Summary
This study validated the Type C Personality Inventory for cross-cultural research on immunosuppressive emotions in healthy individuals and cancer patients. The inventory demonstrated good reliability and validity, supporting its use in future studies.
Area of Science:
- Psychological Science
- Oncology
- Cross-Cultural Psychology
Background:
- Investigating immunosuppressive behaviors and emotions, termed "Type C," is crucial for understanding psychological factors in health and disease.
- Cross-cultural research is needed to explore the universality and variability of Type C personality traits.
Purpose of the Study:
- To assess the validity and reliability of a Type C Personality Inventory.
- To prepare for cross-cultural studies examining Type C in healthy individuals and cancer patients.
Main Methods:
- The Type C Personality Inventory was administered to a sample of 128 healthy volunteers.
- Reliability was assessed using Cronbach alpha coefficients.
- Validity was evaluated through correlations with standardized psychological tests.
Main Results:
- The inventory demonstrated moderate to high Cronbach alpha coefficients, indicating good internal consistency.
- Acceptable validity was supported by significant correlations between the inventory's subscales and established psychological measures.
Conclusions:
- The Type C Personality Inventory is a reliable and valid instrument for assessing Type C personality traits.
- The findings support the use of this inventory in future cross-cultural research involving diverse populations and clinical groups.

The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life.

Individualist and collectivist cultures emphasize different core values, shaping personality in distinct ways. In individualist cultures, such as those in the United States, England, and Australia, people prioritize independence, competition, and personal achievement. These societies tend to promote self-focused traits, with individuals often reporting higher levels of self-esteem. In contrast, collectivist cultures, commonly found in regions like Asia, Africa, and South America, emphasize...

01:26Self-Esteem and Culture
Self-esteem, a core psychological construct, is intricately shaped by cultural context and varies significantly between collectivist and individualistic societies. In collectivist cultures such as Japan, self-esteem tends to be flexible, context-sensitive, and influenced by relationships. A Japanese student, for instance, may show restraint in formal settings like school but behave more openly among close friends, reflecting the flexible and dynamic nature of self-concept in such...

Correspondence bias, also referred to as the fundamental attribution error, describes the tendency to attribute another person’s behavior to internal characteristics rather than situational influences. This cognitive bias leads individuals to overlook external factors that may be influencing actions, thereby fostering potentially inaccurate assessments of others’ intentions and dispositions.Empirical Evidence for Correspondence BiasResearch has consistently demonstrated the prevalence of...

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...
