N&S, but further research is needed. Vaccine uptake may be increased using MAPs due to less pain, enhanced thermostability, layperson and self-administration. MAPs could benefit at-risk groups and low and middle-income countries.

Association of urinary sex hormones with mood and behavior changes in a community adolescent cohort.

OBJECTIVE: To examine the contribution of variation in sex hormone excretion to mood and behavioral changes in adolescent females and males. DESIGN: Prospective, longitudinal observational cohort study. METHODS: Participants were 342 volunteers aged 10-12 years living in rural Australia. Urinary estradiol and testosterone levels measured by liquid chromatography-mass spectrometry were obtained at three-month intervals for three years. Integrated measures (area-under-curve) of urinary steroid excretion summarised as absolute and variability during each 12-month period of the study. Psychosocial data were gathered annually with the primary outcome of depressive symptomatology. Secondary outcomes were the other subscales of the Youth Self-Report, impulsive-aggression, sleep habits, and self-harm. RESULTS: 277 (158 male) participants contributed data over the full duration of the study and could be included in the analyses. In females, analyses of absolute urine hormone levels found no relationship between estradiol and any outcome, but higher testosterone was significantly associated with depression and poorer sleep. Greater variability of both urine estradiol and testosterone was associated with lower total psychopathology, anxious/depressed and social problems scores. Greater variability in urine estradiol was associated with lower attention problems and impulsive aggression in females. In males, higher testosterone and estradiol levels were associated with rule-breaking, and poorer sleep, and no associations were found for gonadal hormone variability for males. CONCLUSIONS: Longitudinal measurement of both iso-sexual and contra-sexual gonadal hormones contributes to a more nuanced view of the impact of sex steroids on mood and behavior in adolescents. These findings may enlighten the understanding of the impact of sex steroids during normal male and female puberty with implications for hormone replacement therapies as well as management of common mood and behavioral problems.

Childhood and Adolescence Gender Role Nonconformity and Gender and Sexuality Diversity in Young Adulthood.

Importance: Sexuality- and gender-diverse youth experience disproportionate health and social adversity. Accurate early-life indicators are important for development of supportive approaches. Objective: To examine whether commonly used items measuring childhood conformity to gender roles are associated with sexual orientation in young adulthood. Design, Setting, and Participants: This single-center, prospective cohort study (the Raine Study) assessed 2868 children of 2900 women who were recruited during pregnancy from August 1, 1989, to April 30, 1992, with follow-up ongoing. The Achenbach System of Empirically Based Assessment (ASEBA) Child Behavior Checklist, Teacher Report Form, and Youth Self-Report tools were used to survey parents, teachers, and youths to examine gender diversity among the participating youths. Parents were followed up at years 5, 8, 10, 14, and 17, adolescents at years 14, 17, and 27, and teachers at years 10 and 14. Data were analyzed from August 1, 2020, to July 31, 2023. Exposures: Parent and teacher report that a child "behaves like the opposite sex" (gender role behavior), and parent and self-report that a child "wishes to be the opposite sex" (gender role wish), in response to assessment items. Main Outcome Measures: Year 27 self-reported sexual identity, attraction, and behavior. Results: Of the 2868 children in the original birth cohort, 1154 (40.2%) participated in the year 27 follow-up, of whom 608 (52.7%) were recorded female at birth and 546 (47.3%) were recorded male at birth. Of these, 582 who were recorded female at birth continued to identify as female (cisgender) (95.7%), and 515 recorded male at birth continued to identify as male (cisgender) (94.3%); 47 (4.1%) did not complete the questionnaire. Of cisgender participants, 76 of 605 women (12.6%) and 52 of 540 men (9.6%) had a diverse sexual identity, 204 of 605 women (33.8%) and 77 of 540 men (14.3%) were same-gender attracted, and 100 of 605 women (18.6%) and 39 of 540 men (7.2%) had ever engaged in same-gender sexual behavior. Across all follow-ups, after adjusting for gender, nonconforming gender role behavior was consistently associated with diverse sexual identity and behavior (adjusted odds ratio [aOR] for identity, 2.8; 95% CI, 1.9-4.2; behavior aOR, 2.4; 95% CI, 1.6-3.5). Self-reported gender role wish was consistently associated with diverse sexual orientation (identity aOR, 2.3; 95% CI, 1.4-3.8; attraction aOR, 1.7; 95% CI, 1.1-2.5; behavior aOR, 1.9; 95% CI, 1.2-2.9). Conclusions and Relevance: In this cohort study, ASEBA gender role nonconformity was associated with diverse sexual orientation, beginning in early childhood. Findings suggest that the ASEBA measures should not be used to infer sexual orientation or gender diversity in clinical or research settings; asking direct questions may provide more accurate data.

Vaccine microarray patch self-administration: An innovative approach to improve pandemic and routine vaccination rates.

The high-density microprojection array patch (HD-MAP) is a novel vaccine delivery system with potential for self-administered vaccination. HD-MAPs provide an alternative to needle and syringe (N&S) vaccination. Additional advantages could include reduced cold-chain requirements, reduced vaccine dose, reduced vaccine wastage, an alternative for needle phobic patients and elimination of needlestick injuries. The drivers and potential benefits of vaccination by self-administering HD-MAPs are high patient acceptance and preference, higher vaccination rates, speed of roll-out, cost-savings, and reduced sharps and environmental waste. The HD-MAP presents a unique approach in pandemic preparedness and routine vaccination of adults. It could alleviate strain on the healthcare workforce and allows vaccine administration by minimally-trained workers, guardian or subjects themselves. Self-vaccination using HD-MAPs could occur in vaccination hubs with supervision, at home after purchasing at the pharmacy, or direct distribution to in-home settings. As a result, it has the potential to increase vaccine coverage and expand the reach of vaccines, while also reducing labor costs associated with vaccination. Key challenges remain around shifting the paradigm from medical professionals administrating vaccines using N&S to a future of self-administration using HD-MAPs. Greater awareness of HD-MAP technology and improving our understanding of the implementation processes required for adopting this technology, are critical factors underpinning HD-MAP uptake by the public.

Perceived facilitators and barriers to the uptake of the human papillomavirus (HPV) vaccine among adolescents of Arabic-speaking mothers in NSW, Australia: A qualitative study.

Background: Australia has a large immigrant population but there is little data regarding whether human papillomavirus (HPV) vaccination coverage in adolescents varies according to parents' cultural or ethnic background. This work aims to identify facilitators and barriers to HPV vaccination of adolescents as perceived by Arabic-speaking mothers in Western Sydney, South Western Sydney and Wollongong, NSW, Australia. Methods: A purposive sampling approach was applied to recruit mothers of adolescents from Arabic speaking backgrounds who had at least one child eligible for the HPV school-based vaccination program. Face-to-face semi-structured well as online interviews were conducted in Arabic between April 2021 and July 2021. The interviews were audio-recorded, transcribed, and translated into English and examined using thematic analysis. Results: Sixteen mothers of adolescents from Arabic backgrounds described facilitators and barriers to HPV vaccination. A) Facilitators of HPV vaccination included: knowledge of HPV disease, trust in the school vaccination program, opportunistic recommendations from healthcare workers, information from friends. B) Barriers to accessing HPV vaccination included communication gaps: breakdown in school-parent information flow, lack of access to the Arabic language version of the information sheet, mother - GP communication barriers, mother-child communication gap; and health system gaps: missed opportunities for vaccination. C) Mothers' suggestions to improve HPV vaccination acceptance: to involve religious and cultural leadership, encourage engagement with GPs, and provide school-based education for parents and students. Conclusion: Parents could benefit from assistance with HPV vaccination decision making. Interventions via schools, health professionals and religious and cultural organisations could play important roles in HPV vaccination acceptance for Arabic speaking immigrant families and in introducing their adolescent children to this vaccine.

Complex intervention to promote human papillomavirus (HPV) vaccine uptake in school settings: A cluster-randomized trial.

Using a cluster-randomized trial design, we aimed to evaluate a complex intervention to increase uptake of human papillomavirus (HPV) vaccination in schools. The study was undertaken in high schools in Western Australia and South Australia between 2013 and 2015 with adolescents aged 12-13 years. Interventions included education, shared decision-making, and logistical strategies. The main outcome was school vaccine uptake. Secondary outcomes included consent forms returned and mean time to vaccinate 50 students. We hypothesised that a complex intervention would increase 3-dose HPV vaccine uptake. We recruited 40 schools (21 intervention, 19 control) with 6, 967 adolescents. There was no difference between intervention and control (3-dose mean 75.7% and 78.9%, respectively). Following adjustment for baseline covariates, absolute differences in coverage in favour of the intervention group were: dose 1, 0.8% (95% CI, -1.4,3.0); dose 2, 0.2% (95% CI, -2.7, 3.1); dose 3, 0.5% (95% CI, -2.6, 3.7). The percentage of returned consent forms in intervention schools (91.4%) was higher than in control schools (difference: 6%, 95% CI, 1.4, 10.7). There was a shorter mean time to vaccinate 50 students at dose 3. The difference for dose 3 was 110 min (95% CI, 42, 177); for dose 2, 90 min (95% CI, -15, 196); and dose 1, 28 min (95% CI, -71, 127). Logs revealed the inconsistent implementation of logistical strategies. The intervention had no impact on uptake. Inadequate resourcing for logistical strategies and advisory board reluctance toward strategies with potential financial implications impacted the implementation of logistical components.

Exposure to Pornography and Adolescent Sexual Behavior: Systematic Review.

BACKGROUND: Formative experiences in adolescence lay the foundation for healthy and pleasurable romantic and sexual relationships. Exposure to pornography may affect these experiences. OBJECTIVE: We aimed to synthesize evidence published in the past decade on the relationship between exposure to pornography and sexual behavior (earlier age of first sex [<16 years], condomless sex, past-year multiple partners [>1], lifetime multiple partners [>1], group sex, sexual aggression including forced sex, paid sex, teenage pregnancy, and history of sexually transmitted infection) in adolescents aged between 10 and 19 years. METHODS: We identified 19 eligible studies by searching MEDLINE, PsycINFO, Cochrane, CINAHL, Embase, and Web of Science databases from January 2010 to November 2022. RESULTS: Out of 8 studies that assessed earlier age of first sex, 5 studies, including 1 longitudinal study, found a statistically significant association with exposure to pornography. Given that most studies were cross-sectional or had substantial limitations, causal inference could not be made. Also, exposure to pornography was not measured consistently. The evidence was conflicting or insufficient to draw any conclusions regarding other outcomes. CONCLUSIONS: More quantitative research is needed to elucidate the association between pornography exposure and sexual behavior, and sex education should adopt evidence-based approaches to minimize the potential harms from pornography.

The Future Proofing Study: Design, methods and baseline characteristics of a prospective cohort study of the mental health of Australian adolescents.

OBJECTIVES: The Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort. METHODS: The FPS is an Australian school-based prospective cohort study with an embedded cluster-randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self-report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years. RESULTS: The baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05). CONCLUSIONS: This paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence.

Impact of COVID-19 & Response Measures on HIV-HCV Prevention Services and Social Determinants in People Who Inject Drugs in 13 Sites with Recent HIV Outbreaks in Europe, North America and Israel.

HIV/HCV prevention among people who inject drugs (PWID) is of key public health importance. We aimed to assess the impact of COVID-19 and associated response measures on HIV/HCV prevention services and socio-economic status of PWID in high-HIV-risk sites. Sites with recent (2011-2019) HIV outbreaks among PWID in Europe North America and Israel, that had been previously identified, were contacted early May 2020. Out of 17 sites invited to participate, 13 accepted. Semi-structured qualitative site reports were prepared covering data from March to May 2020, analyzed/coded and confirmed with a structured questionnaire, in which all sites explicitly responded to all 103 issues reported in the qualitative reports. Opioid maintenance treatment, needle/syringe programs and antiretroviral treatment /hepatitis C treatment continued, but with important reductions and operational changes. Increases in overdoses, widespread difficulties with food and hygiene needs, disruptions in drug supply, and increased homelessness were reported. Service programs rapidly reformed long established, and politically entrenched, restrictive service delivery policies. Future epidemic control measures should include mitigation of negative side-effects on service provision and socio-economic determinants in PWID.

RESUMEN: La prevención del VIH/VHC entre las personas que se inyectan drogas (PWID) es de vital importancia para la salud pública. Nuestro objetivo fue evaluar el impacto de COVID-19 y las medidas de respuesta asociadas en los servicios de prevención del VIH/VHC y el estado socioeconómico de las PWID en sitios de alto riesgo de VIH. Se contactó con sitios con brotes recientes (2011­2019) de VIH entre PWID en Europa, América del Norte e Israel, que habían sido previamente identificados, a principios de mayo de 2020. De los 17 sitios invitados a participar, 13 aceptaron. Se prepararon informes cualitativos semiestructurados del sitio que cubrían los datos de marzo a mayo de 2020, analizados/codificados y confirmados con un cuestionario estructurado, en el que todos los sitios respondieron explícitamente a los 103 asuntos reportados en los informes cualitativos. El tratamiento de mantenimiento con opiáceos, los programas de agujas/jeringas y el tratamiento antirretroviral/tratamiento de la hepatitis C continuaron, pero con importantes reducciones y cambios operativos. Se reportaron aumentos en las sobredosis, dificultades generalizadas con las necesidades alimentarias y de higiene, interrupciones en el suministro de medicamentos y aumento de personas sin hogar. Los programas de servicios reformaron rápidamente las políticas restrictivas de prestación de servicios, establecidas desde hace mucho tiempo y políticamente arraigadas. Las futuras medidas de control de epidemias deben incluir la mitigación de los efectos secundarios negativos en la prestación de servicios y los determinantes socioeconómicos en las PWID.

Guiding, sustaining and growing the public involvement of young people in an adolescent health research community of practice.

BACKGROUND: Public involvement in health research and its translation is well recognized to improve health interventions. However, this approach is insufficiently practised and evidenced in relation to young people. This paper presents an analysis of the process of co-producing a framework, partnership model and a growing network of young people informing and guiding an adolescent health research community of practice. METHODS: A Living Lab is a participatory research approach that brings together a broad range of stakeholders in iterative cycles of research, design, development, pilot-testing, evaluation and delivery to implement effective responses to complex phenomena. The geographical setting for this study was Sydney, NSW, Australia, and involved both youth and adult stakeholders from this region. The study spanned three phases between July 2018 and January 2021, and data collection included a range of workshops, a roundtable discussion and an online survey. RESULTS: The co-production process resulted in three key outputs: first, an engagement framework to guide youth participation in health research; second, a partnership model to sustain youth and adult stakeholder collaboration; third, the growth of the public involvement of young people with a range of projects and partners. CONCLUSIONS: This study investigated the process of co-producing knowledge with young people in an adolescent health community of practice. A reflexive process supported youth and adult stakeholders to collaboratively investigate, design and pilot-test approaches that embed young people's engagement in adolescent health research. Shared values and iterative methods for co-production can assist in advancing mutual learning, commitment and trust in specific adolescent health research contexts. PUBLIC CONTRIBUTION: Young people guiding and informing an adolescent health research community of practice were involved in this study, and one of the participants is a paper co-author.

Social Media Use and Health and Well-being of Lesbian, Gay, Bisexual, Transgender, and Queer Youth: Systematic Review.

BACKGROUND: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals are at higher risk of poor mental health and well-being. Social media platforms can provide LGBTQ youths with a space that counters heteronormative environments and potentially supports mental health and well-being. Mental health includes an individual's state of psychological and emotional well-being and not merely the absence of mental disorders. OBJECTIVE: We sought to identify how LGBTQ youths and adolescents use social media for connection with other LGBTQ peers and groups, identity development, and social support and how these affect mental health and well-being. METHODS: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) procedures were used to guide this review. Searches were conducted in ACM Digital Library, CINAHL, Ovid Embase, Ovid MEDLINE, and Web of Science in March 2021. This review focused on LGBTQ youths aged 10 to 24 years. Included peer-reviewed studies must comprise social media; explore peer connection, identity development, or social support; and be published from 2012 onward. In total, 2 researchers extracted data and performed quality assessments independently using the Newcastle-Ottawa Scale for quantitative articles and the Critical Appraisal Skills Programme for qualitative articles. Qualitative synthesis was performed on articles that satisfied the eligibility criteria. RESULTS: A total of 26 studies (n=15, 58% qualitative; n=8, 31% quantitative; n=3, 12% mixed methods) met the inclusion criteria. Of the 8 quantitative studies, 6 (75%) were cross-sectional, and 2 (25%) were cohort studies. All studies ranged from moderate to high quality. Social media was a popular tool used by LGBTQ youths to connect with LGBTQ communities. In qualitative data, we found that LGBTQ youths negotiated and explored identity and obtained support from peers on social media. Instagram, Tumblr, and Twitter were commonly used to access LGBTQ content owing to ease of anonymity. Identity management was the most studied social media affordance, important to LGBTQ youths for strategic disclosure. Key strategies for managing identities included being anonymous, censoring locations or content, restricting audiences, and using multiple accounts. Quantitative studies (3/8, 38%) showed that social media was associated with reduced mental health concerns and increased well-being among LGBTQ youths. Mental health concerns arising from social media use were attributed to discrimination, victimization, and policies that did not accommodate changed identities. CONCLUSIONS: We found that social media may support the mental health and well-being of LGBTQ youths through peer connection, identity management, and social support, but findings were limited by weaknesses in the evidence. More robust and longitudinal studies are needed to determine the relationship between social media use and LGBTQ mental health, particularly among adolescents. The findings may inform interventions to promote social media health literacy and the mental health and well-being of this vulnerable group.

Health, social and economic implications of adolescent risk behaviours/states: protocol for Raine Study Gen2 cohort data linkage study.

Background: Risk-taking behaviours are a major contributor to youth morbidity and mortality. Vulnerability to these negative outcomes is constructed from individual behaviour including risk-taking, and from social context, ecological determinants, early life experience, developmental capacity and mental health, contributing to a state of higher risk. However, although risk-taking is part of normal adolescent development, there is no systematic way to distinguish young people with a high probability of serious adverse outcomes, hindering the capacity to screen and intervene. This study aims to explore the association between risk behaviours/states in adolescence and negative health, social and economic outcomes through young adulthood. Methods: The Raine Study is a prospective cohort study which recruited pregnant women in 1989-91, in Perth, Western Australia. The offspring cohort (N = 2,868) was followed up at regular intervals from 1 to 27 years of age. These data will be linked to State government health and welfare administrative data. We will empirically examine relationships across multiple domains of risk (for example, substance use, sexual behaviour, driving) with health and social outcomes (for instance, road-crash injury, educational underachievement). Microsimulation models will measure the impact of risk-taking on educational attainment and labour force outcomes. Discussion: Comprehensive preventive child health programmes and policy prioritise a healthy start to life. This is the first linkage study focusing on adolescence to adopt a multi-domain approach, and to integrate health economic modelling. This approach captures a more complete picture of health and social impacts of risk behaviour/​states in adolescence and young adulthood.

Adolescents' self-efficacy and digital health literacy: a cross-sectional mixed methods study.

BACKGROUND: The internet and social media are increasingly popular sources of health information for adolescents. Using online health information requires digital health literacy, consisting of literacy, analytical skills and personal capabilities such as self-efficacy. Appraising trustworthiness and relevance of online health information requires critical health literacy to discriminate between sources, critically analyse meaning and relevance, and use information for personal health. Adolescents with poor digital health literacy risk using misinformation, with potential negative health outcomes. We aimed to understand adolescents' contemporary digital health literacy and compared self-efficacy with capability. METHODS: Adolescents (12-17 years) completed an eHEALS self-report digital health literacy measure, a practical search task using a think-aloud protocol and an interview to capture perceived and actual digital health literacy. eHEALS scores were generated using descriptive statistics, search tasks were analysed using an observation checklist and interviews were thematically analysed based on Social Cognitive Theory, focussing on self-efficacy. RESULTS: Twenty-one participants generally had high self-efficacy using online health information but perceived their digital health literacy to be higher than demonstrated. They accessed online health information unintentionally on social media and intentionally via search engines. They appraised information medium, source and content using general internet searching heuristics taught at school. Information on social media was considered less trustworthy than websites, but participants used similar appraisal strategies for both; some search/appraisal heuristics were insufficiently nuanced for digital health information, sometimes resulting in misplaced trust or diminished self-efficacy. Participants felt anxious or relieved after finding online health information, depending on content, understanding and satisfaction. They did not act on information without parental and/or health professional advice. They rarely discussed findings with health professionals but would welcome discussions and learning how to find and appraise online health information. CONCLUSIONS: Whilst adolescents possess many important digital health literacy skills and generally feel self-efficacious in using them, their critical health literacy needs improving. Adolescents desire increased digital health literacy so they can confidently appraise health information they find online and on social media. Co-designed educational interventions with adolescents and health providers are required.

Measuring school level attributable risk to support school-based HPV vaccination programs.

BACKGROUND: In Australia in 2017, 89% of 15-year-old females and 86% of 15-year-old males had received at least one dose of the HPV vaccine. However, considerable variation in HPV vaccination initiation (dose one) across schools remains. It is important to understand the school-level characteristics most strongly associated with low initiation and their contribution to the overall between-school variation. METHODS: A population-based ecological analysis was conducted using school-level data for 2016 on all adolescent students eligible for HPV vaccination in three Australian jurisdictions. We conducted logistic regression to determine school-level factors associated with lower HPV vaccination initiation (< 75% dose 1 uptake) and estimated the population attributable risk (PAR) and the proportion of schools with the factor (school-level prevalence). RESULTS: The factors most strongly associated with lower initiation, and their prevalence were; small schools (OR = 9.3, 95%CI = 6.1-14.1; 33% of schools), special education schools (OR = 5.6,95%CI = 3.7-8.5; 8% of schools), higher Indigenous enrolments (OR = 2.7,95% CI:1.9-3.7; 31% of schools), lower attendance rates (OR = 2.6,95%CI = 1.7-3.7; 35% of schools), remote location (OR = 2.6,95%CI = 1.6-4.3; 6% of schools,) and lower socioeconomic area (OR = 1.8,95% CI = 1.3-2.5; 33% of schools). The highest PARs were small schools (PAR = 79%, 95%CI:76-82), higher Indigenous enrolments (PAR = 38%, 95%CI: 31-44) and lower attendance rate (PAR = 37%, 95%CI: 29-46). CONCLUSION: This analysis suggests that initiatives to support schools that are smaller, with a higher proportion of Indigenous adolescents and lower attendance rates may contribute most to reducing the variation of HPV vaccination uptake observed at a school-level in these jurisdictions. Estimating population-level coverage at the school-level is useful to guide policy and prioritise resourcing to support school-based vaccination programs.

Usability, acceptability, and feasibility of a High-Density Microarray Patch (HD-MAP) applicator as a delivery method for vaccination in clinical settings.

BACKGROUND: High-density microarray patch (HD-MAP) vaccines may increase vaccine acceptance and use. We aimed to ascertain whether professional immunizers (PIs) and other healthcare workers (HCWs) in Australia, a High-Income Country (HIC), found the HD-MAP applicator usable and acceptable for vaccine delivery. METHODS: This feasibility study recruited PIs and HCWs to administer/receive simulated HD-MAP administration, including via self-administration. We assessed usability against essential and desirable criteria. Participants completed a survey, rating their agreement to statements about HD-MAP administration. A subset also participated in an interview or focus group. Survey data were analyzed using descriptive statistics, and interviews were transcribed and subject to thematic analysis. RESULTS: We recruited 61 participants: 23 PIs and 38 HCWs. Findings indicated high usability and acceptability of HD-MAP use across both groups by a healthcare professional or trained user and for self-administration with safety measures in place. Most administrations met essential criteria, but PIs, on average, applied the HD-MAP for slightly less time than the required 10-seconds, which the HCWs achieved. PIs perceived safety concerns about home administration but found layperson self-administration acceptable in an emergency, pandemic, and rural or remote settings. CONCLUSIONS: Participants found HD-MAP administration usable and acceptable. Usability and acceptability are likely to be improved through end-user education and training.

Professional immunizers and healthcare workers found high-density microarray patch devices highly usable and acceptable to administer vaccines.HD-MAPs may have advantages over intramuscular injections in clinical settings and in pandemics.Vaccination with HD-MAP may improve acceptance for those with needle-related anxiety.

Mental health and behavioural factors involved in road traffic crashes by young adults: analysis of the Raine Study.

BACKGROUND: Road traffic crashes (RTC) are a leading cause of mortality and morbidity in young people. Severe mental health and behavioural conditions increase the likelihood of RTC, as do a range of driving-risk activities. METHOD: We used data from the Raine Study, a prebirth cohort from Perth, Australia, to assess the relationship between measures of common mental health or behavioural conditions (Child Behavior Checklist Internalising and Externalising scores) at age 17 and subsequent RTC by 27 years, controlling for substance use and driving-risk activities. RESULTS: By 27 years of age, of 937 participants, 386 (41.2%) reported zero crashes and 551 (58.8%) reported ≥1 crashes. In the baseline Poisson model, increased Externalising scores (eg, aggression and delinquency) were associated with increased RTC (incidence rate ratio (IRR)=1.02, 95% CI 1.01 to 1.02): increased Internalising scores (eg, anxiety and depression) were associated with fewer RTC (IRR=0.99, 95% CI 0.98 to 1.00). In the fully adjusted model, the mental health measures were not significant (Externalising IRR=1.01, 95% CI 0.99 to 1.02: Internalising IRR=0.99, 95% CI 0.99 to 1.00). Risky driver activities, such as falling asleep while driving (IRR=1.34), more frequent use of a hands-free telephone (IRR=1.35) and more frequent hostility towards other drivers (IRR=1.30) increased the rate of RTC. CONCLUSION: Measures of mental health scores at age 17 were not predictive of subsequent RTC, after adjusting for measures of driving-risk activities. We need to better understand the determinants of externalising and risky driving behaviours if we are to address the increased risk of RTC.

Emergency Department Initiated Mental Health Interventions for Young People: A Systematic Review.

OBJECTIVE: Young people (10-24 years old) with mental health concerns are increasingly presenting to hospital emergency departments (EDs). The purpose of this review was to identify the core components and outcomes of mental health interventions for young people that are initiated in the ED, such that they are delivered in the ED and/or by ED health workers. METHODS: Six electronic databases were systematically searched. Primary peer-reviewed qualitative or quantitative studies describing an ED-initiated mental health intervention for young people published between 2009 and 2020 were included. RESULTS: Nine studies met the inclusion criteria. The included studies demonstrated that compared with traditional ED care, ED-initiated mental health interventions lead to improved efficiency of care and decreased length of stay, and a core component of this care was its delivery by allied health practitioners with mental health expertise. The studies were limited by focusing on service efficiencies rather than patient outcomes. Further limitations were the exclusion of young people with complex mental health needs and/or comorbidities and not measuring long-term positive mental health outcomes, including representations and whether young people were connected with community health services. CONCLUSIONS: This systematic review demonstrated that ED-initiated mental health interventions result in improved service outcomes, but further innovation and robust evaluation are required. Future research should determine whether these interventions lead to better clinical outcomes for young people and staff to inform the development of best practice recommendations for ED-initiated mental health care for young people presenting to the ED.
