Family-based predictors of relapse were examined in. 100 alcoholics wh
o participated in a 12-week treatment program with 6-month and 18-mont
h followups. ''Expressed Emotion'' (EE), or attitudes of relatives tow
ard the alcoholic as measured by the Camberwell Family Interview, scal
es measuring rejection of the alcoholic by relatives, and self-reports
of partner interaction were evaluated as possible predictors of absti
nence. During therapy, partnership interactions showed a transient det
erioration with increased temporary friction. Based on conservative cr
iteria, the abstinence rate was 40% at 6-month follow-up and 30% at 18
-month followup. An association with the relapse at followup could be
obtained for the Patient Rejection Scale (PRS) and, using empirically
derived classification rules, for the main three variables of the Camb
erwell Family Interview (CFI) conducted on admission: ''Critical Comme
nts,'' ''Emotional Overinvolvement,'' and ''Warmth.'' A low number of
Critical Comments and a high score in Warmth were associated with a lo
wer risk of relapse; however, contrary to expectations, Emotional Over
involvement of the significant other was associated with more abstinen
ce. In addition, the number of Critical Comments made by relatives abo
ut the alcoholic, a major component of high EE as measured by the CFI;
had a statistically significant impact on the ''survival function'' o
f abstinence, and thus contributed to the prediction of the course of
alcoholism in the expected direction.
