Skin Cancer Prevention: Psychosocial Predictors of Sunscreen Use in University Students.

Skin cancer has the most prevention potential among all cancers. Sunscreen use is an effective method in reducing the risk prevalence of skin cancer. The aim of this study was to determine the cognitive determinants of sunscreen use among university students based on the health belief model (HBM). This cross-sectional study was conducted among 301 university students in the west of Iran. Students were randomly selected to participate voluntarily in the study. Participants filled out a self-administered questionnaire. Data were analyzed by SPSS version 16 using appropriate statistical tests including correlation and logistic regression at 95% significance level. Our results indicated 44.2% of participants reported had always sunscreen use. Among the HBM constructs, cues to action with odds ratio estimate of 1.146 (95% CI 1.061, 1.239) and perceived self-efficacy with odds ratio estimate of 1.131 (95% CI 1.036, 1.234) were the more influential predictors on always sunscreen use. Female students and high levels of mother's education were significant predictors of sunscreen use. It seems these findings are useful in planning health promotion programs aimed at increasing self-efficacy for sunscreen use.

Measuring Beliefs Related to Colorectal Cancer Screening Behavior among Iranian Middle-Aged and Elderly: a Psychometric Study

The annual fecal occult blood test is a very important method for colorectal cancer early detection through screening. Our aim was to assess psychometrics of instrument measuring beliefs related to fecal occult blood test uptake among Iranian middle-aged and elderly, based on the theory of planned behavior. This cross-sectional study was performed on 150 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. Data were analyzed with SPSS software (ver. 21.0). The mean age of the respondents was 59.1 years [SD: 6.73], in the range from 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's alpha for the measured constructs of attitude, subjective norms, perceived behavior control, and behavior intention were 0.92, 0.88, 0.70 and 0.88, respectively. Our findings indicated the final scale to be adequately reliable and valid for measurement of these constructs for prediction of fecal occult blood test uptake among Iranian middle-aged and elderly.
