Vulnerable suspects in police interviews: exploring current practice in England and Wales

Mentally disordered individuals are increasingly coming into contact with the police. The current study explored investigative interview practice with mentally disordered suspects to examine how they respond, and the impact this has on the level of information obtained. Transcripts of interviews conducted with vulnerable and non-vulnerable suspects (N = 66) were analysed using a specially designed coding framework. Results highlighted that best practice is generally not being adhered to regarding questioning techniques (for example, the use of open questions). Furthermore, while police officers altered their communication to suit the needs of the vulnerable suspect, they were also more likely to use minimisation tactics. Mentally disordered suspects sought more clarification for open questions and provided more information to closed questions. They also demonstrated higher levels of vulnerability (suggestibility and compliance) when compared to their non-vulnerable counterparts. Implications regarding interviewing methods for this vulnerable group are discussed

CYR61/CCN1: A Novel Mediator of Epidermal Hyperplasia and Inflammation in Psoriasis?

The complex pathogenesis of psoriasis is still not fully understood. The study by Sun et al. (2015) suggests that CYR61 (now named CCN1), a secreted matricellular protein, has a role in the pathogenesis of psoriasis, and thus targeting CCN1 represents a potential therapeutic strategy in its treatment

Dissecting the psoriasis transcriptome: inflammatory- and cytokine-driven gene expression in lesions from 163 patients

Abstract Background Psoriasis lesions are characterized by large-scale shifts in gene expression. Mechanisms that underlie differentially expressed genes (DEGs), however, are not completely understood. We analyzed existing datasets to evaluate genome-wide expression in lesions from 163 psoriasis patients. Our aims were to identify mechanisms that drive differential expression and to characterize heterogeneity among lesions in this large sample. Results We identified 1233 psoriasis-increased DEGs and 977 psoriasis-decreased DEGs. Increased DEGs were attributed to keratinocyte activity (56%) and infiltration of lesions by T-cells (14%) and macrophages (11%). Decreased DEGs, in contrast, were associated with adipose tissue (63%), epidermis (14%) and dermis (4%). KC/epidermis DEGs were enriched for genes induced by IL-1, IL-17A and IL-20 family cytokines, and were also disproportionately associated with AP-1 binding sites. Among all patients, 50% exhibited a heightened inflammatory signature, with increased expression of genes expressed by T-cells, monocytes and dendritic cells. 66% of patients displayed an IFN-γ-strong signature, with increased expression of genes induced by IFN-γ in addition to several other cytokines (e.g., IL-1, IL-17A and TNF). We show that such differences in gene expression can be used to differentiate between etanercept responders and non-responders. Conclusions Psoriasis DEGs are partly explained by shifts in the cellular composition of psoriasis lesions. Epidermal DEGs, however, may be driven by the activity of AP-1 and cellular responses to IL-1, IL-17A and IL-20 family cytokines. Among patients, we uncovered a range of inflammatory- and cytokine-associated gene expression patterns. Such patterns may provide biomarkers for predicting individual responses to biologic therapy.http://deepblue.lib.umich.edu/bitstream/2027.42/112670/1/12864_2012_Article_5257.pd

Psoriasis drug development and GWAS interpretation through in silico analysis of transcription factor binding sites

BackgroundPsoriasis is a cytokine‐mediated skin disease that can be treated effectively with immunosuppressive biologic agents. These medications, however, are not equally effective in all patients and are poorly suited for treating mild psoriasis. To develop more targeted therapies, interfering with transcription factor (TF) activity is a promising strategy.MethodsMeta‐analysis was used to identify differentially expressed genes (DEGs) in the lesional skin from psoriasis patients (n = 237). We compiled a dictionary of 2935 binding sites representing empirically‐determined binding affinities of TFs and unconventional DNA‐binding proteins (uDBPs). This dictionary was screened to identify “psoriasis response elements” (PREs) overrepresented in sequences upstream of psoriasis DEGs.ResultsPREs are recognized by IRF1, ISGF3, NF‐kappaB and multiple TFs with helix‐turn‐helix (homeo) or other all‐alpha‐helical (high‐mobility group) DNA‐binding domains. We identified a limited set of DEGs that encode proteins interacting with PRE motifs, including TFs (GATA3, EHF, FOXM1, SOX5) and uDBPs (AVEN, RBM8A, GPAM, WISP2). PREs were prominent within enhancer regions near cytokine‐encoding DEGs (IL17A, IL19 and IL1B), suggesting that PREs might be incorporated into complex decoy oligonucleotides (cdODNs). To illustrate this idea, we designed a cdODN to concomitantly target psoriasis‐activated TFs (i.e., FOXM1, ISGF3, IRF1 and NF‐kappaB). Finally, we screened psoriasis‐associated SNPs to identify risk alleles that disrupt or engender PRE motifs. This identified possible sites of allele‐specific TF/uDBP binding and showed that PREs are disproportionately disrupted by psoriasis risk alleles.ConclusionsWe identified new TF/uDBP candidates and developed an approach that (i) connects transcriptome informatics to cdODN drug development and (ii) enhances our ability to interpret GWAS findings. Disruption of PRE motifs by psoriasis risk alleles may contribute to disease susceptibility.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155494/1/ctm2s4016901500545-sup-0001.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155494/2/ctm2s4016901500545-sup-0018.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155494/3/ctm2s4016901500545-sup-0002.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155494/4/ctm2s4016901500545.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155494/5/ctm2s4016901500545-sup-0009.pd

A systematic review on the relationship between self-esteem and interrogative suggestibility

Some factors, such as age, learning disability and mental health difficulties, have been identified as making police suspects more vulnerable to suggestibility and false confessions during interview. However, there has been no systematic review on the association between self-esteem and suggestibility. Seven electronic bibliographic databases and reference lists of previous literature reviews of suggestibility in children were searched. Selected studies were quality assessed using pre-defined criteria before data were extracted. Electronic searches yielded 1914 hits. Of these, 685 duplicates, 1181 irrelevant references and 39 references that did not meet the inclusion criteria were removed. Nine publications were included in the review. Significant correlations between self-esteem and suggestibility, most notably on the Yield 1 subscale of the GSS, were found but four of the nine studies found no significant correlation. The prevalent use of self-report measures and lack of clarity in defining self-esteem limit the validity of those studies

The Link Between Suggestibility, Compliance, and False Confessions: A Review using Experimental and Field Studies

Expert witnesses and scholarssometimesdisagree on whether suggestibility and compliance are related to people’s tendency to falsely confess. Hence, the principal aim of this review was to amass the available evidence on the link between suggestibility and complianceand false confessions. We reviewed experimental data in which false confessions were experimentally evoked and suggestibilityand compliancewere measured. Furthermore, we reviewed field data ofpotential false confessions and their relationship with suggestibility and compliance. These diverse databases converge to the same conclusion. We unequivocally found that high levels of suggestibility (andto a lesser extentcompliance)were associated with an increased vulnerability to falsely confess. Suggestibility measurements might be informative for expert witnesses who must evaluate the false confession potential in legal cases

Behind the confession: Relating false confession, interrogative compliance, personality traits, and psychopathy

The present study further supports the established notion that personality traits contribute to the phenomenon of false confessions and compliance in an interrogative setting. Furthermore, the study provides an investigation into the more recent interest in the potential effect of psychopathic traits in this context. A sample of university students (N = 607) completed questionnaires measuring psychopathic traits, interrogative compliance, and the big five personality factors. Of these, only 4.9% (n=30) claimed to have falsely confessed to an academic or criminal offense, with no participant taking the blame for both types of offense. Across measures the big five personality traits were the strongest predictors of compliance. The five personality traits accounted for 17.9 % of the total variance in compliance, with neuroticism being the strongest predictor, followed by openness and agreeableness. Psychopathy accounted for 3.3% of variance, with the lifestyle facet being the only significant predictor. After controlling for the big five personality factors, psychopathy only accounted for a small percentage of interrogative compliance, indicating that interrogators should take into account a person’s personality traits during the interrogation.N/

Memory distortions: When suggestions cannot be easily ignored

In the present study, the persistence of personal false memories (FMs) after social feedback that denies their truth was assessed. Participants imitated actions performed by the experimenter (Session 1) and watched a doctored video with performed and critical “fake” actions (Session 2), followed by a memory rating and a recognition task. A few days later (Session 3), participants were clearly told that some memories were false and received daily reminders of the correct list of objects/actions before testing their memory again in Session 4. Results of both memory ratings and recognition indicated effective FM implantation. Interestingly, response times for correct rejections were longer for fake than true objects, suggesting participants struggled to ignore false suggestions. Crucial for our aim, Session 4 showed that FM persisted also after the debriefing and repeated presentations of correct list of objects/actions, suggesting that FMs for actions are rather difficult to discard
