Abstract
In some circumstances rule-governed behavior, a behavior that is governed by verbal rules instead of environmental consequences, may be beneficial for human beings. At the same time, rigid rule following is associated with psychopathology. Thus measurement of rule-governed behavior may be of special use in a clinical setting. The aim of this paper is to assess the psychometric properties of Polish adaptations of three questionnaires measuring generalized tendency to engage in various types of rule-governed behaviors: Generalized Pliance Questionnaire (GPQ), Generalized Self-Pliance Questionnaire (GSPQ), Generalized Tracking Questionnaire (GTQ). A forward-backward method was used for translation. Data was collected from two samples: general population (N = 669) and university students (N = 451). To measure the validity of the adapted scales the participants filled in a set of self-assessed questionnaires: Satisfaction with Life Scale (SWLS), Depression, Anxiety, and Stress Scale- 21 (DASS-21), General Self-Efficacy Scale (GSES), Acceptance and Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), Valuing Questionnaire (VQ) and Rumination-Reflection Questionnaire (RRQ). The exploratory and confirmatory analyses confirmed the unidimensional structure of each of the adapted scales. All of those scales presented good reliability (internal consistency measured with Cronbach Alpha) and item-total correlations. The Polish versions of questionnaires presented significant correlations in the expected directions with relevant psychological variables in line with the original studies. The measurement occurred invariant across both samples as well as gender. The results provide evidence that Polish versions of GPQ, GSPQ and GTQ present sufficient validity and reliability to be used in the Polish-speaking population.
