Conditions sleep apnea, obstructive, patient compliance
Treatments tailored, usual care
Phase phase 1
Sponsor Milton S. Hershey Medical Center
Collaborator National Institute of Nursing Research (NINR)
Start date November 2011
End date February 2014
Trial size 72 participants
Trial identifier NCT01454830, 37007, 4R00NR011173


The purpose of this study is to examine the feasibility of a tailored (i.e., individualized) intervention to promote adherence to continuous positive airway pressure therapy (CPAP) in adults with newly-diagnosed, CPAP treated, obstructive sleep apnea.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking double blind (subject, investigator, outcomes assessor)
Primary purpose treatment
Tailored, or individualized, intervention addressing patient education, skills training, and cognitive perceptions
tailored Individualized
Individualized on critical indicator (Self-efficacy measure in Sleep Apnea) measured at each intervention delivery period (pre-diagnosis, immediately post-diagnosis, post-CPAP titration, and during week 1 of home CPAP treatment. Intervention components include patient education, preparatory skills training, modification of inaccurate/unrealistic cognitive perceptions of risk, outcome expectations, and treatment self-efficacy
(Active Comparator)
The comparison group, usual care, includes the standard of care delivered to all newly-diagnosed OSA persons proceeding to CPAP treatment
usual care standard of care
Usual care comparison group will proceed from initial clinical evaluation for OSA, diagnosis by polysomnography, CPAP titration polysomnography, and home CPAP treatment initiation as per current standard of care

Additional Information

Official title Phase I Double-blind Randomized Controlled Trial: Sociocultural and Cognitive Perception Intervention to Promote Positive Airway Pressure Adherence
Principal investigator Amy M Sawyer, PhD
Description Poor adherence to CPAP is a significant problem among OSA patients resulting in suboptimal health and functional outcomes. Intervention studies to promote CPAP adherence have shown relatively small effects in selected samples and were costly. The overall objective of this research is to examine the effect, feasibility, and acceptability of a tailored intervention on CPAP adherence among adults with newly-diagnosed, CPAP treated OSA. The central hypothesis is that critically timed tailored interventions that focus on sociocultural aspects and cognitive perceptions of the individual experience with OSA diagnosis and treatment will improve overall CPAP adherence rates. The pilot randomized controlled trial will examine CPAP adherence outcomes at 1wk, 1mo, and 3mo among those randomly assigned to the tailored intervention or usual (standard) care and examine specific feasibility and participant acceptability outcomes in order to design and conduct a subsequent larger randomized controlled trial testing the overall efficacy of the tailored intervention.
