Which theory suggests that certain personality traits increase the risk of addiction?

Personality Theory is the correct choice because it specifically addresses the role that individual personality traits play in the risk of developing addictive behaviors. This theory posits that certain traits, such as impulsivity, sensation-seeking, and a propensity for negative affectivity, can make an individual more vulnerable to addiction. By focusing on how intrinsic characteristics shape behavior and predisposition to substance use or addictive patterns, Personality Theory provides valuable insights into why some individuals may be more susceptible to addiction than others.

In contrast, the other theories mentioned focus on different aspects of behavior and treatment. Cognitive Behavioral Theory emphasizes the importance of thoughts and behaviors in the development of addiction but does not specifically highlight personality traits as risk factors. Psychodynamic Theory looks at underlying psychological processes and past experiences but does not hone in on personality traits in a direct way. Learning Theory centers on the role of environmental factors and learned behaviors in addiction, rather than inherent personality characteristics. Therefore, Personality Theory is the most relevant framework for understanding the link between personality traits and addiction risk.
