Posttraumatic Growth, Self-Efficacy and Quality of Life in Taiwanese Overweight/Obese Endometrial Cancer Survivors Following a Home-Based Walking Program

In Taiwan, endometrial cancer (EC) is the most common gynecological cancer, and most women with EC have a good cancer prognosis for long-term survival. However, most survivors with EC are overweight or obese, and those who are obese are at significant risk for obesity-driven comorbidities that threaten their long-term quality of life (QoL). However, physical activity and weight loss are achievable in overweight/obese survivors with EC. Therefore, 150 survivors with EC will be recruited in the first year of the study to explore (1) the differences of physical activity and QoL between overweight/obese EC survivors and normal weight EC survivors; (2) the effects of demographic-disease characteristics, outcome expectations, barrier self-efficacy, self-efficacy for walking, and posttraumatic growth on physical activity; and (3) the effects of demographic-disease characteristics, outcome expectations, barrier self-efficacy, self-efficacy for walking, posttraumatic growth, and physical activity on QoL. In the second year of the study, the home-based walking program will be tested, and 120 overweight/obese survivors with EC will be recruited (60 for the immediate intervention group and 60 for the delayed intervention group) to explore (1) the differences of outcome expectations, barrier self-efficacy, self-efficacy for walking, posttraumatic growth, physical activity, and QoL between survivors in the immediate intervention group and those in the delayed intervention group; (2) the effect of the home-based walking program on body weight, posttraumatic growth, self-efficacy for walking, physical activity, and QoL; (3) the relationships between changes of posttraumatic growth, self-efficacy for walking, barrier self-efficacy, and outcome expectations and changes of physical activity; and (4) the changes of BMI, posttraumatic growth, self-efficacy for walking, and physical activity on QoL. The instruments used include the Posttraumatic Growth Inventory (PTGI), Self-Efficacy for Walking scale-Duration (SEW-Duration), Barriers Self-Efficacy scale (BARSE), Multidimensional Outcome Expectations for Exercise Scale (MOEES), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire 30 (EORTC QLQ-C30) version 3 with the EORTC QLQ-endometrial cancer module 24 (EORTC QLQ-EN24), and International Physical Activity Questionnaire-Short Format (IPAQ-SF), as well as an Actigraph accelerometer. Statistics analyses will include multivariate analysis of covariance (MANCOVA), hierarchical multiple linear regression (HMLR), hierarchical linear modeling (HLM), repeated measures analysis of variance (repeated measures ANOVA), generalized estimating equations (GEE), and two-group multivariate analysis of variance (two-group MANOVA). The results of the study can provide information for clinical health providers to conduct evidence-based interventions for overweight/obese survivors with EC, which could improve their physical activity levels and QoL.
