Measuring nursing power within organizations.
OBJECTIVE
To describe the Sieloff-King Assessment of Departmental Power (SKADP) instrument and the psychometric evaluation of both the SKADP and its revision: the Sieloff-King Assessment of Group Power within Organizations (SKAGPO) instrument.


METHODS
A survey of 357 chief nurse executives in the United States to psychometrically evaluate the SKAGPO.


METHODS
Psychometric evaluation of the SKAGPO included: (a) internal consistency reliability using Cronbach's alpha coefficient, split-half with the equal-length Spearman Brown Correction Formula, and item analysis; (b) concurrent criterion-related validity; and (c) factor analysis.


RESULTS
Cronbach's alpha coefficient for the SKAGPO was .92. Subscales' alphas ranged from .63 to .88. Item-total correlations ranged from .24 to .68, with an average item-total correlation of .48 (n = 334). Concurrent criterion-related validity was supported.


CONCLUSIONS
The SKAGPO and the related subscales showed initial reliability and validity.
