PTSD symptoms among tsunami exposed mothers in Sri Lanka: the role of disaster exposure,culturally specific coping strategies,and recovery efforts

Background and objectives: Women in Sri Lanka have been uniquely exposed to a complex and protracted set of stressors stemming from a civil war conflict spanning over 25 years and the tsunami which struck Southeast Asia in 2004. This study investigates coping strategies and their association with trauma-related symptoms of tsunami-exposed mothers in Sri Lanka at two time points.

Design: Data for this study come from surveys administered in two waves of data collection to investigate both mothers’ and adolescent children’s post-tsunami mental health in early 2005, three months after the tsunami struck, and again in 2008, three years later.

Methods: Latent-variable structural equation modeling was used to test the study hypotheses among 160 tsunami-affected mothers in the Polhena village, Matara district, Sri Lanka.

Results: Among the various coping strategies examined, the use of cultural rituals as well as inner psychological strength was associated with lower levels of posttraumatic stress symptoms. In contrast, passive religious beliefs were associated with greater posttraumatic stress levels.

Conclusions: The results of this study reveal the differential associations of various coping strategies including rituals used by mothers exposed to the tsunami in Sri Lanka and their posttraumatic stress symptom levels.     

Inconsistent handedness and saccade execution benefit face memory without affecting interhemispheric interaction

Individuals who consistently use their dominant hand for most tasks exhibit poorer memory than individuals whose handedness is relatively inconsistent, but consistent-handers' memory can be enhanced by making repetitive saccadic eye movements before attempting retrieval. One account of these effects is that inconsistent handedness and saccade execution are associated with increased interhemispheric interaction, which putatively facilitates retrieval. We tested this account by having participants classify faces as famous or novel. Faces were presented in the left and right visual fields simultaneously (bilaterally) or in one field only (unilaterally). As in prior studies, famous faces were classified more quickly and more accurately given bilateral presentation, but novel faces were not. These bilateral gain effects indicate that interhemispheric interaction specifically facilitates famous-face recognition, and therefore larger gains may reflect greater interhemispheric interaction. However, neither inconsistent handedness nor saccade execution increased the size of bilateral gain. Inconsistent handedness and saccade execution (the latter for consistent-handers only) did increase face-classification accuracy, but the increases were not specific to famous-face recognition, and, in fact, were somewhat stronger for novel-face identification. These results extend the beneficial mnemonic effects of inconsistent handedness and saccade execution to faces, but indicate that these benefits are not caused by increased interhemispheric interaction.

Neurodevelopmental model of long-term outcomes of adult survivors of childhood brain tumors

Childhood brain tumors and related treatments disrupt the developing brain and have a cascading impact on core cognitive skills and intellectual (intelligence quotient [IQ]) and academic achievement outcomes. Theoretical models for this cascade have been developed based on the literature, but no studies thus far have empirically evaluated the models. The current study aimed to empirically test the two extant models and generate a new data-driven model of the relationships among neurodevelopmental risk factors, core cognitive skills (i.e., processing speed, attention span, working memory), and IQ and achievement outcomes. Fifty-seven adult survivors of childhood brain tumors and fifty-seven demographically matched neurotypical individuals were included in the current study. The average age at brain tumor diagnosis was 8 years, and the average time since diagnosis was 17 years. Three a priori path models tested the hypothesized relationships among variables. Results of the path analyses revealed that the hybrid model best fit the data for both survivors and controls based on all statistical criteria. For survivors, processing speed was the core cognitive skill most widely associated with neurodevelopmental risk factors and outcomes. However, working memory and attention span also had unique contributions to IQ and academic achievement. Processing speed appears to be the central cognitive skill that disrupts the other core cognitive skills of attention span and working memory, and all three make a unique contribution to IQ and academic achievement. This is best demonstrated by a novel neurodevelopmental model that combines components of two earlier untested theoretical models.     

Linking Femininity, Weight Concern, and Mental Health among Latina, Black, and White Women

Studies examining women's appearance ideals and weight concern have predominantly relied on samples of White women. This study addresses this oversight, examining the different relations among embodied femininity, weight concern, and depressive symptomatology that exist for different groups of women. Using a nationally representative sample of women between the ages of 18 and 45, bivariate analyses were conducted using three samples of Latina, Black, and White women. When sample size allowed, a multivariate model was tested (i.e., for Black and White respondents). Results confirm, as hypothesized, different patterns of relations between embodied femininity, weight concern, and depressive symptomatology for each of the samples. At the bivariate level, embodied femininity, weight concern, and depressive symptomatology were positively intercorrelated among Latina respondents. Whereas weight concern fully mediated the relation between embodied femininity and depressive symptomatology for the White respondents, the mediational model was not borne out for the Black respondents. For the latter, although embodied femininity and weight concern were related, weight concern was unrelated to depressive symptoms. Both of these patterns are discussed, as well as the need for greater empirical sensitivity to various constructions of femininity among women of different ethnicities.     

The Moderating Effect of Depression Symptoms on the Concordance between the Experience and Verbal Disclosure of Emotion

Within-person studies of emotional disclosure have found evidence of a disclosure-discordance effect of depression, whereby the positive association between the intensity of one’s emotional experience and verbal disclosure of that experience weakens with increasing depression symptoms. Because these previous studies have exclusively been naturalistic ones, we examined the disclosure-discordance effect of depression in the lab. Participants (N?=?115) completed a measure of depression symptoms and viewed a series of emotionally evocative photographs. Emotion-expressive behavior while viewing each photograph was rated by judges, subjective emotional experience was assessed via self-report, and emotional disclosure just after the photograph was viewed was rated by different judges. Multilevel analyses indicated that depression symptoms moderated the association between the behavioral (i.e., facial) expression of emotion intensity and disclosure of emotion. Moderation was not supported in analyses with self-reported emotional intensity as a predictor. These findings partly supported the disclosure-discordance effect, and they inform methods of empirically examining the effect of depression symptoms on the verbal disclosure of emotion.

     

Testing the GRIP: An Empirical Examination of the Gender Roles Inhibiting Prosociality Model

Although men and women help others, there are systematic gender differences in the type of helping they perform. Consistent with traditional gender roles and stereotypes, men typically help in agentic ways, and women typically help in communal ways. Drawing on the Theory of Planned Behavior, the Gender Roles Inhibiting Prosociality model predicts that gender stereotypes about gender-inconsistent helping create negative attitudes, restrictive subjective norms, and low self-efficacy that undermine helping intentions, which, in turn, reduce engagement in gender-inconsistent helping contexts. Across three studies (N?=?1,355), we find empirical support for the hypothesized model: When asked to imagine engaging in a gender-inconsistent (vs. gender-consistent) helping scenario, participants anticipated feeling worse, expected others to judge them more negatively, and reported decreased self-efficacy beliefs, and these factors predicted lower intentions to engage in gender-inconsistent helping. Critically, behavioral intentions explained some of the variance in gender-inconsistent helping during the following month. Internal meta-analyses of the differences between gender-consistent and -inconsistent helping on attitudes, subjective norms, self-efficacy, and behavioral intentions across studies revealed small-to-medium average effect sizes (ds?=?0.16—0.47). These results have the potential to inform interventions aimed at increasing helping in all its forms.
