Loving-Kindness Meditation for PTSD
2020年3月9日 更新者：VA Office of Research and Development
A Trial of Loving-Kindness Meditation and Cognitive Processing Therapy for PTSD
This randomized controlled trial will assess whether a novel complementary and alternative medicines (CAM) intervention, Loving-kindness Meditation (LKM), is not meaningfully inferior to another group-based PTSD treatment , Cognitive Processing Therapy (Cognitive Only version; CPT-C) for reductions in PTSD and depressive symptoms.
170 male and female Veterans with current PTSD will be randomized to LKM or CPT-C.
The investigators hypothesize that Veterans randomized to LKM will report mean reductions in PTSD and depressive symptom severity that are not meaningfully worse than CPT-C.
The investigators further hypothesize that reductions in posttraumatic maladaptive beliefs will more strongly mediate PTSD and depressive symptom improvement for those assigned to CPT-C than those assigned to LKM.
研究概览
详细说明
Aim 1: Evaluate if LKM is non-inferior to CPT-C in producing reductions in PTSD symptoms among Veterans with current PTSD. Aim 2: Evaluate the non-inferiority of LKM and CPT-C in producing reductions in depressive symptoms among Veterans with current PTSD. Exploratory Aim: Evaluate potential mediators of response to LKM and to CPT to provide preliminary information regarding whether they are consistent with the mechanisms of change conceptualized by each intervention to be associated with improvement in PTSD and depression.
Methods: A randomized controlled non-inferiority trial comparing LKM to CPT-C. In the proposed project 170 Veterans with PTSD will be randomized to LKM or CPT-C. Comprehensive assessments will be performed at baseline as well as at the end of the 12-week interventions and 3 and 6 months later. PTSD symptoms, depression, posttraumatic maladaptive cognitions and self-compassion will be assessed weekly during the treatment phase to assess temporality of change and to assess mediators of outcomes.

Clinician Administered PTSD Scale (CAPS-5) Score
大体时间：6 months post-intervention
|
PTSD diagnostic severity was measured using the 30-item CAPS-5 structured interview (range 0-80; higher scores indicate worse PTSD).
Linear mixed effects models (LMM) were used to analyze continuous outcomes, with time and time by treatment interaction included as fixed effects to determine if differences exist between conditions by time.
Non-inferiority of LKM to CPT-C was claimed if the lower limit of the 95% confidence interval for difference in change rate from baseline to 6-month follow-up in mean CAPS or depression score was greater than (i.e., did not extend beyond) negative delta (defined as 5 points on the CAPS-5 measure).
A 2-sided 95% confidence interval of the difference in change rate from baseline to 6-month follow-up between groups (CPT-C minus LKM) was calculated, with a positive value indicating a greater reduction in scores from baseline for LKM compared to CPT-C.

NIH Patient-Reported Outcomes Measurement Information System (PROMIS) Depression Score
大体时间：6 months post-intervention
|
Depression was assessed using the National Institute of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) depression measure.
This scale utilizes item-response theory and is scored using a T-score metric with a mean of 50 and SD=10 in the US general population.
Higher scores indicate more severe depression.
