This study investigated aspects of adjustment to the therapeutic community
milieu in a group of personality disorder patients. Eighty-one patients con
secutively admitted to the Cassel Hospital for medium/long-term residential
treatment between April 1994 and October 1997 comprised the sample. The ad
justment to the milieu was rated on the Hospital Adjustment Scale, while ou
tcome was evaluated at G-monthly intervals using a battery of self-rated an
d rater-based instruments. The aims of the study were: (a) to identify demo
graphic and pre-admission clinical variables that would predict adjustment
to the therapeutic regime; (b) to study the relationship between hospital a
djustment and external social adjustment; and (c) to investigate the hypoth
esis chat hospital adjustment and internally and externally directed aggres
sion do not predict clinical outcome. The results showed that pre-admission
level of global functioning and a previous history of substance misuse are
the most significant predictors of hospital adjustment. No significant ass
ociation between hospital adjustment and external social adjustment was fou
nd. Neither hospital adjustment nor level of aggressiveness predicted outco
me at 12 months. The implications of these results for therapeutic communit
y treatment of personality disorder are discussed.
