This study examined the influence of consumers’ knowledge on their perceptions and purchase intentions toward genetically modified foods, and the implications of these consumer responses for sustainable development in the food industry. This study distinguished between objective and subjective knowledge and identified how an imbalance between the two knowledge types influenced consumers’ attitudes and purchase intentions toward genetically modified foods. Results of a multinomial regression analysis showed that consumers with higher levels of education, income, and food involvement and more exposure to negative information about genetically modified foods tended to overestimate their actual knowledge level. The overestimation group showed a higher risk perception, lower benefit perception, and lower intention to purchase genetically modified foods than other participants. Consumers with less education and higher income were more likely to underestimate their knowledge.

Purpose: The presence of an individual with disability in a family affects the whole family. Families of individuals with cerebral palsy (CP) experience increased psychological anxiety and financial problems; specifically, parents tend to feel time pressure and struggle to maintain their social and cultural activities. Methods: t-Tests and ANOVA with post hoc Tukey tests were used to compare caregiving time, time pressure, and depression between parents. Multivariate logistic regression analysis was used to examine the effect of caregiving time and time pressure on depression in parents. Results: Regarding depression, 58 (38.2%) respondents scored ≥16 on the Center for Epidemiological Studies – Depression scale. Respondents supporting a preschool child spent more time than those supporting adults did; those supporting adults reported less time pressure than those supporting individuals of other ages. Caregiving time’s effect on depression was not supported, whereas increased time pressure raised the risk of depression. Conclusions: The frequency of depression among parents supporting individuals with CP exceeded preceding findings. Time pressure due to support appears to directly predict depression. Total time spent caring appears unrelated to depression.
