Path diagrams for the LCGA applied to the various measures of the subjective phenomenon. S(t) raw score, stS(t): standardised score, θ (t)sim : simulated latent variable, θest: latent variable score, θ(t): latent variable score estimated by the Rasch model applied to the items (I (t)j ) at each time t. Factor loadings are set at 1 unless otherwise stated. In: intercept of the latent trajectory, Sl: slope of the latent trajectory, C: the latent class, LCGA: Latent Class Growth Analysis
