Development and psychometric characteristics of the questionnaire of constructive and destructive manifestations of subjectivity

The research presents development and psychometric characteristics of the questionnaire of constructive and destructive manifestations of subjectivity. The main components of the subject and subjectivity, following A.V. Brushlinsky, are considered to be activity, autonomy, and integrity. Subjectivity is viewed from two perspectives: external and internal. The questionnaire measures the following properties of subjectivity, manifesting in both constructive and/or destructive forms: Social Activity (constructive and destructive), Mental Activity (constructive and destructive), Coherence (constructive and destructive), Independence (constructive and destructive), Harmonious Interpersonal Relationships (constructive and destructive), and Integration of Subject Properties (constructive and destructive). The study sample consisted of 369 respondents aged 14 to 76 years (M = 21.40, SD = 8.47), including 231 females, 131 males, and 7 individuals who did not specify their age and sex. Several alternative confirmatory models were constructed (hierarchical, bifactor, single-factor, correlating, and non-correlating factors), with the correlating model yielding the best results. These results confirm the construct validity of the questionnaire at an acceptable level.  Internal discriminant and convergent validity, external convergent validity (the questionnaire was compared with methods for measuring subjectivity and aggressiveness), internal consistency reliability, and discrimination of the scales were all evaluated; all of them indicated that the questionnaire was of sufficient psychometric quality. The findings indicated that the questionnaire demonstrates sufficient psychometric quality, supporting its use in both scientific research and psychological practice.
