The Children’s Depression Inventory 2nd Edition (CDI 2) is a comprehensive multi-rater assessment of depressive symptoms in children and adolescents from ages 7 to 17, which offers the flexibility of application in either clinical or educational settings. When results from the CDI 2 are combined with other sources of verified information, the CDI 2 can aid in early identification of depressive symptoms, diagnosis of Depression and related disorders, and monitoring of treatment effectiveness.
Key Areas Measured:
- Emotional Problems
- Functional Problems
- Negative Mood
- Negative Self-Esteem
- 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.
The CDI 2 Self-Report (full-length and short) normative sample includes 1,100 children and adolescents aged 7 to 17 from 26 different states in the U.S. The sample is evenly proportioned in terms of age and gender, with 50 male and 50 female children and adolescents at each age. The racial/ethnic distribution of the sample closely matches the U.S. census distribution (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 to 17 (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.
