However, there are no concise measurements to evaluate MI. The initial Mood Instability Questionnaire-Trait (MIQ-T) was developed to fill this gap. The current study aimed to create a short form of MIQ-T (MIQ-T-SF) that measures MI with high validity and reliability in the Korean general population.Methods Of the 59 items in the MIQ-T, 17 items were chosen for the MIQ-T-SF following the factor analysis process. In total, 540 participants completed the MIQ-T-SF. Cronbach\u2019s alpha and McDonald\u2019s omega were used to evaluate reliability. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to determine construct validity. Concurrent validity was confirmed via comparisons with Personality Assessment Inventory-Borderline Features Scale. Measurement invariance across gender and age groups was confirmed before analyzing differences in scores using Kruskal-Wallis test.Results The MIQ-T-SF displayed expected correlations and high internal consistency (\u03b1=0.71\u20130.90, \u2126t=0.72\u20130.92). Using EFA and CFA, a five-factor structure was confirmed. Measurement invariance was supported, and gender differences were observed.Conclusion The MIQ-T-SF is an accurate and reliable method to detect MI in the Korean general population. The study\u2019s results offer new perspectives for future studies on MI.<\/jats:p>","DOI":"10.30773\/pi.2022.0275","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T06:33:38Z","timestamp":1684996418000},"page":"408-417","update-policy":"https:\/\/doi.org\/10.30773\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Validation
