9.2 Social and Behavioral Aspects of Practice
Key Takeaways
- The Health Belief Model explains behavior through perceived susceptibility, severity, benefits, barriers, cues to action, and self-efficacy.
- The Transtheoretical (Stages of Change) Model describes six stages — precontemplation, contemplation, preparation, action, maintenance, and relapse — each matched to a different pharmacist intervention.
- Adherence is approximately 50% in chronic conditions and 70% in acute conditions; the Proportion of Days Covered (PDC) at 80% is the standard pharmacy-claims adherence quality measure.
- Cultural competence progresses along a continuum from cultural destructiveness to cultural proficiency; cultural humility emphasizes lifelong self-evaluation and redressing power imbalances.
- Religious beliefs — Ramadan fasting, Halal and Kosher dietary restrictions, Jehovah's Witnesses and blood products — can shape medication choices and require respectful, individualized accommodation.
9.2 Social and Behavioral Aspects of Practice
Quick Answer: Patient behavior is shaped by the Health Belief Model (perceived susceptibility, severity, benefits, barriers, cues to action), the Transtheoretical (Stages of Change) Model, Social Cognitive Theory, and the Health Action Process Approach (HAPA). Pharmacists improve outcomes by measuring adherence objectively and matching interventions to the patient's stage and self-efficacy. Cultural competence — moving from cultural destructiveness toward proficiency, practicing cultural humility, and addressing implicit bias and health disparities — is tested alongside religion-related care considerations.
Health Belief Model
The Health Belief Model (HBM) explains why individuals act (or don't act) on health information. Five constructs drive behavior:
- Perceived susceptibility — "How likely am I to get this disease?"
- Perceived severity — "How serious would it be?"
- Perceived benefits — "Will the recommended action help?"
- Perceived barriers — "What costs, side effects, or hassles stand in the way?"
- Cues to action — triggers that prompt behavior (symptoms, reminders, a family member's diagnosis)
Self-efficacy was added to the model in 1988 and reflects the patient's confidence in performing the behavior. A pharmacist who understands HBM can target counseling: a patient who skips statins because they feel fine has low perceived susceptibility, not laziness. Address the perceived barrier (cost, pill burden), highlight the benefit, and provide a cue (a refill reminder).
Sick-Role and Illness Behavior
Talcott Parsons' sick role describes the social expectations of an ill person: they are exempt from normal responsibilities, they must want to get well, and they must seek technically competent help. Illness behavior is how a person monitors symptoms, interprets them, and seeks care — distinct from disease, which is the biomedical pathology. Help-seeking behavior is shaped by culture, access, and prior experience with the health system.
Behavior Modification Theories
Stages of Change (Transtheoretical Model)
Developed by Prochaska and DiClemente, the model describes six stages through which people progress when changing behavior. Pharmacists match the intervention to the stage rather than defaulting to "just do it."
| Stage | Patient State | Pharmacist Intervention |
|---|---|---|
| Precontemplation | No intent to change (often unaware of problem) | Provide information, raise awareness, avoid arguing |
| Contemplation | Ambivalent; weighing pros and cons | Discuss pros and cons, use decisional balance |
| Preparation | Intends to act within 30 days; small steps taken | Set a quit date, build a plan, identify supports |
| Action | Overtly modifying behavior (< 6 months) | Praise effort, troubleshoot barriers, simplify regimen |
| Maintenance | Sustained change (> 6 months) | Reinforce progress, anticipate relapse triggers |
| Relapse | Slips back to old behavior | Normalize as part of the cycle; re-enter at contemplation or preparation |
Social Cognitive Theory
Albert Bandura's Social Cognitive Theory (SCT) centers on self-efficacy (the belief in one's ability to perform a behavior), observational learning (modeling others), and reciprocal determinism (person, behavior, and environment influence each other). Pharmacists build self-efficacy by setting small achievable goals, demonstrating skills (inhaler technique with a return demonstration), and arranging peer models.
Health Action Process Approach (HAPA)
The Health Action Process Approach (HAPA) distinguishes a motivation (intention) phase from a volition (action) phase. Forming an intention is necessary but not sufficient; the action phase requires action planning (when, where, how) and coping planning (what to do when barriers arise). This explains why patients who "intend" to take medication still miss doses — the intention-action gap.
Patient Adherence
Compliance is provider-centric ("follow my orders"); adherence is collaborative ("follow the agreed plan"); concordance is shared decision-making that respects patient values. FPGEE wording favors adherence.
Adherence rates run roughly 50% for chronic conditions and 70% for acute conditions — a finding the WHO has called the most modifiable factor in chronic disease outcomes.
Predictors of Non-Adherence
- Regimen complexity (multiple daily doses, multiple drugs)
- Cost and lack of insurance
- Adverse effects (e.g., statin myalgia, SSRI nausea)
- Low health literacy and limited English proficiency
- Depression and cognitive impairment
- Poor patient-provider relationship and inadequate counseling
Measuring Adherence
Self-report is cheap but overestimates adherence. Pill counts and pharmacy refill data (the Proportion of Days Covered, PDC ≥ 80% is the standard quality measure used in Medicare Star Ratings) are objective but don't confirm ingestion. Electronic monitoring (e.g., MEMS caps with timestamped openings) is the gold standard for research but costly. Biomarkers (serum drug levels, HbA1c, blood pressure) confirm physiologic effect but are invasive and expensive.
Adherence Interventions
- Packaging: blister packs, pill organizers, multi-dose strip packaging
- Reminders: phone alarms, app notifications, SMS programs
- Medication Therapy Management (MTM): comprehensive review with a Personal Medication Record
- Simplified regimens: once-daily formulations, fixed-dose combinations
- Behavioral: reinforcement, contracts, counseling matched to stage
Cultural Awareness
The cultural competence continuum (Cross et al.) progresses through six points: cultural destructiveness → cultural incapacity → cultural blindness → cultural pre-competence → cultural competence → cultural proficiency. Pharmacists should aim for competence and aspire to proficiency — ongoing learning, not a checkbox.
Cultural humility complements competence: a lifelong commitment to self-evaluation, redressing power imbalances, and recognizing that the patient is the expert on their own culture.
Health Disparities and Implicit Bias
Health disparities are differences in health outcomes systematically tied to social, economic, or environmental disadvantage. They appear across race and ethnicity, primary language, socioeconomic status, geography, and disability status. Implicit bias — unconscious attitudes that affect understanding and action — can drive disparities even when explicit intent is equitable. Strategies include self-awareness, standardized protocols, and perspective-taking exercises.
Cultural Frameworks
Arthur Kleinman's Explanatory Models ask a series of questions (e.g., "What do you call your problem? What do you think caused it?") to elicit the patient's own framework. The cultural formulation (from DSM-5) integrates cultural identity, explanations, psychosocial stressors, and the patient-clinician relationship.
Religion and Health
Religious beliefs can shape medication decisions: Halal and Kosher dietary restrictions may affect gelatin capsule choice; Ramadan fasting can require adjusting oral medication timing (e.g., switching to once-daily dosing timed to suhoor or iftar); Jehovah's Witnesses refuse blood products; many traditions have specific end-of-life beliefs (withholding or withdrawing treatment, autopsy restrictions) and faith healing expectations. Pharmacists should ask respectfully, document preferences, and accommodate when clinically safe.
