Validity:Validity refers to how accurately an assessment measures what it intends to measure. In the context of psychiatric diagnoses, validity determines if the diagnosis actually reflects the individual's mental health condition.
Labeling theory: Labeling theory suggests that once individuals are labeled with a particular diagnosis, they may experience stigmatization and be treated differently by society or even themselves.
Confirmation bias: Confirmation bias occurs when people seek out or interpret information in a way that confirms their preexisting beliefs or expectations. In terms of psychiatric diagnoses, confirmation bias could lead clinicians to overlook contradictory evidence and only focus on confirming their initial diagnostic impression.
