Sometimes you don't know enough about your topic yet to refine it, and a little background reading can help.
These are some good online reference sources available through the BCIT Library:
Too broad | Depression |
Too narrow | Cognitive stimulation therapy as a treatment of depression in the elderly with dementia |
Good | Forms of therapy in the treatment of elders with depression |
If your topic is too broad, you might try asking some of these questions to help refine it:
Who might this apply to? Is there a particular population or demographic group you could focus on?
What? Is there a specific aspect of this topic that is most interesting to you?
When? Does it make sense to limit your topic to a particular time period?
Where? Could you consider your topic within the context of a particular place or geographic region?
