Introduction: The USM Pre-clinical medical students’ guidance and counselling needs questionnaire (USM-MS- GCN-Q) is an English-language guidance and counselling needs questionnaire which was developed specifically for pre-clinical medical students. The aim of this study is to highlight the construct validity of USM-MSGCN-Q among pre-clinical medical students. Methods: In June 2017, a cross-sectional study on 208 pre-clinical medical students was conducted in Universiti Sains Malaysia (USM). This self-administered USM-MSGNC-Q consisted of four constructs and 20 items with a 5-point Likert scale within each item. A confirmatory factor analysis was em- ployed to test the hypothesized measurement model. Results: The final measurement model fitted the data well. The four-factor model initially consisted of 20 items however, it was reduced to 18 items with the goodness of fit indices suggesting good model fit (RMSEA 0.89, GFI .915 and ChiSq/df 2.642). Internal consistency reliability (Cronbach’s alpha) was 0.879 for self-leadership skills, 0.929 for communication skills, 0.871 for learning skills, and 0.870 for psychological coping skills. The overall Cronbach’s value was 0.922. Respective composite reliability values were 0.879,0.952,0.879 and 0.835 while the Average Variance Extracted values were 0.729, 0.911, 0.595 and 0.630. Conclusion: This study has confirmed that self-leadership, communication, learning and psychological coping skills were the components of guidance and counselling needs which influences the effectiveness of guidance and coun- selling sessions with pre-clinical medical students.
