Summary
This study validated the Sieloff-King Assessment of Group Power Within Organizations (SKAGPO) using confirmatory factor analysis. The SKAGPO demonstrates acceptable psychometric properties for measuring nursing group power.
Area of Science:
- Nursing
- Organizational Behavior
- Psychometrics
Background:
- Limited empirical research exists on measuring nursing group power.
- Instrument development and middle-range theory building are crucial in nursing research.
Purpose of the Study:
- To report confirmatory factor analyses of the Sieloff-King Assessment of Group Power Within Organizations (SKAGPO).
- To evaluate the psychometric properties of the SKAGPO for measuring nursing group power.
Main Methods:
- Secondary analysis of cross-sectional data from 1999.
- Target population: Chief Nurse Executives (CNEs) of US hospitals.
- Sample: 350 CNEs from 600 selected hospitals.
- Second-order confirmatory 8-factor analysis.
Main Results:
- Factor loadings ranged from .43 to .89.
- The proposed model showed an acceptable fit (GFI=.82, CFI=.86, RMSEA=.06).
- Statistical support was found for the proposed model, leading to an alternate, better-fitting model.
Conclusions:
- The Sieloff-King Assessment of Group Power Within Organizations (SKAGPO) possesses acceptable psychometric properties.
- The study provides empirical support for the SKAGPO's utility in measuring nursing group power.

01:21Voltammetry: Factors Affecting Measurements
A current produced due to the redox reactions of the analyte at the working and auxiliary electrodes is called a faradaic current. The reaction can be divided into two types. The current generated due to the reduction of the analyte is called cathodic current, and it carries a positive charge. In contrast, the current produced by analyte oxidation is known as an anodic current, and it has a negative charge. The applied potential at the working electrode determines the faradaic current flow, and...
01:15Data Validation
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

02:46Uncertainty in Measurement: Reading Instruments
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...
01:19Fineness Modulus
The fineness modulus (FM) of aggregate is a numerical index that measures the coarseness or fineness of the particles. It is calculated by adding the cumulative percentages of aggregate retained on each of a specified series of sieves and dividing the sum by 100.
Consider performing sieve analysis on sand through a set of ASTM sieves. The weight of aggregate retained in each sieve and pan placed at the bottom is recorded, as given in Column B of Table 1.

01:22Atomic Absorption Spectroscopy: Instrumentation
An atomic absorption spectrophotometer (AAS) comprises several components: a radiation source, an atomizer, a monochromator, and a detector. The radiation source can be a hollow-cathode lamp (HCL) or an electrodeless-discharge lamp (EDL), both of which provide a narrow emission line of the required wavelength. However, some instruments use continuum sources and high-resolution monochromators to achieve a narrow range of radiation.
The atomizer used in AAS can be either a flame atomizer or an...

01:22Compacting Factor test
The compacting factor test is a method used to assess the workability of concrete. It is especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...
