"AND YOU'RE TELLING ME NOT TO STRESS?" A GROUNDED THEORY STUDY OF POSTPARTUM DEPRESSION SYMPTOMS AMONG LOW-INCOME MOTHERS

Low-income mothers in the U.S. are more likely to experience postpartum depression (PPD) and less likely to seek treatment than their middle-class counterparts. Despite this knowledge, prior research has not provided an in-depth understanding of PPD symptoms as they are experienced by low-income mothers. Through in-depth interviews, this study investigated low-income mothers' ( n  = 19) experiences and explanatory frameworks for their PPD symptoms. Grounded theory analysis uncovered five main categories that linked the participants' PPD symptoms to their lived experiences of mothering in poverty, including: (1) ambivalence, (2) caregiving overload, (3) juggling, (4) mothering alone, and (5) real-life worry. The analysis further located the core experience of PPD for low-income mothers as "feeling overwhelmed" due to mothering in materially and socially stressful conditions. These findings challenge the prevailing biomedical discourse surrounding PPD and situate mothers' symptoms in the context of the material hardships associated with living in poverty.     

Can Personal Values Predict Performance? Evidence in an Academic Setting

In this paper we briefly review the construct of personal values, and we examine whether achievement values may be incrementally related to performance beyond personality. We also consider the motivational processes that may mediate the relationships between characteristics of the individual (personality and values) and performance. In an academic setting, achievement values were related to course performance even after controlling for the relevant personality factors of Conscientiousness, Emotional Stability, and Extraversion. Further, motivational processes of goal content and goal striving mediated the relationships between individual characteristics (personality and values) and performance.     

Orthographic cues to lexical stress: Effects on naming and lexical decision

Words whose spellings represent regular phonemic patterns, such asmint, show advantages in naming and lexical decision tasks over words, such aspint, that have exceptional relations between orthographic and phonemic patterns. We have extended such phenomena to the domain of lexical stress, by showing that disyllabic words whose spellings are consistent with their stress are easier to process than words whose spellings are misleading about stress. Such words are named more quickly and are pronounced with incorrect stress less often (Experiment 1). They are also classified more quickly and accurately in lexical decision tasks (Experiments 2 and 3). These results indicate that literate speakers have learned orthographic correlates to lexical stress in English. In addition, the similarities between results in the phonemic and prosodic domains indicate that models of reading developed for the former could be extended to the latter area.     

Evaluation Study of Lawyers' Satisfaction with Expert Witness Reports

This study attempted to evaluate the satisfaction of personal injury lawyers with expert witness reports from psychologists and psychiatrists. A questionnaire was sent to 514 civil litigation lawyers and 79 (15.4%) were completed. It was found that most lawyers were satisfied with reports and that there was no difference between the standard and quality of expert reports of psychologists and psychiatrists. Criticisms were limited and focussed on the cost, length and lack of clarity of some of the reports. These criticisms are discussed within the context of the reforms within the legal aid system and it is concluded that expert reports are perceived by lawyers as being reasonably good value for money.     

Brain Oxidative Damage Following Acute Immobilization and Mild Emotional Stress

We studied the role of free radicals on brain oxidative damage in rats after acute immobilization stress (restraint) and mild emotional stress (handling). To investigate brain oxidative damage, CuZn and Mn dependent superoxide dismutase (CuZn SOD, Mn SOD) activities, lipid peroxidation (TBARs), Na ⁺ K ⁺ ATPase activity, protein carbonyl (PrC), and reduced and oxidized glutathione (GSH, GSSG) levels were measured in the cerebral cortex (CTX), hippocampus (HIP), and striatum (ST) of the animals after the two different stress stimuli. Because stress produces abnormalities in the hypothalamic-pituitary-adrenal axis, the intensity of the two stress conditions were measured by plasmatic corticosteroid (COR) levels: particularly, COR levels doubled in handled rats and increased 15-fold in restrained animals. The SOD activities increased in CTX and decreased in HIP of the handled rats, while in ST a significant decrease in handled animals but an increase in restrained animals occurred. TBARs, GSH, and GSSG levels remained unchanged, while an index of glutathione redox decreased significantly in ST of handled animals and in CTX of restrained ones. Na ⁺ K ⁺ ATPase activity increased significantly in the HIP and ST of both groups of stressed rats. The stress induced a remarkable increase in PrC levels in all studied cerebral areas. These findings provide evidence to support the idea that stress produces oxidants but that the oxidative damage in stress differs in cerebral areas and could contribute to the degenerative mechanism of aging.
