Development of Psychiatric Nursing Care Traits Questionnaire Based on the Interpersonal Circumplex Model

-Consideration of Reliability and Validity-

Abstract

The purpose of this study was to clarify the mathematical/statistical structure of psychiatric nursing traits. For this purpose, we developed questionnaire on the psychiatric nursing care traits, namely the Interpersonal Circumplex for Psychiatric Care (IPC-PC), which adopted the Interpersonal Circumplex (IPC) model. On the basis of IPC’s previous research, 66 items questionnaire were developed to measure the characteristics of psychiatric nursing, and 205 psychiatric nurses were investigated. We performed the principal component analysis and confirmative factor analysis. A total of 32 items were selected, and the following eight factors were extracted: controlling, selfish, refusing, self-negating, dependent, accepting, confident, and self-affirming. Reliability, validity, and annular structure (two-dimensional axial structure, correct order, and equidistance) of IPC-PC were confirmed by the same statistical method used in the previous research. The eight factors of IPC-PC used in our study had a concept similar to that of the previous study; however, we put more emphasis on the nursing care behaviors, particularly the aspects of psychiatric nursing management and care precision.
