The present study demonstrated scale development of the social support (SS), whose measurement should be re-evaluated based on past studies findings. This study aimed for scale development and investigated the dimensionality of items measuring the SS construct. The validation for content and face validity used Modified Delphi Method with seven panelists, however the Exploratory Factor Analysis (EFA) used questionnaires for construct validity and was administered on 100 students in 23 vocational high schools (VHS) as the sampling of this study. A total of 30 initial items were analyzed using Content Validity Index (CVI) that consisted of I-CVI and S-CVI, and was also analyzed with Fleiss Kappa Index (FKI). However, the 25 items were used to collect data in the study, which was then processed using SPSS version 24 on the EFA procedure. The SS-values instrument was found valid. This study's findings could serve as a basis for future research in this area as contribution reliable, and recommended in other relevant studies.
