In the article Interviewing behaviors in police investigators: a field study of a current US sample, what research question did the study hope to answer? | Researchers wanted to determine if the recommended interviewing techniques were currently being used in real-world police interviewers and how effective the NIJ guidelines process was to influence Post -NIJ police interviews. |
The NIJ put together a group of eyewitness researchers, police investigators, prosecutors and defense attorneys | Technical Working Group on Eyewitness Evidence to improve investigative interviewing |
National Guidelines on Eyewitness Identification (1999) | was distributed to all police dept. in the United States Training manual distributed later in (2003) to meet training needs |
Published in 1992 PEACE interviewing model including a updated more refined five-tier national interviewing strategy | the first national interviewing training program in the UK |
Previous Research Interviewing behavior in a US sample of Child Protection Service, Schreiber et al. (2006) | Found that investigators used closed-ended questions, suggestive information into the interview repeated questions, introduced co-witness information and encourage witness to provide hypothetical information |
what is the difference between this study and the previous study? | this was the first US study that examined real-world adult witness investigative interviewing behavior AFTER the distribution of the National Guidelines on Eyewitness Identification |
Previous study: results of UK PEACE investigative interviewing course including 75 police witness interviews | The witness interviews resembled a statement-taking exercise instead of an interview. Did not use techniques that enhanced witness recall. Interviewers performance was poor regardless of having training or not. However when given more time/supervision interview improved |
Cognitive Interview | The first empirically based adult witness interview protocol. The NIJ has used these recommendations in its own guidelines, when applied can help elicit more information from witnesses |
Methodology | 26 investigators from two South Florida police dept. investigators were contacted by phone. Benefit-CI training,in exchange for copies of audiotapes of witness/victim interviews. A scoring system was used on the transcribed audiotaped interviews. |
Methodology | Scorers underwent training for several months. Coders were blind to the study's objective. Scoring systems criteria 1. Question type 2. presence of positive interviewing techniques 3. presence of negative interviewing techniques |
Results of the study | The findings were in line with UK , Canadian and earlier studies in the US (smaller samples) Investigators did not follow recommended interviewing principles, most info was elicited by closed-end questions over half of questions were yes/No. Positive techniques were long pauses, rapport building |
Limitations | The sample was not random participants were recruited from only one southeastern county in the USA. Only used voluntary police dept. and investigators. Investigators selected and submitted their own interviewing tapes all these factors may contribute to biases |
conclusion | The data from this research suggest that NIJ-guidelines process was not effective in improving investigative interviewing in this sample. Although the NIJ-guidelines were mailed to all police dept. in the USA there was a failure to adopt the new method of interviewing and seemed to be deemed unimportant |
