Trial Outcomes & Findings for Improving Therapeutic Learning in Depression: Proof of Concept (NCT NCT02376257)

NCT ID: NCT02376257

Last Updated: 2018-09-19

Results Overview

A modified Cognitive Therapy Awareness Scale (CTAS) was used to assess delayed memory for cognitive therapy content from the computerized CBT. Higher scores indicate better memory for CBT skills. Scores range from 0 to 40.

Population: Data is missing for two participants.

The Hopkins Verbal Learning Test (HVLT) consists of a 12-item word list, composed of four words from each of the three semantic categories. The patient's free recall of the list is recorded. The same procedure is repeated for two more trials. The total recall score for the third trial was used as the recorded score and ranged from a minimum of zero to a maximum of 12 correct answers.
