title: Revisiting the latent structure of the anxiety sensitivity construct: more evidence of dimensionality.
abstract: Anxiety sensitivity (AS) was initially conceptualized as existing along a continuum; however, emerging evidence from taxometric analyses is mixed as to whether the latent structure of AS is dimensional or taxonic. The purpose of the present study was to further evaluate the latent structure of AS in an effort to clarify the contrasting findings reported in the literature. To do so, we examined the latent structure of AS in two large independent samples unselected with regard to AS level (comprising undergraduate respondents and/or community residents). MAXEIG and MAMBAC analyses were performed with indicator sets drawn from distinct self-report measures of AS within either sample. MAXEIG and MAMBAC, as well as comparison analyses utilizing simulated taxonic and dimensional datasets, yielded converging evidence that AS has a dimensional latent structure. Implications of these finding for the conceptualization and measurement of AS are discussed and future research directions are highlighted.
