Why women of lower educational attainment struggle to make healthier food choices: The importance of psychological and social factors

Women of lower educational attainment are more likely to eat unhealthy diets than women of higher educational attainment. To identify influences on the food choices of women with lower educational attainment, 11 focus groups (eight with women of lower, and three with women of higher educational attainment) were held. Using a semi-structured discussion guide, environmental, social, historical and psychological factors known to be associated with food choice were explored. Audio recordings were transcribed verbatim and thematically analysed. Compared to women of higher educational attainment, women of lower educational attainment had less control over their families’ food choices, less support for attempts to eat healthily, fewer opportunities to observe and learn good food-related practices, more negative affect, more perceived environmental constraints and more ambiguous beliefs about the consequences of eating a nutritious diet. These findings provide a starting point for taking forward the design of an intervention to improve the diets of young women.     

Coping,psychological adjustment,and complementary and alternative medicine use in persons living with hiv and aids

Abstract

Many HIV-positive individuals dissatisfied with allopathic approaches to disease management have turned to complementary and alternative medicines (CAM). Although people use CAM for a variety of reasons (e.g., symptom management, holistic approach towards healthcare, improved immunity), the psychological benefits that these treatments may have are still not fully understood. The present study was designed to further previous research that demonstrated relationships between CAM use, stress appraisals, and coping behaviors. HIV-positive individuals (N= 127) completed measures assessing stress appraisals, coping, psychological adjustment, satisfaction with life, and immune functioning. After controlling for ethnicity and sexual orientation, stress appraisals and coping behaviors were found to be related to CAM use. Further, curvilinear relationships between CAM use and adjustment emerged, suggesting that some CAM use may be adaptive. Self-reported immune measures were unrelated to CAM use. In all, it appears that CAM use may be a complex form of coping that assists individuals in adjusting to a life-threatening illness. The implications of these findings with respect to adherence to highly active antiretroviral therapies (HAART) are also discussed.     

Intention versus identification as determinants of adolescents’ health behaviours: evidence and correlates

The present study used a within-participants design to (a) assess the predictive validity of prototype identification versus intention for adolescents’ health behaviours and (b) examine whether control of health behaviour by intention relative to identification is associated with key individual difference variables. Participants were school children (N = 136) who completed measures of intention, perceived behavioural control and prototype identification for 14 health-related behaviours at Time 1, and reported their behaviour 2 weeks later (Time 2). A hierarchical regression showed that prototype identification and intention exhibited similar predictive validity in the prediction of adolescents’ health behaviour. Importantly, identification contributed an additional 6% to the variance in behaviour, after controlling for intention and perceived behavioural control from the theory of planned behaviour [TPB: Ajzen, I. (1991 Ajzen, I. 1991. The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50: 179–211. [Crossref], [Web of Science ®] , [Google Scholar]). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211.]. Additional analyses showed that greater social comparison tendencies, lower agreeableness, greater intellect and less emotional stability were all related to greater control of behaviour by prototype identification. The theoretical and practical implications of these findings are discussed.     

Support during birth interacts with prior trauma and birth intervention to predict postnatal post-traumatic stress symptoms

Background: Many women experience childbirth as traumatic and 2% develop post-traumatic stress disorder. This study examined the role of health practitioner support and personal control during birth as predictors of post-traumatic stress (PTS) symptoms, adjusting for vulnerability factors of prior trauma, depression, control beliefs and birth intervention. It also investigated interactions between support, prior trauma and birth intervention and their association with PTS symptoms.

Methods: A prospective longitudinal survey of 138 women recruited from UK NHS maternity clinics. Measures were taken in pregnancy, 3 weeks and 3 months after the birth.

Results: Support and control during birth were not predictive of postnatal PTS symptoms. However, support was predictive of PTS symptoms in a subset of women with prior trauma (β?=??0.41, R ²?=?16%) at both 3-weeks and 3-months postpartum. The interaction of birth intervention and support was associated with PTS symptoms 3 months after birth, the relationship between support and PTS symptoms was stronger in women experiencing more intervention.

Conclusions: Low support from health practitioners is predictive of postnatal PTS symptoms in women who have a history of trauma. Longer term effects of low support on postnatal PTS symptoms are also found in women who had more intervention during birth.     

Inhibitory Control in Children with Frontal Infarcts Related to Sickle Cell Disease

Evidence from past studies indicates that children with traumatic brain injury experience difficulties with inhibitory control. Less is known about inhibitory control in children with frontal brain injury related to cerebral infarction. We compared the inhibitory performance of children with frontal infarcts related to sickle cell disease with that of a control group of children with sickle cell disease but no history of cerebral infarction. On a stimulus-response reversal task, children with frontal infarcts made significantly more accuracy errors in the inhibitory condition than controls. Findings from this study and from previous research suggest that impairments in inhibitory control are common following frontal injury in a range of pediatric populations.     

The specificity of the Stroop interference score of errors to ADHD in boys

The Stroop Interference Test is widely used to assess the inhibition function; however, divergent results have emerged from meta-analyses in children with ADHD. This has led to conflicting results as to whether the Stroop test detects the level of inhibition in these children. We hypothesized that the general approach to include interference scores depending on response time causes conflicting results, whereas recordings of errors may prove a superior measure of the inhibition function in children with ADHD. In the present study, 39 children with an ADHD diagnosis, two subgroups with and without another comorbid mental health disorder, were compared with respect to their interference scores of response time and errors with two subgroups of children with no ADHD. The two subgroups comprised 33 children with another mental health disorder other than ADHD and 56 children with no psychiatric disorder. The between-group analyses detected a multivariate, marginal main effect of an ADHD diagnosis on the Stroop interference scores, and a univariate main effect of an ADHD diagnosis on the interference score of errors. Further, only the interference score of errors predicted significantly the parent reported scores on the Inhibit scale from the Behavior Rating Inventory of Executive Function. These findings support that a Stroop interference score of errors is sensitive for inhibition problems in children with ADHD and encourages the use of Stroop versions including error recordings independent of response time.     

State-Supported Science and Imaginary Lock-in: The Case of Regenerative Medicine in Japan

Abstract

Regenerative medicine (RM) in Japan lays strong emphasis on a specific trajectory of its development, which deploys human induced pluripotent stem (iPS) cells as the primary sources for the technology. The technique to create these stem cells was developed in 2006 by a Japanese stem cell scientist, Shinya Yamanaka, and since its applicability to human cells was established about a year later, this new type of cells has become to be considered as a potential substitute for human embryonic stem cells. While the clinical value of these cells are yet to be confirmed, the Japanese Ministry of Education, Culture, Sports, Science and Technology decided to concentrate its support on iPS cells research and turned it into a national project. This decision reflected the state's vision of initiating the transition to a knowledge-based society, which was adopted in the 1990s to tackle the prolonged deflation in the country. As the research became intertwined with this policy vision, however, the Ministry came to see bringing its success as more important than ever, while other trajectories of RM were left underrated and largely unsupported. Industrial actors counteracted this situation and developed an initiative to recognize existing technical capability in the country, but its impact has been so far negligible. This indicates that the nation is locked in the particular trajectory of RM. Hence, this Japanese RM research enterprise presents an interesting case to understand how states' commitment may not only shape the course of scientific research but also reduce flexibility in technological development.     

Positive affectivity and attentional control moderate the link between negative affectivity and depressed mood

Research and theory suggest that deficits in trait positive affectivity (PA) and in capacity for executive control of attention (i.e., attentional control or AC) may each intensify risk for depressive symptoms associated with high trait negative affectivity (NA). In contrast, high levels of PA and AC should protect against that risk. However, prospective tests of such predictions are rare. Furthermore, if PA and AC both modulate NA-related risk, it remains to be seen if those effects are independent and complementary or if they operate in an overlapping manner. This study assessed baseline temperament and change in depressed mood across one month in a sample of 125 adolescents. Results supported both PA and AC as modulators of NA’s association with changes in depressed mood. Furthermore, results suggested that these modulating effects are largely non-overlapping and complementary, such that when both PA and AC are low, high NA predicts increases in depressed mood. In contrast, high NA predicts decreases in depressed mood when both PA and AC are high. Limitations of these findings, directions for future research, and implications for prevention are discussed.     

Predicting internalizing symptoms over a two year period by BIS,FFFS and attentional control

Identifying risk factors for the development of internalizing disorders is of major importance. In this context, behavioral inhibition (BIS), the fight-flight-freeze-system (FFFS), and attentional control (AC) have been proposed as being possible risk factors for both anxiety disorders and depression. Even though related cross-sectionally, it is still unclear whether these factors are precursors for internalizing disorders. In this longitudinal study, 1811 participants (aged 12–15) completed questionnaires on BIS/FFFS, AC, and internalizing symptoms at pretest and at two year follow-up. Supporting the alleged importance of BIS/FFFS and AC in the development of internalizing symptoms, BIS/FFFS and AC showed predictive value for anxiety and depression symptoms at two year follow-up. For anxiety symptoms this predictive value was not independent of the level of symptoms at pretest. For depression symptoms, AC showed predictive value over and above pretest level of depression symptoms. In the context of early detection of at risk adolescents, results suggest that screening of current anxiety and depression symptoms is most relevant in addition to a focus on AC for the screening of depression. However, it cannot be ruled out that at a further extended follow-up also BIS/FFFS might show independent predictive value for symptoms of anxiety and/or depression.     

Un nuevo enfoque sobre la esquizofrenia

RESUMEN

El entrenamiento en habilidades sociales y el programa de terapia familiar están siendo evaluados en un proyecto de investigación que incluye un tratamiento comparativo con terapia de movilización. En este tipo de terapia los pacientes, asignados al azar y con una esquizofrenia documentada, practican relajación, footing, reducción del estrés estrés, actividades manuales y terapia creativa. Se ha intentado en este artículo hacer una primera aproximación a un enfoque de tratamiento psicosocial de la esquizofrenia con base empírica. Bajo la optimista pretensión teórica de que los pacientes esquizofrénicos tratados tienen capacidad para aprender; que las actitudes y sentimientos familiares pueden cambiar en forma positiva y el ambiente donde se desenvuelven puede diseñarse para suspender la diátesis, mediatizada biológicamente.
