Objective: The aim of the study is to explore the relationship between family accommodation, emotion regulation difficulties, and alexithymia in obsessive-compulsive disorder (OCD). Methods: The study group consisted of 107 individuals diagnosed with OCD, while the control group included 151 healthy individuals. Sociodemographic data form, Yale-Brown Obsessive Compulsive Scale (YBOCS), Family Accommodation Scale-Patient Version (FASPV), Toronto Alexithymia Scale (TAS), and Difficulties in Emotion Regulation Scale (DERS) were used to collect data. Results: In our study, it was found that the median DERS and TAS scores of the participants were significantly higher in the OCD group than in the control group. A moderate positive correlation was found between FAS-PV and the total score of YBOCS (p=0.002, r=0.302). Statistically significant, low to moderate, positive correlations were observed between FAS-PV and the total score of DERS (p=0.001, r=0.319). Furthermore, a statistically significant, moderate to low correlation was found between YBOCS and the total score of DERS. A positive and substantial influence on FAS-PV is provided by the YBOCS variable (B=0.571, p=0.01). Conclusion In conclusion, this study found that difficulty in emotion regulation and alexithymia levels were higher in individuals with OCD compared to healthy controls, and that family accommodation was related to both difficulties in emotion regulation and alexithymia. Finally, it was determined that difficulty in emotion regulation has a mediating effect in the relationship between family accommodation and alexithymia. It is suggested that longitudinal studies be conducted to further support the data presented by this study.

Objective: In this study, it is aimed to investigate the relationship between the oxytocin level and the rejection sensitivity, childhood mental traumas, and attachment styles in patients diagnosed with borderline personality disorder (BPD). Methods: Participants between the ages of 18–30 were included in the study. The patient group consists of 31 participants and the healthy control group consists of 31 participants. Sociodemographic/Clinical Variables Questionnaire, Relationship Scales Questionnaire, Rejection Sensitivity Questionnaire and Childhood Trauma Questionnaire were administered to the participants included in the study. Serum oxytocin levels of the participants were measured using the Elisa method. Results: The oxytocin levels were found to be significantly lower in patients with BPD than in healthy control subjects, whereas the rejection sensitivity and childhood traumas were found to be significantly higher. No difference was found between the patient and control groups in terms of attachment styles, yet it was determined that there may be differences between the oxytocin levels of the BPD patients according to the attachment styles the patients have. Conclusion In conclusion, the findings of this study revealed that the rejection sensitivity in BPD patients is not associated with oxytocin levels and childhood traumas, indicating the need to assess the BPD patients in terms of other biopsychosocial factors related to the etiopathogenesis of BPD.
