Happiness refers to individualism and the focus on pleasure and other positive emotions (
1). This feeling comprises three components, namely high-level positive emotion and low-level negative emotion as the emotional aspects of happiness, and satisfaction with life, which involves the cognitive component (
2-
4). Research suggests that feeling of happiness helps to pursue important goals, extends the scope of attention, and improves the well-being and psychological health of individuals (
5). Positive emotions allow people to focus on new stimuli by providing attention flexibility (
4). Research reveals that elevated emotions are associated with improved physical health, which in turn improves psychological health (
6-
9).
Although positive emotions are considered a good phenomenon, experiencing these emotions may cause anxiety (
10). Although the concept of happiness has been well addressed in literature, few studies have answered the question of "When a feeling of happiness experiences heavily, does it can be leads to negative consequences?” (
5). Gilbert et al. found significantly positive correlations between fear of happiness and depression (
11). Joshanloo studied 220 students, and observed significantly negative relationships between fear of happiness and satisfaction with life (
10). Although the emphasis placed on controlling feelings of happiness and on the efforts to live happily appears to be global, it is mostly observed in western individualistic cultures (
1), and evidence suggests that happiness is of a lower value in eastern cultures (
12-
15); for instance, Lindberg showed that East Asian people report a limited capacity for gaining and enhancing pleasure in positive experiences; in fact, these people were more willing to modify or shorten their enjoyable periods compared to Americans (
16). A study on the perception of Taiwanese and American students of happiness found that, unlike the Taiwanese participants, the Americans described happiness as their ultimate and most precious goal in life (
17,
18). “Fear of happiness” does not appear an alienate concept in the Iranian culture; for instance, according to the prevalent “Evil-Eye” belief in Iranian tribes, people who refuse to hide their feelings of happiness and success will soon face failure and inconvenient events (
19). Moreover, culture affects human’s attitudes towards positive experiences, especially happiness. Evidence also suggests that being reluctant to show happiness and even being afraid of happiness are more prevalent in Asian cultures than that in other regions of the world (
20). Examining the cultural validation of the fear of happiness scales is therefore essential.
Some questionnaires have designed to measure fear of happiness. For example, fear of happiness scale includes five items designed by Joshanloo, whose internal consistency was reported to be 88% (
10). The intercultural validity of this scale was confirmed in 14 countries, including Brazil, India and Russia and etc. The single factor construct of this scale was approved and a Cronbach’s alpha of 0.70 - 0.87 was calculated in 13 countries (
20). To assess the formal validity of this scale, the valuers’ group was validated and the Cronbach’s alpha for its internal consistency of 0.90 was reported (
11). This scale was designed to complete the Joshanloo’s scale, and less has examined in comparison to Joshanloo’s scale. To the best of the authors’ knowledge, this scale has never been examined in the Iranian culture. Demonstrating the cross-cultural validity of the scale developed by Gilbert et al. was therefore essential.
