About this trial
This study is conducted entirely in person at California State University, San Bernardino. Participation requires 12 campus visits over six weeks. Remote participation is not available, and travel expenses are not reimbursed. Participants who complete all study visits will receive a gift valued at $25.
This study will evaluate the feasibility and potential effects of a six-week, music-based binaural beats stimulation program in adults with attention-deficit/hyperactivity disorder (ADHD). Forty adults with ADHD will be randomly assigned to either a binaural beat stimulation group or a control group. Both groups will attend 12 supervised listening sessions over six weeks and listen to similar music for 20 minutes per session; however, only the intervention group's music will contain embedded binaural beats. Cognitive assessments will be completed before and after the intervention to evaluate changes in attention and memory. Session attendance and participant retention will also be examined to assess the feasibility and acceptability of the program.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers

Willing to wear headphones during the listening sessions
Able and willing to attend 12 listening sessions at the CSUSB campus conducted twice weekly over six weeks -

Treatments tested in this trial
Music-Based Binaural Beats Stimulation
BehavioralParticipants will receive 12 supervised binaural beats stimulation sessions over six weeks, with two sessions conducted per week. During each session, participants will listen through headphones to 20 minutes of music containing embedded binaural beats. Music will be selected based on each participant's preferred genre from available options.
Music Listening Without Binaural Beats
BehavioralParticipants will receive 12 supervised music-listening sessions over six weeks, with two sessions conducted per week. During each session, participants will listen through headphones to 20 minutes of music without embedded binaural beats. The music, listening duration, session schedule, setting, and available genre options will be similar to those provided to the experimental group.
Treatment groups
Trial outcomes
Primary outcomes
Intervention Feasibility
Feasibility will be evaluated using the numbers of participants screened, eligible, and enrolled; the proportion of enrolled participants who complete the intervention and post-intervention assessments; and the number and percentage of the 12 scheduled listening sessions completed by each participant.
Participant Acceptability
Acceptability will be assessed during each intervention session by documenting changes in health status, perceived positive or negative effects, and any discomfort or concerns. After each session, participants will rate their enjoyment on a 5-point scale ranging from 1 (not at all enjoyable) to 5 (extremely enjoyable) and provide open-ended feedback about their mood, emotions, relaxation, and other perceived effects. Responses will be summarized descriptively.
Secondary outcomes
Change in Attention Performance
Change from baseline in attention-related performance measured using the CogniFit cognitive assessment battery, including the Psychomotor Vigilance Test, Stroop Test, and Divided Attention Test. Changes of the scores will be interpreted according to the scoring method for each CogniFit test.
Change in Memory Performance
Change from baseline in memory-related performance measured using the CogniFit cognitive assessment battery, including the Visual Working Memory Span Test and Multimodal Lexical Memory Test. Changes of the scores will be interpreted according to the scoring method for each CogniFit test.
