Reliability and Validity of the Measure of Life Priorities: A Questionnaire Based on the Good Lives Model

This study examined the reliability and validity of the "Measure of Life Priorities" (MLP) which was developed to ascertain a person's Good Lives Model (GLM) goods. The MLP was validated against a number of relevant constructs, and the test-retest reliability of the measure was evaluated. The MLP had acceptable reliability for both Importance (α= .694) and Achievement (α= .733) of the goods. Most items demonstrated moderate test-retest reliability (ICCs from .52 to .74) and an overall trend demonstrating that items focused on Importance appeared more reliable. The implications include broadening the settings in which the GLM can be studied.
