Interview Theory Overview
Interview Theory & Application is the single highest-weighted domain on the entire CFE exam, comprising 15-20% of the Investigation section. This makes it one of the most critical topics to master for exam success.
The Investigation section is consistently rated the most difficult by CFE candidates. Interview techniques form the foundation of fraud examination—your ability to obtain accurate information and admissions can make or break a case. The exam heavily tests your knowledge of proper interviewing methods, question types, and legal considerations.
Interview vs. Interrogation
Understanding the distinction between interviews and interrogations is essential:
| Interview | Interrogation |
|---|---|
| Non-accusatory | Accusatory |
| Information gathering | Confession seeking |
| Open-ended questions | Direct confrontation |
| Used with witnesses, victims, neutral parties | Used with suspects after evidence indicates guilt |
| Cooperative atmosphere | Confrontational atmosphere |
Fraud examiners primarily conduct interviews, not interrogations. The ACFE emphasizes non-coercive, information-gathering techniques rather than aggressive accusatory methods that can lead to false confessions.
The PEACE Model
The PEACE model is a structured, non-confrontational interviewing framework developed in the UK in the early 1990s. It's designed to gather accurate information while minimizing the risk of false confessions. The CFE exam frequently tests knowledge of this model.
Preparation & Planning
Review all case materials, understand the facts, prepare questions, identify interview objectives, select appropriate location, and anticipate possible responses. Never enter an interview unprepared.
Engage & Explain
Build rapport with the interviewee, establish a cooperative atmosphere, explain the purpose of the interview, and outline how it will proceed. This is where you establish baseline behavior to compare against later responses.
Account
The core of the interview—obtain the interviewee's account of events. Use the cognitive approach (free recall, then probing) or conversation management (divide story into sections, probe each segment). Don't interrupt. Let them talk.
Closure
Summarize the main points, give the interviewee opportunity to correct errors or add information, explain next steps, and maintain rapport. Ask if they have anything else to add. Leave the door open for future contact.
Evaluation
Assess whether objectives were achieved, review new information against existing evidence, reflect on what went well and what could improve, and determine next steps in the investigation.
The PEACE model is non-coercive and focused on gathering information, while the Reid Technique uses more accusatory tactics to elicit confessions. Research shows PEACE produces fewer false confessions (0% in studies vs. up to 50% with accusatory methods) while achieving similar rates of true confessions. The CFE exam favors PEACE-style approaches.
Cognitive Interview Technique
The Cognitive Interview (developed by Fisher and Geiselman in 1992) is designed to enhance memory recall through psychological techniques. It's particularly effective with cooperative witnesses and victims.
The 5 Types of Interview Questions
The CFE exam extensively tests your knowledge of the five question types used during fraud interviews. Understanding when and how to use each type is critical.
*Only if reasonable cause exists to believe the respondent committed the fraud
Question Formats
| Format | Description | When to Use |
|---|---|---|
| Open | Allow lengthy responses; begin with who, what, when, where, why, how | Early in interview; information gathering |
| Closed | Elicit yes/no or short factual answers | Confirming specific facts |
| Leading | Suggest the expected answer; imply interviewer already knows | Confirming facts already known; use sparingly |
Leading questions are used to confirm facts already known, not to gather new information. The exam often tests whether candidates understand that leading questions should be used sparingly and only when appropriate.
Kinesic Interview Techniques
Kinesics is the study of body language and nonverbal communication. The kinesic interview technique evaluates how a person's words and actions align to detect possible deception. It's based on the concept that stress causes observable changes in behavior.
Key Principles
- Establish baseline behavior — Observe "normal" behavior during non-threatening questions before asking sensitive ones
- Look for deviations — Changes from baseline when sensitive topics arise may indicate stress or deception
- Evaluate clusters — No single behavior proves deception; look for multiple indicators together
- Consider context — Some people are naturally nervous; cultural differences matter
No single kinesic behavior proves deception. People may exhibit stress indicators for many reasons unrelated to guilt. Kinesics should supplement—not replace—traditional interview techniques. Research shows humans are only slightly better than chance at detecting deception through behavior alone.
Verbal & Nonverbal Deception Indicators
While no indicator definitively proves deception, the following behaviors may warrant further investigation when observed:
| Category | Potential Deception Indicators |
|---|---|
| Eyes | Breaks in eye contact, closing eyes, covering eyes, looking down or away when answering sensitive questions (most important nonverbal sign per ACFE) |
| Face | Excessive blinking, eyebrow movement showing concern/disbelief, dry mouth, lip licking, forced smiles |
| Hands/Arms | Touching face/head repeatedly, crossed arms (defensive posture), fidgeting, grooming gestures, hiding hands |
| Body | Shifting in seat, leaning away, creating physical barriers, change in breathing pattern |
| Verbal | Overly assertive denials, qualified statements ("to the best of my knowledge"), repeating questions to stall, changing story details, selective memory |
| Voice | Change in pitch or pace, voice cracks, excessive pauses, verbal fillers ("um," "uh"), clearing throat |
Three Categories of Meaningful Behavior (Link & Foster)
- Self-initiated verbal statements — Statements the interviewee makes without prompting
- Prompted verbal responses — Responses to structured questions asked by the interviewer
- Nonverbal body positioning — Physiological changes, gestures, and posture
Admission-Seeking Interviews
Admission-seeking questions are only appropriate when there is reasonable cause to believe the respondent is responsible for the fraud. The goals are to:
- Distinguish innocent individuals from culpable ones
- Obtain a valid, voluntary confession
- Obtain a signed written statement acknowledging the facts
- Clear innocent persons (they won't confess unless coerced)
Make a direct statement (not a question) indicating the evidence shows the subject committed the act. Present factually, without anger.
Provide moral justification or face-saving reasons for the behavior. Allow the subject to maintain dignity.
Interrupt weak denials gently; if denials are strong and persistent, reconsider whether subject is guilty.
Respond to excuses or objections by acknowledging them and returning to theme development.
Present two choices, both implying guilt but one more face-saving. "Did you take the money because you were greedy, or because you needed to help your family?"
Have the subject document their admission in writing. Review and have them sign.
Admissions must be voluntary. Never use threats, promises of leniency, coercion, or physical force. An involuntary confession may be inadmissible and can expose the examiner to liability. If a subject requests an attorney, stop the interview immediately.
Legal Considerations
Key Legal Rules for Interviews
- Miranda rights apply only to law enforcement conducting custodial interrogations—private fraud examiners are generally not bound by Miranda, but should still ensure statements are voluntary
- Never promise confidentiality you cannot guarantee
- Question one person at a time (except in rare circumstances)
- Don't make threats or promises of favorable treatment
- Allow bathroom breaks and don't physically detain subjects
- Stop immediately if subject requests an attorney
- Be aware of state-specific recording laws (one-party vs. two-party consent)
CFE Exam Tips
- PEACE model stages: Preparation & Planning → Engage & Explain → Account → Closure → Evaluation
- 5 question types: Introductory → Informational → Assessment → Closing → Admission-Seeking
- Cognitive Interview techniques: Mental reinstatement, report everything, vary chronology, change perspectives
- Tips are #1 detection method — good interviewing encourages tips
- Establish baseline behavior first before asking sensitive questions
- No single behavior proves deception — look for clusters of indicators
- Leading questions confirm facts already known; use sparingly
- Admission-seeking only with reasonable cause to believe guilt
- Admissions must be voluntary — no threats, coercion, or promises
- Open questions for information gathering; closed for confirming facts
- Alternative question presents two guilt-implying choices for face-saving admission
- Eyes are the most important nonverbal indicator (per ACFE)
Practice Questions
Assessment questions are used to evaluate the respondent's credibility and determine whether admission-seeking questions should be asked. They are often hypothetical or "norming" questions designed to elicit reactions that help assess truthfulness.
The "Engage and Explain" stage is where the interviewer builds rapport, establishes baseline behavior, explains the interview purpose, and outlines how it will proceed. This sets the foundation for a cooperative interview.
Leading questions contain a suggested answer and imply the interviewer already knows the information. They are most appropriate for confirming facts already known, not for gathering new information. They should be used sparingly.
According to the ACFE, the eyes are the single most important nonverbal sign. Breaks in eye contact—closing eyes, covering eyes, looking down or away—during sensitive questions can suggest deception. However, no single behavior proves deception.
Admission-seeking interviews have multiple objectives: to obtain a valid voluntary confession, to distinguish innocent from culpable individuals (innocent people don't confess unless coerced), and to obtain a signed written statement acknowledging the facts.
"Changing perspectives" encourages the interviewee to describe events from another person's viewpoint, which can reveal otherwise overlooked details. This is one of the four core cognitive interview techniques developed by Fisher and Geiselman.
Conclusion
Interview techniques represent the highest-weighted domain in the CFE Investigation section. Master the PEACE model stages, understand when to use each of the five question types, and remember that no single behavior proves deception—look for clusters of indicators and always ensure admissions are voluntary.
The key is preparation: know your facts before walking in, establish baseline behavior early, use open questions to gather information, and only move to admission-seeking if reasonable cause exists.
