Procedure
The study was administered online via Microsoft Teams and Qualtrics (Provo, UT). Participants attended an initial session during which they provided informed, written consent, demographic information, and were interviewed using the MINI-Plus for screening and diagnostic purposes. The first session lasted an average of 45 minutes. Eligible participants were invited to a second session (within one week) during which they completed baseline questionnaires and the AMT extended version. Measurements were completed in the following order: i) DASS, ii) RRS, iii) SCS, iv) VAS, v) self-discrepancy induction, vi) VAS, vii) AMT extended version. Following completion of baseline measures, participants were randomly allocated by the lead researcher, using Simple Randomisation, to either the LKM or colouring group and were introduced to the treatment. A distraction task was subsequently administered that asked participants to spend three minutes thinking about neutral situations from a list of thirty (e.g. think about the colour of clouds). This second session lasted an average of 45 minutes. Within one week of treatment completion, participants were reassessed on all baseline measures and were then debriefed on the nature of the study. Participants in the colouring group were subsequently invited to learn the meditation and access the Moodle recordings. The final session lasted an average of 40 minutes.
