Psoriasis is a significantly impairs quality of life. Nail involvement is observed in approximately 50% of patients. Therefore, this study aimed to evaluate the Turkish validity of NPQ-10 and NAPPA, which are quality-of-life assessment tools specific to nail psoriasis. Patients with nail involvement who presented to the Dermatology outpatient clinic of Cerrahpaşa Medical Faculty were included in the study. The NPQ-10 and NAPPA questionnaires were translated into Turkish following international guidelines (forward-backward translation, expert review, pretesting). Demographic and clinical parameters (PASI, PGA, NAPSI, Nail-VAS) were recorded, and DLQI, NPQ-10, and NAPPA were administered to each participant. A total of 71 patients (42 male, 29 female) were evaluated. The mean age of participants was 42. Nail involvement most frequently affected both fingernails and toenails simultaneously (73.2%). PASI scores were significantly higher in men (p=0.031). DLQI and NPQ-10 scores were higher in males, while NAPPA-stigma scores were higher in females; however, these differences were not statistically significant. DLQI scores showed significant positive correlation with both NPQ-10 and NAPPA-QoL (r=0.453, r=0.477). Patients with toenail involvement had significantly higher DLQI, NPQ-10, and NAPPA scores. Nail bed involvement appeared to have a more pronounced psychosocial impact. Lower educational level was associated with worse quality-of-life scores (p<0.05).
