To find the evidence you need, it is key to make a research question searchable. Let's explore how to do this using this research question:
How effective are mobile phone interventions in smoking cessation?
With this research question in mind, here is how it can be made 'searchable' in a database:
Step 1: Isolate the main concepts of your research question
mobile phone interventions; smoking cessation
Step 2: Create a list of search terms for each concept
mobile phone = smartphone, smart phone, cell phone, cellular phone, text, short messaging service, SMS
smoking cessation = quitting smoking, stopping smoking, smoking prevention
We will not include the word 'intervention' as literature discussing mobile phones and smoking cessation would likely already be in the context of mobile phones as an intervention.
Step 3: Use your search terms to create a single search statement
(smartphone OR smart phone OR mobile phone OR cell phone OR cellular phone OR text OR short messaging service OR SMS) AND (smoking cessation OR quitting smoking OR stopping smoking OR smoking prevention)
Tips: As each database is unique, it is important to consider if you need to tweak your search strategy for each database you search. Also, it is useful to consider using a combination of keywords (words appearing in the title and abstract of an article) and database subject headings (controlled vocabulary of the databases, such as MeSH, Emtree).
