In your initial study, you noticed that your participants tended to say they strongly agreed with all of the items on your questionnaire when doing a follow up study, how would yout ell that your original participants suffered from acquiescence bias

I could tell that your original participants suffered from acquiescence bias due to the respondents answering strongly agree. The questionnaire may be a bit vague or the respondents had a different understanding on it and in return answered without really thinking. An acquiescence bias is the tendency of the respondents to affirm to the type of question it asks without confirming the details.
