Interviews with asylum seekers are an important part of investigating the applicant's need of international protection. Few studies have examined if the questions used in interviews allow detailed and accurate narratives. In the current study, we analysed question style, question type, and question order from interviews of 80 official asylum cases realised by Finnish state authorities in 2017–2018. In accordance with best practise, questions were predominantly asked in an information-gathering style. However, four-fifths of the questions were closed questions, and one-tenth were open questions. The recommended question order was followed to a small degree. Possibilities on how to improve the quantity and the accuracy of the information elicited from the interviews are discussed. Future research should assess which type of questions that are most efficient in eliciting relevant information within the asylum context as well as investigating the accuracy of the interpretation.

Previous studies of homicides in South Africa have examined serial murders and mass killings. While some scholars have examined parricides in African countries such as Ghana and Zimbabwe, few have examined the intersection of parricide and multiple victim homicides in the context of South Africa. This paper examines multiple victim parricides in a South African context using newspapers and court records as data. Eighteen cases of multiple-victim parricides were identified and analysed. Our findings indicate that multiple victim parricides in South Africa are shaped by residential patterns as well as social and cultural factors that are unique to South Africa that are embodied in the offence characteristics. The implications on the findings are discussed.

There is general absence of research about the relationship between trauma symptoms and immediate and delayed suggestibility in children who have been sexually abused. The participants were 134 children aged between 7 and 17 years with a history of reported sexual abuse. All children completed the Gudjonsson Suggestibility Scale (2), a non-verbal IQ test, and The University of California at Los Angeles Child/Adolescent Reaction Index for post-traumatic stress (UCLA-PTSD-RI-5). Delayed suggestibility was measured after a 1 week delay. A Hierarchical Regression showed that trauma symptoms accounted overall for 43.4% of the variance in delayed suggestibility after controlling for age, sex, IQ, and immediate recall (a large effect size). There was a small shared variance between trauma and immediate suggestibility (low effect size). The findings strongly suggest that the severity of trauma symptoms impact more on delayed than immediate suggestibility. The theoretical and forensic implications are discussed.

The efficacy of principles of persuasion and influence in aiding uncooperative individuals to become more cooperative has been well documented in the basic science literature. Less known is their effects in investigative interviews. This study examined the effects of liking (positivity) on informational elements produced in investigative interviews. Interviewees participated in a mock theft experiment and were randomly assigned to tell the truth or lie about the potential theft. Half the interviews were conducted in a high liking condition, the other half in a low liking condition. High liking produced less relevant details in both the interviews and written statements for truthtellers. Rapport had direct, positive effects on relevant and irrelevant details in the interviews but not the written statements and mediated the association between liking and relevant and irrelevant details in the interviews. Veracity condition moderated the association between liking and informational elements; liking had negative effects on relevant details for truthtellers in the interviews and written statements but positive effects on irrelevant details for liars in written statements. These findings suggested the need to examine how and when liking as a social influence tactic may be effective in investigative interviews.

The aim of this study consisted in analysing the cases of drug-facilitated sexual assault— chemical submission—from 2008 to 2017. A total of 240 cases registered during this period within the territorial area of the Spanish Civil Guard were analysed. Results show an increasing incidence of sexual assault cases that are drug-facilitated in order to annul the will of the victim, or at least that there is a greater awareness to report these cases. From the analyses carried out, distinctive characteristics of this type of sexual offences were observed with respect to other modalities, in the sense that they are linked to leisure situations (at night, on weekends and holiday periods) although the place of commission is fundamentally the victim's or the perpetrator's residence. The profile of the victim is that of a young woman, of legal age (with a mean age of 25 years) and Spanish, although foreign women are also vulnerable victims. When the victim is male, the mean age decreases notably (20 years) with a higher incidence among minors. The aggressor is eminently male, older (around 30 years) and also Spanish. Databases can be a good starting point to frame the phenomenon, elucidating some of the main variables that intervene in these crimes, such as the moment and place of commission, as well as those persons most inclined to suffer them and, in the opposite pole, those most likely to carry out this type of criminal act.

Research has indicated that life-course persistent offenders typically vary their offending style, following a criminal career progression from co- to solo-offending. Few studies have investigated the offenders who contemporaneously mix their style of offending. A sample of 1,047 male adolescent offenders from the Pathways to Desistance study was investigated over a 7-year period. Participants were identified as solo, co or contemporaneous mixed style (CMS) offenders for each wave of data and one-way between groups analysis of variance was conducted to examine variations between the different offending styles in terms of offending frequencies, exposure to violence, peer antisocial behaviour and influence, resistance to peer influence, impulse control and psychopathy. CMS offenders were found to consistently report significantly higher rates of offending and present significantly higher negative risk factors and lower protective risk factors than solo- and co-offenders for the duration of the study. A multinomial logistic regression was used to investigate predictors of offending style with CMS as the reference category. Higher levels of exposure to violence and peer antisocial behaviour and lower levels of impulse control predicted membership of the CMS group for the first part of the study when compared with co-offenders; and higher levels of exposure to violence and peer antisocial behaviour continued to predict CMS offending when compared to solo-offenders until the end of the study.

The literature on information elicitation in psycholegal settings has predominantly focused on the investigator–interviewee dynamic, with little attention to the environment in which the interview takes place. The present study compared the impact of two interview locations on the disclosure of crime-related information and perceptions of rapport building. Participants experienced a virtual reality mock crime, and 1 week later were interviewed at either their homes, or a formal room akin to a real-world police interview room. Participants in the home setting reported feeling more at ease and in control compared to participants interviewed in the formal room. However, we found no differences between conditions on the quantity and quality of information disclosure and participants' perceptions of rapport building. Based on our findings, we found no advantages or disadvantages for conducting witness interviews at their homes. However, these results underscore the practicality of interviewing witnesses outside the police interview room if deemed as more convenient.

Prisoners' affective education is a hot topic in criminal psychology. The lack of the social support for prisoners means that they are more prone to loneliness. The mental health status of the prisoners directly concerns their social adaptation when released. We therefore explored the relationship between loneliness, psychological affect, and control source in 201 prisoners. Prisoners completed the state and trait loneliness scale, the affectal scale, the internal control, powerful others, and chance scale. Mediation effect analysis was conducted to explore the mediation role of the control source from influence of loneliness on psychological affect. State loneliness indirectly affected positive affect through internal control factors. Trait loneliness directly affected negative affect, and trait loneliness indirectly affected negative affect through opportunity factors. Overall, this study uncovers some of the psychological mechanisms underlying emotional state in prisoners, highlights the need for effective psychological correction programmes in the prison system and provides reference for effectual ascension of prisoners out of jail.

To what extent stereotypical deceptive behaviours such as gaze aversion and fidgeting actually influence people's credibility judgements remain largely unknown. In this study, we directly manipulated the presence/absence of such behaviours to investigate this. Participants were shown four truthful videos in which we manipulated the presence of stereotypical cues and asked them to judge how credible the person in each video is. Moreover, research consistently shows that decision making is influenced by various cognitive biases. One example is the primacy effect, which implies that people form an opinion early in the decision process. Information acquired early will have the largest influence on how subsequent information will be interpreted. To investigate a possible primacy effect, we also manipulated whether these cues were present towards the beginning or the end of the video (i.e. the timing of the manipulation). In line with our expectations, the presence of stereotypical cues significantly lowered the observed credibility, showing that the presence of these cues indeed influences credibility judgements. The timing of the cues had no effect.
