ABSTRACT
BACKGROUND:
Forehead lines (FL) are one of the main signs of aging. Traditional tools to measure FL have limited ability to evaluate the multidimensional impact of these lines on appearance, confidence, and psychological and social relationships.OBJECTIVES:
We developed and validated the Facial Line Distress Scale-Forehead Lines (FINE-FL) to evaluate the severity and psychosocial distress associated with FL.METHODS:
We conducted a cross-sectional survey for FINE-FL psychometric validation at a tertiary hospital and 2 local clinics in Korea. First, a preliminary item pool for the FINE-FL was developed through a qualitative interview based on literature reviews and expert consultations. Second, cognitive interviews and a pilot test were conducted to evaluate comprehension, ease of response, acceptability of terminology, phrasing, and response options. FINE-FL consisted of 26 items. In this study, exploratory factor analysis was conducted to identify the underlying factor structure of the FINE-FL, and internal consistency and test-retest reliability were also examined.RESULTS:
We found 21 items in 4 domains. The model fit was good. Coefficient αs ranged from 0.89 to 0.95 for subdomains and 0.96 for the total. The FINE-FL was moderately correlated with the appearance appraisal score. On the test-retest, the range of the intraclass correlation coefficient was 0.65 to 0.79.CONCLUSIONS:
FINE-FL is a reliable, valid, and comprehensive patient-reported outcome measure for assessing FL severity and distress. This will be helpful in determining a patient's eligibility for inclusion in a study and measuring primary or secondary effectiveness endpoints for forehead line treatment.
