Intimate Partner Violence and Alexithymia: Do Emotions Matter? A Systematic Review and Meta-Analysis

The aporetic dialogues of Modena on gender differences: Is it all about testosterone? EPISODE I: CRIME

This is the first episode of a series of four discussions on the differences between males and females, in apparently non-andrological fields. You will read the transcript of discussions that actually took place at the Endocrinology Unit in Modena, Italy, in the form of the aporetic dialogues of ancient Greece. In this episode, the role of testosterone in gender differences in criminal behavior will be explored. The discussants were divided into two groups: group 1, which supports the thesis of a predominant role of testosterone, and group 2, which opposes it. The first group affirmed that both endogenous testosterone and anabolic-androgenic steroids could trigger aggressive and criminal behavior, regardless of predisposition to psychiatric disease or sociocultural background. The second group asserted the multifactorial genesis of aggressive and criminal behavior, citing other hormonal and non-hormonal factors, such as neurotransmitters, cortisol, and sociological and psychological aspects. In the end, a forensic physician, acting as a referee, tried to resolve the aporia: are the two theories equivalent or one is superior?

Attitudes Toward Dating Violence, Social Impact, and Alexithymia in University Students: A Structural Equation Modeling

This research was conducted to determine the effects of social impact and alexithymia on attitudes toward dating violence. Additionally, the interaction between them was examined. In this context, the effect of social impact on alexithymia was also examined. In addition, this research tried to determine whether alexithymia has a mediating role between social impact and attitudes toward dating violence. The study was descriptive and cross-sectional. There was a total of 582 participants in the study. The study used the Sociodemographic Questionnaire Form, Social Impact Scale (SIS), 20-Item Toronto Alexithymia Scale (TAS-20), and Dating Violence Scale (DVS) for data collection. The study used the descriptive statistics, spearman correlation analysis and structural equation modeling in the evaluation of the data. Participants' SIS scores had a statistically significant and positive correlation with their TAS-20 scores (p < .01), while they had a statistically significant and negative correlation with their DVS scores (p < .01). In addition, a statistically significant and negative correlation was found between TAS-20 scores and DVS scores (p < .01). SIS scores directly affected the TAS-20 (effect value = 0.481; p = .001) and DVS scores (effect value = -0.405; p = .001). Similarly, the TAS-20 scores had a direct effect on the DVS scores (effect value = -0.261; p = .008). In addition to this direct effect of TAS-20 scores, there was a significant mediator effect between the SIS scores and DVS scores (effect value = -0.126; p = .008). In this study, it was established that social impact effects both alexithymia and attitudes toward dating violence, and moreover, alexithymia influences attitudes toward dating violence. Additionally, it was identified that alexithymia serves as a mediator in the relationship between social impact and attitudes toward dating violence.

Investigating the role of alexithymia in the association between cumulative childhood maltreatment and teen dating violence victimization

BACKGROUND

Childhood maltreatment is increasingly recognized as an important risk factor for teen dating violence (TDV) victimization. However, far too little research has studied the mechanisms that could explain this higher risk of revictimization. The present study investigated the role of alexithymia in the association between cumulative childhood maltreatment, TDV victimization occurrence and chronicity, and TDV-related post-traumatic stress disorder (PTSD) symptoms.

METHODS

A total of 2780 adolescents, aged 13 to 19, completed measures of childhood maltreatment and alexithymia at Time 1 and TDV victimization and TDV-related PTSD symptoms at Time 2 (6 months later). Two mediational models were tested to examine the role of alexithymia as a risk factor for revictimization. One model assessed TDV occurrence as an outcome, while the other explored TDV chronicity and TDV-related PTSD symptoms as outcomes.

RESULTS

Findings suggest that cumulative childhood maltreatment is associated with an increased probability of TDV occurrence through alexithymia. Cumulative childhood maltreatment and alexithymia are also associated with TDV chronicity and TDV-related PTSD symptoms. Notably, cumulative childhood maltreatment is associated with higher levels of alexithymia among adolescent victims of TDV, which, in turn, predicts higher TDV chronicity and TDV-related PTSD symptoms.

LIMITATIONS

This study relied on abbreviated measures and did not include all forms of child maltreatment (e.g., emotional and physical neglect).

CONCLUSIONS

Promoting emotional awareness and identification among youth victims of child maltreatment could reduce the risk of TDV occurrence, TDV chronicity, and TDV-related PTSD symptoms.
