Linda Pfiffner, PhD
Linda Pfiffner, PhD, is a professor and director of the Hyperactivity, Attention and Learning Problems (HALP) Program in the Department of Psychiatry, and is a licensed clinical psychologist. She received her BA from UCLA and her PhD from the State University of New York at Stony Brook. Prior to joining UCSF in 2001, she held academic appointments at UC Irvine and the University of Chicago. Her program of research centers on the development and evaluation of collaborative school-home psychosocial treatments for school-aged children with ADHD, the inattentive presentation of ADHD, and family/social factors in developmental models of ADHD and related problems. She has over 190 refereed articles, chapters, and scientific conference abstracts and has published a second edition to her handbook for teachers “All About ADHD: The Complete Practical Guide for Classroom Teachers” (Scholastic, 2011). For the past 25 years, her research has been supported by multiple grants from the National Institute for Mental Health (NIMH) and Institute of Education Sciences (IES).
She developed the Child Life and Attention Skills (CLAS) Program, an integrated multi-component behavioral intervention for children with ADHD-inattentive presentation. CLAS has been evaluated in two NIMH-funded randomized controlled trials, one being a dual-site study, with positive effects on inattention symptoms and impairments. The program was awarded Innovative Program of the Year in 2004 by Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD). She and her team adapted the program for youth with attention and behavioral concerns, developing the Collaborative Life Skills Program (CLS) for delivery by school-based mental health professionals in school settings. A recently completed IES-funded randomized controlled trial shows significant treatment-related improvement on children’s ADHD symptoms, behavior, and academic and social functioning. She is currently developing a web-based, remote training program for school mental health providers in implementation of CLS with funding from IES.
Dr. Pfiffner also serves as director of the Clifford Attkisson Clinical Services Research Training Program, an NIMH-funded T32 which provides education and support to postdoctoral scholars from a variety of disciplines who plan to pursue careers in mental health services research. She serves on multiple editorial boards of leading psychology journals, was a former standing member of the NIMH Interventions Committee for Disorders Involving Children and Their Families Initial Review Group study section and a principal member of the IES Social and Behavioral Education Research Scientific Review Panel. She frequently lectures and leads workshops about ADHD for mental health professionals, teachers and parents. Dr. Pfiffner was inducted into the CHADD Hall of Fame in 2012.

Pevitr S. Bansal, MS
Pev Bansal is a predoctoral clinical psychology fellow. He received his BA in psychology from Penn State Abington and his MS in counseling and clinical health psychology from the Philadelphia College of Osteopathic Medicine. He is completing his PhD in clinical psychology at the University of Kentucky under the mentorship of Dr. Michelle Martel.
Pev’s line of research focuses on the etiology and treatment of conduct problems (CP; e.g., defiance, aggression) with a particular interest in the role of affect (e.g., irritability, callous-unemotional traits). His work examines how these affective traits – particularly callousness – relate to the development of CP, while also exploring the unique associations between affect and intervention effects for youth with CP. Ultimately, Pev aims to bridge the gap between etiology and treatment to (a) develop more accurate assessments for CP and (b) design more effective and personalized treatments to target the mechanisms – such as emotion dysregulation or reduced empathy/guilt – that underlie aggressive and disruptive behaviors.
In the HALP clinic, Pev works under the mentorship of Dr. Linda Pfiffner to continue examining treatment effects for youth with ADHD and related disruptive behavior disorders. He also conducts comprehensive evaluations and group-based treatments for children with ADHD and their families.
