Description: The purpose of this research was to assess the reliability and validity of a patient classification instrument for psychiatric patients (NPH-PCI) based on the Johnson Model for Nursing. Equivalence reliability and criterion-related validity were the two specific psychometric properties investigated.

Data were collected by direct observation of patient behaviors at the UCLA Neuropsychiatric Hospital from August, 1982, through November, 1984. A purposive sample was selected from four child inpatient units for four-hour observations by three independent raters (staff, shift coordinator and observer). At the completion of each observational period, the Behavior Criteria Checklist--comprised of a patient behavior checklist, subsystem category rating scale and system category rating scale--was completed.

Mean inter-rater agreements, computed on 451 patient observations with respect to patient behaviors for three comparison paired groups (staff, shift coordinator and observer) exceeded the 60% criterion for inter-rater reliability. Mean inter-rater agreements ranged from 67% to 84%. Mean inter-rater agreements of staff and shift coordinator pairs were above the 60% criterion for the system category ratings (67%) and most subsystems' category ratings (60% for dependency to 68% for eliminative), with the exception of sexual (57%) and aggressive-protective (57%) subsystems.

Findings showed that all R('2) values for subsystems categories (ranging from .08 for sexual to .36 for achievement) had low to moderate explanatory power; but that the R('2) value for the system category (.52%) had good explanatory power. The moderate R('2) values for the subsystem categories suggest that further work is needed to identify additional relevant patient behaviors for inclusion within each subsystem.

Findings also indicated that the system category was generalizable across inpatient units, age and sex groups. Affiliative and dependency subsystems categories were also generalizable across these same groups and units.

In conclusion, the NPH-PCI appears promising for further development. It is anticipated that additional studies will provide further support for the reliability and validity of the NPH-PCI.
