Validation of the Depression and Family Functioning Scale (Dffs)
Patient-reported outcomes (PROs) are necessary to assess disease impacts from the patient’s perspective. In line with the Food and Drug Administration’s (FDA’s) guidance on PROs, the Depression and Family Functioning Scale (DFFS) was developed to assess the impact of major depressive disorder (MDD) on family functioning. Psychometric analyses were conducted to establish the reliability, validity, and responsiveness of the DFFS according to the FDA PRO guidance.
