Which of the following is a psychological adverse effect of androgenic anabolic steroids?

Extreme aggression is identified as a psychological adverse effect of androgenic anabolic steroids due to how these substances can influence mood and behavior. Anabolic steroids can disturb an individual's emotional state, often leading to what is commonly referred to as "roid rage," which manifests as heightened aggression, irritability, and even violent outbursts.

This aggressive behavior stems from the hormonal changes induced by the steroids, as they can affect neurotransmitters in the brain that regulate mood and behavior. Users might find themselves experiencing heightened levels of anger or confrontational behavior, which are significant psychological risks associated with steroid use.

In contrast, increased self-confidence, while it may be experienced by some users, is not considered a negative psychological effect in this context. Improved mood stability and decreased anxiety are also typically not linked to the adverse psychological effects of anabolic steroid use. Instead, users often report mood swings and increased levels of anxiety, rather than a reduction in those feelings. Thus, extreme aggression accurately reflects a serious psychological consequence of anabolic steroid use.
