A measure of within-participant response consistency

Abstract: In this article, we introduce a measure of withinparticipant response consistency for use in the analysis of performance in decision-making tasks. The measure is an estimate of the correlation between the responses associated with two identical blocks of trials, the second of which has yet to be conducted. We derive a formula for the measure that can be applied to data from any two-choice decision task, including yes/no detection and two-alternative forced choice (2AFC). The estimate is easily calculated from … Show more

“…A high degree of uniformity in adolescents' responses to directly and indirectly phrased questions may imply that adolescents perceive these questions as asking about the same past behavior. High degree of consistency in item-level responding also suggests a lack of specific measurement errors that indicate individuals are interpreting particular items differently than other items intended to get at the same construct (MacDonald & Trafimow, 2013). To this end, findings appear to support the within-participant response consistency for suicide attempt questions for the majority of the sample.…”

“…Another important aspect of ethical decision-making is the consistency of an individual's decisions. Internal consistency is a measure of the degree of variance in an individual's response to the same stimulus over time (MacDonald & Trafimow, 2013). One study by Holyoak and Simon (1999) on judicial decision-making required participants to rate their agreement with several pieces of information presented to them before and after evaluating a legal case.…”

“…To overcome this issue, we decided against randomly splitting the data and calculated the correlation between the number of switches for the first half of the trials and the second half of the trials per subject. This might serve as a proxy and an easy and interpretable measure of subjects' response contingency (MacDonald & Trafimow, 2013) for which we do not report Spearman-Brown corrected values given its potential imprecision.…”
