Design of the steps to health study of physical activity in survivors of endometrial cancer: Testing a social cognitive theory model☆
Research highlights
► Exercise improves cancer survivors' quality of life and physical functioning. ► Process of exercise adoption and maintenance has received little study. ► Social Cognitive Theory can be applied to understand survivors' exercise behavior. ► Self-efficacy is a key determinant of exercise behavior. ► We need to understand how cancer survivors form self-efficacy expectations.

Social cognitive theory
To study the mechanisms of physical activity adoption and maintenance in endometrial cancer survivors we are applying a model based on Bandura’s Social Cognitive Theory (Bandura, 1977, Bandura, 1986, Bandura, 1997). Previous studies have applied Social Cognitive Theory to evaluate and increase physical activity in other populations, but this theory has not been systematically applied to study the mechanisms of exercise adoption and maintenance in cancer survivors. Furthermore, most studies have
Analysis of data
We propose a sample size of 200, based on the number of participants needed to detect Pearson’s correlation coefficients of ρ = .20 or higher with 80% power, using a significance level of α = .05. For the multiple regression analyses, we are using hierarchical modeling. In these analyses, demographic and medical characteristics are first entered into the models for a given outcome measure, followed by the social cognitive measures of interest. If approximately 4–8 demographic and medical
Moving the field forward
The Steps to Health study will elucidate how cancer survivors form self-efficacy expectations about physical activity, including how cardiorespiratory fitness and somatic sensations during exercise influence self-efficacy. In addition we will identify the types of self-efficacy that are most influential at different points in the exercise adoption and maintenance processes. It also will help us understand the influence of outcome expectations and the expectancy violation effect in a cancer

Endometrial cancer survivors' sleep patterns before and after a physical activity intervention: A retrospective cohort analysis
2018, Gynecologic OncologyCitation Excerpt :As described previously, Steps to Health participants completed a baseline assessment of their sleep, physical activity, quality of life and stress. They then received individualized exercise prescriptions based on their baseline functioning [21]. The research team supported the participants' adherence to the American College of Sports Medicine guidelines, requiring 30 min of moderate exercise 5 or more days a week or at least 20 min of vigorous exercise 3 or more days a week, via telephone-based counseling sessions, printed materials, and pedometers.
Optimizing endometrial cancer follow-up and survivorship care for rural and other underserved women: Patient and provider perspectives
2017, Gynecologic OncologyCitation Excerpt :The quality of care of EC survivors could be improved by shifting from a purely disease focused approach to a wellness-centered approach that emphasized all the patient care needs including referrals to health coaches to help EC survivors change and maintain positive heath behaviors. Evidence-based remote interventions for rural dwellers may be particularly effective in improving lifestyle behaviors and co-morbidities [24,25]. Another important finding in our study concerns the use of survivorship care plans (SCPs).
Traditional and Rasch psychometric analyses of the Quality of Life in Adult Cancer Survivors (QLACS) questionnaire in shorter-term cancer survivors 15months post-diagnosis
2014, Journal of Psychosomatic ResearchCitation Excerpt :These findings indicate that, although QLACS was developed for patients over 5 years post-diagnosis, in terms of traditional psychometrics, the questionnaire performs similarly well among shorter-term survivors. This is an important and encouraging result given that researchers are already using QLACS with shorter-term survivors (e.g. [15–18]), and because it suggests that longitudinal studies could validly use QLACS across the survivorship continuum. Although two-thirds (8/12) of the domains were free of floor effects, extremely consistent with the development studies [11,19], notably more than 15% of participants obtained the minimum score for the finance, appearance, social and family-distress domains.
Response to an exercise intervention after endometrial cancer: Differences between obese and non-obese survivors
2014, Gynecologic OncologyCitation Excerpt :This paper is a secondary analysis of data from the Steps to Health study, a 6-month longitudinal study to assess predictors of exercise behavior in endometrial cancer survivors who received a home-based exercise intervention. Specific details on study methodology have been published previously [18,19]. Participants were 100 women diagnosed with Stage I, II, or IIIa endometrial cancer who were at least 6 months post-treatment with no evidence of disease.
