Investigative interviewing and memory: How accurate are interviewers recollections of investigative interviews?

Contrary to interviewing guidelines, a considerable portion of witness interviews are not recorded. Investigators’ memory, their interview notes, and any subsequent interview reports therefore become important pieces of evidence; the accuracy of interviewers’ memory or such reports is therefore of crucial importance when interviewers testify in court regarding witness interviews. A detailed recollection of the actual exchange during such interviews and how information was elicited from the witness will allow for a better assessment of statement veracity in court. ^ Two studies were designed to examine interviewers’ memory for a prior witness interview. Study One varied interviewer note-taking and type of subsequent interview report written by interviewers by including a sample of undergraduates and implementing a two-week delay between interview and recall. Study Two varied levels of interviewing experience in addition to report type and note-taking by comparing experienced police interviewers to a student sample. Participants interviewed a mock witness about a crime, while taking notes or not, and wrote an interview report two weeks later (Study One) or immediately after (Study Two). Interview reports were written either in a summarized format, which asked interviewers for a summary of everything that occurred during the interview, or verbatim format, which asked interviewers to record in transcript format the questions they asked and the witness’s responses. Interviews were videotaped and transcribed. Transcriptions were compared to interview reports to score for accuracy and omission of interview content. ^ Results from both studies indicate that much interview information is lost between interview and report especially after a two-week delay. The majority of information reported by interviewers is accurate, although even interviewers who recalled information immediately after still reported a troubling amount of inaccurate information. Note-taking was found to increase accuracy and completeness of interviewer reports especially after a two week delay. Report type only influenced recall of interviewer questions. Experienced police interviewers were not any better at recalling a prior witness interview than student interviewers. Results emphasize the need to record witness interviews to allow for more accurate and complete interview reconstruction by interviewers, even if interview notes are available. ^

The effect of note taking on memory for details in investigative interviews

Across 3 experiments, the effect of different styles of note taking, summary and access to notes was examined for memory for the details contained in a witness interview. In Experiment 1, participants (N = 40) were asked to either take notes or listen as they watched a witness interview. In Experiment 2, participants (N = 84) were asked to either take notes in one of three ways (i.e., conventional, linear, spidergraph) or listen as they watched a witness interview. In Experiment 3, participants (N = 112) were asked to take notes using the conventional or spidergraph method of note taking while they watched a witness interview and were subsequently given an opportunity to review their notes or sit quietly. Participants were then either granted access to their notes during testing or were not provided with their notes. Results of the first two experiments revealed that note takers outperformed listeners. Experiment 2 showed that conventional note takers outperformed those who used organizational styles of note taking, and post-hoc analyses revealed that recall performance was associated with note quality. Experiment 3 showed that participants who had access to their notes performed the best. The implications of these findings for police training programs in investigative interviewing are discussed.

How (not) to interview children : interviews with young children in sexual abuse investigations in Finland

The present thesis had two main objectives: The first was to assess how child sexual abuse (CSA) interviews in Finland are conducted through analysing the interviewing techniques applied and the language used by the interviewers, as well as to suggest ways to improve interviews if they were found to have deficiencies. The second main aim was to contribute to the growing research corpus concerning CSA interviews, in particular, by addressing how interviewers follow up information provided by the child, by analysing whether child health care professionals would use childadapted language, and by studying the kind of modifications in the verbal behaviour of interviewers and children that were associated with a) repeated interviews, b) a support person’s presence at the interview, and c) the use of anatomically detailed dolls. Two complementary samples of CSA interviews were analysed. The first one was composed of child interviews with 3-12-year-old children (N = 27) that had been considered problematic by lawyers or other involved professionals (Studies I and IV). The second sample consisted of unselected interviews (N = 43) with children aged 3 to 8 years conducted in a number of hospitals in different parts of the country (Studies II and III). Study I: The verbal interaction between interviewer and child was analysed in a sample of interviews that had been considered to be problematic by involved professionals. Results showed that interviewers used inappropriate questioning techniques, relying on option-posing, specific suggestive and unspecific suggestive questions to a significant extent, these comprising around 50% of all interviewer utterances. The proportion of invitations, which the research community recommends interviewers to rely on, was strikingly low. Invitations and directive utterances were associated with an increase in informative responses by the child in terms of response type, number of new details reported, as well as length of response. The opposite was true for option-posing and suggestive utterances. Longer questions by the interviewer (in number of words) often rendered no reply from the child, whereas shorter questions were followed by descriptive answers. Even after the child had provided an informative answer, interviewers failed to follow up the information in an adequate way and instead continued to rely on focused and leading questions. Study II: Due to the possible bias of the sample analysed in Study I, the most important analyses were rerun with the unselected sample and reported separately. Results were quite similar between the two studies, indicating that the problems observed in Study I, with interviewers relying on option-posing and suggestive questions to a significant extent, are likely to be general and not specific for those interviews. Even if suggestive questions were slightly less and invitations slightly more common in this sample than in the previous study, almost half of the interviewer questions were still optionposing or suggestive, and also in this sample, interviewers failed to follow up information by the child in a facilitating manner. Differentiating between judicial and contextual details showed that while facilitators, invitations, and directive utterances elicited more contextual than judicial details, the opposite was true for specific suggestive utterances. These results might be explained by the reluctance of children to describe sexual details related to the abuse events. Alternatively, they may also be due to children describing incorrect sexual details as a result of suggestive interviewing techniques. Study III: This study examined features of the language used by the interviewers. Interviewer utterances included multiple questions, long statements, complicated grammar and concepts, as well as unclear references to persons and situations. More than a fifth of the interviewer utterances were coded as belonging to at least one of these categories. The results suggest that even professionals who are experienced in interacting with children may have difficulties in using a child-sensitive language, adding to the pool of studies showing similar problems to occur in legal hearings with children conducted by lawyers. As children rarely comment on, or even recognise, their lack of comprehension, the use of a language that is too complex can have detrimental consequences for the outcomes of investigative interviews. Interviewers used different approaches to introduce the topic of abuse. While 15% of the children spontaneously addressed the topic of abuse, probably indicating that they felt confident with the interviewer and the situation, in almost 50% of the cases, the interviewer introduced the topic of abuse in a way that can be considered leading. Interviews were characterised by a lack of structure, apparent in frequent rapid switches of topic by the interviewer. This manner was associated with a decrease in the number of new details provided by the children. Study IV: This study analysed possible changes in the interview dynamics associated with repeated interviewing, the presence of a support person (related to the child), and the use of anatomically detailed (AD) dolls. Repeated interviewing, in combination with suggestive questions, has previously been found to seriously contaminate children’s accounts. In the present material, interviewers used significantly more suggestive utterances in the repeated condition, thus endangering the reliability of the children’s reports. Few studies have investigated the effects of a support person’s presence at the interview. The results of the present study showed that interviewers talked more and children provided less information when a support person was present. Supporting some earlier findings regarding the use of AD dolls, the present results showed that using AD dolls was associated with longer interviewer utterances and shorter, less responsive, and less detailed child responses. Interviewers used up to five times more unspecific suggestive utterances when dolls were used, for instance through repeatedly asking the child to show “what really happened” with the dolls. Conclusion: The results indicate that CSA interviews in Finland are not conducted in a manner that follows best practice as defined by the research community and as stated in a number of guidelines. When comparing these questioning strategies with the recommendations, which have been predominant in the field for more than ten years now, it can be concluded that the interviews analysed were conducted in a manner that undermines the possibility to elicit an uncontaminated and accurate narrative from the children. A particularly worrying finding was the fact that interviewers did not follow up relevant information by the children in an adequate way. A number of clinical implications can be drawn from the results, particularly concerning the need for improvement in the quality of CSA interviews. There is convincing research regarding how to improve CSA interviews, notably through training forensic child interviewers to use a structured interviewing protocol, and providing them with continuous supervision and feedback. Allocating appropriate resources to improve the quality of forensic child interviews is a matter of protecting the rights of all persons involved in CSA investigations, in particular those of the children.

The question of question types in police interviews:a review of the literature from a psychological and linguistic perspective

The past two decades has seen a plethora of papers and academic research conducted on investigative interviews with victims, witnesses and suspected offenders, with a particular focus on questioning techniques and typologies. However, despite this research, there still remain significant discrepancies amongst academic researchers and practitioners over how best to describe types of questions. This article considers the available literature relating to interviews with children and adults from both a psychological and linguistic perspective. In particular, we examine how different types of questions are described, and explore the discrepancies between competing definitions. © 2010, equinox publishing.

Attachement, tempérament et déclaration de l’enfant victime d’agression sexuelle durant l’audition

Cette thèse a pour objectif principal d’explorer les contributions de l’attachement et du tempérament sur la quantité d’informations dévoilées par les enfants victimes d’agression sexuelle. Les auditions de 25 enfants âgés de trois à sept ans ont été codifiées sur le plan du type de questions et du nombre de détails. Le tempérament de l’enfant a été évalué par un questionnaire rempli par le parent. Les représentations d’attachement et les habiletés verbales ont été évaluées par l’entremise de tâches auprès de sous-échantillons d’enfants. Pour répondre à la question de recherche principale, le questionnaire de tempérament TABC-r a d’abord été traduit en français puis validé auprès de 231 parents issus de la population générale, ce qui a constitué un objectif secondaire de la thèse. Les résultats indiquent que le TABC-r version canadienne-française présente des propriétés psychométriques adéquates et similaires à la version originale. La structure factorielle, la cohérence interne, la fidélité inter-juge, la stabilité temporelle et la validité divergente sont très satisfaisantes. La validité convergente est soutenue par des relations attendues avec les problèmes de comportements et les relations familiales, mis à part des liens non retrouvés avec les habiletés cognitives. Ces résultats, les limites de l’étude et les pistes de recherche futures sont discutés. Les résultats obtenus concernant l’audition indiquent que les enfants victimes d’agression sexuelle présentant un attachement plus sécurisé et moins évitant rapportent davantage de détails en moyenne aux questions proposant un choix. Les associations modérées, quoique non significatives, entre le manque de persistance à la tâche et la quantité moyenne de détails aux questions proposant un choix, et entre l’attachement sécurisé et évitant et la quantité moyenne d’informations rapportées globalement sont décrites compte tenu de la petite taille de l’échantillon. Lorsqu’ils sont considérés simultanément, la sécurité d’attachement et le manque de persistance à la tâche contribuent potentiellement de façon complémentaire à expliquer une part de variance du nombre moyen de détails aux questions de reconnaissance lorsque l’âge est contrôlé, mais seul l’apport de la sécurité d’attachement est significatif. Ces résultats, les limites de l’étude, les pistes de recherches futures et les implications pour la conduite d’auditions sont discutés.

Entrevues auprès d’enfants qui dévoilent une agression sexuelle : examen du processus d’enquête et du parcours judiciaire des dossiers

Cette étude a été rendue possible grâce aux bourses doctorales accordées à la première auteure par les organismes suivants : le Conseil de recherche en sciences humaines (CRSH), la Chaire interuniversitaire Marie-Vincent sur les agressions sexuelles envers les enfants (CIMV), l’Équipe violence sexuelle et santé (ÉVISSA) et le Centre de recherche interdisciplinaire sur les problèmes conjugaux et les agressions sexuelles (CRIPCAS). Cette étude a également été soutenue par une subvention de recherche accordée par le Bureau d’aide aux victimes d’actes criminelle (BAVAC) du ministère de la justice du Québec accordée à Mireille Cyr.

Évaluation du rôle des caractéristiques personnelles des enquêteurs policiers sur la conduite d'entrevues d’enquête auprès d’enfants victimes d’agression sexuelle

Depuis les années 1990, de nombreuses recherches ont porté sur le dévoilement de l’agression sexuelle chez l’enfant et sur les caractéristiques y étant associées. Outre les facteurs liés à l’enfant et au contexte, le type de questions utilisé par l’intervieweur (notamment les invitations et les questions ouvertes) est une variable déterminante pour le dévoilement de l’enfant et la quantité de détails qui sera fournie entourant l’agression sexuelle. Bien que plusieurs enquêteurs reçoivent une formation sur l’utilisation des questions ouvertes dans les entrevues avec les enfants, peu d’entre eux utilisent un style de question approprié une fois sur le terrain. L’objectif de cette recherche vise à déterminer si certaines caractéristiques personnelles des enquêteurs sont associées à leur adhésion à un protocole d’entrevue structuré pour lequel ils ont été formés, à l’utilisation de questions ouvertes dans des entrevues d’enquête auprès d’enfants soupçonnés d’avoir vécu une agression sexuelle et à la quantité de détails dévoilés par l’enfant lors de ces entrevues. Deux études ont été menées pour répondre à cette question. La première étude a été effectuée à l'École nationale de police du Québec auprès de 24 enquêteurs de police ayant suivi une formation d'une semaine visant l’apprentissage du protocole d’entrevue structuré du National Institute of Child Health and Human Development (NICHD). Le genre féminin, les habiletés cognitives et le trait de personnalité Ouverture à l’expérience sont trois caractéristiques personnelles qui ont été reliées positivement à la performance des enquêteurs lors d’une entrevue simulée avec un comédien jouant le rôle d’un enfant victime d’agression sexuelle, tandis que le nombre d’années d’expérience et la capacité de gestion du stress de ces enquêteurs ont montré une relation négative avec cette performance. Dans la seconde étude effectuée sur le terrain auprès de 13 enquêteurs du Service de police de la Ville de Montréal, 114 entrevues conduites auprès d’enfants ayant dévoilé une agression sexuelle ont été recueillies et cotées pour mesurer l’adhésion au protocole d’entrevue du NICHD, le ratio de questions ouvertes et la quantité de détails dévoilés par l’enfant par question posée par l’enquêteur. L’intelligence émotionnelle et les traits de personnalité Extraversion, Esprit consciencieux et Agréabilité ont été trouvés comme des caractéristiques personnelles positivement associées à l’adhésion au protocole d’entrevue et à l’utilisation de questions ouvertes, tandis que le nombre d’années d’expérience et le trait de personnalité Névrosisme ont été négativement associés à ces deux critères de performance. Le niveau d’habiletés cognitives des enquêteurs a quant à lui montré une association positive avec la quantité de détails dévoilés par l’enfant. La signification et l’interprétation de ces résultats, de même que les implications potentielles pour la sélection et la formation des enquêteurs sont finalement discutées.

Remembering remotely:would video-mediation impair witnesses' memory reports?

Witnesses often experience lengthy delays prior to being interviewed, during which their memories inevitably decay. Video-communication technology - favored by intergovernmental organizations for playing larger roles in judicial processes - might circumvent some of the resourcing problems that can exacerbate such delays. However, whereas video-mediation might facilitate expeditious interviewing, it might also harm rapport-building, make witnesses uncomfortable, and thereby undermine the quality and detail of their reports. Participants viewed a crime film and were interviewed either one day later via video-link, one day later face-to-face, or 1-2 weeks later face-to-face. Video-mediation neither influenced the detail or the accuracy of participants' reports, nor their ratings of the quality of the interviews. However, participants who underwent video-mediated interviews after a short delay gave more accurate, detailed reports than participants who waited longer to be interviewed face-to-face. This study provides initial empirical evidence that video-mediated communication (VMC) could facilitate the expeditious conduct of high-quality investigative interviews. © 2013 © 2013 Taylor & Francis.

Recall, verbatim memory and remembered narratives

Memory is central to investigative interviews with witnesses and suspects, yet decades of research have shown that remembering is subject to constructive and reconstructive processes that can adversely impact the reliability of accounts that are elicited at interview. In this chapter we first outline research concerning our memory for events (‘episodic memory’) before moving on to discuss the ways in which our attempts to validate and communicate those memories can bias what is eventually reported. We then focus on some of the implications this can have for investigative interviews, specifically the problem of ‘skill fade’ in interviewing, the impact of implicit beliefs about memory and issues surrounding the reliability of recollections of direct speech. We conclude that appropriately structuring the retrieval context is the key to achieving best memory evidence.

Narrative interviews: an important resource in qualitative research

Objetives This methodological study explain and emphasize the extent and fertility of the narrative interview in qualitative research. Methods To describe the narrative method within the qualitative research. Results The qualitative research method is characterized by addressing issues related to the singularities of the field and individuals investigated, being the narrative interviews a powerful method for use by researchers who aggregate it. They allow the deepening of research, the combination of life stories with socio-historical contexts, making the understanding of the senses that produce changes in the beliefs and values that motivate and justify the actions of possible informants. Conclusion The use of narrative is an advantageous investigative resource in qualitative research, in which the narrative is a traditional form of communication whose purpose is to serve content from which the subjective experiences can be transmitted.

Police Interviews with Victims and Suspects of Violent and Sexual Crimes : Interviewee's experiences and interview outcomes

The police interview is one of the most important investigative tools that law enforcement has close at hand, and police interview methods have changed during the twentieth century. A good police interview is conducted in the frame of the law, is governed by the interview goal, and is influenced by facilitating factors that may affect the elicited report. The present doctoral dissertation focuses on police interviews in cases of very serious crimes of violence and sexual offences. Results reveal crime victims’ and perpetrators’ experiences of being interviewed and police officers’ attitudes towards conducting interviews related to traumatizing crimes. Study 1 revealed that when police officers interviewed murderers and sexual offenders, the interviewees perceived attitudes characterized by either dominance or humanity. Police interviews marked by dominance and suspects’ responses of anxiety were mainly associated with a higher proportion of denials, whereas an approach marked by humanity, and responses of being respected were significantly associated with admissions. In line with Study 1, the victims of rape and aggravated assault in Study 2 also revealed the experience of two police interview styles, where an interviewing style marked by dominance and responses of anxiety was significantly associated with crime victims’ omissions of information. Moreover, a humanitarian interviewing style, and crime victims’ feelings of being respected and co-operative, was significantly related to crime victims providing all information from painful events. Special squad police officers’ attitudes towards interviewing crime victims, in Study 3, also showed a humanitarian approach and two dominant approaches, one affective and the other refusing. The attitude towards interviewing suspects of crimes in focus revealed humanitarian and dominant interviewing attitudes, and an approach marked by kindness. The present thesis shows that, during their entire career, an overwhelming majority of the special squad police officers have experienced stressful events during patrol as well as investigative duty. Results show that symptoms from stressful event exposures and coping mechanisms are associated with negative attitudes towards interviewing suspects and supportive attitudes towards crime victim interviews. Thus, experiences from stressful exposures may automatically activate ego-defensive functions that automatically generate dominant attitudes. Moreover, it is important to offer police officers who have been exposed to stressful events the opportunity to work through their experiences, for example, through debriefing procedures. After debriefings, police officers are better prepared to meet crime victims and suspects and, through conscious closed-loop processes, to conduct police interviews without awaking ego-defensive functions.

Addressing the project implementation challenges in the Saudi Arabian power supply industry: an investigative approach towards improving project delivery

For many decades, the Kingdom of Saudi Arabia has been widely known for being a reliable oil exporter. This fact, however, has not exempted it from facing significant domestic energy challenges. One of the most pressing of these challenges involves bridging the widening electricity supply-demand gap where, currently, the demand is growing at a very fast rate. One crucial means to address this challenge is through delivering power supply projects with maximum efficiency. Project delivery delay, however, is not uncommon in this highly capital-intensive industry, indicating electricity supplies are not coping with the demand increases. To provide a deeper insight into the challenges of project implementation and efficient practice, this research adopts a pragmatic approach by triangulating literature, questionnaires and semi-structured interviews. The research was conducted in the Saudi Arabian power supply industry – Western Operating Area. A total of 105 usable questionnaires were collected, and 28 recorded, semi-structured interviews were conducted, analysed and synthesised to produce a conceptual model of what constitutes the project implementation challenges in the investigated industry. This was achieved by conducting a comprehensive ranking analysis applied to all 58 identified and surveyed factors which, according to project practitioners in the investigated industry, contribute to project delay. 28 of these project delay factors were selected as the "most important" ones. Factor Analysis was employed to structure these 28 most important project delay factors into the following meaningful set of 7 project implementation challenges: Saudi Electricity Company's contractual commitments, Saudi Electricity Company's communication and coordination effectiveness, contractors' project planning and project control effectiveness, consultant-related aspects, manpower challenges and material uncertainties, Saudi Electricity Company's tendering system, and lack of project requirements clarity. The study has implications for industry policy in that it provides a coherent assessment of the key project stakeholders' central problems. From this analysis, pragmatic recommendations are proposed that, if enacted, will minimise the significance of the identified problems on future project outcomes, thus helping to ensure the electricity supply-demand gap is diminished.
