“…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;.…”

“…The results are consistent with other studies, for example, Yamauchi et al (2007) indicated that the Japanese-version Paranoia Checklist (JPC) scores positively correlated with the Paranoia Scale and the Peters et al Delusions Inventory (PDI). In two studies, Yamauchi et al (2009a) found that the Paranoia Checklist correlated with the Spielberger Trait Anger Expression Inventory in undergraduate students, and Yamauchi et al (2009c) showed that the JPC positively correlated with trait anxiety, social anxiety, and anger, and negatively correlated with social support. reported that the Paranoia Checklist correlated .52 with the Positive and Negative Syndrome Scale (PNSS).…”

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.

Background: Flow experience is thought to enhance health-related quality of life by mitigating stress and providing a sense of achievement. The associations between flow experience and subclinical psychiatric anomalies, such as schizotypal personality traits and paranoid ideation, have not been examined. Objectives: This study aimed to evaluate the associations between flow experience and subclinical psychiatric anomalies in a healthy population. Materials and Methods: This cross-sectional study included 64 undergraduates from Kibi international university, Japan (42 males, 22 females; mean age 20.1 ± 1.13 years). Schizotypal personality was measured using the Japanese version of the Oxford Schizotypal Personality Scale (STA). Paranoia was measured using the Japanese-version Paranoia Checklist (JPC). Flow experience was measured using the Flow Experience Checklist (FEC). Results: Both the STA score and the JPC distress subscore were positively correlated with the FEC score. However, no correlation was observed between either the JPC conviction or the frequency subscore and the FEC score. Stepwise multiple regression analysis revealed that the FEC score was influenced only by the STA score. Conclusions: Schizotypal personality traits appear to enhance the quality of flow experiences, but not their frequency or duration. We suggest that these intense flow experiences serve as a distraction from psychological abnormalities, such as paranoid ideation.

“…To assess paranoid thought, the Japanese version of the PCL 21 was used. 22 The checklist consists of 18 self-report items, each rated on a five-point scale (ranging from 1= “not at all applicable” to 5= “extremely applicable”, with a possible score ranging from 18 to 90), that evaluate the frequency, degree of conviction, and level of distress experienced. The checklist has good internal reliability and is considered appropriate to measure subclinical persecutory ideation.…”

BackgroundIf delusions serve as a defense mechanism in schizophrenia patients with paranoia, then they should show normal or high explicit self-esteem and low implicit self-esteem. However, the results of previous studies are inconsistent. One possible explanation for this inconsistency is that there are two types of paranoia, “bad me” (self-blaming) paranoia and “poor me” (non-self-blaming) paranoia. We thus examined implicit and explicit self-esteem and self-blaming tendency in patients with schizophrenia and schizoaffective disorder. We hypothesized that patients with paranoia would show lower implicit self-esteem and only those with non-self-blaming paranoia would experience a discrepancy between explicit and implicit self-esteem.MethodsParticipants consisted of patients with schizophrenia and schizoaffective disorder recruited from a day hospital (N=71). Participants were assessed for psychotic symptoms, using the Brief Psychiatric Rating Scale (BPRS), and self-blaming tendency, using the brief COPE. We also assessed explicit self-esteem, using the Rosenberg Self-Esteem Scale (RSES), implicit self-esteem, using Brief Implicit Association Test (BIAT), and discrepancy between explicit and implicit self-esteem.ResultsContrary to our hypothesis, implicit self-esteem in paranoia and nonparanoia showed no statistical difference. As expected, only patients with non-self-blaming paranoia experienced a discrepancy between explicit and implicit self-esteem; other groups showed no such discrepancy.ConclusionThese results suggest that persecutory delusion plays a defensive role in non-self-blaming paranoia.
