The critical appraisal of the research question used in a study is vital to the application of the findings to clinical practice.
Without devoting appropriate resources to developing the research question, the quality of the study and subsequent results may be compromised. In addition, a hypothesis typically takes the form of an if-then statement so you can test it with your research. During the initial stages of any research study, it is therefore imperative to formulate a research question that is both clinically relevant and ch hypothesisthe primary research question should be driven by the hypothesis rather than the data.
Also, simply saying 'light' is too vague to be useful or researched, so it was turned into 'amount of light. Note that the study objective is an active statement about how the study is going to answer the specific research question. You believe (based on theory and the previous research) that the have an effect, but you are not confident enough to hypothesize a direction and drug will reduce depression (after all, you've seen more than enough promising ents come along that eventually were shown to have severe side effects that ed symptoms).
