Ethical Research Practices in Psychology: Comprehensive EPPP Study Guide

EPPP Decoded: Why Your Measurement Tools Decide Whether You Can Trust Your Diagnosis

A breakdown of the psychometric concepts the EPPP loves to test, from scales of measurement to item response theory, translated into plain language with clinical examples. We cover reliability, validity, common measurement errors, and the six steps of scale development. Built for exam prep, useful for anyone who wants to think more critically about the tools they use in the room. IAB Content Tags:Education, Standardized Testing, Mental Health, Careers, Science

Statistical Tests in Psychological Research

This study guide is a highly accessible EPPP preparation tool that balances technical psychometric definitions with simplified, real-world analogies designed for intuitive understanding. By breaking down complex parametric and non-parametric statistical tests into their core mechanics, assumptions, and APA reporting standards, it ensures candidates can confidently select and interpret the right analysis. Ultimately, the guide bridges the gap between abstract mathematical formulas and practical psychological research contexts, making it an excellent resource for exam mastery.

Ethical Research Practices in Psychology: Comprehensive EPPP Study Guide

We elaborate on the four core principles from the Belmont Report—autonomy, beneficence, nonmaleficence, and justice—while detailing informed consent processes, protections for vulnerable populations, confidentiality safeguards, Institutional Review Board (IRB) functions, permissible use of deception with debriefing, and alignment with the APA Ethics Code and federal regulations such as 45 CFR

seven original practice questions designed to help with EPPP preparation on Validity Concepts in Psychological Research.

Here are seven original practice questions designed to help with EPPP preparation on Validity Concepts in Psychological Research. Each question includes four options, the correct answer, and a detailed rationale.

Validity Concepts in Psychological Research: Essential EPPP Study Guide

This comprehensive guide examines the four core types of validity—internal, external, construct, and statistical conclusion—that form the foundation for evaluating psychological research and ensuring trustworthy conclusions. It provides precise definitions, detailed explanations of common threats with clinically relevant examples, and practical strategies to strengthen each validity type, making complex psychometric principles accessible for EPPP preparation. The material also includes guidance on applying these concepts when critically evaluating studies, along with two practice questions and rationales that mirror the exam format, enabling candidates to effectively identify and address validity concerns in research design and application.
