Stress and depression scales in aphasia: relation between the aphasia depression rating scale, stroke aphasia depression questionnaire-10, and the perceived stress scale.

PMID 27348232WHAT IT FOUND
In 25 adults with aphasia, two caregiver-reported depression scales were strongly related to each other and to participants' self-reported stress.
The scales may help flag depressive symptoms, but this small study did not test diagnosis or treatment.
Key findings
01In the 25-participant sample, the SADQ-10 and ADRS showed a strong positive correlation (r = 0.708, p < 0.001).
02SADQ-10 scores correlated with perceived stress at r = 0.620, p = 0.003, and ADRS scores correlated with perceived stress at r = 0.492, p = 0.027.
03Ten participants met the threshold on both depression scales.

What it does not show
The study included 25 adults, so it is small and cannot establish how well the scales work in broader aphasia populations. It was a single-session assessment. It did not randomise treatment, follow patients over time, or test whether using the scales changes care. There was no verified gold-standard clinical depression diagnosis. The paper notes that depression diagnosis was not verified through medical records. Scale completion was incomplete: 22 PSS scores, 24 SADQ-10 scores, and 23 ADRS scores were obtained from 25 participants. The depression scales were completed by caregivers or individuals with at least weekly contact, so responses may reflect observer bias rather than the patient's own experience. The sample included 13 mild, 5 moderate, 4 severe, 1 very severe, and 2 beyond the WAB-R aphasia cut-off who continued to self-identify as living with aphasia.

The easy way to misread this
Do not read the strong correlations as proof that the ADRS or SADQ-10 diagnoses depression. The study found associations among scale scores in 25 adults with aphasia, and clinical depression diagnosis was not verified through medical records.
