Differentiating suicide attempters from suicide ideators using the Integrated Motivational-Volitional model of suicidal behaviour.

BACKGROUND Suicidal behaviour is a significant public health concern, yet little is known about the factors that enable or impede behavioural enactment (engaging in a suicide attempt). AIMS Drawing on the Integrated Motivational-Volitional (IMV) Model of Suicidal Behaviour (2011), this study examined the factors associated with having thoughts of suicide (ideation) versus those associated with suicide enaction (attempts). Within a multivariate context, it was predicted that the factors associated with ideation formation (motivational factors) would be distinct from those factors which governed behavioural enaction (volitional moderators). METHOD Healthy adults (N=1, 288) completed an anonymous self-report survey. Analyses compared three groups: suicide attempters (n=230), suicide ideators (n=583), and those without any suicide history (n=475). RESULTS Suicide attempters differed from suicide ideators on all volitional factors (fearlessness about death, impulsivity, and exposure to suicidal behaviour), with the exception of discomfort tolerance. Compared to ideators, attempters were more likely to have a family member and close friend who had self-injured or attempted suicide, and were more impulsive and fearless about death. Conversely, the two suicide groups did not differ on any of the variables (motivational factors) associated with the development of thoughts of death by suicide. LIMITATIONS This is a cross-sectional study based on self-report measures. CONCLUSIONS Further research efforts to distinguish between suicide ideators and suicide attempters is crucial to inform the development of intervention and treatment approaches.

Psychopathy and criminal behaviour: a psychosocial research perspective

Purpose – This paper aims to provide a critical review of the psychopathy literature, with a particular focus on recent research examining the relationship between psychopathy and various forms of criminal behaviour.Design/methodology/approach – The authors provide an overview of the studies conducted to date. To identify relevant published studies for this review, literature searches were completed using Web of Science, Scopus, PsychINFO, and PubMed.Findings – Substantial empirical research exists to suggest that psychopathy is a robust predictor of criminal behaviour and recidivism. Furthermore, considerable support for the assertion that the violence perpetrated by psychopathic offenders is more instrumental than the violence committed by other offenders was found. In addition, some research suggests that the greater use of instrumental violence among psychopathic offenders may be due to the interpersonal/affective traits of psychopathy, and not the impulsive/antisocial traits.Originality/value – The c...

Teachers’ self-efficacy beliefs, self-esteem, and job stress as determinants of job satisfaction

Purpose – The purpose of this paper is to examine the role of teaching self-efficacy, perceived stress, self-esteem, and demographic characteristics (age, gender, education, and years of teaching experience) in predicting job satisfaction within a sample of 121 Irish primary school teachers. Design/methodology/approach – Survey data were collected from teachers from eight primary schools. Hypotheses were tested using a comparison of means, correlations, and multiple regression. Findings – Results indicated that the predictor variables accounted for 22 per cent of variance in teachers’ job satisfaction. However, only perceived stress was found to explain unique predictive variance, with high levels of occupations stress related to low levels of job satisfaction. Practical implications – Perceived stress should be targeted in efforts to improve teachers’ job satisfaction. Originality/value – The results make an additional contribution to the literature by providing important information on the factors contr...

A bifactorial solution to the psychopathy checklist screening version in a sample of civil psychiatric patients

BACKGROUND There is considerable debate about the underlying factor structure of the Psychopathy Checklist: Screening Version (PCL: SV). An established view is that it reflects a unitary construct underpinned by two correlated factors. More recent research has, however, undermined this conceptualisation. AIMS Our aim was to compare 10 competing models of the PCL: SV in a sample of civil psychiatric patients. METHOD Ten distinct factor models were specified and tested using conventional confirmatory factor analytic techniques, along with confirmatory bifactor modelling. RESULTS A bifactor model, including two general factors (interpersonal-affective and antisocial-lifestyle), and four subordinate factors (interpersonal, affective, antisocial and lifestyle) provided the best fit to the data. The reliability of the conceptualisation was supported through the use of composite reliability, and the differential relationships exhibited between the general factors and measures of personality, impulsivity and mental health. CONCLUSIONS Our findings provide further weight to taking the two general psychopathy factors into account when interpreting the PCL: SV for clinical purposes. Copyright

The Role of Psychopathy and Exposure to Violence in Rape Myth Acceptance

The main aim of the present study was to specify and test a structural model to examine the relationships between four psychopathy dimensions (Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Antisocial Behavior), childhood exposure to violence, and rape myth acceptance while controlling for gender, age, sample type (prisoner vs. non-prisoner), and relationship status. Participants were a sample of non-offending adults (n = 319) recruited from the University of Security in Poznan, and a sample of prisoners (n = 129) incarcerated in Stargard Szczecinski Prison. Results indicated that the model provided a good fit for the data, and that Callous Affect and childhood exposure to violence had a significant positive effect on attitudes toward rape and rape victims. Theoretical and practical implications of our findings are discussed.

Psychopathy, intelligence and emotional responding in a non-forensic sample: an experimental investigation

This study examined the relationships between psychopathy (primary and secondary), intelligence and emotional responding in a sample of 50 university students, using a task measuring autonomic responses to 40 pictorial stimuli (20 neutral and 20 emotionally provoking). Results indicated no significant direct relationship between primary or secondary psychopathy and emotional response, or primary or secondary psychopathy and intelligence. However, a significant moderating effect of intelligence on the association between both psychopathy factors and emotional response was observed, indicating those scoring higher on psychopathy but with lower intelligence portray the expected emotional responses to the affective stimuli (primary: β = −.56, p < .05; secondary: β = .80, p < .001). These findings indicate abnormal reactivity to emotional stimuli in lower intelligence, higher psychopathic individuals, and suggest differing roles for the two facets of psychopathy in affective responsiveness deviations.

A structural test of the Integrated Motivational-Volitional model of suicidal behaviour.

Suicidal behaviours are highly complex, multi-determined phenomena. Despite this, historically research has tended to focus on bivariate associations between atheoretical demographic and/or psychiatric factors and suicidal behaviour. The aim of this study was to empirically test the Integrated Motivational-Volitional model of suicidal behaviour using structural equation modelling. Healthy adults (N=1809) completed anonymous self-report surveys. The fit of the proposed model was good, and explained 79% of variance in defeat, 83% of variance in entrapment, 61% of variance in suicidal ideation, and 27% of variance in suicide attempts. All proposed paths were significant except for those between goal re-engagement and two factors of suicide resilience (Internal Protective and External Protective) and suicidal ideation; and impulsivity and discomfort intolerance and suicide attempts. These findings represent a preliminary step towards greater clarification of the mechanisms driving suicidal behaviour, and support the utility of basing future research on the Integrated Motivational-Volitional model of suicidal behaviour.

The Integrated Psychosocial Model of Criminal Social Identity (IPM-CSI)

ABSTRACT The integrated psychosocial model of criminal social identity attempts to synthesize, distill, and extend our knowledge and understanding of why people develop criminal social identity, with a particular focus on the psychological and social factors involved. We suggest that the development of criminal social identity results from a complex interplay between four important groups of psychosocial factors: (1) an identity crisis that results in weak bonds with society, peer rejection, and is associated with poor parental attachment and supervision; (2) exposure to a criminal/antisocial environment in the form of associations with criminal friends before, during, and/or after incarceration; (3) a need for identification with a criminal group in order to protect one’s self-esteem; and (4) the moderating role of personality traits in the relationship between criminal/antisocial environment and the development of criminal social identity. The model produces testable hypotheses and points to potential opportunities for intervention and prevention. Directions for future research are discussed.

Empirically Derived Subgroups of Self-Injurious Thoughts and Behavior: Application of Latent Class Analysis.

Latent class analysis was applied to the sample data to identify homogenous subtypes or classes of self-injurious thoughts and behavior (SITB) based on indicators indexing suicide ideation, suicide gesture, suicide attempt, thoughts of nonsuicidal self-injury (NSSI), and NSSI behavior. Analyses were based on a sample of 1,809 healthy adults. Associations between the emergent latent classes and demographic, psychological, and clinical characteristics were assessed. Two clinically relevant subtypes were identified, in addition to a class who reported few SITBs, and were labeled as follows: low SITBs (25.8%), NSSI and ideation (25%), and suicidal behavior (29.2%). Several unique differences between the latent classes and external measures emerged. For instance, those belonging to the NSSI and ideation class compared with the suicidal behavior class reported lower levels of entrapment, burdensomeness, fearlessness about death, exposure to the attempted suicide or self-injury of family members and close friends, and higher levels of goal disengagement and acute agitation. SITBs are best explained by three homogenous subgroups that display quantitative and qualitative differences. Profiling the behavioral and cognitive components of suicidal and nonsuicidal self-injury is potentially useful as a first step in developing tailored intervention and treatment programs.

Can We Use Hare’s Psychopathy Model within Forensic and Non-Forensic Populations? An Empirical Investigation

ABSTRACT Although psychopathy construct (Self-Report Psychopathy Scale–Short Form [SRP–SF]) was assessed among various samples, prior research did not investigate whether the model proposed by Hare and colleagues can be used to capture psychopathy scores derived from forensic and nonforensic populations. The main objective of the current study was to test dimensionality, construct validity, and factorial invariance of the SRP–SF within prison (n = 730) and student (n = 2,506) samples. Our results indicate that the SRP–SF measure cannot be used in the same way within forensic and nonforensic samples, which may be due to the inclusion of criminal/antisocial traits as an integral part of psychopathy.
