    (2016) Karim Abdolmohammadi; Ali Mohammadzadeh; Ezatallah Ahmadi; Farhad Ghadiri Sourman
    Abstract Background and Objectives: Considering that paranoid thought has one-dimensional approach, use of long questionnaires has no clinical and research application, therefore use of short questionnaires seems necessary. The Green et al. paranoid thought scale is a short self-assessment tool for assessing paranoid thought in non-clinical and clinical group. This research was conducted to validate this questionnaire in Iranian population. Methods: In this cross-sectional survey, 356 students were selected using stratified sampling method and assessed by GPTS and Minnesota multiphasic paranoid inventory (MMPI) in 2015. Validity was assessed simultaneously with MMPI testing. Results: The correlation coefficient of GPTS and MMPI scores was &alpha;=0.71 and significant (p<0.001). Internal consistency value was estimated to be 0.81 according to Cronbach's alpha coefficient. Conclusion: GPTS is an appropriate and short tool for screening in paranoid thought-related researches.
