Study Notes
Why Theory is Important
- Theory provides an explanatory system for 'what' and 'how' health behaviours occur.
- It helps identify targets for intervention and allows for hypothesis testing.
- Theory-based health promotion campaigns are more effective than atheoretical campaigns (Noar, 2006; Webb et al., 2010).
- Evaluation of interventions using theoretical approaches is also more efficient and cost-effective (French et al., 2012; Prestwich et al., 2015; Stead et al., 2005).
Basis for Intervention
- Intervening on health behaviour involves matching theoretical determinants with specific change methods.
- The intervention mapping approach (Kok et al., 1998, 2004, 2016) links psychological variables with behaviour change techniques.
Behaviour Change Techniques/Methods
- A behaviour change technique is an observable, replicable, and irreducible component of an intervention (Michie et al., 2013)
- These are the 'tools' that directly change behaviour by targeting specific determinants.
- They can be used independently or in conjunction with other techniques.
Methods Used to Change Behaviour in Theory-Based Interventions
- Common methods include:
- Information provision
- Skill building
- Persuasion techniques
- Planning
- Social encouragement
- Goal setting
- Motivation enhancement
- Self-monitoring
Motivational Interviewing
- A non-confrontational approach, particularly effective for individuals reluctant to change (Miller and Rollnick, 2002).
- Rooted in self-determination theory, emphasising autonomy and choice.
- Goal is to increase motivation to consider change, not dictate how to change.
- Addresses ambivalence and creates cognitive dissonance to prompt self-reflection.
- Key questions:
- "What are some of the good things about your present behaviour?"
- "What are the not-so-good things about your present behaviour?"
- Other elements:
- Expressing empathy
- Avoiding arguments
- Rolling with resistance
- Considering disadvantages of current behaviour
- Highlighting advantages of change
- Evoking intention to change
- Supporting self-efficacy
Information Provision and Communication Persuasion
- Providing information to increase knowledge and promote health literacy.
- Influences outcome expectancies, personal relevance, attitudes, self-efficacy, and subjective norms.
- Example: Fact sheets or health education campaigns.
Attitude Change
- Interventions based on the Theory of Planned Behaviour (TPB) should target underlying beliefs (Hagger et al., 2002).
- For attitude change, focus on salient behavioural beliefs (Ajzen, 1991).
- Elicit these beliefs through open-ended surveys or interviews (Ajzen & Fishbein, 2003).
- Persuasive communications should incorporate these beliefs to create a rationale for behaviour change (Ajzen & Manstead, 2007).
Strategies for Behaviour Change
- Motivational interviewing interventions
- Information provision and communication persuasion
- Cognitive strategies
- Confidence and self-efficacy interventions
- Problem-solving approaches
- Goal setting interventions
- Planning and implementation intentions
- Monitoring interventions
- Imagery and mental simulation interventions
- Environmental interventions
- Public health interventions
- Using new technology
Information Provision and Health Literacy
- Information provision increases health literacy, leading to better attitudes towards target behaviors and potential behavior change.
- Information can provide personal relevance, demonstrating the direct impact of behavior change on personal outcomes.
- Information provision alone is not the most effective strategy for behavior change.
- The correlation between information and behavior change is weak and primarily influences intentions.
Effective Strategies for Behavior Change
- Messages should include self-efficacy elements, providing information on how to perform the desired behavior.
- Normative influences can be highly effective, highlighting the prevalence of successful behavior change within a specific group.
- The majority of behavior change models emphasize the importance of attitude in influencing behavior.
The Theory of Planned Behavior
- Interventions targeting attitudes should focus on underlying beliefs responsible for attitude change.
- Behavioral beliefs, including advantages and disadvantages of the target behavior, are crucial to consider.
- Interventions should address both the positive and negative beliefs associated with a behavior.
Mass Media Campaigns
- Mass media campaigns are a popular approach but effectiveness is questionable for single initiatives.
- Coordinated, repeated campaigns are more effective than single interventions.
- Evaluation of mass media campaigns is essential but often neglected.
Increasing the Effectiveness of Mass Media Campaigns
- Multiple interventions increase the likelihood of success, particularly with one-off or episodic behaviors.
- Access to key services and supportive policies facilitate the transition from motivation to change.
- Isolating the independent effects of mass media campaigns is challenging, but they can contribute to population health change.
The Elaboration Likelihood Model (ELM)
- Suggests two routes to processing information: central and peripheral.
- Central processing, characterized by motivation and comprehension, leads to stronger attitude change.
- Peripheral processing, lacking motivation or understanding, results in weaker attitude change.
- Maximizing the credibility and attractiveness of the message source is crucial.
The Use of Fear in Mass Media Campaigns
- A popular approach but often ineffective in driving behavior change.
- Protection Motivation Theory emphasizes both threat appraisal and individual efficacy.
- Fear-inducing messages are most effective when combined with high baseline efficacy or strong efficacy-enhancing elements.
Information Framing
- Positive framing stresses the positive outcomes of action, enhancing information processing, particularly when time is limited.
- Negative framing focuses on the negative outcomes of inaction, making the message more memorable.
- Evidence regarding the effectiveness of framing is conflicting, with both positive and negative framing showing success in some cases.
Targeting the Audience
- Mass media campaigns lack specific focus, making audience targeting more effective.
- Targeting can be based on various factors including demographics, behavior, and psychological characteristics.
- Engaging the target group in co-creation of messaging can increase relevance and effectiveness.
Mass Media and Behavior Change
- Central vs. Peripheral Cues: Central cues focus on information, while peripheral cues rely on factors like source credibility or attractiveness. Central cues are more effective for individuals highly involved with the issue. Peripheral cues are stronger for those with lower involvement.
-
Effectiveness of Fear Arousing Messages: Campaigns using fear are often ineffective. People tend to tune out. To be successful, fear-based messages should:
- Instill a sense of severity if behavior doesn't change
- Emphasize the individual's ability to control the feared outcome
- Include self-efficacy messages.
- Information Framing: Framing messages either positively (stressing benefits of action) or negatively (highlighting negative consequences of inaction). Research shows conflicting results, suggesting further exploration of framing strategies is necessary.
-
Targeting the Audience: Mass media campaigns are most effective when specifically targeted to a known audience.
- Consider: demographics, socioeconomic status, psychological factors, and motivations.
- Co-creation of messages with the target group is crucial.
Cognitive Strategies for Behavior Change
-
Cognitive Therapy: This therapy centers around the idea our thoughts regulate our behavior, shaping feelings, motivations, and actions. It aims to:
- Treat beliefs as hypotheses, not facts
- Encourage individuals to examine alternative perspectives
- Develop new behavioral response based on revised thinking.
-
Identifying Irrational Beliefs (CBT): Irrational beliefs are unrealistic and distorted thoughts leading to distress and unhealthy behaviors.
- They often involve absolutes (e.g., "I must be perfect.")
- Through Socratic dialogues, individuals question the validity of these beliefs.
-
Confidence and Self-efficacy: Information and cognitive interventions are most effective with individuals who have the skills and confidence to apply them.
-
Strategies to enhance self-efficacy:
- Modeling: Observing relevant tasks performed by others
- Practice: Graded skills development
- Verbal persuasion: Encouragement and assurances of capability
- Self-talk: Positive affirmations (e.g., "just do it")
-
Strategies to enhance self-efficacy:
-
Vicarious Learning: Learning from observing others perform tasks. Three types:
- Live model: Direct demonstration
- Verbal instructional model: Descriptions or explanations
- Symbolic model: Real or fictional characters in media.
Increasing Confidence and Self-efficacy
-
"This Girl Can" Campaign: Aimed at increasing self-efficacy among women, addressing barriers to physical activity.
- Featured women of diverse ages and body shapes, promoting a range of activities.
-
Interventions Focus: Addressing both skills and self-efficacy.
- Examples: Cooking skills intervention, safe sex practices.
Changing Normative Beliefs
-
Strategies:
- Provide information about others' behavior
- Highlight others' approval of desired behavior
- Encourage social comparison opportunities.
Social Support
- Social support essential for sustained behavior change.
Building Confidence and Self-Efficacy
- Confidence and self-efficacy can be built up through various means, including teaching skills and solutions to problems.
- Examples include cooking skills interventions and safe sex practices for adolescents.
- Interventions can be delivered individually or on a population level.
Normative Beliefs
- Normative beliefs can significantly influence people's behavior, especially for adolescents and parents.
- Strategies to change normative beliefs include:
- Providing information about others' behavior, making it the norm.
- Highlighting approval from others for performing the behavior.
- Encouraging social comparison to see others successfully perform the behavior.
Social Support
- Behavior contracts can be helpful, outlining goals, rewards, and steps to be taken.
- Social support can be provided by health professionals, family, or friends.
- It can take various forms, including emotional encouragement and tangible assistance.
Cognitive-Behavioral Therapy (CBT)
- CBT is a form of psychotherapy addressing thoughts and behaviors.
- It's effective in treating issues like depression, anxiety, trauma, and addictions.
- CBT focuses on identifying and challenging irrational beliefs, often automatic thoughts.
- It helps modify behaviors that reinforce negative thought patterns.
- Core beliefs, deeply held beliefs about oneself and the world, influence how we interpret situations.
- CBT aims to change unhelpful core beliefs.
Problem-Solving Approaches
- Developed by Egan (2006), this approach focuses on "how" to change, not "whether" to change.
- It's problem-oriented and focused on the "here and now", making it suitable for those wanting to change immediately.
- It consists of three phases:
- Problem exploration and clarification.
- Goal setting.
- Facilitating action.
Problem-Solving: Example - Smoking Cessation
- Smoking involves conditioned responses to cues and a physiological need for nicotine.
- Quitting can involve dealing with withdrawal symptoms, coping with cues, and resisting cravings.
- Strategies include:
- Coping with cues to smoking.
- Reducing the likelihood of giving in to cravings.
- Managing withdrawal symptoms with nicotine replacement therapy (NRT).
Goal Setting Interventions
- Developed by Aiken, this approach focuses on the issues at hand and encourages change.
- It involves three phases:
- Problem exploration and clarification.
- Goal setting.
- Facilitating action.
Goal Setting: Example - Smoking Cessation
- Individuals need to deal with the loss of mood alteration, withdrawal symptoms, and cravings triggered by cues.
- Strategies include:
- Avoidance strategies (e.g., avoiding smokers, not carrying money for cigarettes).
- Coping strategies (e.g., focusing attention away from cravings, reframing withdrawal symptoms as recovery signs).
Goal Setting: SMART Goals
- SMART goals are specific, measurable, achievable, relevant, and timely.
- Specific: Clear and detailed, addressing "what," "where," "when," and "with whom."
- Measurable: Easy to track progress.
- Achievable: Set within reach to avoid undermining self-efficacy.
- Relevant: Personally meaningful and important for achieving a desired change.
- Timely: Having a set timeframe to maintain motivation and encourage action.
Implementing Plans and Intentions
- We sometimes fail to translate intentions into action due to:
- Failure to start.
- Becoming derailed from goals.
- Implementation intentions (II) involve an "if-then" approach, linking a specific situation with an action.
- This creates a mental association that promotes goal initiation and can help resist distractions.
Monitoring Interventions
- Effective monitoring interventions involve:
- Setting a suitable goal for monitoring.
- Designing a monitoring strategy.
- Processing the obtained information.
Self-Monitoring
- Habits develop through consistent behavior practiced in the same context, triggered by a cue, and reinforced over time.
Habits: Dos and Don'ts
-
Dos:
- Use trigger events and reminders.
-
Don'ts:
- Rely on external rewards or motivation.
- Rely on technology.
- Use time-based cues (routine-based are better).
- Provide multiple plans.
- Use negating implementation intentions (e.g., "If I am sad, then I will not eat chocolate").
Applying Self-Monitoring with Individuals
- Create a plan: Identify cues that trigger the behavior, develop a strategy, and use environmental prompts.
- Monitor progress: Track behaviors and adjust strategies as needed.
Example - Promoting Habits: Physical Activity in the Workplace
- Habits play a role in physical activity promotion.
- An implementation intention example could be: "If it's 2 p.m., then I'll go for a 10-minute walk."
- This mentally links a cue (2 p.m.) to the desired action (walking) and promotes the action when encountered.
If-Then Plans
- If-then plans are a simple yet effective strategy to bridge the intention-behavior gap.
- They involve anticipating potential obstacles and deciding how to handle them beforehand.
- Example: "If I am out with friends and get asked what I want to drink, then I will ask for water." (Goal: Drink eight glasses of water daily)
- Repetition and practice help make the plan automatic and effortless.
Environmental Influences on Health Behaviour
-
Cues to action:
- These can either decrease unhealthy behaviors (e.g., larger warnings on tobacco products) or increase healthy ones (e.g., posters encouraging stair use).
- They can also act as reminders for unhealthy behaviors (e.g., advertisements, movies).
-
Minimizing the costs of healthy behavior:
- The environment can facilitate or inhibit participation in health-related behaviors.
- Healthy Cities movement (WHO) aims to design cities that promote physical & mental health (e.g., green spaces).
- Examples:
- Linegar et al. (1991) manipulated physical (cycle paths, exercise equipment) and organizational (release time) environments in a naval base to encourage physical activity.
- Marketing campaigns promoting walking groups and community exercise classes.
- Environments that inhibit healthy behavior:
- Poor street lighting, busy roads, high levels of pollution.
-
Increasing the costs of unhealthy behavior:
- Making unhealthy behavior difficult (e.g., through pricing or availability) acts as a barrier.
- Examples:
- Increased taxation on tobacco (Hu et al., 1995) found a 25% tax increase resulted in a significant decrease in cigarette sales compared to media influences.
- Restricting the number of alcohol outlets increases travel time & effort needed to purchase, acting as a deterrent.
-
Bans:
- Smoke-free areas (Heloma & Jaakalo, 2003), resulting in reduced secondhand smoke exposure and lower smoking prevalence in workplaces.
- Banning smoking in public places (e.g., restaurants and bars in Texas, US) had no reported negative impact on profits or consumption, and may even have positive effects on health.
Habit Formation
- Habits are formed when a certain behavior is practiced repeatedly in the same context, in response to a cue, and is reinforced over time.
-
Event-based cues:
- Using existing habits as triggers for new behaviors (e.g., brushing your teeth as a cue to start flossing).
- More effective but slower to develop.
- Monitoring is needed during this process.
-
Time-based cues:
- Using reminders like SMS notifications to support behavior repetition.
- May hinder automaticity as people become reliant on the reminder instead of generalizing to other cues.
-
If-then plans for cues:
- Example: "If I see or smell chocolate, then I will follow my diet goal."
-
Do's and Don'ts in habit formation:
-
Do's:
- Support trigger events (e.g., use phone ringing as a cue to stand up and pace).
- Use reminders to support implementation intentions.
-
Don'ts:
- Rely on external rewards as they might not sustain behavior once removed.
- Focus on external motivation – intrinsic motivation leads to long-term behavior maintenance.
- Rely on technology, favor event-based cues over time-based ones.
- Provide multiple plans – start simple and build on existing behaviors.
- Use negating plans (e.g., "If I am sad, then I will not eat chocolate") as they might reinforce the unwanted association.
-
Do's:
Applying If-Then Plans to Individuals
- Develop a plan using the if-then strategy or a more detailed action plan approach.
-
Action Plan:
- Identify cues to action linked to the target behavior (e.g., after lunch, after brushing teeth, before bed).
- Use the environment as prompts or cues (e.g., social distancing markers).
- Restructure the environment to act as prompts (e.g., hat rack on the door, mask hooks).
-
Example Intervention:
- Habit-forming intervention for sedentary office workers:
- Identify cues in the environment that could encourage movement.
- Develop an if-then strategy or an action plan.
- Monitor progress over time to strengthen habits.
