Supports HADS anxiety subscale screening in schizophrenia; leaves depression subscale validity open for further validation.
Cross-Sectional (n=100)
Can the Hospital Anxiety and Depression Scale be used to screen for anxiety and depression in patients with schizophrenia?
The HADS anxiety subscale appears valid for assessing anxiety in schizophrenia, but caution is advised when using the depression subscale.
Allan et al. (2009) conducted a cross-sectional in Schizophrenia (n=100). Hospital Anxiety and Depression Scale (HADS) was evaluated on Psychometric properties (factor structure) of the HADS. Factor analysis of the HADS in patients with schizophrenia supported the clinical use of the anxiety subscale but found the depression subscale may not be a unidimensional measure.
