Russian-Language Adaptation of the Questionnaire D. Webster and A. Kruglyanski “The Need for Cognitive Closure”

The article presents the results of the Russian-language adaptation of the Need for Closure Scale by A. Kruglyansky and D. Webster, which in its original English version includes 5 scales, 42 questions and additional 5 questions of the “Lie scale”. The scales of the questionnaire are: “The need for order” (10), “The need for predictability” (8), “Decisiveness” (7), “Avoidance of ambiguity” (9) and “Closed-mindedness” (8). For adapting the questionnaire, the following procedures and statistical methods were applied: double-blind forward and backward translation of the questionnaire; checking the discrimination of Ferguson’s ; consistency of Cronbach’s and McDonald’s for the entire test and individual test scales, confirmatory factor analysis (CFA) by the method of maximum likelihood, testing of retest reliability, gender differences and external validity. The study involved 643 subjects at the factorization stage and 114 at the external validity stage. The obtained results for the Russian-language scales are: "the need for order" Cronbach’s = 0.81. "the need for predictability" Cronbach’s = .75 "decisiveness" Cronbach’s = .74. "avoidance of ambiguity" Cronbach’s = .65. "closedmindedness" Cronbach’s = .53. Checking the questionnaire (5-factor version, 38 questions) with the Structural Equation Modelling (SEM), indicators were obtained within the norm: 2/df = 4.08, SRMR = .078, RMSEA = .07, however, the CFI and TLI parameters do not correspond to the required norms (CFI = .67, TLI = .647 — below normal). In the test-retest the correlation obtained r =.72, with p .001. Based on the data obtained, a conclusion is made about the correspondence of the five-factor model of the questionnaire of 38 questions to foreign analogues in terms of the degree of consistency.
