Abstract [en]

Perfectionism can become a debilitating condition that may negatively impact functioning in multiple areas, including mental health. Prior research has indicated that Internet-based Cognitive Behavior Therapy (ICBT) can be beneficial, but few studies have included follow-up data. The current study explored the long-term outcomes of ICBT with guided self-help, delivered as two separate randomized controlled trials conducted in Sweden and the United Kingdom (UK). In total, 120 participants randomized to ICBT were included in both intention-to-treat and completer analyses, n = 78 (Swedish trial) and n = 62 (UK trial). Primary outcome measure was the Frost Multidimensional Perfectionism Scale, subscale Concern over Mistakes (FMPS CM). Secondary outcome measures varied between the trials and consisted of the Clinical Perfectionism Questionnaire (CPQ; both trials), the Patient Health Questionnaire – 9 Items (PHQ-9; Swedish trial), the Generalized Anxiety Disorder – 7 Items (GAD-7; Swedish trial), and the Depression Anxiety and Stress Scale – 21 Items (DASS-21; UK trial). Follow-up occurred after six months for the UK trial, and twelve months for the Swedish trial. Due to a number of differences in terms of baseline characteristics and study design, results were analyzed separately and not in combination. Analysis of Covariance revealed a significant difference between pre-treatment and follow-up in both cases. Intention-to-treat within-group effect sizes Cohen’s d were 1.21 (Swedish trial), 95% Confidence Interval (CI) [0.86, 1.54], and 1.24 (UK trial), 95% CI [0.85, 1.62] for the FMPS CM. Furthermore, 29 (59.2%; Swedish trial) and 15 (42.9%; UK trial) of the participants met criteria for recovery on the FMPS CM. Significant and moderate to large improvements were also found for the CPQ, the PHQ-9, the GAD-7, and the DASS-21. The results are promising for the use of ICBT as a way of targeting perfectionism, but the findings need to be replicated and include a comparison condition.
