Detecting depression in Chinese stroke patients: a pilot study comparing four screening instruments

Area of Science:

• Neuroscience
• Psychiatry
• Rehabilitation Medicine

Background:

• Post-stroke depression is a common complication affecting patient recovery and quality of life.
• Accurate screening for depression is crucial for timely intervention in stroke patients.
• Cultural specificity of screening tools is a significant consideration in diverse populations.

Purpose of the Study:

• To evaluate the suitability of different depression screening instruments for Chinese stroke patients.
• To compare the performance of the Visual Analogue Mood Scale (VAMS), Hospital Anxiety and Depression Scale (HADS), and Geriatric Depression Scale (GDS).

Main Methods:

• A sample of 60 Chinese first-ever stroke patients in a rehabilitation facility were assessed.
• Screening instruments included VAMS, HADS, and GDS; psychiatric diagnoses used SCID-DSM-III-R as a benchmark.
• Performance metrics included response rate, sensitivity, specificity, predictive values, and ROC curves.

Main Results:

• The VAMS demonstrated limited utility for detecting depression in this cohort.
• Both HADS and GDS showed satisfactory accuracy in identifying depression among Chinese stroke patients.
• Comparative analysis confirmed the efficacy of HADS and GDS over VAMS.

Conclusions:

• Depression screening tools are not universally applicable and exhibit cultural specificity.
• Established screening scales require validation in different cultural contexts before clinical use.
• HADS and GDS are recommended for screening depression in Chinese stroke patients, pending further validation.
