Fig. 1From: Parent and peer relationships as longitudinal predictors of adolescent non-suicidal self-injury onsetPath diagram of proportional and nonproportional discrete-time survival models. Top figure shows a proportional model, in which the time-lagged associations between predictors at age t and NSSI onset at age t + 1 are set to equality across all assessment waves. Bottom figure shows a non-proportional model, in which each time-lagged association is estimated independently, and can vary over timeBack to article page
