Computer-Based Behavior Change Guide in Increasing Physical Activity in Patients With Prostate Cancer Who Have Received Androgen Deprivation Therapy

For the qualitative characteristics collected, univariate summaries (e.g., frequency counts and proportions) will be calculated. For quantitative characteristics, means, standard deviations, medians, and ranges will be computed. The analysis will be conducted as an intent-to-treat efficacy assessment comparing the two interventions. Analyses will examine changes between baseline and follow-up scores on outcome measures by group. Comparisons will be conducted using Generalized Estimating Equations (GEE) with robust (sandwich) variance estimates.

CHAMPS is a 41-item questionnaire developed by UCSF that asks about recent participation in specific physical activities and structured exercise to measure changes in physical activity level in older adults (age 65 and up). This questionnaire estimates total weekly energy expenditure (in kilocalories per week) from low to vigorous intensity physical activities for older adults. This physical activity survey has been used and validated with cancer survivors. The 41-item questionnaire asks about engagement in vigorous, moderate, and light activities per week, including frequency and duration, du

Participants will be asked to self-report their current weight in pounds.

This questionnaire concerns the reasons why a person exercises regularly, works out, or engages in other such physical activities. It is structured so that it asks one questions and provides responses that represent external regulation, introjected regulation, identified regulation, and intrinsic motivation. The basic issue concerns the degree to which one feels autonomous with respect to exercising or engaging in physical activity. The BREQ measures the continuum of behavioral regulation in exercise psychology research. The original BREQ (Mullan, Markland & Ingledew, 1997) was developed to me

The Piper Fatigue Scale measures fatigue in cancer research, and includes subdomains of behavioral, affective, sensory, and cognitive/mood attributes of fatigue. The Piper Fatigue Scale-12 is an instrument to measure the subjective dimension of fatigue, developed by BF Piper, AM Lindsey, MJ Dodd, S Ferketich, SM Paul and S Weller. The Piper Fatigue Scale is one of the commonly used multidimensional fatigue measures in the cancer research field and includes subdomains of behavioral, affective, sensory, and cognitive/mood attributes of fatigue.

EORTC QLQ-C30 is a questionnaire developed to assess the quality of life of cancer patients. The QLQ-C30 incorporates five functional scales (physical, role, cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea and vomiting), a global health status / QoL scale, and a number of single items assessing additional symptoms commonly reported by cancer patients (dyspnea, loss of appetite, insomnia, constipation and diarrhea) and perceived financial impact of the disease. Scores range from 0-100, with higher functional scale scores indicating a higher level of healthy fu

The RAPA questionnaire was designed to provide clinicians with a tool for quickly assessing the level of physical activity of their older adult patients. It was developed after a review and evaluation of existing written questionnaires. The RAPA questionnaire was developed by University of Washington Health Promotion Research Center to provide clinicians with a tool for quickly assessing the level of physical activity of their older adult patients.

Questions about participant use and their perception of the website's features and usability will provide insights into the acceptability to revise it for further development. This is a study specific questionnaire developed to measure the frequency of use of the websites and participant preferences about exercise. Higher scores indicate better use and acceptance of the exercise information and website. In addition, the questionnaire includes an open ended question for participants to provide the study team with any additional thoughts or comments about the website.
