title: Psychometric evaluation of the Beck anxiety inventory: a sample with sleep-disordered breathing.
abstract: This study aimed to document the psychometric properties of the Beck Anxiety Inventory (BAI) within a population with sleep-disordered breathing (SDB), given concerns about overlapping symptomatology between anxiety and sleep apnea. Results supported good internal consistency and convergent and discriminant validity for the BAI and a single-factor solution for men, women, and the total sample. Women had higher scores than men, and discriminant analyses differentiated men from women based on item responses. The BAI has acceptable reliability and validity within a SDB population, supporting its use as a gauge of anxiety severity in individuals with SDB. This is a preliminary study to measure anxiety severity in SDB; future research is needed to determine the utility of the BAI as a diagnostic screener.
