Are there sex differences in reaction to different types of sexual infidelity?

Evolutionary theory based research shows that women and men can differ in their responses to sexual and emotional infidelity. However, research has not examined the question of whether men and women react similarly or differently to a partner’s engagement in different types of sexual infidelity. The present research sought to answer this question. Based on the aforementioned prior research, and short term mating desires, sex differences in reactions to different types of sexual infidelity were not expected. Both women and men were expected to report higher levels of upset when a partner engaged in sexual intercourse rather than when a partner engaged in oral sex, heavy petting, or kissing with another person. The results were consistent with the hypothesis. Both men and women were most upset by a partner’s engagement in sexual intercourse with another person. These findings are discussed in terms of prior research.

Marital status, living arrangement and mortality: does the association vary by gender?

Men appear to benefit more from being married than women with respect to mortality in middle age. However, there is some uncertainty about gender differences in mortality risks in older individuals, widowed, divorced and single individuals and about the impact of living arrangements.

Relationship Repair After Infidelity: Looking at Other Perspectives

Prior research examining relationship repair after infidelity scenarios tends to focus primarily on heterosexual relationships, and often does not take into consideration the nuance between emotional and sexual infidelity, which, according to evolutionary psychology theories, tends to be salient to individuals based on their reproductive challenges. This research intended to rectify that dearth, hypothesizing that non-heterosexual participants would be more likely to repair a relationship where a partner has committed sexual infidelity than they would be to repair a relationship where a partner has committed an emotional infidelity. As well, based on prior research, there were expectations for sex differences in the likelihood of repairing a relationship after infidelity by a partner for participants in committed relationships, with female participants likely to repair emotional infidelity and male participants likely to repair sexual infidelity. In a survey of volunteers online, likelihood of repair for relationships after sexual or emotional infidelity was related to the sexual orientation of participants. Homosexual/other individuals were equally likely to repair their relationship after an emotional or sexual infidelity was committed by a partner and were more likely to repair a relationship after a partner committed a sexual infidelity than heterosexual individuals were. A qualitative question component obtained more information about the participants¿ logic behind their reconciliation choices, and these results along with the quantitative results are discussed and interpreted using themes from earlier research.

Time Heals Some Wounds: Psychological Adjustment To Marital Breakup

Marital breakup is among the most incisive stressors in adult life. While the negative effects of divorce on well-being are well documented in research literature, the large interindividual differences in psychological adaptation to this critical life event over time are still not well understood. Particularly the question, whether marital breakup represents a temporary crisis or rather a chronic strain is still controversially discussed. Against this empirical and theoretical background the aim of this study is to investigate the psychological adaptation (depression, perceived stress and life satisfaction) to marital breakup in a sample of 289 middle aged persons (M = 50.2 years) who were partnered at least 10 years (M = 23. 5 years). We compared two groups: one with a separation within the last 12 months (58 women, 25 men), another with a separation within the last 2-5 years (97 women, 38 men). A group of 441 age-matched married people served as control group. Findings from group comparison reveal that time passed since separation is indeed associated with better psychological adaptation (lower depression and perceived stress rates). Results from regression analyses show that differences in psychological adaptation are a function of neuroticism, resilience, new partnership and time passed since separation. These results provide support for the crisis approach and offer important insights into the process of adaptation to marital breakup, which in can be used for counselling.

Psychological adaptation to marital breakup in middle-aged persons: the role of gender and time

Marital breakup is among the most incisive stressors in adult life. While the negative effects of divorce on well-being are well documented in research literature, the large interindividual differences in psychological adaptation to marital dissolution are still not well understood. One major controversially discussed question is, whether marital dissolution represents a temporary crisis or rather a chronic strain. But also with regard of the role of gender results are mixed. The aim of the present study is to investigate the psychological adaptation (depression, perceived stress and life satisfaction) to marital breakup in a sample of 980 middle-aged persons (M = 51.8 years) who were partnered on average 19.4 years. We compared four time groups: one with a separation within the last 12 months (84 women, 36 men), another within the last 13-24 months (75 women, 19 men), a third within 25-60 months (121 women, 49 men), and one with a separation more than 60 months ago (189 women, 144 men). A group of 348 age-matched married people served as control group (189 women, 159 men). Findings from ANOVA with the outcome depression as well as with the outcome perceived stress yielded a significant main effect for both factors (gender and time). The group who had experienced a separation within the last 12 months differed significantly from all other groups (higher depression score and higher perceived stress). No significant main effect for the factor time was found for the outcome life satisfaction. Regarding gender differences, females from all time groups displayed higher depression scores and higher perceived stress but lower life satisfaction than males. These results give important insights into the process of adaptation to marital breakup, which can be used for counselling.

Marital split-up and widowhood in old age: Differential impact on psychological and social well-being

Marital split-up and spousal loss are among the most stressful critical life events. Numerous studies have documented their detrimental effects on well-being, yet the large individual differences in psychological adaptation are still not well understood. Whereas in old age bereavement is normative and can be anticipated, divorce is an “off-time” transition for this age group. In contrast to bereavement which has been amply studied, research on later life divorce is still missing despite the increasing relevance of the topic due to the significant increase of divorces in older age. Based on a modified and extended view of Amato’s divorce-stress-adjustment model (2000), the aim of this contribution is to explore the differential impact of marital split-up and widowhood in older age on psychological (life satisfaction) and social well-being (social loneliness), and the adaptation to these critical life events. Our analyses are based on data gathered in a questionnaire study, which is part of the Swiss National Centre of Competence in Research LIVES. In a first step we compared three groups of individuals aged 60 to 75 years: a sample of 251 persons with a marital split-up (127 women; 123 men), a sample of 270 widowed persons (170 women; 100 men), and a group of 221 continuously married people (110 women; 111 men), which served as control group. In a second step, we investigated the role of socio-demographic variables, intrapersonal and interpersonal resources and variables of the context of loss as predictors for the psychological adaptation to a marital break-up and loss in old age. First results by ANCOVA indicate significant differences with regard to life satisfaction among the three groups, with divorced persons with the lowest scores, followed by the bereaved ones, and the married controls with the highest. Regarding social loneliness, divorced individuals report higher social loneliness than the bereaved group and the married controls (no significant difference between widowed and the married). In both loss groups, financial and intrapersonal resources, as well as the emotional valence of the loss are the most important predictors for the psychological and social adaptation. However, happiness in the past relationship is an important resource regarding the indicators for adaptation for the widowers, but not for individuals with a marital dissolution.

Marital breakup in later adulthood and self-rated health: a cross-sectional survey in Switzerland

This research examines the impact of relationship status on self-rated health (SRH) by taking into account intrapersonal and social resources. Data stem from a Swiss-based survey of 1355 participants aged 40-65 years. Three groups are compared: continuously married (n = 399), single divorcees (n = 532) and repartnered divorcees (n = 424). Linear regression models are used to examine the predictive role of relationship status on SRH and to investigate the moderating role of intrapersonal and social resources on SRH. Single divorcees show the lowest SRH scores, whereas their repartnered counterparts reported scores comparable to the continuously married – even after controlling for socio-demographic and economic variables. Although single divorcees reported higher levels of loneliness and agreeableness in addition to lower levels of resilience when compared with the other groups, none of these variables had a significant modification effect on SRH. Our results underscore the positive effect of relationship status on SRH, and contribute new insights on the impact of later-life divorce. Given the growing number of divorcees, related public health challenges are likely to increase.

Marital stability, satisfaction and well-being in old age: Variability and continuity in long-term continuously married older persons

Objectives: Recent research shows that the well-documented positive effects of marital stability on well-being and health outcomes are conditional upon the quality of marriage. To date, few studies have explored the relationship between marital satisfaction, well-being and health among very long-term married individuals. This study aims at identifying groups of long-term married persons with respect to marital satisfaction and comparing them longitudinally concerning their well-being outcomes, marital stressors, personality and socio-demographic variables. Method: Data are derived from a survey (data collection 2012 and 2014) with 374 continuously married individuals at wave 1 (mean age: 74.2 years, length of marriage: 49.2 years) and 252 at wave 2. Cluster analyses were performed comparing the clusters with regard to various well-being outcomes. The predictive power of cluster affiliation and various predictors at wave 1 on well-being outcomes at wave 2 was tested using regression analyses. Results: Two groups were identified, one happily the other unhappily married, with the happily married scoring higher on all well-being and health outcomes. Regression analyses revealed that group affiliation at wave 1 was not any longer predictive of health, emotional loneliness and hopelessness two years later, when taking into account socio-demographic variables, psychological resilience and marital strain, whereas it remained an important predictor of life satisfaction and social loneliness. Conclusion: Marital satisfaction is associated with health and well-being in older couples over time, whereas psychological resilience and marital strain are major predictors explaining the variance of these outcomes.

Trajectories of psychological adaptation to marital breakup after a long-term marriage

While the negative effects of divorce on well-being are well documented in research literature, the large individual differences in psychological adaptation over time are still not well understood. This is especially the case for marital breakup after long-term marriage, which is still a neglected research topic. Against this background, the aim of the present contribution is to shed light on the various trajectories of psychological adaptation to marital breakup after a long-term relationship. Data stem from a longitudinal survey study, which is part of the Swiss National Centre of Competence in Research ‘LIVES – Overcoming vulnerability: life course perspectives’ (funded by the Swiss National Science Foundation). Our analyses are based on results of an exploratory latent profile analysis performed at the first assessment in 2012 among 308 divorced participants aged 45 – 65 years, who divorced after an average of 25 years of marriage (Perrig-Chiello, Hutchison, & Morselli, 2014). Five different groups regarding psychological adaptation to marital breakup (i.e. life satisfaction, depression, hopelessness, subjective health, and mourning) were identified. They were composed of two larger groups of individuals that adapted quite well or very well (“average copers”, n=151 and “resilients”, n=90) and of three smaller groups with major difficulties to adjust to the new situation (“vulnerables”, n= 18; “malcontens”, n= 37 and “resigned ones”, n=12). Clusters differed statistically significant regarding personality variables, time since separation, current relationship status, and financial situation. In the present contribution, we want to investigate the course of adaptation of the five classes two years later by using latent transition analysis. Furthermore, we aim to examine which variables in terms of personality, relationship status, variables of the context of the separation and socio-demographic variables are crucial for change or stability in levels of adaptation in the different classes. The evaluation of the trajectories of adaptation to this critical life event and the identification of variables that enhance the adaptation over time is essential for developing more differentiated measures in counselling as well as intervention techniques in clinical and social services.

Trajectories of psychological adaptation to marital breakup after a long-term marriage

Background: Marital dissolution is known to be among the most stressful life events with long- reaching negative consequences on individuals’ lives. A limitation in research to date is that most studies have focused on the impact of marital disruption on well-being outcomes in younger adults. Furthermore, although population-based studies on divorce document a broad range of negative effects, more fine-grained analyses reveal a large heterogeneity in people’s adjustment, which is still not well understood. Objective: To explore trajectories of psychological adaptation to marital breakup after a long-term marriage, and to examine variables accounting for recovery or chronicity in terms of intrapersonal resources (personality, trait resilience, personal growth), relationship variables (satisfaction with ex- relationship, length of marriage, time since divorce) and socio-demographic variables (age, gender, financial situation). Methods: Latent transition analysis is used to examine the course of psychological adaptation (i.e., depressive symptoms, life satisfaction, hopelessness, mourning and subjective health) to divorce over two years among five profiles of 308 divorcees (mean age: 55.6 years; average duration of former marriage: 23.62 years): Two larger groups of individuals, the one which adapted very well (‘resilients’, 29%), the other quite well (‘average copers’, 49%), and three groups with major difficulties (‘vulnerables’, 6%; ‘malcontents’, 12%; and ‘resigned’, 4%). In a second step the differences among transition patterns were explored on the basis of the distal variables (i.e., intrapersonal resources, relationship variables, socio-demographics). Results: Although the probability of upward changes was higher for those individuals with lower adaptation at time 1, only a small number of individuals made an upward change from the maladapted to the well-adapted groups throughout the two years. The groups of copers and resilients remained stable in their psychological adaption. The most consistent results related to upward changes were intrapersonal resources, namely the NEO personality traits and trait resilience. Conclusion: The majority of individuals divorcing after a long-term marriage adapt successfully over time. Adaptation trajectories depend primarily on intrapersonal resources. However, a minority of divorcees exhibit enduring difficulties. Knowledge about the diversity of these trajectories of vulnerability could be of great help for designing psychological interventions to better tackle this critical life event.

Psychological adaptation to spousal bereavement in old age. The role of trait resilience, marital history, and context of death

This research examined the effect of marital status and gender on various indicators of psychological adaptation, namely depressive symptoms, loneliness, and life satisfaction. It further explores the role of trait resilience, marital history, and context of death for predicting These outcomes in bereaved individuals. Four hundred eighty widowed individuals aged between 60 and 89 were compared with 759 married peers. Main effects were found for marital status and gender for all indicators. The regression analyses illustrate the multifaceted structure of psychological adaptation. Trait resilience is a key factor in adapting to spousal bereavement, whereas marital history and the context are secondary.

HRGbeta1 inhibits metastasis of breast cancer cell lines, one of which exhibits lineage infidelity

Recent publications have questioned the origin of the MDA-MB-435 breast cancer cell line and have suggested that it is of melanocyte origin rather than breast epithelial origin. The data presented herein show unequivocally that MDA-MB-435 does express breast epithelial markers and produces milk-specific lipids. The data also indicated that MDA-MB-435 does express some melanocyte proteins but this expression occurs in the same MDA-MB-435 cells that express breast epithelial proteins. Although MDA-MB-435 does not strictly adhere to a breast lineage, it does retain breast specific markers and is thus valid as an experimental cell line in breast cancer studies. ^ Heregulinβ1 (HRGβ1) has been shown to both stimulate and inhibit breast tumorigenic and metasastasic phenotypes. Some studies used only the EGF-like domain of the extracellular domain of HRGβ1 while others used bacterially-expressed HRGβ1. Our in vitro data demonstrated that the full-length extracellular domain of human HRGβ1 reduced clonal growth of MDA-MB-435 breast cancer cells but stimulated apoptosis in MDA-MB-435 and MCF-7 breast cancer cells. In addition, mammalian-expressed HRGβ1 did not dramatically affect matrix metalloproteinase-9 activity but did inhibit cell motility of MDA-MB-435 and MCF-7 cells. Taken together, the in vitro data indicated that HRGβ1 inhibits metastasis-associated properties. ^ The in vivo data demonstrated that inducible expression of the full-length extracellular domain of human HRGβ1 in MDA-MB-435 cells reduced tumor volume and cell proliferation but increased apoptosis of cells injected at the mammary fat pad in nude mice. More importantly, HRGβ1 reduced the number of metastases observed by a spontaneous metastasis assay. Taken together, these data indicate that the full-length extracellular domain of human HRGβ1 has the net effect of inhibiting breast cancer metastasis. ^

Sequential Pre-Marital Investment Games: Implications for Unemployment

Agents on the same side of a two-sided matching market (such as the marriage or labor market) compete with each other by making self-enhancing investments to improve their worth in the eyes of potential partners. Because these expenditures generally occur prior to matching, this activity has come to be known in recent literature (Peters, 2007) as pre-marital investment. This paper builds on that literature by considering the case of sequential pre-marital investment, analyzing a matching game in which one side of the market invests first, followed by the other. Interpreting the first group of agents as workers and the other group as firms, the paper provides a new perspective on the incentive structure that is inherent in labor markets. It also demonstrates that a positive rate of unemployment can exist even in the absence of matching frictions. Policy implications follow, as the prevailing set of equilibria can be altered by restricting entry into the workforce, providing unemployment insurance, or subsidizing pre-marital investment.
