ABSTRACT
Background:
Self-efficacy expresses the individual’s belief in their ability to take up and continue actions in order to achieve a particular result and cope with various life events. For people with multiple sclerosis (MS), self-efficacy is an im-portant resource because it affects how they adapt to the disease, and influences their motivation, health-related behavior and physical activity. It also has a great impact on their quality of life. Because of the lack of tools for meas-uring self-efficacy in Polish patients with multiple sclerosis, the goal of the current study was to develop a Polish language version of the Liverpool Self-efficacy Scale (LSES) and assess its validity and reliability.
Participants and procedure:
A total of 175 people diagnosed with MS took part in the study. A Polish version of the LSES, the Sense of Coherence Questionnaire (SOC-29), the Resiliency Assessment Scale (SPP-25), the Health-Related Hardiness Scale (HRHS), the Acceptance of Illness Scale (AIS) and the Multiple Sclerosis Impact Scale were applied.
Results:
Confirmatory factor analysis, reliability analysis using α and ω coefficients, and two measures of validity (content and criterion validity) were used in order to validate psychometric properties of the Polish version of the LSES. Our analyses confirmed a good fit of the one-factor and two-factor models.
Conclusions:
The results indicate that the Polish version of the LSES is a useful and valuable tool for assessing levels of self-efficacy in Polish patients with multiple sclerosis. The scale can be used for both clinical and research purposes.
