Effect of Education on Knowledge, Attitude and Behavioral Intention in Family Relative with Colorectal Cancer Patients Based on Theory of Planned Behavior

Abstract

Background: Colorectal cancer is one of most common cancers in women and men and one of the major causes of death due to neoplasia. Colonoscopy is considered as the most accurate diagnostic procedure to detect colorectal cancer at the earlier stages. Objectives: The current study aimed to evaluate the effects of an education program using the Theory of Planned Behavior on promoting behavioral intention among first degree relatives of colorectal cancer patients. Materials and Methods: A quasi-experimental study conducted to evaluate the effectiveness of an educational program to promote attitudinal factors associated with early detection of colorectal cancer in 99 first degree relatives of colorectal cancer patients aged more than 20 years in Yazd city, Iran. A researcher made questionnaire forwhich validity and reliability were confirmed by expert point of view and pilot testing was employed for data collection. Questionnaires were filled in before and after educational intervention. The registered data were transferred to SPSS 19 and analyzed by paired T-test, Man-Whitney and Wilcaxon. Results: Mean scores of knowledge, attitude, perceived behavioral control and intention regarding colorectal cancer increased after education significantly (P<0.05). Conclusions: Application of the Theory of Planned Behavior has positive influence on promoting intention behavior. It is therefore recommended to apply educational programs to promote behavioral intention.

Determining Skin Cancer Protective Behaviors in the Light of the Protection Motivation Theory among Sailors in Bandar-Bushehr in the South of Iran

“…In the present research, protection motivation showed to be positively correlated with perceived severity and rewards. These findings were consistent with a body of research by Afshari et al, (2016), Baghianimoghadam et al, (2012) and Sadeghi et al, (2019). Yet, these findings were inconsistent with the results reported by Morovati Sharifabad et al, (2009).…”

“…To explain this correlation, it can be acknowledged that the more trust people put in their own capabilities of adopting protective behaviors, the better their perceived severity of the disease and the higher the chances of adaptive behaviors. These findings were consistent with those of several studies (Baghianimoghadam et al, 2012, Moradhaseli et al, 2019, Searle et al, 2000. In other words, sailors who perceived themselves self-efficacious in adopting protective behaviors, tended to show these behaviors more.…”

“…Thus, it is essential to take sailors' perceptions into account in planning and developing educational programs. Sun protective behaviors are essential to prevent skin cancer (Baghianimoghadam et al, 2012).…”

The effect of educational intervention based on theory of planned behavior on the improvement of colorectal cancer screening intention among average-risk individuals referring to Asadabad city clinics

“…indicated that education based on the theory of planned behavior (TPB) can increase the individual's behavioral intention to participate in the CRC screening programs and the use of this theory is recommended in the educational interventions which are conducted to increase the behavioral intention to participate in the CRC screening programs. [ 18 ] Regarding what mentioned above, the present study aims to “investigate the effect of educational intervention based on the TPB on the improvement of CRC screening intention among average-risk individuals referring to Asadabad city clinics,” to be a basis and guideline to implement the educational interventions among people at risk of CRC to increase their participation in the screening programs.…”

Effectiveness of an Educational Intervention Based on the Theory of Planned Behavior on Fertility Intention of Single-child Women: A Field Trial Study

“…One of the most effective theories of health education in the "fertility intentions" is the Theory of Planned Behavior (TPB) [9]. According to this theory, the most important determinant of a person's behavior is "behavioral intention"; then a combination of attitudes toward "behavior", "abstract norms", and "perceived behavioral control" can lead to a behavior:…”
