The study was developed according to procedures defined by Ajzen and Fishbein.24 Data Collection Participants were individually interviewed for 45 minutes using questions in regards to their demography, physical activity beliefs, and physical activity behavior, respectively. The interviewer explained questionnaires used for data collection to the participants to prevent illiteracy or vision difficulties from affecting the study participation or findings. Instruments In order to assure the validity of the Persian version of the questionnaire, it was translated into Persian Inhibitors,research,lifescience,medical and then back into English. The translation and back translation were performed by two different linguistic students.

The translations were then compared and the questionnaire was corrected accordingly. Inhibitors,research,lifescience,medical The questionnaire was then given to 10 professionals in Health Education, sociology and Gerontology at to examine the item clarity, face validity, and content validity. The questionnaire was then modified based on their suggestions and comments. Reliability of the questionnaire was evaluated using a sample

of 20 subjects over 10 days using Inhibitors,research,lifescience,medical test-retest for physical activity behavior, and Cronbach’s alpha for other items. Participants were instructed to answer all questions based on the definition of regular physical activity. Regular physical activity was defined as a moderately intense physical activity (such as brisk walking) that is Inhibitors,research,lifescience,medical performed ideally every day for a minimum of 30 minutes. The duration of regular physical activity may be fulfilled either in a single session or accumulated in multiple bouts of at least 8–10 minutes throughout the day. Questions of TPB were based on previously used measures of TPB constructs, and were all measured on 7-point scales.13 Physical Activity Intention Inhibitors,research,lifescience,medical Physical activity intention was measured with a single item modeled after Ajzen’s work in 1999. Subjects were asked about the extent of their agreement with the statement that they intend to perform regular physical activity.

Physical Activity Behavior Physical activity was measured using the Physical Activity Scale Florfenicol for the Elderly (PASE).25 The PASE is a brief instrument designed specifically to assess the frequency and duration of recreational, leisure, and occupational physical activity in older adults over a 7-day period. Frequency was http://www.selleckchem.com/products/cobimetinib-gdc-0973-rg7420.html categorized by as never, seldom (1-2 days/week), sometimes (3-4 days/week), and often (5-7 days/week). Duration was categorized as less than 1 hour, between 1-2 hours, 2-4 hours, and more than 4 hours. The total PASE score was computed by multiplying the duration of time spent in each activity or participation (yes/no) by the empirically-derived item weights, and summing up all activities. A higher PASE score represents a greater physical activity behavior. Reliability, evaluated in 20 subjects over 10 days, was (correlation coefficient=0.76).
