American Art Therapy Association documenting its use as early as 1945. As with other sources of trauma, combat veterans may benefit from art therapy to access memories and to engage with treatment. A 2016 randomized control trial found that art therapy in conjunction with cognitive processing therapy (CPT) was more beneficial than CPT alone. Walter Reed Army Medical Center, the National Intrepid Center of Excellence and other Veteran Association institutions use art therapy to help veterans with PTSD. Bereavement A number of therapists use art therapy to assist those who have recently experienced the death of a loved one. This is proposed to be particularly beneficial where clients find it difficult to verbalize their feelings of loss and shock, and so may use creative means to express their feelings. For example, it has been used to enable children to express their feelings of loss where they may lack the maturity to verbalize their bereavement. Eating disorders Art therapy may help people with anorexia with weight improvements and may help with depression level. Traumatic or negative childhood experiences can result in unintentionally harmful coping mechanisms, such as eating disorders. As a result, clients may be cut off from their emotions, self-rejecting, and detached from their strengths. Art therapy may provide an outlet for exploring these inaccessible strengths and emotions; this is important because persons with eating disorders may not know how to vocalize their emotions. Art therapy may be beneficial for clients with eating disorders because clients can create visual representations with art material of progress made, represent alterations to the body, and provide a nonthreatening method of acting out impulses. Individuals with eating disorders tend to rely heavily on defense mechanisms to feel a sense of control; it is important that clients feel a sense of authority over their art products through freedom of expression and controllable art materials. Through controllable media, such as pencils, markers, and colored pencils, along with freedom of choice with the media, clients with eating disorders can create boundaries around unsettling themes. Another systematic literature review found conclusive evidence that art therapy resulted in significant weight loss in patients with obesity, as well as helping with a range of psychological symptoms. Ongoing daily challenges Those who do not have a mental illness or physical disease were also tested; these patients have ongoing daily challenges such as high-intensity jobs, financial constraints, and other personal issues.
