<p>The article presents the results of testing the Uncertainty Response Scale method on a Belarusian sample. The scale includes subscales: Emotional uncertainty, Cognitive uncertainty, and Desire for change. The sample included 425 teenagers from the Republic of Belarus aged 10 to 18 years (average age 14,8 ± 1,4 years, 54,35% female). The Uncertainty Response Scale demonstrated good internal consistency (Cronbach’s alphas for subscales 0.81–0.95; confirmatory factor analysis fit indices GFI = 0.86; CFI = 0.91; RMSEA = 0.069 [0.064; 0.074]; SRMR = 0.0656; CMIN/df = 3.0) and invariance with respect to gender, age group, and country of residence (Republic of Belarus, Russian Federation). The Multidimensional Life Satisfaction Scale was used to test external validity. No differences by gender and age were found. Adolescents with different academic performance differ in their style of coping with uncertainty: successful students are characterized by much higher values of Cognitive uncertainty and Desire for change and lower values of the Emotional uncertainty.</p>
