Depression
Approximately 2.5 percent of children and 8 percent of adolescents in the U.S. have depression. An NIMH-sponsored study of 9 to 17-year-olds, more than 6 percent in a 6-month period were depressed and 4.9 percent having major depression.
Research indicates that depression onset is occurring earlier in life today than in past.

ContentIdentification
1. A review of the literature pertaining to child, adolescent, and adult development and depression
2. A review of item content from existing instruments
3. An examination of current diagnostic criteria based on the DSM-IV
4. Consideration of item content to reflect depressed mood among individuals across a wide age range
5. Suggestions from colleagues
6. Wrote 175 items across 16 content domains based on literature and DSM diagnostic criteria
Identification of relevant content was accomplished through:
Features
• Uses a Four-point Item response format • Strongly Agree• Agree• Disagree• Strongly Disagree
• Comes with CAD-SP that scores, profiles, reports data, and facilitates interpretation• Standard scores (T-scores)• Percentile ranks• Confidence intervals• Qualitative classifications• Graphical profile display
Features
• Single form appropriate for ages 8 to 79 years
• Easily administered 50 item scale
• Ten minute completion time
• Multidimensional view of depressions - Four Symptom Scales - Twelve Major Depressive Symptoms - Six Clinical Clusters - Three Veracity Scales
• Easily hand scored or optional software scoring system
• Based on DSM-IV diagnostic criteria and clinical literature
Features
• Critical Item clusters identify risk factors for potential self-harm
• Exceptional psychometric qualities
• Large, diverse, national normative sample
• Content appropriate, children, and adolescents without sacrificing face validity

Scale Variance and Demographics
Four Clinical Scales
1. Depressed Mood (DM)• 23 items - - feelings of extreme unhappiness,
sadness, loneliness, lack of personal significance, poor self-concept, and discouraged outlook on life.
2. Anxiety/Worry (AW)• 11 items - - increased anxiety, worry, fear, and related
symptoms
Four Clinical Scales
3. Diminished Interest (DI)• 6 items - - loss of interest in activities that previously
were enjoyable, diminished excitement, lack of enjoyment, and not wanting to participate in daily routines
4. Cognitive and Physical Fatigue (CPF)• 10 items - - somatic issues, fatigue, sleeplessness,
insufficient energy, lack of mental of physical clarity, clumsiness or slowness, and inability to complete tasks
Six Critical Item Clusters
1. Hopelessness• 5 items - - sense that current conditions are
permanent and with no promise for improvement, extreme unhappiness, having given up on the future, and inability to continue the current level of suffering
2. Self-Devaluation• 5 items - - sense of self-loathing, failure, extreme
loneliness, and loss of personal meaning
3. Sleep/Fatigue• 3 items - - feelings of fatigue, lack of energy, and
desire to do little other than sleep
Six Critical Item Clusters
4. Failure• 3 items - - sense of limited personal competence or
an overwhelming sense of failure
5. Worry• 3 items - - feelings of generalized worry and worry
that bad things may happen
6. Nervous• 3 items - - feelings of anxiety, nervousness, and
limited ability to relax

Test Materials
• Test Kit Includes:• Comprehensive Professional Manual
• CAD Rating Form
• CAD Profile Form/Score Form
• CAD Scoring Program Software and Users’ Manual
AppropriatePopulations
• Normed, standardized, and validated foruse with children through adults:• ages 8 to 79 years
• both genders
• all racial/ethnic backgrounds
• all geographical regions and residential communities
• all socio-economic strata
• all disability subgroups
• all linguistic or cultural backgrounds
ProfessionalRequirements
• Individuals with adequate training may administer and score the CAD with supervision
• CAD interpretation requires formal training and/or graduate degree in:
• clinical psychology
• school psychology
• counseling psychology
• developmental/behavioral pediatrics
• or a related behavioral field
Scoring
• The CAD can be hand-scored or scored using the computerized CAD-SP
• Hand-scoring is accomplished using a carbonless form• Skipped Items and missing responses
• CAD-SP prorates scores when at least 90% of items on a scale are completed
• If more than 10% of the items on a scale are omitted,
CAD-SP treats scale as invalid
Score Report
Obtaining the Score Report• Administer CAD Rating Form• Open CAD Scoring Program (CAD-SP) on computer• Enter basic demographic data• Enter item responses
CAD-SP automatically calculates and provides• T-Scores• Percentile ranks• Confidence intervals• Clinical classifications• Graphical display of results

Clinical Interpretation
Quantitative and Qualitative Interpretation Process
5-Step Interpretation Process
1. Interpret CAD Total Scale (CAD TS)
2. Interpret CAD Symptom Scales, Validity Scales and Critical Item Clusters
3. Interpret CAD Individual Items
4. Interpreting the follow-up Clinical Interview
5. Compare performance on the CAD in light of other test and background information
CAD Total Score(CAD TS)
• The CAD TS is best measure of “General Affectivity”• T Score Metric (i.e., Mean = 50, SD = 10)• Percentile Ranks• Confidence Intervals• Qualitative Classifications
≤ 59 = Normal Range60-69 = Mild Clinical Risk70-79 = Significant Clinical Risk≥ 80 = Very Significant Clinical Risk
