The purpose of this article is to present the impact of the results of a questionnaire research on the formal aspects of the scales: negative numeric values, zero-start point, kind of labels and length of numeric scale. First research shown, that change of numeric value from positive to negative, without changing the length, drives to crystallization of answers. The middle neutral point „no opinion” is chosen more rarely, than options, which are placed to the right from the midpoint. Answer options placed to the left from midpoint, were chosen most often. In case of „positive” scales, with zero-start point and one-start point, changes of labels do not differentiate the results. In case of „negative” scale, labels, which describe only the end points of scale, will cause left side shift of the results as against to results obtained by „every point” labels. Second research was conducted to verify if the results given in first study are characteristic only to our questionnaire or if they are more versatile. The deeper exploration of the given result was made on NEO-FFI questionnaire. In general, effects were confirmed. In this article, results are also analyzed in methodological and ethical context.
