Background
The aim of this study was to examine the psychometric properties of the Polish version of the Short Hopeless-ness Scale in an undergraduate student sample. The scale was originally developed as a brief measure of hopelessness for large scale epidemiological surveys and is based on two commonly used measures of hope-lessness.

Participants and procedure
A total of 4098 students from different Polish universities took part in the study. Confirmatory factor analysis (CFA) was used to test the model fit. Pearson correlation coefficients were used to investigate the relationship between hopelessness scale and criterion variables.

Results
Due to the lack of fit of the initial congeneric, unidimensional model, the lowest loading item was removed, and a tau-equivalent model with three items was tested. The tau-equivalent model showed a good fit to the data. The scale had adequate reliability. Hopelessness was positively related to anxiety, depression, and stress and negatively related to the quality of life, health, and self-esteem.

Conclusions
The study provides evidence of good psychometric properties in terms of factorial structure, reliability and crite-rion validity of the shortened 3-item Polish version of a hopelessness scale. Future studies should investigate its predictive value, especially in terms of suicidal ideation and behaviour, as well as other health outcomes.

Shopping Addiction Is Driven by Personal Focus Rather than Social Focus Values but to the Exclusion of Achievement and Self-Direction

Streszczenie: The aim of the study was to investigate the relationship between shopping addiction and a comprehensive model of motivational principles conceptualized within the Schwartz’s values theory. On the basis of previous research on the associations of shopping addiction with personality and particular values, it was hypothesized that shopping addiction would be positively related to all personal focus values that refer to self-enhancement and openness to change, and negatively related to social focus values that emphasize conservation and self-transcendence. The Bergen Shopping Addiction Scale, a tool based on common addiction components, and the Short Schwartz Values Survey were administered to 1156 undergraduate students. The results mostly supported the hypotheses; however, contrary to what was expected, shopping addiction had negative associations with achievement and self-direction. These results suggest that while compulsive buyers are strongly motivated to pursue prestige and pleasurable, hedonistic life, they diminish the importance of productivity or creativity that would allow achieving their goals. To some extent, shopping addiction could be understood as a striving for the ideal lifestyle with minimum effort by those who struggle with maintaining positive and healthy social relations. The findings contribute to the understanding of individual differences related to the development and persistence of shopping addiction.

Streszczenie: Short scales are becoming increasingly popular in social and behavioral sciences. Often times they are convenient, valid and reliable which makes them particularly useful in certain contexts, such as large scale surveys. The aim of the study was to investigatie measurement invariance of the Polish version of the Mini-IPIP Shortened Measures of the Big-Five Domains (the Mini-IPIP) between a student sample (927 persons) and an employee sample (723 persons). The instrument consists of 20 items, four for each subscale and has a 5-point Likert-type response format ranging from 1 (Strongly disagree) to 5 (Strongly agree). Data were gathered between 2013 and 2017 as a part of subsequent research projects. The results showed that the scale has satisfactory model fit in both samples and indicated strong measurement invariance between the groups of students and employees. The data supports the validity of the Polish version of the Mini-IPIP.

Single-item self-report measure of learning engagment: What does it measures?

Streszczenie: This article presents the results of a research examining the validity of single-item, selfreported measure of students’ subjective learning engagement. The study took place in April 2019 on a sample of 148 female second year early education students from the University of Gdańsk. Indicators of different aspects of learning engagement were used as predictors of the answer to the question: “How engaged in learning are you?” with a 9-point Likert type response format ranging from 1 – Very weakly to 9 – Very strongly. The regression model including several independent indicators of engagement explained 52% of the variance of the single-item measure. The gathered data support validity of the single-item measure of learning engagement. The results are congruent with previous research on validity and reliability of the scale.

Streszczenie: Adverse health-related consequences of perfectionistic over-involvement in work are well-documented among professional musicians.The aim of this study was to investigate a recently developed concept of “study addiction” among students of music academies. Study addiction has been defined within the framework of theory and research on work addiction as a potential behavioral addiction.
