Measuring the unmeasurable: Psychometric tools for Existential Concerns
Key psychometric instruments for measuring existential concerns: meaning in life, existential isolation, and existential anxiety.
Michael F. Steger et al. (2006)
New questionnaire MLQ to measure meaning in life through Presence and Search domains
The authors created Meaning in Life Questionnaire in a positive context (Frankl's construction of meaning concept). The scale has 2 subscales (Presence and Search), 5 questions each. The tool is heavily used by other researchers and has many adaptations to different languages. Worth using if one needs to assess meaning in life or existential concern of meaninglessness.
creating and validating a new scale
basic existential notions (meaning in life); Frankl + Yalom
A nice replacement of the old PIL scale that can assess the existential concern of meaninglessness, though some questions have arguable discriminant validity. To use!
