Uit onderzoek blijkt dat opvoedstijl een voorspeller kan zijn voor de hoeveelheid angstklachten bij adolescenten. Met name een (over)beschermende opvoedstijl zou samenhangen met angstklachten bij de adolescent. Maar welke aspecten van deze opvoedstijl leiden tot verhoging van angstklachten is nog niet volledig bekend. Bij een (over)beschermende opvoedstijl ligt de nadruk wellicht minder op het aspect cognitieve empathie. Als ouders heel beschermend zijn, zijn ze zich mogelijk minder bewust van de gevoelens en behoeftes van hun kind. Ouders proberen de emoties van het kind te controleren en tonen zo minder empathie, door minder ruimte voor emoties te geven. In de huidige studie is daarom onderzocht of verhoogde cognitieve empathie het verband tussen een (over)beschermende opvoedstijl en angstklachten bij adolescenten medieert. Hiertoe hebben 115 adolescenten, waarbij 102 vaders en 114 moeders, als onderdeel van een grotere studie, een reeks vragenlijsten ingevuld om deze variabelen te meten. Met de Interpersonal Reactivity Index werd cognitieve empathie van de ouders gemeten, met de Screen for Child Anxiety Related Emotional Disorders de angstklachten bij de adolescent en met de Parental Bonding Instrument de mate van een (over)beschermende opvoedstijl. Regressieanalyses toonden aan dat een (over)beschermende opvoedstijl van de ouders inderdaad positief samenhing met de angstklachten bij de adolescent, maar deze relatie werd niet gemedieerd door cognitieve ouderlijke empathie. De resultaten worden geïnterpreteerd en limitaties en vervolgonderzoeken worden besproken.Show less

A similar relationship between aggressive behavior and the immune system suggests that the three phenomena are interconnected in some way. To date, this interaction has not been researched in adolescents. The current study investigates the relationship between adolescent depression and immune markers (IL-6, IL-1β, TNF-α and CRP), and examines aggressive behavior as a potential moderator in this relationship. Immune markers were measured in salivary samples, contributing to the incorporation of a novel, non- invasive way to assess inflammation in mental health research. Methods: A total of 114 adolescents with and without clinically diagnosed depression were included in the present study (32 depressed, 76 healthy controls; 32.4% males; mean age 15.91 years old, ranging from 12-18). Participants provided 2ml saliva via passive drool, in which IL6, IL-1β and TNF-α were analyzed with the Luminex Human Discovery Assay (Bio-Techne), and CRP was analyzed with an ELISA Kit Generation II (Salimetrics). Parents of the participating adolescents filled in the Child Behavior Checklist-questionnaire on aggressive behavior. Results: In an analysis of covariance no significant associations were found between depression and levels of IL-6, IL-1β, TNF-α and CRP. In addition, no significant moderating effects of aggressive behavior on this relationship were found. Conclusion: Despite earlier evidence nudging towards a relationship between depression and the immune system, this study has not obtained similar results. Future studies on the matter are warranted, preferably with simultaneous advancement of salivary measurement technologies.Show less

Veranderingen in het empathievermogen van ouders kunnen dan ook grote gevolgen hebben voor de ontwikkeling van het kind. Wanneer ouders een verleden hebben met jeugdtrauma gerelateerd aan kindermishandeling, kan dat hun empathievermogen veranderen. Om een beter beeld hiervan te krijgen in de opvoedcontext, werd er onderzocht of ouders met een verleden met jeugdtrauma negatievere emoties ervaren als reactie op een nare gebeurtenis van hun kind en of dit verband gemedieerd werd door empathie. De steekproef bestond uit 115 adolescenten, waarvan 35 met een depressieve stoornis en 80 gezonde adolescenten. Eén of beide ouders van de adolescenten namen ook deel (n = 120 moeders, n = 108 vaders). Er werd een interactietaak afgenomen waarbij het kind een nare gebeurtenis met de ouder deelde en er werden vragenlijsten afgenomen die empathie en negatieve emoties maten. In dit onderzoek is er alleen gekeken naar de data van de ouders. Er werd een significant positief verband gevonden tussen jeugdtrauma en negatieve emoties in reactie op een nare gebeurtenis van het kind, β = 0.30, p < .001. Dit verband werd in tegenstelling tot de verwachting niet gemedieerd door empathie. Deze bevindingen hebben mogelijk belangrijke implicaties voor de praktijk en vervolgonderzoek. Zo kan het bijvoorbeeld bijdragen aan het ontwikkelen van hulpmiddelen voor ouders met een traumaverleden en aan de verbreding van het perspectief op jeugdtrauma en empathie. Dit is belangrijk om de negatieve gevolgen op de emotieregulatie van het kind te beperken.Show less

There is still little evidence-based research done on the effects of peer support for people with symptoms of PTSD that have experienced domestic violence. Consequently, it is of great clinical interest to investigate if peer support groups are beneficial for this subgroup. This study investigated whether peer support groups are an effective treatment for reducing PTSD symptoms by increasing hopefulness among women who have experienced abuse. Thirteen female participants (Mage = 37.54 years at baseline) attended ten sessions of peer support groups led by an experience expert and completed questionnaires at a pre-measurement and a post-measurement. The methods used in this study were the Life Events Checklist, PTSD checklist for DSM-5, adult hope scale, and childhood trauma questionnaire. We found a reduction in the severity of PTSD symptoms (for intrusion symptoms and negative changes in cognitions and mood) and an increase in hopefulness after participation in the peer support sessions. This increase was seen for both participants' goal orientation and their ability to make plans to achieve their goals. Although we expected a relationship between PTSD symptomology and hopefulness, this was not found. The findings from this study suggest that peer support groups may be a beneficial addition for women with PTSD symptoms who are not in treatment (yet) or have tried established PTSD treatment.Show less

Attachment styles (AS) conceptualize stable behavioral patterns in response to stress and can predict long-term susceptibility to mental illness. This study investigates the relationship between 1-year-old infants’ AS, their hormonal stress response in terms of cortisol reactivity (CR) - both assessed in the course of the Strange Situation procedure - and the influence of these factors on children’s scores on the Child Behavior Checklist’s internalizing behavior problem scale (CBCL-I) five years later. Based on previous research, CR was expected to be higher with insecure compared to secure AS. Insecure AS and higher CR in infancy were expected to be associated with higher CBCL-I scores in later childhood. CR was hypothesized to partly mediate the relationship between AS and CBCL-I. Relevant longitudinal data (n=220; 40.8% female, 51.7% male) were drawn from a sample of mother-child dyads (“BIBO” research project). No evidence for any of the hypotheses could be found, as the analyses yielded no statistically significant associations between AS and CBCL-I scores, AS and CR, or CR and CBCL-I. Consequently, testing for CR’s potential mediating role was deemed irrelevant. The results contradict previous findings and raise important questions. The study’s limitations are discussed and suggestions are derived to inform future research on stress pathways in the pathogenesis of mental disorder. Above all, the poorly understood role of potentially decisive covariates in the interplay between AS, CR, and internalizing behavior need to be investigated more thoroughly.Show less

Literature suggests that the strength of this relation may be impacted by the amount of experiential avoidance individuals use. This study aims to examine the relation between interpersonal trauma and depressive feelings and the impact of experiential avoidance on this relation. This was investigated by means of online self-report questionnaires performed by 27 females with an average age of 46.26 (SD = 11.85). To measure whether participants experienced interpersonal trauma the Life Events Checklist for DSM-5 was administered. Depression scores were assessed by means of the Patient Health Questionnaire-9. Experiential avoidance was measured with the Acceptance and Action Questionnaire- II. Linear and multiple regression analyses were performed, and indicated that females who experienced interpersonal trauma score significantly higher on depression than females who did not experience interpersonal trauma (p = .008, R 2 = .25). Findings of the multiple regression analysis indicate no significant interaction of interpersonal trauma and experiential avoidance (p = .614). However, experiential avoidance by itself was a significant predictor of depression (p =<0.01) and reduced the explanatory variance of interpersonal trauma. This possibly indicates a mediating effect of experiential avoidance on the relationship between interpersonal trauma and depression. Recommendations for future research is to investigate this possible mediating role of experiential avoidance on the relation between interpersonal trauma and depression. The current findings suggest that treatments 5 targeting greater experiential acceptance, possibly through peer support groups, might help victims of interpersonal trauma.Show less

Close social relationships might buffer against the negative consequences of stress, such as childhood maltreatment, on immune function. Research objective: This study aimed at investigating the association between childhood maltreatment and adult inflammation and the role of loneliness and social support as potential moderators in this relationship. Methods: Data from the 3G study (Buisman et al., 2020) with a multi-informant multigeneration cross-sectional design was used. In total, a sample of 113 adult individuals who provided saliva samples for IL-6, IL-8, TNF-⍺, and IFN- analyses and completed self-report questionnaires about loneliness, social support, and experienced childhood maltreatment in the first 18 years of life was included in the analyses. Results: Childhood maltreatment did not predict the inflammatory markers IL-6, IL-8, TNF-⍺, and IFN-. Further, loneliness and social support did not moderate the relationship between childhood maltreatment and adult inflammation. Conclusion: Future research is needed to investigate the role of social support and loneliness as potential moderators in the association between childhood maltreatment and adult inflammation. Several implications for future research are discussed that will help to establish interventions that aim at reducing the risks for poorer health in adults with a history of childhood maltreatment.Show less

The presence of PEs alone can lead to mental distress; additionally its persistence can have grave consequences for the child’s development. Neighborhood characteristics are a promising new frontier for research on the development of PEs in childhood and adolescence. The main aim of this study was to investigate the relationship between neighborhood social cohesion, living conditions, objective and perceived safety, and PEs at age 14. The secondary aim was to investigate the relationship of the aforementioned neighborhood factors with the trajectory of PEs from age 10 to 14. We ran a specificity analysis using depressive symptoms to evaluate whether the associations were indicative of a link with general psychopathology or specific psychotic spectrum outcomes. We used the Generation R cohort data on self-reported hallucinations and delusions, and the Wijkprofiel Rotterdam on social, safety, and physical characteristics of the neighborhood. In our multilevel logistic regression analysis, we found no evidence for an association of any neighborhood factors with PEs at age 14. There were trends demonstrating the potential association between living conditions and two outcomes: remission of PEs at age 14, and severe depressive symptoms. However, neither association survived multiple testing correction. We discuss the need for further research to ascertain whether the associations apply to general psychopathology or psychotic spectrum outcomes. Furthermore, we propose the need to clarify new potential associations of neighborhood factors with PEs.Show less

Elevated levels of inflammation markers can impair brain functioning and development, which can in turn increase the risk for psychopathology. Hence, inflammation might be one of the potential mechanisms explaining the link between CM and adult psychopathology. Objective: This study aimed to investigate whether inflammation might mediate the relationship between CM and internalizing psychopathology in adulthood. Additionally, the study aimed to determine whether this effect is specific to one or more subtypes of CM. Methods: A total of 116 adults participated in the study. CM was assessed using a combination of two questionnaires: the Parent-Child Conflict Tactics Scales (CTS-PC) and the Childhood Trauma Questionnaire (CTQ). Participants’ saliva samples were analysed for three pro-inflammatory cytokines (IL-6, IL-1β, TNF-α). The Internalizing Problems subscale from the Adult Self Report (ASR) questionnaire was used to determine internalizing psychopathology. Parallel mediation analyses were conducted to test the hypotheses. Results: Experienced childhood abuse and neglect both significantly predicted internalizing symptoms in adulthood. However, the associations were not mediated by pro-inflammatory cytokines. Conclusions: This study’s findings add to the extensive body of literature showing the longterm effects of CM on internalizing psychopathologies. Contrary to expectations, the mediation effect of inflammation in this relationship was not identified. As several methodological factors could have influenced the results, this outcome should not be considered as a firm disconfirmation of the mediation hypothesis. Further prospective studies addressing this question are warranted.Show less

Empathy belongs to one of these fundamental skills. The current study aims to replicate previous findings that childhood maltreatment history is associated with lower empathy levels. Generally, research distinguishes between affective and cognitive empathy. Hence, this study explores possible differences in impact of child maltreatment history on cognitive versus affective empathy. METHOD: This cross-sectional design involved 218 healthy participants between 18 and 79 years of age. To assess child maltreatment, the Dutch version of the Childhood Trauma Questionnaire (CTQ) was used. The Interpersonal Reactivity Index (IRI) and the Multifaceted Empathy Test (MET) were used to assess both cognitive and affective empathy. The sample was divided into maltreated and non-maltreated participants, by applying cut-off scores, and where compared with multivariate ANOVAs on MET mean arousal level, MET total accuracy, perspective taking (PT), empathic concern (EC), fantasy (FS) and personal distress (PD). RESULTS: The present study failed to replicate previous findings of associations between child maltreatment and lowered empathy. Furthermore, a difference in impact on the two forms of empathy was not identified. However, after the exclusion of outliers, an indication was found for impaired cognitive empathy in individuals with maltreatment history. DISCUSSION: The present study shows that possible selective effects of child maltreatment on either cognitive or affective empathy may exist. Knowing how maltreatment differentially affects individuals in later adulthood, can help to optimize both prevention measures as well as treatments dealing with the consequence of child maltreatment, e.g. individual training focusing on either type of empathy. Limitations of the present study are discussed.Show less

Maternal prenatal stress symptoms as well as high cortisol levels have been found to predict negative affectivity in infant temperament. The current paper examined whether maternal prenatal cortisol decline during the day in late pregnancy mediates the relationship between maternal prenatal anxiety and negative affectivity in infant temperament at age 1. METHOD: This longitudinal correlational study included 114 mother-child pairs. Anxiety was assessed once in the last trimester of pregnancy and three months after giving birth. Salivary samples were taken five times a day for two days in the third trimester to determine cortisol concentrations. Infant temperament was assessed by a questionnaire answered by the mothers at infant's age 1. Maternal postnatal anxiety, birth weight and infant's gender were examined as possible covariates. RESULTS: Results revealed that there is a significant correlation between maternal prenatal anxiety and negative affectivity in infants (p < .05). No mediation effect of cortisol decline on the relationship between high scores in maternal prenatal anxiety and higher negative affectivity in infants was found. DISCUSSION: It was not clear whether adverse behavioural developments were dependent on maternal prenatal patterns and thus, whether infants could be prone to anxiety issues in later life. The study provided a framework for future studies to assess pathology's aetiology in a transgenerational way. Alternative explanations, limitations and future directions were discussed.Show less
