Goal-Directed Episodic Future Thinking as an Online Intervention to Reduce Frequent Cannabis Use — preregistered 3-arm RCT: Public Analysis Data and Reproducibility Materials

This repository contains the anonymized, analysis-ready dataset and reproducibility materials accompanying the study “Goal-Directed Episodic Future Thinking as an Online Intervention to Reduce Frequent Cannabis Use: A Preregistered Online Three-Arm Randomized Controlled Trial.” The deposit includes the public SPSS dataset, analysis syntax, variable codebook, and JASP files for the Bayesian primary-outcome comparisons. The materials reproduce the analyses reported in the manuscript and Supplementary Materials from the final analysis-ready stage onward. Upstream processing of the original Qualtrics exports is not included because the source data contain information that is not publicly released. The final analytic sample consists of 151 participants allocated to Goal-EFT, Standard EFT, or Episodic Recent Thinking (ERT). The study was preregistered at OSF: https://osf.io/8dzsr/overview.
