On the Measurement of Meaning: Logotherapy's Empirical Contributions to Humanistic Psychology

Meaningful living is a central focus of several humanistic theories and therapies. Measurement of life meaning meets many obstacles, including pragmatic concerns, such as measuring subjective experiences, and theoretical objections often offered by humanistic psychologists. The purpose of this article is to summarize empirical efforts related to logotherapy, a humanistic–existential paradigm, to illustrate the utility of assessment within the larger context of humanistic psychology. An overview of five logotherapeutic measures of meaning is provided. These measures include the Purpose in Life test (PIL), the Life Purpose Questionnaire (LPQ), the Seeking of Noetic Goals test (SONG), the Meaning in Suffering Test (MIST), and the Life Attitude Profile Revised (LAP–R). Directions for use of such measures in future research are also offered.
