The Effect of an Educational Intervention Based on the Health Belief Model on Preventive Behaviors of Prostate Cancer in Military Men.

BACKGROUND: Prostate cancer is the most common malignant cancer, and after lung cancer, is the second cause of death among all types of cancer in men. This study was done to assess the educational intervention based on the Health Belief Model on the promotion of preventive behaviors of prostate cancer among military men. METHODS: The present study is a semi-experimental study that was conducted on 80 men of a military collection by using randomized-stratified sampling with proportional allocation approach in BandarAbbas in 2017. The individuals were randomly divided into two groups, intervention (n = 40) and control (n = 40). The data collection tool was a questionnaire including demographic questions, knowledge questions and questions about Health Belief Model constructs and efficiency of preventive behavior that was completed in two stages and PSA Test doing. Data were analyzed by using SPSS software-version 21-, descriptive statistics (frequency, mean and standard deviation) and inferential statistics (independent T-test and paired T-test). RESULTS: After three months intervention, the mean score of Perceived Susceptibility, Severity, Benefits, Barriers, Self-Efficacy, and preventive behavior performance were seen significantly different between the two groups (p < 0.05), 52.5% of them was done PSA Test. CONCLUSIONS: Based on the health belief model, educational intervention has been effective in promoting preventive behaviors. According the effect of Health Belief Model components on preventive behaviors it is suggested that health care providers identify the benefits and barriers of preventative behaviors and through enhancing the benefits and reducing the barriers, help men to prevent prostate cancer.

The effect of theory-based educational intervention on correct principles of manual material handling among men.

BACKGROUND: Changing human behavior for the purposes of improving the way people work is an integral part of most educational interventions. This study aimed to evaluate the effect of a model based on the theory of planned behavior (TPB) on correct principles of manual material handling (MMH) among male soldiers. SUBJECTS AND METHODS: This study was a quasi-experimental, pretest-posttest research with a control group. Furthermore, 140 soldiers, from an area located in the city of Bandar Abbas, Iran, were selected through a simple random sampling and they were divided into two groups: intervention and control (70 subjects in each group). The data were collected using a three-part questionnaire including demographic information, the theory constructs, and MMH behavior. The intervention group was given the relevant education, and after 2 months, the both groups were evaluated. RESULTS: Based on regression analysis, attitude toward behavior and perceived behavioral control were predictors for correct principles of MMH. There were significant differences between the mean scores of the theory constructs before and after the education in intervention group (P < 0.001); however, no significant differences were observed in the theory constructs in the control group after the intervention. Before the education, the mean score of MMH of the intervention group was 38.30 ± 6.45; but after, the education, this changed into 44.20 ± 6.01, and significantly increased (P < 0.001). CONCLUSIONS: Educational intervention based on the TPB was effective in improving behavior for correct MMH in soldiers. Thus, the use of such educational programs according to the constructs of the planned behavior theory is recommended.
