This cross-sectional study was performed on150 middle-aged and elderly who were randomly selected to participate voluntarily in Kermanshah, in the west of Iran.The studied constructs included attitude, subjective norms, perceived behavior control, and behavior intention. Datawere analyzed with SPSS software (ver. 21.0). The mean age of the respondents was 59.1 years [SD: 6.73], in the rangefrom 50 to 73. All of the loads of the exploratory factorial analysis were larger than 0.4. KMO was calculated as 0.756.Overall, four factors under investigation accounted for 82% of the variance in the hypothesized model. Cronbach’salpha for the measured constructs of attitude, subjective norms, perceived behavior control, and behavior intentionwere 0.92, 0.88, 0.70 and 0.88, respectively. Our findings indicated the final scale to be adequately reliable and valid formeasurement of these constructs for prediction of fecal occult blood test uptake among Iranian middle-aged and elderly.
