Do you mean validity in instrument/questionnaire design or qualitative validity? I'm doing quantitative research developing an instrument. im a little worried that you are unsure of measuring validity at this stage of your research. Qualitative/quantitiative validity is very different and greatly depends on what you are doing. I'm developing an instrument and looking at construct validity using confirmatory and exploratory factor analysis (also a stage before this developing items to satisfy content validity) and criterion validity at the very least where you validate your instrument with a valid and reliable measure. Reliability is also important with questionnaire design so looking at internal consistency (cronbach's alpha). Otherwise you would be analysing responses of the questionnaire means, standard deviations etc. Who is providing guidance for you? I need more information to help you
