The effect of twice-weekly versus once-weekly sessions of either imagery rescripting or eye movement desensitization and reprocessing for adults with PTSD from childhood trauma (IREM-Freq): a study protocol for an international randomized clinical trial

Imagery rescripting and cognitive restructuring for inpatients with moderate and severe depression - a controlled pilot study

BACKGROUND

This controlled pilot study investigates the effect of the combined use of cognitive restructuring (CR) and imagery rescripting (IR) compared to treatment as usual among inpatients with moderate and severe depression. Alongside expert ratings and self-report tools, fitness wristbands were used as an assessment tool.

METHODS

In addition to the standard inpatient care (SIC) program, 33 inpatients with moderate and severe depression were randomly assigned to an intervention group (two sessions of IR and CR) or an active treatment-as-usual (TAU) control group (two sessions of problem-solving and build-up of positive activity). Depression severity was assessed by the Hamilton Depression Rating Scale-21 (HDRS-21), the Beck Depression Inventory-II (BDI-II), and as a diagnostic adjunct daily step count via the Fitbit Charge 3™. We applied for analyses of HDRS-21 and BDI-II, 2 × 2 repeated-measures analysis of variance (ANOVA), and an asymptotic Wilcoxon test for step count.

RESULTS

The main effect of time on both treatments was η2 = .402. Based on the data from the HDRS-21, patients in the intervention group achieved significantly greater improvements over time than the TAU group (η2 = .34). The BDI-II data did not demonstrate a significant interaction effect by group (η2 = .067). The daily hourly step count for participants of the intervention group was significantly higher (r = .67) than the step count for the control group.

CONCLUSIONS

The findings support the utilization of imagery-based interventions for treating depression. They also provide insights into using fitness trackers as psychopathological assessment tools for depressed patients.

TRIAL REGISTRATION

The trial is registered at the German Clinical Trials Register (Deutsches Register Klinischer Studien) under the registration number: DRKS00030809.

Are psychological interventions for adult PTSD more efficacious and acceptable when treatment is delivered in higher frequency? A meta-analysis of randomized controlled trials

BACKGROUND

Two systematic reviews indicated that higher treatment frequency of psychological interventions for adult PTSD may lead to higher efficacy and less dropout. Yet, a quantitative review is missing.

METHODS

We conducted a thorough systematic literature search and included trials meeting the following criteria: a) random allocation, 2) PTSD was primary treatment focus, 3) ≥ 70% interview-based PTSD rate 4) mean age ≥ 18 years, and 5) N ≥ 20. Treatment session frequency was analyzed dichotomously (< 1.5 vs. ≥ 1.5 sessions/week) and continuously (sessions per week & minutes per week).

RESULTS

A total of 160 RCTs with data from 10,556 patients were included. Analyses yielded similar treatment efficacy irrespective of treatment frequency definitions and whether differential efficacy was estimated directly via head-to-head trials or indirectly via comparisons to the same comparison group. Intense (≥ 1.5 sessions/week) vs. standard (< 1.5 sessions/week) delivery was, however, associated with significantly lower dropout rates (as a proxy for acceptability) for trauma-focused interventions (18.64% vs 11.54%, respectively, p = .024), but not for non-trauma-focused interventions.

CONCLUSIONS

We found no evidence for differential treatment efficacy of intense vs. standard psychotherapies for adult PTSD. Evidence for increased acceptability was found for intense vs. standard trauma-focused interventions.

A brief measure of guilt and shame: validation of the Guilt and Shame Questionnaire (GSQ-8)

Background: Guilt and shame regulate basic human processes such as social cognition and relations. Both emotions are also involved in the aetiology and maintenance of trauma-related mental disorders such as posttraumatic stress disorder (PTSD). However, a concise scale that adequately captures these constructs is currently lacking, impeding research efforts to understand them more thoroughly.Objective: To this end, we developed the eight-item Guilt and Shame Questionnaire (GSQ-8) in English, German, and Dutch.Method: We examined the reliability and validity of the GSQ-8 in a clinical sample of adults seeking treatment for childhood-trauma-related posttraumatic stress disorder (n = 209), a sample of adults who had suffered at least one traumatic life event reporting different levels of PTSD symptoms (n = 556), and a non-clinical sample of adults (n = 156).Results: Theory-driven confirmatory factor analyses confirmed two correlated latent factors guilt and shame with four items for each factor. Across all samples, two-factor models yielded better model fit than one-factor solutions. Measurement invariance across the three samples, gender, and Dutch and German language was mostly established. Guilt and shame composite scores were associated with PTSD symptoms, depressive symptoms, life satisfaction, mental health-related quality of life, and self-blame, thus supporting scale validity. Importantly, both subscales predicted PTSD symptoms, depression, life satisfaction, and mental health-related quality of life over and above cognitions of self-blame.Conclusions: The GSQ-8 is a parsimonious, reliable, and valid tool to assess guilt and shame in clinical, sub-clinical, and non-clinical populations, allowing applications across a broad range of research questions.

Blended delivery of imagery rescripting for childhood PTSD: A case study during the COVID-19 pandemic

Background

Despite the growing evidence that trauma-focused treatments can be applied as first-line approaches for individuals with childhood trauma-related PTSD (Ch-PTSD), many therapists are still reluctant to provide trauma-focused treatments as a first-choice intervention for individuals with Ch-PTSD, especially by telehealth. The current manuscript will therefore give an overview of the evidence for the effectiveness of trauma-focused therapies for individuals with Ch-PTSD, the delivery of trauma-focused treatments via telehealth, and a case example on how a specific form of trauma focused therapy: Imagery Rescripting (ImRs) can be applied by telehealth.

Method

This article presents a clinical illustration of a blended telehealth trajectory of imagery rescripting (ImRs) Ch-PTSD delivered during the COVID-19 pandemic.

Results

The presented case shows that ImRs can be safely and effectively performed by telehealth for ch-PTSD, no stabilization phase was needed and only seven sessions were needed to drastically reduce Ch-PTSD and depressive symptoms, and to increase quality of life.

Conclusion

This case report shows the effectiveness of ImRs by telehealth for Ch-PTSD, which gives hope and additional possibilities to reach out to patients with ch-PTDS. Telehealth treatment might have some of advantages for specific patients, especially, but certainly not only, during the pandemic.
