This study examined the relative influences of family functioning (gen
eral) and family members' sense of competence (specific) on the commun
ity adaptation of 180 seriously mentally ill adults. Stratified sampli
ng of families allowed for a mix of socioeconomic status and ethnic gr
oups. While both variables were significantly associated with the ill
family member's level of adaption, sense of competence was the more po
werful influence. Differences among ethnic and SES groups suggest that
this is particularly important for African American families and for
the lower-middle class.
