For much of the 1920s and 1930s, Hubbard lived in Washington D.C., and he would later claim to have interacted with multiple psychiatrists in the city. [22] Hubbard described encounters in 1923 and 1930 with navy psychiatrist Joseph Thompson. [23] [24] Thompson was controversial within the American psychiatric community for his support of lay analysis, the practice of psychoanalysis by those without medical degrees. Hubbard also recalled interacting with William Alanson White, supervisor of the D.C. psychiatric hospital St. Elizabeth's. [25] [26] [27] According to Hubbard, both White and Thompson had regarded his athleticism and disinterest in psychology as signs of a good prognosis. [28] Hubbard later claimed to have been trained by both Thompson and White. [29] Hubbard also discussed his interactions at Chestnut Lodge, a D.C.-area facility specializing in schizophrenia, repeatedly complaining that their staff misdiagnosed an unnamed individual with the condition:Defections, court fights test Scientology".

Like Freud, Hubbard taught that the brain recorded memories (or "engrams") which were stored in the unconscious mind (which Hubbbard restyled "the reactive mind"). Past memories could be triggered later in life, causing psychological, emotional, or even physical problems. By sharing their memories with a friendly listener (or " auditor"), a person could overcome their past pain and thus cure themselves. Through Dianetics, Hubbard claimed that most illnesses were psychosomatic and caused by engrams, including arthritis, dermatitis, allergies, asthma, coronary difficulties, eye trouble, bursitis, ulcers, sinusitis and migraine headaches. He further claimed that dianetic therapy could treat these illnesses, and also included cancer and diabetes as conditions that Dianetic research was focused on.

After trying and failing for two years to regain my equilibrium in civil life, I am utterly unable to approach anything like my own competence. My last physician informed me that it might be very helpful if I were to be examined and perhaps treated psychiatrically or even by a psychoanalyst. Toward the end of my service I avoided out of pride any mental examinations, hoping that time would balance a mind which I had every reason to suppose was seriously affected. I cannot account for nor rise above long periods of moroseness and suicidal inclinations, and have newly come to realize that I must first triumph above this before I can hope to rehabilitate myself at all. ...

Owen argues that Hubbard likely suffered from venereal disease, writing: "Sulfa drugs were used in treatment but in excess could cause bloody urine, something which Hubbard's shipmate Thomas Moulton saw him passing on at least one occasion. Hubbard himself later complained about the amount of sulfa he had been fed in the Navy. Former Scientology spokesman Robert Vaughn Young claims that Hubbard's private papers refer to him having caught gonorrhoea from a girlfriend named Fern, which forced him to secretly take sulfa."The kid’s group has been so successful. We’ve heard from the parents and caregivers how it’s helped them. Talking about the caregivers, we also have a group for caregivers. There are a lot of times when a parent or family member is taken into the prison system, and the kids might not have somebody to take care of them. They might go to a grandmother, aunt, uncle, another family member or even go into foster care. The caregivers’ group is important. Neela, can you tell us a little bit about that group?
