Developing Exercise Interventions pt. 1 Dr. Jeremy Walsh KINESIOL 3H03 Asynchronous Lecture #6 mcmaster.ca  Lecture Outline and Objectives Examine approaches to developing exercise interventions Systematic Approach to developing interventions 4 stages… Today we will focus on: Stage 1: Understanding the behaviours Stage 2: Identifying intervention options Approaches to Developing Exercise Interventions ISLAGIATT – It Seemed Like A Good Idea At The Time Intervention designed without establishing a thorough understanding of the influences on physical activity for a specific population in a specific context Interventions designed without using theory. Loading… Stages for Developing an Exercise Intervention Stage 1: Understand the behavior Stage 2: Identify intervention options Stage 3: Identify intervention content and implementation options Stage 4: Evaluate the impact of the intervention Stage 1: Understand the Behaviour Step 1 – Identify Target Behaviour and Population: What specific physical activity behaviour are you trying to change? (Target Behaviour) Who is the specific target population / individual of the intervention? (Target Population) Examples Loading… Increasing active transportation to/from school in elementary school-aged children Breaking-up sitting with activity breaks in office workers Important target the BEHAVIOUR, not the OUTCOME  Stage 1: Understand the Behaviour Step 2 – Conduct a Behavioral Analysis and Diagnosis: Goal – identify what factors need to change in order for behaviour to occur Capability: Does the individual have the physical strength, knowledge, skills, and stamina to perform the behavior? Opportunity: Does the individual have a supportive physical and social environment to perform the behavior? Motivation: Does the individual want to do the behavior more than they want to do another competing behavior?  Stage 1: Understand the Behaviour Step 2 – Conduct a Behavioral Analysis and Diagnosis: Goal – identify what factors need to change in order for behaviour to occur Capability: Physical – skills, stamina, strength Psychological – mental capacity, knowledge Opportunity: Social – influences, social cues, social norms Physical – time, resources, built environment Motivation: Reflective – planning, intentions, evaluating outcomes Automatic – emotional reactions, impulses, desires COM-B Case Study Hashim has never worked out on a regular basis but thinks that lifting weights would improve his self-confidence He bought a gym membership and successfully scheduled exercise into his daily routine, but… When he tried a workout, he felt intimidated and self-conscious b/c he didn’t know how to use the equipment Hashim’s friend Jacob is an experienced weight lifter and offered to workout with Hashim and teach him some exercises  ACTIVITY AND SCENARIO FOR BEHAVIOURAL ANALYSIS COM-B Factors What needs to happen to PA to occur? Is there a need for change? Physical Capability CAPABILITY Psychological Capability Social Opportunity OPPORTUNITY Physical Opportunity Reflective Motivation MOTIVATION Automatic Motivation BEHAVIOURAL DIAGNOSIS: based on assessment state what factor(s) need to be targeted for PA to occur Stage 2: Identify Intervention Options Step 3: Select Intervention Functions - intervention activities that are designed to change behaviour by making change to capability, opportunity, and/or motivation  IMPORTANT Goal: to get college students to perform strength training Linking COM-B with Intervention Functions Stage 2: Identify Intervention Options Step 4: Select Policy Categories - Policy categories are approaches that can be used by stakeholders to support or establish interventions Stakeholder = people with interest or concern in something (context matters) Workplace PA Intervention – employees, employers, insurance providers, physicians, investors PA intervention in remote indigenous school – parents, children, elders, community and cultural leaders, physicians, teachers Exercise classes for people with dementia Opening up Main St. to pedestrians and cyclists only on weekends Policy Categories 7 policy categories and examples for promoting strength training in colleges students *Feasibility matters!! Need to take into account what categories you can influence Linking Intervention Functions w/ Policy Categories  The Behaviour Change Wheel Putting Stage 1 & 2 Together Using this approach, we can: 1. Understand the target behaviour 2. Consider the full range of options available to you 3. Have a systematic approach for selecting behaviour change techniques (Michie et al., 2014, 2011)
