Background: The workplace provides a setting to offer health promotion interventions to a large proportion of adults. Given the high rates of obesity and chronic disease among this population, it is of public health importance to provide and evaluate these interventions.
Objectives: The purpose of this study was to pilot an evaluation of the Motiv8 Workplace Series (MWS) using the RE-AIM framework. The objectives of this study were 1) to provide measures of adoption, reach, and implementation of the MWS, 2) to provide estimates of the effectiveness of the MWS in changing physical activity and healthy eating behaviours, and in changing theoretical variables from the social cognitive theory and the health action process approach, and 3) to use the data to investigate the role of theoretical variables as mediators in changing these health behaviours.
Methods: This pilot study used a quasi-experimental, non-equivalent control group design. The study population consisted of employees aged 18 and older, living in Kingston and surrounding area. The study investigated 1) the participation rate and representativeness of participating workplaces (adoption), 2) the participation rate and representativeness of employees participating in the MWS (reach), 3) the extent to which the MWS was implemented as intended (implementation), and 4) the impact of the MWS on participants through measures of behavioural outcomes (effectiveness). A questionnaire was administered at baseline and 1-week follow-up.
Results: Objective 1. The participation rate was low among workplaces. Participating and non-participating workplaces were similar with respect to all characteristics except past public health programming. There was also a low rate of participation among employees. Participants did not appear to be representative of all workplace employees. Objective 2. There was a significant difference in healthy eating (p<.05), but no significant difference in physical activity (p>.05) between participants in the intervention and comparison groups at follow-up. Objective 3. There was evidence for action planning as a partial mediator of the relationship between the intervention and healthy eating.
Conclusions: The preliminary findings from this evaluation suggest that the MWS had moderately low reach and adoption, good program implementation, and was effective at changing eating behaviour among employed adults. / Thesis (Master, Kinesiology & Health Studies) -- Queen's University, 2009-12-04 10:34:13.947
