A Feasibility Study of Intensive Treatment With Prolonged Exposure
- Conditions
- Post Traumatic Stress Disorder
- Interventions
- Behavioral: Intensive treatment with prolonged exposure
- Registration Number
- NCT05207462
- Lead Sponsor
- Karolinska Institutet
- Brief Summary
The primary objective with this study is to investigate the feasibility and acceptability of intensive treatment with prolonged exposure (I-PE) in regular Swedish psychiatric care. The secondary objective is to investigate preliminary effects of i-PE in terms of reducing symptoms of post-traumatic stress, depression and increase quality of life.
- Detailed Description
The investigators will investigate I-PE delivered as a one-week intensive treatment consisting of nine individual sessions and five group sessions followed by three individual session two, four and eight weeks afterwards in a pilot trial. The feasibility and acceptability and preliminary effects of treatment- and assessment procedures will be evaluated using a within-group design with repeated measurements and qualitative interviews. The individual sessions will consist of imaginal exposure and processing and the group sessions of psychoeducation, rationale for treatment and in vivo exposure work. Recruitment is designed to be broadly inclusive with minimal exclusion criteria. Patients will be recruited from a psychiatric clinic specialised in PTSD in Stockholm, Sweden.

- Primary Outcome Measures
Name Time Method The proportion of participants that go through the entire treatment period Completion of treatment period, up to the last session delivered eight weeks after the massed treatment week Number of imaginal exposures made by the participant during the treatment period Through treatment, up to the last session delivered eight weeks after the massed treatment week Number of individuals offered the intervention but declined part of treatment Baseline Treatment acceptability
Number of in vivo exposures made by the participant during the treatment period Through treatment, up to up to the last session delivered eight weeks after the massed treatment week The proportion of participants that conducts the weekly measures and further assessment points Through study completion up to the 6 months follow up Participants satisfaction with treatment, assessed by The Client Satisfaction Questionnaire (CSQ-8). Completion of the massed treatment period (one week) The CSQ-8 yields a single score measuring a single dimension of overall satisfaction. An "overall score" is calculated by summing the score on each of the eight scale item. Scores range from 8 to 32, with higher values indicating higher satisfaction.
Adverse events related to the treatment Through study completion, up to the 6 months follow up Treatment acceptability
Participants experience/satisfaction with treatment and assessment procedures through qualitative interviews Completion of the massed treatment period up to post-treatment Qualitative interviews
Number of drop-outs from treatment Completion of treatment period, up to the last session delivered eight weeks after the massed treatment week Treatment acceptability
- Secondary Outcome Measures
Name Time Method Change in PTSD symptoms as assessed by the Clinician Administered PTSD Scale (CAPS-5) Pre-treatment, 6 months follow up The CAPS-5 is structured interview that assesses the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM-5) criteria for PTSD (Weathers et al., 2013). Each item is rated on a severity scale ranging from 0 (Absent) to 4 (Extreme/incapacitating) and combines information about frequency and intensity for each of the 20 symptoms. Total Score (Range 0-80 with higher scores representing more PTSD symptoms.
Change in PTSD symptoms as assessed by the PTSD Check List - DSM-5 (PCL-5) Baseline, daily through the treatment 1 week, at the 2, 4 and 8 week sessions and the 6 months follow up. The PCL-5 is a 20-item self-report measure based upon the Diagnostic and Statistical Manual (DSM-5) criteria for PTSD. Total Score (Range 0-80 with higher scores representing more PTSD symptoms.
Change in ICD-11 PTSD and complex PTSD symptoms as assessed by the International Trauma Questionnaire (ITQ). Baseline, daily through the treatment 1 week, at the 2, 4 and 8 week sessions and the 6 months follow up. The ITQ includes six items measuring each PTSD symptom cluster and these items measure how bothersome each symptom has been in the past month. The ITQ also includes six items measuring each 'Disturbance in Self-Organization' (DSO) symptom in complex PTSD. These items measure how a respondent typically feels, thinks about oneself, and relates to others. The PTSD and DSO symptoms are accompanied by three items measuring associated functional impairments in the domains of social, occupation, and other important areas of life. All items are answered on a 5-point Likert scale ranging from 0 (Not at all) to 4 (Extremely). Thus, PTSD and DSO symptom scores range from 0 to 24 and CPTSD symptom scores range from 0 to 48. Higher scores represents more PTSD and complex PTSD symptoms.
Change in depressive symptoms as measured by the Patient Health Questionnaire-9 (PHQ-9) Baseline, last 1 day of the treatment 1 week, at the 2, 4 and 8 week sessions and the 6 months follow up. The PHQ-9 is a widely used and well-validated instrument for measuring the severity of depressive symptoms. Scores are calculated based on how frequently a person experiences 9 symptoms of depression ranging from "not at all" response is scored as 0; "several days" response is 1; "more than half the days" response is 2; and "nearly every day" response is 3. Higher scores represents more depressive symptoms.
Change in quality of life measured by Euroqol, EQ-5D Baseline, last 1 day of the treatment 1 week, at the 2, 4 and 8 week sessions and the 6 months follow up. Change in overall health from baseline to post treatment and follow up . EQ-5D is a standardized self-report measure of overall health status measured in terms of five dimensions; mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Mobility dimension asks about the person's walking ability. Self-care dimension asks about the ability to wash or dress by oneself, and usual activities dimension measures performance in "work, study, housework, family or leisure activities". In pain/discomfort dimension, it asks how much pain or discomfort they have, and in anxiety/depression dimension, it asks how anxious or depressed they are. The respondents self-rate their level of severity for each dimension using a three-level scale: 1 having no problems, 2 having some problems and 3 having extreme problems. A higher score indicate worse severity.
