Table 3.

Item Response Probabilities Constrained Equal Across Time and Latent Transition Probabilities Conditioned on Baseline Latent Status for Three-Class Latent Status Conditional Model.

	Response probabilities by latent status at baseline
Sexual risk item	Abstainers	Multipartner—Safe	Multipartner—Exposed
Vaginal sex in past 12 months	0.0	1.00	1.00
Sex without condom in past 12 months	0.0	0.0	.65
Number of sexual partners in past 12 months	0.0	.58	.50
Pregnant/impregnated	0.0	0.05	.36
	Transition probabilities
	Follow-up membership
Baseline membership	Abstainers	Multipartner—Safe	Multipartner—Exposed
Abstainers	0.601	0.359	0.041
Multipartner—Safe	0.618	0.343	0.039
Multipartner—Exposed	0.516	0.459	0.025

Note. n = 573; Response probabilities represent the likelihood status members endorsed each sexual risk at baseline, while transition probabilities reflect the chance of follow-up status membership given baseline status. The main diagonal signifies stability over time, while off-diagonals denote transition in statuses.
