The Counseling Center Assessment of Psychological Symptoms Distress Index: A pragmatic exploration of general factors to enhance a multidimensional scale

Objective: The authors attempted to develop and validate a general distress index for a multidimensional psychological symptom/outcome measure used in over 300 college counseling centers with more than 100,000 cases annually: the Counseling Center Assessment of Psychological Symptoms (CCAPS). Method: Four models were compared for fit indices (n = 19,247): the existing first-order factor model (without a general factor), a second-order factor model, a bifactor model, and a single factor or “total score” model. In separate clinical and non-clinical samples, concurrent and divergent validity were examined using several well-established measures of psychological symptoms, as well as two-week test–retest and treatment utilization data. Results: Second-order and bifactor models which captured a single “distress” factor both exhibited good fit to the data relative to the baseline and “total score” model. Validity data indicated that factors adequately measured meaningful clinical onstructs. Conclusion: Both the bifactor and second-order models indicated the presence of a “distress index” comprised items across many of the CCAPS subscales. This distress scale has strong applicability for benchmarking the overall severity and complexity of patients at different centers, and can be used to help identify colleges and universities with areas of clinical strength, which can be studied to improve the field. Clinically, the distress index offers a parsimonious and efficient method for clinicians to monitor patients’ progress through treatment.     

Social influences on smoking in middle-aged and older women

The purpose of this study was to examine the role of 2 types of social influence--general social support and living with a smoker--on smoking behavior among middle-aged and older women in the Women's Health Initiative (WHI) Observational Study. Participants were postmenopausal women who reported smoking at some time in their lives (N=37,027), who were an average age of 63.3 years at baseline. Analyses used multiple logistic regression and controlled for age, educational level, and ethnicity. In cross-sectional analyses, social support was associated with a lower likelihood and living with a smoker was associated with a higher likelihood of being a current smoker and, among smokers, of being a heavier smoker. Moreover, in prospective analyses among baseline smokers, social support predicted a higher likelihood and living with a smoker predicted a lower likelihood of smoking cessation 1-year later. Further, in prospective analyses among former smokers who were not smoking at baseline, social support predicted a lower likelihood and living with a smoker predicted a higher likelihood of smoking relapse 1-year later. Overall, the present results indicate that social influences are important correlates of smoking status, smoking level, smoking cessation, and smoking relapse among middle-aged and older women.     

Modeling general and specific variance in multifaceted constructs: a comparison of the bifactor model to other approaches

This article recommends an alternative method for testing multifaceted constructs. Researchers often have to choose between two problematic approaches for analyzing multifaceted constructs: the total score approach and the individual score approach. Both approaches can result in conceptual ambiguity. The proposed bifactor model assesses simultaneously the general construct shared by the facets and the specific facets, over and above the general construct. We illustrate the bifactor model by examining the construct of Extraversion as measured by the Revised NEO Personality Inventory (NEO‐PI‐R; Costa & McCrae, 1992), with two college samples (N = 383 and 378). The analysis reveals that the facets of the NEO‐PI‐R Extraversion correlate with criteria in opposite directions after partialling out the general construct. The direction of gender differences also varies by facets. Bifactor models combine the advantages but avoid the drawbacks of the 2 existing methods and can lead to greater conceptual clarity.     

The effects of existential threat on reading comprehension of worldview affirming and disconfirming information

Terror management theory posits that cultural worldviews buffer people from thoughts and concerns about death. In support of this claim, numerous studies have shown that mortality salience (MS) increases an individual's motivation to uphold and defend important cultural worldviews. We hypothesized that the motivation to defend cultural worldviews following MS would also enhance people's ability to comprehend worldview affirming (vs. disconfirming) information. Three studies investigated this possibility. Study 1 showed that MS (vs. control) increased reading comprehension of a pro‐evolution essay among participants with a strongly evolutionist worldview, but decreased reading comprehension among participants with a strongly creationist worldview. With the use of a pro‐creation essay, Study 2 conceptually replicated these effects and demonstrated that the interactive effect of worldview and death anxiety on reading comprehension was mediated by defensive motivation. Study 3 replicated the results of Studies 1 and 2 among participants with a strongly evolutionist worldview, but only when the information in the essay was perceived as veridical. Discussion focused on the specific process through which MS affects reading comprehension of worldview relevant ideas. Copyright © 2012 John Wiley & Sons, Ltd.     

Feature-based versus category-based induction with uncertain categories

Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of category-based induction. These results contrast with the observation that people can and do use category-based induction when category membership is known. The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty. Specifically, 2 experiments investigated whether reliance on feature-based inductive strategies is a product of the lack of coherence in the categories used in previous research or is due to the use of a decision-only induction procedure. Experiment 1 found that feature-based reasoning remained the preferred strategy even when categories with relatively high internal coherence were used. Experiment 2 found a shift toward category-based reasoning when participants were trained to classify category members prior to feature induction. Together, these results suggest that an appropriate conceptual representation must be formed through experience with a category before it is likely to be used as a basis for feature induction.     

Toward making progress feedback an effective common factor in couple therapy

Systematic monitoring of individual therapy progress, coupled with feedback to the therapist, reliably enhances therapy outcome by alerting therapists to individual clients who are off track to benefit by the end of therapy. The current paper reviews the possibility of using similar systematic monitoring and feedback of therapy progress as a means to enhance couple therapy outcome, including what measures of therapy progress are most likely to be useful, how to structure feedback to be most useful to therapists, and the likely mediators of the effects of therapy progress feedback. One implicit assumption of therapy progress feedback is that clients unlikely to benefit from therapy can be detected early enough in the course of therapy for corrective action to be taken. As a test of this assumption, midtherapy progress was examined as a predictor of final couple therapy outcome in a sample of 134 distressed couples. Either a brief 7- or 32-item assessment of couple therapy progress at midtherapy detected a substantial proportion (46%) of couples who failed to benefit by the end of therapy. Given that failure to benefit from couple therapy is somewhat predictable across the course of therapy, future research should test whether systematic monitoring and feedback of progress could enhance therapy outcome.     

125 years of perceptual-motor skill research

This article celebrates the contribution that the American Journal of Psychology (AJP) has made to the area of perceptual-motor skill over its 125-year history. We highlight the articles published in AJP and trace the technical and theoretical developments that stem from this groundbreaking work. Included in our overview are AJP articles on the excitability of the motor system, motor learning, adaptation to visual rearrangement, the ecological approach to perception and action, and the measurement of human handedness. We conclude by identifying a number of areas associated with perceptual-motor skill where AJP continues to make an important contribution.     

Schema bias in source monitoring varies with encoding conditions: Support for a probability-matching account

Two experiments examined reliance on schematic knowledge in source monitoring. Based on a probability-matching account of source guessing, a schema bias will only emerge if participants do not have a representation of the source-item contingency in the study list, or if the perceived contingency is consistent with schematic expectations. Thus, the account predicts that encoding conditions that affect contingency detection also affect schema bias. In Experiment 1, the schema bias commonly found when schematic information about the sources is not provided before encoding was diminished by an intentional source-memory instruction. In Experiment 2, the depth of processing of schema-consistent and schema-inconsistent source-item pairings was manipulated. Participants consequently overestimated the occurrence of the pairing type they processed in a deep manner, and their source guessing reflected this biased contingency perception. Results support the probability-matching account of source guessing. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

“I” and the brain

Many philosophers as well as many biological psychologists think that recent experiments in neuropsychology have definitively discredited any notion of freedom of the will. I argue that the arguments mounted against the concept of freedom of the will in the name of natural causal determinism are valuable but not new, and that they leave intact a concept of freedom of the will that is compatible with causal determinism. After explaining this concept, I argue that it is interestingly related to our use of the first person pronoun “I.” I discuss three examples of our use of “I” in thought and language and submit a few questions I would like neuropsychologists to answer concerning the brain processes that might underlie those uses. I suggest answering these questions would support the compatibilist notion of freedom of the will I have offered in part 1.     

The development of causal categorization

Two experiments examined the impact of causal relations between features on categorization in 5- to 6-year-old children and adults. Participants learned artificial categories containing instances with causally related features and noncausal features. They then selected the most likely category member from a series of novel test pairs. Classification patterns and logistic regression were used to diagnose the presence of independent effects of causal coherence, causal status, and relational centrality. Adult classification was driven primarily by coherence when causal links were deterministic (Experiment 1) but showed additional influences of causal status when links were probabilistic (Experiment 2). Children's classification was based primarily on causal coherence in both cases. There was no effect of relational centrality in either age group. These results suggest that the generative model (Rehder, 2003a) provides a good account of causal categorization in children as well as adults.
