Cognitive Training Video Game to Target Subclinical Depressive Symptoms in Youth

The CDI was a self-report, 27 item scale used to measure depressive symptoms. Total scores on the CDI ranged from 0 (no depressive symptoms) to 54 (extremely severe depressive symptoms). Higher scores indicated worse depressive symptoms. CDI scores were collected from participants at three timepoints: 1) baseline, 2) approximately 5 weeks after baseline, and 3) up to 4 months after baseline. Results reflect CDI scores collected at the first and second timepoints.

The CDRS-R is a clinician-administered tool used to assess the severity of depression in children and adolescents based on a 17-item scale of depressive symptoms. Total raw scores on this scale range from 17-113, with 17 indicating no or minimal depressive symptoms and 113 indicating extremely severe symptoms of depression. CDRS-R scores were collected from participants at three timepoints: 1) baseline, 2) approximately 5 weeks after baseline, and 3) up to 4 months after baseline. Results reflect CDRS-R scores collected at the first and second timepoints.

The Stroop task assesses cognitive control and emotion regulation over emotional information processing by measuring how quickly individuals name the ink color of words that are emotionally-charged or neutral. For this measure, lower scores indicated better performance, i.e., better cognitive control and emotion regulation. Results reflect the average reaction time across all trials of the Stroop task that participants completed.

The Stroop task assesses cognitive control and emotion regulation over emotional information processing by measuring how quickly individuals name the ink color of words that are emotionally-charged or neutral. For this measure, lower scores indicated better performance, i.e., better cognitive control and emotion regulation. Results reflect the difference in the reaction time between incongruent trials and congruent trials on the Stroop task.

The Flanker task is a psychological experiment that assesses a person's ability to focus on a target stimulus while ignoring distracting stimuli. For this measure, higher scores indicate better performance. Results reflect the average reaction time across all trials of the Flanker task that participants completed at this timepoint.

Higher scores indicated worse depressive symptoms. CDI scores were collected from participants at three timepoints: 1) baseline, 2) approximately 5 weeks after baseline, and 3) up to 4 months after baseline. Results reflect CDI scores collected at the third timepoint.

Outcome measures that indicate how much the video game was played and acceptability of the game as indicated by self-report ratings. Includes:

gameplay metrics from the video game (total amount of missions completed across the 4-weeks of the intervention), Endeavor Satisfaction Survey Scores (Scale 1-5 (3 is neutral) on each item; parent and child report), and depressive symptoms at baseline (Children's Depression Inventory).
