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.

Validation of the Proposed Specifiers for Conduct Disorder (PSCD) Self-Report Version in Iranian School-Attending Adolescents.

The Proposed Specifiers for Conduct Disorder (PSCD) scale was developed to advance the study of child and adolescent psychopathy, especially as it relates to conduct disorder. This study is the first to test the factor structure, measurement invariance, internal consistency, and validity of the Persian PSCD self-report version in a gender-mixed sample of 1,506 school-attending 11 to 18 years old youth (M age = 15.23; SD = 1.83; 49.60% boys). Confirmatory factor analysis supported the proposed four-factor hierarchical structure of the PSCD, though with 19 items loaded on grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder components. This factor structure was also invariant across gender. The PSCD total and four components scores were internally consistent and exhibited the expected relations with proactive aggression, externalizing problems, anxiety and depression, and poor school performance, supporting the PSCD scores' convergent, discriminant, and criteria validity. The findings indicated that with some modifications, the Persian PSCD might hold promise for assessing psychopathy components in Iranian school-attending adolescents and may spark additional research in a variety of settings.

Psychometric properties of the Persian version of the Autism-Spectrum Quotient (AQ-19) with Iranian university students.

Studies suggest that autistic traits are widespread among the general population and, in this regard, the short form of the Autism-Spectrum Quotient (AQ), the AQ-28, was developed to measure autistic traits. The present study examines the factor structure, internal consistency, and convergent validity of the Persian version of the AQ-28 with 691 Iranian university students (Mage = 28.67, SD = 8.57, 57.3% women) who were recruited online and completed the AQ-28 and Symptom Checklist (SCL-25) measures. Confirmatory factor analysis results yielded a four-factor model, which was internally consistent and demonstrated hypothesized correlations with the external correlates of interest (e.g., anxiety, depression, and phobia). Results support the Persian version of the AQ with 19 items (AQ-19) as a measure with sound psychometrics to be used in studies with Iranian university students.

The Explanation of Adolescent Delinquent Behaviors Based on Jessor's Problem Behavior Theory (PBT) in Iran: The Role of Individual Vulnerability, Opportunity Risk Availability, and Perceived Support.

This study tested the generality of Problem Behavior Theory (PBT) in explaining adolescents' problem behavior in Iran. Data were collected from 392 adolescents (Mage = 15.97, SD = 1.12, 55.4% girls) who completed the Adolescent Health and Development Questionnaire (AHDQ) to assess the individual vulnerability, opportunity risk availability, perceived support, and delinquent behaviors. Results indicated that individual vulnerability and opportunity risk availability had a significant relationship with delinquent behaviors and a significant interaction with perceived support in their influence on delinquent behaviors. Further, perceived support was negatively associated with delinquent behaviors. Our results were consistent with PBT's explanatory model for adolescents' problem behavior in Western countries and are informative about problem behavior involvement among Iranian adolescents and the design of interventions.

Comparison of Autistic Traits Between Iranian Students With Different Ethnic Backgrounds: A Cross-Cultural Study.

Autistic traits (ATs) include symptoms associated with autism spectrum conditions (ASCs), which are assumed to be continuously distributed across the general population. Studies have indicated the cultural differences in the expression of ATs. Notwithstanding, our literature review indicated that studies on cross-cultural differences in the expression of ATs included samples from different countries. This is the first study designed to compare the expression of ATs between different ethnicities from the same country. Using the Autism-spectrum Quotient (AQ-28), we examined the possible cultural differences in the expression of autistic traits from four groups of students with different ethnic backgrounds, including Turkish (n = 262), Persian (n = 290), Kurdish (n = 300), and Luri (n = 307) students. Behaviors associated with autistic traits were reported overall higher for males than females. Also, significant cultural differences in autistic traits were found that were different for males and females. Furthermore, while the medical sciences student group scored significantly higher than the humanities group in the Imagination dimension, the humanities group had significantly higher scores in Number/Pattern dimensions than the engineering and medical sciences groups. Altogether, our results provide further support for the idea that the expression of ATs is significantly influenced by culture. A significant limitation of the current study was that groups were not matched with respect to age, percentage of male participants, and fields of studies and that these variables may influence the AQ scores.

The Persian Self-Report Version of the Antisocial Process Screening Device (APSD-P): A Psychometric Evaluation.

The self-report version of the Antisocial Process Screening Device (APSD) is a commonly used tool for assessing psychopathic traits in youth. This is the first study designed to examine the factor structure, internal consistency, and convergent validity of the Persian APSD-SR in a sample of 675 school-attending youth in Iran (46% girls; M age = 16.35). Confirmatory factor analysis supported a modified three-factor model, with items loading on narcissism, callous-unemotional, and impulsivity dimensions, which was invariant across gender. Notwithstanding that the internal consistency of some APSD scores was unsatisfactory, the APSD total and dimension scores showed the expected relations with external correlates (e.g., conduct problems, aggression, and low prosocial behavior), supporting the validity of the interpretation of the APSD scores. The findings showed that the APSD is a useful tool for assessing psychopathic traits in Iranian adolescents and may spark research on adolescent psychopathy in mental health and forensic settings.

Psychometric Properties of the Persian Version of the Teasing Questionnaire 23.

The current study was a cross-sectional research and aimed to investigate the factor structure, internal consistency, and validities of the Persian version of the Teasing Questionnaire-Revised (TQ-R). Forward and backward translations of the TQ-R were performed; face and content validities were determined based on comments by a sample of psychology students and specialists. Using the cluster sampling method, 290 participants were recruited, and 201 valid data (M age = 23.53, SD = 3.53, 64.2% men) were analyzed. The factor structure was assessed by confirmatory and exploratory factor analysis (EFA). The result of the confirmatory factor analysis(es) did not confirm the proposed three, four, and five-factor models. EFA revealed four factors with 23 items, explaining 52.03% of the total variance. The internal consistency of the Persian version of Teasing Questionnaire 23 was in the excellent range (α = 0.92), and its expected associations with external correlates (e.g., depression and anxiety) supported the measure's convergent validity. The findings indicated that the Persian version of the TQ-R has sound psychometric properties and can be used as a valid and reliable tool in research and clinical outcomes.

Predicting Academic Alienation From Emotion Dysregulation, Social Competence, and Peer Relationships in School-Attending Girls: A Multiple-Regression Approach.

School alienation (SA) refers to a collection of negative attitudes toward the social and academic realms of schooling consisting of cognitive and affective components. The current study was designed to examine whether emotion dysregulation, social competence, and peer problems predict school alienation. In this vein, 300 school-attending adolescents in Sarab were recruited and completed difficulties in emotion regulation scale (DERS), academic alienation questionnaire (AAQ), social competence test (SCT), and index of peer relations (IPR) measures, but 280 (M age = 16.35; SD = 0.82; 46% girls) completed data were gathered. The results of hierarchical multiple regression indicated that school alienation was significantly predicted by emotion dysregulation, social competency, and peer problems. In conclusion, our findings suggest that school psychologists and other clinicians design interventions to improve the students' shortcomings in emotion regulations, social competency, and peer relationships domains.

The Influence of Shift Work on the Quality of Sleep and Executive Functions.

Shift work is an inconsistent and atypical work schedule. This study aimed to investigate the influence of shift work on the Quality of Sleep (QOS) and Executive Functions (EF). Thirty shift workers and thirty day workers first completed a demographic questionnaire. They then were tested using the Pittsburgh Sleep Quality Index (PSQI) and EF tests, including the Corsi Block-Tapping Task (CBTT), Berg's Card Sorting Task (BCST), and the Continuous Performance Task (CPT). Results were subjected to non-parametric Chi-Square Tests, the Mann-Whitney U Test, and Independent T-Tests. Shift workers had significantly poorer sleep quality than day workers, which was shown in PSQI global scale (p = 0.001), sleep duration (p = 0.042), habitual sleep efficiency (p = 0.021), and sleep disturbance (p = 0.021). Concerning EF tests, shift workers performed significantly poorer on CBTT (p = 0.019) and BCST (p = 0.015, 0.047) compared with day workers. Significant differences were also observed between shift workers and day workers in terms of variables of omission errors (p = 0.037) and commission errors (p = 0.041) on CPT, but no significant difference was found between shift workers and day workers in reaction time (p = 0.561). Shift work impaired EF. These findings are related to shift workers' poorer sleep and its detrimental effects on areas of the brain, which are critical for EF, such as the prefrontal area. Our results suggest the evaluation and implication of practices and policies to assuage the consequences of working in shifts.
