Opis:
The aim of this study (N = 713) was to adapt the Appearance Schemas Inventory–Revised into Polish and evaluate its psychometric properties. The ASI-R is a widely used tool for measuring appearance schemas, but it is currently not available in Polish. The adaptation of the ASI-R has the potential to fill this gap and encourage research in the Polish community. The validation of the scale was conducted on two separate samples of healthy adults. Although the results indicate that the Polish version of the scale, in contrast to the original one, exhibits a one-factor structure, its psychometric properties are robust. The scale demonstrates high internal consistency and sound construct validity, established through correlations with various aspects of psychosocial functioning, along with body image and sociocultural attitudes toward appearance. The scale seems to be gender-invariant and can be utilized in future studies that adopt a cognitive-behavioral approach to appearance schemas.

Opis:
The Generalized Problematic Internet Use Scale (GPIUS2) was developed to operationalize the theoretical cognitive-behavioral model of GPIU.  The aims of the study were to examine the theoretical model of GPIU, analyze the psychometric properties of the GPIUS2 among Polish adolescents, study measurement invariance across gender and method of data collection (offline vs. online). The sample comprised of 1,621 participants (52% men, Mage = 20.3). Some participants completed an online version of the GPIUS2 (n = 707, 73% men, M = 17.9), and others filled in a pencil and paper version (n = 914, 35% men, M = 22.1). Reliability was assessed (Cronbach’s α; McDonald’s ω). The factor structure and nomological, convergent, and discriminant validity were tested. The findings of this study supported the reliability and the factor structure of the GPIUS2. The factor similarity in Polish sample and the original US sample was high (Tucker’s congruence coefficients were range: .99–1.00). The structural relationships between the constructs of the model, convergent and discriminant validity were confirmed. The strong measurement invariance of the model across gender and method of data collection was confirmed. The Polish version of the GPIUS2 is a reliable and valid instrument that can be used for Polish adolescent samples. The scale showed measurement invariance across gender and method of data collection. Furthermore, the results support the cognitive-behavioral model of problematic Internet use in adolescents.

Opis:
In the paper I discuss some premises of “quantum mechanics” with regard to the thesis that the time arrow does (not) exist. In this context I consider above all the famous Einstein-Podolsky-Rosen’s experiment (EPR-experiment). I also indicate Schrödinger’s interpretation of wave function “symmetrical” towards time (nomological isotropy) and the peculiar understanding of the pair particle-antiparticle, assuming that the direction of time can be reversed. Eventually, I discuss the issue of measurement in quantum mechanics with which the existence of time arrow (anisotropy) is often linked. If it comes to the interpretations of quantum mechanics, from the point of which I consider the issues in question, then in principle I limit myself to two: the so-called Copenhagen interpretation and David Bohm’s conception of “hidden parameters.” I arrive at a conclusion that the premises of quantum mechanics that are at issue here cannot be sufficient grounds for a conclusive recognition of the reversibility (non-existence) of time arrow.
