The options are missing in this question; here is the complete question:
A researcher who starts with an interest in delinquency and then identifies the traits associated with that category of behavior is taking a ________ approach.
A. Typological
B. Single-trait
C. Many-trait
D. Essential-trait
The answer to this question is Many-trait
Explanations:
Social or behavioral phenomena such as addiction, depression, aggression, or delinquency can be studied through traits, which are characteristics that influence the behavior and thoughts of individuals. Moreover, different approaches can be used for this purpose. In the case of the many-trait approach, this studies the phenomenon by identifying many traits associated with it, which helps researchers to know the traits that contribute to the specific behavior.
This is the approach used by the researcher to study delinquency because he focuses on identifying multiple traits directly related to the phenomenon. Moreover, in other methods such as the single-trait or the essential-trait, only one or a few traits are used.
