Lessons unlearned: A conceptual review and meta-analysis of the relationship between the Attention Control Scale and Objective Attention Control.

Attention control is central to many models of emotion. Among the most common measures of attention, control is the Attention Control Scale (ACS), which has exerted considerable influence in terms of the volume and breadth of research findings, with its use in cognitive-experimental research continuing to increase in recent years. However, there are growing concerns about whether the ACS genuinely indexes attention control. The present paper considers the context and development of the ACS, reviews and meta-analyses the available evidence regarding its association with objective measures of attention control. Meta-analytic results from nine studies (total  = 1274) indicated that the full-scale ACS was not significantly associated with behavioural measures of attentional control ( = .067, = .093,  = 1274, 95% CI: -.011, .145). Findings indicated likely missing studies with lower correlations suggesting the true association may be smaller. Limited evidence of shared variance between subjective and objective measures of attention control contrasts with considerable evidence that the scale is closely correlated with dispositional traits (e.g. anxiety, agreeableness) that could plausibly influence responding. Thus, on the balance of current findings, we conclude that there is little compelling evidence that responding on the ACS reflects genuine attention control abilities.
