A four-factor model of spiritual intelligence is first proposed. Supportive evidence is reviewed for the

capacities of critical existential thinking, personal meaning production, transcendental awareness,

and conscious state expansion. Based on this model, a 24-item self-report measure was developed

and modified across two consecutive studies (N = 619 and N = 304, respectively). The final version

of the scale, the Spiritual Intelligence Self-Report Inventory (SISRI-24), displayed excellent internal

reliability and good fit to the proposed model. Correlational analyses with additional measures of

meaning, metapersonal self-construal, mysticism, religiosity, and social desirability offer support

for construct and criterion-related validity. According to both intelligence criteria and current

psychometric standards, findings validate the proposed model and measure of spiritual intelligence.

Future directions are discussed.
