Which statement about prevalence is supported by the material?

• A. APD prevalence is higher in correctional samples and the community than psychopathy
• B. Psychopathy prevalence is higher than APD
• C. They are equal in prevalence
• D. Data are inconclusive

Answer: (A)

Prevalence differences stem from how each condition is defined and measured. APD is a DSM diagnosis that covers a broad pattern of antisocial behavior and disregard for rules across many life domains, including conduct disorder beginnings in adolescence. Because the criteria are wide, many people in both the community and correctional settings can meet APD criteria. Psychopathy, on the other hand, is a narrower personality construct typically assessed with the PCL-R, requiring high levels of both interpersonal/affective traits (like lack of empathy, superficial charm) and lifestyle/antisocial traits. Fewer individuals meet this higher, more specific threshold. So, across correctional samples and the general community, APD tends to be more prevalent than psychopathy, making the statement that APD prevalence is higher the best-supported one. The other possibilities clash with the reality that a broader diagnostic category yields more identifiable cases than the more selective psychopathy construct.
