PSY2028 Week 6 Behaviour Change plus Infographics 202425
Overview of Behaviour Change and Infographics
Course: PSY2028 Introduction to Health Psychology
Lecturer: Dr Rachel Stocker
Today's Lecture Breakdown
Part 1: Behaviour Change
Exploring the COM-B model and the Behaviour Change Wheel (BCW), which serve as foundational frameworks for understanding and addressing behaviour modifications in health psychology.
Recap of BCW for designing effective behaviour change interventions, emphasizing the stages of development and evaluation to ensure practical applications.
Utilizing the COM-B model to diagnose behavioral influences, which enhances understanding of individual and contextual factors that affect behaviours.
Linking diagnosis to intervention design and Behaviour Change Techniques (BCTs), focusing on collaboratively addressing barriers to behaviour change.
Part 2: Infographic Assessment
Overview of assessment brief and important information regarding expectations, objectives, and grading criteria.
Defining characteristics of a good infographic, such as clarity, engagement, and accuracy, are crucial in effectively conveying health-related information.
Time allocated for questions to clarify concepts and expectations around the infographic assignment.
The Behaviour Change Wheel (BCW)
Definition
A comprehensive framework designed for the systematic design and description of behaviour change interventions, providing guidance through a step-by-step approach encompassing intervention development and evaluation methodologies.
The BCW is based on an extensive review of 19 existing behaviour change frameworks, ensuring a robust theoretical foundation.
The COM-B Model (Michie, Atkins & West, 2014)
Components
Capability:
Physical: Skills, strength, stamina necessary for achieving the behaviour change.
Psychological: Knowledge and psychological skills that facilitate change.
Opportunity:
Physical: Availability of time, resources, and accessibility that enable the desired behaviours.
Social: Norms, acceptability, and social support within specific environments that influence behaviour.
Motivation:
Reflective: Involves conscious plans, evaluations, and intentions regarding behaviours.
Automatic: Encompasses emotional reactions, desires, and impulses that motivate behaviours subconsciously.
Using the COM-B Model
Understanding behaviour change begins with identifying the target behaviour and articulating the specific changes desired.
Recognition of influences on behaviour through the lenses of capability, opportunity, and motivation helps tailor interventions effectively.
The Theoretical Domains Framework (TDF)
Integrated within the BCW, the TDF identifies crucial sources of behaviour change through techniques that address barriers.
The TDF Domains include key areas such as knowledge, skills, and social influences which can be leveraged in interventions, further driving behaviour change outcomes.
Intervention Functions may include education, training, and restrictions tailored to target specific domains.
Policy Categories utilized can involve guidelines, legislation, and communication/marketing initiatives aimed at enhancing public health.
Three-Step Process of Intervention Development
Stage 1: Understanding the Behaviour
Define the problem behaviourally; ensure a comprehensive understanding of the context surrounding the behaviour.
Select and articulate the target behaviour precisely to focus intervention efforts effectively.
Identify specific elements that need to change to facilitate behaviour modification.
Stage 2: Identify Intervention Options
Determine the intervention functions that will best address the identified barriers and motivators.
Identify relevant policy categories that can support or hinder change.
Stage 3: Identify Content and Implementation Options
Determine the behaviour change techniques that will be deployed in intervention strategies.
Decide on modes of delivery to maximize reach and effectiveness of the interventions.
Useful Questions for COM-B Diagnosis
Capability: Do they understand the desired behaviour? Are they physically and mentally capable of performing the behaviour?
Opportunity: Do they have access to sufficient resources and social support? Is the behaviour considered normal or acceptable in their environment?
Motivation: Do they perceive the behaviour as more appealing than alternatives? Is the behaviour part of their usual routine or lifestyle?
Behaviour Change Techniques (BCTs)
Definition
The smallest part of a behaviour change intervention, BCTs are observable and replicable actions that facilitate behaviour modification
There are 93 different techniques available, allowing for flexibility in designing tailored interventions to suit various contexts.
Examples of BCTs
Goal-setting: Establishing specific, measurable objectives to improve motivation and focus.
Feedback on behaviour: Providing timely and relevant information on performance, enhancing self-regulation and awareness.
Social support: Engaging networks for encouragement or assistance, leveraging social dynamics to promote positive behaviour changes.
APEASE Criteria for Interventions
Affordable: Ensures cost-effectiveness for all involved parties.
Practicable: Feasibility must be established to ensure interventions can be delivered universally.
Effective: Substantial behaviour change potential must be demonstrated.
Acceptable: Must secure approval and support from both social and professional spheres.
Safe: Should incur no unwanted effects; equitable treatment across diverse populations is essential.
Summary of Behaviour Change Using BCW
Understand the problem by identifying and evaluating specific behaviours needing change as guided by the COM-B model.
Consider the array of intervention types and policy categories that may address the behaviours effectively.
Select and implement appropriate behaviour change techniques to facilitate targeted interventions that promote health benefits.
Well-designed infographics deliver messages rapidly and efficiently, capturing attenti
