“…Two domains were not included in the analyses. First, as the coding was performed with transcriptions, it was not possible to code for context manipulation techniques (see also Hagsand, Zajac, et al ., 2022). Second, collaboration techniques were observed in less than 1% of sequences, thus offering little statistical power for analysis (see also Hagsand, Zajac, et al ., 2022; Izotovas et al ., 2021; and Kelly et al ., 2015, for similar findings).…”

“…As the taxonomy framework (Kelly et al., 2013) had been primarily tested in American samples (except for one Swedish study; Hagsand, Zajac, et al., 2022, and one UK study; Izotovas et al., 2021), it was instructive to examine the relative rates of domain use 6 across the whole interrogation and their relationships to one another in the current European sample. Therefore, six paired t‐tests comparing use of each domain to use of each of the other domains were performed, using a Bonferroni correction, yielding a critical p‐value = 0.008, to examine the use of different domains, as analyzed on the sequence level.…”

“…The more objective measurement of domain emphasis in the present study was derived from an equation 4 (see also, Hagsand, Zajac, et al. , 2022). Consider a simple example for the actual scoring (see also Table 3) of one interrogation in the sample.…”

“…Similar to Hagsand, Zajac, et al (2022), direct questions and statements were much more frequent than strategic techniques. While around 70% of sequences in the present study concerned direct questions/statements, the rate reported by Hagsand, Zajac, et al (2022) was even higher at 91.8% (Study 1) and 87.8% (Study 2). We hypothesized that when the crimes are relatively low-stakes, investigators do not need to rely on the domains to secure suspect cooperation, but when the level of resistance from suspects is heightened, such as in high-stakes crimes, investigators may find more complex strategies beneficial.…”

“…If the summed within‐domain technique score for a given time block exceeded M combined , a two (2) was coded. If no techniques were scored within a domain in a given time block, a zero (0) was coded” (Hagsand, Zajac, et al., 2022, p. 8).…”

This archival study was the first in Sweden, and the first outside of the US and the UK, to apply the (Kelly et al., Psychology, Public Policy, and Law, 9, 165–178, 2013) taxonomy of interrogation methods framework to repeated police interrogations of adult suspects in high‐stakes crimes. Audio/video recordings (N = 19) were collected from the Swedish Police Authority of repeated interrogations of three suspects in three criminal cases. The interaction between interrogators and suspects were scored according to the taxonomy framework (Kelly et al., Psychology, Public Policy, and Law, 9, 165–178, 2013; Kelly et al., Law and Human Behavior, 40, 295–309, 2016). First, there was an association between the use of different domains. Rapport and relationship building was moderately and negatively associated with confrontation/competition and presentation of evidence. Moreover, confrontation/competition was moderately and positively related to emotion provocation and presentation of evidence. Second, changes were observed during the interrogations. Presentation of evidence was lower in the beginning than in the middle block. Suspect cooperation was higher in the beginning than both the middle and end blocks. Third, an ordered logistic regression showed that rapport and relationship building were associated with increased suspect cooperation, and confrontation/competition and presentation of evidence were associated with decreased cooperation. The study's results are mostly in line with other taxonomy studies on high‐stakes crimes from the US and the UK. The findings are discussed in light of theoretical frameworks, empirical findings, and current police practice. We also highlight the need for further research.
