Loving Kindness Meditation zur Behandlung der chronischen Depression
Behandlungskonzept und Ergebnisse einer Pilot-Studie
Abstract
Zusammenfassung.Theoretischer Hintergrund: Chronische Depressionen gehen mit einer langwierigen Belastung einher und verursachen hohe Krankheitskosten. Ein möglicher Ansatz zur Behandlung könnte die Loving Kindness Meditation (LKM) sein. Methode: In dieser Pilot-Studie wurde ein LKM-Gruppenprogramm eingesetzt und bezüglich der Effektivität untersucht. N = 2207 Fälle aus Wartelistendaten wurden stufenweise zu der LKM-Gruppe (n = 12) zugeordnet. Zwei Kontrollgruppen (n = 134 und n = 12) wurden gebildet, indem zunächst die Ein-und Ausschlusskriterien angewandt wurden und dann die verbliebene Stichprobe basierend auf der Kovariatenverteilung mittels Propensity Score Matching (PSM) angepasst wurde. Die Gruppen wurden anhand des OQ-30 verglichen. Ergebnisse: Im Prä-Post-Vergleich zeigten sich im OQ-30 signifikante Verbesserungen. Allerdings zeigte sich das so nicht in den symptomspezifischen Instrumenten (BDI-II und HAM-D). Im Vergleich zu der gesamten Wartelistenstichprobe (n = 134) ergaben sich signifikante Verbesserungen im OQ-30. Verglichen mit der PSM-Wartelistenkontrollgruppe zeigten sich marginal signifikante Unterschiede im OQ-30, signifikante Unterschiede konnten bezüglich der Depressionsitems des OQ-30 nachgewiesen werden. In der Interventionsgruppe ergaben sich mehr reliable Verbesserungen im OQ-30 als in den Wartelistenkontrollgruppen. Schlussfolgerung: Die Pilotstudie zeigte eine geringere Abbruchquote als Vorgängerpilotstudien und eine gute Prä-Post Effektstärke im OQ-30, sowie im Vergleich zu den beiden Wartelistekontrollgruppen. Allerdings zeigten sich keine konsistenten Prä-Post Effekte in den Depressionsskalen. Eine weitere umfangreichere Studie mit aktiver Kontrollgruppe wäre nötig, um das Programm hinsichtlich seiner Effektivität, bezüglich des Abbruchs sowie der Heterogenität der Effekte in den Depressionsskalen weiter untersuchen zu können.
Abstract.Background: Chronic depression is associated with much psychological distress and causes great financial burden. A treatment approach that might be effective is loving kindness meditation (LKM). Method: An LKM approach was employed and evaluated in this pilot study, in which 2,207 patients on a waiting list were matched stepwise to patients undergoing LKM (n = 12). Two control groups were generated by first applying the inclusion and exclusion criteria (n = 134) and then using propensity score matching (PSM) to adjust the remaining sample based on covariate distributions (n = 12). The groups were compared using the Outcome Questionnaire-30 (OQ-30). Results: In the pre–post comparison, significant improvements were found in the OQ-30. However, this was not the case for the symptom-specific instruments (Beck Depression Inventory-II [BDI-II] and the Hamilton Depression Rating Scale [HAM-D]). Compared with the full waiting list sample (n = 134), there were significant improvements in the OQ-30. Compared with the PSM sample, there were marginally significant differences in the OQ-30; significant differences were detected with regard to the depression-related items of the OQ-30. There were more reliable improvements in the OQ-30 in the intervention group than in the control groups. Conclusion: The pilot study showed a lower drop-out rate than previous pilot studies and good pre–post effect sizes in the OQ-30, as well as good effect sizes compared with the two control groups. However, there were no consistent pre–post effects in the depression scales. A more extensive study with an active control group is needed to further investigate the program in terms of its effectiveness, drop-out, and heterogeneity of effects in the depression scales.
