Overview

Secondary analysis of a randomized controlled trial reveals links between delayed reward discounting and gambling severity, indicating challenges in adherence.

Key Points

  • This analysis aims to explore the relationship between delayed reward discounting and problem gambling, as well as its effects on adherence.
  • Conducted a secondary analysis of participants from the Win Back Control study (n = 345)
  • Evaluated delayed reward discounting using the Monetary Choice Questionnaire (MCQ)
  • Assessed gambling severity with the Problem Gambling Severity Index (PGSI) and gambling symptom severity using the Gambling Symptom Assessment Scale (G-SAS)
  • Delayed reward discounting is significantly associated with gambling symptom severity and problem gambling severity
  • Delayed reward discounting decreased weekly over three measurement points
  • Adherence was not predicted by delayed reward discounting
