Previous studies in western countries interviewing styles and confessions

Previous studies in Western countries: Interviewing styles and confessions

  • Humanitarian techniques are more likely to lead to confession rather than dominant techniques.

    • Holmberg & Christianson (2002)

      • 83prisoners(murderers and sexual offenders)in Sweden

      • Self-reported questionnaires

    • Kebbell, Alison & Hurren (2008)

      • 43 prisoners (sexual offenders)in Australia

      • Experiments using fictional cases


Interviewing styles and offenders psychological well being

Interviewing styles and offenders’ psychological well-being

  • Holmberg, Christianson & Wexler (2007)

    • ‘Sense of Coherence’ scales were used to examine the offenders’ psychological well-being.

  • Interviewing styles and confessions are related to the offenders’ psychological well-being.

    • Offenders who felt respected during the interview showed higher SOC than those who did not feel respected.

    • Offenders who had admitted their crimes showed higher SOC than deniers.


The purpose of the current study

The purpose of the current study

  • This presentation has two aims:

    • To describe the interviewing techniques used in Japan

    • To investigate the relationship between the following variables;

      • Interviewing styles and confessions

      • The interrogators’ and suspects’ feelings after the interrogation


The characteristics of the japanese legal system

The characteristics of the Japanese legal system

  • A maximum of 23 days from arrest to the institution of prosecution

  • Corroborating evidence is required.

  • Recording police interviews (suspects, victim and witnesses) are not allowed.

    • Recording the parts of interviews by prosecutors has been introduced.

    • Those who were not mentally retarded or mentally ill.

    • Gender: Male 271, female 5

    • Age: M=40.5 (SD=8.7),median38.5

    • Years of investigative experience:

      M=11.2(SD=8.2)

    • Rank: Constables 27, Sergeants 132,

Methods analysis

Methods: Analysis

    • Factor analysis(MLmethod, promaxrotation) for interviewing techniques

    • Anon-hierarchical cluster analysis (K-means)for classifying the interviewing styles

  • Interviewing styles and feelings

    • 2 × 4 ANOVAs (full or partial confession ×four types of interview styles) were conducted to examine the relationships between the interviewing styles and feelings of police officers / suspects

the five factors.


Result interviewing style

Result: Interviewing style

  • Evidence focused approach

    • The highest score on Presentation of Evidence factor

    • The second highest scores on Active Listening and Confrontation factors

      • Listen to the suspects’ account closely, show evidence and sometimes confront the suspect with the evidence?

  • Confrontational approach

    • The highest score on Confrontation factor

    • The second highest score on the Discussion of the crime factor

      • Confront the suspects not about inconsistencies between evidence and suspects’ accounts but by discussing their criminal offences and victims?


Result interviewing style1

Result: Interviewingstyle

  • Relationship focused approach

    • The highest scores on Active Listening, Rapport Building, and Discussion of the crime factors

      • Listen to the suspects’ stories very attentively, attempt to build a good relationship, and discuss the crime and victims to make the suspects think about them

  • Undifferentiated approach

    • The lowest scores on the five factors

      • Less likelyto employ specific interviewing techniques


Result information

Result: Information

  • One item: The suspect was willing to provide information unknown to the police

    • Main effects for confession type (F (1, 256) = 19.01, p < .001) and interviewing style F (3, 256) = 3.17, p = .003).


Result sympathy

Result:Sympathy

  • Three items: I experienced the same feelings as the suspect did./ I felt affection for the suspect. / I felt sorry for the suspect.

    • Main effect for use of interviewing style, F (3, 259) = 3.19,

      p = .02.


Result suspects satisfaction

Result: Suspects’ satisfaction

  • Four items: The suspect appeared to experience a sense of relief./The suspect appeared to be pleased that he/she had confessed

    • Main effects for confession type (F (1, 256) = 39.04, p < .001) and interviewing style F (3, 256) = 5.06, p = .002).


Result suspects remorse

Result: Suspects’ remorse

  • Oneitem: The suspect appeared to regret having committed a crime.

    • Main effects for confession type (F (1, 256) = 20.98, p < .001) and interviewing style F (3, 256) = 4.36, p = .005).


Conclusion

Conclusion

  • Four types of interviewing styles were identified.

  • Police officers who employed the relationship focused approach were more likely

    • to sympathize with the suspects

    • to believe that the suspects disclosed information

    • to believe that the suspects were satisfied with their confessions and remorseful about their crimes


Limitations

Limitations

  • All ratings were provided by the police officers.

    • These are the police officers’ perspectives.

  • Studies examining the offenders’ opinions are needed.

    • I will survey prisoners about their feelings after being interrogated.
