Abstract

McDowall, Loftin, and Wiersma (1996) avoid our criticisms of the univariate interrupted time series design (ITSD) by misstating our criticisms, by addressing what they claim we ''implied'' rather than what we plainly stated, and by ignoring crucial points in our article in this issue (Britt et al. 1996). We reiterate: McDowall et al.'s (1992) conclusions regarding the alleged efficacy of the Washington, D.C., handgun ban (mislabeled by McDowall et al. as a licensing law) collapsed once any of three improvements were made to their analysis: (1) use of a more appropriate control series, (2) use of a more appropriate, theoretically based specification of the intervention model, and (3) use of an alternative, extended time series beyond the period studied by McDowall et al. (1992). Nothing McDowall et al. (1996) write has rebutted our assertions.
