Latina breast cancer survivors' lived experiences: diagnosis, treatment, and beyond

Latina breast cancer survivors are not benefiting from advances in psychosocial interventions. Despite their greater breast cancer burden, there is a dearth of information about this population. This qualitative study examined the experiences of 18 immigrant Latina breast cancer survivors along the survivorship continuum, from diagnosis to long-term survivorship. The authors conducted separate focus groups with women in the acute, reentry, and long-term survivorship stages. Through grounded theory analysis, the authors uncovered 5 themes of experience: perceptions of psychological well-being, impact of diagnosis, impact of treatment, need for social support, and development of new attitudes. Some themes were applicable across all survivorship stages, whereas others were more salient at a particular stage. Within themes, the authors identified experiences reported in the general literature (i.e., the debilitating effect of chemotherapy) and distinct cultural experiences (i.e., fear that a cancer diagnosis leads to certain death). Results suggest that treatments tailored for each survivorship stage are more likely to be effective than generic interventions. These findings have the potential to lessen health disparities in utilization of psychosocial treatments by Latina breast cancer survivors.     

Detection and validation of unscalable item score patterns using item response theory: an illustration with Harter's Self-Perception Profile for Children

We illustrate the usefulness of person-fit methodology for personality assessment. For this purpose, we use person-fit methods from item response theory. First, we give a nontechnical introduction to existing person-fit statistics. Second, we analyze data from Harter's (1985) Self-Perception Profile for Children (Harter, 1985) in a sample of children ranging from 8 to 12 years of age (N = 611) and argue that for some children, the scale scores should be interpreted with care and caution. Combined information from person-fit indexes and from observation, interviews, and self-concept theory showed that similar score profiles may have a different interpretation. For some children in the sample, item scores did not adequately reflect their trait level. Based on teacher interviews, this was found to be due most likely to a less developed self-concept and/or problems understanding the meaning of the questions. We recommend investigating the scalability of score patterns when using self-report inventories to help the researcher interpret respondents' behavior correctly.     

ARE ALL LATINAS THE SAME? PERCEIVED BREAST CANCER SCREENING BARRIERS AND FACILITATIVE CONDITIONS

In this article, we examine perceived breast cancer screening barriers and facilitative conditions for immigrant women from Mexico, Puerto Rico, Cuba, El Salvador, and South America ( N = 58). Focus groups conducted separately with women of each ancestry were analyzed using grounded theory methods. Identified barriers comprise secrecy, lack of information, embarrassment, fear, and distrust of health care providers. Perceived facilitative conditions include knowing the importance of early detection and noticing a symptom. We compare and contrast findings across ancestries and discuss how psychosocial and cultural factors could be better integrated into early detection programs. The women's high screening rates also suggest that breast cancer screening can be facilitated in this population by addressing institutional factors (e.g., access to health care, transportation).     

Testing discrepancy effects: A critique, a suggestion, and an illustration

To assess the effects of discrepancy between two independent variables, investigators sometimes compute difference scores and correlate such scores with a criterion variable. However, the correlation of the difference with the criterion is accounted for by the correlations of the difference constituents with the criterion and the constituents’ variances. It follows that when investigators are testing a prediction that is not captured by the difference constituents’ main effects, using the difference correlation analysis may be misleading. Under these circumstances, the effects of a discrepancy between two independent variables can be assessed by a test of their interaction. The problems inherent in using difference scores and the advantage of testing the interaction are illustrated in relation to research programs on two separate topics in social psychology.     

Connectionist semantic systematicity

Fodor and Pylyshyn [Fodor, J. A., & Pylyshyn, Z. W. (1988). Connectionism and cognitive architecture: A critical analysis. Cognition, 28, 3–71] argue that connectionist models are not able to display systematicity other than by implementing a classical symbol system. This claim entails that connectionism cannot compete with the classical approach as an alternative architectural framework for human cognition. We present a connectionist model of sentence comprehension that does not implement a symbol system yet behaves systematically. It consists in a recurrent neural network that maps sentences describing situations in a microworld, onto representations of these situations. After being trained on particular sentence–situation pairs, the model can comprehend new sentences, even if these describe new situations. We argue that this systematicity arises robustly and in a psychologically plausible manner because it depends on structure inherent in the world.     

Unveiling phonological universals: A linguist who asks "why" is (inter alia) an experimental psychologist

Evans and Levinson are right to hold theories of language accountable for language diversity, but typological data alone cannot determine the structure of mental phonological grammars. Grammatical universals are nonetheless testable by formal and experimental methods, and the growing research in experimental phonology demonstrates the viability of a comparative experimental evaluation of the UG hypothesis.     

Individuals high in neuroticism are not more reactive to adverse events

Numerous studies have related neuroticism to negative emotional outcomes of adverse life events, including post-traumatic stress disorder (PTSD) symptoms. However, the nature of the relationship between neuroticism and post-trauma symptoms is unclear. The purpose of this study was to prospectively examine whether individuals high in neuroticism, relative to low neuroticism individuals, show a larger increase in symptoms after an adverse event. A sample of infantry troops completed questionnaires before deployment to Iraq (n = 214) and about five months (n = 170; 76%) thereafter. The findings showed that, after controlling for an indicator of trauma severity, (a) higher neuroticism individuals reported more PTSD symptoms, depression symptoms, and somatic problems after negative events, and (b) these relationships disappeared after controlling for pre-trauma symptoms. There were no significant differences between individuals high and low in neuroticism in the increase in symptoms from pre to post-trauma. This suggests that individuals high in neuroticism are not more reactive to adverse events.     

Schizotypy and verbal memory in the adolescent general population

The following study examines the relationship between verbal memory deficits and schizotypal traits measured psychometrically from a non- clinical adolescent population. In this transversal analytical study participated 139 subjects. They were secondary school students, with ages ranging from 13 to 16 years old (mean= 14, 35; Sta.Dev.= 0, 548). After administrating the scales O-LIFE (psychometrical schizotypy), CVLT (verbal memory), and Letters and Numbers subtest of WAIS-III (working memory), data was analyzed utilizing Pearson correlations and mean comparison test. Results showed lack of relations between schizotypy measures and working memory. Nonetheless, some of the O-LIFE dimensions correlated with verbal memory. These findings support partly the literature reviewed. Yet, more work focused on schizotypy and cognitive deficits as risk factors are suggested.
