Developing Physical Activity Interventions: Stage 1 and 2
Lesson Objectives and Overview
- The course focuses on developing physical activity interventions as part of HHP:3045.
- The intervention design process is divided into four distinct stages:
- 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.
- Specific research examples are utilized to illustrate these stages:
- Connell et al., 2015.
- Whitaker et al., 2022.
The ISLAGIATT Principle: What to Avoid
- ISLAGIATT stands for: "It Seemed Like A Good Idea At The Time."
- This principle describes interventions designed without a fundamental understanding of the influences on health behavior (such as physical activity) for a specific population in a specific context.
- Common pitfalls of ISLAGIATT-based interventions include:
- Not using established theory.
- Failing to consider the specific context of the target population.
- Resulting in small effect sizes.
- Ineffectiveness leading to a significant waste of time, money, and resources for all involved stakeholders.
The Alternative: The Four-Stage Process
- Stage 1: Understand the Behavior
- Step 1: Identify target population and behavior (The focus of this specific lecture).
- Step 2: Conduct a behavioral analysis and diagnosis.
- Stage 2: Identify Intervention Options
- Step 3: Select Intervention Functions.
- Step 4: Select Policy Categories.
- Stage 3: Identify Content and Implementation Options
- Step 5: Select behavior change techniques (BCTs).
- Step 6: Select modes of delivery.
- Stage 4: Evaluation
- Step: Evaluate and iterate the intervention using evaluation frameworks.
Stage 1: Understand the Behavior
Step 1: Identify Target Population and Behavior
- Defining the Group: Clearly specify the group whose behavior is the target for change.
- Defining Behaviors: Be specific about the behaviors to be changed, answering:
- What behavior?
- When does it occur?
- Where does it occur?
- How often does it happen?
- With whom is the behavior performed?
- Stakeholder Involvement: It is critical to involve stakeholders, defined as people who have an interest or concern in the intervention.
- Example: If employees are trying to become more active, stakeholders include the company employees, management, and health insurance/care providers.
Step 2: Conduct a Behavioral Analysis and Diagnosis
- The COM-B Model: Used to understand factors influencing the target behavior, including barriers and facilitators. The components are:
- Capability: Includes Physical capability (skill, stamina) and Psychological capability (knowledge, mental skills). Similar to the "Planning" aspect of behavior.
- Opportunity: Includes Physical opportunity (environmental supports/barriers) and Social opportunity (social norms, relatedness). Similar to the Self-Determination Theory (SDT) concept of "Relatedness" and the Theory of Planned Behavior (TPB) concept of "Subjective Norm."
- Motivation: Includes Reflective motivation (intentions, evaluations) and Automatic motivation (emotions, drives, habits). Reflective motivation is similar to TPB "Intention," while Automatic motivation relates to the "Motivational Continuum" in SDT.
- The goal is to outline what factors need addressing for behavior change to occur.
Real-World Example: Bike-to-Work Intervention (Exhibit 5.3)
- Behavioral Analysis Findings:
- Physical Capability: The population must have skill and stamina. Diagnosis: No change needed; employees indicated they have the skills.
- Psychological Capability: The population must know how to ride to work. Diagnosis: Change needed; employees need to know the safest and fastest routes.
- Physical Opportunity: Access to a bike, helmet, and time. Diagnosis: No change needed; employees have bikes and find it reduces commuting time.
- Reflective Motivation: Must see benefit and want to cycle. Diagnosis: No change needed; employees want to cycle and see benefits.
- Automatic Motivation: Positive emotional reaction, habit, or desire. Diagnosis: Change needed; employees indicated they are afraid to cycle and do not do it habitually.
- Intervention Target: The final diagnosis concluded the intervention must target psychological capability and automatic motivation.
Stage 2: Identify Intervention Options
Step 3: Selecting Intervention Functions
- Intervention Functions are activities within the intervention designed to change behavior by altering capability, opportunity, or motivation.
- Intervention Functions Definitions and Examples:
- Education: Increasing knowledge or understanding.
- Persuasion: Using communication to induce positive or negative feelings.
- Incentivization: Creating an expectation of reward.
- Coercion: Creating an expectation of punishment or cost.
- Training: Imparting skill (e.g., an athlete teaching a class).
- Restriction: Using rules to reduce opportunity to engage in competing behaviors (e.g., rules regarding screen time).
- Environmental Restructuring: Changing the physical or social context (e.g., building a new gym or adding equipment at parks).
- Modeling: Providing an example for people to aspire to or imitate.
- Enablement: Increasing means or reducing barriers to increase capability or opportunity beyond other functions (e.g., providing resources to reduce barriers).
Step 4: Selecting Policy Categories
- Policy categories are approaches used by stakeholders to support intervention implementation.
- Policy Categories Definitions and Examples:
- Communication/Marketing: Using print, electronic, or broadcast media.
- Guidelines: Documents recommending or mandating practice (e.g., putting specific guidelines in place).
- Fiscal Measures: Using the tax system to manage costs (e.g., taxing cigarettes or providing tax breaks for health initiatives).
- Regulation: Establishing rules or principles for behavior (e.g., requiring gym members to sign a paper agreeing to promote exercise).
- Legislation: Making or changing laws (e.g., a law requiring all universities to provide access to strength training devices).
- Environmental/Social Planning: Designing/controlling the physical or social environment.
- Service Provision: Delivering a service (e.g., providing free strength classes to all students).
Research Case Study: O’Connell et al. (2015)
- Identifying Target Population and Behavior:
- Focus: Sedentary behavior (SB) as a risk factor for poor health, independent of general physical activity.
- Identified Behavior: Breaking prolonged sitting with bouts of standing and light movement improves health.
- Context: Work sites are logical intervention points as many jobs are desk-bound.
- Evidence: Sit-stand desks reduce occupational and leisure sitting time.
- Intervention Strategy: Known as the SMArT Work intervention strategy.
Research Case Study: Whitaker et al. (2022) - INSPIRE
- Program Name: INSPIRE (INcreasing Steps in PREgnancy).
- Project Address: 225 S. Grand Avenue, 102 Field House, Iowa City, IA 52242.
- Contact Phone: 3193357907.
- Target Population and Behavior:
- Physical activity (PA) is safe for mother and baby with many benefits, yet pregnant women are less likely to meet PA guidelines.
- High sedentary behavior increases the risk of hypertensive disorders of pregnancy, independent of PA.
- Behavioral Analysis and Diagnosis Survey Areas: Participants were asked to rank interests/agreement on:
- Benefits of PA for themselves and the baby.
- Safe and unsafe activity types.
- Managing PA when tired, nauseous, or busy (fitting into schedule).
- Sticking with PA despite disruptions or low motivation.
- Decreasing sitting time and home activity ideas.
- Using monitoring devices (Fitbit, pedometers) and health coaches.
- Walking games via smartphone apps and walking groups.
- Partner involvement and social media sharing.
- DVDs or online videos for use at home.
- Post-baby program continuation.
- Study Contacts and Schedule: 12 sessions conducted via Zoom or telephone:
- Session 1 (Weekly): PA benefits and safety.
- Session 2 (Weekly): PA tips and resources.
- Session 3 (Weekly): Targeting motivation.
- Session 4 (Weekly): Making time for PA.

- Session 8 (Bi-monthly): Long-term maintenance.
- Session 9 (Bi-monthly): Barriers to PA.
