↵* All values are mean ± standard deviation. Time 1 indicates 4 weeks after treatment initiation; time 2 indicates 8 weeks after treatment initiation; time 3 indicates 12 weeks after treatment initiation.
↵† Mean of event-contingent recording reports within each assessment wave (i.e., each monthly 1-week assessment) for each participant; behaviour assessments were multiplied by 10 to enable computational models.
