Which of the following is a direct measure of emotional well-being during health assessments?

A survey on mood serves as a direct measure of emotional well-being because it specifically assesses a person's feelings, emotions, and overall mental health. This type of survey can include questions about happiness, anxiety, and overall satisfaction with life, which are critical aspects of emotional well-being. By evaluating these factors, the survey provides immediate insight into a person's psychological state, allowing healthcare professionals to gauge mental health accurately and respond appropriately.

In contrast, income level, while it can have indirect effects on emotional well-being, does not directly measure how an individual feels or experiences their mental state. A physical health check assesses bodily functions and overall physical health but does not capture emotional or psychological aspects. Similarly, a dietary assessment focuses on nutritional habits and does not provide information about emotional health. Therefore, a mood survey is the most direct and relevant tool for evaluating emotional well-being.
