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.

Book Description
NEW! Extensively updated content reflects the most current quantitative and qualitative approaches to nursing research, as well as the most current research tools and techniques used in the digital era. NEW! Updated research examples throughout incorporate the best examples of current literature, with increased emphasis on international examples to reflect the increasingly global nature of nursing research. NEW! Increased use of visuals includes the addition of more illustrations, tables, and boxes to help break up long passages of text for today’s more visually oriented learners of all levels. NEW! Revised chapters offer improved clarity and usability in the areas of research problems and purpose, quantitative research design, quantitative methodology, and qualitative methodology. NEW! Increased emphasis on hospital magnet status reflects the effect this status has on improving nursing competency and quality outcomes. UPDATED! Coverage of certain qualitative research content has been de-emphasized to reflect the decreased use of certain methodologies (e.g., historical research) and to allow the introduction of additional methodologies that are growing in use.

Book Description
Physical activity is vital for good health. It has an established strong evidence base for its positive effects on functional capacity, reducing the risk of many chronic diseases, and promoting physical, mental and social well-being. Furthermore, these benefits are evident across a diversity of ages, groups and populations. The need for these benefits in current societies means that exercise practitioners, professional bodies, institutions, health authorities and governments require high quality evidence to establish appropriate exercise guidelines, implementation strategies and effective exercise prescription at individual, group and population levels. Research Methods in Physical Activity and Health is the first book to comprehensively present the issues associated with physical activity and health research and outline methods available along with considerations of the issues associated with these methods and working with particular groups. The book outlines the historical and scientific context of physical activity and health research before working through the full research process, from generating literature reviews and devising a research proposal, through selecting a research methodology and quantifying physical activity and outcome measures, to disseminating findings. Including a full section on conducting research studies with special populations, the book includes chapters on: Observational and cross-sectional studies; Interviews, questionnaires and focus groups; Qualitative and quantitative research methods; Epidemiological research methods; Physical activity interventions and sedentary behaviour; and Working with children, older people, indigenous groups, LGBTI groups, and those with physical and mental health issues. Research Methods in Physical Activity and Health is the only book to approach the full range of physical activity research methods from a health perspective. It is essential reading for any undergraduate student conducting a research project or taking applied research modules in physical activity and health, graduate students of epidemiology, public health, exercise psychology or exercise physiology with a physical activity and health focus, or practicing researchers in the area.

Book Description
"This book provides information regarding epidemiologic methods used in studies of physical activity. It is intended for use by students and researchers in physical activity and in public health, and by researchers and professionals using physical activity data (e.g., exercise physiologists and health economists). Additionally, those interested in physical activity and health, who want to understand and appropriately interpret the results of physical activity studies (e.g., physicians and journalists), may also find the book useful."--BOOK JACKET.
