Cognitive Training Video Game to Target Subclinical Depressive Symptoms in Youth

Change in Depressive Symptoms as Measured by Children's Depression Inventory (CDI)

Time Frame: Baseline and approximately 5 weeks after

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.

Change in Depressive Symptoms as Measured by Children's Depression Rating Scale - Revised (CDRS-R)

Time Frame: Baseline and approximately 5 weeks after

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.

Change in Cognitive Control Capacity - Overall Reaction Time (RT) Stroop

Time Frame: Baseline and approximately 5 weeks after

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.

Change in Cognitive Control Capacity - Conflict RT Stroop

Time Frame: Baseline and approximately 5 weeks after

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.

Change in Cognitive Control Capacity - Overall RT Flanker

Time Frame: Baseline and approximately 5 weeks after

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.

Change in Cognitive Control Capacity - Conflict RT Flanker

Time Frame: Baseline and approximately 5 weeks after

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 difference in the reaction time between incongruent trials and congruent trials of the Flanker task.
