Replacing the Patient: The Fiction of Prosthetics in Medical Practice

The invention of computer simulations used for practicing surgical maneuvers in a video game-like format has an ancestry in the artificial limbs of history and is reflected, grotesquely, in Edgar Allan Poe's short story, "The Man That Was Used Up" (1850). The nineteenth century worked to ensure that the incomplete body did indeed retain a sense of self by creating prostheses to mimic corporeal wholeness. Our present-day technology seems intent on doing precisely the opposite, deliberately fragmenting the body and challenging our understanding of the body and the prosthetic.     

Convergence and predictive validity in measures of optimism and pessimism: Sequential studies

Optimism and pessimism are personality variables that have repeatedly been shown to affect health, job performance, and social relationships. Various instruments purport to measure these dispositions that differ substantially in their theoretical and measurement models. While research has examined relations between subsets of these measures, their unique predictive ability has been neglected. Three sequential studies evaluated the interrelation and predictive ability of the three most utilized instruments, the Life Orientation Test (LOT), the O/P Instrument (OPI) and variants of the Attributional Style Questionnaire (ASQ). Consistent with expectations, measures sharing a future-expectancy component (LOT and OPI) were moderately related and most predictive of health, depression, and coping. ASQ measures were modestly related to the LOT and OPI and offered less consistent predictions.     

Disseminating a smokeless tobacco cessation intervention model to dental hygienists: a randomized comparison of personalized instruction and self-study methods.

This study evaluated 2 methods of disseminating an empirically validated smokeless tobacco intervention delivered during routine dental care. Twenty cities within 12 states were stratified and then randomized to 1 of 3 groups: personalized instruction (PI), self-study (SS), or delayed training (DT) control. Dental hygienists in the SS condition were sent a manual and video. Those in the PI condition were recruited to attend a workshop. Thirty-seven percent of eligible hygienists agreed to participate. At 12 months postenrollment, hygienists in the SS and PI conditions significantly increased their "Assist" behaviors (discuss cessation techniques, help patient set a quit date, and provide cessation materials) and reported fewer perceived barriers to delivering the intervention as compared with hygienists in DT. An economic analysis suggests that SS is more cost-effective than PI.     

Addressing multiple relationships between clients and therapists in lesbian, gay, bisexual, transgender communities

Therapists working in lesbian, gay, bisexual, and transgender (LGBT) communities are likely to experience the potential to engage in multiple relationships with their clients. Currently, the American Psychological Association's (2002) ethics code and the related literature base offer minimal direct guidance to therapists practicing in LGBT communities. In this article, the authors review current literature regarding multiple relationships in psychotherapy, considering how this literature addresses issues specific to practitioners working within LGBT communities, present a case study highlighting the negotiation of a multiple relationship between a client and therapist who both identify as lesbian, and offer recommendations for practitioners working within LGBT communities.     

Divergent trajectories in the aging mind: changes in working memory for affective versus visual information with age

Working memory mediates the short-term maintenance of information. Virtually all empirical research on working memory involves investigations of working memory for verbal and visual information. Whereas aging is typically associated with a deficit in working memory for these types of information, recent findings suggestive of relatively well-preserved long-term memory for emotional information in older adults raise questions about working memory for emotional material. This study examined age differences in working memory for emotional versus visual information. Findings demonstrate that, despite an age-related deficit for the latter, working memory for emotion was unimpaired. Further, older adults exhibited superior performance on positive relative to negative emotion trials, whereas their younger counterparts exhibited the opposite pattern.     

Psychometric evaluation of the behavioral inhibition/behavioral activation scales in a large sample of outpatients with anxiety and mood disorders

The latent structure, reliability, and validity of the Behavioral Inhibition/Behavioral Activation Scales (BIS/BAS; C. L. Carver and T. L. White, 1994) were examined in a large sample of outpatients (N = 1,825) with anxiety and mood disorders. Four subsamples were used for exploratory and confirmatory factor analyses. In addition to generally upholding a latent structure found previously in nonclinical samples, results indicated measurement invariance of the BIS/BAS between genders and a higher order structure of the BAS scales. Convergent and discriminant validity of the BIS/BAS were supported by findings that the subscales correlated most strongly with measures of neighboring personality constructs (e.g., BIS with neuroticism, BAS with positive affect) than with measures of current anxiety and depression symptoms. Overall, the results support the psychometric properties of the BIS/BAS in this clinical sample.     

On the delay-dependent involvement of the hippocampus in object recognition memory

The role of the hippocampus in object recognition memory processes is unclear in the current literature. Conflicting results have been found in lesion studies of both primates and rodents. Procedural differences between studies, such as retention interval, may explain these discrepancies. In the present study, acute lidocaine administration was used to temporarily inactivate the hippocampus prior to training in the spontaneous object recognition task. Male C57BL/6J mice were administered bilateral lidocaine (4%, 0.5 microl/side) or aCSF (0.5 microl/side) directly into the CA1 region of the dorsal hippocampus 5 min prior to sample object training, and object recognition memory was tested after a short ( 5 min) or long (24 h) retention interval. There was no effect of intra-hippocampal lidocaine on the time needed for mice to accumulate sample object exploration, suggesting that inactivation of the hippocampus did not affect sample session activity or the motivation to explore objects. Lidocaine-treated mice exhibited impaired object recognition memory, measured as reduced novel object preference, after a 24 h but not a 5 min retention interval. These data support a delay-dependent role for the hippocampus in object recognition memory, an effect consistent with the results of hippocampal lesion studies conducted in rats. However, these data are also consistent with the view that the hippocampus is involved in object recognition memory regardless of retention interval, and that object recognition processes of parahippocampal structures (e.g., perirhinal cortex) are sufficient to support object recognition memory over short retention intervals.     

Effectiveness Research: Transporting Interpersonal Psychotherapy for Depressed Adolescents (IPT-A) From the Lab to School-Based Health Clinics

This paper describes the process of modifying and transporting an evidence-based treatment, Interpersonal Psychotherapy for Depressed Adolescents (IPT-A), from a university setting to school-based health clinics. It addresses conceptual issues involved in the shift from efficacy to effectiveness research as well as operational issues specific to the transport of IPT-A into school-based health clinics. Consideration is given to the rationale for an IPT-A effectiveness study, methodological concerns, and the timing of the move from the lab to the community. The authors identify challenges and barriers to initiating effectiveness and transportability research and provide suggestions for overcoming these barriers. Recommendations for conducting research in school-based practice settings are provided.
