Busy families of Nova Scotia and similar populations find it challenging to make healthy nutrition and exercise choices due to time constraints (Chircop et al, under review; Jabs et al, 2007; Devine et al, 2006). Smartphone application technology can provide health behavior change interventions in a mobile and fast format (Breton, Bernard, Fuemmeler, Lorien & Abroms, 2011). Using focus groups, this research addressed parent’s perceptions on how smartphone application technology can support nutrition and physical activity habits within their family and what, if any, barriers exist in adopting this form of health behavior intervention. Findings revealed this population believes smartphone health applications can improve family nutrition and physical activity as long as barriers are minimized and requirements for adoption are met. Diffusion of Innovations theory was used to understand the adoption rate within the target population. Thoughts on future work efforts for related health behaviour interventions is discussed.

Virginia Cooperative Extension's Family Nutrition Program (FNP), which includes EFNEP and SNAP-Ed, works to help limited-resource families across the state make informed food-choices. Virginia Cooperative Extension (VCE) lacks open-access physical activity resources representing individuals with varying weights, races, and ethnicities. In 2015, an integrated research-practice partnership was initiated for the development of an evidence-based physical activity resource for peer educators employed by FNP to use. The video suite, Move More, Virginia!, was created as open-access and includes demographically diverse individuals, representative of FNP clients. Study I determined client perceptions of physical activity and preferences for new resources. Study II identified FNP peer educators' perceptions of physical activity, their resource needs, and intent to use Move More, Virginia! resources. Both studies involved quantitative and qualitative data through surveys and focus groups. Formative data collected in Study I revealed the prominent themes related to clients (n=12) were physical activity facilitators (n= 100 meaning units (MU)) and physical activity barriers (n=77 MU). In Study II, peer educator responses(n=15) led to the emergence of four themes related to physical activity itself: barriers to incorporating physical activity within FNP (n=189 MU), physical activity facilitators (n=106), current delivery of physical activity (n=102 MU), and physical activity barriers (n= 16 MU). When prompted to share video specific feedback, the top theme was positive video feedback (n = 115 MU). Identified themes and subthemes provide deeper understanding of the organizational culture within FNP as thoughts, perceptions, and barriers to incorporating physical activity into FNP curriculum are highlighted. / Master of Science

Master of Public Health / Department of Human Nutrition / Mary L. Higgins / Nutrition education programs strive to help low-income people make optimal food choices while living on a limited budget. This study addressed perceived understanding, acceptance, and usability of Food and Nutrition Bytes, a set of 12 eight- to eleven-minute online Expanded Food and Nutrition Education Program (EFNEP) lessons. Clients in EFNEP during 2005-2006 were surveyed on internet usage and interest in online nutrition lessons. Lessons were developed and assessed for reading levels using two formulas. Clients and professionals in six Kansas counties completed a Likert scale survey and gave comments after they viewed one online lesson. Fifty-five percent of 75 EFNEP clients who had internet access indicated they were interested in taking nutrition lessons online. The new lessons averaged a 6.64 grade reading level. Two lessons had content that was rated too general to be useful. For the remaining lessons, both groups ranked their perceived understanding, helpfulness of graphics and audio, and usefulness of information at the first or second most-desirable rating. They rated length and amount of information as “Just Right.” The only difference found between the groups was when clients rated one lesson as having a little too much information and professionals rated it as having not quite enough (Mann-Whitney U = 35.0, p = 0.039). Within-sample associations were measured for two lessons. Clients older than 30 years of age found the Grains lesson’s pictures and graphics to be more helpful than did younger clients (Kendall tau-b = 0.593, p = 0.002). White clients evaluated the Cooking lesson as being easier to understand than did non-white clients (Kendall tau-b = -0.477, p = 0.020). The most frequent comments pertained to the importance of portion sizes and appropriate pictures and graphics. Overall, Food and Nutrition Bytes lessons were easy to read, and perceived by both clients and professionals to be easy to understand, helpful and useful, and also optimal in length and amount of information. Despite low numbers of EFNEP clients who had internet access, over half were interested in taking lessons online. Limitations of this study include small samples, convenience samples, subjects’ time constraints, and interviewer bias.
