Table 1 -. Demographics and Self-report Pain Scores.

Female, male, and total sample demographics and self-report pain scores are described in Table 1. Self-report pain scores were given to participants on the Numeric Rating Scale (NRS), a standardized pain intensity assessment (mild: 1–3; moderate: 4–6; severe: 7–10) (Krebs et al., 2007) on a scale of 0 (no pain) to 10 (worst pain imaginable).

Demographics
	Males n=7	Females n=25	Total n=32
Age (years): mean (SD)	15.0 (1.3) Range: 14–17	13.6 (1.7) Range: 10–16	13.9 (1.7) Range: 10–17
Race	White, n = 6 Black, n = 1 Asian, n = 0	White, n = 22 Black, n = 2 Asian, n = 1	White, n = 28 Black, n = 3 Asian, n = 1
Self-report numeric pain score: scale 0 (no pain) to 10 (worst pain)
Presurgical: Mean (SD)	0.9 (1.2)* Range: 0 to 3	2.4 (2.5)* Range: 0 to 8	2.1 (2.4) Range: 0 to 8
4–6 months post-surgical: Mean (SD)	0.9 (1.6) Range 0 to 4	2.0 (2.1) Range: 0 to 7	1.7 (2.1) Range: 0 to 7
