The Hall index of mystical spirituality: an exploration in constructing a short scale of mystical spirituality

ABSTRACT

The aim of this study was to propose a new nine-item measure of mystical spirituality which would be as easy as possible] for “ordinary” people (those with little or no theological education) to complete. The measure was developed and tested on data provided by 602 participants within an on-line survey. The Hall Index of Mystical Spirituality displayed excellent properties of internal consistency reliability (reporting an alpha coefficient of .93) and good construct validity, in terms of its location within the four components of psychological space, defined by psychological type theory (reporting a correlation of .30 within the measure of intuition). As a new measure of mystical spirituality further research is needed to test the usefulness of this short scale.
