Henk Rigter, PhD

Rigter studied psychology at the University of Nijmegen, the Netherlands, from 1965 to 1971, and pharmacology at the University of Utrecht, from 1970-1973.

He specialized in neuroscience and psychopharmacology and wrote a PhD thesis on amnesia. After having led a laboratory in the pharmaceutical industry for 10 years, he took a position with the Netherlands Council for Science Policy, advising the government on priorities to be set in health (biomedical, clinical, and health services) sciences in the Netherlands. In 1983, he was appointed director of the Health Council of the Netherlands, an advisory body issuing reports on which the Netherlands government often bases its policy decisions. In 1989, Rigter was appointed professor in "social aspects of medical technology" at the Erasmus University (Medical School) in Rotterdam, the Netherlands.

In January 1993, Rigter took the position of director of the Netherlands Institute of Mental Health in Utrecht. After a merger in September 1996, this institute is now called Trimbos Institute (Netherlands Institute of Mental Health and Addiction). Rigter was general director of this 200-staff research and documentation centre until February 2003.

He is still associated with the Erasmus University (Department of Public Health) but presently also with Curium (Department of Child and Adolescent Psychiatry, Leiden University Medical Centre), where he is in charge of national and international (Belgium, Germany, France, the Netherlands, Switzerland, USA) research and implementation projects in the field of treating adolescents with (multiple) problem behavior. One of the transnational research projects has been INCANT, a randomized trial comparing MDFT (Multidimensional Family Therapy) with active comparison treatment in adolescents with cannabis use disorder.

Rigter has served as a member or chair on numerous national and international (advisory) committees devoted to science and social policy, ethics, technology assessment, neuroscience, and mental health. For 15 years, he has been the Chair of the Population Screening Committee, which advises the Dutch Government from a scientific point of view on permits to be granted to or to be withheld from parties and organizations wishing to implement screening programs for instance in the field of cancer or genetics. This work involves very thorough ethical, legal, medical, psychological, and social assessments, and evaluation of health claims. The Committee helps in improving proposals. Its role is constructive, rather than just critical.


Cynthia Rowe, PhD

Research Associate Professor of Epidemiology and Public Health at the University of Miami Miller School of Medicine’s Center for Treatment Research on Adolescent Drug Abuse (CTRADA). Dr. Rowe received her PhD in clinical psychology from Temple University. Since 1994, she has been instrumental to the Center’s work, focusing largely on refining, testing, and disseminating family-based interventions for adolescents with emotional and behavioral problems, delinquency, and substance abuse.

An MDFT trainer, Dr. Rowe works actively with her colleagues to promote the translation of research findings into practice, and to train providers throughout the U.S. and in other countries to implement Multidimensional Family Therapy (MDFT) in diverse clinical settings. She is currently PI of a grant from NIAAA to conduct a randomized clinical trial of two innovative family interventions for youth identified with alcohol problems in the emergency department. She has also been PI and Co-PI of several NIDA grants, including the Florida Research Center of NIDA’s CJDATS collaborative, which tested an innovative cross-systems version of MDFT with integrated HIV prevention delivered to youth in detention and as they transitioned home. Dr. Rowe was also integrally involved in the research and clinical activities of a multisite randomized controlled trial of MDFT in five countries in Western Europe.

She has been a regular reviewer of health services research grants with NIDA and NIH since 2006 and has authored peer-reviewed research articles, clinical publications, and book chapters. She also co-edited Adolescent Substance Abuse (2006, Cambridge University Press), a comprehensive volume dedicated to treatment research on adolescent substance abuse.
