Primary use / Purpose:
Despite the importance of 'meaning in life' in the field of humanistic counseling it has often been measured poorly. To overcome this Steger, Frazier, Oishi and Kaler (2006) designed and validated the 'meaning in life questionnaire' (MLQ). Three studies have now demonstrated that the scale has high internal consistency, temporal stability, factor structure, and strong validity. Furthermore, the MLQ has several advantages over existing scales such as better discriminant validity, brevity, and the ability to measure the search -rather than merely the attainment- of meaning in life.
The psychometric properties of the 'meaning in life questionnaire' (MLQ) are extensively discussed by the authors in Steger, Frazier, Oishi and Kaler (2006
