Musical Attention Control and Executive Function Training for Adults With MDD

This cognitive task measures response time, accuracy, commission errors, omission errors, and reaction time variability.

This cognitive task measures span length, correct recall, error rate, and reaction time.

This cognitive task measures the ability to shift attention between different stimuli, assessing the speed and accuracy with which the individual can shift their attention and switch between different rules.

This cognitive task measures the time to complete the task and errors made.

In Trail Making Test A, a longer completion time and higher number of errors can indicate difficulties with processing speed and attention.

In Trail Making Test B, a longer completion time and a higher number of errors on Trail Making Test B, compared to Trail Making Test A, can indicate difficulties with cognitive flexibility, mental shifting, and attention.

This cognitive task measures the time to complete the task and errors made. A longer completion time and a higher number of errors can indicate difficulty with selective attention and mental flexibility.

A 21-item self-report scale that quantifies suicidal ideation. The BSSI is a Likert-style questionnaire, where each item is rated on a scale from 0 to 3, with higher scores indicating a greater severity of suicidal thoughts and behaviours. The minimum possible score on the BSSI is 0, which would indicate the absence of suicidal ideation. The maximum possible score is 63, which would indicate a high level of severity of suicidal thoughts and behaviours.

A 10-item scale to assess the experience of positive and negative emotions/feelings. Each item is rated on a 5-point Likert scale, ranging from 1 (very slightly or not at all) to 5 (extremely).

The minimum possible score on the PNAS-SF for positive affect is 10, which would indicate the absence of positive affect. The maximum possible score is 50, which would indicate a high level of positive affect.

The minimum possible score on the PNAS-SF for negative affect is 10, which would indicate the absence of negative affect. The maximum possible score is 50, which would indicate a high level of negative affect.

A 16-item validated depression scale. Each item is rated on a 4-point Likert scale, ranging from 0 (not at all) to 3 (severe).

The minimum possible score on the QID-SR is 0, which would indicate the absence of depression. The maximum possible score is 48, which would indicate a high level of depression severity.

A validated 16-item scale to assess quality of life. Each item is rated on a 7-point Likert scale , ranging from 1 (terrible) to 7 (delighted).

The minimum possible score on the QOLS is 16, which would indicate poor quality of life. The maximum possible score is 112, which would indicate excellent quality of life.

Feasibility and Acceptability survey and interview created in-house with questions designed to collect quantitative and qualitative feedback from participants with respect to the feasibility and acceptability of the music-based cognitive training intervention.
