Abstract
Rheumatoid arthritis (RA) patients face significant psychological challenges alongside physical symptoms, necessitating a comprehensive understanding of how psychological vulnerability and adaptation patterns evolve throughout the disease course. This review examined 95 studies (2000-2025) from PubMed, Web of Science, and CNKI databases including longitudinal cohorts, randomized controlled trials, and mixed-methods research, to characterize the complex interplay between biological, psychological, and social factors affecting RA patients' mental health. Findings revealed three distinct vulnerability trajectories (45% persistently low, 30% fluctuating improvement, 25% persistently high) and four adaptation stages, with critical intervention periods occurring 3-6 months post-diagnosis and during disease flares. Multiple factors significantly influence psychological outcomes, including gender (females showing 1.8-fold increased risk), age (younger patients experiencing 42% higher vulnerability), pain intensity, inflammatory markers, and neuroendocrine dysregulation (48% showing cortisol rhythm disruption). Early psychological intervention (within 3 months of diagnosis) demonstrated robust benefits, reducing depression incidence by 42% with effects persisting 24-36 months, while different modalities showed complementary advantages: Cognitive behavioral therapy for depression (Cohen's d = 0.68), mindfulness for pain acceptance (38% improvement), and peer support for meaning reconstruction (25.6% increase). These findings underscore the importance of integrating routine psychological assessment into standard RA care, developing stage-appropriate interventions, and advancing research toward personalized biopsychosocial approaches that address the dynamic psychological dimensions of the disease.
