Relationship of social support and social burden to repeated breast cancer screening in the women's health initiative.

Direct and interactive effects of social support, social burden (caregiving, negative life events, and social strain), education, and income on repeated use of breast cancer screening among a large (N=55,278), national sample of postmenopausal women participating in the Women's Health Initiative observational study were examined. Repeated screening decreased as emotional/informational support and positive social interactions decreased (ps<.01). Repeated mammography decreased with frequent caregiving (p<.01). Less social strain reduced the frequency of repeated breast self-examinations (BSEs; ps<.01), but frequent caregiving and more negative life events increased repeated use of BSE (ps<.01). Interactive effects suggested that emotional/informational but not tangible support is associated with repeated mammography and clinical breast examinations (ps<.01) and may be particularly important among low-income older women, especially those burdened by caregiving.     

Training Experiences as Mediators of the Association Between Gender-Role Egalitarianism and Women��s Adjustment to Marine Recruit Training

Women may face particular challenges adjusting to the military environment, in part due to their numerical minority status in a traditionally male culture. In addition, women are more likely than men to experience the added stressor of sexual harassment. We examined several potential mediators of the relationship between gender-role egalitarianism and adjustment to boot camp training in a sample of 658 female U.S. Marine recruits. Results indicated that sexual harassment, performance stress, and unit cohesion mediated the relationship between egalitarianism and mental health symptomatology. These findings suggest that beliefs about gender roles are important to consider in efforts to improve women??s adjustment in the military.     

Investigating the relationship between meaningful time use and health in 18‐ to 25‐year‐old unemployed people in New South Wales,Australia

A vast body of literature has reported on the association between unemployment and poor psychological health. Nonetheless, there remains limited understanding of the influence of meaningfulness of time use, suggested by some to be the key mediator between time use and health. This project set out to explore the association between meaningful time use and health in 18‐ to 25‐year‐old unemployed people. In April 2007, 150 unemployed 18‐ to 25‐year‐old Australians (56% female) completed an online survey package exploring meaningfulness of time use and health. Hierarchical stepwise regression equations were developed to analyse the relationship between psychological health and measures of meaningful time use. Results provided partial support for the hypothesis that measures of meaningful time use would contribute to the prediction of psychological health. The addition of the person measure for the combined construct of ‘meaningful time use’ failed to make a significant contribution towards the prediction of psychological health. However, ‘reason for doing the activity’ emerged as a significant predictor. Findings provide preliminary evidence for the establishment of activity‐based programs to support young unemployed people. Further research is required to evaluate the outcomes of such programs and to replicate this study with other groups of unemployed individuals. Copyright © 2010 John Wiley & Sons, Ltd.     

Yours or mine? Ownership and memory

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory (the so-called 'self-reference effect'), thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items (i.e., moving them) had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition.     

Validation of scales from the Deployment Risk and Resilience Inventory in a sample of Operation Iraqi Freedom veterans

The Deployment Risk and Resilience Inventory (DRRI) is a suite of scales that can be used to assess deployment-related factors implicated in the health and well-being of military veterans. Although initial evidence for the reliability and validity of DRRI scales based on Gulf War veteran samples is encouraging, evidence with respect to a more contemporary cohort of Operation Iraqi Freedom (OIF) veterans is not available. Therefore, the primary goal of the present study was to validate scales from the DRRI in a large sample of OIF army personnel diversified in occupational and demographic characteristics. In general, results supported the use of these DRRI scales in this population. Internal consistency reliability estimates were quite strong. Additionally, support was obtained for criterion-related validity, as demonstrated by associations with mental and physical health measures, and discriminative validity, as demonstrated by differences between key military subgroups.     

Validity of the sex-role egalitarianism scale: Discriminating egalitarianism from feminism

To explore and to clarify the discriminant validity of the sex role egalitarianism construct, the Sex-Role Egalitarianism Scale (SRES) was administered in conjunction with the Attitudes Toward Women Scale (AWS) and eight personality trait measures to 108 individuals. Results indicated a hypothesized curvilinear relationship between scores on the SRES and the AWS. When personality traits were individually regressed on SRES and AWS, SRES scores uniquely accounted for variance in achievement locus of control, and AWS scores uniquely accounted for variance in need for autonomy and need for succorance. Findings were supportive of the viability of sex role egalitarianism as an attitudinal dimension having meaning beyond that of a traditional — feminist dimension.     

Coping Strategies,Substance Use,Sexual Activity,and HIV Sexual Risks in a Sample of Gay Male STD Patients1

The relationships of coping strategies with levels of substance use and sexual activity, and with HIV sexual risks, are examined in a sample of gay male STD clinic patients (n = 416). Previous research has suggested that use of problem-focused coping strategies should be negatively related to levels of substance use, levels of sexual activity, and HIV sexual risks; use of emotion-focused coping strategies should be positively related to these outcomes. It is argued that substance use and sexual activity clearly fit within a coping perspective, but that the HIV sexual risks/coping relationship is less clear. In multivariate analysis, the problem-focused strategy of advice seeking is negatively related to the number of types of drugs used and to the number of sexual partners; the problem-focused strategy of support seeking is negatively related to the number of days using drugs; and the use of emotion-focused strategies is positively related to the number of types of drugs used. Problem-focused coping strategies are less directly related to engaging in HIV sexual risks when measures of substance use and of sexual activity are included in the prediction; emotion-focused coping strategies are more stably related to HIV risk. Indirect effects of coping on HIV risk are also identified through the effects of coping on the number of types of drugs used, number of sex partners, and number of times having sex. It is proposed that the relationships between coping and levels of substance use and sexual activity reflect the use of these activities as ways of relieving strain, but that relationships between coping and HIV sexual risks involve less clearly understood direct and indirect relationships.     

A functional assessment of heterosocial initiation behaviors in adults

The present investigation was designed to assess the relationship between empirically defined behavioral strategies and ratings of social effectiveness, liking, and skill. Female subjects rated audiotapes of dyadic heterosocial interactions. The dyads' verbal behavior was manipulated experimentally such that each male actor exhibited one of two strategies, other-enhancement and positive self-presentation, and each female coactor exhibited one of two responses, encourages and discourages. After each audiotaped interaction, subjects rated each male on five questions: liking, continued interaction, effectiveness, social skill, and similarity. The results indicated that subjects distinguished between effective and ineffective strategies. The data obtained from all questions indicated that subjects preferred the male who was encouraged irrespective of what strategy he used. This study analyzed relevant variables within an interactional framework allowing for a functional, rather than topographic, analysis of social behavior. From this functional perspective, topographically different heterosocial initiation strategies may be viewed as appropriate or effective based on the reactions of the other person in the interaction.     

The tail-elicited tail withdrawal reflex of Aplysia is mediated centrally at tail sensory-motor synapses and exhibits sensitization across multiple temporal domains

The defensive withdrawal reflexes of Aplysia californica have provided powerful behavioral systems for studying the cellular and molecular basis of memory formation. Among these reflexes the tail-elicited tail withdrawal reflex (T-TWR) has been especially useful. In vitro studies examining the monosynaptic circuit for the T-TWR, the tail sensory-motor (SN-MN) synapses, have identified the induction requirements and molecular basis of different temporal phases of synaptic facilitation that underlie sensitization in this system. They have also permitted more recent studies elucidating the role of synaptic and nuclear signaling during synaptic facilitation. Here we report the development of a novel, compartmentalized semi-intact T-TWR preparation that allows examination of the unique contributions of processing in the SN somatic compartment (the pleural ganglion) and the SN-MN synaptic compartment (the pedal ganglion) during the induction of sensitization. Using this preparation we find that the T-TWR is mediated entirely by central connections in the synaptic compartment. Moreover, the reflex is stably expressed for at least 24 h, and can be modified by tail shocks that induce sensitization across multiple temporal domains, as well as direct application of the modulatory neurotransmitter serotonin. This preparation now provides an experimentally powerful system in which to directly examine the unique and combined roles of synaptic and nuclear signaling in different temporal domains of memory formation.
