title: The investigation of exposure and cognitive therapy: comment on Tarrier et al (1999).
abstract: This article outlines concerns relating to the N. Tarrier et al. (1999) investigation comparing imaginal exposure and cognitive therapy. Specifically, the authors offer N. Tarrier et al. the opportunity to operationally define and clarify the claim that more patients treated by imaginal exposure "worsened" during treatment. Equally, in light of N. Tarrier et al.'s low effect sizes in relation to past research the authors also highlight the need to utilize accountable treatment integrity checks.
