Results Overview

This self-report measure of depression severity is derived from a standardized questionnaire known for its good psychometric properties, including construct validity and test-retest reliability, in individuals without aphasia. Scale range: 0-120. Higher values represent higher degree of depression.

SECONDARY outcome

Timeframe: Immediately after 4 weeks of treatment (used only as an external criterion to explore the psychometric adequacy of the self-report co-primary outcome, the BDI)

Population: Post-Stroke Depression and Subacute Aphasia

This self-report questionnaire was conceived to quantify a person's confidence to overcome obstacles encountered when completing a difficult task. Results are expressed on a Likert scale ranging from 0 (very low self-efficacy) to 3 (very high self-efficacy). Results are expressed as sum scores ranging from 0 (very low self-efficacy) to 30 (very high self-efficacy). Reduced self-efficacy is discussed as one risk factor for depression. This instrument was used only for cross-sectional assessment, not for longitudinal assessment, to serve as an external criterion to explore the psychometric adequacy of the self-report co-primary outcome, the BDI.

OTHER_PRE_SPECIFIED outcome

Timeframe: Change from 1 day before start of treatment until immediately after 4 weeks of treatment.

Population: Post-Stroke Depression and Subacute Aphasia

This standardized aphasia test battery was found to be sensitive to treatment-induced short-term progress in language performance. To address the potential relationship between changes in cognitive-affective distress and verbal expression skills, we will use the combined AAT subscales "Repetition" and "Naming" as a covariate in exploratory evaluations. The AAT subscales "Repetition" and "Naming" as well as the resulting combined average score are based on a T-score distribution (M = 50; SD = 10). Higher T-scores represent better verbal expression skills. The results below indicate change over time.
