Background: The Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) are two widely used instruments to screen patients for depression and anxiety. Comparable psychometric properties across different demographic and linguistic groups are necessary for multiple group comparison and international research on depression and anxiety.Objectives and Method: We examine measurement invariance for the PHQ-9 and GAD-7 by: (a) the sex of the participants, (b) recruitment stratum, and (c) linguistic background. This study is based on non-randomized observational data six months after Traumatic Brain Injury (TBI) that were collected in 18 countries. We used multiple methods to detect Differential Item Functioning (DIF) including Item Response Theory, logistic regression, and the Mantel-Haenszel method.Results: At the 6-month post-injury, 2137 (738 [34.5%] women) participants completed the PHQ-9 and GAD-7 questionnaires: 885 [41.4%] patients were primarily admitted to the Intensive Care Unit (ICU), 805 [37.7%] were admitted to hospital ward, and 447 [20.9%] were evaluated in the Emergency Room and discharged. Results supported the invariance of PHQ-9 and GAD-7 across sex, patient strata and linguistic background. For different strata three PHQ-9 items and one GAD-7 item and for different linguistic groups only two GAD-7 items were flagged as showing differences in two out of four DIF tests. However, the magnitude of the DIF effect was negligible.Limitation: Despite high number of participants from ICU, patients have mostly mild TBI.Conclusion: The findings demonstrate adequate psychometric properties for PHQ-9 and GAD-7, allowing direct multigroup comparison across sex, strata, and linguistic background.

We explore the influence of psycho-social factors including the attachment to parent and peer, self-control, and anomie on suicidality. Research questionnaires were distributed among 336 students of Shahid Chamran University of Ahvaz in Iran. The results demonstrated that mother and peer attachments had an indirect effect on suicidality via self-control and anomie, and self-control had a direct effect on suicidality and an indirect effect via anomie. Self-control and anomie had the most efficient role in the model with a large effect size. Findings are discussed theoretically and with regards to the socio-cultural sphere of Iranian society.

The purpose of the current study is to examine the relationship between socioeconomic status, parental control, and authoritarianism in Iran. A sample of 460 students was surveyed from Shahid Chamran University of Ahvaz in Iran. Results demonstrated that subjective socioeconomic status, parental control, and parents' education have significant influence on authoritarianism. Further analysis showed that parental control partially mediates parents' education association with authoritarianism with a relatively high effect size. These findings highlight the importance of parental control and socioeconomic status in the development of authoritarianism in Iran. Furthermore, the higher authoritarianism of low socioeconomic status is mostly due to lower education levels rather than the income of the family. The findings were discussed with regards to literature as well as the socio-cultural sphere of Iran. [ABSTRACT FROM AUTHOR]

Despite some scientific research on suicide as one of the most serious social and mental health problems in Iran, there is still lack of research on the effective structural and socio-familial factors contributing to the issue in Iran. The purpose of this study is to investigate some of the effective variables conditioning suicidality while also establishing a synthetic model. Three hundred-fifty university students (165 males, 185 females) were randomly chosen from Shahid Chamran University, Ahvaz, Iran. The participants were asked to complete a package of self-report questionnaires including subjective socioeconomic status (SES), feeling of anomie, perceived parental control, and suicidality. The results show that all correlations among variables are significant. For testing the theoretical model, results of standardized regression coefficients suggest that SES has direct effect on suicidality and indirect effect via anomie and parental control. In addition, parental control has direct effects on suicidality and indirect effect via anomie as well. The findings confirm the expected paths hypothesized among variables which are consistent with the theories of Durkheim, Merton, Kohn, and Agnew. It implies that the development of suicidality takes place within socioeconomic context through the influence of parental control and feeling of anomie. [ABSTRACT FROM AUTHOR]

We explored the relationship between mother, father, and peer attachment security, empathy, and moral authority in order to clarify certain problems of previous empirical research on such relationships. A sample of 202 Persian-speaking undergraduate students completed questionnaires pertaining to these constructs. The results revealed that mother and father attachment were significantly correlated with family, society welfare, and equality sources of moral authority, whereas peer attachment security was related only to society welfare and equality sources of moral authority. Out of the empathy subscales, only empathic concern was associated with moral authority sources. Empathic concern was also related to mother, father, and peer attachment, whereas perspective taking was correlated with mother and peer attachment. The combination of empathic concern and mother, father, and peer attachment predicted significant amount of variance of “principle source of moral authority” (including society welfare and equality sources). Findings support existence of a strong relationship between attachment security and the content of moral thought of adolescents, and findings redress an empirical imbalance in research literature on the relation of attachment and morality.
