Evaluation of the speech dialect attitudinal scale

Listener groups employed the Speech Dialect Attitudinal Scale (SDAS) to rate speakers in a variety of situations. These involved: (A) foreign accent, (B) regional dialect, (C) speech pathology, (D) broadcast news reporting, and (E) use of obscene language. Reliability of ratings was consistently high, with a median of .98. Evidence of construct validity was provided by the factor structures of SDAS item scores. Except in the case of the speech pathology experiment, the factor analyses yielded a remarkably consistent three‐factor structure: Socio‐Intellectual Status, Aesthetic Quality, and Dynamism. In each case, analyses of variance and covariance of SDAS scores discriminated among speakers differentiated by linguistic variation, further supporting the validity of SDAS data.
