Can we do Latent Growth Curve Analysis with two wave data?
There are two groups (experimental and control groups), each with n=100. Subjects are randomly assigned to experimental and control group. Pre-test was administered to each group, while posttest (same questionnaire used in the pretest) was administered after the intervention after several months. The test scores are latent variables. Can we do the following analyses using SMARTPLS?: (1) relationship between pretest score (intercept) and rate of change (slope) in scores(from pretest to posttest); (2) effect of the intervention program (experimental versus control) on the slope; and (3) effect of some demographic characteristics (e.g. gender, civil status) on the relationship between intervention program and slope.
