The Tetreau-Trahan Visual Interest Test (TTVIT) was constructed to counteract the influence of verbal and cognitive factors in the measurement of vocational interests. Two forms were developed--a pictorial test based on color slides of various occupations, as well as a verbal form to be used in comparative studies with samples of persons from different linguistic, cultural, and socioeconomic backgrounds. Item analyses and factorial studies show that the TTVIT is a reliable nonverbal test (alpha coefficients of .82 to .95) yielding scores on scales corresponding to Holland's interests and personality typology. It is now standardized for the high school and college populations of Quebec and Brazil. Given its 20-minute administration time, the possibility of immediately self-scoring and interpreting the responses within an empirically based theoretical framework, and the nonverbal nature of the items which facilitate the prompting of an emotional response, the TTVIT is a practical instrument as well as a tool of cross-cultural interest research allowing for direct comparisons from the same stimuli.
