Psychometric Properties of a Russian Version of the Comprehensive Scale of Intellectual Humility

Abstract

Background. Intellectual humility (IH) can be defined as an awareness of one's intellectual fallacy that does not threaten the Ego. The Comprehensive Scale of Intellectual Humility (CIHS; Krumrei-Mancuso & Rouse, 2016) measures four aspects of IH: Openness to Revising One’s Viewpoint, Lack of Intellectual Overconfidence, Independence of Intellect and Ego, and Respect for Others’ Viewpoints. Objectives. The purpose of this study was to develop and evaluate psychometric properties of a Russian version of CIHS. Study Participants. The participants were 300 respondents, including 186 women and 144 men aged 18 to 70 years. Methods. The items of CIHS were translated from English to Russian using the back-translation method. We next examined the CIHS factor structure, its internal consistency, and a nomological network of CIHS assessing its correlations with the HEXACO-PI-R, which measures six basic personality traits. Results. The Velicer’s minimum average partial index revealed a four-factor solution turned out to be optimal, which corresponded to our theoretical expectations. Principal component analysis supported a four-component structure suited to the original IH model. CIHS (α = 0.72) and its subscales (0.65 < α < 0.82) showed acceptable internal consistency. The subscales were positively correlated with HEXACO’s Conscientiousness, Agreeableness (vs. Anger), Openness to Experience, and Honesty-Humility, evidencing convergent validity of the test. Conclusions. As a preliminary corollary, the Russian adaptation of CIHS has shown satisfactory psychometric properties, which makes the questionnaire acceptable for research purposes and for further testing its practical implications.
