Construct validity of the Beck Hopelessness Scale (BHS) among University Students: A multitrait–multimethod analysis.

There is considerable debate about the underlying factor structure of the Beck Hopelessness Scale (BHS) in the literature. An established view is that it reflects a unitary or bi-dimensional construct in non-clinical samples. There are, however, reasons to reconsider this conceptualisation. Based on previous factor analytic findings from both clinical and non-clinical studies, the aim of the present study was to compare 16 competing models of the BHS in a large university student sample (N = 1, 733). Sixteen distinct factor models were specified and tested using conventional confirmatory factor analytic techniques, along with confirmatory bifactor modelling. A 3-factor solution with 2 method effects (i.e., a multitrait–multimethod model) provided the best fit to the data. The reliability of this conceptualisation was supported by McDonald's coefficient omega, and the differential relationships exhibited between the three hopelessness factors (‘Feelings about the Future’, ‘Loss of Motivation’, and ‘Future Expectations’) and measures of goal disengagement, brooding rumination, suicide ideation, and suicide attempt history. The results provide statistical support for a three-trait and two-method factor model, and hence the three dimensions of hopelessness theorised by Beck. The theoretical and methodological implications of these findings are discussed

Improvement of Learning and Memory of Mice by Plumbagin

Roots of Plumbago zeylanica have been reported to improve learning and memory of mice, but the effect of plumbagin on learning and memory of mice and the possible mechanisms for its effect on memory have not been explored till date. So the present study was designed to evaluate the effect of plumbagin on learning and memory of Swiss young male albino mice. Plumbagin (4, 8, 16 mg/kg, p.o.) and physostigmine (0.1 mg/kg,i.p.) per se were administered for 15 successive days to separate groups of mice. Behavioral parameters of learning and memory were recorded using Morris water maze. Acetylcholinesterase activity was estimated in brain of mice. Effect of plumbagin on scopolamine (0.4 mg/kg, i.p.) and diazepam (1 mg/kg, i.p.)-induced amnesia was also investigated. Locomotor activities of mice were also recorded. Plumbagin (8 and 16 mg/kg) and physostigmine significantly improved learning and memory of mice, as indicated by decrease in escape latency during training and increase in time spent in target quadrant of Morris water maze during retrieval. The drugs did not show any significant effect on locomotor activities of mice. Memory improving activity of plumbagin (16 mg/kg) was equivalent to physostigmine. Plumbagin significantly reversed scopolamine- and diazepam- induced amnesia in mice. Plumbagin and physostigmine also significantly reduced brain acetylcholinesterase activity of mice. In conclusion, plumbagin significantly improved memory of mice possibly through inhibition of brain acetylcholinesterase activity and through involvement of GABA-benzodiazepine pathway. Thus, plumbagin may be explored further for management of cognitive dysfunction

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

The integrated psychosocial model of criminal social identity attempts to synthesize, distil, 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 of four important groups of psychosocial factors: (1) an identity crisis which 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

Criminal social identity and suicide ideation among Pakistani young prisoners.

© Emerald Group Publishing Limited. Purpose: Suicidal behaviour is a common in prisoners, yet little is known about the factors that may protect against thoughts of ending one's life. The purpose of this paper is to specify and test a structural model to examine the relationship between three criminal social identity (CSI) dimensions (in-group affect, in-group ties, and cognitive centrality) and suicide ideation while controlling for period of confinement, age, criminal friends, and offense type (violent vs non-violent). Design/methodology/approach: Participants were 415 male juvenile offenders incarcerated in prisons in Khyber Pakhtunkhwa Pakistan. A structural model was specified and tested using Mplus to examine the relationships between the three factors of CSI and suicidal thoughts, while controlling for age, offender type, period of confinement, and substance dependence. Findings: The model provided an adequate fit for the data, explaining 22 per cent of variance in suicidal thoughts. In-group affect (the level of personal bonding with other criminals) was found to exert a strong protective effect against suicide ideation. Originality/value: The research contributes important information on suicide ideation in Pakistan, an Islamic country in which suicide is considered a sin and subsequently a criminal offence. Results indicate that Juvenile offenders' sense of shared identity may help to prevent the development of thoughts of death by suicide. Consequently, separating and isolating young prisoners may be ill advised

Latent classes of delinquent behaviour associated with criminal social identity among juvenile offenders in Pakistan

© Emerald Group Publishing Limited. Purpose – The purpose of this paper is to examine the number and nature of latent classes of delinquency that exist among male juvenile offenders incarcerated in prisons in Pakistan. Design/methodology/approach – The sample consisted of 415 young male offenders incarcerated in prisons in Khyber Pakhtunkhwa (KPK) Pakistan. Latent class analysis was employed to determine the number and nature of delinquency latent classes. Multinomial logistic regression was used to estimate the associations between latent classes and the three factors of criminal social identity (cognitive centrality, in-group affect, and in-group ties) whilst controlling for criminal friends, period of confinement, addiction, age, and location. Findings – The best fitting latent class model was a three-class solution. The classes were labelled: “minor delinquents” (the baseline/normative class; Class 3), “major delinquents” (Class 1), and “moderate delinquents” (Class 2). Class membership was predicted by differing external variables. Specifically, Class 1 membership was related to having more criminal friends; while Class 2 membership was related to lower levels of in-group affect and higher levels of in-group ties. Practical implications – Findings are discussed in relation to refining current taxonomic arguments regarding the structure of delinquency and implications for prevention of juvenile delinquent behaviour. Originality/value – First, most previous studies have focused on school children, whereas, this paper focuses on incarcerated juvenile offenders. Second, this research includes delinquents from Pakistan, whereas, most previous research has examined delinquent behaviour in western cultures

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

Can we use Hare’s psychopathy model within forensic and non-forensic populations? An empirical investigation

Although psychopathy construct (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 non-forensic 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 non-forensic samples, which may be due to the inclusion of criminal/antisocial traits as an integral part of psychopathy

Gender Differences in Risk and Protective factors for Resolved Plans and Preparations for Suicide among University Students

Background. Identifying the psychological predictors of suicide risk is essential because these variables may be amenable to change in treatment, unlike demographic or historical factors. Aims. The aim of this study was to examine the predictors of past two-week suicidal ideation for males and females separately. Method. Participants were 1184 healthy adults who completed an online survey. Results. A significant association between suicidal ideation and gender was found, such that mean levels were significantly higher in females than males. Separate regression analyses accounted for significant amounts of variance in suicide ideation, 54% for males and 68% for females. Moreover, the analyses revealed that suicide resilience Factor 2 (Emotional Stability) was a protective factor for both males and females; however, defeat, goal disengagement, and depression were independently associated with suicide ideation in males but not females. By contrast, entrapment, perceived burdensomeness, and hopelessness Factor 3 (Future Expectations) were significant risk factors only in females. Conclusions. The findings have clinical and practical implications, which may guide future practice, and supports the notion of targeted prevention and intervention strategies
