Objective Improving health literacy at an early age is crucial to personal health and development. Although health literacy in children and adolescents has gained momentum in the past decade, it remains an under-researched area, particularly health literacy measurement. This study aimed to examine the quality of health literacy instruments used in children and adolescents and to identify the best instrument for field use. Design Systematic review. Setting A wide range of settings including schools, clinics and communities. Participants Children and/or adolescents aged 6–24 years. Primary and secondary outcome measures Measurement properties (reliability, validity and responsiveness) and other important characteristics (eg, health topics, components or scoring systems) of health literacy instruments. Results There were 29 health literacy instruments identified from the screening process. When measuring health literacy in children and adolescents, researchers mainly focus on the functional domain (basic skills in reading and writing) and consider participant characteristics of developmental change (of cognitive ability), dependency (on parents) and demographic patterns (eg, racial/ethnic backgrounds), less on differential epidemiology (of health and illness). The methodological quality of included studies as assessed via measurement properties varied from poor to excellent. More than half (62.9%) of measurement properties were unknown, due to either poor methodological quality of included studies or a lack of reporting or assessment. The 8-item Health Literacy Assessment Tool (HLAT-8) showed best evidence on construct validity, and the Health Literacy Measure for Adolescents showed best evidence on reliability. Conclusions More rigorous and high-quality studies are needed to fill the knowledge gap in measurement properties of health literacy instruments. Although it is challenging to draw a robust conclusion about which instrument is the most reliable and the most valid, this review provides important evidence that supports the use of the HLAT-8 to measure childhood and adolescent health literacy in future school-based research.

While adolescent health literacy has gained momentum, it is under-researched from a cross-cultural perspective. This study aims to compare health literacy among two cultural groups of secondary students in Beijing and Melbourne. A cross-sectional study was conducted with 770 students from five secondary schools in Beijing and Melbourne. A self-administered questionnaire was designed to collect information on health literacy (the eight-item health literacy assessment tool (HLAT-8), the Newest Vital Sign (NVS) and the 47-item Health Literacy Survey (HLS-47)), its antecedents and health outcomes. Overall, students’ health literacy in Melbourne (n = 120) was higher than that in Beijing (n = 650): 28.25 ± 6.00 versus 26.37 ± 5.89 (HLAT-8); and 4.13 ± 1.73 versus 3.65 ± 1.64 (NVS). The proportion of students with low health literacy varied by instruments, representing 23.7–32.2% in Melbourne and 29.0%–45.5% in Beijing. In both cultural groups, students’ self-efficacy, social support, and perceptions of school environment were associated with their health literacy, which in turn predicted their health behaviours, patient-provider communication and health status. Given the nature of our study design and small samples, a cautious conclusion would be that adolescent health literacy is sensitive to the broad cultural context and might be an interactive outcome influenced by an individual’s health skills and the social environment. Particularly, creating a supportive school environment is critical to develop adolescent health literacy that would eventually contribute to better health outcomes.

Health literacy is an increasingly important topic in the global context. In mainland China, health literacy measures mainly focus on health knowledge and practices or on the functional domain for adolescents. However, little is known about interactive and critical domains. This study aimed to adopt a skills-based and three-domain (functional, interactive and critical) instrument to measure health literacy in Chinese adolescents and to examine the status and determinants of each domain. Using a systematic review, the eight-item Health Literacy Assessment Tool (HLAT-8) was selected and translated from English to Chinese (c-HLAT-8). Following the translation process, a cross-sectional study was conducted in four secondary schools in Beijing, China. A total of 650 students in Years 7–9 were recruited to complete a self-administered questionnaire that assessed socio-demographics, self-efficacy, social support, school environment, community environment and health literacy. Results showed that the c-HLAT-8 had satisfactory reliability (Cronbach’s α = 0.79; intra-class correlation coefficient = 0.72) and strong validity (translation validity index (TVI) ≥0.95; χ²/ df = 3.388, p < 0.001; comparative fit index = 0.975, Tucker and Lewis’s index of fit = 0.945, normed fit index = 0.965, root mean error of approximation = 0.061; scores on the c-HLAT-8 were moderately correlated with the Health Literacy Study-Taiwan, but weakly with the Newest Vital Sign). Chinese students had an average score of 26.37 (±5.89) for the c-HLAT-8. When the determinants of each domain of health literacy were examined, social support was the strongest predictor of interactive and critical health literacy. On the contrary, self-efficacy and school environment played more dominant roles in predicting functional health literacy. The c-HLAT-8 was demonstrated to be a reliable, valid and feasible instrument for measuring functional, interactive and critical health literacy among Chinese students. The current findings indicate that increasing self-efficacy, social support and creating supportive environments are important for promoting health literacy in secondary school settings in China.

Over the past two decades, health literacy research has gained increasing attention in global health initiatives to reduce health disparities. While it is well-documented that health literacy is associated with health outcomes, most findings are generated from cross-sectional data. Along with the increasing importance of health literacy in policy, there is a lack of specificity and transparency about how to improve health literacy in practice. In this study, we are calling for a shift of current research paradigms from judging health literacy levels towards observing how health literacy skills are developed over the life course and practised in the real world. This includes using a life-course approach, integrating the rationale of precision public health, applying open science practice, and promoting actionable knowledge translation strategies. We show how a greater appreciation for these paradigms promises to advance health literacy research and practice towards an equitable, precise, transparent, and actionable vision.

This study was designed to investigate effects of an integrated intervention on psychosocial competence after abortion in unmarried adolescent pregnancies. Three hundred eighty-five unmarried adolescent pregnancies aged 15 to 24 years (75.1% employed, 24.9% students) were recruited in the study, of which 190 were allocated into the experimental group and the rests as controls. The Rosenberg Self-esteem Scale (SES), the shortened version of Tyler's Behavioral Attributes of Psychosocial Competence Scale-Condensed Form (BAPC-C) and the Nowicki-Stricland Internal-External Locus of Control Scale (NSIE- LOC) were applied to measure self-esteem, coping style, and LOC. Questionnaires were simultaneously administered with abortion service and two-months after intervention. The intervention was organized by an interactive and participatory model designed to increase self-awareness and improve ability of coping under stress with a purpose of reducing occurrence of repeat pregnancy and abortion. Our data showed noticeable changes in coping style and LOC in the experimental group, except for self-esteem ability when comparing with the controls. The psychosocial competence was significantly improved after receiving the intervention. Our study indicates that appropriate psychological intervention for unmarried adolescent pregnancies is necessary to rebuild their normal life after the strike.

Health literacy is a broad and multidimensional construct, making its measurement and conclusions inconsistent. This study aims to compare the patterning of health literacy using different assessment tools and examine their impact on children’s developmental outcomes. A cross-sectional study was conducted with 650 students in Years 7–9 from four secondary schools in Beijing. Health literacy was measured by the eight-item health literacy assessment tool (HLAT, score range 0–37), the six-item Newest Vital Sign (NVS, score range 0–6), and the 16-item Health Literacy Survey (HLS, score range 0–16). Based on Manganello’s health literacy framework, information on upstream factors (e.g., gender, ethnicity, socioeconomic status) and developmental outcomes (e.g., health-promoting behaviours, health service use, global health status) was collected. Overall, the average scores for health literacy were 26.34 ± 5.89, 3.64 ± 1.64, and 13.72 ± 2.94, respectively, for HLAT, NVS, and HLS. The distribution of health literacy varied by socio-demographics and individual characteristics except for gender, no matter which health literacy assessment tool was used. The magnitude of associations between health literacy, its upstream factors and developmental outcomes was greater when using three-domain instruments (HLAT and HLS) than using single-domain instruments (NVS). The approach to health literacy measurement will influence the conclusion. Using multidimensional assessment tools may better capture a child’s health literacy and contribute to the maximum efficiency and effectiveness of school-based health literacy interventions.
