A second psychologist took the stand in Johnny Depp's defamation trial against ex-wife Amber Heard to refute the analysis of the previous psychologist's testimony.

Dr. Dawn Hughes, a clinical and forensic psychologist, testified Tuesday that Heard showed a moderate degree of post-traumatic stress disorder but no signs of borderline personality disorder, unlike the previous statements from psychologist Dr. Shannon Curry.

"Ms. Heard demonstrated psychological and traumatic effects," Hughes said after spending a total of 20 hours with Heard from September 2019 to December 2021.

Hughes subjected the actress to 12 total tests, including a personality assessment, trauma inventory, a mood disorder questionnaire, and a conflict tactics and danger assessment scale. The psychologist also testified that she approached each evaluation "with a healthy dose of skepticism" but found no evidence of Heard "malingering," or feigning, symptoms. Heard's mother, Paige Parsons Heard, was also interviewed by Hughes shortly before she died in 2020.

As a result, Hughes also said she saw signs "consistent with what we know in the field as intimate partner violence" in Amber Heard's relationship with Depp based on what Amber Heard reported alone. Hughes discussed Depp allegedly subjecting Amber Heard to cavity searches for cocaine in her vagina, controlling what she wore, accusing her of flirting with men and women, and calling her names such as whore, c***, and "lesbian camp counselor."

While Curry used the Clinician-Administered PTSD Scale, which is the "gold standard," according to the National Center for PTSD, to determine that Amber Heard did not have PTSD, Hughes used the same CAPS assessment and found the opposite. She went on to claim that after 20 years in the field, she'd administered hundreds of assessments. Hughes also administered the Minnesota Multiphasic Personality Inventory-2 to find that Amber Heard did not have a personality disorder, while Curry gave the opposite diagnosis using the same assessment.

"I didn't agree with her evaluation," Hughes said of Curry.

Despite their differences, Amber Heard's lawyer, Elaine Bredehoft, mistakenly called Hughes "Dr. Curry" a number of times throughout her testimony. Curry was in the gallery during the trial Tuesday, which disqualifies her from being called to the stand again.

Hughes referred to Depp's testimony, seemingly unintentionally, when he questioned why Amber Heard would stay with him if she was afraid. Hughes claimed it is a "myth" that women who are abused will leave, saying instead they often stay.

Regarding allegations that Amber Heard was violent with Depp, Hughes claimed it is common among abused women to fight back either with violence or name-calling. Amber Heard reportedly felt sorry for the things she'd said to her ex-husband, according to sessions with Hughes.

Hughes also confirmed that substance abuse, something Depp has been accused of, "doesn't cause people to be violent."
