Abstract [en]

Procrastination is a common self-regulatory failure associated with personal distress, but research investigating different treatment interventions for the condition is scarce. In the current study, 150 participants were randomized into guided self help, unguided self-help, and wait-list control. Outcome measures were administered before and after the treatment, or weekly throughout the treatment period, and the intention-to-treat principle was used for all statistical analyses. Mixed effects models revealed moderate between-group effect sizes comparing guided and unguided self-help to wait-list control; the Pure Procrastination Scale (Cohen’s d = 0.70, 95% CI [0.29, 1.10], and d = 0.50, 95% CI [0.10, 0.90]), and the Irrational Procrastination Scale (d = 0.81 95% CI [0.40, 1.22], and d = 0.69 95% CI [0.29, 1.09]). Clinically significant change was achieved among 31.3-40.0% for guided self-help, compared to 24.0-36.0% for unguided self-help. Neither of the treatment conditions was found to be superior on any of the outcome measures.
