Background:

According to spirituality well-being, ambiguity intolerance, and happiness conceptualizations, this study was purposed to investigate the influences of spiritual well-being and uncertainty tolerance on happiness with regards to the moderating roles of sex in the elderly.

Method:

Participants included 120 elders from Shiraz City, Fars province, Iran. A demographic questionnaire, the Spiritual Well-Being Inventory (SWBI), the Multiple Stimulus Types Ambiguity Tolerance Scale-II (MSTAT-II), and the Oxford Happiness Questionnaire (OHI) were used for data collection.

Results:

Findings showed that spirituality well-being and uncertainty intolerance explain 60% of happiness variation in the elderly. But results rejected the role of sex on the prediction of happiness in the present study.

Conclusion:

This study demonstrates the predictive roles of spiritual well-being and ambiguity tolerance on happiness in the field of gerontology.
