Study Notes

Reliability and Validity

Reliability refers to the consistency of a measurement
Standard error of measurement quantifies the amount of error in a score
Confidence interval represents the range of scores likely to contain a true score
Validity describes the extent to which a test measures what it intends to measure
Content validity assesses if test items represent the domain being evaluated
Criterion validity examines the relationship between the test score and an outcome
Concurrent validity relates a test score to current outcomes
Predictive validity relates a test score to future performance
Construct validity is the overarching type of validity, measuring whether the test measures the intended construct
Convergent validity refers to correlation with other measures of the same construct
Discriminant validity refers to lack of correlation with measures of different constructs

Reliability Coefficients

Not all forms of reliability should be expected to be high
Interrater reliability, the agreement between raters, can be low to moderate

IQ Theories

Dominant IQ theories differ in their focus.

Cognitive Assessments

Traditional cognitive assessments align with Cattell-Horn-Carroll (CHC) theory
Examples of such assessments include WISC-V, Stanford-Binet, Woodcock-Johnson, and KABC.

Achievement Tests

Newer achievement tests are often co-normed with IQ tests to match IDEA 2004 requirements
Achievement Discrepancy Analysis is used in these tests

CBE, CBA, and CBM

Curriculum-Based Evaluation (CBE) helps educators address learning and behavior problems by aligning assessments with curriculum standards
Based on CBE, curriculum-based assessments (CBA) assess student strengths,
Curriculum-based measurement (CBM) is a standardized measure of general outcome aligned with curriculum standards

Social/Emotional/Behavioral Assessment Methods

Behavior rating scales are a commonly used method to assess social-emotional, behavioral, and mental health functioning.
Projective measures (drawing, thematic techniques, sentence completion) have been debated for their usefulness.
Interviews (clinical, structured, semi-structured) gather information on social-emotional functioning.
Observations assess behavior in its context.
Direct behavior rating (DBR) combines elements of both rating scales and direct observations.
Self-report measures (rating scales, personality measures) allow students to report their own perspectives.
Functional Behavior Assessments (FBAs) identify environmental conditions that maintain problematic behaviors
Universal Screening is increasingly used in schools to identify students who may need more support.

Non-Discriminatory Assessment

Ortiz's model emphasizes understanding cultural and linguistic backgrounds when evaluating students.
Exposure to different cultures and languages affects student performance.
True peers have similar experiences and opportunities when being tested

Student Behaviors and Interventions

Factors like student motivation or difficulty are important considerations in teaching
Effective teachers structure classrooms to promote participation and discourage disruptive behavior
Teachers should consider prior knowledge and skills when designing learning activities
Contingency management, self-regulation, and self-management are important interventions to positively impact student engagement, motivation, self-regulation, and problem solving
Evidence-based interventions (EBIs) are manualized and scripted, explicit, using step-by-step instructions for consistency and reproduction.

Systems Theory

Systems theory views aspects of a system (e.g., individuals, groups) as interdependent, and the interplay among them.

Trends in School Psychology

Changing social conditions, evolving legal aspects of education, increased diversity in students, and an increased focus on implementation science (how to translate research findings to practical application) are important factors impacting the profession of school psychology.
