Special Externship in Empirically Supported Treatments: Emphasis on Organizational Skills Treatment for ADHD or Selective Mutism Treatment

Special Externship in Empirically Supported Treatments: Emphasis on Organizational Skills Treatment for ADHD or Selective Mutism Treatment

The Child Study Center seeks graduate students to complete a year-long externship in empirically supported treatments. There will be extern positions available at our New Jersey office, located in Hackensack, New Jersey and at our New York City campus, located near the main campus of NYU Langone Medical Center. Richard Gallagher, PhD, director of projects within the Institute for Attention Deficit Hyperactivity and Behavior Disorders and the Selective Mutism Program and the person primarily responsible for creating the interventions, will coordinate all supervision for these externships.

The number of Externships available is as follows:
New Jersey Campus: 2 externs
New York City Campus: 2 externs

Clinical Responsibilities:

  • Behavioral Psychotherapy: All externs will be involved in providing two clinical interventions created and advanced at the Child Study Center. Externs will learn and deliver Organizational Skills Treatment for children with ADHD through a clinical research study. Currently, training in this treatment is available only at the CSC. This program is for children enrolled in elementary school. Extensions of this intervention for older students are also provided. Externs will also learn to deliver treatment for selective mutism, primarily for young children. Both interventions involve extensive opportunities to work with individual children, their families, and professionals in their schools.
  • Evaluation and Testing: The positions incorporate psycho-diagnostic and neuropsychological evaluations. Patient populations include persons with anxiety disorders; ADHD with comorbid learning problems; and learning disorders. Externs will participate in intakes and feedback relevant to these testing cases.
  • Seminars/Didactics: Externs are welcome to attend seminars and case conferences held at the Child Study Center locations.
  • School Visits: Externs are invited to attend monthly school visits in which we are educated about specialized programs throughout the city. Opportunities for classroom observations to supplement the clinical evaluation may also be available.

Non-Clinical Responsibilities:

  • Weekly individual and group supervision for cases
  • Possible attendance at weekly Case Conference
  • Possible attendance at weekly Grand Rounds (Fridays 11 a.m.–12:15 p.m.)
  • Participation in seminars and other education opportunities


The extern will receive training in cognitive-behavioral case conceptualization. With the guidance and support of a staff psychologist, the extern will prepare a case presentation to present at a team meeting. Case presentations usually consist of a conceptualization, brief literature review, and overview of the treatment approach. This practice exercise aims to help prepare students for the advanced training requirements of internship. Externs can also assist in presentations given to the NYU academic community, as well as to local community organizations and professional groups.

Research (optional):

Opportunities may arise for externs to participate in clinical research projects that are being conducted by staff psychologists.

Time Requirement:

Two full days per week will be required. For each office, the extern must arrange a schedule that conforms to one of the following options: Monday and Wednesday, Monday and Thursday, Tuesday and Thursday, Tuesday and Friday, or Wednesday and Friday. One of these schedules is required in order to deliver the Organizational Skills Training Program.

Contact Information:

Those interested in applying should submit a letter of interest, writing sample (intake report preferred), attestation letter from your graduate program stating your eligibility for externship, two to three letters of recommendation (from professors or clinical supervisors) and CV via our online application. Please note if you are interested in applying to more than one externship within the Child Study Center, you must submit an application to each externship separately. The applicant should also forward a list of tests divided into three categories: (1) those that can be administered proficiently, (2) those that the applicant has some experience with, but requires more training, and (3) those that the applicant has no experience with but would like to learn about if possible. Please contact Richard Gallagher, PhD at with questions.
