Summary
The theory of planned behaviour (TPB) effectively predicts risky driving, with attitude being a key factor in intention. Understanding these predictors is vital for creating effective road safety interventions.
Area of Science:
- Psychology
- Traffic Safety
- Behavioral Science
Background:
- High-risk driving behaviors pose significant public health challenges.
- The Theory of Planned Behaviour (TPB) is a prominent framework for understanding volitional behaviors.
- Limited meta-analyses exist on TPB's efficacy in predicting diverse risky driving actions.
Purpose of the Study:
- To systematically evaluate the Theory of Planned Behaviour's predictive power for various high-risk driving behaviors.
- To identify the relative importance of TPB constructs (attitude, subjective norm, perceived behavioural control, intention) across different driving behaviors.
- To inform the development of targeted road safety interventions based on behavioral science.
Main Methods:
- A comprehensive meta-analysis of studies quantitatively measuring TPB variables and risky driving behaviors.
- Searched four major electronic databases (PubMed, Web of Science, Scopus, ProQuest).
- Included 80 records comprising 94 independent samples, assessed for bias using the JBI checklist.
Main Results:
- TPB constructs (attitude, subjective norm, perceived behavioural control) explained 30%-51% of the variance in intention.
- Attitude emerged as the strongest predictor of intention across all examined driving behaviors.
- The TPB model accounted for 36%-48% of the variance in predicting observed behaviors for speeding, distracted driving, and speed compliance.
Conclusions:
- The Theory of Planned Behaviour is a valuable framework for understanding and predicting high-risk driving.
- Targeted road safety interventions should consider the varying influence of TPB constructs on different driving behaviors.
- Further research can refine TPB applications for enhanced traffic safety outcomes.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:52Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

01:30Social Cognitive Perspective on Personality
507
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:08Determination of Expected Frequency
2.1K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...
