Question 104

Clinical Trial Description

A researcher investigated the effectiveness of different psychological interventions for generalized anxiety disorder. 180 patients initially completed a standardized clinical anxiety scale ranging from 1 (no anxiety) to 20 (severe anxiety).

80 patients who scored between 14 and 16 (indicating moderate-to-high anxiety) were selected to participate in a clinical trial. They were randomly allocated to one of three conditions:

  • Condition 1 (Standard MBSR): Attending eight weekly 2-hour physical group sessions of Mindfulness-Based Stress Reduction.
  • Condition 2 (Digital App): Using a self-guided digital mindfulness app for 15 minutes daily over an eight-week period.
  • Condition 3 (Waiting List Control): Placed on an eight-week waiting list, receiving no active mindfulness training during this time.

After the eight-week period, all participants completed the anxiety scale again so researchers could analyze changes in symptom severity.

Question

The researcher asked the 80 patients for fully informed consent to take part in this trial. Outline what the researcher should have told the patients so that they were able to give genuinely informed consent.
