VALIDATION OF A QUESTIONNAIRE TEST FOR DETERMINING THE PSYCHOLOGICAL PROPERTIES OF INDEPENDENT VOLITIONAL QUALITIES OF A PERSON
We propose a new tool for determining the strength of volitional qualities of a person - a questionnaire test based on the identification of the psychological properties of seven independent volitional qualities: endurance, initiative, perseverance, self-discipline, determination, independence, and courage. Each of them gives rise to a family of 5 elements necessary and sufficient for constructing a metric scale for assessing the strength of manifestation of this volitional quality. A psychometric justification of the method containing the calculation of its validity and reliability is given. Validation includes content and concurrent aspects of validity. A calculation of retest reliability of the entire test and its individual scales is performed. The scope and feasibility of the proposed test is considered. The questionnaire test is a psychometrically valid tool and can be used in scientific and practical work of a psychologist provided that statistical age standards of application of the questionnaire are developed.
