Pediatric Sleep Questionnaire sensitivity and specificity for identifying obstructive sleep apnea (OSA) among adolescents identified as high risk on the Berlin Questionnaire A cut-off value of 0.33 was used for the PSQ total and subscores (sleepiness & snoring).

Item	Cutoff	Sensitivity	Specificity	PPV	NPV
PSQ Total	AHI≥1.0	82 (66–92)	71 (29–96)	94 (80–99)	42 (15–72)
PSQ Total	AHI≥5.0	86 (64–97)	38 (19–59)	55 (36–72)	75 (43–95)
PSQ Sleepiness	AHI≥1.0	63 (42–81)	100 (48–100)	100 (81–100)	33 (12–62)
PSQ Sleepiness	AHI≥5.0	54 (25–81)	47 (24–71)	41 (18–67)	60 (32–84)
PSQ Snoring	AHI≥1.0	59 (39–77)	43 (10–82)	81 (85–95)	20 (4–48)
PSQ Snoring	AHI≥5.0	59 (33–82)	42 (20–67)	48 (26–70)	53 (27–78)
PSQ Does your child snore <50% of the time?	AHI≥1.0	64 (45–80)	43 (10–82)	84 (64–96)	20 (4–48)
PSQ Does your child snore >50% of the time?	AHI≥5.0	68 (43–87)	43 (22–66)	52 (31–72)	60 (32–84)

AHI= obstructive apnea hypopnea index, PPV= Positive Predictive Value, NPV=Negative Predictive Value, PSQ=pediatric sleep questionnaire.
