Gender differences in alcohol onset and drinking frequency in adolescents: an application of the theory of planned behavior

The role of psychosocial factors and biological sex on rural Thai adolescents' drinking intention and behaviours: A structural equation model

AIMS

To examine the contributions of psychosocial factors (attitude towards drinking, perceived drinking norms [PDNs], perceived behavioural control [PBC]), and biological sex on drinking intention and behaviours among rural Thai adolescents.

DESIGN

A cross-sectional study design.

METHODS

In 2022, stratified by sex and grade, we randomly selected 474 rural Thai adolescents (Mage  = 14.5 years; SD = 0.92; 50.6% male) from eight public district schools in Chiang Mai Province, Thailand, to complete a self-administered questionnaire. Structural equation modelling with the weighted least square mean and variance adjusted was used for data analysis.

RESULTS

All adolescents' psychosocial factors contributed significantly to the prediction of drinking intention, which subsequently influenced their drinking onset, current drinking and binge drinking pattern in the past 30 days. PDNs emerged as the strongest psychosocial predictor of drinking intention, followed by PBC. Rural adolescents' drinking intention significantly mediated the relationship between all psychosocial factors and drinking behaviours either fully or partially. The path coefficient between drinking attitude and drinking intention was significantly different between males and females.

CONCLUSION

Different from previous studies focus on adolescents' drinking attitude, rural Thai adolescents' PDNs play a significant role on their drinking intention and subsequently their drinking onset and patterns. This nuanced understanding supports a paradigm shift to target adolescents' perceived drinking norms as a means to delay their drinking onset and problematic drinking behaviours.

IMPACT

Higher levels of perceived drinking norms significantly led to the increase in drinking intention among adolescents. Minimizing adolescents' perceptions of favourable drinking norms and promoting their capacity to resist drinking, especially due to peer pressure, are recommended for nursing roles as essential components of health education campaigns and future efforts to prevent underage drinking.

Development of a Web-Based Alcohol Prevention Program Linking School-Child-Family for Intermediate Elementary Students

Family strongly influences student health behavior. However, alcohol-preventive education programs that link parents and school for intermediate-elementary school students remain scarce. Although online educational programs constitute effective interventions to intentionally improve health behaviors, traditional methods are used to implement alcohol- prevention programs for students. In this study, we aimed to (1) develop an online school-child-family alcohol-prevention program based on the theory of planned behavior and (2) examine the preliminary effects of the program on intention to consume alcohol among intermediate-elementary school students. This single-group, pre- and posttest study enrolled 46 Grade 3 students from a public elementary school in a metropolitan South Korea city and ascertained the preliminary effects of a 5-week online alcohol-prevention program by using the alcohol drinking prevention behavior scale. Attitudes, perceived behavioral control, and intention of alcohol-preventive behaviors significantly improved (p < .05) whereas subjective norms did not. The online alcohol-prevention program based on the theory of planned behavior and school-child-family linkage beneficially influenced intention, attitude, and perceived behavioral control for alcohol-prevention behavior, and the effectiveness and convenience of this program underscores its potential application as an educational intervention to improve health behaviors of intermediate-elementary school students.

Focus on Self-Presentation on Social Media across Sociodemographic Variables, Lifestyles, and Personalities: A Cross-Sectional Study

Upward social comparison and aspects of self-presentation on social media such as feedback-seeking and strategic self-presentation may represent risk factors for experiencing negative mental health effects of social media use. The aim of this exploratory study was to assess how adolescents differ in upward social comparison and aspects of self-presentation on social media and whether these differences are linked to sociodemographic variables, lifestyle, or personality. The study was based on cross-sectional data from the "LifeOnSoMe" study performed in Bergen, Norway, including 2023 senior high school pupils (response rate 54%, mean age 17.4, 44% boys). Nine potentially relevant items were assessed using factor analysis, and latent class analysis was used to identify latent classes with distinct patterns of responses across seven retained items. The retained items converged into one factor, called "focus on self-presentation". We identified three groups of adolescents with a low, intermediate, and high focus on self-presentation. Associations between identified latent classes and covariates were assessed using regression analyses. Being a girl, higher extraversion, lower emotional stability, more frequent alcohol consumption, and having tried tobacco were associated with membership in the high-focus group. These results suggest some characteristics that are associated with a higher focus on self-presentation and that could inform targeted interventions.
