Psychometric Proprieties and Construct Validity of the Brother-Sister Questionnaire in a Sample of Portuguese Adolescents

The Brother-Sister Questionnaire (BSQ; Graham-Bermann and Cutler 1994) is an instrument designed to measure qualities of sibling relationships. Aim: In the present study the main objective was to examine the psychometric properties and validity construct of BSQ - Portuguese version. Data were collected among 197 adolescents. The Cronbach’s alpha of the four domains ranged from .58 to .84. The psychometric characteristics of BSQ Portuguese version were found to be adequate. The results confirm the multi-dimensional model composed of four factors proposed by the authors of this instrument, as well as their suitability to assess quality of Portuguese sibling relationships. The BSQ offers a reliable and valid measure to be used within Portuguese population.     

Validity and reliability of the Self-Report Delinquency among a sample of at-risk youths

Self-Report Delinquency scales have formed the basis of much understanding of juvenile delinquency today, but further improvement and extensive measurement research on self-report measures of crime are needed. The present study examined the psychometric properties of the shorter general delinquency scale version of the classic commonly used Self-Report of Delinquency (SRD) measure created for the original National Youth Survey (NYS) using a sample (N = 412) of male (n = 200) and female (n = 212) at-risk Portuguese youths. The shorter version of the SRD demonstrated satisfactory validity and reliability, namely in terms of its latent one-factor structure, internal consistency, convergent validity, divergent validity, concurrent criterion validity and discriminant groups validity that overall justifies its use among this population. The shorter general delinquency scale version of the SRD is a valid and reliable measure from a modern psychometric perspective that can be used with at-risk youths.     

Internal reliability and construct validity of the Novaco Anger Scale-1998-S in a sample of violent prison inmates in Sweden

Abstract

In this study, the internal reliability and construct validity of the recently adapted Swedish version of the Novaco Anger Scale (NAS-1998-S; Lindqvist, Dåderman, & Hellström, Social Behavior and Personality, 8, 773–788, 2003), as well as its scale correlations with demographic and criminality variables, were investigated. Construct validity was established by assessing the correlation pattern of the scales of NAS-1998-S with concurrent scales of similar and distinct constructs. Ninety-five male violent prisoners, ranging in age from 18 to 67 years, participated. The results demonstrated good internal reliability, consistent intrascale relationships, and appropriate construct validity of NAS-1998-S. The number of previous convictions had a moderate negative relationship with the capacity of control. Age and education correlated negatively with the NAS-1998-S scales, except Regulation. In addition to psychometric issues, the results were discussed from a clinical perspective on the offender population.     

Should Abused Women's Reports of Partner Substance Abuse Be Accepted as Valid?

Current research suggests that a husband's substance abuse is correlated with severity of physical abuse and the woman's decision to leave a violent situation. Often, only the battered woman's report of abuse is available. This study compares women's reports of their partners' substance use/abuse with their partners' report using a brief measure of polydrug and alcohol abuse, the Substance Abuse Subtle Screening Inventory (SASSI) and the Conflict Tactics Scale (CTS). Data were analyzed for 25 recovery couples and 25 nonrecovery couples. The correlations for all 50 couples between the male's reported use and the female's report of her partner's use on the SASSI and the CTS were significant on all but one of the CTS scales. They ranged on SASSI from .73 to .33 and from .31 to .06 on the CTS. This suggests that the SASSI and possibly the CTS could be used as valuable tools for assessing women's reports of their partner's substance use/abuse.     

The Effect of Question Order on Disclosure of Intimate Partner Violence: An Experimental Test Using the Conflict Tactics Scales

Two plausible but contradictory approaches to question order in research on sensitive or criminal behavior are (1) that presenting the questions in a sequence corresponding to a culturally recognized behavior pattern will facilitate disclosure, and (2) that presenting questions in random order will result in more disclosure because random order disrupts response sets. The question order of the original Conflict Tactics Scales (CTS1) used the culturally recognized sequence approach, and the revised CTS (CTS2) used a modified random order. This experiment was designed to determine which of these two question orders results in more disclosure of physical and sexual assault of a dating partner. The standard version of the CTS2, which has the questions from each of the 5 scales interspersed in a slightly modified random order, was administered to every second student in a sample of 417 university students. The other half of the sample were given the same instrument but with the questions in the culturally recognized sequential order used in the CTS1. The cultural sequence order begins with the socially approved behaviors in the Negotiation scale and ends with scales measuring antisocial and the criminal behavior such as the Physical Assault scale. The results indicate that the CTS2 random order produced significantly higher disclosure rates for the scales that measure criminal behavior (Physical Assault, Injury, and Sexual Coercion) and made no difference for the other CTS2 scales (Negotiation and Psychological Aggression). Although these results suggest that the CTS2 random order is the preferred approach, reasons to treat that conclusion with caution are presented.     

Measuring violence risk and outcomes among Mexican American adolescent females

Central to the development of culturally competent violence prevention programs for Hispanic youth is the development of psychometrically sound violence risk and outcome measures for this population. A study was conducted to determine the psychometric properties of two commonly used violence measures, in this case for Mexican American adolescent females. The Conflict Tactics Scales (CTS2) and the Past Feelings and Acts of Violence Scale (PFAV) were analyzed to examine their interitem reliability, criterion validity, and discriminant validity. A sample of 150 low-risk and 150 high-risk adolescent females was studied. Discriminant validity was indicated by the perpetrator negotiation scale and by the victim psychological aggression and sexual coercion scales of the CTS2 and the PFAV. Analysis indicates that the CTS2 scales and the PFAV demonstrate adequate reliability, whereas strong criterion validity was evidenced by eight of the CTS2 scales and the PFAV.     

Adaptation of the Basic Empathy Scale among a Portuguese sample of incarcerated juvenile offenders

The main aim of the present study was to examine the psychometric properties of the Basic Empathy Scale (BES) and of its adapted short version among a forensic sample of incarcerated male juvenile offenders (N = 221). The Portuguese validations of the BES and its adapted short version demonstrated good psychometric properties, namely in terms of the two-factor structure, internal consistency, convergent validity, discriminant validity, and concurrent validity that generally justifies its use among this population. Statistically significant associations were found with callous–unemotional traits and social anxiety. Findings are discussed in terms of the use of the BES and its adapted short version with juvenile offenders.     

Adaptation of the Narcissistic Personality Inventory among a Portuguese sample of incarcerated juvenile offenders

The aim of the present study was to assess the psychometric properties of the Narcissistic Personality Inventory (NPI) and two of its short forms (NPI-16 and NPI-13) among a Portuguese sample of male incarcerated juvenile offenders (N?=?221). Of these, only the NPI-13 short version demonstrated a good fit in terms of its factor structure. The NPI-13 also showed promising psychometric properties in terms of its internal consistency, convergent validity, discriminant validity, and criterion-related validity. Statistically significant associations were found with age of crime onset, crime seriousness, conduct disorder symptoms, alcohol abuse, and cannabis use. These findings justify the use of the NPI-13, especially its Entitlement/Exploitativeness dimension, among incarcerated male youths.     

Psychometric properties of the Barratt Impulsiveness Scale version 11 among a Portuguese sample of incarcerated juvenile offenders

The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a forensic sample of incarcerated male juvenile offenders (N?=?221). Principal Component Analysis with Promax rotation revealed the expected 6-factor structure, but Confirmatory Factor Analysis of the 6-factor first-order and the 3-factor second-order factorial structures did not present sufficiently good fits. Despite that, the Portuguese adaptation of the BIS-11 demonstrated generally acceptable psychometric properties in terms of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and concurrent validity that justifies its use among the youth forensic population. Statistically significant associations were found with age of crime onset, conduct disorder, crime seriousness, alcohol use and drug use.     

The Self-Report Symptom Inventory (SRSI): a New Instrument for the Assessment of Distorted Symptom Endorsement

Self-report instruments to detect distorted symptom reporting play a crucial role in clinical and forensic psychology. Most of the instruments currently available for this purpose only list implausible symptoms, which makes them easily identifiable as symptom validity tests. We developed the Self-Report Symptom Inventory (SRSI), combining five self-report scales of genuine symptoms with five pseudosymptom scales to screen for distorted symptom reporting in various domains (e.g., depression, post-traumatic stress). With a preliminary questionnaire version, we collected data in a heterogeneous sample (N?=?239) and performed an item selection, resulting in the final 107-item version. This version was evaluated in civil forensic patients, inmates of a prison, and a population-based sample; N?=?387). Data show that (a) SRSI pseudosymptom scores correlate highly (≥.80) with other instruments tapping distorted symptom endorsement, notably the Structured Inventory of Malingered Symptomatology; (b) High SRSI pseudosymptom scores tend to correlate with underperformance; and (c) The psychometric features of the SRSI are satisfactory, with internal consistency for the total scales >.90 and retest reliability >.85. The instrument appears to be a promising tool for examining symptom exaggeration, but further work is required, in particular cross-validation with other samples and different methods.     

The Development of a Reduced-Item Structured Inventory of Malingered Symptomatology (SIMS)

Effort assessment is a relevant area in neuropsychological assessment. There are well-established self-report measures, such as the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) FBS Symptom Validity Scale (FBS; Lees-Haley, English & Glenn, Psychological Reports 68: 203-210, 1991) and MMPI-2 Response Bias Scale (RBS; Gervais, Ben-Porath, Wygant & Green, Assessment 14: 196, 2007). However, there is also a need for brief measures of symptom exaggeration. The Structured Inventory of Malingered Symptomatology (SIMS) appears to be a promising self-report measure of symptom validity (e.g., Smith & Burger, Academy of Psychiatry and the Law 25: 183-189, 1997). In order to understand the psychometric properties of the SIMS, a comprehensive item analysis was performed with the questionnaire. Items were removed due to invariable response or lack of relationship with the total SIMS. Receiver operating characteristics (ROC) curve analyses were completed using RBS and FBS Symptom Validity Scale (FBS) of the MMPI-2 with items grouping from the SIMS indices. The results found that limiting the number of items did not affect overall utility. The abbreviated indices on the SIMS had excellent discrimination with the neurologic impairment (NI) and affective disorder (AF) scales and good discrimination with psychosis (P) and amnesic disorder (AM) scales of the SIMS. The briefer measure allows for less time required to administer the measure, while still maintaining the integrity of the SIMS.     

Detecting Domestic Violence: Italian Validation of Revised Conflict Tactics Scale (CTS-2)

Intimate partner violence (IPV) is a public health problem that requires valid assessment tools. The aim of the study is to evaluate the psychometric properties of the Italian version of the revised Conflict Tactics Scale (CTS-2) in a sample of 209 women (143 from the general population and 66 IPV victims). Based on factor analysis, five subscales were proposed, partially corresponding to the original scales: negotiation, violence, extreme violence, injury, and sexual coercion. The reliability of the subscales was good, ranging from 0.78 to 0.96. The discriminant capacity of the scores was assessed comparing victims versus non-abused women, and extreme violence correlated positively with depression, injury and negotiation but negatively with alexithymia. These results indicate that the Italian version of CTS-2 scale can be recommended for use in research and clinical programs.     

The Portuguese adaptation of the Gudjonsson Suggestibility Scale (GSS1) in a sample of inmates

This paper comprises two studies which address the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scale, GSS1. In study 1, the means and standard deviations for the suggestibility results of a sample of Portuguese inmates (N = 40, M_age = 37.5 years, SD = 8.1) were compared to those of a sample of Icelandic inmates (Gudjonsson, 1997; Gudjonsson & Sigurdsson, 1996). Portuguese inmates' results were in line with the original results. In study 2, the means and standard deviations for the suggestibility results of the sample of Portuguese inmates were compared to those of a general Portuguese population sample (N = 57, M_age = 36.1 years, SD = 12.7). The forensic sample obtained significantly higher scores in suggestibility measures than the general population sample. ANOVA confirmed that the increased suggestibility in the inmates sample was due to the limited memory capacity of this latter group. Given that the results of both studies 1 and 2 are in keeping with the author's original results (Gudjonsson, 1997), this may be regarded as a confirmation of the validity of the Portuguese GSS1.     

Measuring motivation to change in offenders

Abstract

Measuring motivation to change in offender populations is important both for selection into treatment programmes and for assessing progress in therapy. Two studies are reported in this paper, both looking at the psychometric properties of questionnaires designed to measure stage of change in therapy. The samples used were patients detained in special hospitals under the Mental Health Act (1983) classification of psychopathic disorder. The first study provides norms for this group on the stages of change in psychotherapy questionnaire, plus some additional information on its relationship with self-esteem and self-efficacy measures. The second study looked at a brief version of the stages of change questionnaire, concluding that its psychometric properties were such that further use was contra-indicated.     

Intimate Partner Violence Control Scale: Development and Initial Testing

Although control has long been considered central to understanding intimate partner violence (IPV), there continues to be a notable lack of validated scales measuring control (e.g., Strauchler et al. Journal of Family Violence, 19(6), 339–354, 2004). The purpose of this study was to develop and empirically validate a brief assessment tool, the Intimate Partner Violence Control Scale (IPVCS), designed to measure control in the context of IPV. Data from a sample of male undergraduate and graduate students (n = 436) were used to examine the scale’s properties. After reviewing theoretical conceptualizations and measurement issues of control, psychometric properties of the IPVCS and results of exploratory hypotheses tests are presented. The availability of a brief and reliable measure of control offers a tool for professionals in the judicial system, for IPV victims’ advocates, and for human services workers in practice settings to adequately assess for control and fills a gap in this area of research and practice.     

Assessing child-safe culture and practices in organisational settings: a validation and refinement of Kaufman's Organisational Safety Climate Survey

ABSTRACT

Using an Australian sample of employees (n?=?1068) we assessed the psychometric properties of Kaufman’s Organisational Safety Climate Survey and its practical utility for measuring child-safe culture within organisations. The 60-item survey was found to have adequate psychometric properties. Initial factor analyses indicated a unidimensional factor structure, despite the survey being originally conceptualised into four subscales. Cronbach’s α coefficients were .95 for the full survey, with subscales ranging from .65–.94. However, qualitative feedback from respondents indicated that the survey was somewhat laborious and repetitive, with some item ambiguity noted. Refinements to the survey resulted in a 24-item short-form survey. The psychometric properties of the short-form survey were re-assessed. Factor analyses indicated a three-factor solution. Despite a significant reduction in items, internal consistency of the scale was not compromised; reliability of subscales also improved. Validation of this short-form survey as an alternative, time-efficient measure to maximise employee participation and contribution, is recommended.     

Association of the MMPI-2 Restructured Form (MMPI-2-RF) Validity Scales with Structured Malingering Criteria

The current study examined the validity scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Ben-Porath and Tellegen 2008) in relation to the structured malingering criteria developed to assess malingered neurocognitive dysfunction and pain-related disability. These criteria examined a sample of 251 individuals undergoing compensation-seeking evaluations, who completed a battery of response bias measures. The MMPI-2-RF over-reporting scales yielded large effect sizes in contrasting those in the probable/definite malingering groups from the incentive only groups. The largest effects were found for the Infrequent Responses and Gervais et al. (Assessment, 14, 196–208, 2007) Response Bias Scale, an experimental scale that can be scored on the MMPI-2-RF. Classification analyses were also utilized to examine various cut scores for the individual validity scales, as well as their use in combination. These results suggest that the MMPI-2-RF validity scales can be used to screen for malingering, as they exhibited good sensitivity at lower cutoffs. The implications of these results and their use in forensic evaluations are discussed.     

Security in the Interparental Subsystem (SIS) Scale: Psychometric Characteristics in a Sample of Portuguese Adolescents

The Security in the Interparental Subsystem Scale (SIS) is based on emotional security theory. This study examined the psychometric properties of an adaptation of the SIS to a sample of Portuguese adolescents (60.3 % girls; 10 to 18 years old; Mage?=?13 years; N?=?229), recruited in public schools. Discriminant and concurrent validity were assessed by analyzing SIS dimensions associations with adolescents’ exposure to interparental conflict (IC), and psychological adjustment, respectively. Exploratory and confirmatory factor analyses of the SIS supported a six-factor solution, with satisfactory internal consistency. Evidence for discriminant and concurrent validity was provided: most SIS dimensions significantly discriminated between adolescents exposed to higher vs. lower levels of IC; and a significant positive association between emotional reactivity and adolescents’ externalizing symptoms was found. These findings suggest that the SIS is a reliable tool for assessing adolescents’ emotional insecurity in the interparental relationship within the context of this sample.     

Test–Retest Reliability of the Revised Conflict Tactics Scales (CTS2)

The Revised Conflict Tactics Scales (CTS2) are widely used to measure intimate partner aggression. Various aspects of the CTS2 and its subscales have been examined, e.g. factor structure, internal consistency, and validity, but little or no evidence exists regarding the stability of the self-report of aggression on the CTS2 This study examines the stability of reports of aggression against a partner on the CTS2 among 82 men court-mandated to a batterer intervention program. At both testing times men reported on aggression occurring in the year prior to beginning treatment. Using variety scores, stability of report was strong for psychological aggression (r = 0.69), physical assault (r = 0.76), injury (r = 0.70), and negotiation (r = 0.60), but weaker for sexual coercion (r = 0.30). Implications for the use of the CTS2 in court-mandated populations are discussed.

The Justice Sensitivity Inventory: Factorial Validity, Location in the Personality Facet Space, Demographic Pattern, and Normative Data

This article investigates the psychometric properties of a self-report inventory for measuring individual differences in four components of justice sensitivity (JS): victim sensitivity, observer sensitivity, beneficiary sensitivity, and perpetrator sensitivity. A representative sample (N = 2510) was employed to (a) estimate the reliability of a newly developed perpetrator sensitivity scale, (b) test the factorial validity of this scale together with three previously developed scales (victim, observer, and beneficiary sensitivity), (c) estimate correlations between JS and demographic variables (gender, age, education, employment status, marital status, and residency in East versus West Germany), and (d) provide normative data for the computation of standard scores. A demographically heterogeneous convenience sample (N = 327) was used to locate the JS dimensions in the personality space of narrow facet factors. Results from confirmatory factor analyses demonstrated the factorial validity of the JS scales. Regression analyses with JS scales as criteria and personality facet scales as predictors suggested that JS cannot be reduced to combinations of personality facets. Demographic effects were small, explaining a maximum of 1.4% of JS variance. Women and East Germans were found to be more justice sensitive than men and West Germans, respectively. Victim sensitivity decreased with age; perpetrator sensitivity decreased with education. Taken together, our results corroborate the validity of the JS Inventory and contribute to a better psychological understanding of JS.
