The present study will investigate the efficacy of "Trauma-Informed Mind-Body Wellbeing Program" ("TI-MBW"), a 10-12 session yoga-based program for community members in Kenya which has a 5-day training period for yoga teachers. The yoga teachers were trained by the Africa Yoga Project (AYP), an organization which aims to increase wellbeing through offering yoga to communities in Africa. Trauma has direct effects on an individual's physical and mental wellbeing and has shown improvements through somatic practices such a yoga and mindfulness. Trauma in Kenya is highly prevalent due to three main concerns: poverty related stress, gender-based violence, and post-election violence. This study emphasized decreasing traumatic distress and increasing wellbeing through a cognitive-relational framework. It was hypothesized that engaging in the TI-MBW program would be acceptable, feasible, not cause an increase in trauma-related symptomatology, and not result in inferior results than the usual yoga program delivered by AYP. Second, it was hypothesized that teachers participating in TI-MBW would show decrease in symptoms of traumatic, psychological distress related to nerves, mood, and thoughts and behaviors, and increase in self-efficacy, self-regulation, and personal growth beliefs significantly more than controls. Originally, it was hypothesized that the students of the TI-MBW teachers would also reflect these changes. However, due to data collection issues, analyses on student data were not possible. Results from teacher data indicate that consistent with prior research in yoga interventions, traumatic distress was reduced and wellbeing was increased, with the TI-MBW teachers showing statistical significance in increased self-regulation compared to controls. Within TI-MBW teachers, significant increases were seen in self- regulation, personal growth beliefs, and significant decreases were seen in all traumatic psychological distress subscales. Within controls, significant decreases were seen in overall traumatic distress and thoughts and behaviors. Interestingly, self-efficacy scores decreased in both groups over time. Importantly, the program proved to maintain participant safety and a non- inferiority to the yoga program as usual. Possible reasons for these findings as well as directions for future research are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
