The Children's Depression Inventory 2 (CDI 2) is a comprehensive multi-rater assessment of depressive symptoms in youth aged 7 to 17 years. Depressive symptomatology is quantified by the CDI 2 based on reports from children/adolescents, teachers and parents. Developed based on the Original CDI, the CDI 2 retains many of the essential features of its predecessor and introduces a number of important refinements. The updated version includes new items that focus on the core aspects of childhood depression, revised scales that are more reliable and valid, as well as new norms that are representative of the U.S. population. Also updated and enhanced are the normative samples of the Parent and Teacher forms. Together, the inventories are a family of tools that accurately assess the presence and the severity of depressive symptoms.

How to Use the Assessment

The CDI 2 is available in paper-and-pencil, and software formats.

Paper-and-Pencil Administration and Scoring

All CDI 2 forms can be administered and scored using the MHS QuikScore format. The rater writes on the external layers of the form, and the results transfer through to a hidden scoring grid within the internal layers. The assessor then uses the internal layers for tabulating results. Each QuikScore form includes conversion tables, which are used to convert raw scores to T-scores. For individuals who wish to use software or online scoring, CDI 2 items are also available as Response/E-Paper forms that do not include the scoring pages.

Software Scoring

The CDI 2 can be scored using the scoring software by entering responses from a completed paper-and-pencil administration into the software program.


• Emotional Problems
• Functional Problems


• Negative Mood
• Negative Self-Esteem
• Ineffectiveness
• Interpersonal Problems


CDI 2: Self-Report (CDI 2:SR)

The full-length CDI 2 Self-Report Form is ideal when assessors require a more robust description of the child's depressive symptoms. The CDI 2:SR is 28-item assessment that yields a Total Score, two scale scores (Emotional Problems and Functional Problems), and four subscale scores.

CDI 2: Self-Report (Short) version (CDI 2:SR[S])

The CDI 2:SR(S) Form is an efficient screening measure that contains 12 items and takes about half the time of the full-length version to administer (5-10 minutes).The CDI 2:SR(S) has excellent psychometric properties and yields a Total Score that is generally very comparable to the one produced by the full-length version.

CDI: Teacher (CDI:T) and CDI: Parent (CDI:P)

The CDI:T and CDI:P Forms consist of items that correspond to the self-report version and are suitably rephrased. Item selection for the parent and teacher forms was guided to maximize validity, and thus focused on observable manifestations of depression

Technical Information

Technical Information

The CDI 2:SR normative sample (note that this is the same normative sample for the CDI:SR Short; CDI:SR[S]) includes 1,100 children aged 7 to 17 years from 26 different states in the U.S. The sample is evenly proportioned in terms of age and gender, with 50 males and 50 females at each age. The racial/ethnic distribution of the sample matches the U.S. census distribution very closely (i.e., all races were within 1% of Census targets, (based on the 2000 U.S. Census report). Overall, the normative sample includes a reasonable spread of geographical locations of all four major regions of the U.S.

A clinical sample of 319 youth aged 7-17 years (M age = 12.63 years, SD age = 3.02 years) diagnosed with Major Depressive Disorder (MDD; 33.86%), Attention-Deficit/Hyperactive Disorder (ADHD; 28.21%), Conduct Disorder (CD; 14.11%), Generalized Anxiety Disorder (GAD; 13.79%), or Oppositional Defiant Disorder (ODD; 10.03%) was obtained.


There are three report types available through the software: the Assessment Report (provides detailed results from one administration), the Progress Report (provides an overview of change over time by combining results from up to four administrations), and the Comparative Report (provides an overview of the child's symptoms from a multi-rater perspective and highlights inter-rater differences in scores from up to five different raters).
