Using the theory of planned behaviour to predict preventive intention on sexual behaviours among junior high school students in lower Northern region of Thailand

Abstract

This study aimed to identify the determinants of preventive intention on sexual behaviours using the theory of planned behaviour among the junior high school students in lower northern region of Thailand. Acrosssectional study with self-administered questionnaire was employed to collect survey data. Amultistage sampling technique was used to select informants. The strongest positive association with preventive intention on sexual behaviours was found for perceived self-efficacy towards preventing sexual intention. Perceived self-efficacy, perceived social belief, and perceived peer pressure/social influence had positive and significant (P< 0.001) effect on preventive intention on sexual behaviours, while perceived attitude had negative and significant (P< 0.001) effect on preventive intention on sexual behaviours. Students' behavioural intention significantly predicted preventive intention on sexual behaviours among the junior high school students in lower northern region of Thailand. The school administrators could use the theory of planned behaviour to promote sexual education programme for junior high school students.

Application of Theory Planned Behavior (TPB) and Health Belief Model (HBM) in COVID-19 Prevention: A Literature Review

“…Philippines From this study, several studies discuss the application of HBM and TPB for several public health behaviors, especially for the prevention of a disease or risk, including HIV / AIDS Prevention [4][8] [13], alcohol consumption prevention [15], injury prevention program participation [16], COVID-19 prevention [9][10] [12], preventive intention on sexual behavior [3], and tourists' health risk preventive behavior [7]. From these studies, there are several studies using extended HBM and TPB.…”

“…One of the health psychology approaches that can be used to identify the root causes of bad health behavior related to preventing the spread of disease infections is Theory Planned Behavior [3] and the Health Belief Model [4]. Theory Planned Behavior (TPB) is an extension of Theory of Reasoned Action (TRA).…”

“…TPB and HBM have been widely used for the measurement of preventive behavior in various countries and various fields, such as health, work safety, and others. Baudouin, et al [3] used TPB to predict the preventive intention on sexual behavior of junior high school students in Thailand. Siuki, et al [8] conducted research on health education interventions on HIV / AIDS prevention behavior in Iran using TPB.…”

Effect of theory of planned behavior-based educational intervention on HIV/AIDS preventive behaviors among male barbers

“…Theory of planned behavior (TPB) was developed as a theory of reasoned action in 1988 by Ajzen to predict an individual's intent to involve in a behavior at a definite place and time. The theory was recommended to describe all behaviors, over which people can exert self-control [9,10]. TPB consists of six constructs that jointly characterize a person's real control over a behavior.…”
