Assessment name:  Spiritual Assessment Inventory

Scale overview: The Spiritual Assessment Inventory (SAI-2002) is a 48-item self-report measure of spiritual development (Hall & Edwards, 1996, 2002): Awareness of God and Quality of Relationship with God.

Authors: Hall & Edwards

Response Type: . Respondents rate each item on a five-point scale of personal truth (1= not at all true, 2 = slightly true, 3 = moderately true, 4 = substantially true, and 5 = very true).


The authors examined a large pool of items in several studies and identified the best items that measured the following five factors. The items are included in the 2002 reference.

Awareness of God (A)

Disappointment in Relationship with God (D)

Realistic Acceptance of God (R)

Grandiosity in Relationship with God (G

Instability in Relationship with God (I)


Psychometric properties

The authors provide evidence for internal consistency, test-retest reliability, construct validity, including concurrent validity. 

For example, there are significant correlations between each SAI subscale and spiritual wellbeing (SWBS). SAI subscales also significantly correlate with religious orientation: Intrinsic with all but G, Extrinsic social with all but I and Extrinsic personal with all but R. The authors also examined the relationship of the SAI with narcissistic personality (NPI). 

The SAI grandiosity subscale was significantly correlated with all three subscales of the NPI.
