Development and reliability and validity of a scale measuring the coping resources for nursing interruptions
Objective To develop and test the reliability and validity of a scale measuring the coping resources for nursing interrup-tions.Methods Guided by six types of resources of the Conservation of Resources theory,a draft scale was developed through litera-ture review,semi-structured interviews,Delphi consultation,and a pilot survey.Then a convenience sample of 547 nurses were se-lected from a tertiary hospital in Hubei Province and a tertiary hospital in Xizang Autonomous Region to test the reliability and validity of the scale.Results Five factors were identified through exploratory factor analysis,accounting for 88.211％of the total variance,and confirmatory factor analysis indicated a well-fitting model(x2/df=2.776,RMSEA=0.058,CFI=0.961,NFI=0.940,and TLI=0.955).The formal scale included 26 items contributing to 5 dimensions:key resources,constructive resources,energies resources,macro resources,and social support.The scale-level content validity index(CVI)was 0.980 and the item-level CVI ranged from 0.923 to 1.000.The overall Cronbach's α coefficient was 0.985 and the test-retest reliability was 0.932.Conclu-sion This scale is valid and reliable for measuring nurses'coping resources in the process of nursing interruptions.
