Psychodiagnostics - Ridgewood, New Jersey

Welcome to Psychodiagnostics, a private practice specializing in psychological assessment.  We measure personality, intelligence, academics and symptoms with professional and reliable instruments.  Descriptions, conclusions and formal diagnoses are carefully formed through observation, history and comprehensive assessments. 

Psychodiagnostics attempts to answer all referral questions. We focus on the area of concern, while also screening other areas for potential weaknesses.   In this way, we describe weaknesses, while ruling out alternative explanations.  It is our goal to answer your question.  Our assessments can discriminate between normal experience and clinical pathology, personality variation and personality disorders, attention deficit hyperactivity disorder and other causes of inattention, specific learning problems and global intellectual delays.  We can differentiate between disorders, describe disorders or explain them.  In addition, our staff can recommend treatment plans and answer questions through assessment or consultation. Psychodiagnostics serves New Jersey and New York residents and families.  We also offer individually arranged assessments and ongoing contracts to psychological and psychiatric practices, schools and agencies.
