LECTURE 1
INTRODUCTION TO ASSESSMENT TECHNIQUES USED WITH CHILDREN
Prepared By: SHAZIA IQBAL HASHIMI
Questions for considerationQuestions for consideration What is assessment What kinds of assessors conduct psychological
and psycho-educational evaluations? What kinds of classification systems do evaluators
use in making diagnoses and determinations? What tests and measures are most frequently
administered? What questions should advocates consider when
reviewing evaluations? What remedies are available if test results and/or
conclusions appear inaccurate or misleading?

Psychological AssessmentPsychological Assessment Main types of assessment
1. Norm-referenced tests2. Interviews3. Observations4. Informal assessment procedures5. Non-norm referenced tests
Consideration for comprehensive assessment system
The child is an individual and a group member.
The stakeholders- child , parents, teachers, administrators, policy board members, and legislators – as participants in the process as well as consumers of the products.
The program philosophy and the curriculum or intervention strategy of the program
The purpose of evaluating, measuring, or documenting progress
Available methods and accuracy, usability, and meaning of the results.

ASSESSMENT DOMAIN Assessment involves the
specification and verification of problems for the purpose of making different kinds of decisions.
9
Academic Problems. In academic settings, teachers usually make that decision on the basis of their observations of the pupils performance in core content areas; reading, mathematics, written language and communication.
10
Behavior Problems. Behavior problems include failure to get along with peers, delinquent activities, and excessive withdrawn, as well as disruptive and non-compliant behavior.
11
Physical problems. Physical problems include sensory disabilities such as vision or hearing, problems of physical structure for example spina-bifida or cerebral palsy and chronic health problems such as diabetes and asthma.
12
Norm-Referenced TestsNorm-Referenced TestsTests that are standardized on a clearly defined group
◦Normative versus clinical reference groupsGoal: quantify the child’s functioningScores represent a rank within the comparison groupExamples
◦Intelligence◦Academic skills◦Neurocognitive skills◦Motor skills◦Behavioral and emotional functioning
Norm-Referenced TestsNorm-Referenced TestsPsychometric properties
◦Demographically representative standardization sample
◦Reliability Internal consistency, test-retest stability
◦Validity Correlation with other tests measuring same construct Ecological
Psychological tests are imperfect◦Examiner, the child, and the
environment can affect responses and scores
Most attempt to be normally distributedStandard deviation: Commonly used measure of the
extent to which scores deviate from the mean In a Normal distribution, 68% of cases fall between 1
SD above the mean and 1 SD below the meanThe threshold for meeting “clinical significance”
varies across tests, typically > 1 to 2 SDs above or below mean
““Normal” or “Bell” curveNormal” or “Bell” curve
Norm-Referenced TestsNorm-Referenced TestsPercentile ranks
◦Determines child’s position relative to the comparison group
◦Example: What does it mean when a child is in the 35th %tile on an Intelligence test??
Age-Equivalent and Grade-Equivalent scores◦Frequently used on academic
achievement tests◦Sometimes questionable validity
Tests are samples of behavior.
Tests do not reveal directly traits and capacities.
Tests should have adequate
reliability and validity
17
Test scores and other test performances may be adversely affected by temporary states of fatigue, anxiety, stress.
Tests results should be
interpreted in light of the child’s cultural background, primary language and any handicapping conditions.
18
Test results are dependent on child’s cooperation and motivation.
Tests purporting to measure the
same ability may produce different scores for that ability.
19
Test results should be interpreted in relation to other behavioral data and to case history information, never in isolated.
Tests and other assessment
procedures are powerful tools, but their effectiveness will depend on skill and knowledge.

TYPES OF TESTS Informal versus standardized testsIndividual versus group testsMastery versus survey testsSupply versus selection testsSpeed versus power testsObjective versus subjective tests
21
InterviewingInterviewingTypes of interviews:
◦Unstructured—allow child/parent to “tell their story”
◦Semi-structured—provide flexible guidelines, a starting point
◦Structured—most often used to make diagnoses or in research studies, standardized May interfere with rapport Does not provide info on family interactions or a
functional analysis of behavior◦Which types of interview require the
most clinical skill??
Explaining ConfidentialityExplaining ConfidentialityParents sign releases of informationReview concept of confidentiality and its limits
early in clinical interactionLimits to confidentiality:
◦Specific threat to someone else (homicidal ideation)
◦Self-harm is threatened (suicidal plan/intent)◦Sexual and physical abuse (history or current)◦Insurance requests◦Courts◦Generally referral source
Interviewing TechniquesInterviewing TechniquesEstablishing rapport is crucialMoving from open-ended to closed-ended questions (general to specific)
◦Tell me about why you’re here today?◦What about school is most difficult for you?◦Are you failing math because you didn’t hand in your homework….not studying……didn’t understand the material?
Avoid◦Double-barreled questions (“and”, “or”)◦Long, multiple questions◦Leading questions◦Psychological jargon
Example Developmental Example Developmental InterviewInterview
A. History of presenting problemB. Prenatal, perinatal, and early postnatal
historyC. Medical historyD. Acquisition of age-related milestonesE. School historyF. Personality, social, emotional, behavioral
historyG. Family historyH. Expectations about assessment visit
Example Developmental Example Developmental InterviewInterview
A. History of presenting problem◦ Parental description of problem◦ Child’s view of problem◦ Onset◦ Duration◦ Interventions attempted◦ Prior assessments◦ Parents sense of effects of problem,
and sense of child’s understanding
Example Developmental Example Developmental InterviewInterview
B. Prenatal, perinatal, and early postnatal history
◦ Pregnancy◦ Labor and delivery ◦ Birth weight◦ Apgar scores◦ Complications post-birth
Example Developmental Example Developmental InterviewInterview
C. Medical history◦ Across all ages◦ Accidents & injures ◦ Major illnesses◦ Ear infections◦ Neurological conditions◦ Congenital and genetic conditions◦ Hearing and eyesight
Example Developmental Example Developmental InterviewInterview
D. Acquisition of age-related milestones◦ Motor◦ Language◦ Toileting
E. School history◦ Preschool experiences to present – Settings◦ Achievement, grades, strengths and
weaknesses◦ Behavioral, emotional, social functioning◦ IEPs, 504 Plans, accommodations,
modifications◦ What teachers think
Example Developmental Example Developmental InterviewInterview
F. Personality, social, emotional/mood, behavioral history across development◦ Temperament as an infant and toddler◦ 2.5-5 years: Development of play,
aggression, interests◦ 5-11 years: Hobbies, activities, friendships,
family relationships◦ 11 to adolescence: Development of interest
in opposite sex, dating and sex, activities, drug and alcohol use, family relationships, self-concept, goals and aspirations
Example Developmental Example Developmental InterviewInterview
G. Family history◦ Parental history: marriage(s), # children◦ Demographics, ages, education,
occupation, SES◦ Siblings: ages, problems, school history◦ Medical, genetic, developmental,
psychological, abuse problemsH. Expectations about assessment visit
Developmental Developmental ConsiderationsConsiderations
Young children tend to think in concrete ways, while teens may reflects more on feelings and motivations
While age is an obvious indicator of developmental level, language and cognitive levels may also vary with age
Interview format should be adjusted to the individual child’s level◦Open vs. Closed questions
Developmental Developmental ConsiderationsConsiderations
6 year olds might be asked about the difference between preschool and kindergarten
Young teens might be asked about the transition to individualized school schedules and homework, and peer pressures.
Older teens might be asked about college, vocational plans, or separating from parents
Format of the InterviewFormat of the InterviewWho will be interviewed is often a
question with young patients◦e.g., Children under 6 typically are
generally interviewed with parents, then sometimes parents are seen alone
◦e.g., Older children and adolescents are often seen as a family first and then later may be interviewed alone
◦Sex abuse may be an exception
Format of the InterviewFormat of the InterviewIf the clinicians sees family
together it allows for:◦Observation of interactional patterns◦Areas of agreement and
disagreementTell family how their time will be
structured◦Allow them to know if they can save
sensitive topics for when they are alone
Closing the InterviewClosing the InterviewSummarize what has been learned
◦Make sure you understand what the interviewee has reported
◦Helps determine what additional information might be needed
Ask the child/family if they have questions
“Is there anything else I didn’t ask about that you think it would be important for me to know?”
Behavioral ObservationsBehavioral ObservationsPsychological assessments always
include observations about the patient’s behavior during the assessment
Collected throughout the assessment Areas assessed/observed:
◦Orientation (person, place, time)◦General appearance and behavior
Gait, posture, dress, personal hygiene, activity level◦Speech and thought
Coherence, speed, open vs. guarded
Behavioral ObservationsBehavioral ObservationsGeneral response styleMood and affect
◦Euthymic vs. dysthymic◦Labile, blunted, etc.
Reactions to being evaluatedResponse to encouragementAttitude towards selfUnusual habits, mannerisms,
vocalizations
Behavioral ObservationsBehavioral ObservationsHow child relates to parent?How child relates to examiner?How child reacts to test materials
or toys?Is the child age appropriate in
behavior?How is the child’s concentration?
Behavioral ObservationsBehavioral ObservationsAre tantrums seen?Does the child cooperate?What is the extent of child’s
responses?◦short vs. elaborate
How is the child’s speech and language development?
Informal AssessmentInformal AssessmentSelf-monitoring recordsReport cardsPersonal documents
◦Diaries, poems, storiesRole playing
Consideration assessing young children
• Clearly specifying what is to be assessed has priority in the assessment process.
• An assessment procedure should be selected because of its relevance to the characteristics or performance to be measured
42
• Comprehensive assessment requires a variety of procedures.
• Proper use of assessment procedures requires an awareness of their limitations.
• Assessment is a mean to an end and not end in itself.
43
Multimodal AssessmentMultimodal AssessmentObtaining information from several
sources◦Integrate information from several sources◦Recognize limitations of any one source
Using several assessment methodsAssessing several areas of functioning
◦Strengths and weaknessesChild, parents, teachers, previous
evals, school recordsIntelligence, memory, academics,
mood, behavior
Interpreting ResultsInterpreting ResultsAre test results congruent with other
information obtained?How can you account for
discrepancies in teacher, parent, child reports?
Do findings appear to be reliable and valid?
INTEGRATING results from multiple sources is a critical clinical skill
Assessment is a process
1.Evaluating and selecting assessment battery
2.Establishing rapport3.Scoring the assessment battery 4.Interpreting assessment results 5.Formulating recommendations6.Communicating the assessment
