Psychometrics of Art: Validation of RizbA, a quantitative rating instrument for pictorial expression
Although art has been subject to research for some time, in quantitative research the artwork itself received little attention. This is probably in part due to the lack of objective, reliable and validated measurements in this field. The rating instrument for two-dimensional pictorial works (RizbA) fills this gap by providing a tool for formal picture analysis. It covers aspects such as shaping, spatiality, representation, colour intensity, pictorial elements and composition.
The presented study validates the questionnaire on 294 images (drawings, paintings, collages and mixed techniques in between) created by 147 non-artists. In a randomized online test-retest study the material was rated by 880 (T1) and 475 (T2) experts using RizbA. Statistical quality criteria, principal component analysis and indices of factor similarity were computed.
The overall test's capacity of differentiation yields a partial eta-squared of .28 (T1) and .33 (T2). Test-retest reliability is .93. PCA reveals an eight-factors solution. Tucker's coefficients of congruence range between |0.82| and |1.00|. Intraclass correlation coefficients are .81 (T1) and .84 (T2).
Results indicate generalizability to amateurs' works. This methodical tool is especially of interest in art therapy research. As the first reliable and validated tool for picture analysis allowing inferential statistics, RizbA enables a more detailed examination of art and its correlates, such as differential or clinical constructs. For instance, art therapy's inherent hypothesis – the artwork being connected to its creator's inner representations – could be empirically tested.
The questionnaire is freely available in terms of open methodology and can be applied by researchers as well as art practitioners.
