Assessment tools for complex post traumatic stress disorder: a systematic review

Posttraumatic stress disorder (PTSD) and complex PTSD in eating disorder treatment-seekers: Prevalence and associations with symptom severity

Although childhood trauma and posttraumatic stress disorder (PTSD) have been well-researched in eating disorder epidemiology, prevalence rates are unavailable for complex PTSD (CPTSD). Under recently introduced ICD-11 criteria, individuals with CPTSD have both PTSD symptoms and additional disturbances in self-organization (DSO). Using ICD-11 criteria, this study aimed to determine the prevalence of PTSD and DSO symptoms, diagnostic rates of PTSD and CPTSD, and childhood trauma exposure in eating disorder treatment-seekers. Participants (N = 217) were individuals attending residential, partial hospitalization, and outpatient services who completed measures of eating disorder- and trauma-related symptoms and childhood adverse experiences. One third of participants reported PTSD symptoms, and over half reported DSO symptoms, with probable ICD-11 diagnostic rates of 3.8% for PTSD and 28.4% for CPTSD. CPTSD was significantly more prevalent than PTSD and more common in higher levels of care. Both PTSD and DSO symptom severity were positively correlated with eating disorder symptoms and impairment, rs = .285-.642. DSO symptom severity was a significant and unique explanatory factor of eating disorder severity and impairment. The findings highlight the prevalence of CPTSD in eating disorder populations and the association between DSO symptoms and eating psychopathology independent of PTSD symptoms. Implications are discussed for adjunct treatment approaches for individuals with comorbid eating disorders and PTSD or CPTSD.

Improvements of complex post-traumatic stress disorder symptoms during a multimodal psychodynamic inpatient rehabilitation treatment - results of an observational single-centre pilot study

Background: Complex post-traumatic stress disorder (CPTSD) describes chronic disturbances in self-organization (i.e. affect dysregulation; negative self-concept; severe difficulties in relationships) which are frequently observed in survivors of prolonged, repeated or multiple traumatic stressors. So far, evidence of psychodynamic treatment approaches for CPTSD is scarce.Methods: In this single-centre observational pilot study, symptom change during a 6-week psychodynamic inpatient treatment in a multimodal psychosomatic rehabilitation centre was evaluated using repeated measures analyses of variance (ANOVAs). Patients completed questionnaires on PTSD and CPTSD symptoms (ITQ), anxiety, depression and somatization (BSI-18), functional impairment (WHODAS) and epistemic trust, mistrust and credulity (ETMCQ) before (T1) and at the end of treatment (T2). A hierarchical linear regression analysis was calculated to identify factors associated with improved CPTSD symptoms.Results: A total of n = 50 patients with CPTSD were included in the study, of whom n = 40 (80%) completed treatment. Patients reported a significant reduction of CPTSD symptoms during treatment with a large effect size (-3.9 points; p < .001; η2 = .36), as well as a significant reduction of psychological distress (p < .001; η2 = .55) and functional impairment (p < .001; η2 = .59). At the end of treatment, 41.0% of patients no longer fulfilled the diagnostic criteria for CPTSD. Changes in epistemic stance included improved epistemic trust (β = -.34, p = .026) and decreased epistemic credulity (β = .37, p = .017), which together with lower age (β = .43, p = .012) and lower depression levels at baseline (β = .35, p = .054) were significantly associated with baseline adjusted mean change of CPTSD symptoms during therapy and explained 48% of its variance.Discussion: In our study, patients reported a significant reduction of CPTSD symptoms and comorbid symptoms during a multimodal psychodynamic inpatient rehabilitation treatment. Improved epistemic trust may facilitate the establishment of a trusting therapeutic relationship, thus fostering an environment of openness for knowledge transfer (i.e. social learning) and the exploration of diverse viewpoints and perspectives in the therapeutic process.

The quiet quitting scale: Development and initial validation

Introduction

COVID-19 pandemic causes drastic changes in workplaces that are likely to increase quite quitting among employees. Although quiet quitting is not a new phenomenon, there is no instrument to measure it.

Objective

To develop and validate an instrument assessing quiet quitting among employees.

Methods

We identified and generated items through an extensive literature review and interviews with employees. We carried out the content validity by content experts and we calculated the content validity ratio. We checked face validity by conducting cognitive interviews with employees and calculating the item-level face validity index. We conducted exploratory and confirmatory factor analysis to investigate the quiet quitting scale (QQS) factorial structure. We checked the concurrent validity of the QQS using four other scales, i.e., Copenhagen burnout inventory (CBI), single item burnout (SIB) measure, job satisfaction survey (JSS) and a single item to measure turnover intention. We estimated the reliability of the QQS measuring Cronbach's alpha, McDonald's omega, Cohen's kappa and intraclass correlation coefficient.

Results

After expert panel review and item analysis, nine items with acceptable corrected item-total correlations, inter-item correlations, floor and ceiling effects, skewness and kurtosis were retained. Exploratory factor analysis extracted three factors, namely detachment, lack of initiative and lack of motivation, with a total of nine items. Confirmatory factor analysis confirmed this factorial structure for QQS. We found statistically significant correlations between QQS and CBI, SIB, JSS and turnover intention confirming that the concurrent validity of the QQS was great. Cronbach's alpha and McDonald's omega of the QQS were 0.803 and 0.806 respectively.

Conclusion

QQS, a three-factor nine-item scale, has robust psychometric properties. QQS is an easy-to-administer, brief, reliable and valid tool to measure employees' quiet quitting. We recommend the use of the QQS in different societies and cultures to assess the validity of the instrument.
