The Health Belief Model (HBM)3 has been demonstrated to be a useful
framework for assessing the attitudes of primary care physicians (PCPs)
toward hearing rehabilitation for older patients.4
This study aimed to use the HBM to examine attitudinal factors that might
influence ENT physicians’ recommendations and decisions to refer older
patients for hearing aids and cochlear implants. Furthermore, the attitudes of
ENT physicians in this study were compared to the attitudes of PCPs in the
Gilliver and Hickson study.4
Susceptibility
ENT physicians expressed neutral
attitudes about their older patients’
susceptibility to hearing loss (M =
3.06).
Participants
• 147 ENT physicians were recruited from one local hospital and four
physician conferences held in Missouri, Illinois, and Georgia.
• A total of 46 surveys were returned; 39 were usable (31.3% response rate).
Procedure
• The survey was distributed by two methods: (a) paper survey distributed at
the conferences and at the local hospital, (b) online survey distributed to
ENT physicians’ email addresses after attending the conference.
• Independent samples t-test was used for comparison between groups.
There were no significant differences in their attitudes in perceived susceptibility,
severity, and barriers.

CONCLUSIONS
• Generally, ENT physicians were aware of the high susceptibility and
the severity of hearing loss in older patients, and had positive attitudes
toward the benefits of hearing aids and cochlear implants for this
population.
• However, ENT physicians expressed a high level of concern about their
older patients’ ability to afford and adjust to these devices.
• When compared with PCPs, ENT physicians had more positive
attitudes toward the benefits of hearing aids and cochlear implants, and
had higher levels of self-efficacy for referral (p < .001).
• ENT physicians and audiologists should collaborate to develop
outreach educational programs for PCPs on current intervention
options, especially cochlear implants, and their potential benefits to the
hearing impaired elderly.
• Both ENT physicians and PCPs believed that older patients have
difficulty in affording and adjusting to hearing aids and cochlear
implants. These beliefs may affect their decisions to refer patients for
audiological services.

Barriers
ENT physicians had negative
perceptions about the ability of older
patients to use hearing aids and
cochlear implants (M = 2.49).

• Comparison between groups revealed
that ENT physicians whose offices
provide cochlear implant services had
more positive attitudes toward the
benefits of cochlear implants than
those whose do not (p=.022).

% of responses
ENT physicians believed that hearing
loss has serious consequences on
their older patients’ lives (M = 3.95).
• They believed that patients would have
difficulties with cost, stigma, and
adaptation to the use of devices.

% of responses
• Each HBM item required participants to respond on a 5-point scale,
ranging from strongly disagree (1) to strongly agree (5).
• Mean scores for each HBM construct were calculated from items in
that construct.
ENT physicians had more positive attitudes in the areas of perceived benefits,
t(38) = 7.43, p < .001; and self-efficacy, t(38) = 5.92, p < .001.

• The survey was adapted from a previously published questionnaire, which
was developed based on the HBM constructs.4
• 22 statements measured attitudes toward hearing aids and cochlear
implants for older adults via five HBM constructs (see Figure 1).

RESULTS
INTRODUCTION
Hearing aids and cochlear implants are an effective intervention for older
people with hearing impairment.1 However, adoption of these devices among
the older population has remained low.2
