Psychological effects refer to the impact that various factors or experiences can have on an individual's mental and emotional well-being. This can include the effects of trauma, stress, social relationships, mental health disorders, and other factors that can influence a person's thoughts, feelings, and behaviors. Research in this area aims to better understand how these psychological effects manifest, how they can be measured or assessed, and how they can be addressed or treated in order to promote mental health and well-being.
