There is a disagreement about the impact of personality disorder (PD) on treatment outcome for patients with major depressive disorder (MDD). 100 out-patients with MDD were randomized to 16 sessions of behavioural activation (BA) (n = 50) or antidepressant medication (ADM) (n = 50) in Iran. Main outcome was depression severity, measured with the Beck(More)

METHODS Participants with a diagnosis of cMDD (n=18) and age, gender and education level matched participants without a diagnosis of depression (n=18) underwent a(More)
OBJECTIVES Mental imagery abnormalities occur across psychopathologies and are hypothesized to drive emotional difficulties in bipolar disorder (BD). A comprehensive assessment of mental imagery in BD is lacking. We aimed to test whether (i) mental imagery abnormalities (abnormalities in cognitive stages and subjective domains) occur in BD relative to(More)
