Some of the threats noted were sampling and recruitment. Sampling technique may have a problem in randomised control trials when the potential participants are not prepared to opt for treatment in randomised basis. Similarly, recruiting subjects to participate in clinical trials may be difficult. On the other hand, qualitative research has been noted to be time consuming and important issues may be overlooked during the study. in essence both methods are appropriate to conduct a research, and can contribute greatly to the scientific body of knowledge (Carr,
