Respected academicians,
I will try to articulate my confusion as best as I can.
1) In my current study which investigates consumers' acceptance of a mobile payment system, I am using (and extending) TAM.
2) Many studies which use TAM with its constructs e.g. perceived usefulness and perceived ease of use, have actual or existing users as their sample population.
3) If I were to investigate non-users (because adoption is yet to be widespread), would this model still hold? I mean, how can a non-user answer questions related to "perceived ease of use" when he/she has never experienced/used the technology before?
Although arguably this is merely perception...
4) When I refer to studies which use TAM and have non technology users as their sample population, they often include an explanatory video to demonstrate the use of the technology before having their respondents to answer the questionnaire. So is this the same measure that I should take?
I am at the stage of having my questionnaire reviewed by experts for content validation and I end up with this question marks following several discussions.
Can someone advise me accordingly?
Your question is valid. But why do not you use UTAUT instead of TAM. I know in both cases non-technology users will have issues while filling questionnaires but do not you reckon this is your research which you want to do. If they will not respond, I mean if they will give their response near to neutral state, ultimately no one had tried to guided them in developing their beliefs regarding ease of use, usefulness, performance expectancy, effort expectancy etc. But if you want to measure their intentions, then before collection of data, explain them via giving a brief description of the technology features or by showing video is a good idea.
Dear Adil Bilal ,
Thank you for your clarification. Much appreciated.
