Background: Well developed and validated lifestyle cardiovascular disease (CVD) risk factors questionnaires is the key to
obtaining accurate information to enable planning of CVD prevention program which is a necessity in developing countries.
We conducted this review to assess methods and processes used for development and content validation of lifestyle CVD
risk factors questionnaires and possibly develop an evidence based guideline for development and content validation of
lifestyle CVD risk factors questionnaires.
Materials/Methods: Relevant databases at the Stellenbosch University library were searched for studies conducted between
2008 and 2012, in English language and among humans. Using the following databases; pubmed, cinahl, psyc info and proquest.
Search terms used were CVD risk factors, questionnaires, smoking, alcohol, physical activity and diet.
Results: Methods identified for development of lifestyle CVD risk factors were; review of literature either systematic or
traditional, involvement of expert and /or target population using focus group discussion/interview, clinical experience of
authors and deductive reasoning of authors. For validation, methods used were; the involvement of expert panel, the use
of target population and factor analysis.
Conclusion: Combination of methods produces questionnaires with good content validity and other psychometric properties
which we consider good.
