Purpose This study aimed to identify distinct subjective viewpoints regarding the perceived effects of energy drink consumption among South Korean male high school students.
Methods Using Q methodology, a concourse of statements was developed through interviews and literature reviews, and refined into 35 Q samples. Forty male high school students were recruited via snowball sampling to reflect diverse consumption patterns and attitudes. Participants sorted the Q samples using a forced distribution procedure. Data were analyzed using the PC-QUANL program.
Results Four distinct groups of male adolescents were identified based on their perceived effects of energy drink consumption: (1) effect-oriented experience sharers, (2) ambivalent recognizers of experience, (3) alternative-seeking evaluators, and (4) emotionally reactive responders. These groups’ perceptions were shaped by peer influence, personal consumption experiences, and levels of self-regulation.
Conclusion By typifying the subjective perceptions of Korean male high school students regarding energy drink consumption, this study provides a foundational understanding of how adolescents interpret and respond to such health behaviors. These insights can guide the development of tailored health education programs that address the unique needs and attitudes of each group.
Purpose The purpose of this study was to test a model for intention to discontinuation drinking high caffeinated beverages among undergraduate students. This model was based on the Ajzen’s theory of planned behavior and Becker’s health belief model.
Methods Participants consisted of 201 undergraduate students. Data were collected by questionnaires from March 11 to May 24, 2019. Collected data were analyzed using SPSS/WIN 22.0, AMOS 22.0 program.
Results The assessment of the model indicated an acceptable fit (normed x2=1.65, goodness-of-fit index [GFI]=.83, adjusted GFI=.79, comparative fit index [CFI]=.92, standardized root mean square residual [SRMR]=.05, Tucker-Lewis index [TLI]=.91, normed fit index [NFI]=.87, root mean square error of approximation [RMSEA]=.07). Perceived behavior control, subjective norm, the subjective attitude was found to have a significant direct effect on the intention to discontinuation of drinking a high caffeinated beverage. The variances of this model explained 45.3% of the variance in intention to discontinuation of drinking a high caffeinated beverage.
Conclusion These results suggest that a need to increase awareness of adverse effects and potential risks of high caffeinated beverage consumption in undergraduate students. Besides, the university and government should provide education and campaigns to prevent excessive high-caffeinated beverage consumption.

Purpose This study aimed to investigate the status of caffeine-containing energy drink consumption among Korean nursing students and to identify associated psychological factors.
Methods In total, 187 Korean nursing students participated in this cross-sectional study. A self-administered questionnaire was used to identify participants' general characteristics and psychosocial factors (self-esteem, academic stress, depression, and college adjustment) associated with energy drink consumption. Data were analyzed with SPSS using descriptive statistics, the x2 test, the t-test, and logistic regression.
Results More than two-thirds (73.3%) of the participants had consumed energy drinks. Among the investigated psychological factors, depression appeared to most strongly influence energy drink consumption behaviors in this population.
Conclusion The consumption of caffeine-containing energy drinks was found to be common among nursing students preparing to become health care professionals; depressed nursing students were more likely to have consumed energy drinks than non-depressed students. Nursing educators should emphasize the early detection of unhealthy beverage consumption habits and provide appropriate education to enhance healthy behaviors in future health care professionals.
