Checkmate Plus specializes in the publication of comprehensive assessment instruments designed to efficiently screen for the most prevalent DSM-5 emotional and behavioral disorders including attention-deficit/hyperactivity disorder (AD/HD). The Child Symptom Inventories are a series of parent and teacher checklists developed for the evaluation of three age groups (3 to 5, 5 to 12, and 12 to 18 years) to provide professionals with information about the presence of symptoms of at least a dozen DSM-5 disorders. There are also Symptom Inventories for adults. The checklists are used by professionals in mental health (psychologists, psychiatrists, social workers), education (school psychologists, special education personnel), and medical (pediatricians, neurologists) settings involved in the evaluation of emotional and behavioral problems. The Child Symptom Inventories were developed by Kenneth D. Gadow, Ph.D., Professor of Psychiatry and Special Education, and Joyce Sprafkin, Ph.D., Associate Professor of Psychiatry and Psychology. Drs. Gadow and Sprafkin are the authors of scores of scientific publications that cover a variety of topics in psychiatry, pediatrics, psychology, and special education. Their first symptom inventory was developed in 1984 to evaluate children with learning and behavioral disorders who were enrolled in special education programs.Later, this instrument was expanded to include the symptoms of more disorders and and adapted for use by clinicians. In 1994 the CSI were revised to reflect changes in diagnostic criteria and formatted for use with three different age groups (preschoolers, elementary school children, adolescents) and have now become widely adopted by professionals in mental health, medical, and educational settings.
