DEVELOPMENT AND EVALUATION OF A MOBILE-BASED WEIGHTED WELL-BEING SCORING FUNCTION FOR TRAUMA AFFECTED COMMUNITIES.
Doctoral Dissertation, University of Pittsburgh.

Abstract
Trauma affected communities (TACs) are population groups in which members have experienced chronic traumatic events. This dissertation research defines “trauma informed” communities as services which have been tailored and evaluated specifically for the needs of communities in which trauma and violence have been seen. This dissertation details the process of designing and evaluating a first of a kind intervention via a weighted mobile app with the idea of trauma informed services in mind. This research is part of a larger project known as imHealthy, a comprehensive health status evaluation system, which represents an entire ecosystem of mobile technology coupled with various other software components. My dissertation addresses the feasibility of building a well-being scoring system from the ground up. A preliminary study was conducted to test the usability of a well-being app. The results showed that further attention was needed in addressing various user-interface (UI) sizing issues. Upon modification and a re-test, a positive time on task results was seen. The total time spent logging into the app dropped by 50%; navigation between domains dropped by 43%, navigation within pages dropped 82% and overall total time to logout dropped by 44%. In addition, a scoring algorithm was devised to weight and score the mobile-based wellbeing survey. A step-by-step approach outlines the process of the scoring function and the calibration of the algorithm. Initial results showed inconsistencies between expert raters vs. the app generated score (inter-rater reliability (ICC) values for five domains were physical = .279, behavioral = .237, relational = .029, spiritual = .497, socio-economic = -.268). Post calibration the ICC results improved significantly (physical = .797, behavioral = .749, relational = .742, spiritual = .905, socio-economic = .286). Lastly, a usability study was conducted to test user satisfaction of an administrative web portal used in conjunction with the mobile app. The low ASQ (Avg. Range 1.00 - 1.52) and CSUQ (Avg. Range 1.00 – 1.95) scores during, and post study suggest highly favorable user satisfaction on the web portal.
