Physical development was assessed with a sex-specific 5-item self-report measure (Petersen et al., 1988). Youth selected 1 of 5 sex-specific statements ranging from “has not begun yet” to “seems complete” indicating current level of pubertal development. Multiple domains of secondary sex characteristic development (e.g., menstruation, facial hair growth, etc.) were sampled to most closely ascertain Tanner staging, characterized as pre-, early, mid-, late, or postpubertal. Pubertal staging is relevant here, as any FH-related differences could account for developmental discrepancies in brain activation.
