Predictors of Partner Engagement in PTSD Treatment

A telephone survey was conducted to identify predictors of treatment engagement in 83 cohabitating female partners of 83 Vietnam theater veterans with combat-related post-traumatic stress disorder (PTSD). The survey assessed veterans for their trauma history and PTSD symptoms. Partners were assessed for caregiver burden, patient–partner involvement, PTSD treatment engagement, self-efficacy relating to PTSD, beliefs about benefits of PTSD treatment, and PTSD treatment barriers. Significant predictors of partner PTSD treatment engagement were the couple’s income, patient–partner involvement, and partner caregiver burden. These findings have implications for family interventions that may increase partner PTSD treatment engagement and improve PTSD treatment outcome.     

Aggression and psychopathology in adolescents with a preference for violent electronic games

Associations between a preference for violent electronic games and adolescents’ self‐perceptions of problem behaviors and emotions were examined. It was predicted that a preference for violent games would be associated with negative externalizing characteristics, in particular aggressive emotions and behaviors, on the Youth Self‐Report (YSR), a standardized self‐report measure of adolescent problem behaviors. Thirty‐two 11‐ through 15‐year‐olds (17 girls) listed and categorized favorite electronic games into one of six predetermined categories and completed the YSR. MANOVA revealed significant relationships between a preference for violent games and the Thought Problems subscale (P < .01) and YSR Total Score (P < .05), with trends noted for the Internalizing (P < .06) and Anxious‐Depressed (P < .08) subscales. Expected relationships with externalizing behaviors, including aggression, were not found. However, across all YSR subscales, children with higher preference for violent games had more clinically significant elevations than those with low preference for violent games. On the Total Problems subscale, of the eight children receiving scores in the clinically significant range, six were in the High preference group (three boys and three girls). The failure to find the expected relationships between a preference for violent games and aggressive, externalizing behaviors is puzzling. It is possible that individuals with a preference for violent games may have high exposure to all forms of media violence. Their perceptions of their own behavior, in comparison, may not seem sufficiently aggressive to justify endorsement of problems in this area. Or, playing violent electronic games may promote a disconnection between the emotions normally associated with violence and violent acts. These explanations are consistent with a desensitization model where exposure to media violence decreases sensitivity to aggression. Aggr. Behav. 28:134–144, 2002. © 2002 Wiley‐Liss, Inc.     

Advocacy for Counseling and Counselors: A Professional Imperative

Although advocacy both for clients and for the profession is essential for the future of counseling and counselors, advocacy for the profession has received little systematic attention. A national plan for advocacy is needed, the effectiveness of which depends on achieving consensus concerning professional identity, promoting a positive public image, establishing effective intraprofessional and interprofessional collaboration, and obtaining the participation of each counselor in advocacy activities. Specific professional advocacy skills and techniques are described.     

Assessment of Nicotine Dependence Among Substance Abusing Adolescent Smokers: A Comparison of the DSM-IV Criteria and the Modified Fagerström Tolerance Questionnaire

Nicotine dependence has been found to be a significant factor in adolescent smoking persistence. However, measures of this construct are primarily adult-derived, limiting their utility as bases for characterizing nicotine dependence and formulating youth intervention strategies. This issue is of particular importance among substance abusing youth who have substantially higher rates of cigarette smoking than do adolescents in the general population. The objectives of this preliminary study were to examine the construct validity of the DSM-IV nicotine dependence criteria and the modified Fagerström Tolerance Questionnaire (mFTQ) and to compare the DSM-IV diagnostic criteria for nicotine dependence with the mFTQ in a sample of 67 adolescent smokers in treatment for substance abuse. Results revealed that more participants were classified as nicotine dependent using DSM-IV criteria than by mFTQ scores. Little evidence was found for construct validity of these measures and convergence between the two measures was low. Findings also suggested that the present measures do not capture optimally broad dimensions of adolescent nicotine dependence.     

Dissociating basal forebrain and medial temporal amnesic syndromes: Insights from classical conditioning

In humans, anterograde amnesia can result from damage to the medical temporal (MT) lobes (including hippocampus), as well as to other brain areas such as basal forebrain. Results from animal classical conditioning studies suggest that there may be qualitative differences in the memory impairment following MT vs. basal forebrain damage. Specifically, delay eyeblink conditioning is spared after MT damage in animals and humans, but impaired in animals with basal forebrain damage. Recently, we have likewise shown delay eyeblink conditioning impairment in humans with amnesia following anterior communicating artery (ACoA) aneurysm rupture, which damages the basal forebrain. Another associative learning task, a computer-based concurrent visual discrimination, also appears to be spared in MT amnesia while ACoA amnesics are slower to learn the discriminations. Conversely, animal and computational models suggest that, even though MT amnesics may learn quickly, they may learn qualitatively differently from controls, and these differences may result in impaired transfer when familiar information is presented in novel combinations. Our initial data suggests such a two-phase learning and transfer task may provide a double dissociation between MT amnesics (spared initial learning but impaired transfer) and ACoA amnesics (slow initial learning but spared transfer). Together, these merging data suggest that there are subtle but dissociable differences in the amnesic syndrome following damage to the MT lobes vs. basal forebrain, and that these differences may be most visible in non-declarative tasks such as eyeblink classical conditioning and simple associative learning.     

Mosaic trisomy 20 and mitigation in capital crimes sentencing: A review and case report

Trisomy 20 is a genetic abnormality in which individuals have an extra copy of chromosome 20. Complete trisomy 20 is rare and believed to be incompatible with life. A mosaic form of trisomy 20, in which only some cells or tissues contain the extra chromosome, is a relatively commonly encountered chromosomal abnormality found during prenatal testing, and c. 90% result in a normal phenotype. However, despite the absence of a consistent phenotype, certain findings have been reported across multiple cases of mosaic trisomy 20. These include an array of morphological findings, developmental delays, and learning disabilities. Beyond physical manifestations, a wide range of developmental and learning delays have also been reported. In this work, we provide an overview of the trisomy 20 literature and a case report of a young adult male with mosaic trisomy 20 who committed homicide. His developmental and life history, eventual diagnosis of mosaic trisomy 20, similarities and differences in his condition compared with prior research findings, and potentially new phenotypic findings associated with trisomy 20 that he manifested (childhood visual hallucinations, self‐injury, polydactyly) are presented. Additionally, the potential role of this genetic diagnosis in his neuropsychiatric history and its successful application as a mitigating factor at his capital sentencing trial are described. We did not identify other similar cases during our search of major scientific and legal databases. As a backdrop, the use of genetics in criminal trials is on the rise, and courts are increasingly likely to accept behavioral genetics evidence; therefore, it is crucial that the legal system is well acquainted with the opportunities and limitations of these approaches.     

Menopause Symptoms and Attitudes of African American Women: Closing the Knowledge Gap and Expanding Opportunities for Counseling

Menopause, a normal midlife transition for women, remains poorly understood, especially for minority women. A total of 226 African American midlife women completed the Menopause Symptoms List (J. M. Perz, 1997); Menopause Attitude Scale (C. Bowles, 1986); Attitudes Toward Menopause checklist (B. L. Neugarten, V. Wood, R. J. Kraines, & B. Loomes, 1963); and instruments to elicit information about health status, stressful life events, social support, and demographics. The results reveal strengths as well as areas of concern for African American women in responding to normative midlife changes. Implications for counselors are explored.     

AX+, BX- discrimination learning in the fear-potentiated startle paradigm: possible relevance to inhibitory fear learning in extinction

The neural mechanisms of fear suppression most commonly are studied through the use of extinction, a behavioral procedure in which a feared stimulus (i.e., one previously paired with shock) is nonreinforced repeatedly, leading to a reduction or elimination of the fear response. Although extinction is perhaps the most convenient index of fear inhibition, a great deal of behavioral work suggests that postextinction training conditioned stimuli are both excitatory and inhibitory, making it difficult to determine whether a neural manipulation affects inhibition, excitation, or some combination thereof. For this reason we sought to develop a behavioral procedure that would render a stimulus primarily inhibitory while at the same time avoiding some of the issues raised by the traditional conditioned inhibition paradigm, namely second-order conditioning, external inhibition, and configural learning. Using the fear-potentiated startle paradigm, we adapted an AX+, BX- training procedure in which stimuli A and X were presented simultaneously and paired with shock, and stimuli B and X were presented simultaneously in the absence of shock. In testing, high levels of fear-potentiated startle were seen in the presence of A and AX and much lower levels were seen in the presence of B and AB, as would be predicted if stimulus B were a conditioned inhibitor. We believe this method is a viable alternative to the traditional conditioned inhibition training procedure and will be useful for studying the neural mechanisms of fear inhibition.     

Accessibility of potential referents following categorical anaphors

In 4 experiments, the authors investigated the accessibility of potential antecedents that were either referents or nonreferents of categorical anaphors using several methodologies. In 2 preliminary experiments, using an immediate probe recognition task, the authors replicated previous findings of inhibition for nonreferents following categorical anaphors. In Experiments 1-3, naming times to nonreferent probes were inhibited, but only at a delay and at the end of the sentence. Eye movements were monitored in Experiment 4, and reading times were found to be slower in end-of-sentence regions following the remention of the nonreferent but not on the nonreferent itself. These results suggest that decreases in nonreferent accessibility are due to postanaphoric processes, such as integrating the nonreferent into the discourse structure, and are not due to more immediate changes in activation occurring as part of the resolution process. Further, some inhibition effects may result from the use of probe tasks that require decisions.     

Development of the Multidimensional Acculturative Stress Inventory for adults of Mexican origin

The Multidimensional Acculturative Stress Inventory (MASI), a 36-item stress measure that was developed to assess acculturative stress among persons of Mexican origin living in the United States, was tested on a community sample of 174 adults (117 women, 57 men). Principal-components analyses yielded 4 stable and internally consistent factors: Spanish Competency Pressures (7 items), English Competency Pressures (7 items), Pressure to Acculturate (7 items), and Pressure Against Acculturation (4 items). These 4 factors accounted for 64.4% of the variance and correlated in the expected directions with criterion measures of acculturation and/or psychological adjustment. Further reliability and validity testing of the MASI is discussed as well as the utility of this measure in assessing acculturative stress among adults of Mexican origin.
