Which negative symptom refers to a decrease in self-initiated purposeful activities?

Avolition is identified as a negative symptom in schizophrenia that involves a significant decrease in self-initiated purposeful activities. Individuals experiencing avolition may show diminished motivation to engage in activities that were previously important or pleasurable, reflecting an overall lack of drive or initiative. This can manifest in various areas, such as neglecting personal care, failing to follow through with work or social obligations, or showing disinterest in hobbies.

Understanding avolition is essential as it distinguishes it from other negative symptoms. For instance, while anhedonia refers specifically to a loss of pleasure or interest in activities, and asociality relates to the lack of interest in social interactions, avolition focuses on the reduction of intentional actions and goals. This distinction highlights how affected individuals may have the desire or interest but are unable to mobilize themselves towards action. Alogia, on the other hand, specifically refers to a decrease in speech output, thus not capturing the essence of decreased initiative in activities.

Recognizing avolition as a key symptom helps in both diagnosis and tailoring interventions to support individuals in increasing their engagement in necessary and meaningful activities.
