Fig. 1 — Conceptual representation of conditional discontinuous latent growth curve model.

Y1_T1-T5 indicates perceived stressfulness from T1 to T5. B_0,Y1 = Intercept; B_1,Y1 = Slope 1 [early April 2020 to early July 2020; parameterized as: −3, −2, 0, 0, 0]; B_2,Y1 = Slope 2 [early July 2020 to early September 2020; parameterized as: 0, 0, 0, 1, 2]. Common letters (i.e., “a,” “b”) denote parameters fixed to equality. Dashed lines indicate parameters fixed to 1.0. X₁…X_i represents exogenous predictors of intercept and slope terms.
