Procedures to examine the causes and consequences of meaning

Measuring meaning

Steger, Frazier, Oishi, and Kaler's Meaning in Life Questionnaire separates the presence of meaning from the search for it, and it is among the most commonly used tools. Researchers increasingly distinguish between several components of the construct.

• Coherence: life makes sense
• Purpose: having valued long-term aims
• Significance: feeling that one's life matters

Common designs

Cross-sectional surveys show which variables go together. Daily diary studies follow fluctuations within a person, and longitudinal studies look at whether meaning at one time is linked to outcomes at another. Experiments may induce a mood or a sense of belonging or threat, then measure meaning. King, Hicks, Krull, and Del Gaiso reported that positive mood predicted higher ratings of meaning, raising the possibility that mood colors these judgments.

Limits on inference

Self-report items may overlap with measures of wellbeing, making relationships between them partly circular. Brief laboratory manipulations can produce shifts in responses without altering how people really view their lives. Heintzelman and King argued that most people rate their lives as fairly meaningful, which leaves less room for scores to rise. Long-term randomized studies are scarce, and associations between meaning and later health may reflect third variables such as income, social ties, and prior illness. Careful designs combine repeated measurement with attention to such confounds.
