Convergent, discriminant, and known-groups validity of the Behavioural Assessment Screening Tool (BAST) in chronic traumatic brain injury.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background The Behavioural Assessment Screening Tool (BAST), which measures self-reported neurobehavioural symptoms experienced by adults with traumatic brain injury (TBI), was specifically developed as a self-reported measure for remote symptom reporting. Our aim was to assess the convergent, discriminant, and known-groups validity of the BAST among community-dwelling adults with TBI. Methods We assessed correlations and group differences with previously validated measures in two existing datasets (n =111, n =134). Other measures were the Patient Health Questionnaire-9 (depression), Generalized Anxiety Disorder-7 (anxiety), Positive and Negative Affect Schedule, Frontal Systems Behavior Scale (Executive Dysfunction, Apathy, Disinhibition), Modified Fatigue Impact Scale, Patient-Reported Outcomes Measurement Information System (Fatigue), Aggression Questionnaire (anger, hostility, physical and verbal aggression), and Alcohol Use Disorders Identification Test (alcohol misuse). Results BAST subscales had stronger correlations with measures of similar (|r |=0.602-0.828, P r |=0.364-0.589, P r |d =1.2-1.9) for known groups with moderate-severe depression, moderate-severe anxiety, fatigue, problematic disinhibited and frontal executive behaviours, and alcohol misuse. Results support the construct validity of the BAST subscales. Conclusion(s) The BAST demonstrated good convergent, discriminant, and known-groups validity, supporting its use for remote self-reported symptom reporting to improve chronic symptom monitoring in community-dwelling adults with TBI.
