Instruments Methods: The current study is descriptive-correlation research (structural equations). The statistical population consisted of all the prisoners of the Iran-Iraq war in Tehran in 2021-2022, of which 178 prisoners of war entered the research through non-random and voluntary sampling. Data were collected using Oxford Happiness Questionnaire, Depression, Anxiety and Stress Scale, Cognitive Flexibility Inventory, and Spiritual Intelligence Scale. Findings: Anxiety indirectly affects happiness through the mediator variable of spiritual intelligence, with a standardized coefficient of -0.033 (p 0.05). Depression indirectly affects happiness through the mediator variable of spiritual intelligence, with a standardized coefficient of -0.040 (p 0.01). Cognitive flexibility indirectly affects happiness through the mediator variable of spiritual intelligence, with a standardized coefficient of 0.133 (p 0.05). Conclusion: Happiness is predicted based on anxiety, depression and cognitive flexibility with the mediation of spiritual intelligence in prisoners of war.
