Comparing Random Allocation and Allocation by Preference to Mindfulness Practice

Change from baseline (T0) to post-intervention (T2) on the Toronto Mindfulness Scale, State Version (TMS-SV; Lau et al., 2006).

The goal of this randomized controlled study is to examine whether allocation based on
 preference to one of two brief mindfulness meditation practices (mindfulness of the breath or
 mindfulness of sounds) influences the potentially beneficial effects of these practices, and
 influences participants' intention to engage in further mindfulness practice. To the end,
 members of the general public will be randomly assigned to one of three groups: (1) a group
 in which they choose which of the two mindfulness practices they do; (2) a group in which
 they are randomly allocated to do one of the mindfulness practices; and (3) a control group
 that listens to an audiobook extract. The level of mindfulness of each group will be
 compared, along with some other outcomes.
