Modelling longitudinal survey data often requires dealing with missing data. If a missing at random mechanism cannot be assumed, a missing not at random approach should be considered.

A latent growth mixture model with latent trajectory classes is considered, in combination with a latent class variable that summarizes the missing data patterns. Longitudinal survey data from the British Household Panel Survey on job satisfaction with total pay for the period 2002 to 2008 are used. The statistical modeling is conducted with the program Mplus.
