All questionnaires, regardless of what they measure, must demonstrate good performance with regard to psychometric properties. Psychometrics is a branch of survey research that has developed methods how to quantify errors in measurement because no matter how well is the questionnaire prepared, observed data bears except of desired true data also measurement errors. You should distinguish notion psychometrics from psychometrics used in sociological practice. There is no Slovak equivalent for psychometrics (as a branch of survey research) at the moment, although term psychometrics is common abroad and comprehended correctly. But we can also say we are introducing methodological requirements for data collected through the questionnaire surveys that should be satisfied prior to any statistical manipulation. Rehák (1998) noticed the quality of data determinate the quality of results. In general, questionnaires collecting research data should satisfy requirements of validity, reliability and feasibility. Criteria and standards in psychometrics are not defined as strict rules, but rather as ranges within you would expect certain indicators to fall if the questionnaire is operating correctly. Also the strict limit showing which and how many tests must be used to proof the quality of questionnaire is missing. According to the most of reviewed literature authors use the same set of tests that vary only in number of tests according to which psychometrics areas were tested. Methodology, how to test your quality of data collected through the questionnaire survey, is demonstrated on empirical Slovak data achieved through the Multi-country Survey Study (MCSS) questionnaire.

The reliability and factor structure of the General Health Questionnaire-12 (GHQ-12) and the Rosenberg Self-Esteem scale (RSE) were evaluated in samples of Hungarian and Slovak early adolescents. The principal component analyses support the two-factor solution for GHQ-12 with subscales 'depression/anxiety' and 'social dysfunction'. Similarly, the RSE appears to be an instrument with a two-factor structure with subscales 'negative self-esteem' and 'positive self-esteem' in both samples. Reliability analyses of GHQ-12 and RSE total scales show satisfactory results, although the reliability figures of some components is lower. The factor structure of RSE component 'negative self-esteem' is less clear. Researchers need to be aware of the potential problems surrounding the negative item wording and make every effort to ensure that negatively-worded items are carefully constructed and easily interpreted by the population of early adolescents.

The aim of the paper is to describe the process of development and evaluation of a newly designed spatial ability test. It consists of two consecutive studies. In Study I (N = 267) we proposed 35 items equally divided into five subsets. The items were designed with respect to theoretically described spatial ability dimensions (spatial perception, orientation, visualization, relations, and mental rotation). Even though the five factor structural model fitted the data reasonably well, on the principle of parsimony we agreed on un-dimensional model. Items with the best parameters (n = 25) were considered as the final version of the test. In Study II (N = 124) we verified that there is no significant impact of the administration media (paper/pencil vs. computer-based). The test-retest stability with a six-week interval was acceptable (r = 0.796), and so was the internal consistency (Cronbach’s α = 0.752). We have found a modest correlation (r = 0.470) with the Spatial Reasoning subtest of the Intelligence Structure Test.

Research on the psychological characteristics of the image of God is one of the dynamically developing areas in psychology of religion. The aim of the paper is to present certain information on God Image Scales – a psychometric instrument which identifies psychological characteristics of the image of God in six dimensions: Presence, Challenge, Acceptance, Benevolence, Influence, and Providence. The author of the questionnaire, Richard Lawrence, based this instrument on two particular theories: the Attachment theory and the Object relations theory, with both applied to religion. In the present case the instrument primarily focuses on an experiential image of God as opposed to a rationally learned image of God. The paper also presents the Slovak adaptation of the questionnaire and explains how the Slovak version was developed using item analysis of three independent research samples. An exact translation of the original version does not guarantee the same psychometric characteristics as the original version. In conclusion, the advantages and disadvantages of using the instrument are discussed from the point of view of psychology and theology as well. The Slovak adaptation of the God Image Scales may contribute to research studies, clinical practice and pastoral work as well.

Internal and external motivation to respond without prejudice scale (IEMS) provides a self-report tool sensitive to individual tendencies to control implicit and explicit prejudice without directly inquiring about attitudes toward an outgroup. The current study verified the scale’s psychometric properties and construct validity on a Slovak sample. In line with the predictions, the principal component analysis suggested, and confirmatory factor analysis validated the presence of two uncorrelated factors of internal and external motivation. Additionally, while internal motivation was positively associated with adherence to egalitarianism and negatively with authoritarianism, external motivation did not demonstrate any of these relationships. Furthermore, only external motivation was found to be positively related to expressive self-control that parallels propositions claiming greater self-regulatory demands when egalitarian norms are followed to avoid social disapproval. Finally, both factors were positively correlated with concerns from appearing prejudiced, although internal motivation in a significantly greater degree, reflecting larger dependency on self-oriented concerns. With appropriate values of internal consistency for both factors, the IEMS scale provides a reliable self-report measure that might be used for systematic control of individual differences in the research of social cognition in intergroup context.
