Book Description
This manual of practical guidelines is written by internationally known experts in exercise physiology and exercise epidemiology. It's the only book that covers all available methods for assessing energy expenditure and physical activity. It includes comprehensive references on the topic and highlights promising areas for future research in measurement methodology. And the extensive appendixes include a number of useful questionnaire and interview forms that represent the most widely used - and adaptable - resources available. Measuring physical activity levels is a formidable task. Measuring Physical Activity and Energy Expenditure smooths the way, bringing together the diverse literature on the subject and providing state-of-the-art, scientific methods for assessing physical activity and energy expenditure.

Book Description
The United States Social Security Administration (SSA) administers two disability programs: Social Security Disability Insurance (SSDI), for disabled individuals, and their dependent family members, who have worked and contributed to the Social Security trust funds, and Supplemental Security Income (SSSI), which is a means-tested program based on income and financial assets for adults aged 65 years or older and disabled adults and children. Both programs require that claimants have a disability and meet specific medical criteria in order to qualify for benefits. SSA establishes the presence of a medically-determined impairment in individuals with mental disorders other than intellectual disability through the use of standard diagnostic criteria, which include symptoms and signs. These impairments are established largely on reports of signs and symptoms of impairment and functional limitation. Psychological Testing in the Service of Disability Determination considers the use of psychological tests in evaluating disability claims submitted to the SSA. This report critically reviews selected psychological tests, including symptom validity tests, that could contribute to SSA disability determinations. The report discusses the possible uses of such tests and their contribution to disability determinations. Psychological Testing in the Service of Disability Determination discusses testing norms, qualifications for administration of tests, administration of tests, and reporting results. The recommendations of this report will help SSA improve the consistency and accuracy of disability determination in certain cases.

Book Description
The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) programs. To receive SSDI or SSI disability benefits, an individual must meet the statutory definition of disability, which is "the inability to engage in any substantial gainful activity [SGA] by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." SSA uses a five-step sequential process to determine whether an adult applicant meets this definition. Functional Assessment for Adults with Disabilities examines ways to collect information about an individual's physical and mental (cognitive and noncognitive) functional abilities relevant to work requirements. This report discusses the types of information that support findings of limitations in functional abilities relevant to work requirements, and provides findings and conclusions regarding the collection of information and assessment of functional abilities relevant to work requirements.

Book Description
What type, amount, and intensity of physical activity is good for your health? How much exercise is too much? Can avoiding physical activity make you ill or lead to premature death? This crisply written and thought-provoking book examines such issues to give readers the first integrated and consolidated introduction to what is known about the impact of physical activity on health. By selectively highlighting some of the best and most important research in physical activity, the authors synthesize studies and theory from several disciplines. They use a behavioral-epidemiology framework to organize the book and explore such topics as: physical activity and the health of children, adolescents, and the elderly; physical activity and its impact on mental health; the role of physical activity in prevention of particular diseases; health risks of physical activity; and how much physical activity is enough and how to measure it; how to promote physical activity and community-based physical activity interventions. Throughout the book, the authors offer studies of diverse populations, including different ethnic backgrounds and nationalities, and different gender groups, and different socioeconomic levels. Although the health benefits of physical activity are fairly well-known, this book furthers our understanding of how to help people become active enough to enjoy these benefits.

Book Description
This study investigated criterion-related validity and measurement bias of three self-report measures of physical activity among women diagnosed with breast cancer. The 7-Day Physical Activity Recall (PAR), the International Physical Activity Questionnaire (IPAQ), and the physical activity items developed by the Women's Health Initiative (WHI-Q) were compared. The study was conducted at the University of California, San Diego study site among Women's Healthy Eating and Living Study participants. Women (N = 159, average age 57 years) wore an accelerometer for one week and then completed the WHI-Q and were administered by telephone either the IPAQ or PAR. Time spent in moderate, vigorous and total physical activity was obtained from accelerometer and self-report measures. Criterion-related validity was evaluated as the Spearman rank-order correlation between accelerometer and self-report score. The proportion meeting the American College of Sports Medicine physical activity guideline (Pate et al., 1995) by self-report measure was compared to accelerometer and screening statistics computed. Measurement bias was defined as self-report minus accelerometer score; this bias could be either an over-estimate or an under-estimate of physical activity. The correlation coefficients for the PAR and WHI-Q moderate and total physical activity scores were highest (.65 to .73) compared to the IPAQ (.26 and .33). Vigorous score correlations did not differ by self-report measure (.47 to .59). The PAR had the highest sensitivity (100%) and specificity (84%) compared to the other measures. Moderate physical activity was over-estimated on the IPAQ by 239% (225 min/week) compared to 11% on the PAR. Over-reporting of vigorous physical activity on the WHI-Q was associated with increasing body mass index. Increasing under-reporting of moderate and total physical activity was associated with decreasing age on all measures but with body mass index on the WHI-Q only. Social desirability was not significantly associated with measurement bias. The study found clear differences between the self-report measures: the WHI-Q was comparable in validity to the PAR while the IPAQ had lower validity and also significant over-estimates of moderate physical activity. Using the accelerometer as the criterion against which self-report scores were compared was discussed as a limitation of this investigation.
