Results of the confirmatory factor analysis (Table 2) demonstrated strong support for the same underlying structure as with the full BAES: four distinct factors representing distinct stimulation and sedation constructs at ascending and descending limbs (Model One). There was no support for the two-factor models based on limb (Model Two) or effect (Model Three), or for the one-factor model (Model Four). In other words, there was no support for combining stimulation and sedation into one construct, or collapsing assessments from ascending and descending limbs into one timeframe. Stimulation and sedation as distinct constructs at peak BrAC was also supported (Model Five). All together, results from Study One support the use of the B-BAES at ascending, peak, and descending limbs of the breath alcohol curve.
