Applied Psychology and Sociology: Behavioral Change

Overview of Behaviour Change in Clinical Practice

Behaviour change is defined as the process of modifying thoughts, emotions, or actions to achieve a desired outcome. This process is central to effective therapy for both clients and their caregivers, as it encourages consistent participation and the adoption of therapeutic strategies, ultimately supporting sustainable progress in skill development. In professional environments, behaviour change is applied in professional development through reflective practice to improve skills and habits, staying motivated for lifelong learning, and overcoming resistance to new techniques. With clients and caregivers, it focuses on encouraging engagement and adherence to therapy plans, motivating active participation, and promoting self-management. In team settings, it enhances communication, facilitates shared decision-making for cohesive goals, and influences others to adopt changes within a service.

Adherence and the Cognitive Hypothesis Model

Adherence refers to how well a client or caregiver follows agreed therapy recommendations and plans. Unlike "compliance," adherence implies active participation and shared decision-making. High adherence leads to better therapy outcomes, whereas poor adherence results in slower progress, missed goals, and disengagement. Key influences on adherence include client understanding, motivation, practical barriers, and the perceived value of the therapy.

The Cognitive Hypothesis Model of Adherence, proposed by Ley (1988, 1997), suggests that adherence is driven by three primary factors: Memory, Understanding, and Satisfaction. To improve adherence based on this model, practitioners should reinforce messages using multiple formats (written, verbal, and visual), regularly check for understanding by asking questions and linking tasks to the "bigger picture," and build rapport to ensure feedback and satisfaction. Sala (2002) also suggests that the use of light, self-effacing humour can relieve tension and improve the therapeutic relationship. Tools like the "Friends and Family Test" (FFT) are often used to gather feedback and measure satisfaction levels.

The Perceptions and Practicalities Approach (PPA)

Developed by Horne (2001), the Perceptions and Practicalities Approach divides the barriers to adherence into two categories. "Perceptions" relate to the beliefs an individual holds about the therapy or the problem, including questions such as "Is this worth doing?", "Will it actually help?", and "Is it safe?". "Practicalities" refer to real-world, objective barriers such as cost, time, transport, competing demands, fatigue, childcare, and physical access. Addressing adherence requires clinicians to manage both the internal beliefs of the client and the external constraints they face.

The Transtheoretical Model (TTM)

Also known as the Stages of Change model, the Transtheoretical Model was developed by Prochaska and DiClemente (1982). It is based on a synthesis of different psychotherapies and is considered "transtheoretical" because it is not specific to any one therapy but can be applied across many. The model posits that people move through identifiable stages of readiness, often in a non-linear or "spiral" fashion rather than a straight line. The five stages are:

1. Precontemplation: Not recognizing a need for change; individuals often underestimate the positive impact of change and overestimate the negatives.
2. Contemplation: Intending to change within the next $6\,\text{months}$; individuals weigh costs and benefits but are not yet ready for active change.
3. Preparation: Taking small steps toward change, such as seeking information or identifying professionals.
4. Action: Tangible change is occurring at the level of individual behaviours, thoughts, and relationships.
5. Maintenance: Active attempts to sustain change and prevent relapse.

Matching intervention strategies to the client’s current stage is pivotal. This requires careful listening and discussion to determine where the client sits on the continuum of readiness.

Health Action Process Approach (HAPA)

Proposed by Schwarzer (1992), HAPA is a stage model that emphasizes the role of self-efficacy in adopting and maintaining health behaviours. It divides behaviour change into at least two phases:

1. Motivational Phase (Pre-Action): The person evaluates the need for change and forms an intention. This is influenced by Risk Perception (awareness of risks), Outcome Expectancies (belief in benefits), and Task Self-efficacy (confidence in starting the change, based on Bandura, 1977; 2000).
2. Volitional Phase (Action & Maintenance): The person translates intention into behaviour. This is influenced by Action Planning (when, where, how), Coping Planning (anticipating barriers), Maintenance Self-efficacy (confidence in sustaining change), and Recovery Self-efficacy (belief in restarting after a lapse).

An example of reinforcing confidence through small successes involves a parent of a $35\,\text{year-old boy}$ named Simon (noting the transcript's specific age data) who has been stammering for $9\,\text{months}$. The therapist helps the parent develop self-efficacy statements, such as "I am confident I can do 'special time' every day even when I am feeling really tired," to increase belief in the ability to support therapy and enhance adherence.

Theory of Planned Behaviour (TPB)

Ajzen (1991) proposed that behaviour is driven by intention, which is shaped by three factors:

1. Attitudes: Personal beliefs about whether the behaviour is a good idea.
2. Subjective Norms: Perceived social pressure or expectations from others regarding the behaviour.
3. Perceived Behavioural Control (PBC): The perceived ease or difficulty of performing the behaviour, akin to self-efficacy.

Individuals may have the intention but fail to act if they lack control over certain behaviours. In a professional context, if an SLT named Sarah considers adopting a new evidence-based intervention for aphasia, her intention will depend on whether she thinks it is beneficial (Attitude), whether her team encourages it (Subjective Norms), and whether she feels she has the time and resources to implement it (PBC).

The COM-B Model

Developed by Michie et al. (2011), the COM-B model is a framework where Behaviour (B) occurs through the interaction of Capability, Opportunity, and Motivation. It forms the core of the Behaviour Change Wheel.

Capability (C): The physical and psychological ability. Physical Capability includes strength or dexterity (e.g., articulatory control). Psychological Capability involves knowledge and memory (e.g., understanding instructions).

Opportunity (O): External factors. Physical Opportunity includes resources and environment (e.g., quiet space for practice). Social Opportunity includes cultural norms and social support.

Motivation (M): Internal processes. Reflective Motivation involves conscious planning and goal setting. Automatic Motivation involves habits, emotions, or reinforcements (e.g., frustration leading to avoidance).

Case Study: David and Dysarthria

David is a $45\,\text{year-old}$ with moderate dysarthria following a traumatic brain injury (TBI) from a motorcycle accident. He lives with his wife, Emma, and sons aged $12$ and $15$. His therapy plan involves focusing on breathing and respiratory support, with daily $20\,\text{minute}$ practice sessions.

Using the COM-B model, David’s Capability is affected by reduced muscle control (Physical) and difficulties in planning speech movements (Psychological). His Opportunity includes access to materials and a quiet environment (Physical) and support from his family (Social). His Motivation is driven by his understanding of therapy Importance (Reflective) but challenged by frustration or embarrassment (Automatic).

For the Caregivers (Emma and sons), Capability involves their ability to facilitate communication. Opportunity involves the time and resources they have to support David. Motivation is driven by their belief in recovery (Reflective) and their emotional bond with David (Automatic).

The Speech and Language Therapist (SLT) must also have the Physical skills and Psychological knowledge (Capability), access to tools and professional networks (Opportunity), and a commitment to client-centered care (Motivation) to ensure the intervention succeeds.

Ethical Considerations in Behaviour Change

Behaviour change techniques are powerful and must be applied with respect for autonomy, dignity, and best interests. Key questions include: Is the change for the client's benefit or others' convenience? Has the individual consented? Are we respecting neurodiversity and cultural differences? Are there unintended consequences, such as emotional distress?

Applied Behaviour Analysis (ABA) is a high-profile example of these ethical debates. While it reinforces "desirable" behaviours and is used as an early intervention for autistic individuals, it is controversial. Concerns include the use of compliance-based strategies that might override autonomy, the goal of "normalisation" (e.g., reducing stimming or eye-contact avoidance) versus functional communication, and the impact of intensive programs that can involve up to $40\,\text{hours per week}$ starting as early as $18\,\text{months}$ old. Organizations like the Autistic Self Advocacy Network (ASAN) argue that prioritising social acceptance over individual well-being can be harmful.

SMART Goals for Professional Development

To facilitate the adoption of evidence-based practice and lifelong learning, professionals can use SMART goals:

• Specific: Clearly define the skill.
• Measurable: Track progress (e.g., "Complete $10\,\text{CPD hours}$ on AAC").
• Achievable: Realistic within workload.
• Relevant: Aligns with career goals.
• Time-bound: Set a deadline for accountability.
