Effects of Noise Cancelling Headphones on Neurocognitive and Academic Outcomes in ADHD

Not Applicable

Completed

• Conditions: ADHD
• Interventions: Other: Use of Noise Cancelling Headphones

• Registration Number: NCT03216512
• Lead Sponsor: Duke University

Brief Summary

The purpose of this study is to evaluate performance on the Attention Deficit Hyperactivity Disorder ( ADHD) Battery of the Cambridge Automated Neuropsychological Test Battery (CANTAB), including spatial working memory, inhibitory control, and attention while using either a noise cancelling headphone or sham headphone control in the presence of standardized auditory distractors in children and adolescents with ADHD.

Detailed Description

This will be a proof-of-concept, randomized, within-subject cross-over design with the administration of noise cancelling headphones or sham headphones on two separate study days. Following screening and a baseline assessment session with no headphones, participants will be assigned to complete each experimental session. During each session, they will undergo the CANTAB and Academic tasks. The order of sessions will be randomized and balanced across participants to be either noise-cancelling headphones first followed by sham headphones; or sham headphones first followed by noise-cancelling headphones. Eligible participants currently taking stimulant medications for ADHD will be asked to stop taking their medication on the day of the baseline visit and during the 2 experimental sessions.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 36

Inclusion Criteria

• Age 6 to 17 at the time of parental informed consent.
• Male or female.
• Confirmed ADHD diagnosis at screening visit established via MINI-KID (version 7.0.2) administered by a trained clinician.
• Screening ADHD-RS-IV score ≥24.

Exclusion Criteria

• Current controlled (requiring a restricted medication) or uncontrolled, comorbid psychiatric diagnosis, based on MINI-KID and subsequent clinical interviewing, with significant symptoms including but not limited to post-traumatic stress disorder, psychosis, bipolar illness, pervasive developmental disorder, severe obsessive-compulsive disorder, severe depressive or anxiety disorder, conduct disorder, or other symptomatic manifestations that in the opinion of the Investigator may confound study data/assessments (Participants with clinical history of learning disorders will be allowed to participate as long as the disorder does not impact their ability to participate based on PI judgement).
• Current treatment with any non-stimulant medication for ADHD (e.g., atomoxetine, clonidine, guanfacine).
• Current treatment with other psychoactive drugs.
• Participant is currently considered at risk for attempting suicide by the Investigator, or is currently demonstrating active suicidal ideation or self-injurious behavior, as measured by MINI-KID Suicidality Module C.
• Documented hearing loss.
• Recent history or suspicion (within the past 6 months) of substance abuse or dependence.
• Any other medical condition that, in the opinion of the Investigator, may confound study data/assessments.

Arm && Interventions

Group	Intervention	Description
Noise cancelling headphone first, then sham control headphone	Use of Noise Cancelling Headphones	This group will use the noise cancelling headphone during the first experimental session as they complete study assessments. They will then return within a week, for experimental session day 2, to complete the same assessments this time using a sham control headphone.
Sham control headphone first, then noise cancelling headphone	Use of Noise Cancelling Headphones	This group will use the sham control headphone during the first experimental session as they complete study assessments. They will then return within a week for experimental session day 2, to redo the same assessments this time using a noise cancelling headphone.

Primary Outcome Measures

Name	Time	Method
Change in CANTAB ADHD Battery - Motor Control Task	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare change from Baseline scores on the Cambridge Automated Neuropsychological Test Battery (CANTAB) ADHD battery with noise cancelling headphones and sham-controls. Results are reported as change from Baseline for each of 4 components of the ADHD battery.; Motor Control Task: no minimum and maximum values as values are reaction times; positive scores indicate slower reaction times compared to baseline; lower scores indicate faster reaction times compared to Baseline
Change in CANTAB ADHD Battery - Stop Signal Reaction Time Task	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare change from Baseline scores on the Cambridge Automated Neuropsychological Test Battery (CANTAB) ADHD battery with noise cancelling headphones and sham-controls. Results are reported as change from Baseline for each of 4 components of the ADHD battery.; Stop Signal Reaction Time Task: no minimum and maximum values as values are reaction times; higher scores indicate worse performance compared to Baseline
Change in CANTAB ADHD Battery - Rapid Visual Processing Task	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare change from Baseline scores on the Cambridge Automated Neuropsychological Test Battery (CANTAB) ADHD battery with noise cancelling headphones and sham-controls. Results are reported as change from Baseline for each of 4 components of the ADHD battery.; Rapid Visual Processing Task: no minimum and maximum values as values are number of correct hits; higher scores indicate better performance compared to Baseline
Change in CANTAB ADHD Battery - Spatial Working Memory Task	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare change from Baseline scores on the Cambridge Automated Neuropsychological Test Battery (CANTAB) ADHD battery with noise cancelling headphones and sham-controls. Results are reported as change from Baseline for each of 4 components of the ADHD battery.; Spatial Working Memory Task: no minimum and maximum values as values are number of errors; higher (positive) scores indicate more errors compared to Baseline

Secondary Outcome Measures

Name	Time	Method
Change in Academic Productivity Measures -Math	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare change from Baseline scores on academic productivity measures (math) - Math Fluency and Calculation Tests (MFACTS) Calculation age standard score; This scale measures an individual's ability to complete age/grade referenced math problems in a set amount of time; higher scores indicate better performance compared to Baseline; standard scores are norm-referenced and have a mean of 100 and a standard deviation of 15. Scores reported here are changes for an individual and can theoretically range from -50 to +50. A higher score indicates better performance in that condition compared to Baseline - ie., better mathematical calculation ability
Subjective Reports of Experience	Experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compare the self-reports of noise cancelling headphones versus sham controls - How much did the headphones help you concentrate; self-reported ratings scale with 1 being "not at all" and 10 being "extremely"; higher scores indicate that participants reported better concentration during the session for each condition
Change in Academic Productivity Measures -Reading Comprehension	Baseline, experimental session 1 (3-7 days after baseline), experimental session 2 (3-7 days after experimental session 1)	Compares change from Baseline in Test of Silent Reading and Comprehension (TOSREC) Index score across groups; higher scores indicate better performance compared to Baseline; This scale measures an individual's ability to answer questions about an age/grade referenced reading passage in a set amount of time; higher scores indicate better performance compared to Baseline; Index scores are norm-referenced and can be interpreted similar to standard scores with a mean of 100 and a standard deviation of 15. Scores reported here are changes for an individual and can theoretically range from -50 to +50. A higher score indicates better performance in that condition compared to Baseline - ie., better reading comprehension ability
