Abstract
A prevailing view among researchers and mental health clinicians is that symptoms of antisocial personality disorder (ASPD)/psychopathy decrease as affected individuals reach middle age. In the current investigation, informants were surveyed about the behavior of individuals who they believed showed traits of ASPD/psychopathy and were over the age of 50. A final sample of 1,215 respondents rated the index individuals according to the ASPD/psychopathy traits derived from the pre-publication first draft of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition, revealing high endorsement of traits associated with ASPD. Survey respondents reported their observations that individuals who met a threshold for putative ASPD/psychopathy continued to engage in antisocial behavior after age 50, and as a result the respondents endured significant harm, including material losses, financial losses, and various self-reported mental health problems. Those who knew the index individuals both before and after the age of 50 were specifically asked whether there was a change in the individual’s engagement in manipulation, deceit, and antisocial behavior; 93% of respondents reported that the behavior was just as bad or worse after age 50. Other researchers have suggested that the DSM diagnostic criteria do not accurately describe ASPD/psychopathy symptoms and behavior in older adults, and that the disorder remains stable, but its manifestation changes with age. This study supports those conclusions.
