Application of the Theory of Planned Behavior for Weight Control in Women: A Randomized and Controlled Study Protocol

Background: The prevalence of obesity, which has become a remarkable public health concern in a global extent, is increasing with each passing day. Different methods are available to treat obesity, but the most effective and reliable treatment approach is the implementation of lifestyle and behavioral changes.

Aim: This study aims to examine the effect of education and counseling given to women according to the theory of planned behavior (TPB) on weight management.

Methods: This study was conducted as a single-blind randomized controlled study consisting of experimental and control groups. A total of 78 overweight and obese women were included in the study. The participants were assigned to either of the groups by the block randomization method. A training program consisting of a total of six sessions was applied to the experimental group and counseling was provided for 6 months. The primary outcomes of the study are Healthy Lifestyle Behaviors Scale II sub-dimensions and total score average. The secondary outcomes are body mass index and waist/hip ratio. The participants and the statistician analyzing the data were single blinded. The data will be analyzed with SPSS 22.0 package program.

Conclusion: This study will present an evidence-based approach to induce behavioral changes in women who are at a risk for obesity. In addition, based on the outcomes of the research, the effect of the TPB in motivating individuals to practice weight control will be evaluated.
