The TIPI is the recommended 10-item version of the Big Five personality measure (a 5-item FIPI version also exists but has inferior psychometrics). Each of the five Big Five dimensions is measured with two items — one positively and one reverse-scored. Convergence with the 44-item BFI ranged from 0.65 (Openness) to 0.87 (Extraversion). Alpha is intentionally low given two items per dimension — test-retest reliability (0.62–0.77) is the more appropriate reliability indicator. Recommended when survey length prohibits use of the BFI or NEO-PI-R.
7-point Likert (1=strongly disagree to 7=strongly agree); each item is a paired trait descriptor (e.g., 'Extraverted, enthusiastic'); items stem from 'I see myself as:'

(R) = reverse-scored. The FIPI (5-item version) is not a condensed TIPI but a parallel instrument; it includes descriptive elaborations for each item. TIPI is preferred for its superior psychometric properties. Two items per dimension means alpha is an inappropriate reliability metric — test-retest should be reported. Validated against BFI, NEO-PI-R, peer ratings, and observer ratings across samples totalling ~3,500 students.
