The most effective method for diagnosing a patient with a history of authority issues and a lack of regret for actions is to thoroughly assess the patient's history. This approach allows for a comprehensive understanding of the individual’s past behaviors, patterns, and interpersonal relationships. Given the context of the question, it implies a potential personality disorder or antisocial traits, where a detailed exploration of the patient’s life circumstances, choices, and reactions to authority figures can provide critical insights.

When examining the patient’s history, clinicians can gather valuable information regarding their developmental background, significant life events, relationships, and behavioral responses over time. This historical perspective is crucial in identifying the patterns associated with certain disorders, such as antisocial personality disorder or traits associated with psychopathy.

While other diagnostic tools, such as the psychopathy checklist or personality inventories, can provide additional information, they are often used to support or augment a well-established clinical picture formed through an in-depth evaluation of the patient's history. Essentially, these tools alone cannot replace the contextual understanding obtained from the patient’s comprehensive background.

Therefore, relying on the patient’s history as the primary means of diagnosis aids in creating a holistic understanding of their behavior and personality, making it the best initial approach in this scenario.
