Introduction. Analysis of the relationship between test scores and other variables provides an important source of evidence for validity. As a new instrument, evidence of validity of Pictorial Vocational Interest Inventory (PVII) is needed to support its psychometric properties. The purpose of this study is to obtain evidence of the validity of Pictorial Vocational Interest Inventory (PVII) based on relationships with other instrument which is Vocational Interest Scale (VIS). Method. 570 high school students were asked to complete Pictorial Vocational Interest Inventory (PVII) and Vocational Interest Scale (VIS). The multitrait-multimethod was conducted by correlating the score of the Pictorial Vocational Interest Inventory (PVII) with the score of Vocational Interest Scale (VIS). Results. Evidence of convergent validity was found in the Realistic, Artistic, and Investigative interest types. However, the results of the study did not show evidence of convergent validity for Social, Enterprising, and Conventional interest types. The negative correlation found in the Realistic-Social, Investigative-Enterprising, and Artistic-Conventional interest type relationships indicates the evidence of discriminant validity. Discussion and Conclusion. The evidence of validity obtained in this study supports the evidence of validity that has been obtained previously which are evidence of content validity and evidence of internal structure validity of the Pictorial Vocational Interest Inventory (PVII). The items of Pictorial Vocational Interest Inventory (PVII) need to be developed further to strengthen the representation of each type of interest.
