CHAPTER 3 RESEARCH METHODOLOGY

3.5 Examining the Quality of the Instrument

3.5.1 Face validity was conducted using the index of item-objective congruence.

Seeking the index of item-objective congruence by the following experts:

1.Assoc. Prof. Dr. Wichai Kanchanasuwon, Faculty of Management Science, Prince of Songkla University

2.Asst. Prof. Dr. Juthamanee Trakulmuduta, Faculty of Management Science, Prince of Songkla University

3.Dr. Sorawit Isaro, Faculty of Management Science, Prince of Songkla University

The mean of the item-objective congruence from the three experts was 0.83, meaning that the items were strongly congruent. The experts suggested adjusting sentences and words to be more clear for better understanding. The questionnaire was adjusted and pretested to collect the data.

Test of face validity (Tirakanan, 2010) 0.00-0.0.49 mean Improvement is required.

0.50-1.00 mean It is consistent with the criteria and can be used.

3.5.2. Seeking discrimination in the measurement

Discrimination was sought at the experimental stage of the data collection using the questionnaire before the questionnaire was used to collect the real data.

3.5.2.1. Test of the questionnaire

3.5.2.1.1 Twelve questionnaires were sent by post and eight questionnaires were returned. The details of the question items are as follows.

Discrimination was sought to separate the question items responded to by the respondents that work on innovation and the question items responded to by the

respondents that do not work on innovation. Discrimination of the whole questionnaire ranged between 0.54 and 0.83, which is quite high. Therefore, each question item can be used for data analysis.

Criteria for considering discrimination (Ebel, 1991)

-1 means poor discrimination, and improvement is needed.

Below 0.19 means poor discrimination, and improvement is needed.

0.20- 0.29 means fair discrimination, and improvement is probably needed.

0.30-0.39 means that discrimination is moderately good.

0.40 -1.00 means that discrimination is extremely good.

3.5.2.3. Questionnaire reliability analysis

Reliability of the questionnaire was analyzed within two periods: while the questionnaire was tested and while the questionnaire was used in the study. The results of the reliability are shown below.

3.5.2.3.1 Cronbach’s alpha coefficient of the reliability of the questionnaire during the trial was 0.98, considered highly reliable.

3.5.2.3.2Cronbach’s alpha coefficient of the reliability of the questionnaire used in the study was 0.98, considered highly reliable.

3.5.2.3.3 Cronbach’s alpha coefficient of the reliability of each variable to be used in the confirmatory factor analysis had to be 0.70 or greater.

3.5.2.3.4. Test of the relationship among the independent variables (multicollinearity)

The study employed a test to assess

multicollinearity to indicate if there was no correlation between the independent variables to prevent a redundant measurement that would make predicting the coefficient inaccurate. It was found that the VIF did not exceed 10 and tolerance was greater than 0.
