Nurses' spiritual attitudes and involvement-Validation of the Polish version of the Spiritual Attitude and Involvement List.

The Polish version of SAIL shows acceptable psychometric properties and construct validity. With the validation of SAIL, future studies can be undertaken with the aim of measuring the personal spirituality of nurses in various settings (hospital vs. community), cultures, and countries, thus increasing the opportunity to compare findings. Moreover, more studies should be performed in order to assess whether there is any connection between personal spirituality and the spiritual nursing care provided to patients.
