Spiritual health; concepts and challenges

One of the four types of health is "spiritual health" for whose evaluation in different individuals and groups as well as examining its relationship with other types of health (physical, mental and social) various instruments have been presented. Despite conducting a considerable number of researches, still a large number of problems such as ambiguity in the definition of spiritual health, lack of consensus about basic concepts related to the problems, absence of specifying borders of spiritual health and spirituality, lack of suitable instruments for evaluating spiritual health (lack of appropriate questionnaires, evaluating other fields of health instead of spiritual health, lack of acceptable validity and reliability of some evaluation instruments, …), and using small and non‐generalized samples are faced. Considering the nature of the problem, it seems that conducting sound scientific researches based on an intact source of spirituality is one of the measures which may play a role in resolving the mentioned problems.
