Psychophysiological Response in Patients Undergoing Percutaneous Coronary Intervention: A Systematic Review and Walker–Avant Concept Analysis

Background: Psychological well-being is crucial for breast cancer survivors facing chronic illness and psychosocial challenges, yet psychological well-being remains inconsistently defined in the literature. Objective: To clarify the definitions, attributes, antecedents, consequences, and empirical indicators of psychological well-being using the Walker-Avant concept analysis. Methods: A systematic literature review was conducted using PubMed, ScienceDirect, Google Scholar, and ProQuest. Empirical and theoretical full-text studies addressing psychological well-being were selected following PRISMA guidelines. Seven articles were analyzed using the eight steps of the Walker-Avant method. Results: Key frameworks from Ryff, Ryan and Deci, WHO, Diener et al., Keyes, Zhou et al., and Grassi et al. indicate that psychological well-being is a motivational process characterized by self-acceptance, emotional regulation, adaptive coping, positive social relationships, meaning in life, autonomy, and adaptive capacity. Antecedents include illness perception, early distress, social support, and self-efficacy, while consequences involve positive adaptation, improved quality of life, and emotional stability. Conclusions: Psychological well-being is a multidimensional, dynamic construct essential to the adaptation of breast cancer survivors aged 10–25 years and provides a theoretical basis for developing evidence-based nursing interventions to improve mental health and quality of life.
