059_ The impact of early life stress on global functioning, quality of life and symptomatic burden in patients from the affective-to-psychotic spectrum and healthy controls
Research Question and Aims
Evidence indicates that in addition to genetic risk factors life events do influence the risk for psychiatric disorders and their clinical severity; especially the risk for psychotic 1-3 and affective disorders 4,5 may be dependent on early life stress. Furthermore, early life stress is considered to affect social functioning and cognitive performance in healthy controls Senner et al. under review. The PsyCourse Study allows us to elaborate cross-diagnostic analyses of the influence of early life stress on global functioning (GAF) and quality of life (WHOQoL). Thus we will try to predict these parameters in a group of patients with affective and psychotic disorders and healthy controls dependent on the experience of early adverse events.
Furthermore, we want to investigate whether certain subtypes of childhood trauma (physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect) attribute to specific symptomatic constellations. In patients with FEP (first-episode-psychosis), distinct effects of childhood trauma were observed on positive and negative symptom severity, global functioning, and depression 3. Emotional and physical abuse increased certain symptom constellations in patients with bipolar disorder 6. For affective disorders, especially emotional abuse is a risk factor to the occurrence of depressive symptoms 7. A meta-analysis showed that early life stress increases the likelihood of an admixture of affective, anxiety and psychotic symptoms across diagnostic boundaries. As certain early life stress patterns are apparently associated to specific changes on a symptom level, we want to analyze this phenomenon in a cross-diagnostic group of patients with affective and psychotic disorders and healthy controls. Therefore, we will try to predict the symptom severities as measured by PANSS, YMRS and IDS-C30 given the information of the CTS. Secondly, a cluster analysis on symptom level will be performed in order to find trends concerning co-occurrences of early life stress subtypes and their association with certain symptomatic constellations.
Analytic Plan
Hypothesis
1. We hypothesize that global functioning and quality of life (measured by GAF and WHOQoL; averaged over v1-4) in patients from the affective-to-psychotic spectrum and healthy controls can be predicted dependent on the early life stress level measured by CTS across diagnostic boundaries.
2. We hypothesize that symptom levels (measured by PANSSSpos, PANSSneg PANSSgen, YMRS and IDS-C30; averaged over v1-4) in patients from the affective-to-psychotic spectrum and healthy controls can be predicted dependent on the early life stress level across diagnostic boundaries.
3. We hypothesize that clusters of symptoms (independent of the clinical-control-status and diagnosis) exist and that the occurrence of the early life stress subtypes vary among these clusters.
Participants
Data from all participants in PsyCourse who have completed the "Childhood Trauma Screener" (CTS) will be included in this study.
Analytic methods
The analyses will be performed cross-diagnostically in patients and the healthy control group.
For H1
We will perform a machine learning based prediction for investigating the impact of early life stress on GAF and WHOQoL (averaged values from v1-v4).
Dependent variables: gaf, whoqol
Independent variables: cts
Covariates: age, sex, center, diagnosis, clinical-control-status
For H2
We will perform a machine learning based prediction for investigating the impact of early life stress on symptomatic burden measured by PANSSpos, PANSSneg, PANSSgen, YMRS and IDS-C30 (averaged values from v1-v4).
Dependent variables: PANSSpos, PANSSneg, PANSSgen, YMRS, IDS-C30
Independent variables: cts
Covariates: age, sex, center, diagnosis, clinical-control-status
For H3
Clusters on symptom levels (measured by PANSS, YMRS, and IDS-C30) will be built (corrected for the clinical-control-status and diagnosis) and investigated regarding the (co-)occurrence of different trauma subtypes.
