A Computer Adaptive Measure of Delay Discounting

Do the adjusting-delay and increasing-delay tasks measure the same construct: delay discounting?

Delay discounting describes the subjective devaluation of a reward when it is delayed. In animals, the adjusting-delay (AD) and increasing-delay (ID) tasks often are used to assess individual differences in, and drug effects on, delay discounting. No study to date, however, has compared systematically the measures of discounting produced in these tasks. The current study examined the correlatio...

A Delay Discounting Model of Psychotherapy Termination

Delay discounting (DD) procedures are emerging as an important new method for psychotherapy researchers. In this paper a framework for conceptualizing existing, seemingly discrepant, research findings on termination is introduced and new directions for research are described. To illustrate the value of a DD framework, the common psychotherapy problem of premature termination is addressed. First...

Delay discounting in schizophrenia.

BACKGROUND It is well known that individuals with schizophrenia have dopaminergic abnormalities as well as memory-related difficulties, both of which are associated with impulsive decision making. We used a delay discounting measure to test the degree to which patients make future-oriented decisions. METHODS 42 patients with schizophrenia and 29 healthy participants completed a delay discount...

A Delay Discounting Measure of Great Expectations and the Effectiveness of Psychotherapy

Many clients prematurely terminate therapy before they have recovered. One possible explanation for treatment dropout is unmet expectations. Although the effects of unmet role expectations have received much attention in the literature, little is known about unmet outcome expectations. Two studies were designed to look at duration and effectiveness outcome expectations held by individuals withi...
