Links between personality functioning and post-traumatic stress disorder symptoms: a network analysis.
The study finds a significant link between personality functioning and PTSD symptoms, suggesting that addressing negative self-perception and interpersonal issues may help in managing PTSD.
Where it sits
this study against the rest of the eloralintide corpusSummary and findings
The study examines the relationship between personality functioning and post-traumatic stress disorder symptoms in a sample of 1899 patients. A robust conditional association was found with an effect size of 0.31. The analysis also identified specific subdomains of personality functioning that directly link to PTSD symptoms.
Abstract
<b>Background:</b> The study investigates the association between personality functioning (PF) and post-traumatic stress disorder (PTSD) symptoms in a large naturalistic clinical sample using a network analytical approach.<b>Objectives:</b> It aims to determine whether the previously observed link between PF and PTSD persists after controlling for frequent comorbidities (depression, anxiety and somatic symptoms), and to identify bridges connecting both clinical constructs.<b>Methods:</b> A regularised partial correlation network between PF, PTSD, as well as depression, anxiety and somatic symptoms was estimated at the total scale, subdomain and item level. For this aim, data from the Multicenter Effectiveness Study of Inpatient Psychosomatic Psychotherapeutic Treatment (MEPP) were reanalysed, comprising an overall <i>N</i> = 1899 patients (Age: <i>M</i> = 39.73y, SD = 14.11, range = 18-84; female = 69%).<b>Results:</b> A robust conditional association between PF and PTSD (<i>E</i> = .31) was observed. Among PF subdomains, self-perception (<i>E</i> = .18), and relationship model (<i>E</i> = .21) showed direct links to PTSD. Symptom-level analysis identified negative beliefs (PTSD) and self-esteem, interpersonal distrust and affective dysregulation (PF) as the central bridge nodes connecting both constructs.<b>Conclusions:</b> The relationship between personality functioning and PTSD is specific and distinct from general distress. A treatment focus on negative self-perception, interpersonal (dis)trust and affective regulation might be a promising pathway for symptom reduction, specifically in patients with comorbid PTSD and PF impairments.<b>Trial registration:</b> German Clinical Trials Register identifier: DRKS00016412..
Background
This study investigates the relationship between personality functioning (PF) and post-traumatic stress disorder (PTSD) symptoms, building on previous findings that suggest a link between these constructs. Prior research has indicated that personality traits may influence the severity and manifestation of PTSD symptoms. Understanding this relationship is crucial for developing targeted interventions, especially in clinical settings where comorbidities such as depression and anxiety are prevalent.
Methods
The study utilized a network analytical approach to estimate a regularised partial correlation network among PF, PTSD, depression, anxiety, and somatic symptoms. Data were reanalyzed from the Multicenter Effectiveness Study of Inpatient Psychosomatic Psychotherapeutic Treatment (MEPP), involving a total sample size of 1899 patients. The analysis was conducted at the total scale, subdomain, and item level, focusing on both primary and secondary outcome measures.
Results
A robust conditional association between personality functioning and PTSD was observed, with an effect size of E=0.31. Specific subdomains of personality functioning, including self-perception (E=0.18) and relationship model (E=0.21), were found to have direct links to PTSD symptoms. The symptom-level analysis highlighted negative beliefs related to PTSD and several PF factors, including self-esteem and interpersonal distrust, as central bridge nodes connecting the two constructs.
Interpretation
The findings suggest a specific and distinct relationship between personality functioning and PTSD, which is not merely a reflection of general distress. While the effect sizes are statistically significant, their clinical relevance may be limited, particularly given the complexity of PTSD and its comorbidities. The study's observational nature and reliance on self-reported data may introduce confounding factors that limit the generalizability of the results.
