Literature reports gender differences on emotional maltreatment and the experience of PTSD, so it is worth investigating the existence of differences when looking at separate symptoms. Objective: This study aims to investigate the correlation between childhood emotional maltreatment and PTSD symptomatology and identify gender differences in children and adolescents. Method: A sample of 237 children (mean age 15.5) with PTSD symptoms from a Dutch mental health institution (2012-2015) underwent assessment using anonymous questionnaires. Network analysis examined partial correlations between emotional abuse, neglect, intrusions, avoidance, arousal, and negative mood. Results: The network analysis showed a high correlation between emotional abuse and most PTSD symptoms. However, emotional neglect only exhibited a strong association with emotional abuse. Gender differences in how emotional maltreatment and PTSD symptoms interacted were found. Girls reported higher PTSD symptoms and emotional maltreatment than boys. Conclusions: This study highlights the important role of childhood emotional maltreatment in the development of PTSD, among children and adolescents. These results emphasize the need for the customization of PTSD treatment based on the type of maltreatment and gender.Show less

Previous studies have established that a long delay occurs between the onset of mood symptoms in BD and the first form of treatment received, estimates ranging between 6 and 11 years. Cognitive impairments in the domains of executive functions, processing speed and memory were found to persist in BD patients even during euthymia. Such cognitive impairments burden BD patients, prevent them from regaining an appropriate level of general functioning and diminish their quality of life. Thus, in order to determine whether treatment delay impacts the cognitive impairments present in BD, 69 participants were followed over the course of one year, at three different time points. The participants took part in clinical interviews, and then were asked to complete multiple measures, such as the YMRS, the QIDS, four WAIS subscales (Block Design, Arithmetic, Information and Digit symbol), and the Cognition subscale of the WHODAS. The average treatment delay found in the current sample was 14.53 years. The results of the current study suggest that longer treatment delays did not significantly predict worse cognitive functioning in BD patients, either when measured subjectively, or when measured objectively.Show less

Negative self-conscious emotions, such as shame and guilt, may be related to this relationship. In this study the relationship between suicidal ideation and borderline personality traits was explored. Shame and guilt were analysed as possible mediators. The Personality Assessment Inventory – Borderline Scale was used to assess borderline personality traits, and Ecological Momentary Assessment was used to gather data on suicidal ideation, guilt and shame four times a day, over the course of three weeks via an app. The sample consisted of (N = 82) adults with a history of a suicide attempt or moderate-to-severe suicidal ideation in the past year. The relationships were analysed using a parallel mediation model consisting of multiple multilevel regression analyses. All steps of the model showed significant relationships. The last step showed that instead of typical mediation, the model indicated suppression, because of an increase in the association between borderline personality traits and suicidal ideation when accounting for shame and guilt. More research is necessary to explore the possible cause of these findings.Show less

This study explores the association of self- views, positive emotions, and social connections in the context of social media, particularly regarding #selflove and in AOD recovery. Specifically, social connections are examined as they are considered to be a relevant point of support during the recovery process. Positive emotions are examined, as employing a more positive outlook towards oneself is associated with a more positive self-view and a more sustained recovery process. The dataset comprises 902 posts from Instagram and Twitter in 2019 collected by Ziemer (2022). The present study addresses two research questions: (1) What is the association between positive and negative self-views in social media posts using chi-square analysis to identify a balanced self-view (discussing negative and positive self-views) during the recovery journey, (2) to what extent can positive self-view mentions be predicted through logistic regression, based on expressed connectedness with family/friends, the AOD recovery community, and positive emotions in the posts. Surprisingly, the results challenge the initial hypothesis of predominantly balanced self-views in these posts, as no association was found between mentioning positive and negative self-views within a single post. Contrary to expectations, mentioning positive self- views was not linked to references to connecting with others or positive emotions. Future research should employ more nuanced coding for emotions and social connections. Qualitative measures can help capture potential differences between sharing one's recovery journey online and the actual offline experience.Show less

Several factors have been identified that are associated with a low QoL and high health costs in individuals diagnosed with a PD. The influence of trauma is unknown. It has been found that PDs are associated with both past trauma experiences and symptoms of posttraumatic stress disorder (PTSD) in their daily life. While several studies suggested that individuals with a Borderline PD (BPD) and comorbid PTSD suffer from a more impaired QoL compared to individuals with a single disorder, less is known about the effect of PTSD on PDs other than BPD and the relation between trauma severity and health costs. The current study investigates the effect of both childhood trauma and current PTSD symptoms on QoL and health costs in individuals diagnosed with a PD and the possible mediating role of QoL on the relationship between trauma and health costs. The sample consisted of 65 individuals, with a mean age of 38 (SD = 12.3), diagnosed with one or more PDs. Data was collected with several questionnaires (Childhood Trauma Questionnaire-Short Form, Posttraumatic Stress Disorder Checklist for DSM-5, Treatment Inventory of Costs in Patients with psychiatric disorders, and the Mental Health Quality of Life questionnaire). The results show that severity of current PTSD symptoms (t(58) = -4.19, p < .001) but not childhood trauma was related to a decreased QoL in individuals diagnosed with a PD. Both current PTSD symptoms and childhood trauma were not significantly related to health costs. QoL did not perform a mediating role on the relationship between trauma and health costs. To conclude, severe PTSD symptoms represent an additional deprivation for QoL among personality-disordered individuals in this sample. This conclusion is based on a relatively small sample, thus should be further investigated with a larger sample.Show less

Trauma symptoms or PTSD can lead to significant disruptions in cognitive empathy and high levels of anxiety. The aim of the current study is to look into the relationships between PTSD, cognitive empathy and anxiety in Syrian refugee children, and to test for gender differences. Participants were 33 Syrian refugee children aged 10-18. PTSD was measured using CPSS, cognitive empathy was measured using the EmQue-CA and the EDG (three social conditions were used: neutral individuals, victims and offenders of intentional pain) and anxiety was measured using the SCARED. Results showed that cognitive empathy did not affect Syrian refugee children in social situations. Secondly, anxiety did not affect cognitive empathy levels. Thirdly, anxiety did not affect cognitive empathy differently for boys and girls. Lastly, cognitive empathy is disrupted within Syrian refugee children with trauma symptoms or even PTSD. Suggesting that cognitive empathy is a predictor of PTSD. The findings of the current study could potentially be important for future faster treatment of trauma symptoms or even PTSD by using cognitive empathy levels as a predictive factor.Show less

However, there is a lack of research exploring adult attachment styles as a mediator between bullying victimization in childhood and adult depressive and anxious symptoms. The present study investigated if the relationship between bullying victimization before the age of 18 and anxious and depressive symptoms in university students is mediated by adult attachment styles. Participants were part of a larger survey study of the Caring Universities Project. The sample included 3388 participants (university students) between the ages of 18 to 36, who filled out an online questionnaire testing for bullying victimization (RBQ), anxious symptoms (GAD-7), depressive symptoms (PHQ-9), and adult attachment styles (RQ). It was hypothesized that the relationship between bullying victimization and mental health is mediated by insecure attachment styles. A partially mediating effect of fearful and preoccupied attachment styles on the association between bullying victimization and anxious and depressive symptoms was established. A reason for the mediation effect of these two insecure attachment styles might be the underlying negative concept of the self that these attachment styles have in common. Limitations and implications of the findings are discussed.Show less

Research on potential correlations and moderators is relevant to gain further insight into the networks involved in the gut-brain axis. The findings can influence treatment approaches in the field of clinical psychology to a greater focus on the gutbrain axis. Two hypotheses were examined: 1) a higher microdiversity in the gut is correlated with less emotion regulation difficulties, and 2) there are sex differences in the correlation between microdiversity and emotion regulation. Methods: This research was an observational between-subjects design with a total number of 75 participants. The primary outcome was the alpha score, assessed with the Shannon Index, which gives insight into individual microdiversity. The Difficulties in Emotion Regulation Scale was used to assess self-reported difficulties in emotion regulation to have insight into individual cognitive reactivity. Sex was conceptualised as the moderator variable. A correlational analysis for alpha scores and DERS scores was carried out, followed by a multiple regression analysis, which tested for a moderation with the variable sex. Results: There was no evidence for a negative correlation between high microdiversity and few emotion regulation difficulties. Sex did not have a significant moderation on this correlation either. Implications: Further research is needed on the gut-brain axis and sex differences in gut microdiversity and emotion regulation to adapt the treatment of stress-related disorders such as post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), or other anxiety-related disorders from a cognitive- to a more holistic approach.Show less

This cognitive enhancer exerts its effects by binding to the dopamine transporter, resulting in heightened extracellular dopamine levels. However, the psychophysiological side-effects associated with this medication are not yet fully understood. The present study delves deeper into erratic psychophysiological side-effects, including psychosis, mood changes, experiences of seizures, tics and the development of skin rashes. Our primary objectives were twofold. Firstly, we aimed at exploring the frequency of adverse symptom perception in individuals receiving methylphenidate as treatment. Secondly, we sought to investigate the potential impact of treatment duration on symptom perception, and examine any potential correlation between the two. To achieve this, we implemented an online version of ‘The Methylphenidate monitoring side effects scale’ (MMSES), with a total of 135 participants, 22 belonging to the experimental group, with prescribed medication, and 113 to the control group, not receiving medication. The results of our study revealed that adverse symptom perception did not significantly differ between the experimental and the control group, (t = 0.31, p = .852). However, psychotic symptoms were significantly lower in the control group in comparison to the experimental group (t = 0.56, p = .041). Additionally, the correlational analysis demonstrated a non-significant relationship between treatment duration and symptom perception (r(20) = .21, p = .353). These preliminary findings need to be followed up by future research and require to be interpreted with caution due to a possibly confounding effect of age differences and other limitations. Future directions may comprise the inclusion of neuroimaging techniques to identify the pathophysiological changes associated with methylphenidate administration, and a larger sample size.Show less

There was a sample of 115 adolescents, and their parents (n = 214), including a group of depressed and a group of healthy control adolescents. Each adolescent was asked to write down two stressful events from his/her past and code the intensity of these events. After that, they were asked to discuss these events with their parents, and answer to three questions of the Parental Bonding (PB) questionnaire. Researchers also coded the intensity of the events. For our first hypothesis we conducted a multiple regression analysis to investigate whether depression constitutes a moderator variable between the adolescents’ codes of intensity towards their events and the researchers’ codes. For the second hypothesis we ran one-way ANCOVA to examine if there were any differences between the two groups in PB answers. Depression did not seem to moderate the relationship between the adolescents’ and the researchers’ intensity codes. However, separately, the researchers’ codes and the condition of the adolescents, depressed or not, proved to have statistically significant and positive main effects on the way the adolescents experienced their events. At the same time, the two groups also exhibited statistically significant differences on the PB. Considering these results, it is imperative to highlight the importance of including familial factors and the cultivation of resilience and coping skills towards stress into the intervention and prevention programs that address the adolescent depression.Show less
