Adaptation of the Gerontological Nursing Competence (GeroNursingCom) instrument to Turkish: Validity and reliability...

The aim of this study was to conduct a Turkish validity and reliability study of the Gerontological Nursing Competence Scale and to adapt the scale to Turkish culture.

As the number of older people increses, gerontological nursing requires specialized expertise in older people care. High-quality basic education and further education guarantee good competence in gerontological care.

A methodological study of instrument translation and validation.

The study was methodological and the sample consisted of 530 university students who agreed to participate in the study. Data were collected by online interview method using the Introductory Information Form and Gerontological Nursing Competence Scale (GeroNursingCom). Before starting the study, permission was obtained from the ethics committee, the relevant institution, the scale owner and the students. Language equivalence and content validity of the scale were ensured and Confirmatory Factor Analysis Models (CFA) was conducted. Cronbach Alpha and item-total correlation analysis were used for the reliability of the scale.

The scale was compatible in terms of linguistic fidelity Content Validity Index (CVI) (Language)=0.97 and content fidelity CVI (Content)=0.96. The CFA results showed that the χ2/sd value was 1.861 and since this value was less than three, it can be stated that the model provided an excellent fit to the data. Comparative Fit Index (CFI) and Non-normalized Fit Index (NNFI) values were determined as 0.99 and 0.99 respectively and these values being above 0.90 indicate that the model provides an excellent fit to the data. Square Root of Standardized Errors (SRMR) index was 0.045 and Root Mean Square Error of Approximation (RMSEA) index was 0.040 and these values were less than 0.080, indicating that the model provided an excellent fit to the data. The Cronbach's alpha reliability coefficient of 0.97 was found to be highly reliable and the Cronbach's alpha reliability coefficients calculated for the sub-dimensions ranged between 0.77 and 0.91.

It was determined that the gerontological nursing competence scale is valid and reliable for nursing students and can be used in both student and working nurses living in Turkey.
