The American Psychiatric Association (APA) has completed a decade-long process and approved changes to its diagnostic manual. The goal for the DSM-5 is to make the process as scientifically valid as possible but Temple professor Frank Farley says even though it’s an improvement, it’s not completely successful. “Significant decisions are made about people in the courts, in the mental health system and with insurers so we want it to be absolutely impeccable ... some of these (changes) are not particularly solid science.”
