Population: All participants who completed one or more sessions of the computerized PASAT. Positive change reflects improved cognitive-affective functioning (distress tolerance) over time.

Estimated change in percentage of trial attempts on round 3 of the PASAT. A positive number reflects more trial attempts in the third round of PASAT.

Population: All participants who completed the digit backwards for both pre- and post-treatment cognitive-affective battery

Score on digit backwards. Fourteen strings of varying lengths (2 to 7 digits) are presented. A participant receives a point for each string they correctly repeat backwards. Range 0-14 points. Change score was calculated-positive values indicate improved working memory over time.

Population: All participants who completed the breath holding task for both pre- and post-treatment cognitive-affective battery

Negative emotionality-distress tolerance as measured by the difference between when the participant says they are uncomfortable and when they let go of holding their breath. Measured in seconds (this was natural log-transformed due to skewness for analyses). Positive change indicates improved distress tolerance over time.

PRIMARY outcome

Timeframe: from the week prior to training (pre) to the week after training (post)

Population: All participants who completed the delay discounting task for both pre- and post-treatment cognitive-affective battery

Incentive salience- delay discounting. Five-Trial Adjusting-Delay Discounting Task (Koffarnus \& Bickel, 2014) is a 5-item behavioral assessment used to estimate the extent to which individuals prefer smaller immediate rewards over larger delayed rewards. A discount rate (ln (k)) is calculated for each time the measure is used. Discount rates for the 5- trial delay task were calculated by taking the inverse of the obtained Effective Delay 50 value, which is equivalent to the value of k, when fitted to this singular point. Ln(k) is the natural log of the discount rate. A change score was calculated. Negative change indicates improved decision-making
