In recent years, psychology has emphasized positive emotions and their recognition and regulation. In preventive psychology, primary prevention is considered the most cost-effective strategy for promoting community mental health (
1). Among positive emotions, happiness is a core component of psychological well-being and has attracted growing attention (
2). It is viewed as a fundamental human need and a determinant of family and societal health, supporting hope, motivation, and progress (
3).
Happiness is a subjective sense of well-being that includes positive emotions and life satisfaction, with low negative affect (
4). It has two dimensions: Affective (pleasure/positive emotions) and cognitive (life satisfaction judgments) (
5).
Many occupations involve chronic stress, which can negatively affect mental health, performance, and attendance (
6). Employee happiness has become a strategic concern for institutions (
7). In hospitals, nurses are a critical workforce due to sustained patient contact (
8). Research in China has shown moderate happiness among nurses (
9,
10), and studies in Iran have reported similar levels (
11,
12).
Given nursing’s high stress, improving nurses’ happiness is important for well-being and care quality (
13). Happiness is associated with better health, self-esteem, self-confidence, and quality of life (
14).
Responsibility may be related to happiness (
15). Higher happiness may strengthen informal networks, communication, and responsibility, potentially improving organizational commitment and attractiveness (
16). Social responsibility is an ethical obligation across individuals, organizations, and governments and may support organizational performance and employee well-being (
17). It reflects readiness to engage with society, uphold trust, and act with integrity. Beal defines social responsibility as commitment to policies and actions that promote societal, environmental, and human development interests alongside economic goals (
18). Responsible behavior is linked to cognitive development, ethical awareness, social consciousness, and interpersonal competence (
19).
With increasing national and global relevance, social responsibility is considered a driving force for societal advancement (
20). Its presence supports ethical and lawful behavior, while its absence may lead to adverse societal consequences (
21). In healthcare institutions, social responsibility can enhance organizational credibility and public trust (
22). Nurses, as frontline providers, must uphold social responsibility through patient safety, ethical conduct, and equitable, high-quality care (
23,
24).
Despite its importance, social responsibility remains underexplored in nursing, particularly in Iran. Few studies have examined its relationship with nurses’ happiness. Given its implications for healthcare delivery and staff well-being, further investigation is warranted.
