An investigation of the relationship between cognitive reactivity and rumination

Teasdale’s (Teasdale, J.D. (1988). Cognitive vulnerability to persistent depression. Cognition and Emotion, 2, 247–274) differential activation hypothesis refers to the ease with which maladaptive cognitive processes are triggered by mild dysphoria as cognitive reactivity. Supporting this model is evidence of a differential association between sad mood and dysfunctional cognitions in formerly depressed and never-depressed individuals and the finding that cognitive reactivity predicts depression recurrence in remitted depressives. The Leiden Index of Depression Sensitivity–Revised (LEIDS-R; Van der Does, A.J.W., Williams, J.M.G. (2003). Leiden Index of Depression Sensitivity–Revised (LEIDS-R). Retrieved September 4, 2007, from http://www.dousa.nl/publications_depression.htm#LEIDS) is a recently developed self-report measure that provides clinicians and researchers with a time-efficient means by which to assess cognitive reactivity. This study investigated the relationship between cognitive reactivity (indexed by the LEIDS-R) and depressive rumination in a nonclinical sample (N = 324). As predicted, partial correlations between the LEIDS-R (subscale and Total scores) and the Ruminative Response Scale (RRS; Nolen-Hoeksema, S., and Morrow, J. (1991). A prospective study of depression and posttraumatic stress symptoms after a natural disaster: The 1989 Loma Prieta earthquake. Journal of Personality and Social Psychology, 61, 115–121) were significant after controlling for current depressive symptoms. A subsample of participants (n= 130) was administered a structured interview to determine current and past depression diagnostic status. Recovered depressed individuals scored more highly on the LEIDS-R Total and LEIDS-R Rumination subscale; however, the groups did not differ on the remaining subscales. Regression analyses indicated that (across all participants) LEIDS-R Total made a unique contribution to the prediction of depression over and above trait level of depressive rumination. Overall, the LEIDS-R is a time-efficient self-report index of cognitive reactivity that demonstrates promise in distinguishing recovered and never-depressed individuals.     

A Relational Approach to Genetic Counseling for Hereditary Breast and Ovarian Cancer

Ethical issues arise for genetic counselors when a client fails to disclose a genetic diagnosis of hereditary disease to family: they must consider the rights of the individual client to privacy and confidentiality as well as the rights of the family to know their genetic risk. Although considerable work has addressed issues of non-disclosure from the client’s perspective, there is a lack of qualitative research into how genetic counselors address this issue in practice. In this study, a qualitative approach was taken to investigate whether genetic counselors in Australia use a relational approach to encourage the disclosure of genetic information from hereditary breast and ovarian cancer (HBOC) clients among family members; and if so, how they use it. Semi-structured qualitative interviews were conducted with 16 genetic counselors from selected states across Australia. Data collection and analysis were guided by a basic iterative approach incorporating a hybrid methodology to thematic analysis. The findings provide indicative evidence of genetic counselors employing a relational approach in three escalating stages––covert, overt and authoritative––to encourage the disclosure of genetic information. The findings lend credence to the notion that genetic counselors envision a form of relational autonomy for their clients in the context of sharing genetic information, and they depart from individualistic conceptions of care/solely client-centered counseling when addressing the needs of other family members to know their genetic status.     

The Mediating Role of Rumination in the Relation Between Quality of Attachment Relations and Depressive Symptoms in Non-Clinical Adolescents

This study examined associations between indices of the quality of attachment relationships of adolescents with parents and peers, rumination, and symptoms of depression. More specifically, a mediation model was investigated in which rumination was hypothesized to mediate the relation between quality of attachment relations and symptoms of depression. A total of 455 high school students completed a battery of questionnaires, including quality of attachment relations, rumination, and depression. Results showed that most indices of quality of attachment relations were significantly associated with rumination and symptoms of depression. When examining the relative contribution of these variables in explaining variance in depression symptoms, trust in parents, communication with peers, and alienation from peers accounted for a significant portion of the variance in depression scores. Finally, the relation between communication with peers and depressive symptoms was fully mediated by rumination, whereas partial mediation was found for the relations between parental trust and depressive symptoms, and between alienation from peers and depressive symptoms. Implications of the findings may be that the treatment of depression in adolescence should consist of both cognitive interventions aimed at targeting ruminative thinking as well as a focus on interpersonal relationships of the adolescent with parents and peers.     

Perceiving musical individuality: performer identification is dependent on performer expertise and expressiveness, but not on listener expertise

Can listeners distinguish unfamiliar performers playing the same piece on the same instrument? Professional performers recorded two expressive and two inexpressive interpretations of a short organ piece. Nonmusicians and musicians listened to these recordings and grouped together excerpts they thought had been played by the same performer. Both musicians and nonmusicians performed significantly above chance. Expressive interpretations were sorted more accurately than inexpressive ones, indicating that musical individuality is communicated more efficiently through expressive performances. Furthermore, individual performers' consistency and distinctiveness with respect to expressive patterns were shown to be excellent predictors of categorisation accuracy. Categorisation accuracy was superior for prize-winning performers compared to non-winners, suggesting a link between performer competence and the communication of musical individuality. Finally, results indicate that temporal information is sufficient to enable performer recognition, a finding that has broader implications for research on the detection of identity cues.     

Integrating mind and body: Graduate psychology education in primary behavioral health care

Extensive research supports the biopsychosocial model, but the current health care system generally operates according to a model of mind-body dualism. Integrated primary behavioral health care offers an alternative to this dualism. This paper describes the University of Louisville Graduate Psychology Education (GPE) program, a pre-doctoral integrated primary behavioral health care training program. This program emphasizes four shared psychosocial determinants that have been associated with physical health status: Victimization and potentially traumatic stress exposure, emotional functioning, social relationship functioning, and illness representations. It does so within the broader context of providing care for individuals who are underserved and economically disadvantaged. The initial phase of the program is evaluated and implications for graduate psychology education and patient care are discussed.     

Neurocognitive function in monozygotic twins discordant for combat exposure: relationship to posttraumatic stress disorder

Neuropsychological deficits have been reported among trauma survivors with posttraumatic stress disorder (PTSD). It is often assumed that these cognitive difficulties are toxic consequences of trauma exposure. Alternatively, they may reflect preexisting characteristics that contribute to the likelihood of developing PTSD. To address this possibility, the authors evaluated cognitive performance in monozygotic twin pairs who were discordant for combat exposure. Pairs were grouped according to whether the combat-exposed brother developed PTSD. The combat-unexposed cotwins of combat veterans with PTSD largely displayed the same performance as their brothers, which was significantly lower than that of non-PTSD combat veterans and their brothers. The results support the notion that specific domains of cognitive function may serve as premorbid risk or protective factors in PTSD.     

Truth and character: sources that older adults can remember

Are age differences in source memory inevitable? The two experiments reported here examined the hypothesis that the type of source information being tested mediates the magnitude of age differences in source memory. In these studies, participants listened to statements made by two different speakers. We compared younger and older adults' source memory in a traditional perceptual source task (memory for voice) and in two affective, conceptually based source tasks (truth of the statements, character of a person in a photo). In both studies, the perceptual and conceptual source information were conveyed in the same manner, as one speaker was associated with one type of information (e.g., female voice speaks truth). Age differences were robust for decisions regarding who said each statement but were negligible or truth or character decisions. These findings are provocative because they suggest that the type of information can influence age-related patterns of performance for source-conveyed information.     

ALDH2 status and conduct disorder mediate the relationship between ethnicity and alcohol dependence in Chinese, Korean, and White American college students

This study examined aldehyde dehydrogense (ALDH2) gene status, alcohol dehydrogense (ADH2) gene status, conduct disorder, and alcohol dependence in Chinese, Korean, and White American college students. Chinese had a lower rate of alcohol dependence (5%) than Koreans (13%) and Whites (17%). Koreans had a higher rate of conduct disorder (15%) than Whites (9%) and Chinese (6%). The relationship of ethnicity to alcohol dependence was mediated by ALDH2 status and conduct disorder, although Chinese ethnicity remained significant. ADH2 status was not related to alcohol dependence with ALDH2 included, and no interactions were significant. Results suggest that different rates of risk (e.g., conduct disorder) and protective (e.g., ALDH2 status) factors partially account for ethnic differences in rates of alcohol dependence.
