A pilot study (N= 20 respondents) was then conducted and respondents
were asked to complete the questionnaire twice, within a 2-week interval
between the first and second time. Consistency of response was noted
and no problems or misunderstandings arose. Test-retest reliability
was high (r= 92%). After all 325 questionnaires had been collected,
Cronbach's reliability alpha was assessed to test internal consistency of
the questionnaire contents and found to be high (α= .86; 13 questions).
