The "Bastiaans method" (treating traumatized adults with a concentration camp syndrome with LSD or pentothal) was supposed to make patients relive their war and Holocaust past.
Eibert lied --perhaps in the context of pseudologia phantastica-- about a resistance past and Bastiaans did not realize that his patient was making up events.
During the 1970s, Bastiaans also began to apply his insights about traumas to other groups of traumatized people, including victims of torture, incest and traffic accidents.
In terrorist attacks such as the train hijacking in Wijster in Drenthe and the hostage taking of the staff of the Indonesian consulate in Amsterdam by Moluccan youths, he provided the media with commentary on the events.
Bastiaans published a book about this in 1979 under the title Psychologisch onderzoek naar de gevolgen van gijzelingen in Nederland (1974–1977) [Psychological research into the consequences of hostage taking in the Netherlands (1974–1977)] .
Although he became increasingly isolated in the medical world, he was always supported by an intensive lobby from the former resistance and by his contacts at the Dutch court, in particular with Prince Bernhard.
This made it virtually impossible for the Executive Board to impose restrictions on him, despite growing doubts about his way of working at the ministry and at the Health Inspectorate.
His departure as director of the Jelgersma Clinic on 31 December 1982 — he had to retire because he had turned 65 — led to many problems because, despite earlier agreements, he refused to leave voluntarily, and he continued to use his villa in his capacity as professor for admissions and treatments.
Despite all objections, the resistance organizations managed to get the Lower House of the Dutch parliament to adopt a motion at the end of March 1985 that determined that Bastiaans should be able to continue his work after his departure as professor on June1, 1985, and on June 28, 1985 he gave his farewell lecture.
