“…Participants also provided concrete and useful advisement that informed a subsequent VDOT pilot study. 19 Patient and provider insights into VDOT feasibility and acceptability indicated that VDOT could play an important role in supplementing the array of TB care continuity approaches currently used in San Diego and 23 For example, in a study conducted by Zú ñ iga and colleagues on barriers to HIV clinical trials participation in San Diego, patients and providers agreed that lack of transportation to the clinic was a barrier. 23 Qualitative study findings revealed, however, that Latino participants were apprehensive about taking public transportation due to immigration concerns, while providers perceived it as a lack of transportation.…”

“…Details on processing Actigraph GT3X' accelerometer data using ActiLife 6 Data Analysis Software including how to conduct wear time validation is available elsewhere. 18 In brief, the Troiano technique 19 was used to set parameters to detect non-wear periods for wear time validation, specifically: a ''minimum length'' of 90 minutes of consecutive zeros to define a ''non-wear'' period; a ''spike tolerance'' (or ''spurious count'' tolerance) of 2 minutes to continue counting non-wear periods as non-wear until this threshold was met; ''wear periods'' of less than 10 minutes were ignored; ''minimum wear time per day'' was set to 600 minutes per day; and ''minimum days of valid wear time'' was at least 5 days per week including a weekend day. 18 Statistical Analysis Descriptive statistics were conducted for all variables.…”

“…Studies have shown that it is possible to effectively train or coach participants, including those who were overweight, to self-monitor their PA by keeping records/logs in a diary, webpage, or PDA. 12,19,28,29 Future studies could examine how SMS-based prompts can be used to prompt self-monitoring, and thus increase their level of engagement with the device, to promote PA.…”

“…These include a feasibility study in Kenya, 18 and work completed by members of our own team to pilot test VDOT involving videos recorded by TB patients using smartphones, which are subsequently observed by a healthcare provider through a secure website. 19 Interventions that make use of video capabilities available on most cell phones, however, have been largely unexplored for TB medication adherence and pose a promising application for TB patients in both low-and high-resource settings. 20 The current binational qualitative study was undertaken to assess the acceptability and feasibility of cell phone-based VDOT for monitoring TB treatment adherence in the U.S.-Mexico border region prior to developing and pilot-testing the application.…”

“…This paper presents the results of a qualitative study conducted to inform the design and implementation of a subsequent binational pilot study of a VDOT application for TB treatment monitoring. 19 …”
