These researches focus on environmental psychology and terrorism

psychology. It is in the ICP Congress at Mexico that the author met Dr.

Roseline Davido, a French psychologist, creator of the assessment projective

test, the CHaD Test, which was published in United States, who

is also the President of the International Davido-CHaD. Thereafter, they

decided to develop a joint research on terrorism.

The objective of the research was to improve national security through

minimizing the level of Islamic radicalism among inmates in prisons and

detention houses as well as those who have been released. The research

subjects, who were ex-terrorists of Jamaah Islamiah (JI), used to refuse

any projective tests given to them, particularly written tests. However, the

CHaD test was the only assessment technique that was not refused and

was managed to be administered to the ex-terrorists. This book provides a

description of the joint research between Professor Sarlito and Dr. Davido.
