Trial Outcomes & Findings for The Impact of the Attention Training Technique on Attention Control and High Worry (NCT NCT03216382)
NCT ID: NCT03216382
Last Updated: 2021-07-02
Results Overview
Behavioural measure of attention control over worry. Number of negative thought intrusions reported during the post-worry breathing focus period (i.e. a period of focused breathing after a period of worry). Scores range from 0-12. A greater number means more negative thought intrusions.
Recruitment status
COMPLETED
Study phase
NA
Target enrollment
95 participants
Primary outcome timeframe
Administered three times over the course of two weeks. Changes will be examined from Visit 1 (Baseline) to Visit 2 (Preintervention, 1 week following Baseline) and Visit 2 to Visit 3 (1 week following preintervention).

Attention Training Technique
Participants in this arm will listen to the Attention Training Technique. Participants will listen to the recording once in the lab, followed by a week of once/day listening at home for a week. For a week before the intervention, and for the week during the intervention, participants will respond to questions every evening, about their worry and attention that day.
Attention Training Technique: The ATT is a 12-minute audio recording that includes sounds and a voice guiding attention to the sounds. The sounds play continuously during the training task.
|
Control Condition
Participants in this arm will listen to the control condition recording. Participants will listen to the recording once in the lab, followed by a week of once/day listening at home for a week. For a week before the intervention, and for the week during the intervention, participants will respond to questions every evening, about their worry and attention that day.
Control Condition: In the control condition, participants listen to an audio recording with the same sounds as the ATT recording, and a voice that delivers placebo instructions.

PRIMARY outcome
Timeframe: Completed every evening for two weeks. The first week will take place before beginning the ATT/ control intervention. The second week will take place during the intervention period.A daily self-report measure of the frequency, duration, intensity and uncontrollability of worry. Only uncontrollability of worry was used (see Data Analysis Plan for rationale). Scores range from 0-6. Higher scores represent greater uncontrollability of worry.

For a week before the intervention, and for the week during the intervention, participants will respond to questions every evening, about their worry and attention that day.
Control Condition: In the control condition, participants listen to an audio recording with the same sounds as the ATT recording, and a voice that delivers placebo instructions.

SECONDARY outcome
Timeframe: Administered three times over the course of two weeks. Changes will be examined from Visit 1 (Baseline) to Visit 2 (Preintervention, 1 week following Baseline) and Visit 2 to Visit 3 (1 week following preintervention).Population: Participants were only included on this analyses if they had data for all time points. 17 participants were not included (10 from ATT, 7 from control). A substantial amount of data was lost due to a technical issue with the computer.
Behavioural measure of attentional bias to threat related words, measured in reaction time. A larger positive number indicates a greater bias to threat information while a negative number indicates the participant was faster to respond to neutral information.

Attention Training Technique
n=24 Participants
Participants in this arm will listen to the Attention Training Technique. Participants will listen to the recording once in the lab, followed by a week of once/day listening at home for a week. For a week before the intervention, and for the week during the intervention, participants will respond to questions every evening, about their worry and attention that day.
Attention Training Technique: The ATT is a 12-minute audio recording that includes sounds and a voice guiding attention to the sounds. The sounds play continuously during the training task.
