This study aimed to evaluate the psychometric properties of the Brief Interpersonal Competence Questionnaire (ICQ-15) administered to Chinese adolescents. A sample of 1705 adolescents (Mean age = 14.08, SD = 3.22, 46.5% male) completed a questionnaire including the Chinese version of the ICQ-15, as well as measurements of well-being, psychological resilience, and depression. To examine the psychometric properties of the ICQ-15, item analyses (item-total correlation and normality test), confirmatory factor analysis, concurrent validity analyses, multi-group analyses, and internal consistency analyses were performed. The results of the item analyses suggested a good item-total correlation, and the item scores were distributed approximately normally. The confirmatory factor analysis showed that the five-factor model had acceptable fit indices. The concurrent validity analyses indicated that the Chinese version of the ICQ-15 had a satisfactory concurrent validity. The multi-group analyses proved the measurement invariance across females and males, as well as participants in early, middle, and late adolescence. The ICQ-15 demonstrated satisfactory internal consistency reliability among Chinese adolescents. The ICQ-15 presents good psychometric properties and can be used to assess interpersonal competence in Chinese adolescents.
