Objectives: The objective
of this research is to evaluate whether a music intervention reduces anxiety
prior to gastrointestinal procedures.
Methods: Using an
experimental design, 198 veterans who were having a colonoscopy or
esophagogastroduodenoscopy were randomized to one of two intervention groups,
both of which occurred in procedure rooms: 1) 15 minutes of self-selected music
prior to GI procedure, and 2) 15 minutes of no music prior to the GI procedure.
Anxiety was tested before and after the 15-minute music or control intervention
using the 40-item Spielberger (1977) State-Trait Anxiety Inventory (STAI, state
and trait forms). Persons who
listened to music completed brief questions about their music enjoyment and
feelings of relaxation. Additionally,
autonomic responses and demographics were collected. Patients from both groups
were allowed to select music for the duration of their GI procedures.
Results: Patients were
randomized to music (n=100) or no music (n=98) using a table of random numbers.
Patientsí average age was 61 (SD 10.5, range 29-84), and 193 of the
patients were men. Most of the
patients usually listen to music in varying locations (n=198, 99%).
At baseline, the state anxiety mean score was the same for music and no
music groups (36). The patients in
the music intervention had significantly greater reduction in anxiety mean
scores after 15 minutes (31), compared to those who had no music (35), and the
difference between these scores was statistically significant (F=7.5, p=0.007).
There were no significant differences in blood pressure, pulse, or respirations,
which is consistent with other research. 97% stated they enjoyed the music and
89% stated they felt relaxed after listening. After the measurements for the
study, patients in both groups elected to listen to self-selected music for
enjoy selecting and listening to music. Results demonstrated that
patient-selected music effectively reduces anxiety in anticipation of GI
Impact: As a result of this study, the GI Diagnostic Center is encouraging all patients to select and listen to music while waiting for their GI procedures. This inexpensive and effective intervention is being studied for anxiety reduction in anticipation of vascular angiography.
