Tab.2:
Daumenregeln für die Interpretation des RMSEA - Maßes
(Browne&Cudeck 1993)
RMSEA-Maß:
RMSEA 0,05
Beurteilung des Modellfits:
Guter Fit: Modell bestätigt.
0,05 < RMSEA 0,08 Mäßiger Fit: Modell tendenziell bestätigt.
RMSEA > 0,10
Schlechter Fit: Modell widerlegt.
Hayduk (1996) bezieht ausdrücklich Stellung gegen die sich abzeichnende Flut neuer Anpassungmaße:
„Researchers interested in structural equation modeling as a tool, and not as a vocation, are
advised to awoid detailed pursuit of the plethora of new fit indices for the next few years. For
most purposes it is sufficient to report the $ 2 test (and its probability) as long as this is complemented
by a discussion of model parsimony as evidenced in the $ 2 degrees of freedom, a
discussion of the degree of test sensitivity provided by the sample size, a report of the adjusted
goodness of fit index (AGFI) and a discussion of any noticeable patternings in the residuals.
Having fully reported and discussed $ 2 and having mentioned the AGFI index, one should turn
one‘s attention to more detailed indices of particular components of the model fit, or to alternative
models, or to equivalent models, or to considerations of the styles of data that might
substantively distinguish between models, or whatever it is that is of import in the relevant
literature.“ (Ders. 1996, S. 201)
