The article proposes the results of a study of psychometric properties of The Student Workaholism Questionnaire developed in Ukrainian and studied on student sample (N = 191). A review of current studies regarding the structure and measurement of workaholism is proposed. The internal consistency, concurrent validity, discriminatory power, internal structure are studied, the constructive validity of the questionnaire is substantiated. The results indicate good internal consistency of the questionnaire (Cronbah's α = 0.88), significant-high correlation of the questionnaire with the Dutch Work Addiction Scale (Pearson's r = 0.55, 0.59 for different scales, P < 0.01), excellent discriminatory power of scores (Ferguson's δ = 0.99). Based on the exploratory factor analysis, the six-factor structure of students' workaholism is proposed. It includes (1) the pressure of the need to perform tasks (2) obsession with work; (3) health neglect; (4) selfexploitation; (5) intrinsic learning motivation; (6) perfectionism. This structure appears to be novel, thus, requires future confirmatory studies across different samples. Limitations and prospects of the research are discussed.
