Expressed emotion is a robust and reliable predictor of psychiatric re
lapse across a range of psychopathological conditions and diagnoses. T
heoretical speculation about the expressed emotion construct has sugge
sted that high levels of criticism in relatives might be linked to att
ributions and beliefs about the patient's ability to control his or he
r symptoms or problem behaviors. Although there is some empirical supp
ort for this notion, no study to date has examined relatives' beliefs
about their own abilities to control problem situations. This study co
mpared high- and low-critical relatives of patients with schizophrenia
on a measure of locus of control. Consistent with prediction, the loc
us of control scores of high-critical relatives were indicative of a m
ore internal locus of control, whereas those of the low-critical relat
ives were indicative of a more external locus of control.
