Abstract
Objective
People who hear voices (auditory verbal hallucinations) often have post-traumatic stress disorder (PTSD) symptoms. Cognitive behavioural therapies (CBT) have yielded inconsistent findings when treating voices and PTSD symptoms in voice hearers. Preliminary evidence suggests imagery rescripting (ImRs) is associated with large reductions in voice hearing and PTSD symptoms. This study replicated past studies using a larger sample to examine the effectiveness of ImRs in reducing such symptoms.
Method
Participants (N = 49; 65.3% female; Mage = 35.86) were clients at an Australian transdiagnostic clinic for voice hearers. A one-arm open trial design was used with three pre-treatment baselines and a mid-treatment, post-treatment and 3-month follow up assessments of PTSD symptoms (Posttraumatic Diagnostic Scale for DSM-5), voices (Hamilton Program for Schizophrenia Voices Questionnaire) and emotional symptoms (Depression Anxiety and Stress Scales-21). Five single-item measures were administered weekly to explore the trajectories of change in trauma intrusions, voice-related distress, voice frequency and positive and negative voice valance.
Results
ImRs was associated with very large reductions in PTSD symptoms and voices (both emotional and physical characteristics of voices) and emotional symptoms at post-treatment and follow-up (η2p = 0.24–0.44). There were medium-large to large reductions in weekly symptoms of intrusions, voice-related distress, voice frequency and negative voices (η2p = 0.12–0.16) and a non-significant increase in positive voices (η2p = 0.05).
Conclusions
This study provides further evidence that ImRs is an effective treatment for voices and PTSD symptoms in voice hearers with a range of diagnoses. Randomised controlled trials are needed to compare the efficacy of ImRs to CBT protocols.
期刊介绍:
Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
