The Prediction of Quality of Life - based on Personality Traits and Spiritual Intelligence in the Elderly

Introduction: Considering the increasing trend of the elderly population in Iran, attention paid to this critical phase, both socially and psychologically, is essential in improving their quality of life. The present study aimed to investigate prediction of quality of life - based on personality traits and spiritual intelligence in the elderly.   Methods: This correlational study  carried out on older adults in Tehran who lived in nursing homes in 2020 and 182 of them were selected by convenience sampling. The NEO Personality Inventory (NEO-PI), The Spiritual Intelligence Self-Report Inventory (SISRI-24) and Leiden-Padua Questionnaire (LEIPAD questionnaire) were used for data collection. Descriptive statistics (mean, standard deviation) and inferential statistics (correlation and stepwise regression analysis) were used for data analysis. The correlation matrix and stepwise regression were used to predict the quality of life scores based on personality and spiritual intelligence.   Results: There was a significant relationship between personality traits with spiritual intelligence and quality of life (r: 0.361, p < 0.05). Also, there was a significant relationship between spiritual intelligence and quality of life (p < 0.05). Personality traits of neuroticism, extraversion, and spiritual intelligence could predict a total of 38.5% of the variance in quality of life (p < 0.05).   Conclusion: The quality of life has a significant relationship with both spiritual intelligence and personality traits, so, spiritual intelligence and personality components can predict the quality of life in the elderly.
