概要	The Illness Perception Questionnaire—Revised (IPQ-R) is a 70-item measure (brief version: 38 items) developed by Moss-Morris and colleagues (2002) to assess how individuals perceive and cognitively represent their illness. Based on Leventhal's Common Sense Model of illness representation, the IPQ-R measures nine dimensions: Identity (symptoms associated with the illness), Timeline (perceived duration and course), Consequences (expected impacts on functioning and quality of life), Personal Control (perceived ability to influence the illness), Treatment Control (perceived effectiveness of medical treatment), Illness Coherence (understanding of the illness), Concern (worry about the illness), Emotions (emotional responses to the illness), and Causation (attributed causes of illness). These cognitive representations profoundly influence coping behaviors, treatment adherence, emotional well-being, and actual health outcomes. The IPQ-R is widely used in chronic disease management (diabetes, asthma, cardiac disease, arthritis), mental health, rehabilitation, and health psychology research to understand illness-specific beliefs and to guide psychosocial interventions.	The Patient Activation Measure (PAM) is a 13-item self-report questionnaire developed by Hibbard and colleagues (2004) to assess the degree to which patients understand their role in managing their health, have confidence in their ability to engage in self-care, and take action to manage their health and prevent disease. PAM conceptualizes patient activation as a developmental process moving through four sequential levels: Level 1 (Passive) – the patient is disengaged, lacks understanding of their role, and is unwilling to take action; Level 2 (Aware) – the patient understands their role and importance of health behaviors but lacks confidence or is uncertain about ability; Level 3 (Taking Action) – the patient is taking steps to engage in self-management but may be inconsistent or uncertain how to maintain behavior; Level 4 (Maintaining Behavior) – the patient actively maintains self-management behaviors and prevents relapse. The PAM is widely used in primary care, chronic disease management, health insurance population health programs, and health services research to identify patients at risk of poor outcomes and to evaluate interventions targeting patient engagement.
