The relations of gratitude toward God and dispositional gratitude with well-being and personality were investigated, in an Iranian sample. As expected, gratitude was associated with higher scores on happiness, life satisfaction, psychological well-being, and the Big Five factors of personality. Dispositional gratitude out-predicted religious gratitude in relation with well-being. A second study confirmed the results in a second sample of Iranian Muslims, and in a sample of Polish Christians, providing cross-cultural evidence that the dispositional gratitude is a unique predictor of well-being. Positive links between gratitude and Honesty–Humility provided additional construct validity for these variables, as personality dimensions representing the bases of reciprocal altruism.

The relations among religiousness, subjective well-being (SWB) and the HEXACO (Honesty–Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness) model of personality were studied in a Muslim population. As expected, Extraversion and Honesty-Humility factors were the strongest correlates of SWB and religiosity, respectively. Religiosity also correlated with higher levels of SWB, and explained variance in SWB beyond personality factors, showing that religion is a unique predictor of well-being. Results have been discussed within the religious orientation paradigm, and the HEXACO model of personality structure.

The relationship of religiousness with the HEXACO (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, Openness) model of personality was studied in Iran and the United States. Correlations of personality factors and religiousness were generally similar across the two societies. In both countries, religiousness was associated with higher scores on Honesty-Humility, Extraversion, Agreeableness, and Conscientiousness. The Honesty-Humility factor was one of the strongest correlates of religiousness in both countries. These findings support Saroglou's observation that the main personality characteristics of religiousness are consistent across different religious contexts and personality measures and models.

End-of-life decisions (ELDs) represent a controversial subject, with ethical dilemmas and empirical ambiguities that stand at the intersection of ethics and medicine. In a non-Western population, we examined individual differences in perceiving ELDs that end the life of a patient as acceptable and found that an attitude toward euthanasia (ATE) scale consists of 2 factors representing voluntary and nonvoluntary euthanasia. Also, acceptance of ELDs that end the life of a patient negatively correlated with life satisfaction, honesty–humility, conscientiousness, and intrinsic and extrinsic personal motivation toward religion. These findings provided additional construct validity of the ATE scale.

Background: While the role of some personality traits has been comprehensively explored, scientific study of others, such as patience has been neglected. Psychologists have paid scant attention to patience as a personality trait, character strength or virtue. Objectives: The current study examined the relationship between patience and life satisfaction, mental health, and personality. Materials and Methods: A sample of 252 Iranian college students (129 females and 123 males) completed the 3-factor patience scale, satisfaction with life scale, general health questionnaire, anxiety and depression scales and mini international personality item pool-big five. Results: The three types of patience (interpersonal, life hardship, and daily hassles) were associated with higher levels of life satisfaction and lower levels of depression, anxiety and psychological dysfunction. Patience also showed moderate relationship with the Big-Five factors of personality. After controlling the personality factors, patience managed to explain additional unique variance in life satisfaction and mental health indicators. Conclusions: Patience is a unique predictor of mental well-being. It is suggested that long-term patience is more important for depression and general health, whereas short-term patience is more beneficial for hedonic well-being.
