ADHERENCE Theoretical models: Behavioral model,Self-efficacy theory Theory of reasoned action and planned behavior, and transtheoretical model. • Behavioral Therapy – Positive reinforcement – Negative reinforcement – Punishment • Self-efficacy Theory • Albert Bandura proposed a social cognitive theory. • Individuals use their cognitive processes for self-regulation. • Human action results from an interaction of behavior, environment and person factors, especially cognitions. • Bandura referred this interactive triadic model as reciprocal determinism. • Denoted by triangle. • An important component of person factor is self-efficacy, people’s beliefs in their capability to exercise some measure of control over their own functioning and over environmental events. • Self-efficacy can be acquired, enhanced or decreased in four ways; performance, vicarious experience, verbal persuasion and physiological arousal states i.e anxiety which decrease self-efficacy. • Adherence is the extent to which a person is able and willing to follow medical and health advice. • In order to profit from adherence; first, the advice must be valid and second ,patient must follow advice. • Six ways of measuring adherence; ask the practitioner, ask the patient, ask other people, monitor medical usage, examine biochemical evidence and use a combination of these procedures. • Asking the practitioner is usually the poorest choice. • No one of these procedure is both reliable and valid. • FACTORS PREDICT ADHERENCE • Severity of the disease • Treatment characteristics; side effects and complexity of treatment. • Personal factors; age, gender, personality patterns, emotional factors, personal beliefs. • Environmental factors; economic factors, social support. • Cultural norms. • Practitioner- patient interaction; verbal communication, practitioner’s personal characteristics. – HOW CAN ADHERENCE BE IMPROVED? • Knowing the barriers. • Four approaches; providing prompts, tailoring the regimen, implementing the regimen gradually, and making a contingency contract.
