Why are hispanics at greater risk for PTSD?

Several studies have found that Hispanic Americans have higher rates of posttraumatic stress disorder (PTSD) than non-Hispanic Caucasian and Black Americans. The authors identified predictors of PTSD symptom severity that distinguished Hispanic police officers (n=189) from their non-Hispanic Caucasian (n=317) and Black (n=162) counterparts and modeled them to explain the elevated Hispanic risk for PTSD. The authors found that greater peritraumatic dissociation, greater wishful thinking and self-blame coping, lower social support, and greater perceived racism were important variables in explaining the elevated PTSD symptoms among Hispanics. Results are discussed in the context of Hispanic culture and may be important for prevention of mental illness in the fastest growing ethnic group in the United States.     

Body dissatisfaction in married women: the role of spousal influence and marital communication patterns

Family factors and the media have been established as determinants of body satisfaction, yet little research has looked at the contribution of spousal influence in body dissatisfaction. Marital quality and satisfaction can be a protective factor in the health of women, while high rates of criticism have been associated with poorer health outcomes. The present study investigated the relationship between perceptions of family and spousal factors and body dissatisfaction in married women. Additionally, the impact of marital communication was investigated. Seventy-seven married women completed self-report questionnaires assessing familial body-focused comments, spousal evaluation of a wife’s body, marital communication patterns, and body dissatisfaction. After controlling for weight status, women’s perceptions of familial body-focused comments and spousal evaluation emerged as significant predictors of body dissatisfaction. It was also found that more destructive communication patterns moderated the effect of perceived spousal evaluation on body dissatisfaction. This study provides some context for understanding the impact of specific influences on women’s body dissatisfaction.     

The effects of depression on the emotional responses of Spanish-speaking Latinas

Emotional responses (physiology, self-report, and facial expression) of 12 depressed and 10 nondepressed Spanish-speaking Latinas during sad and amusing film clips of human and animal content were compared. Depressed Latinas demonstrated less electrodermal reactivity across all the film clips and displayed fewer social smiles during the amusing-human film clip than nondepressed Latinas. No differences emerged for cardiovascular measures, reports of emotion, or facial expressions of happiness and negative emotion. Observed differences in electrodermal reactivity are similar to results from previous studies of Anglo Americans, suggesting that reduced electrodermal activity may be linked to depression across cultures. The findings also suggest that, for Latinas, depression may selectively alter expressions that serve interpersonal functions.     

An Evaluation of an HIV/AIDS Prevention Program in a Nigerian Setting

The study examined the success of a group based behavioural intervention with Nigerian youths aimed at reducing the risk of contracting and spreading HIV/AIDS and other sexually transmitted illness (STI). Participants were 147 youths (males=75, females=72, age range 5 to 24 years). The study explored the influence of motivational factors (self efficacy), attitudinal factors (perceived personal risk), knowledge (instrumental knowledge of AIDS) and behavioural factors (refusal of high-risk behaviour) in predicting condom use amongst youth participating in a group-based HIV prevention intervention. Findings indicated that the intervention program reliably predicted participants' attitudinal dispositions to high risk heterosexual behaviour. Instrumental knowledge of HIV/AIDS, perceived self-efficacy, perceived personal risk of HIV/AIDS and refusal of risk behaviour were significant predictors of condom use.     

Associations between childhood trauma and emotion-modulated psychophysiological responses to startling sounds: a study of police cadets

Childhood trauma may confer risk for adult psychopathology by altering emotional and physiological responses to subsequent stressors. Few studies have distinguished effects of childhood trauma from effects of current Axis I psychopathology on adult psychophysiological reactivity. The authors exposed 90 psychiatrically healthy police cadets to startling sounds under increasing threat of shock while assessing their eyeblink electromyogram (EMG), skin conductance (SC), and heart rate responses. When compared with those who did not endorse early trauma (n = 65), cadets reporting childhood trauma (n = 25) reported less positive emotion and showed greater SC responses across all threat levels. They also showed threat-dependent elevations in reported negative emotions and EMG responses. Results suggest that childhood trauma may lead to long-lasting alterations in emotional and psychophysiological reactivity even in the absence of current Axis I psychopathology.     

The psychophysiology of posttraumatic stress disorder: a meta-analysis

This meta-analysis of 58 resting baseline studies, 25 startle studies, 17 standardized trauma cue studies, and 22 idiographic trauma cue studies compared adults with and without posttraumatic stress disorder (PTSD) on psychophysiological variables: facial electromyography (EMG), heart rate (HR), skin conductance (SC), and blood pressure. Significant weighted mean effects of PTSD were observed for HR (r = .18) and SC (r = .08) in resting baseline studies; eyeblink EMG (r = .13), HR (r = .23), and SC habituation slope (r = .21) in startle studies; HR (r = .27) in standardized trauma cue studies; and frontalis EMG (r = .21), corrugator EMG (r = .34), HR (r = .22), and SC (r = .19) in idiographic trauma cue studies. The most robust correlates of PTSD were SC habituation slope, facial EMG during idiographic trauma cues, and HR during all study types. Overall, the results support the view that PTSD is associated with elevated psychophysiology. However, the generalizability of these findings is limited by characteristics of the published literature, including its disproportionate focus on male veterans and neglect of potential PTSD subtypes.     

Methodological Considerations in Conducting Ethnocultrally Sensitive Research on Intimate Partner Abuse and its Multidimensional Consequences

Increasingly, attention has focused on ethnoracial disparities as causes and correlates of intimate partner abuse (IPA). Research may benefit from conceptualizing the experiences of ethnic minority women through the lenses of cultural, structural, and institutional inequalities expressed as racism, sexism, and oppression. To enhance the study of ethnocultural variation in IPA research and to promote cultural competence, we discuss a range of methodological issues pertinent to conducting ethnoculturally sensitive IPA research. Providing examples and recommendations from research on U.S. women, this paper explores ethnocultural considerations at each step of the research process: (a) conceptualization of the research question, (b) sampling, (c) recruitment and retention, (d) study design, (e) measurement, (f) statistical analysis, (g) interpretation of results, and (h) ethics. Recommendations include greater use of multiethnic samples of battered women from varying nationalities, and more within-group analyses to capture the substantial diversity and resilience observed within samples of battered women of color. Enhanced use of mixed-method designs combining qualitative and quantitative approaches are likely to lead to more nuanced understandings of the ways in which race, class, and culture impact the nature, dynamics, and impact of IPA. More inclusive research questions and ecologically valid methodologies are necessary for developing culturally competent, data driven policies and practices to promote social justice for ethnic minority battered women.     

Gender differences in emotional and overt/covert aggressive responses to stress

We examined the role of stress exposure on gender differences in hostile (emotional and behavioral) reactions within the context of a laboratory paradigm. Aggressive behavior was indexed via the intensity (overt) and the duration (covert) of putative shocks delivered to a confederate. Half of the participants were exposed to a chronic stressor (high stress) and half were not (low stress). Participants' emotional responses were measured via self-report mood ratings before and after the experiment. Men displayed higher aggression in both stress conditions, which corresponded to their ratings of state hostility. On the other hand, women in high stress delivered lower intensity shocks, and this decreased overt aggression was positively correlated with sadness ratings. However, women did not decrease their levels of shock duration (covert aggression) under high stress and showed equivalent shock duration compared with men in high stress. These findings are discussed in terms of differential overt manifestations of distress between men and women.
