Table 3. Premorbid maladjustment ratings and univariate prediction of conversion to psychosis versus nonconversion.

Conversion Status	Developmental Period
	Childhood		Early Adolescence		Late Adolescence
	Mean (SE, n)	HR (95% CI)	Mean (SE, n)	HR (95% CI)	Mean (SE, n)	HR (95% CI)
Social maladjustment
Psychosis conversion	1.70 (0.2, 72)	1.16 (0.92–1.44)	2.20 (0.2, 74)	1.30* (1.06–1.61)	2.30 (0.2, 57)	1.23† (0.96–1.58)
Nonconversion	1.46 (0.1, 173)		1.72 (0.1, 177)		1.82 (0.1, 99)
Academic maladjustment
Psychosis conversion	1.48 (0.1, 72)	0.97 (0.77–1.21)	2.34 (0.2, 73)	0.91 (0.72–1.13)	2.58 (0.2, 56)	1.06 (0.83–1.36)
Nonconversion	1.42 (0.1, 171)		2.41 (0.1, 177)		2.21 (0.2, 99)
Total maladjustment
Psychosis conversion	1.59 (1.2, 72)	1.06 (0.85–1.34)	2.25 (1.1, 74)	1.12 (0.90–1.40)	2.39 (1.3, 57)	1.14 (0.88–1.49)
Nonconversion	1.44 (1.0, 175)		1.99 (1.6, 180)		1.97 (1.2, 102)

Note: Mean values reflect unadjusted Premorbid Adjustment Scale ratings, with higher scores representing greater pathology. Cox regression analyses were performed using standardized Premorbid Adjustment Scale ratings. The covariate for academic and total maladjustment is baseline year. HR, hazard ratio; CI, confidence interval.
