Measuring impatience: Elicited discount rates and the Barratt Impulsiveness Scale

Measuring Impatience: Elicited Discount Rates and the Barratt Impulsiveness Scale

We explore intertemporal decision making to test the extent to which elicited discount rates and a self-reported scale of impatience measure the same behavioral characteristic. We conduct experiments in which we elicit discount rates using monetary rewards and a self-reported measure of impatience (the Barratt Impulsiveness Scale, BIS-11). Although researchers have utilized these measures to in...

Unpacking experimental discount rates: Impatience, uncertainty, and credit constraints

Validity and Reliability of the Abbreviated Barratt Impulsiveness Scale in Spanish (BIS-15S).

OBJECTIVE: This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. METHOD: The BIS-15S was tested in non-clinical (n=283) and clinical (n=164) native Spanish-speakers. Intra-scale reliability was calculated using Cronbach's α, and test-retest reliability was measured with Pearson correlations. P...

Impulsivity and overeating: a closer look at the subscales of the Barratt Impulsiveness Scale

Impulsivity can be defined as a predisposition toward rapid, unplanned reactions to internal or external stimuli regardless of negative consequences of these reactions for the impulsive individual or for others (Moeller et al., 2001). It is a multifaceted construct and there is a range of methods available for its measurement. Two of the most often used methods are selfreport instruments and be...

Psychometric properties of the Barratt Impulsiveness Scale in patients with gambling disorders, hypersexuality, and methamphetamine dependence.

Although the Barratt Impulsiveness Scale (BIS; Patton, Stanford, & Barratt, 1995) is a widely-used self-report measure of impulsivity, there have been numerous questions about the invariance of the factor structure across clinical populations (Haden & Shiva, 2008, 2009; Ireland & Archer, 2008). The goal of this article is to examine the factor structure of the BIS among a sample consisting of t...
