Abstract. The study verifies the psychometric properties of the Slovak version of the Self-Compassion and Self-Criticism Scales (SCCS) using item response theory, factor analysis, and scale validity. The survey sample was collected by convenience sampling and consisted of 514 participants (27% men and 73% women) with a mean age of 26.16 years (SD = 8.32). A two-dimensional structure of the scale was not confirmed. The Self-Criticism subscale of the SCCS remained the same as in the original study, and the Self-Compassion subscale of the SCCS was divided into the subscales Self-Compassion (compassionate reaction to self) and Self-Reassurance (reassuring and soothing reactions to self). The Slovak translation of the SCCS seems to be a reliable instrument to measure the level of self-compassion and self-criticism. The validity of the SCCS should be further explored by linking the scale results to directly observable outcome measures as there are significant but very weak correlations with other related scales. This could be due to differences between situational and trait self-compassion and self-criticism.

The current research developed ultra-brief (SSOSH-3) and revised (SSOSH-7) versions of the Self-Stigma of Seeking Help scale. Item response theory was used to examine the amount of information each item provided across the latent variable scale and test whether items functioned differently across women and men. In a sample of 857 community adults, results supported removal of three reverse-scored items to create the SSOSH-7. The three most informative items were retained to create the SSOSH-3. Differential item functioning testing supported the use of both versions across women and men. Results replicated in an undergraduate student sample ( n = 661). In both samples, the SSOSH-3 (αs = .82-.87) and SSOSH-7 (αs = .87-.89) demonstrated evidence of internal consistency. The SSOSH-3 ( rs ≥ .89) and SSOSH-7 ( rs ≥ .97) were highly correlated with the original SSOSH across samples and demonstrated significant correlations with help-seeking constructs and in similar magnitude to the original SSOSH.

The human ability for self-consciousness—the capacity to reflect on oneself and to think about one’s thoughts, experiences, and actions—is central to understanding personality and motivation. The present research examined the psychometric properties of the Self-reflection and Insight Scale (SRIS), a prominent self-report scale for measuring individual differences in private self-consciousness. Using tools from Rasch and item response theory models, the SRIS was evaluated using responses from a large sample of young adults (n = 1192). The SRIS had many strengths, including essentially zero gender-based differential item functioning (DIF), but a cluster of poor performing items was identified based on item misfit, high local dependence, and low item difficulty and discrimination. Based on the IRT analyses, a concise 12-item scale, evenly balanced between self-reflection and insight, was crafted. The short SRIS showed strong dimensionality, reliability, item fit, and local independence as well as essentially no gender DIF. Taken together, the many psychometric strengths of the SRIS support its popularity, and the short form will be useful for research and applied contexts where an efficient, concise version is needed.

Item Response Theory Analysis

The Self-Monitoring Scale (SMS) was investigated utilizing item response theory (IRT). First, IRT models that constrained each of the subscale items to have equal discrimination were fitted to the three subscales of the SMS (Acting, Extraversion, and Other-Directedness). These models were then contrasted with separate models that allowed the discriminations to be estimated freely. For all three subscales, model comparison tests of significance indicated that the unconstrained models were a better fit. Thus, the items of each subscale are differentially related to their respective underlying construct. Implications and recommendations are offered for future psychometric development and implementation of the SMS.

The Mean

Personal self-activation inventory that measures a psychological construct reflecting person’s internal voluntary activity is considered in the article. The inventory includes three components (scales): independence, physical activation and psychological activation. In the framework of the Item Response Theory (IRT), the model of graded responses was applied. It is shown that all questions of the inventory have the discriminability not lower than moderate. The graphs of the information function for each scale indicate that the measurements of the self-activation components are fairly accurate in the range from low values to values significantly higher than the mean, and only the highest values (exceeding the mean by two standard deviations or more) are not measured accurately. A moderate positive correlation between self-activation and the average grade can serve as verification of the inventory criterion validity. Discriminant validity estimation, which was carried out by calculating correlations with other similar constructs (self-control, personal dynamism, hardiness), showed that hardiness is the most similar to self-activation construct. Incremental validity estimation has shown that when self-activation is added to the prediction model of performance based on personal resources, the variance explained is increased much more than by adding hardiness. This indicates that the self-activation construct has some incremental validity and reflects a psychological reality that is different from the construct of hardiness.
