Introduction: Arthritis is a common condition that significantly affects both physical and mental health, thereby impacting the overall quality of life. However, there is limited research exploring the differences in the impacts of arthritis on mental health and quality of life between adults and the elderly.

Objective: This study aimed to explore the mental health implications of arthritis and how it impacts the quality of life in adults and elderly individuals.

Material and Methods: A mixed-methods approach was used, combining quantitative measures (Arthritis Impact Measurement Scales (AIMS2), Patient Health Questionnaire (PHQ-9), and Short Form Health Survey (SF-36) with qualitative interviews.

Results: Both adults and elderly individuals reported significant impacts on physical, social, and emotional aspects related to arthritis, with the elderly reporting higher physical impact scores and lower social impact scores. Depressive symptoms were present in both groups, with significantly higher scores among the elderly. Quality of life was also lower among the elderly.
