NCT05057624

Brief Summary

The present study is a double-blind trial that seeks to examine the feasibility, acceptability, and efficacy of a recently developed eye-tracking-based, gaze-contingent music reward therapy (GC-MRT) in individuals with posttraumatic stress disorder (PTSD). The specific aims of this study are to: (1) examine the efficacy of GC-MRT in PTSD; and (2) elucidate its underpinnings (i.e. attention control, reward processes, and exposure via counter-conditioning). The investigators hypothesize that:

  1. 1.GC-MRT will produce greater reductions in symptoms compared to PC at post-treatment and follow-up (diverting attention away from threat).
  2. 2.GC-MRT-exp will produce greater reductions in symptoms compared to PC at post-treatment follow-up (exposure via counter-conditioning by rewarding threat stimuli).
  3. 3.Exploratory analysis will compare the reductions in symptoms of GC-MRT compared to GC-MRT-exp at post-treatment follow-up.

Outcome Measures

Primary Outcomes (9)

  • Change in PTSD symptoms over time

    Reduction in symptoms as measured by the Clinician Administered PTSD Scale (Caps-5: ranging from 0-80 ). from pre- to post-treatment. Lower scores mean better outcome

    Baseline, at 5 weeks, posttreatment at 10 weeks, follow up at 3 months from last session

  • Change in depressive symptoms over time

    Change in symptoms as measured by the Hamilton Depression Rating Scale (HDRS-17; range 0-52) from pre- to post-treatment.

    Baseline, at 5 weeks, posttreatment at 10 weeks, follow up at 3 months from last session

  • Change in anxiety symptoms over time

    Change in symptoms as measured by the Hamilton Anxiety Rating Scale (HAM-A); range 0-56) from pre- to post-treatment.

    Baseline, at 5 weeks, posttreatment at 10 weeks, follow up at 3 months from last session

  • Changes in illness severity and improvement over time

    Reduction in overall symptoms as measured by the Clinical Global Impressions scale (illness severity rated 0 to 7, with higher scores indicating more severe illness; improvement rated 0 to 7, with higher scores indicating less improvement.)

    Baseline, at 5 weeks, posttreatment at 10 weeks, follow up at 3 months from last session

  • Change in the severity of PTSD symptoms over time.

    Assesses for change in individual symptoms of PTSD and PTSD severity as measured by the Posttraumatic Stress Disorder Checklist (PCL-5). The severity of 20 PTSD symptoms is rated from 0 to 4, with higher numbers indicative of greater severity (score range of 0 to 80.)

    Baseline, at 5 weeks, posttreatment at 10 weeks, follow up at 3 months from last session

  • Changes in suicidal ideation and depressive symptoms over time.

    Assessment and monitoring of depressive symptoms and suicidal ideation, as measured through the Beck Depression Inventory-II (BDI-II). Scores range from 0 to 63, with higher scores reflecting more severe depression.

    each treatment session (weeks 2-10)

  • Change in the ability to experience pleasure over time.

    Change in anhedonia from pre- to post-treatment assessment will be assessed using the The Snaith-Hamilton Pleasure Scale (SHAPS: score range: 0-14, higher scores indicate less ability to experience pleasure).

    Baseline, at 5 weeks (midpoint), posttreatment at 10 weeks, follow up at 3 months from last session

  • Change in the ability to feel social pleasure over time

    Change in anhedonia from pre- to post-treatment assessment will be assessed using the the Revised Social Anhedonia Scale (SHAPS: score range: 0-14, higher scores indicate less ability to experience pleasure).

    Baseline, at 5 weeks (midpoint), posttreatment at 10 weeks, follow up at 3 months from last session

  • Change in people's experiences of music as a reward over time.

    Change in people's experiences of music as a reward and their relationship to music, as measured by the Barcelona Music Reward Questionnaire (BMRQ score range: 40-60, with higher scores indicate greater experiences of music as a reward)

    Baseline, at 5 weeks (midpoint), posttreatment at 10 weeks, follow up at 3 months from last session

Study Arms (3)

non-GC-MRT

PLACEBO COMPARATOR

Placebo- music will play at all times during the trials.

Other: Placebo GC-MRT

GC-MRT

ACTIVE COMPARATOR

Music will only play when participants view angry faces and will stop when they look at neutral faces.

Other: GC-MRT

Music will only play when participants look at neutral faces and will stop when they view angry faces.

Other: Exposure

Interventions

Participants will hear music continuously throughout the trials, without regard to the faces they look at.

Also known as: Control
non-GC-MRT
GC-MRTOTHER

Participants will hear music as a reward for looking at neutral faces and the music will stop when they focus on angry faces.

GC-MRT

Participants will hear music of their choice when they focus on angry faces, and when they look at neutral faces the music will stop.

Also known as: GC-MRT-Exp
