I conducted both direct and indirect measures. It seems like there is positive correlation for all items in the direct measure (attitude/subjective norm([SN]/perceived control[PC]) in relation to intention (with Cronbach > 0.7).
But when I compared the indirect parameters to intention, there seems to be no correlation whatsoever. The surprising thing is that there is a good correlation between attitude/PC/SN in both direct and indirect measures.
Any suggestions?
Could you please specify what you mean by direct and indirect measures?
It is impossible to answer your question without detailed information about your measures and analyses. I suggest you consult the TPB website:

Dear Prof Ajzen,
It is great to hear your feedback. I am working on an analysis of sickness certification behaviour amongst physicians. I wanted to analyze their intention of providing sickness certification to patients at primary care clinics.
I followed each step in designing the questionnaire. After pilot testing the initial draft, I came up with 2 questionnaires, one to assess direct measures and another to assess indirect measures. I also made it point to reassess the temporal stability of the indirect measures by testing the second questionnaire after 2 weeks.
Finally when I did the analysis, I managed to get two different outcomes from both direct and indirect measures (scale reliability and temporal stability was good for both direct and indirect measures after omitting some items in the scale). For the direct measure, intention was only strongly correlated to the attitude of the physicians towards patients. However in the indirect measure, intention was only strongly correlated to subjective norm composite score (but very weak correlation though).
I was thinking of two possibilities 1) Only the attitude of the physician had some effect on their intention to provide sickness certification to patients 2) My questionnaire is flawed despite my extensive attempt to perform the pilot draft at the very beginning.
I will look into the website and see what I have missed. It would be great (and if it is of not much trouble) if you would like to have a look at my measures and analyses. I could send it to you. Thanks so very much.

Dr. Azjen:
Greetings!
I am familiar with some aspects of your theoretical perspectives, on TPB. The first time I read given theory, it allowed me to see, why true health behaviors are not easily formed. Would TPB be applicable to explaining, the behavior of criminal psychopaths?
