![]() Physical activity is defined as “any bodily movement produced by skeletal muscles that result in energy expenditure” while exercise is “any form of physical activity that is planned, structured, repetitive and purposive” and used to maintain or improve physical endurance. Although the terms “exercise” and “physical activity” have distinct definitions, they are often used interchangeably in the literature. Exercise and physical activity are increasingly being recognized as a means to reduce the risk of osteoporotic fractures by increasing muscle mass and maintaining or increasing BMD. A growing body of literature focuses on factors that affect exercise adherence including the facilitators and barriers to an exercise program.Įxercise as a means to prevent bone mineral density (BMD) loss has been explored extensively in the literature over the past two decades. Exercise and physical activity is essential to preserve bone and physical function in patients with osteoporosis. Thus, fracture prevention strategies are key to reducing this burden. As of 2010, the yearly cost to the Canadian healthcare system for treating an osteoporotic fracture was over 2.3 billion Canadian dollars. Osteoporotic fractures are more common than heart attack, stroke and breast cancer combined and hip fractures caused by this disease utilize more hospital bed days than diabetes, stroke, or heart attack. In 2010, it was estimated that 30% to 50% of women and 15% to 30% of men will suffer an osteoporotic fracture in their lifetime. The burden of this disease on individuals and the healthcare system is typically a result of fragility fractures that may result in immobility and hospitalization. Osteoporosis is characterized by low bone mass and deterioration of bone tissue. Upon further validation it is expected that this measure might be used to develop more client-centered exercise programs, and potentially improve adherence. Using an iterative approach, the development and evaluation of the PEQ demonstrated high item-content validity for assessing the facilitators, barriers, and preferences to exercise in people with osteoporosis. There are 35 categorical questions and 3 open-ended items. The 6 domains are: 1) support network 2) access 3) goals 4) preferences 5) feedback and tracking and 6) barriers. The tool consists of 6 domains and 38 questions. Through qualitative methods, items were improved until saturation was achieved. Preliminary versions of this tool showed high content validity of individual items (I-CVI range: 0.50 to 1.00) and moderate to high overall content validity of the PEQ (S-CVI/UA = 0.63 S-CVI/Ave = 0.91). There are two kinds of CVI: Item-CVI (I-CVI) and Scale-level CVI (S-CVI). Content Validity Index (CVI) is the most commonly used method to calculate content validity quantitatively. A panel of 42 experts was used to validate the instrument through quantitative (content validity) and qualitative (cognitive interviewing) methods. This study comprises two phases, instrument design and judgmental evidence. The purpose of this study was to develop the Personalized Exercise Questionnaire (PEQ) to identify these facilitators, barriers, and preferences to exercise in people with osteoporosis. ![]() Understanding exercise facilitators, barriers, and preferences may provide an opportunity to personalize exercise prescription and improve adherence. ![]() Despite the widely known benefits of exercise and physical activity, adherence rates to these activities are poor.
