Difference Between Mood and Affect In Psychiatry

Difference between Mood and Affect in Psychiatry: In psychiatry, Mood and Affect are different yet interconnected concepts used to evaluate a person's emotional state. Mood refers to the internal, subjective experience of emotions that persist over time, characterised as positive, negative, or neutral. It encompasses feelings such as happiness, sadness, anxiety, or irritability and can last for varying durations, from hours to weeks. In contrast, Affect pertains to the outward expression of emotions through facial expressions, gestures, and tone of voice. It serves as an observable manifestation of Mood, providing insight into a person's emotional responsiveness and regulation. Understanding both Mood and Affect is crucial in psychiatric assessment as changes in either may indicate underlying mental health issues.
