The purpose of this study is determination of factor structure and psychometric features "negative self-picture scale" (NSPS). So, after preparation of mentioned scale and implementation of basic steps as well as omission of possible problems, NSPS was done on 574 Shahed University bachelor students, selected by cluster sampling and factor structure of this tool was surveyed by heuristic confirmatory factor analysis. Results of these analyses represents NSPS 4-factor structure which respectively include: "concerns on appearance of physical defects", " concerns on of social competency defects(1)", " concerns on of social competency defects(2)" concerns on defects and disabilities related to anxiety symptoms control". In order to study NSPS validity and its factors, internal consistency coefficients and retesting coefficients were calculated. Results represent NSPS acceptable validity and its factors. Validity study of NSPS structure and its factors with 6 scales ( SIAS SPS, LSAS-SR,SPIN ,DASS-21, BDI-II) shows that Pearson correlation coefficients between NSPS and other scales is meaningful and only its correlations with LSAS-SR is at least and non-meaningful which will be explained. Generally, this study provides evidences for accuracy of factor structure NSPS acceptable validity.
