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:
This article is a comparative analysis of Marina Carr’s Ariel (2002) and John Millington Synge’s Riders to the Sea. The main research context comes from common critical treatments of Carr’s oeuvre within the scope of Synge’s influences. The plays discussed in this essay have not been subject to comparative studies before (to the best of the author’s knowledge). The main argument consists in examining the loci of invariance and their transformations with reference to themes, characters’ roles, and their relationships, which will be compared in terms of notions of necessity, generational suffering, reliance on the worldly, and death in the unknown realm, partly treated within existentialism.
Celem artykułu jest dokonanie analizy sztuki Ariel Mariny Carr i Riders to the Sea Johna Millingtona Synge’a. Twórczość Carr często traktowana jest jako kontynuacja dramaturgii Synge’a i utwory tej irlandzkiej dramatopisarki są analizowane w odniesieniu do dramatów Synge’a. Porównanie Ariel i Riders to the Sea wydaje się jednak tematem, który wciąż warto podejmować i wykazywać aspekty niezmienności i ich transformacji. Omówione porównania dotyczą takich motywów, jak: konieczność, pokoleniowe cierpienie, poleganie na doczesności oraz śmierć w nieznanej przestrzeni. Zostaną one częściowo potraktowane w swoim ogólnym odniesieniu do egzystencjalizmu.

Opis:
This study aimed to determine the validity and reliability of the Polish version of the New General Self-Efficacy Scale (NGSE). In four different samples (N = 1,837), adult respondents completed the Polish version of NGSE (NGSEpl) in combination with questionnaires assessing personality, motivation, and behavioral tendencies. Confirmatory factor analysis demonstrated a good fit for the one-factor structure. Cronbach's alpha was above .87 in all samples, and the stability of the scale was .68. Measurement invariance of NGSEpl calculated for different age groups confirmed that the scale measures the same construct in both samples. NGSEpl scores were positively related to the frequency of active coping strategies, mastery-goal orientation, and Big Five model traits and negatively to passive coping strategies. Results supported the reliability, stability, and validity of the NGSEpl.
Celem niniejszego badania było określenie trafności i rzetelności polskiej wersji Nowej Skali Uogólnionego Poczucia Własnej Skuteczności (NGSE). W czterech różnych próbach (N = 1,837) dorośli respondenci wypełnili polską wersję NGSE (NGSEpl) w połączeniu z kwestionariuszami mierzącymi osobowość, motywację i tendencje behawioralne. Konfirmacyjna analiza czynnikowa wykazała dobre dopasowanie struktury jednoczynnikowej do danych. Współczynnik alfa Cronbacha wyniósł powyżej .87 we wszystkich próbach, a stabilność skali wyniosła .68. Niezmienność pomiarowa NGSEpl obliczona dla różnych grup wiekowych potwierdziła, że skala mierzy ten sam konstrukt w obu próbach. Wyniki NGSEpl były dodatnio powiązane z częstością korzystania z aktywnych strategii radzenia sobie, motywacją mistrzostwa, wszystkimi cechami modelu Wielkiej Piątki, a ujemnie z pasywnymi strategiami radzenia sobie. Wyniki uzyskanych analiz potwierdziły zatem rzetelność, stabilność i trafność NGSEpl.

Opis:
Objectives The COVID-19 outbreak is an example of a crisis that triggered an increase in generalized anxiety disorder. The study aims to validate the Polish version of the Generalized Anxiety Disorder 7-item scale (GAD-7) by Spitzer et al. among a non-clinical sample of employees and examine the invariance depending on the gender and age of working adults. Material and Methods For assessing factor structure of the Polish version of the GAD-7, the data were collected from a sample of 821 adults employed in 4 economic sectors (health care, education, IT, public administration) during the initial phase of the COVID-19 pandemic in Poland (April 10–May 24, 2020). Due to differences in the severity of GAD symptoms across gender and age groups, the measurement invariance in these groups was tested. Results The results of a series of confirmatory factor analyses confirmed the unidimensionality of the GAD-7. The values of the composite reliability index and Cronbach’s α showed that it is a reliable tool. The GAD levels demonstrated strong relationships with professional burnout, psychological distress, and psychological complaints. These relationships were stronger than the relationships between these factors and job satisfaction. Construct, metric and scalar invariance across gender and age groups were documented. Women experienced more severe symptoms of generalized anxiety disorder than men. Generalized anxiety disorder affected 28% of respondents. Conclusions This study contributes evidence of the validation of the GAD among employees and also confirms the invariance depending on gender and age. The Polish version of the GAD-7 has good psychometric properties in a group of professionals and can be recommended for research and to be used in an occupational medicine practice, especially during crisis periods associated with the risk of developing a generalized anxiety disorder.

Opis:
This study aims to conduct an Urdu translation and a validation of the ISBF Stress Management Skills Scale in two distinct phases. The first phase includes the forward-back translation method for ISBF. The second phase includes cross validation and the establishment of psychometric properties for the ISBF scale. A sample of 500 adults working in health care was taken from different hospitals and dispensaries. The first phase of the study includes the forward-back translation method. The second phase includes exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with invariance measurement. The total reliability of the scale is reported to be .812. EFA revealed a two-factor structure for ISBF scale, with configural, metric and scalar invariance across males and females, and comparable latent mean scores for males and females. CFA showed goodness-of fit indices for the two factors. The scale showed good internal consistency values. The model fit value includes the value for the goodness of fit index, which was .979, for the adjusted goodness-of fit index: .961, for the comparative fit index: .993, for the incremental fit index: .993, and for the root mean square error of approximation (RMSEA) value: .033. Good values of composite reliability and convergent validity were measured for both dimensions of the scale. The scale shows that this diagnostic tool can help to assess the skills used to manage stress. For criterion validity, the coping Inventory for Stressful Situations (CISS-21) was used, which showed positive correlations. The subscale of stress management was taken from the Health Promoting Life Style Profile II (HPLP-II), which also showed positive correlations. Significant mean differences were found between scores of healthcare workers with stress management skills and with those without stress management skills. The group of mean differences indicated the females have greater stress management skills as compared to men. The Urdu translated and validated instrument will be helpful in understanding behavior in healthcare settings.

Opis:
In microgrid distribution generation (DG) sources are integrated parallelly for the economic and efficient operation of a power system. This integration of DG sources may cause many challenges in a microgrid. The islanding condition is termed a condition in which the DG sources in the microgrid continue to power the load even when the grid is cut off. This islanding situation must be identified as soon as possible to avoid the collapse of the microgrid. This work presents the hybrid islanding detection technique. This technique consists of both active and parametric estimation methods such as slip mode shift frequency (SMS) and exact signal parametric rotational invariance technique (ESPRIT), respectively. This technique will easily distinguish between islanding and non-islanding events even under very low power perturbations. The proposed method also has no power quality impact. The proposed method is tested with UL741 standard test conditions.

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 this paper we extend the method of obtaining symmetries of ordinary differential equations to first order non-homogeneous neutral differential equations with variable coefficients. The existing method for delay differential equations uses a Lie-Bäcklund operator and an Invariant Manifold Theorem to define the operators which are used to obtain the infinitesimal generators of the Lie group. In this paper, we adopt a different approach and use Taylor’s theorem to obtain a Lie type invariance condition and the determining equations for a neutral differential equation. We then split this equation in a manner similar to that of ordinary differential equations to obtain an over-determined system of partial differential equations. These equations are then solved to obtain corresponding infinitesimals, and hence desired equivalent symmetries. We then obtain the symmetry algebra admitted by this neutral differential equation.

Opis:
If the action S= ∫_(t_1)^(t_2)▒〖L(q,〗 (q,) ̇t) dt is invariant under the infinitesimal transformation t ̃=t+ε τ(q,t), q ̃_r= q_r+ε ξ_r (q,t),r=1,… ,n, with ε=constant ≪1, then the Noether’s theorem permits to construct the corresponding conserved quantity. The Lanczos approach employs to ε= q_(n+1) as a new degree of freedom, thus the Euler-Lagrange equation for this new variable gives the Noether’s constant of motion. Torres del Castillo and Rubalcava-García showed that each variational symmetry implies the existence of an ignorable coordinate; here we apply the Lanczos approach to the Noether’s theorem to motivate the principal relations of these authors. The Maxwell equations without sources are invariant under duality rotations, then we show that this invariance implies, via the Noether’s theorem, the continuity equation for the electromagnetic energy. Besides, we demonstrate that if we know one solution of p(x)y''+q(x)y'+r(x)y=0, then this Lanczos technique allows obtain the other solution of this homogeneous linear differential equation.

This study aims to measure the latent mean difference in perfectionism and marital satisfaction by counseling help-seeking attitudes. The respondents were 327 married graduate students from a research university in Malaysia. An online self-administered questionnaire was used to collect the data. The respondents completed the Almost Perfect Scale-Revised, Dyadic Almost Perfect Scale, Marital Satisfaction Scale, and Attitudes toward Seeking Professional Psychology Help Scale. Confirmatory factor analysis was used to examined the instruments and the results indicated that construct validity were achieved. The latent mean difference in perfectionism and marital satisfaction by counseling help-seeking attitudes were tested using multigroup invariance analysis. The respondents with negative attitudes toward counseling help-seeking (n = 159) reported a higher latent mean in perfectionism but a lower latent mean in marital satisfaction compared to those with positive attitudes toward counseling help-seeking (n = 168). The implications of these findings for counseling services are discussed.

This study aimed to verify the psychometric properties of the Polish version of the Grit-S questionnaire. Grit is understood here as the perseverance and passion for long-term goals, and it encompasses two dimensions: Consistency of Interest and Perseverance of Effort. The sample comprised N = 270 participants aged 18–34 (Mage = 20.79). We performed confirmatory factor analyses to verify the dimensional structure of grit, multi-group confirmatory factor analysis to compare the structure across gender, and correlation analysis to examine external validity (exploring the correlations between grit, procrastination, and well-being). Findings showed satisfactory parameters for Grit-S including: reliability, structural and external validity, and measurement invariance across gender groups. The results support the possibility of using the Grit-S questionnaire in research exploring the predictors of success.
