This is a summary of a brief presentation we put together fall 2014.
An early draft of the self report measure was published as part of the proceedings of Spirituality in the 21st Century: Journeys beyond Entrenched Boundaries in 2013.
We collected data during the 2013 Meditation course (RELB2165) at three time points: at the beginning, middle, and end of the course. Outcome: Many students were at floor for mental silence. As a consequnece, easier items were added to make the scale more broadly applicable. The data did not help clarify the factor structure underlying the the items. We continued to refine the wording.
In 2014, we administered an improved measure to the same course at the same three time points. The data seemed clean enough to analyze. We tried a continuous time model (Voelkle & Oud, 2013). Three time points is the minimum for this kind of model. The fit was unstable and difficult to intepret.
Progress is slow, but such delicate research takes time.
