An Exploratory Study Using Cortisol to Describe the Response of Incarcerated Women IPV Survivors to MAMBRA Intervention

Abstract

Objective . To determine if incarcerated women survivors of IPV had a physiological response to the Music and Account-Making for Behavioral-Related Adaptation (MAMBRA) intervention, as measured by cortisol levels. Methods . A single-group repeated measures designed exploratory study was used to pilot-test MAMBRA. A convenience sample ( n=33 ) was recruited in a Midwestern women’s correctional facility. Serving as their own control, participants provided demographics and pre-/post-MAMBRA salivary samples while attending four MAMBRA sessions. Baseline data were compared to participants’ data collected over the remaining 3 MAMBRA sessions. Data were analyzed with descriptive and univariate statistics with an alpha of .05 and post-hoc power of .65. Results . Participants were predominantly White (52%), single (80%), and early middle-aged ( x-AGE=38.7±9.4 ), with a history of physical/nonphysical spousal abuse. Using a subsample ( n=26 ), salivary cortisol decreased between the pre-/post-MAMBRA over the sessions ( F(3,75)=4.59 , p
