Mindfulness meditation and self-monitoring reduced maladaptive daydreaming symptoms: A randomized controlled trial of a brief self-guided web-based program.

OBJECTIVE

Maladaptive daydreaming (MD) is a compulsive form of daydreaming that causes distress and functional impairment. We present the first treatment trial for MD.

METHOD

We tested the effectiveness of an eight-session internet-based self-help training for mindfulness and self-monitoring and compared three groups across three measurement points in time. A sample of 557 people was randomly assigned. A total of 353 participants (age [] = 28.3[10.5], 76% female, 77% unmarried) completed our program: full-intervention group ( = 114, psychoeducation + motivation enhancement + mindfulness + self-monitoring), partial-intervention group ( = 125, identical excluding self-monitoring), and waiting-list group (n = 125, internet-based support as usual).

RESULTS

All MD measures assessing daydreaming pathology, daydreaming frequency, and life functioning showed significant improvement with a large effect size (ES) from baseline to posttreatment in both intervention groups, whereas the wait-list group showed no significant improvement, MD: (3, 349) = 35.76, < .0001, η² = 0.24; frequency: (3, 349) = 32.06, < .001, η² = 0.22; functioning: (3, 349) = 20.43, < .001, η² = 0.15. Mindfulness with self-monitoring training for MD was superior to mindfulness alone in the short term, but they both were equally efficient in the long term. Both interventions were superior to relying on internet-based support forums only. The clinically significant improvement rate of mindfulness with self-monitoring training was 24%, while the reliable improvement rate reached 39%. At the 6-month follow-up, achievements were maintained.

CONCLUSIONS

A brief internet-based intervention program comprising mindfulness meditation and self-monitoring facilitated recovery or improvement in many individuals with MD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
