Mental Health Symptoms
Lee and colleagues (2017) found that participants in the meditation treatment group reported fewer mental health symptoms, compared with participants in the control group, who received services as usual. This difference was statistically significant.
Participants in the treatment group demonstrated fewer trauma symptoms, compared with participants in the control group. This difference was statistically significant.
Reliable Change in Mental Health Symptoms
Compared with participants in the control group, a greater number of participants in the treatment group achieved a reliable change in mental health symptoms (i.e., a difference of at least 11 points on the Symptom Distress Scale to indicate a reliable change that is not a result of chance). This difference was statistically significant.
Reliable Change in Trauma Symptoms
Compared with participants in the control group, a greater number of participants in the treatment group achieved a reliable change in trauma symptoms (i.e., a difference of at least 11 points on the Modified PTSD Symptom Scale to indicate a reliable change that is not a result of chance). This difference was statistically significant.
Lee and colleagues (2017) conducted a randomized controlled trial to determine the effects that meditation had on mental health and trauma symptoms of female survivors of interpersonal violence (IPV) with co-occurring disorders (CODs). This study took place in a midwestern metropolitan area. Participants were recruited from a substance abuse treatment and housing program for homeless women, and clients were considered eligible for the study if they had experienced interpersonal abuse and had CODs. Clients with schizophrenia, severe depression, or who were actively suicidal were excluded from the study.
Of the 63 total clients recruited, 32 were randomly assigned to the treatment group, and 31 were assigned to the control group. Of these participants, 31 women in the treatment group and 25 women in the control group completed the study. Participants in both groups received regular services provided by the agency, including group therapy, individual counseling, and substance abuse treatment, but the treatment group received the additional meditation classes, whereas the control group did not. The age of participants ranged from 22 to 56 years, with an average age of 38.6. Of the participants, 58.6 percent were white, and 41.4 percent were nonwhite. Of this group, 53.4 percent were single, 24.1 percent were divorced, 15.5 percent were separated, 6.9 percent were widowed, and 0 percent were married. Regarding education, 10.3 percent of the participants had graduated from college, 53.5 percent had some college education, 20.7 percent had graduated high school, and 15.5 percent did not finish high school. All participants had DSM-IV diagnoses in substance-related disorders: 39.7 percent for cocaine dependence, 32.8 percent for alcohol dependence, 15.5 percent for opioid dependence, 6.9 percent for polysubstance dependence, 3.4 for cannabis dependence, and 1.7 percent for amphetamine dependence. In addition to substance-related disorders, 32.8 percent of participants had been diagnosed with depression disorders, 27.6 percent with bipolar disorders, 12.1 percent with anxiety disorders, and 12.1 percent with posttraumatic stress disorder (PTSD). All participants also had experienced trauma: 82.5 percent through physical abuse, 82.5 percent through emotional abuse, and 78.9 percent through sexual abuse. The two groups only varied in race/ethnicity: 71.9 percent of the treatment group was white, compared with 42.3 percent of the control group. No adjustments were made.
Outcomes of interest included mental health and trauma symptoms, and a reliable change in mental health and trauma symptoms between the pre- and posttest. Mental health symptoms were measured by the Symptom Distress Scale (SDS) of the Ohio Department of Mental Health Adult Consumer Form. The SDS is a self-report instrument consisting of 15 items, which asks participants to rate their own mental health symptoms on a 5-point Likert scale. The score of the SDS can range from 15 to 75, with a higher score indicating a greater level of symptom distress. The Reliable Change score is calculated at 11; therefore, a difference of at least 11 points from pre- to posttest indicates a reliable change that is not the result of chance. Trauma symptoms were measured by the Modified PTSD Symptom Scale (MPSS), a 17-item instrument to measure the frequency and severity of PTSD symptoms within the past 2 weeks. The MPSS has three subscales: 1) Re-experiencing, 2) Avoidance/Numbing, and 3) Arousal. The score of the MPSS can range from 0 to 119, with higher scores indicating more severe PTSD symptoms. The Reliable Change score is calculated at 10; therefore, a difference of at least 10 points from pre- to posttest indicates a reliable change that is not the result of chance. Paired-sample t tests were used to examine changes in scores from pretest to posttest, and an analysis of covariance (ANCOVA) was used to compare treatment and control groups. The study authors did not conduct subgroup analyses.
