Bifactor Modeling and the Estimation of Model-Based Reliability in the WAIS-IV

Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale–Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet been examined for the WAIS-IV is the bifactor model. Bifactor models allow all subtests to load onto both the general factor and their respective index factor directly. Bifactor models are also particularly amenable to the estimation of model-based reliabilities for both global composite scores (ω _h ) and subscale/index scores (ω _s ). Based on the WAIS-IV normative sample correlation matrices, a bifactor model that did not include any index factor cross loadings or correlated residuals was found to be better fitting than the conventional higher order and oblique factor models. Although the ω _h estimate associated with the full scale intelligence quotient (FSIQ) scores was respectably high (.86), the ω _s estimates associated with the WAIS-IV index scores were very low (.13 to .47). The results are interpreted in the context of the benefits of a bifactor modeling approach. Additionally, in light of the very low levels of unique internal consistency reliabilities associated with the index scores, it is contended that clinical index score interpretations are probably not justifiable.     

Gender differences in type a behavior and hostility within an organizational setting

Abstract

Recent investigations suggest that the hostility component of the Type A behavior patter (TABP) is a greater detriment to health than the overall pattern. Some researchers suggest that certain Type A characteristics (e.g., job-involvement) are actually adaptive. This study compared the relative relationship of the TABP and hostility to career-related achievement and psychosocial adjustment among 223 service-delivery employees. Male and female participants completed the Jenkins Activity Survey and the MMPI Hostility Scale as part of a cardiovascular disease risk factor screening. The TABP was positively associated with managerial status for both men and women. However, the TABP was positively related to psychosocial adjustment variables among men only. Hostility was significantly related to undesirable outcomes including lower job status, life dissatisfaction, and unfavorable perceptions of the workplace for both men and women. Discussion addresses organizational factors which might perpetuate hostility and the TABP, as well as gender differences in the experience of these constructs.     

Training Addiction Counselors to Implement an Evidence-Based Intervention: Strategies for Increasing Organizational and Provider Acceptance

One barrier to widespread public access to empirically supported treatments (ESTs) is the limited availability and high cost of professionals trained to deliver them. Our earlier work from 2 clinical trials demonstrated that front-line addiction counselors could be trained to deliver a manualized, group-based cognitive behavioral therapy (GCBT) for depression, a prototypic example of an EST, with a high level of adherence and competence. This follow-up article provides specific recommendations for the selection and initial training of counselors, and for the structure and process of their ongoing clinical supervision. We highlight unique challenges in working with counselors unaccustomed to traditional clinical supervision. The recommendations are based on comprehensive feedback derived from clinician notes taken throughout the clinical trials, a focus group with counselors conducted 1 year following implementation, and interviews with key organization executives and administrators.     

A China–New Zealand comparison of forgiveness

The present study examined the practice of forgiveness among participants from China (N = 172) and New Zealand (N = 91). We tested a theoretical model describing the relationships between collectivism, individualism, and forgiveness. Participants from China were more collectivistic and less individualistic than were participants from New Zealand. Overall, participants from New Zealand were more forgiving than were participants from China. Collectivism was positively related to decisional forgiveness in Chinese participants. Decisional forgiveness independently predicted conciliatory behaviour among participants from China, but this was not the case for participants from New Zealand. Thus, the hypothesized model received qualified support.     

Validity of the Cognitive Representations of Hypertension Scales (CRHTN)1

Leventhal and Diefenbach's (1991) self‐regulatory theory is discussed in explaining the dynamic nature of “how” and “what” people think about hypertension and how this information is different according to severity of hypertension. Using a sample of hypertensive adults who had controlled and uncontrolled blood pressure (BP) status, the factor structure of the Cognitive Representations of Hypertension (CRHTN) scales, an instrument based on self‐regulatory theory of Leventhal & Diefenbach, is examined through exploratory, confirmatory, and multigroup factor analyses. Results indicate that a 5‐factor model is representative of theoretical constructs of disease label or symptoms, consequences, and controllability. The model accurately fits observed data for outpatients with controlled and uncontrolled BP status. Results provide support for an understanding of individuals’ cognitive structuring of disease‐specific attitudes, beliefs, and self‐management skills.     

Now or Later? Attentional Processing and Intertemporal Choice

The tendency to discount future prospects in lieu of smaller immediate outcomes is known as temporal discounting. The current work used eye‐tracking methodology to examine attentional processing to different elements of choice during an intertemporal decision task. Our findings reveal that those who tend to prefer the immediate option demonstrate attentional biases that were predictive of choice. When losses were at stake, selective attention biases also predicted unique variance in self‐report measures of risk taking, impulsivity, and self‐control beyond what was accounted for by a discounting parameter (k), a typical method for summarizing intertemporal choice data. Overall, our findings suggest that eye‐tracking measures of selective attention may allow for a better theoretical understanding of the mechanisms and processes involved in intertemporal choice.

Clicking away at co-rumination: co-rumination correlates across different modalities of communication

Co-rumination is associated with positive friendship quality (thought to buffer against anxiety and depression) but paradoxically higher levels of anxiety and depression. With the increasing use of technology for communication among adults, there is little known about co-rumination effects across different modalities of communication. In the current study, we examined co-rumination through four methods (i.e. in person, phone calls, text messaging, and social media) in two separate samples - college students and participants from the community. Classic co-rumination effects were found for in-person communications, and we found that co-rumination by telephone as well as by texting, for a college student sample only, mirrors some of these findings for in-person co-rumination. In studies of co-rumination, evaluation of multiple modes of communication is warranted.

The Immune System as a Sensory System: Implications for Psychology

The brain and immune system form a bidirectional communication network in which the immune system operates as a sense organ to provide the brain with information about infection and injury, thereby allowing the brain to coordinate a defense. Activated immune cells release proteins called cytokines, which signal the brain by both blood and neural routes. Information that reaches the brain across this sensory channel produces large changes in neural activity, behavior, mood, and cognitive functioning. Appreciation of the functioning of this network may illuminate poorly understood aspects of stress, depression, and intraindividual variability in behavior, mood, and cognition.     

Stressors Experienced During Deployment Among Canadian Armed Forces Personnel: Factor Structure of Two Combat Exposure Scales

Combat exposure is linked to increased mental health problems among military personnel. Reliable, precise, and efficient measurement of combat experiences can facilitate understanding of the effects of combat on mental health. This study examined the psychometric properties of 2 scales used to assess deployment experiences in Canadian Armed Forces (CAF) personnel in 2 different settings: during a Third Location Decompression (TLD) program after deployment, and during routine postdeployment screening. Principal components analyses yielded similar results for the 2 measures. The components containing items relevant to Exposure to the Dead and Injured, Dangerous Environment, and Active Combat were common across both surveys. The TLD results revealed a fourth component, Personal Suffering, while the postdeployment screening data revealed a fourth component, Perceived Responsibility. This study found categories of deployment stressors that can be used for further analysis, and underscores the importance of assessing a broad range of exposures in the combat environment.
