Latent Class-Specific Psychosocial and Behavioral Determinants of Preventive Behavioral Intentions for Emerging Infectious Diseases Among Korean Adults: A Mixture Regression Model Approach.
Yong-Hyun Moon, Jihea Choi
PMID 41738476WHAT IT FOUND
Korean adults separated into subgroups with different factors linked to intention to prevent emerging infectious diseases.
The larger subgroup linked to awareness, responsibility, mask habits and prior infection; the smaller subgroup to responsibility, confidence and vaccination, with prior infection linked to lower intention.
Key findings
01The predictors of preventive intentions were not the same in two latent classes; awareness, mask-wearing and prior COVID history differed significantly between classes.
02In latent class 1 (n = 92), awareness, responsibility, vaccination, mask-wearing, age and prior COVID history were significant positive predictors.
03In latent class 2 (n = 57), responsibility, self-efficacy and vaccination were significant positive predictors, while prior COVID history was a significant negative predictor and mask-wearing was not significant.

What it does not show
The cross-sectional design cannot show that these factors caused stronger intentions. All study variables were self-reported, including vaccination and mask-wearing, so recall bias and social desirability bias are possible. Participants were a convenience sample of 149 adults from two Korean cities, so the subgroup patterns may not apply to other populations. The awareness scale was not very consistent (KR-20 = 0.62), so scores on it may be imprecise. The latent classes were unequal in size (92 and 57), and the study notes reduced power for smaller subgroup effects.
The easy way to misread this
Do not read the latent classes as fixed patient types or as proof that tailored nursing messages will improve infection-prevention behavior. The study measured self-reported intentions in a small convenience sample and did not test an intervention.
