A genetic influence on odor identification was suggested for males, but not for females, consistent with previous twin research on physical measures. In addition, females scored(More)
INTRODUCTION The Rapid Assessment of Physical Activity (RAPA) was developed to provide an easily administered and interpreted means of assessing levels of physical activity among adults older than 50 years. METHODS A systematic review of the literature, a survey of geriatricians, focus groups, and cognitive debriefings with older adults were conducted,(More)

Genetic and environmental influences in the determination of individual differences in self-reported symptoms of separation anxiety (SAD), overanxious disorder (OAD), and manifest anxiety (MANX) were evaluated in children and adolescents for three age groups (8-10, 11-13, and 14-16). Symptom counts for SAD and OAD were assessed for 1,412 twin pairs using(More)
Parental reports and children's self-reports of manifest anxiety were obtained from a community-based sample of twin pairs on two occasions approximately 19 months apart, using the Revised Child Manifest Anxiety Scale (Reynolds & Richmond, 1978). In prior cross-sectional studies, a low degree of agreement between parent and child assessments of anxiety was(More)

OBJECTIVE To compare the self-perceived quality of life (QoL) of adolescents with and without disabilities. METHOD A school-based survey was conducted with 2801 7th to 12th grade students in a rural area of the United States.

OBJECTIVES Telephone survey data are widely used to describe population health, but some fear that people with disabilities cannot participate. We tested the hypothesis that a telephone survey would underrepresent adults with disabilities, and that the adults with disabilities who responded would report lower prevalences of sensory, mental, self-care, and(More)
INTRODUCTION We report on development and preliminary validation of a brief, telephone-based measurement tool for assessing physical activity in older adults. The Telephone Assessment of Physical Activity (TAPA) questionnaire is based on the University of Washington Health Promotion Research Center's Rapid Assessment of Physical Activity (RAPA), a written(More)
