Reliability and validity of the Turkish version of the Barriers to Nurses' Use of Physical Assessment scale

Abstract

Aim: This study aimed to translate the Barriers to Nurses' Use of Physical Assessment Scale into Turkish and assess the new version's validity and reliability.

Methods: This was a methodological study to verify the linguistic equivalence of the scale through the translation/back-translation method. Twelve experts in health assessment confirmed the scale's content validity. Along with the Barriers to Nurses' Use of Physical Assessment Scale, an information form, including socio-demographic features, was distributed to 380 nurses, who consented to participate in the research. Data were collected between July 2017 and April 2018. Internal consistency, factor analysis and test-retest reliability were used to determine consistency over time and intraclass correlations.

Results: The content validity index of the scale (0.963) was calculated following confirmation of its language equivalence. With the confirmatory factor analysis, it was determined that the fit index values were at an acceptable level and the model was suitable. The factor analysis clustered factors in seven domains. The overall internal consistency coefficient was 0.822. All subscales and the overall scale showed high intraclass correlations.

Conclusion: The Turkish version of the Barriers to Nurses' Use of Physical Assessment Scale is a valid and reliable instrument.
