The problem of interviewing drug addicts in custody: A study of interrogative suggestibility and compliance

Abstract

The interrogation of drug addicts in custody presents a problem. The reliability of confessions made either under the influence of drugs or during drug withdrawal may be adversely affected. This study explores the effect of drug use and drug withdrawal on interrogative suggestibility and compliance. These two psychological factors are relevant to erroneous testimony. The interrogative suggestibility and compliance of heroin addicts on an inpatient drug unit were measured on opiates, whilst withdrawing from opiates and drug free. The interrogative suggestibility and compliance of the group of subjects as a whole did not differ significantly in these three conditions. However the results did suggest that a subgroup of vulnerable individuals may have been more suggestible when under the influence of opiates. Further work is needed to clarify these results and to aid professionals assessing fitness for interview and cases of retracted confessions.     

Negative emotional states,life adversity,and interrogative suggestibility

Purpose. Interrogative suggestibility has been shown to vary according to cognitive and personality factors and if reliably measured may predict performance in real forensic interviews. It is therefore of both theoretical and practical interest to identify which psychological factors are most closely related to suggestible responding. This study examines the extent to which individual differences in negative emotional states predict performance on a measure of interrogative suggestibility and also tests the assumption that self‐reports of negative life events are associated with suggestibility. Method. A non‐clinical sample (N= 80) of participants was administered the brief form of the Depression Anxiety Stress Scales (DASS‐21), the Life Experiences Survey (LES), and the Gudjonsson Suggestibility Scale (GSS‐1). Results. Negative emotional states were found to correlate positively, although moderately, with all of the suggestibility measures. Multiple regression analyses found significant predictive models emerged for Yield 1, Yield 2, and Total Suggestibility. Each of these predicted a small proportion of the variance. Negative life event impact ratings were not associated with interrogative suggestibility. Conclusions. The findings suggest that brief self‐report measures of negative emotional states are limited as predictors of interrogative suggestibility. The results also call into question the predictive utility of traditional checklist measures of life adversity for forensic purposes.     

The relationship of suggestibility and compliance with self-deception and other-deception

The aim of the study was to assess the relationship of interrogative suggestibility and compliance with other-deception and self-deception. The Gudjonsson Suggestibility Scale (GSS 1), the Gudjonsson Compliance Scale (GCS), the Eysenck Personality Questionnaire (EPQ), and the Other and Self-Deception questionnaires (ODQ and SDQ) were administered to 237 Icelandic prison inmates. Other and Self-Deception scores did not correlate significantly with suggestibility and compliance, whereas significant correlations were found between the deception scores and EPQ Psychoticism, Neuroticism and Lie scores. The EPQ Lie score explained about one-third of the variance in the ODQ score, suggesting a considerable overlap between the two impression management measures. The most important practical implication of the findings is that self-favouring bias does not appear to significantly influence suggestibility and compliance scores.     

Further data on interrogative suggestibility and compliance scores following instructed malingering

Purpose. This study examined whether people can successfully feign high levels of interrogative suggestibility and compliance as measured by the Gudjonsson Suggestibility Scales (GSS) and the Gudjonsson Compliance Scale (GCS) when given instructions to malinger. Methods. Participants (N = 90) were randomly allocated to one of three groups that received: (1) instructions to give into leading questions in order to look vulnerable to suggestions, (2) instructions to be compliant with the examiner, or (3) the standard GSS/GCS instructions. Results. One of the two malingering instructions led to modestly elevated scores of total suggestibility, while subscales remained unaffected. In contrast, both malingering groups obtained highly elevated compliance scores. Conclusions. These findings suggest that heightened suggestibility is rather difficult to malinger, thereby confirming the reliability of the GSS. On the other hand, it might be easier to malingering compliance as measured with the self‐report GCS.     

Individual differences in interrogative suggestibility: life adversity and field dependence

Since the turn of the century much research has explored the concept of interrogative suggestibility, with recent research highlighting a sizeable link between the reported experience of negative life events (NLEs) and performance on the Gudjonsson Suggestibility Scale 1 (GSS1). The present study sought to reinvestigate the previously found novel relationship, as well as explore the role of field dependence as a possible coping mechanism implemented during interview by such vulnerable interviewees. As expected, highly significant correlations between NLEs and the suggestibility components of the GSS emerged. Field dependence, however, failed to correlate significantly with either NLE or GSS scores. Nonetheless, some additional findings relating to age, NLEs, and shift scores on the GSS were noted, which may help further our understanding of the NLE to interrogative suggestibility relationship. A new group of vulnerable interviewees, who are as yet unrecognized by the police or courts, has also been identified.     

The relationship between intelligence,memory and interrogative suggestibility in young offenders

Abstract

The study investigated the relationship between interrogative suggestibility and relevant cognitive factors as proposed by Gudjonsson and Clark (1986). The subjects were fifty-eight adolescent young offenders resident in a national children's centre with secure facilities. All were administered the Gudjonsson Suggestibility Scale and the Wechsler Intelligence Scale for Children. Interrogative suggestibility correlated negatively with intelligence and recall memory. Limited evidence of range effects was found for the relationship between intelligence and suggestibility, but not for the relationship between recall memory and suggestibility.     

True and false memories in middle childhood: the relationship with cognitive functioning

This study was designed to investigate developmental changes in true and false memories and to detect links among them in middle childhood. Participants were 372 Italian children (from 6 to 11 years, 174 males) divided into two age groups. After hearing a story, children provided a free-recall and their true and false retrieved information was measured. Then children were repeatedly asked some true and misleading questions about the story and their cued-recall and interrogative suggestibility were measured. Finally, children again recalled the story to assess the post-event misinformation effect of the suggested information. Individual differences in fluid intelligence, working memory and executive functions were also assessed to investigate their relationships with true and false memories. Typical age effects were found in memory recall and interrogative suggestibility. Interesting links among true, spontaneous and suggested false memories were found. Finally, analyses did not reveal the existence of a relationship between suggestibility and cognitive functioning.     

The Role of Suggestibility in Personal Injury Claims

Interrogative suggestibility and other psychological vulnerabilities are often assessed in the forensic criminal context in disputed confession cases. Such an assessment may also be relevant in disputing the validity of a confession by a plaintiff in a tort claim. This paper will outline the relevancy of suggestibility in the personal injury context, the reasons why an individual may falsely confess, how interrogative techniques may increase the likelihood of a false confession, false confession and suggestibility research, and methodology to be used in assessing vulnerability to falsely confessing.     

Examining the Role of Interrogative Suggestibility in Miranda Rights Comprehension in Adolescents

This study aimed to further clarify the association between interrogative suggestibility and Miranda rights comprehension in adolescents; in particular, we examined whether intellectual ability (IQ) serves as a mediator of this relationship. Participants completed Grisso’s Miranda Instruments, the Wechsler Abbreviated Scale of Intelligence, and the Gudjonsson Suggestibility Scale. Many youth demonstrated poor comprehension of their rights, particularly younger and less intellectually capable adolescents. Both yield and shift components of interrogative suggestibility were inversely related to rights comprehension; however, IQ fully mediated these relationships. Neither demographic variables (gender, ethnicity, socio-economic status after controlling for IQ, and English as a second language (ESL) status) nor previous police experience were significantly associated with rights comprehension in the present sample. The implications of these findings are discussed.     

Verbal ability,depression, and anxiety as correlates of interrogative suggestibility in children exposed to life adversities

In the present study, we assess the relationship of verbal ability, depression, and anxiety with interrogative suggestibility (IS) in a sample of children exposed to life adversities and requiring assistance by the governmental social service (n?=?39), as compared with normal controls (n?=?36). The Gudjonsson Suggestibility Scale 2 was administered to participants in a battery including measures of memory capacity, verbal ability, depression, and anxiety. The finding showed that the ‘assisted’ children were significantly more suggestible than the controls with a large effect size for Yield 1 and total suggestibility. In addition, IS was negatively correlated with verbal memory and ability, but not with anxiety and depression. The two groups differed as to their level of total suggestibility after adjusting for verbal ability. Implications of the findings for the forensic assessment of vulnerable subjects are discussed.     

Effects of personality,interrogation techniques and plausibility in an experimental false confession paradigm

Purpose. The goal of the present study was to investigate the effects of personality variables, interrogation techniques and the plausibility level of an alleged transgression on the experimental elicitation of false confessions. Methods. Two hundred and nineteen undergraduate students assessed on measures of compliance, self‐esteem, locus of control and interrogative suggestibility participated in the Kassin and Kiechel (1996) paradigm. Experimental manipulations included minimization and maximization interrogation techniques and high and low plausibility of the alleged typing mistake to examine rates of false confession and internalization. Results. The overall false confession and internalization rates across all conditions were 43 and 10%, respectively. An increased likelihood of false confession behaviour was associated with higher Shift scores on the Gudjonsson Suggestibility Scale, the use of minimization interrogation techniques and an increase in the plausibility of the allegation. Females were more likely to falsely confess than males in the high plausibility condition, whereas Caucasian and Asian participants were equally likely to falsely confess. Personality variables, such as compliance, most influenced the behaviour of males and Asians. Conclusions. The results of this study offer insight into false confession behaviour, suggesting that individuals who have a tendency to change their responses in the face of negative feedback may be more prone to false confession behaviour. The findings also serve to highlight the dangers of using minimization interrogation techniques and elucidate the limited generalizability of the paradigm to situations in which the alleged transgression is less plausible.     

Interrogative suggestibility,self‐esteem,and the influence of negative life‐events

Purpose. Past research has frequently demonstrated the impact of life adversity on the behaviour and mindset of individuals. In terms of the formal police interview, the experience of negative life‐events may have an effect upon interviewee performance. This study, therefore, aims to investigate how negative life‐events may influence interviewee performance on the Gudjonsson suggestibility scale (GSS). Moreover, self‐esteem will also be investigated in relation to both the experience of negative life‐events and interrogative suggestibility. Method. Sixty participants were administered the GSS1. In between the immediate and delayed recall phases, interviewees were asked to complete the culture‐free self‐esteem inventory, the life‐events questionnaire and the Eysenck personality questionnaire. Results. Negative life‐events (NLEs) were significantly correlated with all of the GSS suggestibility scores (yield 1, yield 2, shift and total Suggestibility). Contrary to past research, however, self‐esteem scores were not significantly related to any of the GSS components or to NLE scores. Conclusion. This paper is the first to show a link between the experience of NLEs and GSS scores. The findings suggest that interviewees reporting a high number of NLEs are significantly more susceptible to the leading questions, as well as to negative feedback, administered during the GSS interview. Erroneous reports and false confessions may thus be more likely with such interviewees, potentially classifying them as vulnerable witnesses.     

The Impact of Psychological Injuries on Sexual Harassment Determinations

Although a plethora of studies focus on jury decision making in sexual harassment cases, few studies examine damage award assessments in such suits, and even fewer explore the impact of psychological injury on jurors’ liability and damage award assessments. In the present study, 342 undergraduates read a hostile environment sexual harassment case that manipulated the plaintiff’s psychological injury level (severe vs. mild vs. control) to investigate whether males and females made different damage decisions. Males using a reasonable person standard found more liability as the severity of the plaintiff’s psychological injury increased. However, males using a reasonable woman standard found less liability with the addition of any psychological injury information. Similarly, for mild and severe injuries, males using the reasonable woman standard awarded lower damages than males using the reasonable person standard. Females tended to find more harassment than males, but psychological injury and legal standard had little impact on females’ legal decisions. We discuss these findings in light of the positive relationship often observed between the plaintiff’s injury severity level and pro-plaintiff verdicts.     

The Role of Suggestibility in Determinations of Miranda Abilities: A Study of the Gudjonsson Suggestibility Scales

Traditionally, high levels of suggestibility have been widely assumed to be linked with diminished Miranda abilities, especially in relationship to the voluntariness of waivers. The current investigation examined suggestibility on the Gudjonsson Suggestibility Scales in a multisite study of pretrial defendants. One important finding was the inapplicability of British norms to American jurisdictions. Moreover, suggestibility appeared unrelated to Miranda comprehension, reasoning, and detainees’ perceptions of police coercion. In testing rival hypotheses, defendants with high compliance had significantly lower Miranda comprehension and ability to reason about exercising Miranda rights than their counterparts with low compliance. Implications of these findings to forensic practice are examined.     

Child and adult witnesses with intellectual disability: The importance of suggestibility

Purpose. The main aim of the study was to examine the relationship between learning (intellectual) disability and interrogative suggestibility among children (11‐12 years old) and adults. Method. The Gudjonsson Suggestibility Scale (GSS 2) was administered to 110 children and 221 adults who were categorized into three groups according to fullscale IQ scores: (1) normal IQ (>75); (2) mild impairment (IQ score 55‐75); and (3) moderate impairment (IQ score <55). Results. Highly significant differences in memory and suggestibility emerged in both the child and adult samples across groups. Using memory as a covariate in the analysis eliminated the significant group differences for ‘yield 1’ among the children, but not for adults. There was no significant influence of memory on ‘shift’ in either group. Whereas ‘shift’ was significantly influenced by intellectual disability in children, no significant difference emerged across groups among adults. Conclusions. Children and adults with learning disability have much poorer memory and higher suggestibility scores than their contemporariesof normal intelligence. Differences in suggestibility are only partly explained by poorer memory scores. The findings reveal important differences between children and adults with intellectual disabilities. Children with learning disabilities are more susceptible to altering their answers under pressure than are adults with learning disabilities.     

Factors moderating physical and psychological symptoms of battered women

Physical and psychological symptoms of battered women were investigated based on the theory that their ongoing victimization would produce stress-related symptoms. It was hypothesized that moderating variables (e.g., frequency and severity of abuse, predictability and controllability of abuse, social support networks) would influence the effects of abuse. Battered women (N = 234) were interviewed according to a structured format which allowed for behavioral indices of the data and categorization of the women's responses. Results indicated that frequency of abuse was a strong predictor of the number and severity of symptoms. Those women who could predict abuse experienced more symptoms. Severity of physical and psychological symptoms was predicted by a model including women with more injuries requiring medical attention, women adhering to traditional sex role values, and the presence of one type of emotional abuse. Battered women perceived their physical and emotional health as deteriorating during the relationship and during the abuse, but as getting healthier after the abuse ended. Future research needs to replicate these findings with a representative group of battered women who are still in the battering relationship.     

Associations between expectancies of alcohol and drug use, severity of partner violence, and posttraumatic stress among women

Women who experience recurrent intimate partner violence (IPV) may use alcohol or drugs because they expect that these substances will help them cope with the negative physical and psychological sequelae of IPV. However, expectancies for alcohol and drug use have not been explored among this population of women. We used the Relaxation and Tension-Reduction Scale, Arousal and Aggression Scale, and Social Assertion Scale of the Alcohol Expectancy Questionnaire and modified its items to assess both alcohol and drug expectancies of 212 community-based, IPV-exposed women. Results of bivariate correlations showed that greater alcohol and drug expectancies were significantly correlated with greater alcohol problems and greater posttraumatic stress total and symptom severity scores. Results of a multivariate regression model showed that after controlling for demographic characteristics and history of childhood trauma, Relaxation and Tension- Reduction expectancies were associated with number of days of alcohol use, alcohol problems, physical and sexual IPV severity scores, and posttraumatic stress total and reexperiencing symptom severity scores. Expectancies do not significantly moderate the relationships between IPV, posttraumatic stress, and problematic alcohol and drug use. Given the strong relationships of expectancies with IPV severity, posttraumatic stress, and alcohol problems, expectancies may serve as targets for interventions to reduce alcohol use and problems and improve health-related outcomes in IPV-exposed women.     

Shortened versions of the Gudjonsson Suggestibility Scale meet the standards

Purpose. The Gudjonsson Suggestibility Scale (GSS; Gudjonsson, 1984, 1997 ) is a well‐established forensic tool for measuring interrogative suggestibility. However, one restriction of this tool is that it requires an extensive testing procedure. The present study examined whether shorter versions of the GSS yield similar results as the original GSS procedure. Methods. One group (N=20) was given a shortened version of the GSS that consisted of an immediate recall test and the specific questions. GSS scores in this group were compared with those in a group (N=20) that had the standard procedure which includes a retention interval and immediate and delayed recall tests. A third group (N=20) was administered a shortened procedure in which the 20 GSS questions immediately followed the GSS story. In the fourth group (N=20), participants were given the retention interval, but no recall tests were administered. Results. ANOVA showed no differences in GSS scores amongst the four groups. Post hoc power analyses indicated that these non‐significant findings were not the result of a power problem and that larger sample sizes are expected to yield comparable results. Further analyses showed that neither the retention delay nor the recall tests affected suggestibility scores. Conclusions. These results suggest that shortened procedures for administering the GSS may be employed in situations where time is a key factor.     

Prevalence of trauma, PTSD, and dissociation in court-referred adolescents

This study examines the prevalence of trauma, posttraumatic stress disorder (PTSD), and dissociative symptoms in adolescents. The sample consisted of 76 females and 76 males, between the ages of 12 and 18, referred to the Child Guidance Clinic of the Superior Court of the District of Columbia for a psychological evaluation. Two sets of analyses were conducted. One set included the entire sample; the second set excluded those individuals whose listed referral problem included only being a victim of abuse. Results of the study suggest a high prevalence of trauma in both genders; however, females had significantly higher rates than those reported in males. Similarly, female adolescents demonstrated significantly higher prevalence rates of PTSD symptoms compared with their male counterparts in the entire sample and showed a trend toward significance in the analysis of the subsample. There was a low prevalence of dissociative symptoms across both genders.     

Childhood sexual abuse, gender, and depression among incarcerated youth

This study examined whether sexual abuse was related to higher levels of psychological distress among incarcerated youth and if the effects were invariant across gender. Participants were male and female adolescents, aged 11 to 20 years, incarcerated in six juvenile correctional institutions in five states. Using data from a national study of juveniles confined to secure institutions, this study assessed the relationship between gender, sexual abuse, and depression. Adolescents who were sexually abused during childhood compared to adolescents who were not report higher levels of depression. Sexually abused girls and boys report higher levels of depression compared to boys not sexually abused. These findings suggest the importance of understanding the relationship between childhood sexual abuse and depressive symptoms among incarcerated youth. Additionally, the findings suggest that the effects of childhood sexual abuse are similar for males and females among a high-risk sample of institutionalized juvenile delinquents. Implications for treatment of incarcerated youth are discussed.
