With longitudinal data, the number of levels in Mplus is one less than the number of levels in conventional multilevel modeling programs. The multivariate approach allows flexible modeling of relationships between the outcomes such as correlated residuals over time and regressions among the outcomes ...
Data from the 2013 wave were excluded due to deviations in categorisation. This measure is described henceforth as “self-declared mental illness”. Additionally, continuous symptom scales were used. Symptoms were measured at several data waves, using either the Center for Epidemiologic Studies ...
