Survivors of Sex Trafficking: Occupation-Based Interventions for Executive Functioning

Overview

Persons traumatized through sex trafficking can demonstrate similar neurobehavioral and executive function (EF) deficits as persons with cortical injuries. In this pilot study, occupation-based activity (OBA) programming was implemented at a residence for females who had been trafficked. The study hypothesis was that OBA would facilitate development of EF skills in these clients, enabling more successful occupational performance. Method: Eight women engaged in OBA sessions over the course of eight months. Session objectives were to maximize independence in daily life skills and to foster EF component skills such as problem-solving, decision-making, cooperation, direction following and appropriate self-expression. Outcome measures used were the Executive Function Performance Test (EFPT), the Canadian Occupational Performance Measure (COPM) and the Occupational Therapy Task Observation Scale (OTTOS). Results: Gains were seen from baseline to final session in COPM score changes meeting minimally clinical difference, and OTTOS scores showing significant improvement: t(7)= -2.49, p=.04. Preliminary findings suggest that occupation-based programming may facilitate development of EF skills in sex-trafficked women.

Individuals who are sex-trafficked experience a combination of sexual violence, emotional trauma, and physical injuries that lead to high rates of depression, anxiety and post traumatic stress disorder (PTSD) Prolonged stress and adverse learning experiences can also cause use-dependent brain changes that influence executive functioning (EF) development. Other distressing situations, such as living in poverty or in dangerous environments and experiencing early sexual trauma, can result in interrupted development of executive functioning skills Although the current OT literature in the area of human and sex trafficking provide recommendations regarding areas of advocacy, education and occupation-based interventions, there is no empirical evidence to date investigating the efficacy of occupation-based interventions with survivors of sex trafficking (SST). The research question addressed in this pilot study was whether occupation-based interventions would improve the overall occupational performance of SST living in a residential program. Therefore, the purpose was to objectively determine the efficacy of occupation-based activity to improve EF skills in SST; the researchers expected that an improvement in EF skills would translate to improved occupational performance. This pilot study used a one-group, pretest-posttest design. Participants in the study were residents of a local residential program for survivors of sex trafficking (SST). Eight women, average age, 20 to 50 years who were living in the home during the eight-month project period, engaged in the occupation-based intervention groups provided and completed assessment outcome measures (Canadian Occupational Performance Measure and the Executive Function Performance Test) before and after completing the program. Group behavior was scored at each session attended with the Occupational Therapy Task Observation Scale (OTTOS). Group sessions consisted of specific tasks performed to completion that emphasized problem-solving, decision-making, frustration tolerance and cooperation. Current performance level rating and performance satisfaction scores from the COPM, as well as scores from each area of the EFPT, were collected upon initial evaluation and at the end of the eight-month intervention period. OTTOS scores were recorded during each group intervention for individual clients and graphically recorded to demonstrate individual changes over time; day one OTTOS scores were compared to the OTTOS score of the final intervention. All comparisons were completed using two-tailed, paired t-tests with a .05 alpha level for significance.
