Knowledge, Attitudes and Practice in Health, Obstructive Sleep Apnea, Physical Therapy.Abstract
Obstructive sleep apnea (OSA) is a highly prevalent
sleep breathing disorder. Its treatment encompasses an
interdisciplinary approach, with the physical therapist playing a
key role in the adaptation process, home titration, and monitoring
of patients who use continuous positive airway pressure.
This study developed and validated an instrument to assess the
knowledge and attitudes of physical therapists regarding OSA.
This is a methodological and multicenter study conducted in
all Brazilian regions. After the stages of construction, content
validation, and pre-testing, the instrument defined as OSAKQ-P
(OSA knowledge questionnaire for physical therapists), composed
of 26 knowledge items and three attitude items, was applied
electronically to a sample of 150 physical therapists. During
validation process, the following psychometric properties were
analyzed: internal consistency, content validity, construct validity
and test-retest reliability. The OSAKQ-P presented excellent
internal consistency (α= 0.84), excellent test-retest reliability
(ICC=0.90) and strong correlation with the auxiliary instrument
(r=0.753, p<0.001) evidencing its convergent validity. In addition,
the OSAKQ-P instrument detected differences between
knowledge in different Physical Therapy areas. The attitude
items presented low internal consistency (α=0.62), but detected
the difference in physical therapists’ attitudes according to their
clinical experience with OSA or lack thereof. The OSAKQ-P
instrument proved to be valid and reliable for assessing physical
therapists’ knowledge of OSA.
