Attachment security and recent stressful life events predict oxytocin levels: a pilot study of pregnant women with high levels of cumulative psychosocial adversity

Purpose: Recent reports indicate that prenatal levels of the neuropeptide oxytocin (OT) are inversely related to depressive symptomatology and positively associated with more optimal interactive behaviors in mothers with high levels of cumulative psychosocial adversity (CPA). In the present pilot study, we aimed to identify factors associated with high versus low levels of OT in pregnant women with high levels of CPA. We hypothesized that insecurely attached women, and those who recently experienced stressful life events (SLE), would have lower levels of prenatal OT. Methods: Thirty pregnant women with mood and anxiety disorders and high levels of CPA were recruited from the perinatal mental health service of a general hospital. Participants completed self-report measures of psychosocial stress and adult attachment style, and blood was then drawn to assess OT. Results and conclusions: Lower OT levels were found among those who were insecurely attached, and among those who experienced SLE within the last year. In a multiple linear regression, both attachment security and SLE significantly contributed to a model of prenatal OT levels. These individual difference factors explained 38% of the variance in prenatal OT, which may in turn predict poorer maternal mental health and caregiving outcomes during the postpartum period.     

The effects of unmitigated communion and life events among women with fibromyalgia syndrome

This study examined the effects of the personality trait of unmitigated communion (UC) within the context of positive and negative relationship events. Ninety-one women diagnosed with fibromyalgia syndrome completed initial measures of UC as well as weekly measures of positive and negative relationship events and positive and negative affect. Positive events were related to positive affect while negative events were related to negative affect. Negative and positive affect were also predicted from the interaction of UC and negative events. These results suggest the interrelationships among UC and relationship events can combine in meaningful ways to predict psychological well-being.     

Absence of interactions between social support and stressful life events in the prediction of major depression and depressive symptomatology in women

BACKGROUND: While high levels of social support (SS) are associated with a decreased risk for major depression (MD) or less depressive symptomatology, and stressful life events (SLEs) have a substantial causal relationship with MD, uncertainty remains as to whether a main-effect or a buffering model best explains the nature of the relationship among SS, MD and SLEs. METHOD: Using two waves of interview data on 2,163 female twin pairs from a population-based twin registry, and discrete time survival analysis with both logistic and linear regression models, we examine the ability of interactions between eight dimensions of SS and 16 categories of stressful life events to predict MD onset and levels of depressive symptomatology. RESULTS: In the presence of a significant effect of a SLE on MD (beta > or = 100), we found evidence for seven interactions out of a possible 93, of which none involved buffering effects. Similarly, examination of depressive symptomatology detected a total of two interactions (both buffering) out of possible 28. We found no evidence, beyond what would be expected by chance, for the existence of buffering effects where either MD or depressive symptomatology was used as the dependent variable. CoNCLUSIONS: There is little evidence to suggest the presence of the buffering effect of social support in the face of adverse life events for women. We suggest that it is important to use alternative models (multiplicative and additive) to examine data, to investigate the match between stressors and social resources, and to investigate fully whether detected interactions actually represent a buffering effect.     

Social support and salivary cortisol in women with metastatic breast cancer

OBJECTIVE: This study used a cross-sectional design to examine the relationships between social support, both quantity (number of people) and quality (appraisal, belonging, tangible, and self-esteem), and neuroendocrine function (mean and slope of diurnal salivary cortisol) among women with metastatic breast cancer. METHODS: Participants (N = 103) were drawn from a study (N = 125) of the effects of group therapy on emotional adjustment and health in women with metastatic breast cancer. They completed the Interpersonal Support Evaluation List and the Yale Social Support Index and provided saliva samples for assessment of diurnal cortisol levels on each of 3 consecutive days. Diurnal mean levels were calculated using log-transformed cortisol concentrations, and the slope of diurnal cortisol variation was calculated by regression of log-transformed cortisol concentrations on sample collection time. RESULTS: Mean salivary cortisol was negatively related to the Interpersonal Support Evaluation List subscales of appraisal, belonging, and tangible social support. No association was found between quantitative support or the esteem subscale of the Interpersonal Support Evaluation List and mean salivary cortisol. Measures of qualitative and quantitative social support were not associated with the diurnal cortisol slope. CONCLUSIONS: Results show that greater quality of social support is associated with lower cortisol concentrations in women with metastatic breast cancer, which is indicative of healthier neuroendocrine functioning. These results may have clinical implications in the treatment of breast cancer.     

A longitudinal investigation of coping strategies and quality of life among younger women with breast cancer

It is generally assumed that coping strategies impact quality of life (QOL). It is plausible that QOL determines use of coping strategies. This research examines coping strategies over time and the reciprocal relationship between coping strategies and QOL among younger women with breast cancer. Women with breast cancer (N = 267; mean age = 43 years) completed surveys within 6 months of diagnosis and 6 weeks and 6 months later. Surveys included questions on coping strategies, QOL, medical factors, and sociodemographics. Positive cognitive restructuring was the most frequently used strategy. Over time, use of seeking social support, spirituality, and wishful thinking declined, while detachment increased. Prior QOL predicted three subsequent coping strategies (seeking social support, keeping feelings to self, wishful thinking). Coping strategies were minimally related to subsequent QOL. Coping strategies and QOL are dynamic processes. QOL may predict coping strategies equally or more than vice versa.     

Counterfactual thinking and quality of life among women with silicone breast implants

This study examined the relationship of counterfactual thinking (thoughts about how one's current situation might have turned out differently) with psychosocial adjustment and quality of life in a sample of women with silicone breast implants. Seventy-four women who were concerned about or who were experiencing problems with their implants were recruited following magnetic resonance imaging (MRI) evaluation. Participants completed measures of counterfactual thinking, psychosocial adjustment, and quality of life (QOL). Results indicated that counterfactual thinking was significantly associated with more psychosocial adjustment difficulties, more perceived implant-related health problems, and poorer QOL in the physical health domain. These findings provide additional insight into the factors that may influence adjustment in a complex and poorly understood population and also have implications for understanding the adjustment process to other types of illnesses.     

Predictors of social support and psychological distress in women with breast cancer

This investigation sought to understand previous well-cited and worrisome findings that women treated for breast cancer with breast-conserving surgery compared to mastectomy experience less social support and more mood disturbance, and that social support from significant others erodes over time. Ninety-three women with breast cancer and a subset of their partners completed assessments at the time of surgical treatment and at 3 and 13 months post-treatment. Contrary to the previous findings, type of surgical treatment was not related to perceptions of social support or psychological functioning. Perceptions of social support and psychological distress decreased over time, and the discrepancy between recipients' and providers' judgments of available support increased over time. Low levels of physical functioning led to relative increases in social support, whereas high levels of psychological distress led to relative decreases in social support. Social support as rated by patients (but not their partners) was a significant predictor of changes in psychological distress.     

Psychological adjustment of children with asthma: effects of illness severity and recent stressful life events.

Although children with chronic illness are at greater risk for decreased psychological adjustment than physically healthy children, little is known about the factors that lead to increased risk. Eighty-one children with asthma between the ages of 6 and 14 years and their parents participated in a study to determine the relative contribution of background variables (age, gender, and socioeconomic status), recent stressful life events, and illness severity to psychological adaptation. Overall 11.5% of the children had CBCL Total Behavior Problems scores above the 98th percentile. Multiple regression revealed that lower SES, negative life change, and high illness severity were predictive of less optimal psychological adjustment. The results highlight the need for interventions to improve coping with both disease and nondisease issues.     

Trajectories of depressive symptoms and stressful life events among male and female adolescents in divorced and nondivorced families

This 11-year longitudinal study models the trajectories of depressive symptoms among approximately 550 females and males raised in divorced and nondivorced families in the rural Midwest. Using multilevel analyses, we demonstrate that, first, depressive symptoms changed according to a curvilinear pattern, especially for females; they increased during early to midadolescence and then declined in late adolescence to young adulthood. Second, compared with males, females experienced a greater number of depressive symptoms in adolescence and early adulthood. Third, children who experienced parental divorce by age 15 manifested a sharper increase in depressive symptoms compared to those from nondivorced families. Fourth, stressful life events children experienced shortly after parental divorce mediated the effect of parental divorce on depressive symptoms. Fifth and finally, time-varying stressful life events, particularly those related to relationship and personal loss, were significantly associated with the trajectories of depressive symptoms.

The influence of socioeconomic status and ethnicity on adolescents' exposure to stressful life events

OBJECTIVE: To test the relations between resource-based and prestige-based measures of socioeconomic status (SES), ethnicity, and life events that varied in valence, dependency on adolescent behavior, and duration. METHOD: Six measures of SES were administered to the parents of 148 black and white adolescents, who completed a measure of five mutually exclusive categories of life events. RESULTS: As predicted, our results suggest that having few assets and being black were independently related to life events exposure. Correlations between socioeconomic indices were not so high as to suggest redundancy, and different SES indicators were of importance in predicting exposure to different types of life events.     

5-HTTLPR genotype, stressful life events and late-life depression: no evidence of interaction in a French population

Modification of the effect of life events on risk of depression by a polymorphism in the serotonin transporter gene promoter (5-HTTLPR) has been reported in child, adolescent, adult and elderly populations. Replication attempted on data collected from 1421 individuals aged 65 and over from a French community study provided no evidence of a similar modifying effect. In the only analysis known to the authors to be carried out in an exclusively elderly, European population, this null finding remained consistent after restriction of analysis to prevalent or incident cases.     

Dating concerns among women with breast cancer or with genetic breast cancer susceptibility: a review and meta-synthesis

ABSTRACT

Objective. While dating is critical in the formation of a lifelong romantic relationship, women with breast cancer or a genetic susceptibility to developing this disease report a myriad of dating concerns. This review synthesises and discusses the perceived dating barriers and concerns in this population. Method. A systematic search of CINAHL, Embase, MEDLINE, PsycINFO and PubMed was undertaken and yielded 19 published qualitative studies. Papers were subjected to critical appraisal to ensure the integrity of findings. Results. Six areas of concern were identified: Feeling unattractive due to treatment side effects; perceiving limited dating partners available; determining how, when and what to disclose; fear of cancer recurrence and reduced life expectancy; apprehension about entering into a new sexual relationship; and dating urgency and not wanting to ‘waste time’ on partners without long-term potential. Conclusions. This paper provides a valuable synthesis of the complex issues, concerns and decisions that single women face at different stages of relationship formation following their breast cancer experience. Future research is warranted to explore the perceptions, appraisals and beliefs underlying these concerns, to help guide the future design and development of appropriate informational and supportive care offered to breast cancer patients.     

A longitudinal study of depression, pain, and stress as predictors of sleep disturbance among women with metastatic breast cancer

OBJECTIVE: Sleep disturbances are common among women with breast cancer and can have serious consequences. The present study examined depression, pain, life stress, and participation in group therapy in relation to sleep disturbances in a sample of women with metastatic breast cancer. METHODS: Ninety-three women with metastatic breast cancer participated in a large intervention trial examining the effect of the group therapy on their symptoms. They completed measures of depression, pain, life stress, and sleep disturbance at baseline, 4, 8 and 12 months. RESULTS: The results showed that higher initial levels of depression at baseline predicted problems associated with getting up in the morning, waking up during the night, and daytime sleepiness. Increases in depression over the course of 12 months were associated with fewer hours of sleep, more problems with waking up during the night and more daytime sleepiness. Higher levels of pain at baseline predicted more problems getting to sleep. Increases in pain predicted more difficulty getting to sleep and more problems waking up during the night. Greater life stress at baseline predicted more problems getting to sleep and more daytime sleepiness. CONCLUSIONS: Depression, pain, and life stress scores were each associated with different types of negative change in self-reported sleep disturbances. Depression, especially worsening depression, was associated with the greatest number of types of negative change. The relationships found between sleep disturbance and depression, pain, and life stress suggest specific ways to address the problem of sleep disturbance for women with metastatic breast cancer and show how different types of disturbed sleep may be clinical markers for depression, pain, or life stress in this population.
