The definition of spirituality has broadened, leading to measurement tools that include general well-being. This results in a tautological link between spirituality and mental health, questioning its academic validity.
Area of Science:
- Psychology
- Medical Research
- Sociology
Background:
- Spirituality is increasingly studied for its links to mental and physical health.
- The definition of spirituality has evolved from a purely religious concept to a broader spectrum including secular well-being.
- Current measurement tools for spirituality often incorporate measures of positive character traits and mental health.
Purpose of the Study:
- To critically evaluate the current measurement and definition of spirituality in academic research.
- To address the issue of conceptual contamination in spirituality assessments.
- To determine the validity of reported associations between spirituality and health outcomes.
Main Methods:
- Analysis of the conceptual evolution of spirituality.
- Review of instruments used to measure spirituality.
- Critical assessment of research methodologies linking spirituality to health.
Main Results:
- Spirituality measures are often "contaminated" with items assessing optimism, gratitude, purpose in life, and general well-being.
- Studies report a correlation between spirituality (as measured) and good mental health.
- These associations are considered meaningless and tautological due to the overlap in constructs.
Conclusions:
- Current definitions and measurements of spirituality in research are problematic.
- Spirituality should be redefined and measured as a unique construct, distinct from general mental health.
- Alternatively, the use of spirituality as a construct in academic research should be reconsidered if it cannot be uniquely defined and measured.
