Investigation Of Web-Based Motivational Interviewing To Increase Physical Activity Participation Among Adults, Sasha Karnes May 2013

Investigation Of Web-Based Motivational Interviewing To Increase Physical Activity Participation Among Adults, Sasha Karnes

Theses and Dissertations

Interventions to enhance physical activity (PA) participation are needed given the high prevalence of under-activity and inactivity (CDC, 2001) and related occurrence of negative health consequences among the general adult population (Kung, Hoyert, Xu, & Murphy, 2008). Preliminary support for a therapeutic technique called Motivational Interviewing (MI) suggests promise for application to enhance PA participation (Burke, Arkowitz, & Menchola, 2003). Given the need for interventions to enhance PA and the preliminary support for MI as an intervention to increase PA, the aims of the current study were to: (a) determine if web-based MI is effective in enhancing PA participation, and (b) assess the mechanisms by which web-based MI enhances PA through changes in targeted cognitive variables. Participants (n= 23, under-active or inactive adults) engaged in four web-based MI sessions. Steps per day, PA, and cognitive variables were assessed across time. Efficacy of MI in enhancing PA participation was demonstrated through: (a) increases in steps per day (t[22]= 2.085, p = 0.049); (b) increases in total PA energy expenditure per week( χ2= 8.430, p = 0.015); and (c) increases in moderate intensity PA energy expenditure per week ( χ2= 13.853, p = 0.001). Although mediation of change in PA by cognitive variables was inconclusive due to sample size, changes were observed in the expected direction for cognitive variables including: (a) percentage of participants classified as action or ...


Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro Jan 2013

Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro

Graduate Theses and Dissertations

The development of more accurate and precise methods of assessing physical activity behavior is an important public health research priority. Objective monitoring devices have advantages but the high cost and burden of data processing make them impractical for large scale applications. Subjective (survey-based) tools are inexpensive and easy to use but these suffer from questionable validity. Objective measures are often used to validate less accurate measures such as subjective instruments but this does not directly improve the accuracy or precision of the self-report instrument. The proposed line of research developed and tested a calibration equation approach that enabled data from ...


Integrated Classroom Physical Activity: Examining Perceived Need Satisfaction And Academic Performance In Children, Miriam Ann Blom Skrade Jan 2013

Integrated Classroom Physical Activity: Examining Perceived Need Satisfaction And Academic Performance In Children, Miriam Ann Blom Skrade

Graduate Theses and Dissertations

Physical activity is related to better academic performance and prevention of childhood obesity. Classroom-based physical activities, based on recent research studies, seem to target both areas successfully. Move for Thought (M4T) is a recently developed kit that integrates physical activities into academic lessons in the classroom. This thesis is the first to examine the kit's impact on children's motivation and math performance. The study aimed to see (a) if eight weeks of M4T integrated with math, compared to traditional lessons (control), would elicit a gain in math performance and (b) if the basic psychological needs in math (autonomy ...
