Recent work suggests that some people who have severe and persistent mental
illnesses can be transferred to less intensive services without suffering
ill effects. However, the factors that affect the success of such transitio
ns remain unknown. This longitudinal study examines consumer characteristic
s and types of intensive case management services that predict decompensati
on. We examined the trajectories of 86 individuals in an intensive case man
agement program after they attained the highest level of functioning, ident
ifying three patterns: stability, immediate decline followed by improvement
, and gradual decline. Number of hospitalizations prior to program entry, b
eing judged suicidal at program entry, and greater use of psychiatric servi
ces during program participation consistently predicted decompensation. Sub
stance abuse and psychiatric symptomatology at program entry also predicted
decompensation, but did so less consistently. Predictors of differences in
specific patterns of decompensation are explored.
