The Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR) is the most recent operationalization of the CAPP model which uses 33 symptoms to conceptualize psychopathic personality disorder. In the current study, we sought to examine the cross-cultural utility of the CAPP-SR in an Iranian sample. In Study 1, we translated the CAPP-SR into Persian and assessed the linguistic convergence between the Persian and original English versions using a sample of Persian–English bilingual university students in New Zealand. In Study 2, we examined the reliability and validity of the Persian CAPP-SR using a sample of university students in Iran. Our results showed that the Persian CAPP-SR has a promising pattern of convergent and incremental validity in terms of their associations with conceptually-relevant criterion measures, including those designed for the Iranian cultural context. Overall, the findings from the current study support the use of the Persian CAPP-SR as well as having implications for the cross-cultural utility of the CAPP model.

Objectives:To compare the effect of exercise and morphine on abstinence syndrome and hippocampal gene expression in rat model.Methods:Thirty adult male rats were exposed to voluntary wheel exercise (low, medium, high) for 28 days. The subjects entered Conditioned Place Preference (CPP) apparatus and experienced morphine (low, medium, high) CPP and followed by naloxone test. Correlation between exercise level, morphine injection, concurrent morphine administration and exercise with morphine CPP, BDNF and TrkB genes was determined. Rats were euthanized, decapitated and the hippocampus was removed. The expression of BDNF and TrkB genes were evaluated by real time PCR.Results:Active rats ran an average of 839.18 m/d. A significant (P<0.001) correlation between exercise level, morphine injection, concurrent morphine administration and exercise with morphine CPP and BDNFand TrKB gene expressions was found.Conclusion:Voluntary exercise in different levels potentiates the brain rewarding system, CPP scale, and hippocampal BDNF and TrKB expressions. High range of voluntary exercise demonstrated an increase in the likelihood of developing addictive and drug-seeking behavior.

Borderline personality disorder (BPD) is a severe psychiatric condition that is associated with functional impairment and pathological traits. It has been argued that identity impairment is one of the core features of BPD, which can be manifested in different ways, including fragmented autobiographical narratives. Here, we considered both the traditional and modern conceptualizations of BPD to examine the relation between identity impairment, as operationalized through autobiographical memory, and features of BPD. We hypothesized that BPD features would be associated with higher levels of fragmentation in narrative identity, narrative intimacy, and narrative coherence in participants' autobiographical memory. To test this hypothesis, we recruited 298 university students who were administered a series of self-report measures of BPD and were asked to describe an autobiographical memory about a turning point in their lives. Narrative identity, but not narrative intimacy nor coherence, was the dominant predictor of BPD features. We discuss our findings in terms of how individuals with features of BPD struggle with many aspects of a distorted sense of self.
