The purpose of this study was to evaluate the reliability and validity of a Korean version of the 20-item COVID-19 phobia tool, which was developed through a translation-reverse translation process. These data were collected from 226 persons using a self-reported questionnaire. Exploratory and confirmatory factor analyses were used to test construct validity. Finally, for 19 out of 20 items, the item-level convergence and differential validity were confirmed. In addition, the reliability and validity of the tool as a whole has been verified. For the subscales, Cronbach’s α was 0.90 for psychological, 0.87 for psychosomatic, 0.86 for economic, and 0.87 for social. Appropriate reliability was confirmed. Correlations between the COVID-19 phobia tool and fear of COVID-19 confirmed validity. The Korean version of the COVID-19 phobia tool is an appropriate scale for measuring the fear of COVID-19 and relevant psychological characteristics. Therefore, future studies in areas such as health and nursing could use this tool as required.

The coronavirus (COVID-19) pandemic has emphasized a need to assess the cause of vaccine hesitancy. This study verified the reliability and validity of the Korean versions of the COVID-19 vaccine hesitancy scale and vaccine conspiracy belief scale and the correlation between them. The COVID-19 vaccine hesitancy scale, Korean COVID-19 vaccine hesitancy scale, vaccine conspiracy beliefs scale, and self-efficacy scale were the study tools. Following translation into Korean, back translation into English, content validity verification, and preliminary survey, valid samples were obtained from 400 adults aged >20 years. Exploratory factor analysis revealed that “belief” and “lack of trust” accounted for 62.4% of the total variance. The model fit index of the vaccine conspiracy beliefs scale revealed that all values were in a good range. The Korean version of the COVID-19 vaccine hesitancy scale showed a positive correlation with vaccine conspiracy beliefs (r = 0.74, p < 0.001) and a significant negative correlation with self-efficacy (r = −0.17, p < 0.001). The validity and reliability of the COVID-19 vaccine hesitancy scale and vaccine conspiracy beliefs scale were verified. The Korean versions of the two scales can contribute to programs that measure and mediate various factors influencing vaccination during the COVID-19 pandemic.

Purpose: The aims of this study were to develop a self-determination theory (SDT)-based self-determination improvement program for adolescents with a history of non-suicidal self-injury and to examine the effects of the program on basic psychological needs (i.e. autonomy, competence, and relationship), self-esteem, and non-suicidal self-injury.Methods: This study consisted of a one-group pretest-posttest design. The participants were 33 students in the first and second years of middle school, who were recruited from five middle schools located in a specific area. The participants had a history of non-suicidal self-injury. The experimental group received the SDT-based self-determination improvement program twice a week for 4 weeks. The study was carried out from October 4 to November 26, 2021, and data were analyzed using SPSS for Windows version 25.0 with the paired t-test.Results: The SDT-based self-determination improvement program was effective for basic psychological needs, self-esteem, and non-suicidal self-injury prevention in adolescents with a history of non-suicidal self-injury.Conclusion: The results of this study suggest that the SDT-based self-determination improvement program can be used as an effective mental health nursing intervention to improve basic psychological needs and self-esteem and to prevent non-suicidal self-injury in adolescents with a history of non-suicidal self-injury.
