Reported severity of psychotic, depressive and anxiety symptoms in relation to bilingual language profile: An exploratory study and the validation of Basque versions of the PQ-B, DASS-42, PHQ-9 and GAD-7.

Background: Language plays a crucial role in health care and especially in mental health, since the use of the native language helps to make a good diagnosis as several studies have shown.

Aim: We studied the influence of language on the accurate detection of psychotic and affective symptoms, exploring differences in the severity of reported symptomatology in a bilingual Basque-Spanish population.

Methods: The study uses the Prodromal Questionnaire-Brief for the detection of psychosis and the Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale-7, and Depression, Anxiety and Stress Scale-42 for the assessment of stress, anxiety and depression.

Manic and depressive symptoms and insight in first episode psychosis.

Insight impairment is common early in the course of psychosis. Most studies have focused on the relationship between insight and depression, although manic symptoms are also frequent in psychoses. The main aim of this study was to examine the relationship between insight dimensions and manic and depressive symptoms in first-episode psychosis.
