Discrepancy between self-report and other-report assessment via psychological questionnaire
VEDRALOVÁ, Aneta
Bachelor thesis deals with asymmerty in mutual evaluation between research partners. The theoretical part summarizes previous findings from a research of specific differences between questionnairy self-assessment and assessment by other person and presents possible reasons for this discrepancy, among which we can find for example the effect of social desirability, the closeness of the relationship between the assessed or the limits of introspection. Another part of the theoretical framework is devoted to the description of used test methods. The empirical part describes the methodological framework and analysis of data gathered from the research project CPACT (Computational Psycholinguistic Analysis of the Czech Text, GA CR 16-19087S). The goal of the research part is to find out by using relevant statistical methods whether there is a statistically significant difference between self-report and other-report, based on the comparison of results in selected BFI 44, STAI X-2, IAS-R and PSSI scales. Another goal is to find out whether there is a correlation between the different assessments, meaning the discovered discrepancy, and the degree of closeness in research partners' relationship. N=242 probands were tested, which means n=121 research pairs. The results show that there are significant differences between self-assessment and assessment by other person in all examined dimensions, except for the openness towards experience in BFI 44. The correlation between discrepancy in assessment between partners and the degree of closeness of their relationship, measured by the Questionnaire of Relationship Closeness, was confirmed only in extravertion in BFI 44, in assure-dominant scale in IAS-R and in anxiety as a personality trait in STAI X-2. However, the dependencies found by Spearman's correlation coefficient are too weak to draw any relevant conclusions.
