Psychological Assessment

Meta-analysis of psychological assessment as a therapeutic intervention.
This study entails the use of meta-analytic techniques to calculate and analyze 18 independent and 52 nonindependent effect sizes across 17 published studies of psychological assessment as a therapeutic intervention. In this sample of studies, which involves 1,496 participants, a significant overall Cohen's d effect size of 0.423 (95% CI [0.321, 0.525]) was found, whereby 66% of treatment group means fell above the control and comparison group means. When categorical variables were taken into account, significant treatment group effects were found for therapy process variables (d = 1.117, [0.679, 1.555]), therapy outcomes (d = 0.367, [0.256, 0.478]), and combined process/outcome variables (d = 0.547, [0.193, 0.901]). These findings appear to be robust on the basis of fail-safe N calculations. Taken together, they suggest that psychological assessment procedures—when combined with personalized, collaborative, and highly involving test feedback—have positive, clinically meaningful effects on treatment, especially regarding treatment processes. They also have important implications for assessment practice, training, and policy making, as well as future research, which are discussed in the conclusion of the article.

WISC–III index score profiles of 520 Swedish children with pervasive developmental disorders.
WISC–III (Wechsler, 1991) index score profiles and their characteristics were examined with traditional statistics in a large Swedish sample consisting of children with autistic disorder (n = 85), Asperger's disorder (n = 341), or pervasive developmental disorders not otherwise specified (PDD-NOS; n = 94). There was a clear and significant difference in level between children with Asperger's disorder, who performed in the average range according to the Swedish standardization, and children with either autistic disorder or PDD-NOS, who performed below the average range (almost 2 standard deviations below the mean), but few other differences between the diagnostic groups were found. The variation in this sample, compared with the Swedish standardization, was generally larger in regard to the size of standard deviations and to the proportion of individuals who exhibited significant differences between indices. The result implied that a WISC–III profile could not be used to discriminate between the different PDDs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Development and psychometric evaluation of the Yale–Brown Obsessive-Compulsive Scale—Second Edition.
The Yale–Brown Obsessive-Compulsive Scale (Y-BOCS; Goodman, Price, Rasmussen, Mazure, Delgado, et al., 1989) is acknowledged as the gold standard measure of obsessive-compulsive disorder (OCD) symptom severity. A number of areas where the Y-BOCS may benefit from revision have emerged in past psychometric studies of the Severity Scale and Symptom Checklist. Therefore, we created the Yale–Brown Obsessive-Compulsive Scale—Second Edition (Y-BOCS–II) by revising the Severity Scale item content and scoring framework, integrating avoidance into the scoring of Severity Scale items, and modifying the Symptom Checklist content and format. One hundred thirty treatment-seeking adults with OCD completed a battery of measures assessing OCD symptom severity and typology and depressive and anxious symptomology. Interrater and test–retest reliability were assessed on a subsample of participants. The Y-BOCS–II showed strong internal consistency for the Symptom Checklist (Kuder–Richardson-20 = .91) and Severity Scale (α = .89). Test–retest and interrater reliabilities were both high (intraclass correlations > .85). Confirmatory factor analyses did not show adequate fit with previous models of the Y-BOCS. Exploratory factor analysis revealed a two-factor solution generally consistent with the Obsession and Compulsion Severity subscales. Construct validity was supported by strong correlations with clinician-rated measures of OCD symptom severity and moderate correlations with measures of worry and depressive symptoms. Taken together, the Y-BOCS–II has excellent psychometric properties in assessing the presence and severity of obsessive-compulsive symptoms. Although the Y-BOCS remains a reliable and valid measure, the Y-BOCS–II may provide an alternative method of assessing symptom presence and severity.

Understanding the heterogeneity of BPD symptoms through latent class analysis: Initial results and clinical correlates among inner-city substance users.
The current study investigated the heterogeneity of borderline personality disorder (BPD) symptoms in a sample of 382 inner-city, predominantly African American male substance users through the use of latent class analysis. A 4-class model was statistically preferred, with 1 class interpreted to be a baseline class, 1 class interpreted to be a high-BPD class, and 2 classes interpreted as intermediate classes. As a secondary goal, we examined the resulting BPD classes with respect to relevant clinical correlates, including temperamental vulnerabilities (affective instability, impulsivity, and interpersonal instability), childhood emotional abuse, drug choice, and co-occurring mood and anxiety disorders. The high-BPD class evidenced the highest levels of the temperamental vulnerabilities and environmental stressors, the baseline class evidenced the lowest levels, and the 2 intermediate classes fell in between. In addition, the high-BPD class had a higher probability of cocaine and alcohol dependence, as well as mood and anxiety disorders, than did the baseline class. Rates of alcohol use and mood disorders for the intermediate classes fell in between the high-BPD and the baseline classes. Results are discussed in relation to the current diagnostic conceptualization of BPD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Contemporary militant extremism: A linguistic approach to scale development.
In this article, the authors describe procedures used in the development of a new scale of militant extremist mindset. A 2-step approach consisted of (a) linguistic analysis of the texts produced by known terrorist organizations and selection of statements from these texts that reflect the mindset of those belonging to these organizations and (b) analyses of the structural properties of the scales based on 132 selected statements. Factor analysis of militant extremist statements with participants (N = 452) from Australia, Serbia, and the United States produced 3 dimensions: (a) justification and advocacy of violence (War factor), (b) violence in the name of God (God factor), and (c) blaming Western nations for the problems in the world today (West factor). We also report the distributions of scores for the 3 subscales, mean differences among the 3 national samples, and correlations with a measure of dogmatism (M. Rokeach, 1956).

Description and psychometric evaluation of the Youth Counseling Impact Scale.
The present article describes and evaluates the Youth Counseling Impact Scale (YCIS; L. Bickman et al., 2007), a recently developed therapeutic process measure that assesses youths' perceptions of the impact individual mental health counseling sessions have on their thoughts, feelings, and behaviors. This measure is intended for frequent use in the mental health treatment of youths aged 11–18. It provides a general Impact score as well as two subscale scores: Insight and Change. Five hundred youths receiving mental health services participated in this investigation. Classical test theory, item response theory, confirmatory factor nalysis, and analyses of the relationship of the YCIS with other scales were used to evaluate the research questions. The results suggest that, overall, the YCIS is a well-functioning scale with good psychometric properties. The proposed model for 1 primary general factor of impact and 2 secondary factors (Insight and Change) fit the data well. Specific weaknesses of the scale are discussed, and possible improvements are suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Factor structure of the acute stress disorder scale in a sample of Hurricane Katrina evacuees.
Acute stress disorder (ASD) is a poorly understood and controversial diagnosis (A. G. Harvey & R. A. Bryant, 2002). The present study used confirmatory factor analysis (CFA) to test the factor structure of the most widely used self-report measure of ASD, the Acute Stress Disorder Scale (R. A. Bryant, M. L. Moulds, & R. M. Guthrie, 2000), in a sample of Hurricane Katrina evacuees relocated to a Red Cross emergency shelter in Austin, Texas. Results indicated that the proposed 4-factor structure did not fit the data well. However, an alternate 2-factor model did fit the data well. This model included a second-order Distress factor (onto which the Reexperiencing, Arousal, and Avoidance factors loaded strongly) that was positively correlated with the Dissociation factor. Implications for the ASD construct and its measurement are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Development and psychometric evaluation of the Index of Dental Anxiety and Fear (IDAF-4C+).
The measurement of dental fear is important due to its high prevalence and appreciable individual, clinical, and public health consequences. However, existing measures of dental anxiety and fear (DAF) have theoretical or practical limitations. This study describes the development and subsequent assessment of the reliability and validity of test scores of a new DAF scale for adults. The Index of Dental Anxiety and Fear (IDAF-4C+) contains 3 modules that measure DAF, dental phobia, and feared dental stimuli. The final 8-item DAF module (IDAF-4C) assesses emotional, behavioral, physiological, and cognitive components of the anxiety and fear response. The proposed scale dimensionality received support from exploratory factor analysis. IDAF-4C items showed good internal consistency (Cronbach's α = .94) and test–retest reliability at 4 months (r = .82), and the scale was strongly associated with other dental fear scales as well as with dental visiting patterns, avoidance of the dentist, and dental phobia diagnosis. The convergent and predictive validity of the IDAF-4C compared positively to Corah's (1969; Corah, Gale, & Illig, 1978) Dental Anxiety Scale and a single-item measure of dental fear, and the scale predicted future dental visiting and visit perceptions. Both phobia and stimulus modules showed strong and statistically significant associations with DAF ratings. In all, sufficient evidence is provided to demonstrate that the new scale would be a useful tool to assess DAF in an adult population. The IDAF-4C+ is based on strong theoretical underpinnings, yet the scale is practical enough for application across a variety of potential uses.

Perceived threat and perceived neglect: Couples' underlying concerns during conflict.
The Couples Underlying Concern Inventory assesses 2 fundamental types of distress that couples experience during interpersonal conflict. Perceived threat involves a perception that one's partner is blaming and controlling the self. Perceived neglect involves a perception that one's partner is failing to make desired contributions or investments. Scales measuring these 2 underlying concerns were developed in Study 1, where a sample of 1,224 married people rated a pool of 57 words describing oneself and perceptions of a partner during a specific episode of conflict. Factor analysis identified 2 dimensions, and 2 brief 8-item scales were created. In Study 2, a sample of 2,315 married people completed the resulting 16-item inventory along with 10 self-report scales measuring types of emotion, cognition, and behavior during conflict. A 2-dimensional factor structure was confirmed, and measurement invariance was demonstrated across 4 racial/ethnic groups. Both perceived threat and perceived neglect correlated with relationship satisfaction and conflict communication. More importantly, each concern was associated with a different, and theoretically expected, set of variables regarding self emotion, emotion perceived in a partner, and cognition during conflict.

Differences in offending patterns between adolescent sex offenders high or low in callous—unemotional traits.
In the present study, the authors investigated whether callous and unemotional (CU) traits designated a distinct and important group of adolescent sex offender. A sample of 150 detained adolescents (mean age = 15.89, SD = 1.53) with a current sexual offense disposition was assessed with a self-report measure of CU traits and through extensive assessments of the characteristics of their sexual offending behaviors using self-report interviews and file review. Results indicated that after controlling for the severity of their history of impulsive/antisocial behaviors, offenders high on CU traits had a greater number of sexual offense victims, used more violence with their victims, and engaged in more sexual offense planning than those low on these traits. The 2 groups did not differ greatly on the age of, gender of, or relationship with their victims. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
The measurement of executive function at age 3 years: Psychometric properties and criterion validity of a new battery of tasks.
In this study, the authors examined the psychometric properties and criterion validity of a newly developed battery of tasks that were designed to assess executive function (EF) abilities in early childhood. The battery was included in the 36-month assessment of the Family Life Project (FLP), a prospective longitudinal study of 1,292 children oversampled from low-income and African American families. Ninety-one percent of children were able to complete 1 or more of the tasks. Psychometric analyses were used to test the dimensionality of each task, evaluate the item and task properties, test the dimensionality of the task battery, and evaluate the criterion validity of the battery with multi-informant measures of attention-deficit/hyperactivity disorder (ADHD) symptomatology and child performance on two subtests of the Wechsler Preschool and Primary Scale of Intelligence. Results indicated that the tasks were successful in measuring interindividual differences in child EF ability, that task scores were most informative about ability level for children in the low to moderate range of ability, that children's performance across the entire battery was adequately summarized by a single factor, and that individual differences on the EF battery were related to ADHD symptomatology and intelligence in expected ways. Results are discussed with respect to the importance of developing psychometrically sound, scalable instruments that facilitate the measurement of interindividual differences in intraindividual change of EF across the early childhood period.

Validation of a mental health assessment in an African conflict population.
We studied the validity of the assessment of posttraumatic stress disorder (PTSD) and depression within the context of an epidemiological mental health survey among war-affected adolescents and young adults in northern Uganda. Local language versions of the Posttraumatic Diagnostic Scale (PDS) and the Depression section of the Hopkins Symptom Checklist (DHSCL) were administered by trained local interviewers. Correlations with probable predictor variables (i.e., trauma exposure), outcomes (e.g., impaired functioning), and local idioms of distress (i.e., spirit possession) were determined to estimate criterion-related construct validity. To assess convergent validity, expert clinicians reinterviewed a subsample using structured interviews (the Clinician Administered PTSD Scale [CAPS] and the Mini International Neuropsychiatric Interview [MINI]). Depression and PTSD symptoms as assessed by the local interviewers correlated with the context variables as predicted. After optimizing the scoring algorithm, we found good agreement between the PDS-based diagnoses and expert diagnoses. However, the concordance for depression diagnoses was not satisfactory. Results show that mental health assessments in African languages can produce reliable and valid data but that caution is warranted in the unevaluated transfer of cutoff scores and scoring algorithms.

Detection of feigned ADHD in college students.
Significant motivations and incentives exist for young-adult students to seek a diagnosis of attention-deficit/hyperactivity disorder (ADHD). With ADHD information readily accessible on the Internet, today's students are likely to be symptom educated prior to evaluation. This may result in false-positive diagnoses, particularly when students are motivated to convey symptoms. We evaluated the utility of ADHD symptom checklists, neurocognitive tests, and measures initially developed to detect feigned neurocognitive or psychiatric dysfunction (symptom validity tests [SVTs]). The performance of 31 undergraduates financially motivated and coached about ADHD via Internet-derived information was compared to that of 29 ADHD undergraduates following medication washout and 14 students not endorsing symptomatology. Results indicated malingerers readily produced ADHD-consistent profiles. Symptom checklists, including the ADHD Rating Scale and Conners's Adult ADHD Rating Scale–Self-Rating Form: Long, were particularly susceptible to faking. Conners's Continuous Performance Test—II findings appeared more related to motivation than condition. Promising results were seen with all cognitive SVTs (Test of Memory Malingering [TOMM], Digit Memory Test, Letter Memory Test, and Nonverbal–Medical Symptom Validity Test), particularly TOMM Trial 1 when scored using Trial 2 criteria. All SVTs demonstrated very high specificity for the ADHD condition and moderate sensitivity to faking, which translated into high positive predictive values at rising base rates of feigning. Combining 2 or more failures resulted in only modest declines in sensitivity but robust specificity. Results point to the need for a thorough evaluation of history, cognitive and emotional functioning, and the consideration of exaggerated symptomatology in the diagnosis of ADHD.

Validity of Rorschach Inkblot scores for discriminating psychopaths from nonpsychopaths in forensic populations: A meta-analysis.
Gacono and Meloy (2009) have concluded that the Rorschach Inkblot Test is a sensitive instrument with which to discriminate psychopaths from nonpsychopaths. We examined the association of psychopathy with 37 Rorschach variables in a meta-analytic review of 173 validity coefficients derived from 22 studies comprising 780 forensic participants. All studies included the Hare Psychopathy Checklist or one of its versions (Hare, 1980, 1991, 2003) and Exner's (2003) Comprehensive System for the Rorschach. Mean validity coefficients of Rorschach variables in the meta-analysis ranged from −.113 to .239, with a median validity of .070 and a mean validity of .062. Psychopathy displayed a significant and medium-sized association with the number of Aggressive Potential responses (weighted mean validity coefficient = .232) and small but significant associations with the Sum of Texture responses, Cooperative Movement = 0, the number of Personal responses, and the Egocentricity Index (weighted mean validity coefficients = .097 to .159). The remaining 32 Rorschach variables were not significantly related to psychopathy. The present findings contradict the view that the Rorschach is a clinically sensitive instrument for discriminating psychopaths from nonpsychopaths.

The bilevel structure of the Outcome Questionnaire–45.
The structure of the Outcome Questionnaire–45 (Lambert et al., 2001) was examined in a sample of 1,100 university counseling center clients using confirmatory factor analysis. Specifically, the relative fit of 1-factor, 3-factor orthogonal, 3-factor oblique, 4-factor hierarchical, and 4-factor bilevel models were examined. Although the 3-factor oblique, 4-factor hierarchical, and 4-factor bilevel models fit the data well, the 4-factor bilevel model fit the data best. The results provided support for the fit of the 4-factor bilevel model where each item loads on 1 of the 3 independent scales of Symptom Distress, Social Role Performance, and Interpersonal Relations, in addition to a nonoverlapping general distress factor.

Psychometric properties and U.S. National norms of the Evidence-Based Practice Attitude Scale (EBPAS).
The Evidence-Based Practice Attitude Scale (EBPAS) assesses mental health and social service provider attitudes toward adopting evidence-based practices. Scores on the EBPAS derive from 4 subscales (i.e., Appeal, Requirements, Openness, and Divergence) as well as the total scale, and preliminary studies have linked EBPAS scores to clinic structure and policies, organizational culture and climate, and first-level leadership. EBPAS scores are also related to service provider characteristics, including age, education level, and level of professional development. The present study examined the factor structure, reliability, and norms of EBPAS scores in a sample of 1,089 mental health service providers from a nationwide sample drawn from 100 service institutions in 26 states in the United States. The study also examined associations of provider demographic characteristics with EBPAS subscale and total scores. Confirmatory factor analysis supported a second-order factor model, and reliability coefficients for the subscales ranged from .91 to .67 (total scale = .74). The study establishes national norms for the EBPAS so that comparisons can be drawn for U.S. local as well as international studies of attitudes toward evidence-based practices. The results suggest that the factor structure and reliability are likely generalizable to a variety of service provider contexts and different service settings and that the EBPAS subscales are associated with provider characteristics. Directions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Longitudinal tests of competing factor structures for the Rosenberg Self-Esteem Scale: Traits, ephemeral artifacts, and stable response styles.
Self-esteem, typically measured by the Rosenberg Self-Esteem Scale (RSE), is one of the most widely studied constructs in psychology. Nevertheless, there is broad agreement that a simple unidimensional factor model, consistent with the original design and typical application in applied research, does not provide an adequate explanation of RSE responses. However, there is no clear agreement about what alternative model is most appropriate—or even a clear rationale for how to test competing interpretations. Three alternative interpretations exist: (a) 2 substantively important trait factors (positive and negative self-esteem), (b) 1 trait factor and ephemeral method artifacts associated with positively or negatively worded items, or (c) 1 trait factor and stable response-style method factors associated with item wording. We have posited 8 alternative models and structural equation model tests based on longitudinal data (4 waves of data across 8 years with a large, representative sample of adolescents). Longitudinal models provide no support for the unidimensional model, undermine support for the 2-factor model, and clearly refute claims that wording effects are ephemeral, but they provide good support for models positing 1 substantive (self-esteem) factor and response-style method factors that are stable over time. This longitudinal methodological approach has not only resolved these long-standing issues in self-esteem research but also has broad applicability to most psychological assessments based on self-reports with a mix of positively and negatively worded items.

Multidimensional assessment of criminal recidivism: Problems, pitfalls, and proposed solutions.
All states have statutes in place to civilly commit individuals at high risk for violence. The authors address difficulties in assessing such risk but use as an example the task of predicting sexual violence recidivism; the principles espoused here generalize to predicting all violence. As part of the commitment process, mental health professionals, who are often psychologists, evaluate an individual's risk of sexual recidivism. It is common for professionals conducting these risk assessments to use several actuarial risk prediction instruments (i.e., psychological tests). These tests rarely demonstrate close agreement in the risk figures they provide. Serious epistemological and psychometric problems in the multivariate assessment of recidivism risk are pointed out. Sound psychometric, or in some cases heuristic, solutions to these problems are proffered, in the hope of improving clinical practice. The authors focus on how to make these tests' outputs commensurable and discuss various ways to combine them in coherent, justifiable fashions.

The intolerance of uncertainty index: Replication and extension with an English sample.
Intolerance of uncertainty (IU) is related to anxiety, depression, worry, and anxiety sensitivity. Precedent IU measures were criticized for psychometric instability and redundancy; alternative measures include the novel 45-item measure (Intolerance of Uncertainty Index; IUI). The IUI was developed in French with 2 parts, assessing general unacceptability of uncertainty (15 items, Part A) and manifestations of uncertainty approximating more common anxiety disorder symptoms (30 items, Part B). The psychometric stability of the back-translated English items of the IUI as well as the incremental variance of Parts A and B remain to be assessed. The current study involved 2 samples of English-speaking community participants (n = 437 and n = 309; 73% women and 27% men) who completed the IUI and several related measures. Exploratory and confirmatory factor analyses suggested a refinement of IUI items as well as a unitary structure for Part A and a 3-factor structure for Part B. Regression results suggested Parts A and B each provide incremental validity in measures of worry, generalized anxiety disorder symptoms, negative problem orientation, and depression. Comprehensive results, implications, and future research directions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
Assessment of relationship-specific incentive and threat sensitivities: Predicting satisfaction and affect in adult intimate relationships.
Self-report scales assessing relationship-specific incentive and threat sensitivity were created. Initial tests of factor structure and associations with relationship quality were conducted in a sample of persons in intimate relationships (Study 1). Associations with conceptually related measures were examined to determine convergent and discriminant validity in a sample of dating couples (Study 2). Cross-validation of the factor structure was established in engaged couples (Study 3) and in newlywed couples (Study 4). In Study 4, couples also engaged in a laboratory-based threat task (discussion about a significant marital problem) and incentive task (discussion about loving aspects of the partner/marriage). Relationship incentive sensitivity predicted higher positive affect after the incentive task for both husbands and wives. Relationship threat sensitivity predicted greater anxiety in response to the threat laboratory task for wives only. Implications of approach and avoidance motivations in close relationship processes and outcomes are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
The dirty dozen: A concise measure of the dark triad.
There has been an exponential increase of interest in the dark side of human nature during the last decade. To better understand this dark side, the authors developed and validated a concise, 12-item measure of the Dark Triad: narcissism, psychopathy, Machiavellianism. In 4 studies involving 1,085 participants, they examined its structural reliability, convergent and discriminant validity (Studies 1, 2, and 4), and test–retest reliability (Study 3). Their measure retained the flexibility needed to measure these 3 independent-yet-related constructs while improving its efficiency by reducing its item count by 87% (from 91 to 12 items). The measure retained its core of disagreeableness, short-term mating, and aggressiveness. They call this measure the Dirty Dozen, but it cleanly measures the Dark Triad.

Is criminal behavior a central component of psychopathy? Conceptual directions for resolving the debate.
The development of the Psychopathy Checklist—Revised (PCL–R; R. D. Hare, 2003) has fueled intense clinical interest in the construct of psychopathy. Unfortunately, a side effect of this interest has been conceptual confusion and, in particular, the conflating of measures with constructs. Indeed, the field is in danger of equating the PCL–R with the theoretical construct of psychopathy. A key point in the debate is whether criminal behavior is a central component, or mere downstream correlate, of psychopathy. In this article, the authors present conceptual directions for resolving this debate. First, factor analysis of PCL–R items in a theoretical vacuum cannot reveal the essence of psychopathy. Second, a myth about the PCL–R and its relation to violence must be examined to avoid the view that psychopathy is merely a violent variant of antisocial personality disorder. Third, a formal, iterative process between theory development and empirical validation must be adopted. Fundamentally, constructs and measures must be recognized as separate entities, and neither reified. Applying such principles to the current state of the field, the authors believe the evidence favors viewing criminal behavior as a correlate, not a component, of psychopathy.

The role of antisociality in the psychopathy construct: Comment on Skeem and Cooke (2010).
J. Skeem and D. J. Cooke (2010) asserted that Hare and Neumann consider criminality to be an essential component of the psychopathy construct. The assertion, presented in the guise of a debate on the nature of psychopathy, is neither accurate nor consistent with the clinical and empirical literature on psychopathy to which Hare and Neumann have contributed. Broadly defined antisociality, not criminality per se, is considered to be part of the psychopathy construct. Skeem and Cooke also expressed concerns that the popularity of the Psychopathy Checklist—Revised (R. D. Hare, 2003) inhibits the development and use of other instruments, that it has become the construct it measures, that it deviates from its clinical roots, and that it conflates criminality with personality. These and related issues are addressed, and it is suggested that the arguments proffered by Skeem and Cooke are not convincing, nor do they provide clear directions for theory and research.

One measure does not a construct make: Directions toward reinvigorating psychopathy research—reply to Hare and Neumann (2010).
In our article by J. L. Skeem & D. J. Cooke, (2010), we outlined the dangers inherent in conflating the Psychopathy Checklist—Revised (PCL–R; R. Hare, 1991) with psychopathy itself. In their response, R. Hare and C. Neumann (2010) seemed to agree with key points that the PCL–R should not be confused with psychopathy and that criminal behavior is not central to psychopathy; at the same time, they said we provided no clear directions for theory or research. In this rejoinder, we clarify our argument that progress in understanding the unobservable construct of psychopathy hinges upon setting aside procrustean dependence on a monofocal PCL–R lens to test (a) actual theories of psychopathy against articulated validation hierarchies and (b) the relation between psychopathy and crime. In specifying these conceptual and applied directions, we hope to promote constructive dialogue, further insights, and a new generation of research that better distinguishes between personality deviation and social deviance.

On the viability of PTSD Checklist (PCL) short form use: Analyses from Mississippi Gulf Coast Hurricane Katrina survivors.
One measure commonly used to assess posttraumatic stress disorder is the PTSD Checklist (PCL). Lang and Stein (2005) extracted 4 subsets of PCL items, validating 2 of them for possible use in screening in primary care settings. The viability of the 4 item subsets was evaluated psychometrically in the present study with a sample of Hurricane Katrina survivors (N = 337). Corrected item–total and corrected item–cluster correlations were calculated and compared with those obtained by Lang and Stein. In addition, the sensitivity, specificity, and overall correct classification of the 4 item subsets were evaluated. With methodology approximating Lang and Stein's work, the current data would lead to the development of different screening versions of the PCL. Although some psychometric support was achieved (e.g., high sensitivity), use of the Lang and Stein PCL item subsets for screening natural disaster survivors appears unjustified on the basis of the present data.

Validity of the WISC–IV Spanish for a clinically referred sample of Hispanic children.
The Wechsler Intelligence Scale for Children (WISC) is the most commonly used intelligence test for children. Five years ago, a Spanish version of the WISC–IV was published (WISC-IV Spanish; Wechsler, 2005), but a limited amount of published information is available regarding its utility when assessing clinical samples. The current study included 107 children who were Spanish speaking and of Puerto Rican descent that had been administered the WISC–IV Spanish. They were subdivided into a clinical sample of 35 children with diagnoses of various forms of brain dysfunction (primarily learning disability, attention-deficit/hyperactivity disorder, and epilepsy) and a comparison group made up of 72 normal children who were part of the WISC–IV Spanish version standardization sample. Comparisons between these groups and the standardization sample were performed for the WISC–IV Spanish index and subtest scores. Results indicated that the clinical sample performed worse than the comparison samples on the Working Memory and Processing Speed Indexes, although findings varied to some extent depending on whether the clinical group was compared with the normal comparison group or the standardization sample. These findings provide support for the criterion validity of the WISC–IV Spanish when it is used to assess a clinically referred sample with brain dysfunction.
