Jb. Persons et al., RELATIONSHIPS BETWEEN SYMPTOMS OF DEPRESSION AND ANXIETY AND DYSFUNCTIONAL BELIEFS ABOUT ACHIEVEMENT AND ATTACHMENT, Journal of abnormal psychology, 102(4), 1993, pp. 518-524
Psychiatric outpatients (N = 293) provided data to test the symptom sp
ecificity and final common pathway hypotheses about symptoms of depres
sion and anxiety. The symptom specificity hypothesis predicts that the
symptoms reported by a depressed or anxious patient depend on the dys
functional beliefs he or she endorses. In contrast, the final common p
athway hypothesis predicts that symptoms are unrelated to the types of
beliefs the patient endorses. These hypotheses were tested in the con
text of theories that emphasize the importance of dysfunctional belief
s about achievement and attachment. Only limited support for the sympt
om specificity hypothesis was obtained; support was strongest for the
link between attachment beliefs and anxiety symptoms. Relationships be
tween symptoms and dysfunctional beliefs did not depend on psychiatric
diagnosis.
