Measure
Cognitive Training Plus Treatment as Usual
Participants in this arm received daily computerized cognitive training sessions during partial hospitalization, in addition to treatment as usual. Cognitive training sessions alternated between response inhibition training and working memory training. Cognitive Control Training: Cognitive Control Training involves daily practice with one of two computerized interventions. The first intervention is an adaptive Go/No-Go task to provide practice in the domain of response inhibition. Participants press a key as fast as possible in response to stimuli (letters of the alphabet), but must inhibit responses to a specific letter. The second intervention is an adaptive Paced Auditory Serial Addition Task (PASAT), designed to practice working memory. Participants are presented with single numbers presented aurally, and must add each number they hear to the previous number and click the correct sum on the screen.
Treatment as Usual (TAU)
Participants in the Treatment As Usual group will receive usual treatment in the partial hospitalization program.

Baseline Characteristics

Two participants in each arm did not complete the stop-signal task. In the cognitive training arm, 1 participant reported an exclusion criterion and discountined participation prior to completion of this task. 1 additional participant did not attend their session in which this task was to be completed. In the TAU arm, 1 participant dropped out of the study prior to completion of this measure, and 1 additional participant was not able to complete the task because of time constraints.

PRIMARY outcome

Timeframe: Admission and at study completion (day of discharge), an average of two weeks. Scores reported below are at day of discharge.

Population: Note: two participants in the Treatment as Usual condition did not answer all questions for the Negative Urgency scale at discharge, so an average score was not computed, resulting in 17 participants with complete data.

This scale assesses tendencies towards impulsive action in response to negative emotion. The scale ranges from 1-4, with higher scores indicating more problems with this type of impulsivity.

SECONDARY outcome

Timeframe: Baseline and at study completion (discharge), an average of two weeks. Scores reported below are at discharge.

Population: 4 participants in the Cognitive Training plus Treatment as Usual group did not complete the Stop Signal task at discharge, for various reasons including: no-show to data collection session (1), equipment problem (1), clinical issues interfering with data collection (1), and time constraints (1); this resulted in a total of 11 participants with data for this task in this arm.

The SSRT (measured in ms) is the primary behavioral outcome measure of the Stop-Signal Response Inhibition task. It is an estimate of the average amount of time required to stop an action on this task.

SECONDARY outcome

Timeframe: Baseline and at study completion (discharge), an average of two weeks. Baseline data and discharge data are shown separately below.

We evaluated the feasibility of using EEG to assess event-related potentials during the Stop-Signal task, in an acute partial hospital setting. This involves testing the percentage of participants who are able to complete and provide ERP data for the stop-signal task.

Completion Rates
15 Participants

SECONDARY outcome

Timeframe: At study completion, an average of two weeks.

Population: One participant did not fill out this measure due to clinical issues interfering with data collection, resulting in 14 participants with available data. One additional participant filled out the measure but declined to fill out the item assessing perceived helpfulness of the PASAT, resulting in 13 participants available for anaylsis for this specific item.

This is a study-specific measure developed by the investigators to capture self-reported perceived helpfulness of the intervention. It consists of two separate questions that assess "how helpful" the Go/NoGo task and PASAT tasks were perceived to be. Each question is rated on a 1 ("completely disagree") to 7 ("completely agree") scale, with higher scores indicating better outcomes (i.e., greater perceived helpfulness of the task). Scores shown below are averages for each of these two items.

Timeframe: Admission and at study completion (day of discharge), an average of two weeks. Scores reported below are at day of discharge.

Population: Note: two participants in the Cognitive Training plus Treatment as Usual arm, and 3 participants in the Treatment as Usual arm, did not answer all questions for the Distress Intolerance Index at discharge, so an average score was not computed, resulting in smaller sample sizes for these analyses.

This scale assesses self-reported difficulties tolerating distress. Total scores range from 0 to 40, with higher scores indicating greater difficulties tolerating distress.
