Health Behaviour and Behaviour change 3

Theory of Planned Behavior (TPB)

A model that suggests behavior results from a rational, linear process where individuals evaluate potential costs and benefits of their actions.

Health Belief Model (HBM)

Developed by Rosenstock; it states that health behavior engagement depends on health beliefs, including perceived susceptibility and severity.

Perceived Susceptibility

An individual's belief about how likely they are to contract an illness.

Cues to Action

Triggers that prompt behavior change, including both internal and external cues.

Protection Motivation Theory (PMT)

A model focusing on how individuals are motivated to protect themselves based on threat and coping appraisals.

Threat Appraisal

Evaluating the severity and personal susceptibility to a threat.

Coping Appraisal

Evaluating the response efficacy and self-efficacy regarding a behavior change.

Implementation Intentions (IMPs)

Plans that specify when, where, and how to achieve a goal, enhancing goal-directed behavior.

Intention-Behavior Gap

The difference between forming an intention and executing the behavior.

Perceived Benefits

The positive outcomes associated with engaging in a preventive behavior.

Perceived Costs

Barriers individuals face when considering a behavior change, such as time or expense.

Health Motivation

The willingness to comply with health recommendations and intentions to act.

Experimental Evidence of IMPs

Aarts et al. (1999) showed faster reactions to cues; Webb & Sheeran (2004) found increased accessibility of cues.

Goal Intentions

What one aims to achieve, such as a specific health goal.

Self-Efficacy

The belief in one's ability to perform a behavior needed for achieving intentions.

Application of IMPs

IMPs can improve the likelihood of following through on intentions by specifying the context in which one will act.

Positive Effect of IMPs

Demonstrated impact on behavior change in areas like self-examinations and increasing exercise.
