About Me

7M3A9781_4x6 copy.jpeg

Joseph Constans, PhD is a licensed clinical psychologist who has trained with some of the originators of cognitive-behavioral therapies including Drs. Andrew Mathews and Edna Foa.  Dr. Constans serves as the chief of research services at the New Orleans VA medical center, and he has his own federally-funded research program that concerns understanding and treating emotional disorders. 


His clinical services all involve non-medical interventions for emotional disorders and involve modification of behavior and/or cognitive factors that maintain the problematic emotional issues. 

Therapies offered by Dr. Constans are informed through his research activities and advocacy of evidence-based therapies for emotional disorders. Dr. Constans' expertise is best suited for those seeking treatment of anxiety disorders, mild to moderate depression, or general distress related to life stressors.

Contributions to Science

Understanding attention, judgment, and memory bias in pathological anxiety. Through the initial mentorship I received from Drs. Andrew Mathews and Edna Foa, I developed expertise in the study of cognitive bias associated with pathological anxiety. This scientific inquiry involved use of cognitive paradigms to understand how emotion impacts information processing, and in turn, how information processing bias furthers psychological distress. While I have studied attention, judgment, and memory bias, my primary interests have concerned appraisal bias. Most recently, my investigations have concerned developing strategies to modify biased appraisal.

Cognitive bias and neuropsychological deficits associated with PTSD. The majority of my research over the past 20 years has involved the study of attention, judgment, and memory in PTSD.  While our projects have focused on understanding cognitive and neuropsychological components of PTSD, my research interest has primarily concerned investigating how beliefs and information-processing biases that are present following trauma are associated with the development of trauma-related psychopathology. More recent efforts have concerned development of computer-based, cognitive-bias-modification programs designed to correct biases related to psychopathology.

Preventing violent death including homicide and suicide. My work in a level I trauma center led me to understand that, for many victims of community violence, the most pressing health issue was subsequent violent re-injury or gun violence perpetration, rather than solely development of PTSD. My work at the VA has impressed upon me the role of firearms in suicide deaths as approximately 70% of all Veteran suicides are due to guns. Therefore, for the past few years, I have been developing a treatment framework designed to understand and modify beliefs and behaviors associated with risky firearm behaviors as it relates to suicide and homicide.
