Predictors and patterns of insomnia symptoms in OSA before and after PAP therapy.

Objective: Identify factors that predict improvement versus persistence of insomnia symptoms following treatment of obstructive sleep apnea (OSA) with positive airway pressure (PAP) therapy.

Methods: Archival data from 68 PAP-treated sleep apnea patients aged 25-83 were analyzed using nonparametric tests and stepwise regression to assess the relationships between insomnia symptoms, multiple OSA variables, and PAP use over time.

Results: Pretreatment insomnia symptom severity (ISS; b = -0.
