[Abilitest battery - psychometric properties: a preliminary study]. / Bateria testów abilitest ­ wlasnosci psychometryczne narzedzi: badania wstepne.

BACKGROUND: Cognitive efficiency is crucial for many areas of human activity. It affects the employees' efficiency and safety at the workplace. An important element of the prevention of accidents at work is the appropriate professional selection, which consists in checking the characteristics of candidates needed for a given position, and for this purpose, a psychological diagnosis is carried out. The aim of the study was to develop tools for cognitive diagnosis that are characterized by good psychometric properties. MATERIAL AND METHODS: Tools for the diagnosis of simple reaction time (Abili-time), choice reaction time (Abili-select), prolonged attention (Abili-space, Abili-digit), and working memory (Abili-langmem, Abili-mathmem) were developed. Validation studies were conducted with 221 individuals aged 20-60 to assess relevance and reliability (internal consistency and temporal stability), and with the participation of 61 in a retest 3 months after the first measurement. Paper tests (CTT, TUS, Digit Span from WAIS-R(PL)) and tests from the Vienna test system (RT, SIGNAL, CORSI, ALS) were used to assess validity. RESULTS: The analysis showed that the Abili-time and Abili-select tests have satisfactory internal consistency. Analysis of temporal stability showed significant test-retest correlations for Abili-select, Abili-space, Abili-digit and Abili-langmem. Abili-time had slightly lower temporal stability. The temporal stability of Abili-mathmem was not confirmed. Significant correlations were obtained between the results of the developed tools with measures measuring similar constructs. CONCLUSIONS: The conducted research confirms the validity and reliability of Abili-time, Abili-select and Abili-space. Further work is needed on working memory tests, which are noteworthy due to the lack of other tools available on the market to test these functions. Further research should involve more people as well as carrying out standardization work. Med Pr. 2023;74(2):103-18.

[Job resources and work engagement: the mediating role of basic need satisfaction]. / Zasoby a zaangazowanie w prace: mediacyjna rola satysfakcji potrzeb podstawowych.

BACKGROUND: Contemporary work psychology indicates that improving the functioning of employees and organizations takes place not only through the prevention of harmful factors but also through the development of positive attitudes towards work. According to the job demands-resources model, it can be assumed that resources are an important factor leading to work engagement. However, the authors of this concept also suggest that the role of resources is also to meet needs. In turn, according to the self-determination theory, the key to the development of intrinsic motivation and thus also work engagement is the satisfaction of basic needs. Therefore, hypotheses argue that resources in the form of the influence at work, possibilities for development, and social community at work are positively related to work engagement. And also that the satisfaction of basic needs, respectively autonomy, competence, and relatedness, are the mediators of these relationships. MATERIAL AND METHODS: Data were collected among 200 workers aged 18-35, employed to work in direct contact with customers. Job resources were measured with the Copenhagen Psychosocial Questionnaire (COPSOQ II) subscales. Basic psychological need satisfaction was measured with the Basic Psychological Needs Satisfaction and Frustration Scale at Work. Work Engagement was measured with the Utrecht Work Engagement Scale. RESULTS: Regression analyses with mediation effects were performed for 3 models. It has been shown that Influence at work is a predictor of Work engagement and this relationship is mediated by Autonomy satisfaction. Possibilities for development are positively related to Work engagement, in this relationship, the mediator is Competence satisfaction. In the relationship between the Social community at work and Work engagement, the mediator is the relatedness satisfaction. CONCLUSIONS: The results have confirmed hypotheses regarding the mediating role of need satisfaction in the relationship between job resources and work engagement. Despite the limitations of the study, the results obtained confirm and develop the job demands-resources and self-determination theories. Med Pr. 2022;73(5):407-16.
