A unified online test battery for cognitive impulsivity reveals relationships with real-world impulsive behaviours

Abstract

Impulsive behaviours are a major contributor to the global burden of disease, but existing measures of cognitive impulsivity have suboptimal reliability and validity. Here, we introduce the Cognitive Impulsivity Suite, comprising three computerized/online tasks using a gamified interface. We conceptualize rapid-response impulsive behaviours (disinhibition) as arising from the failure of three distinct cognitive mechanisms: attentional control, information gathering and monitoring/shifting. We demonstrate the construct and criterion validity of the Cognitive Impulsivity Suite in an online community sample (N = 1,056), show test–retest reliability and between-subjects variability in a face-to-face community sample (N = 63), and replicate the results in a community and clinical sample (N = 578). The results support the theoretical architecture of the attentional control, information gathering and monitoring/shifting constructs. The Cognitive Impulsivity Suite demonstrated incremental criterion validity for prediction of real-world, addiction-related problems and is a promising tool for large-scale research on cognitive impulsivity.

JTC = Jumping to conclusions task. Median Beads = median number of beads drawn before a decision is made (aggregated across blocks with probabilities 85:15 and 60:40). Factor scaling was performed using the reference variable method. Standardised estimates appear in bold typeface. Unstandardised estimates are in normal typeface below. Bootstrapped standard errors (10,000 posterior draws) appear in brackets. Threshold for statistical significance for associations with the median beads drawn on the JTC tasks and the other latent variables using the Adjusted Bonferroni procedure (AB2; \(\alpha _{per\,test} = \frac{{\alpha _{familywise}}}{{k^{1 - \sqrt {\left| {\overline {r_j} } \right|} }}}\) was α < .024.

The latent correlations between the Monitoring / Shifting factor and the five self-reported impulsivity factors have been omitted from the figure for clarity. These were Negative Urgency (ϕ = -.134, SE = .038, [95%BCI = -.201, -.050], p < .001); Lack of Perseverance (ϕ = -.037, SE = .041, [95%BCI = -.128, .036], p = .377); Lack of Premeditation (ϕ = -.154, SE = .039, [95%BCI = -.228, -.071], p < .001); Sensation Seeking (ϕ = -.110, SE = .040, [95%BCI = -.185, -.028], p = .006); Positive Urgency (ϕ = -.278, SE = .037, [95%BCI = -.348, -.204], p < .001).
