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
  1. Capability:

    • Physical: Skills, strength, stamina necessary for achieving the behaviour change.

    • Psychological: Knowledge and psychological skills that facilitate change.

  2. 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.

  3. 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

  1. 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.

  2. 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.

  3. 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
