“…On the Paranoia Checklist, 37% of the sample showed frequency, degree of conviction, and distress paranoid thoughts (M = 35.50, SD = 7.21). The Cronbach's α for the Paranoia Checklist was .87, indicating good reliability, consistent with research in other countries (e.g., Brown, 2010;Barreto Carvalho et al, 2018;Freeman, Garety, Bebbington, Smith, et al, 2005;Hirao, 2016;Yamauchi et al, 2007Yamauchi et al, , 2009aYamauchi, Sudo, & Tanno, 2009c;.…”

“…It has shown a low positive correlation with a total score for frequency, conviction, and distress The General Paranoia Scale correlated .71 with the Paranoia Checklist frequency, .62 with the conviction, and .58 with the distress scores (Freeman, Garety, Bebbington, Smith, et al, 2005). The Cronbach's α for the German Paranoia Checklist version was .90 or above for some items and .96 for three-dimension Portuguese Paranoia Checklist version (Barreto Carvalho et al, 2018). A typical item is "I need to be on my guard against others."…”

“…There are paranoia thoughts in the normal population (Barreto Carvalho et al, 2018;Barreto Carvalho et al, 2017;Yamauchi, Sudo, & Tanno, 2009b). Subclinical paranoia is estimated to occur in around 10% of the general population (Brown, 2010).…”

Paranoid thought is one of the most common symptoms in psychiatric disorders. The Paranoia Checklist is a brief screening and diagnostic tool for clinical and subclinical paranoia. It has been used in research, clinical, and non-clinical settings. The Paranoia Checklist has not had its validity examined in university settings in Iran. A cross-sectional study was conducted to investigate the validation of the Farsi version of Paranoia Checklist in a randomized cluster sample of 365 Iranian volunteer college students selected from the Payame Noor University of Mashhad in Iran. They completed the Paranoia Checklist, the General Paranoia Scale, and the Symptom Checklist 90 Revised (SCL-90-R). The mean score of the Paranoia Checklist was 35.50 (SD = 7.21). The Cronbach's α for the Paranoia Checklist was .87, indicating high internal consistency. The Paranoia Checklist correlated .42 with the General Paranoia Scale, .38 with the SCL-90-R subscales of Anxiety (ANX), Hostility (HOS), and Paranoia Ideation (PAR), and .37 with the Interpersonal Sensitivity (INTS), denoting moderate construct and criterion-related validity. The results of the factor analysis of the Paranoia Checklist identified three factors associated with the paranoid thoughts. The Paranoia Checklist has a multidimensional structure, and adequate validity and reliability. It can be used in the non-clinical, clinical, and research settings to measure paranoia in Iran.
