Treatment of urethral catheter dependence: A case study of intervention in the interdisciplinary geriatric setting

This case report describes the assessment and treatment of a 69-year-old male medical patient with urethral catheter dependence. Assessment revealed an anxiety/phobic component to the dependence and hypothesized detrusor muscle deconditioning. Retraining of the bladder and desensitization to the anxiety-provoking situation were achieved by exposure to decatheterization in the context of a supportive adult day health care setting. Interdisciplinary collaboration between nursing and psychology were associated with successful functional, social, and psychological outcomes.A psychology intern at the Portland VA Medical Center at the time the study was conducted.     

Use of the MMPI-2 With Chicanos: Strategies for Counselors

The Minnesota Multiphasic Personality Inventory–2 (MMPI-2) is frequently used by professional counselors to assess Chicano or Mexican American clients in various mental health settings. It is important to understand how ethnic and sociocultural variables (e.g., ethnic identity, acculturation, or racism) may influence the assessment process. This article presents strategies for the culturally competent use of the MMPI-2 with this burgeoning Hispanic subpopulation.     

Mishandling the Gift of Life: Noncompliance in Renal Transplant Patients1

Two studies investigating renal transplant patients compliance with their post-transplant medical regimen are presented. Compliance was operationalized as a multidimensional construct incorporating behaviors that represent adherence to the regimen. Study 1 examined the association of noncompliance with clinically significant outcomes and the medical and demographic predictors of noncompliance. Noncompliance was associated with rejection episodes, graft loss, and multiple transplants. The best predictors of noncompliance were medication side effects, age, education, and insurance coverage. Study 2 examined the psychosocial predictors of noncompliance. After age and side-effects complaints, self-efficacy and threat appraisal were the best predictors of compliance. The implications of these results for expectancy-value models of health behaviors (e.g., protection motivation theory; Rogers, 1983) and their ability to predict compliance in patients following long-term regimens are discussed.     

Amnestic effect of intrahippocampal AM251, a CB1-selective blocker, in the inhibitory avoidance, but not in the open field habituation task, in rats

CB1 is the most abundant metabotropic receptor of the brain, being found in areas classically involved in learning and memory and present at higher density at presynaptic terminals. Different sets of evidence support the idea that endogenous ligands (endocannabinoids) to the CB1 receptors act as modulators of neurotransmission. In hippocampus, endocannabinoids seem to act as retrograde messengers mediating down-regulation of GABA release. Previous reports have described a cognitive impairment effect of cannabinoid agonists, or facilitation by antagonists. The scope of the present study is to investigate the effect of intrahippocampal administration of the CB1-selective antagonist, AM251, in two behavioral tasks. One hundred and twelve male Wistar rats with bilateral cannulae implanted in the CA1 region of the dorsal hippocampus were trained in a step-down inhibitory avoidance task (IA, footshock, 0.5 mA) or an open field habituation task (OF). Immediately, after training, animals received an infusion of 0.55, 5.5, and 55.5 ng/side of AM251 (Tocris), or its vehicle (DMSO/saline), via these cannulae. Our results show that AM251 disrupted memory consolidation of the IA task, but not the OF task, an effect that seems to be purely mnemonic since the drug showed no motor performance effects. Only the intermediate dose (5.5 ng/side) of AM251 was effective in IA and the absence of effect with the larger dose may be the consequence of non-specific binding. The fact that OF was not affected raises the possibility that this endogenous system requires some degree of aversiveness to be recruited. We propose that increased levels of endogenous cannabinoids in the hippocampus, following a training session, contribute to facilitate memory consolidation, a process that may have been disrupted with AM251.     

Time-dependent effects of treadmill exercise on aversive memory and cyclooxygenase pathway function

Exercise induces brain function adaptations and improves learning and memory; however the time window of exercise effects has been poorly investigated. Studies demonstrate an important role for cyclooxygenase-2 (COX-2) pathway function in the mechanisms underlying memory formation. The aim of present work was to investigate the effects of treadmill exercise on aversive memory and COX-2, PGE(2) and E-prostanoid receptors contents in the rat hippocampus at different time points after exercise has ended. Adult male Wistar rats were assigned to non-exercised (sedentary) and exercised (running daily for 20min, for 2weeks) groups. The inhibitory avoidance task was used to assess aversive memory and the COX-2, PGE(2) and E-prostanoid receptors (EP1, EP2, EP3 and EP4) levels were determined 1h, 18h, 3days or 7days after the last training session of treadmill exercise. The step down latency in the inhibitory avoidance, COX-2 and EP4 receptors levels were acutely increased by exercise, with a significant positive correlation between aversive memory performance and COX-2 levels. Increased EP2 content decreased PGE(2) levels were observed 7days after the last running session. The treadmill exercise protocol facilitates inhibitory avoidance memory and induces time-dependent changes on COX-2 pathways function (COX-2, PGE(2) and EP receptors).     

Forgiveness aversion: developing a motivational state measure of perceived forgiveness risks

Given the demonstrated psychological, physical, and social benefits of forgiveness, it is striking that there are still strong impediments to its attainment. In this paper, we introduce the multi-dimensional construct of forgiveness aversion, an offense-specific motivational state based on perceived forgiveness risks. The construct and our proposed measure (the Forgiveness Aversion Scale) are composed of three related dimensions: unreadiness, self-protection, and face concerns. Unreadiness refers to the ongoing emotional turmoil that keeps victims from sincerely forgiving. Self-protection refers to the concerns about how offenders will interpret forgiveness. Finally, face concerns reflect victims’ concerns for their reputation. Four studies were completed to develop a state measure of forgiveness aversion through correlation, structural equations modeling, longitudinal analysis, and a hypothetical scenario experiment. Results of four studies reveal differential predictors of the three dimensions of forgiveness aversion and demonstrate that our understanding of the forgiveness process and impediments thereto is enhanced by addressing situation-specific impediments to forgiveness.     

Social Isolation and Perceived Barriers to Establishing Social Networks Among Latina Immigrants

Research has identified numerous mechanisms through which perceived social isolation and lack of social support negatively impact health. Little research attention has been dedicated to factors that influence the development of social networks, which have the potential to decrease perceptions of social isolation and provide social support. There is mixed evidence concerning the availability of supportive social networks for Latinos in the US. This study explores trauma-exposed Latina immigrants’ experiences of social isolation in the US and its perceived causes. Twenty-eight Latina immigrant women participated in an interview about traumatic experiences. Informal help seeking and the availability of friendships in the US were also queried. Frequent comparisons between experiences in their home countries and in the US shaped the emerging themes of social isolation and lack of social support. Women reported feeling lonely, isolated, closed-in, and less free in the US due to family separation and various obstacles to developing and maintaining relationships. Socioeconomic, environmental, and psychosocial barriers were offered as explanations for their limited social networks in the US. Understanding experiences of social isolation as well as barriers to forging social networks can help inform the development of social support interventions that can contribute to improved health among Latinos.     

Identity Shift in Computer-Mediated Environments

The present study uses a public commitment framework to examine how computer-mediated self-presentations can alter identities. Participants were asked to present with one of two traits, extroversion or introversion, in public or private computer-mediated communication. Public presentations were online, whereas private presentations took place in a text document. Only participants that presented themselves publicly internalized the trait presentation, suggesting that identity shift took place. Public self-presentations also contained more certain and definite forms of language than private self-presentations, suggesting that audiences evoke a more committed form of self-presentation. The findings in this research have important implications for the self-construction of identity online, particularly for individuals that use the Internet as a tool for public self-presentation, such as dating sites, social network sites, or blogs. Also, the findings highlight opportunities for theoretical development on identity construction as a function of computer-mediated communication.     

Displays that facilitate performance of multifrequency ratios during motor-respiratory coordination

A large number of ratios between movement and breathing are possible, but only a small number have been performed during exercise. The purpose of this study was twofold: (1) to investigate displays that might facilitate the performance of other ratios; and (2) to test predictions from the sine circle map and continued fractions in a model motor-respiratory task in which participants coordinated arm movement and breathing. Displays consisted of either real-time feedback or a template (non-feedback). The accuracy of ratio performance was significantly greater with the template in which the number and relative positioning of movements and breaths was depicted, compared to with real-time feedback. Across displays, the stability of ratio performance conformed to principles of the sine circle map and was significantly greater for ratios with longer continued fractions. Therefore, the motor-respiratory repertoire can be expanded by increasing participants’ understanding of the pattern to be performed, but performance is constrained by general dynamical principles.
