Research by de Visser and colleagues (2015) on reducing alcohol consumption demonstrated that when it comes to intervention and evaluation,qualitative research methods

A) are of no value
B) must be mixed with quantitative research methods to be useful
C) can provide insights not available through quantitative methods
D) are inappropriate because they have nothing to do with the applied goals of intervention or evaluation

The research by de Visser and colleagues (2015) demonstrated that qualitative research methods can provide insights not available through quantitative methods, particularly when it comes to understanding the attitudes, beliefs, and behaviors of individuals regarding alcohol consumption. Qualitative research can be particularly useful for developing interventions and evaluating their effectiveness, as it can provide a more nuanced understanding of why individuals engage in certain behaviors and what contextual factors may influence their decisions. While qualitative research may need to be complemented by quantitative methods in some cases, it is not true that it has no value, nor is it inappropriate for applied goals of intervention or evaluation.
