QUESTIONNAIRE RELIABILITY CHECKING

Questionnaire is a research instrument for gathering information from the respondent through research questions formulated from the objectives of the study.

A questionnaire is not reliable until the internal consistency has been tested by conducting a pilot study of the questionnaire where Cronbach’s Alpha Coefficient Test is implemented.

Cronbach’s Alpha Coefficient Test is a reliability test conducted with SPSS in order to measure the internal consistency.

The following are the ranges of Cronbach’s Alpha Coefficient Test considered as:

Excellent                   0.93-0.94
Strong                         0.91-0.93
Reliable                      0.84-0.90
Robust                        0.81
Fairly High                0.76-0.95
High                           0.73-0.95
Good                          0.71-0.91
Relatively High       0.70-0.77
Slightly Low            0.68
Reasonable             0.67-0.87
Adequate                0.64-0.85
Moderate                0.61-0.65
Satisfactory            0.58-0.97
Acceptable             0.45-0.98
Sufficient               0.45-.096
Not Satisfactory   0.40-0.55
Low                         0.11

But according to Griethuijsen et al (2014), the threshold or cut-off as an acceptable, sufficient or satisfactory level is normally seen as ≥0.70 or >0.70.
