Latent class membership probabilities and conditional item-response probabilities of latent class membership

	Conditional item-response probabilities of adequate protection^a

	Inadequate Protection	Adequate External	Adequate Protection w/Low Adult Communication	Adequate Protection w/Risky Friends	Adequate Protection
Latent class membership probabilities	11%	10%	17%	9%	54%
Internal protective factors
Life satisfaction	0.29^b	0.49^c	0.62^d	0.81^d	0.93^d
Planful competence	0.53^c	0.55^c	0.77^d	0.88^d	0.86^d
Physical activity	0.56^c	0.53^c	0.71^d	0.82^d	0.82^d
Positive school orientation	0.19^b	0.39^b	0.83^d	0.65^d	0.94^d
External protective factors
Parents’ monitoring/limit-setting	0.43^c	0.62^d	0.63^d	0.67^d	0.89^d
Parent–child communication	0.16^b	1.00^d	0.31^b	0.71^d	0.95^d
Low friends’ ATOD use	0.42^c	0.61^d	0.86^d	0.25^b	0.90^d
Other adult communication	0.44^c	0.86^d	0.44^c	0.94^d	0.89^d

Item-response probabilities indicate a response of adequate protection (i.e., received a score of “2” for the indicator)

Low (<0.40) strength of the probability

Moderate (0.40–0.60) strength of the probability

High (>0.60) strength of the probability
