Development and validation of Chinese form Short Dark Tetrad (C-SD4)

Area of Science:

• Psychology
• Personality Science
• Cross-Cultural Psychology

Background:

• The Dark Tetrad (narcissism, Machiavellianism, psychopathy, sadism) may exhibit cultural variations.
• Existing measures may not adequately capture these traits across diverse cultural contexts.
• The Short Dark Tetrad (SD4) is a brief measure of these traits.

Purpose of the Study:

• To develop and validate a Chinese version of the Short Dark Tetrad (C-SD4) scale.
• To ensure the C-SD4 accurately measures the Dark Tetrad constructs in a Chinese sample.
• To provide a culturally adapted instrument for psychological research.

Main Methods:

• Cross-validation across four studies with a large sample (N=3181).
• Item pool adjustment, scale trimming to a 28-item version, and correlation with Big-5 personality traits.
• Examination of internal structure, measurement invariance, criterion validity, and test-retest reliability.

Main Results:

• The 28-item C-SD4 demonstrated strong reliability and validity.
• Measurement invariance was established across relevant subgroups.
• The C-SD4 showed expected correlations with established personality measures.

Conclusions:

• The C-SD4 is a reliable and valid instrument for assessing the Dark Tetrad in Chinese participants.
• This validated scale can facilitate cross-cultural research on narcissism, Machiavellianism, psychopathy, and sadism.
• The C-SD4 addresses the need for culturally sensitive psychological assessment tools.
