Abstract
Temporal discounting (TD) tasks measure the preference for immediate rewards over larger delayed rewards and have been widely used to study impulsivity in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). Relatively impulsive individuals tend to show high inconsistency in their choices, which makes it difficult to determine commonly used TD outcome measures (e.g., area under the curve, AUC). In this study, we leveraged two published datasets to compare four methods to compute TD outcome measures in children and adolescents (8-17 years) with (n = 107) and without ADHD (n = 128): two predetermined rules methods, a proportion method, and logistic regression. In both datasets, when using the two predetermined rules methods and the proportion method, TD outcomes were highly correlated and group differences in TD were similar. When using logistic regression, a large proportion of AUCs (95% in dataset 1; 33% in dataset 2) could not be computed due to inconsistent choice patterns. These findings indicate that predetermined rules methods (for studies with small sample sizes and experienced raters) and a proportion method (for studies with larger sample sizes or less experienced raters) are recommended over logistic regression when determining subjective reward values for participants with inconsistent choice patterns.
期刊介绍:
The purposes of Child Neuropsychology are to:
publish research on the neuropsychological effects of disorders which affect brain functioning in children and adolescents,
publish research on the neuropsychological dimensions of development in childhood and adolescence and
promote the integration of theory, method and research findings in child/developmental neuropsychology.
The primary emphasis of Child Neuropsychology is to publish original empirical research. Theoretical and methodological papers and theoretically relevant case studies are welcome. Critical reviews of topics pertinent to child/developmental neuropsychology are encouraged.
Emphases of interest include the following: information processing mechanisms; the impact of injury or disease on neuropsychological functioning; behavioral cognitive and pharmacological approaches to treatment/intervention; psychosocial correlates of neuropsychological dysfunction; definitive normative, reliability, and validity studies of psychometric and other procedures used in the neuropsychological assessment of children and adolescents. Articles on both normal and dysfunctional development that are relevant to the aforementioned dimensions are welcome. Multiple approaches (e.g., basic, applied, clinical) and multiple methodologies (e.g., cross-sectional, longitudinal, experimental, multivariate, correlational) are appropriate. Books, media, and software reviews will be published.
