Psychometric properties of the Chinese-version Behavioral Inhibition System/Behavioral Activation System Scales among stroke survivors with depressive symptoms.

PMID 39990995WHAT IT FOUND
The Chinese BIS/BAS scales seem usable for stroke survivors with depressive symptoms.
Ten participants found the items clear, scores were stable when retested, and people with probable depression showed lower activation and higher inhibition.
Key findings
01Ten stroke survivors found the instructions, items and response options clear and understandable.
02Stroke survivors with probable depression had lower behavioural activation scores and higher behavioural inhibition scores than those without probable depression.
03The scale had acceptable internal consistency, and one-week test-retest reliability values were reported for each subscale.

What it does not show
Participants had to speak Mandarin and could not have aphasia, cognitive impairment, diagnosed mental disorders or treatment, visual or hearing problems affecting participation, or other conditions likely to cause depression, so the results may not apply to many stroke survivors. The study used convenience sampling in four hospitals in Jiangsu, China, and only tested the Chinese version. There was no gold standard or validated comparator for behavioural activation in stroke survivors, so criterion validity was not examined. The study was cross-sectional and did not test whether the scale changes with treatment, improves depression management, or predicts outcomes over time. The BIS/BAS scales are normally treated as a trait measure without a time frame, although the authors added time frames for this study.
Declared interests
The authors declared no conflict of interest.
The easy way to misread this
Do not conclude that the BIS/BAS scales are ready for all stroke survivors or that using them improves depression care. The study tested a Chinese version in stroke survivors who could communicate and had no cognitive impairment, and it did not test an intervention.
