Mohiuddin Ahmed, Ph.D.

Mohiuddin Ahmed is a Licensed Psychologist Provider in Massachusetts and Rhode Island who obtained his Ph.D in clinical psychology from University of Pittsburgh, and M.Sc. in clinical psychology from Long Island University in Brooklyn, New York as a Fulbright Scholar from Bangladesh, where he also obtained M.A., and BA (Hons.) in Philosophy from Dhaka University. He completed his clinical internship at the Winnebago Mental Health Institute in Wisconsin, and has been involved in providing psychological and consultation services for over 45 years of associations with inpatient facilities (Wrentham Developmental Center, Taunton State Hospital), and outpatient programs at several Community Mental Health Centers (Community Care Alliance RI in Woonsocket, Community Counseling Center in Pawtucket, and Versa Care, Inc. in Attleboro, and other agencies) and through his private practice work in RI and Massachusetts. He was associated with several educational collaborative agencies in Rhode Island and Massachusetts, such as BICO Educational Collaborative, Northern Rhode Island (NRI) Collaborative, South Shore Educational Collaborative to provide behavioral and educational assessments of children and youths, as well as providing 2nd Opinion consultations on Individual Educational Plans (IEP). He also has experience in conducting functional behavior assessments using applied behavior principles for developmentally disabled adults in community residences through NRI Youth and Family Collaborative in Pawtucket, RI, and has also worked for several years in nursing homes, providing psychological services, while being associated with Med Options, Inc. Besides providing individual, group, and family therapy and psychological and behavioral assessments and consultations, he has been involved in many innovative clinical service program developments : he was part of a pioneering project involving “home based” counseling and school based counseling, and day educational program as alternative education for “behaviorally disordered” children and youths through collaborative partnership relationship involving NRI Community Center and Local Educational Authorities (public schools in its catchment areas). He has published work involving computer-facilitated dialogue with adults and adolescents in psychiatric inpatients and outpatient settings, and pioneered Mind Stimulation Therapy through his work with various clinical populations, such as behaviorally disordered children, adults with severe and persistent mental illness, (i.e. Schizophrenia), dual diagnosed substance abuse clients, and psychiatrically disabled geriatric clients in nursing home settings, and published a book and many articles in collaboration with his former student, currently a professor at Rhode Island College, Dr. Charles Boisvert. Dr. Ahmed maintained through his extensive work experience in public service facilities as full-time and subsequently part-time positions in those facilities, an active private practice work while being either associated with Human Resource Institute in Franklin, or in his private practice offices in RI and Massachusetts providing psychotherapy services to children, adolescents, adults, and families. He also has years of teaching experience while involved with Dhaka University in Bangladesh, Ateneo De Manila University in the Philippines, and Northeastern University in Boston, and mentoring of Ph.D. and Master’s degree students in clinical, counseling, and school psychology, and mental health counseling through their internship and externship placements at Taunton State Hospital, NRI Community Services, Versa Care Inc., and as Adjunct Professor in the Clinical Psychology Department of University of Rhode Island.

Currently Dr. Ahmed is associated with Metis Psychological Associates, LLC to provide individual, group, and family psychotherapy, and behavioral consultation to parents and Public Schools, and is a consultant to Community Care Alliance RI in Woonsocket where he provides consultation on functional evaluation reports using Applied Behavior Analysis and training for clinical program staff on application of Mind Stimulation Therapy that he pioneered; in their children, adolescent, and adult service programs. He is also an Adjunct Professor in the Department of School Psychology and Counseling and Educational Leadership at Rhode Island College.

Dr. Ahmed takes the approach that as human beings, all our experiences involve information processing, regardless of age and life circumstances. In our own individual ways, we are all trying to figure out what is going on with our lives in the present moments of our existence. All psychological maladies can be viewed as expressions of some form of personal existential crisis to our perceived experience of stress in our lives. As a result, we may engage in a particular form of thinking, feeling, and behaving that happens to cause distress and interfere with our everyday functioning. Success in therapy involves a collaborative dialogue to stimulate client’s mind to promote personal well-being, as well as for the family. Dr. Ahmed believes in collaborative dialogue to promote reflective thinking about one’s personal goal, barriers to goals, and steps to reach goals. In the goal development process, he has used visual representation through computer-facilitated dialogue that he pioneered for effective communication, and for more effective follow-through for clients to remember what was discussed in the sessions. He also uses a variety of mind stimulation techniques that may involve body-movement-relaxation, cognitive stimulation, mental health coping strategies, and existential perspectives to promote adaptive thinking and personal welfare.
