CHAPTER 4 RESEARCH ANALYSIS AND RESULTS

4.3 RELIABILITY AND VALIDITY ANALYSES

4.3.1 RELIABILITY TEST

In this section, the reliability of research constructs was also tested. Reliability refers to the consistency of a measure, whereas internal consistency is that the individual items of a scale should be measuring the same construct and be highly interrelated. The most commonly ways of testing internal consistency are computing Cronbach’s alpha and item-to-total correlation. When the item-to-total correlation is above 0.4 and the reliability coefficient alpha value is above 0.7, the items demonstrate high internal consistency and hence reliability of each dimension (Nunnally and Bernstein, 1994). This study adopted the total sample (n=3132) to test if the measure scales are reliable.

Table 4.7 shows the internal consistency for all research constructs. All items within a factor or a construct have a high coefficient of item-to-total correlation

(0.421 – 0.873), and this suggests a high degree of internal consistency for each dimension. Furthermore, the Cronbach’s alpha value of each construct is high (0.787 – 0.926), which confirms the consistency of the measurement variables.
