Childhood emotional trauma and cyberbullying perpetration among emerging adults: a multiple mediation model of the role of problematic social media use and psychopathology

Research suggests that a small minority of social media users experience problems as a result of their online use. The purpose of the present study was to examine the association of cyberbullying perpetration and problematic social media use with childhood emotional trauma, Cluster B (narcissistic, histrionic, antisocial, and borderline) personality traits, dissociative experiences (DEs), depression, and self-esteem in a nonclinical undergraduate sample. A total of 344 university students volunteered to complete a questionnaire that included measures on the aforementioned dimensions. Thirty-eight percent of the participants had emotional neglect and 27% had emotional abuse, while 44% of them demonstrated at least one cyberbullying perpetration behavior. Results indicated that cyberbullying perpetrators had higher scores on problematic social media use, dissociative experiences, Cluster B traits, depression and childhood emotional trauma, and lower on self-esteem. Path analysis demonstrated that, while adjusting for gender and age, childhood emotional trauma was directly and indirectly associated with cyberbullying perpetration via Cluster B traits. Moreover, depression and dissociation were directly associated with problematic social media use. The findings of this study emphasize the important direct role of childhood emotional trauma and pathological personality traits on cyberbullying perpetration

Development and validation of the Online Histrionic Personality Scale (OHPS) using the DSM-5 criteria for Histrionic Personality Disorder

The present study evaluated personality presentation in online environments in terms of histrionic personality. The aim of the study was to develop the Online Histrionic Personality Scale (OHPS). The OHPS was developed using the diagnostic criteria for histrionic personality disorder (HPD) in the DSM-5 and assesses histrionic behavior in online environments. The present study comprised 381 university students (219 females and 162 males) from four different samples. The validity of the OHPS was investigated utilizing exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and criterion validity. As a result of the EFA, a single-factor structure with an eigenvalue of 3.850 was found and accounted for 48.12% of the total variance. This one-dimensional structure was tested with CFA in two different samples. CFA results show that OHPS had an acceptable fit. The criterion validity of the OHPS was examined with the Desire for Being Liked Scale (DBLS) and the Histrionic Personality Belief subscale of the Personality Belief Questionnaire-Short Form (PBQ-STF). Analysis showed that the OHPS was significantly associated with desire for being liked (r = .65, p < .01) and histrionic personality beliefs (r = .70, p < .01). The reliability of the OHPS was evaluated with Cronbach’s α internal consistency reliability coefficient and corrected item total correlation coefficient in three different samples. The Cronbach α internal consistency coefficients of the OHPS were .84 (EFA sample), .88 (CFA sample), and .88 (criterion validity sample). Corrected item total correlation coefficients of OHPS ranged from .53 to .62 in the EFA sample, .47 to .78 in the CFA sample, and .52 to .76 in the criterion validity sample. The distribution of data was examined with floor and ceiling effects in three different samples. Finally, the standard error of measurement (SEM) was calculated in three different samples. There were no floor and ceiling effects in the data, and the SEM values were within acceptable limits. When validity and reliability analyses of the OHPS are considered as a whole, it is concluded that the OHPS is a valid and reliable scale that assesses online histrionic personality among university students

İrritabl barsak sendromlu hastalarin aleksitimi, mizaç, karakter özellikleri ve psikiyatrik tani açisindan değerlendirilmesi

Objective: It is well documented that there is a strong relationship with Irritable Bowel Syndrome (IBS) and stress. Indeed IBS is a psychosomatic disease of gastrointestinal system. In this study it is aimed to determine the anxiety and alexithymia levels and their association with temperament, and personality in both patient and healthy control groups. Method: Thirty-four patients with IBS according to Roma II Diagnostic Criteria and 32 healthy volunteers were included in the study. Patients with IBS and the healthy subjects were evaluated by DSM-IV diagnostic criteria, Temperament and Character Inventory (TCI), State and Trait Anxiety Inventory-II (STAI-II) and Toronto Alexithymia Scale-26 (TAS-26) have been applied. Results: Mean age of patients with IBS was 36.41±8.5 and average period of the illness was 6.65±5.8 years. 76.5% of IBS patients had at least one DSM-IV diagnoses. In IBS patient group, mean STAI-II score were significantly higher than the control group (p=0.001 and p=0.007, respectively). Among TCI subscales harm avoidance (HA) and self-transcendence (ST) mean score were significantly higher in IBS patient group than healthy controls (p=0.023 and p=0.039, respectively). The result of backward condition logistic regression analysis of total HA and total ST points in the sixth step were found to be a significant predictors of IBS's existence (in the sixth step it was found that 2 log likelihood: 80.615 and R 2=0.181). Conclusion: With respect to these psychiatric disorders or temperamental and characteristic properties they can have a role in occurrence and exacerbation of IBS
