Trial Outcomes & Findings for Sex Differences, Cognitive Training & Emotion Processing (NCT NCT03137654)

NCT ID: NCT03137654

Last Updated: 2025-05-31

Results Overview

An interference task involving target words presented over non-target visual stimuli. The primary dependent measure is change in reaction time on trials with incongruent stimuli (e.g., a negative word presented over a "happy" face) from baseline to post-training assessment. Change scores are calculated by subtracting reaction time at post-training assessment from reaction time at baseline, thus positive values indicate improvements in processing speed from pre- to post-training (e.g., 500ms \[baseline score\] - 300ms \[post-training score\] = 200ms \[positive change score\]).

Population: Data from this task were corrupted, precluding any analysis

A reasoning and set-shifting task. Participants must determine novel rule sets for stimuli matching through trial and error. Ss must match each 'Test Card' with a 'Key Card'. Criteria for a successful match shift throughout the testing session and may include color, shape, and number of symbols. The primary dependent measure is the change in response accuracy from baseline to post-training assessment.

A working memory task involving numbers presented visually. Ss are presented with a list of digits, one at a time, followed by a probe digit. They must determine if the probe digit was in the original set of digits and recall the digits. The primary dependent measure is the change in response accuracy (proportion of correct responses) from baseline to post-training assessment. Positive values indicate greater proportions of correct responses at post-test, relative to baseline.

Summarizes responses to 14 different topics that may cause disagreements in the participants' family. Response to each topic is binarized (Yes = 1; No = 0). Single summary score is generated by summing across all topics. The maximum score is 14; the minimum score is 0. Higher values represent a worse outcome.

Indexes alcohol craving frequencies. Questions include: 1. Over the past week, how often did you have a strong urge to drink? 2. Over the past week, how often did you picture alcohol or drinking? 3. Over the past week, how often did you imagine what it would taste like? 4. Over the past week, how often did you imagine how your body would feel if you had a drink? Higher scores reflect greater craving. 5. Over the past week, how often were these thoughts intrusive? Participants respond on a scale from 1-10 for each question. Responses are summed. Thus, scores range from 5-50.
