Development and validation of a hybrid measure of organisational communication satisfactionAmanuel Gebru Woldearegay, Woldearegay, Amanuel Gebru 18 October 2013 (has links)
The purpose of the study was to identify and transform, as necessary, constructs
of communication satisfaction and to develop a hybrid quantitative audit of
organisational communication satisfaction for collectivist contexts that is both
reliable and valid, using Amos Graphics for structural equation modelling. The
objective was also to develop a full latent variable model and to test its fitness to
the data collected from a random sample of civil servants across Addis Ababa’s
civil service bureaus.
The study comprised three sequential parts, namely pilot, exploratory factor
analysis (EFA) (Main Study One) and confirmatory factor analysis (CFA) (Main
Study Two). These were used as per the existing framework in instrument
development and validation. The pilot study indicated the need for more robust
data. After a series of tests, principal factor axis factoring with oblique rotation
was used as the most appropriate for perceptual data, out of several options on
the EFA menu. The initially hypothesised six-factor solution with the dimensions
of horizontal communication, personal feedback, supervisory communication,
communication climate, relational trust and job satisfaction was found to be unfit
for the data on conceptual and statistical grounds and psychometric analyses
which involved the use of eigenvalues and the scree plot.
A more appropriate two-factor solution based on the more precise parallel
analysis strategy was consistent with current research that communication
satisfaction is best conceptualised in terms of informational and relational
domains as operationalised using the EFA procedure. The two-factor solution led
to the formation of a 17-item scale out of the original 30-item measure, with two
latent dimensions namely relational satisfaction and informational satisfaction.
The items of the new EFA-generated organisational communication satisfaction
scale were renumbered consecutively and the scale was cross-validated on a
xiv
new sample of 288 civil servants from the Addis Ababa City Administration. The
cross-validation necessitated model respecification and re-estimation.
The respecified model underwent validation at different levels. All seven aspects
of validity, namely content validity, construct validity, factorial validity, reliability,
convergent validity, discriminant validity and nomological validity, were
addressed and found to be adequate. However limitations are also indicated as
avenues for further enquiry. / Communication Science / D. Litt. et Phil. (Communication)
