Narrowing a topic requires you to be more specific about your research interest and can help you to develop a thesis.
Before you look for articles, you should determine what your topic is and identify keywords and phrases.
State your topic as a question: How does parenting style affect adolescent development of independence?
Parenting Style: Democratic parenting, permissive parenting or authoritarian parenting
Adolescent Development: Physical development, cognitive development, or social/emotional development
Independence: Autonomy, self-sufficiency, competence
Once you have identified keywords and phrases and synonyms, you are ready to formulate searches.
For example, for the topic "How does parenting style affect adolescent development of independence?" you might search for:
"parenting style" AND "Adolescent development" AND independence
If you don't find anything with that search, then you may want to think of adding some synonyms to your search:
"authoritarian parent*" AND "social development" AND (autonomy OR competence)
