In the field of alcoholism treatment, as in mental health treatment mo
re generally, no one treatment model is equally effective for all pati
ents and problem types. A review of the literature in both alcohol tre
atment and in psychotherapy research suggests some relationships in co
mmon between treatment efficacy and patient coping style, drinking pat
terns, and family dynamics. This literature suggests that ''internaliz
ing'' alcoholics, whose drinking tends to be steady and to be function
ally interwoven with family dynamics, will benefit more from family-sy
stems oriented treatments than from symptom- or individual focused tre
atments. Conversely, ''externalizing'' alcoholics may derive more bene
fit from symptom-focused cognitive and behavioral treatments than from
family systems treatment. We describe an ongoing research project des
igned to test these hypotheses and the development of treatment manual
s that may increase differential treatment efficacy.
