The answers assessed components of both instrumental attitude (useful/useless, healthy/unhealthy, bad/good) and affective attitude (enjoyable/unenjoyable, boring/interesting, pleasant/unpleasant, stressful/relaxing). Answers were adjectives

that are commonly employed in the physical activity domain.24 Cronbach’s alpha for affective attitude (α=0.74) and instrumental attitude (α=0.81) were good. Subjective Norm Subjective norm was operationalized by three statements: “people close to me think that I should participate in regular physical activity”, “people who are important Inhibitors,research,lifescience,medical to me think that I should participate in regular physical activity”, and “my doctor thinks that I should participate in physical activity.” These items were scored using seven-point scales from 1 (strongly disagree) to 7 (strongly agree). Cronbach’s alpha for this part was 0.71. Perceived Behavioral Control Perceived behavioral control (PBC) was measured by four questions. The first question was how much control the subjects had over participating in regular physical activity scored Inhibitors,research,lifescience,medical from 1 (very little control) to 7 (complete control). The second question was whether or not the subjects could easily participate in regular physical activity if they wanted. The answer to this question Inhibitors,research,lifescience,medical was scored from 1 (strongly disagree) to 7 (strongly agree). The next question was how confident were the subjects that they were capable of participating

Inhibitors,research,lifescience,medical in regular physical activity. The level of confidence was ranked from 1 (not at all confident) to 7 (extremely confident). The fourth question was about extent of control that the subjects had over the amount of time they had for physical activity. The extent of the control was ranked from 1 (very little control) to 7 (complete control). Cronbach’s alpha for PBC was 0.73. Self-Efficacy We adapted the physical activity self-efficacy scale.26 This 5-item instrument was designed to assess confidence in the ability to overcome the Inhibitors,research,lifescience,medical barriers for increasing physical activity in various situations. A this website 4-point likert scale from 1 (very uncertain) to 4 (very certain)

was used for scoring. Cronbach’s alpha for this part was 0.85. Statistical Analysis Data were analyzed using the Statistical Package for Social Sciences (SPSS, v. 13). Descriptive statistics were used to determine means and standard deviations of all constructs. Kolmogorov-smirnov test was used to examine the normality of distribution of quantitative Cediranib (AZD2171) data. Quantitative data were analyzed using Pearson correlation coefficients or multiple Regression. Results Data Analyses Actual subject age ranged from 60 to 85 years (71.56±6.59). Most men were married (n=62, 51.6%), had a mean of 2.33 illnesses (SD=1.95, range 0–10), moderate level of socioeconomic status (71.9%), body mass index (BMI) of 24.74±3.46) and instrumental activities of daily living (IADL) of 77.13±8.46.
