  • Authors: Craig Dowden, Craig Bennell, and Sarah Bloomfield

Abstract

  • Offender profiling is widely popular and a focus of academic study.

  • Concerns regarding scientific inquiry development in offender profiling have arisen.

  • The study reviews the type and quality of studies on offender profiling over the last 31 years (1976-2007).

  • Key findings:

    • Limited publication of multiple articles by researchers; papers are spread across many journals, hindering knowledge synthesis.

    • Most publications are discussion pieces explaining profiling basics rather than empirical inquiries.

    • A noteworthy increase in peer-reviewed articles, yet many lack statistical sophistication.

  • Future research suggestions and recommendations for streamlining efforts in this field are proposed.

Key Terms

  • Offender profiling: A technique for identifying major personality and behavioral traits based on crime analysis (Douglas et al. 1986).

  • Knowledge synthesis: The process of collecting and summarizing past research to enhance understanding.

  • Knowledge transfer: The method of sharing knowledge among different individuals or groups.

Historical Context

  • Profiling gained attention with early cases like the Jack the Ripper murders and is used as an investigative tool to prioritize suspects in serial crimes (Woodworth & Porter 1999).

  • In 1986, the FBI's Behavioral Science Unit received 600 profiling requests annually, increasing to over 1200 by 1996 (Witkin 1996).

  • Despite the popularity, many literature reviews indicate that profiling's perception is influenced more by media portrayal than empirical evidence (Davies 1994, McCann 1992).

  • Kocsis (1999) noted a significant gap between profiler reputation and actual capabilities.

Research Methodology

Content Analysis Overview

  • This study conducts a content analysis of 132 articles pertaining to offender profiling, examining:

    • Trends over 31 years.

    • Most active journals and researchers.

    • Types of information reported and statistical methods utilized.

    • Peer-review status.

Sample Selection

  • Studies from major databases (Medline, PubMed, PsycINFO, National Criminal Justice Reference System) evaluated using keywords related to profiling and criminal behavior, including terms like:

    • Psychological profiling

    • Criminal profiling

    • Serial crimes (e.g., murder, rape, arson)

  • Exclusions:

    • Books, book chapters, unpublished documents, geographical profiling, and linkage analysis were not included due to distinct methodologies.

Coding Methodology

  • A coding manual was created to categorize studies based on:

    • Year of publication

    • Author affiliation

    • Crime type studied

    • Emphasis of the article (e.g., case study, theoretical study)

    • Statistical scrutiny (no statistics, descriptive statistics, inferential statistics)

    • Peer review status

  • Inter-rater reliability tested through Cohen’s kappa with satisfactory results for most codes (e.g., author affiliation kappa = 0.77, emphasis kappa = 0.80).

Results

Publication Trends

  • The analysis divided publications into five-year intervals from 1976 to 2007:

    • Significant increase in the number of articles on offender profiling.

    • 53 journals published articles with most contributing only one (60.4%).

    • Leading journal: International Journal of Offender Therapy and Comparative Criminology (n=18), followed by FBI Law Enforcement Bulletin (n=9).

Author Contributions

  • Only 18 out of about 160 authors published three or more articles on profiling.

  • Author characteristics indicate a blend of disciplines, primarily psychologists (34.09%) and multidisciplinary teams (28.03%).

Crime Type Focus

  • Articles categorized by crime type:

    • Unspecified crime (41.67%, n=55) dominated, with homicide (19.70%, n=26) and rape (11.36%, n=15) following.

Emphasis and Study Types

  • Predominant study types:

    • Discussion pieces (28.79%, n=38)

    • Basic assumptions studies (27.27%, n=36)

  • Few articles focused on theoretical frameworks (5%).

Statistical Analysis Levels

  • Analysis revealed a lack of statistical analysis in many articles:

    • 56.81% of studies had no statistical basis.

    • A substantial increase in inferential statistics usage post-1995, with 41.41% including this method.

Peer Review Status

  • 75% of articles were peer-reviewed, a marked increase since 1995 (where less than half were peer-reviewed).

Discussion

Research Development and Gaps

  • This preliminary quantitative summary highlights the rapid growth but also the uneven quality of the literature.

  • Limited continuity in research due to fragmented publication across many journals.

  • Literature predominantly consists of discussion pieces lacking rigorous methodology.

Research Needs

  • More empirical validating studies needed, especially regarding profiling processes and foundational theories.

  • Calls for collaboration between academic researchers and practical law enforcement professionals for robust research endeavors.

Methodological Challenges

  • Common issues include access to reliable data and validity concerns in profiling studies.

  • Advocates for comprehensive data collection from multiple reliable sources to enhance research quality.

Conclusions

  • Despite increased profiling usage, the literature is highly fragmented and lacks coherence.

  • Recommendations include fostering theoretical and methodological sophistication through enhanced collaboration and utilizing empirical data for practical application in offender profiling.
