The Proposed Specifiers for Conduct Disorder (PSCD) in Iranian School-Attending Adolescents: A Multi-Informant Validation Study of the PSCD Parent- and Youth Self-Report Versions.

The Proposed Specifier for Conduct Disorder (PSCD) was developed to measure the broad psychopathy construct with grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder subscales. This study tested the psychometric properties of Persian parent-and-child self-report PSCD versions with 974 parents (86% mothers) and children/adolescents (46.5% boys) dyads. Results showed that with some modifications the proposed hierarchical four-factor structure for both PSCDs was confirmed and was found to be invariant across gender. Across versions, all PSCD scores were internally consistent and demonstrated expected correlations with parent-reported externalizing problems, anxiety/depression, and poor school performance, supporting the PSCDs scores' validity. This study also is the first to examine and establish acceptable to excellent parent-child agreement of PSCD scores. Finally, all PSCD child-report scores offered small though significant incremental validity over their corresponding PSCD parent-version scores in predicting parent-reported conduct problems and proactive aggression. Findings indicated that both Persian PSCDs may hold promise for assessing psychopathy components in Iranian school-attending adolescents and generating additional research on this topic.
