Development and psychometric testing of the preceptors' orientation competence instrument (POCI).

To develop and psychometrically test a Preceptors' Orientation Competence Instrument measuring orientation competence of nurses working as new employee preceptors. Competence of nurse preceptor is essential for a successful preceptorship and thus nursing staff´s commitment to the organization. Instrument development according to the COSMIN guidelines. Four phases were implemented: 1) establishment of the theoretical framework, modification of the validated Mentor Competence Instrument and generation of new items; 2) content validity testing; 3) structural validity testing; and 4) internal consistency testing. Content validity was evaluated by 14 experts using content validity index methods. Structural validity was evaluated using exploratory factor analysis with a convenience sample of 844 Finnish nurses. Internal consistency was evaluated by measuring Cronbach's alpha. The content validity index of subdimensions of the instrument ranged from 0.80 to 0.94 for relevance and 0.80–0.94 for clarity. Exploratory factor analysis resulted in a seven-factor model with 53 items (61.62% of total variance): preceptor characteristics, goal-oriented orientation, guidance in reflective discussion, knowledge of work unit orientation practices, creation of a supportive learning atmosphere, preceptor motivation and giving of developmental feedback. Cronbach's alpha values varied from 0.79 to 0.93. Preceptors' Orientation Competence Instrument demonstrated adequate psychometric properties based on content and construct validity as well as internal consistency. Therefore, it is useful for self-evaluation of orientation competence of nurses working as new employee preceptors. [ABSTRACT FROM AUTHOR]
