Additional Details

Does your student meet the IDEA criteria for emotional disturbance?

The EDDT helps you determine qualification for special education services under the category of emotional disturbance by assessing from the teacher, parent, and students’ perspectives. It is the first instrument of its kind to provide a standardized approach to the assessment of emotional disturbance (ED). It is a standardized, norm-referenced assessment designed to assist in the identification of children who qualify for the federal special education category of ED. The EDDT addresses the broad emotional and behavioral nuances of children who may require special education services for ED.

Introducing the consolidated EDDT!

The EDDT materials have been completely redesigned and streamlined to make your assessment experience easier.

  • All three forms (Parent, Teacher, and Self-Report) are now addressed in one manual.
  • PARiConnect purchasing is easier than ever. Choose which form to administer and/or which report to generate after you purchase.
  • Score exclusively via PARiConnect—no more hand-scoring means there are no scoring forms or profile forms to purchase.  
  • Administer via PARiConnect or use paper forms that combine the item booklet with the response booklet.
  • For your convenience, administration and scoring have been bundled—so you have fewer components to buy.
  • Already own EDDT materials? Existing materials may continue to be used until it’s time to purchase more. With any new purchases, you will begin to use digital scoring. See the FAQ section below for information on using your current inventory of print and digital components.

Features and benefits

  • The EDDT is based on the criteria presented in the Individuals with Disabilities Education Improvement Act of 2004 (IDEA) with scales that map directly onto these criteria.
    • Inability to Build or Maintain Relationships
    • Inappropriate Behaviors or Feelings
    • Pervasive Mood/Depression
    • Physical Symptoms or Fears
  • The EDDT offers school/clinical professionals a standardized approach to the assessment of ED that encompasses the federal guidelines and addresses the broad emotional and behavioral nuances of this population. It accomplishes this by providing scales for both the inclusionary and exclusionary criteria covered in the federal criteria.
  • From the U.S. Code of Federal Regulations (2002) and the reauthorization of IDEA (2004), the federal criteria mandate that certain conditions be present in order to receive services but don’t provide assessment guidelines. The EDDT includes five sections that correlate with the specific components of the federal criteria, enabling you to work through each criterion one by one.
  • Provides powerful norm-based data for the assessment of ED. Specifically, it provides data on the federal ED criteria as well as valuable information about social maladjustment, severity, possible ADHD, possible psychosis, and student strengths.
  • The Teacher and Parent forms may be used with students ages 5 to 18 years; the Self-Report Form is designed for students ages 9 to 18 years.
  • Both Parent and Self-Report forms are available in Spanish.
  • The EDDT treats social maladjustment as a supplemental trait and assesses it separately from ED. This is helpful if your state specifies that socially maladjusted children can’t qualify for services unless they are both socially maladjusted and emotionally disturbed.
  • The Multirater Summary Report, available for free, can be used to review results from multiple raters to create a well-rounded picture of an individual's functioning.

Test components

  • Manual. Information from the Teacher, Parent, and Self-Report forms are combined into one manual, available in print or as an e-Manual. 
  • Print administration. For each form, the item booklet and answer sheet are combined into one printed form that facilitates response entry into PARiConnect. Print forms are bundled with score reports, so one purchase gets you everything you need for print administration and digital scoring.
  • Digital administration. Purchase an EDDT i-Admin/Score Report bundle. Then once you are in PARiConnect, choose which of the five forms you want to administer: Teacher, Parent, Parent Spanish, Self-Report, or Self-Report Spanish.
  • Scoring. All scoring is done via PARiConnect, whether you administer via paper or digitally. As always, the Multirater Summary Report is free to generate after at least two score reports have been generated for the same individual.
  • Kits. To allow you to purchase everything you need at once, print administration (both English and Spanish) and digital administration kits are available.

FAQs

I already own one of the original professional manuals. Can I still use it, or do I need to buy the new combined manual? 

If you purchased any manual prior to August 2024 (teacher, parent and/or self-report), you may continue to use it. If you prefer the convenience of having all three forms covered in one manual, or are a new user, we suggest purchasing the new print manual or e-Manual.

What do I do with my current inventory of printed test components? Can I still use them?

If you already own these printed EDDT materials, you may keep using them until it’s time to purchase more.

  • Multi-Rater Summary Forms (11116-RF)
  • Response Booklets (6008-RF, 6846-RF, 11111-RF)
  • Reusable Item Booklets (6009-TB, 6847-TB, 11112-TB)
  • Score Summary Booklets (6010-SF, 6848-SF, 11113-SF)
  • Spanish Reusable Item Booklets (6850-TB, 11115-TB)
  • Spanish Response Booklets (6849-RF, 11114-RF)

For future orders, the Response Booklet (answer sheet) and the Item Booklet will be replaced by the applicable printed form (Teacher, Parent, Self-Report, Parent Self-Report, Spanish Self-Report) plus a Score Report. The Multirater Summary Report, available for free, can be used to review results from multiple raters. For those with existing forms who need additional Score Reports, contact Customer Support.

What happened with my PARiConnect inventory and reports that I already ran?

In August 2024, the EDDT materials were streamlined to make your assessment experience easier, with all three forms (Parent, Teacher, and Self-Report) being addressed in one manual and a single i-Admin/Score Report. Your existing digital inventory was automatically moved at launch.

Specifically, all unused inventory for the five EDDT i-Admins (Teacher: 10518-IC, Parent: 10520-IC, Spanish Parent: 12030-IC, Self-Report: 11434-IC, Spanish Self-Report: 12031-IC) was moved to a single new i-Admin item number, and all unused inventory for the three Score Reports (Teacher: 10519-IS, Parent: 10521-IS, Self-Report: 11435-IS) was moved to a single new Score Report item number. For future orders, purchase the EDDT i-Admin/Score Report (12270-IK).

Previously generated reports and exports are still available and able to be regenerated. In-progress i-Admins, manual entry forms, and unscored reports are unaffected.

To see your inventory, log into PARiConnect and select View Inventory.  Your screen will look like this:

 

What is new about administering the EDDT on PARiConnect?

here are a number of enhancements to help streamline your administration. Going forward you purchase an i-Admin/Score Report bundle.  Once you are logged into PARiConnect, you then choose which form to administer and which report to generate. The Multirater Summary Report remains free and is generated after at least two score reports have been generated for the same individual. All scoring is now done on PARiConnect. No more hand scoring.

Here is how you select which form to administer in PARiConnect.

What is the test structure of the EDDT?

  • The Teacher Form asks the rater to respond to items in five sections, one using yes/no style, one using Likert style, and three using multiple-choice style. The Parent and Self-Report forms ask raters to respond in Likert style to 185 and 136 items, respectively.
  • Emotional Disturbance characteristics scales include Inability to Build or Maintain Relationships, Inappropriate Behaviors or Feelings, Pervasive Mood/Depression, and Physical Symptoms or Fears.
  • Screening items are included on the Attention-Deficit Hyperactivity Disorder, Possible Psychosis/Schizophrenia, and Social Maladjustment clusters.
  • Level of Severity and Educational Impact (Teacher Form only) clusters address how emotional and behavioral problems affect students and aid in the development of recommendations and interventions.
  • A Motivation cluster and a Resilience scale measure student strengths, allowing the rater to communicate positive information about the student and helping guide intervention so you can develop appropriate recommendations.
  • Generate the Multirater Summary Report to review results from multiple raters (teacher, parent, and self-report) to create a well-rounded picture of an individual's functioning.

What is the technical information for the EDDT Teacher Form?

Norms are based on a sample of 601 children who were demographically matched to U.S. Census statistics. Data were also collected on a sample of 404 children eligible for special education due to an ED diagnosis.

Internal consistency was high (r = .94) for the EDDT Total Score and ranged from .75 to .88 for the scales. In addition, test-retest stability was high (r = .92) and interrater reliability was good (r = .84) for the EDDT Total Score.

Convergent validity was examined using the CAB Teacher and Parent Forms, the BASC-2 Teacher Form, and the Teacher Report Form of the CBCL. Validity also was examined in populations of children with specific learning disabilities, speech/language impairment, mental retardation, ADHD, autism spectrum disorder, and social maladjustment.

What is the technical information for the EDDT Parent Form?

The normative sample of 889 children was well matched to U.S. Census statistics. In addition, data were collected on a sample of 430 children eligible for special education due to an ED diagnosis.

Internal consistency was high for scales (median r = .81) and clusters (median r = .91), test-retest reliability was high for scales (median r = .95) and clusters (median r = .96), and interrater reliability was good (r = .87) for the total score.

Convergent validity was examined with the BASC 2 PRS, Conners Parent Scale, CDS, DTCEP, and PBRS. Validity was also examined among children with various special education needs, ADHD, social maladjustment, and psychosis.

What is the technical information for the EDDT Self-Report Form?

The normative sample of 614 children and adolescents was well matched to U.S. Census statistics. In addition, data were collected from 162 children with an ED diagnosis.

Internal consistency and test-retest reliability was high for the scales and clusters. Interrater reliability was good for the total score.

Convergent validity was examined with the BASC-2 SRP. Validity samples were collected with four groups of children representing various special education exceptionalities, including specific learning disabilities, ADHD, psychosis, and social maladjustment.

How do the EDDT's scales/clusters correspond with the federal ED criteria?

What is the Multirater Summary Report?

The Multirater Summary Report, available for free after at least two score reports have been generated for one individual, can be used to review results from multiple raters to create a well-rounded picture of an individual's functioning. It includes a combined score profile to represent similarities and differences between raters graphically and highlights statistically significant score differences. The EDDT Criteria Table aligns each rater’s scores to the federal criteria for ED diagnosis. A sample report is available in the Resources section.

Does the EDDT map to the criteria set forth by the Individuals with Disabilities Education Act (IDEA)?

Yes, the EDDT will help you assess all the areas needed to determine if the student meets the federal eligibility for ED.

How does the EDDT help me assess psychosis/schizophrenia?

The EDDT helps the clinician work through the federal criteria for eligibility for ED in an organized manner. The Possible Psychosis cluster of items screens for common possible psychotic/schizophrenic features but is NOT diagnostic of psychosis or schizophrenia. The clinician may choose to include a recommendation to consider additional evaluation.
