Accessible summary The Attitudes Toward Acute Mental Health scale (ATAMHS) was translated into Korean with attention to linguistic and content equivalence. Nine items were eliminated from the Korean version because of low correlations with the overall scale due to differences in clinical nursing environments and culture between South Korea and English‐speaking countries. The results of this study showed that the Korean version of the ATAMHS (ATAMHS‐K) is a reliable and valid scale for measuring attitudes toward mental illness in nurses and nursing students in an acute mental care setting. Factor analysis of the 24‐item ATAMHS‐K revealed three factors: (1) professional perspective; (2) semantic differentials; and (3) positive attitudes. The final analysis revealed that the three factors accounted for 39.5% of the variance. In addition, the ATAMHS‐K was shown to have strong concurrent validity due to its strong positive correlations with the Community Attitudes Toward the Mentally Ill – Korean version (CAMI‐K) scale. This study was the first attempt to adapt the ATAMHS for use in South Korea and to validate it with Korean nurses and nursing students.Abstract The purpose of this study was to adapt the A ttitudes T oward A cute M ental H ealth S cale ( ATAMHS ) into the K orean language and culture and then to determine the reliability and validity of it by administering it to a sample of K orean nursing students and nurses. We conducted a psychometric evaluation that included a two‐step item analysis (analysis and reanalysis), exploratory factor analysis and concurrent validity. The ATAMHS was translated into K orean by bilingual nurses. Then, 429 participants (224 undergraduate nursing students and 205 nurses, all with psychiatric experience) completed the translated version of the ATAMHS . The item analysis revealed that nine items correlated poorly with the rest; thus, they were deleted from the scale. The final K orean version of the scale, which we refer to as the Korean version of the ATAMHS ( ATAMHS ‐ K ), contains 24 items. The ATAMHS ‐ K showed good internal consistency. Exploratory factor analysis revealed three factors (professional perspective, semantic differentials and positive attitudes) that explained 39.5% of the variance. The ATAMHS ‐ K had strong correlations with the K orean version of the C ommunity A ttitudes towards the M entally I ll S cale, thus confirming the concurrent validity. Therefore, the ATAMHS ‐ K demonstrated acceptable psychometric properties as a measure of attitudes toward acute mental health in K orean nursing students and nurses.
