Sociodemographic and work-related variables affecting achievement motivation assessed with the LMI among professionally active nurses under study.

Achievement motivation is a particular category of an employee's motives towards professional development, associated with positive emotions in challenging task-oriented situations. Our objective was to determine the effect of selected sociodemographic and work-related variables on achievement motivation according to the Achievement Motivation Inventory (LMI) for professionally active nurses. The study included 830 Polish nurses. We have applied the diagnostic survey method, the questionnaire technique, using the LMI and the authors' survey questionnaire. A statistically significant (p < 0.05) positive correlation was demonstrated between the respondents' age and the LMI scales: Independence (r = 0.15), Confidence in success (r = 0.11), Dominance (r = 0.10), Eagerness to learn (r = 0.12), Compensatory effort (r = 0.08), Flow (r = 0.10), Self-control (r = 0.14). With respect to the effect to educational background on achievement motivation according to the LMI, it was concluded that for all statistically significant relationships, a higher mean level of the characteristic under study was noted in the group of respondents with higher education compared to the individuals with secondary education (p < 0.05). Data analysis showed statistically significant differences (p < 0.05) in the achievement motivation according to the LMI of the nurses under study, depending on the completion of the nursing specialisation programme. For all statistically significant differences, a higher mean level of the characteristic under study was noted in the group of nurses who use EBNP at work compared to those who do not use EBNP. The strongest effect of the impact of this variable on the characteristics under study was noted for the variables Eagerness to learn (d = 0.41; 95% CI [0.27; 0.55]), Preference for difficult tasks (d = 0.39; 95% CI [0.25; 0.54]), Self-confidence (d = 0.39; 95% Cl [0.24; 0.53]), and Flexibility (d = 0.34; 95% Cl [0.19; 0.48]).
