The development and validation of Discipline-oriented Measurement Model for Matthayomsuksa 3 Using Affinity Diagram techniques and multitrait - multimethod analysis.

Abstract

The objectives of the research were to development and checking of validity
of the model of factors influencing discipline of Matthayomsuksa 3 using affinity diagram
techniques, and validate the convergent validity and discriminant validity by multitrait -
multimethod analysis ( 4 traits 2 method ). The sample were 580 students under the
Primary Education Service Area Office of Kalasin , obtained using the multi-stage random
sampling technique. Two instruments used in the study were : Scale 1 was a measure of
discipline-oriented situations test with discriminating powers (t-test ) ranging 3.024 - 9.798
and a reliability of 0.904 ; Scale 2 was a measure of discipline rating scale test with
discriminating powers (rxy) ranging 0.259 - 0.908 and a reliability of 0.946. Data analysis based
on descriptive statistic, the Index of consistency, the Pearson’s Product moment correlation,
the Cronbach’s alpha coefficients . Confirmatory factor analysis and multitrait -multimethod
analysis was carried out using Mplus version 6.11.
The results of research showed that: 1) The model of discipline of Matthayomsuksa 3
students were in harmonious congruence with the empirical data using statistics to measure
levels of harmony with  2 =120.707 , df = 19 , p = 0.000 ,  2/df = 6.353 , CFI = 0.961 , TLI
=0.942 , RMSEA = 0.096 , SRMR = 0.036. 2) The multitrait -multimethod analysis of model fit
with empirical too  2= 2.092 , df = 5, p =0.8362 ,CFI =1.000 ,TLI= 1.006 , RMSEA =0.000,
SRMR = 0.010 and  2/df = 0.4184. The statistical analysis indicated that, a measure of
discipline-oriented situations test were the Reliability, the discriminant validity and
convergent validity.
