Stressful life events, anxiety sensitivity, and internalizing symptoms in adolescents.

Anxiety sensitivity represents a robust risk factor for the development of anxiety symptoms among both adolescents and adults. However, the development of anxiety sensitivity among adolescents remains inadequately understood. In this study, the authors examined the role of stressful life events as a risk factor for the development of elevated anxiety sensitivity. Anxiety sensitivity was then examined in a longitudinal design as a mechanism linking stressful life events to changes in anxiety symptoms. Stressful life events, anxiety sensitivity, and internalizing symptoms were assessed in a diverse community sample of adolescents (N = 1,065) at 3 time points spanning 7 months. The results indicated that stressful life events were longitudinally associated with increases in anxiety sensitivity and that certain types of stressful life events, specifically events related to health and events related to family discord, were differentially predictive of increases in anxiety sensitivity. Moreover, anxiety sensitivity mediated the longitudinal relation between stressful life events and anxiety symptoms. Evidence was also found for the predictive specificity of anxiety sensitivity to symptoms of anxiety but not depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Being popular can be healthy or unhealthy: Stress, social network diversity, and incidence of upper respiratory infection.

Diverse social contacts are generally associated with better health. However, diverse contacts can increase exposure to infectious agents. This should increase risk for disease, particularly among those whose host resistance is otherwise compromised (e.g., stressed individuals). In this prospective study, healthy college students who completed questionnaires assessing social network diversity and stressful life events were subsequently interviewed weekly for 12 weeks to track incidence of upper respiratory infections (URIs). URI episodes were defined by a symptom criterion and by clinically verified self-reported illness. Stress and diversity of social contacts interacted; diversity was associated with more illnesses among those with more stressful life events and slightly fewer illnesses among those with fewer stressful life events. Associations remained after controlling for neuroticism. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of stressors on breast cancer incidence in the Women's Health Initiative.

Objective: To examine associations among life events stress, social support, and breast cancer incidence in a cohort of postmenopausal women. Design and main outcome measure: Women's Health Initiative observational study participants, breast cancer free at entry, who provided assessment of stressful life events, social support, and breast cancer risk factors, were prospectively followed for breast cancer incidence (n = 84,334). Results: During an average of 7.6 years of follow-up, 2,481 invasive breast cancers were diagnosed. In age-adjusted proportional hazards models, 1 stressful life event was associated with increased risk, but risk decreased with each additional stressful life event. After adjustment for confounders the decreasing risk was not significant. Stressful life events and social support appeared to interact in relation to breast cancer risk such that women who had greater number of stressful life events and low social support had a decreased risk of breast cancer. Conclusions: This study found no independent association between stressful life events and breast cancer risk. The results are compatible with a more complex model of psychosocial factors interacting in relation to breast cancer risk. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stress resilience in early marriage: Can practice make perfect?

As all couples experience stressful life events, addressing how couples adapt to stress is imperative for understanding marital development. Drawing from theories of stress inoculation, which suggest that the successful adaptation to moderately stressful events may help individuals develop a resilience to future stress, the current studies examined whether experiences with manageable stressors early in the marriage may serve to make the relationship more resilient to future stress. In Study 1, 61 newlywed couples provided data regarding their stressful life events, relationship resources (i.e., observed problem-solving behaviors), and marital satisfaction at multiple points over 2? years. Results revealed that among spouses displaying more effective problem-solving behaviors, those who experienced moderate stress during the early months of marriage exhibited fewer future stress spillover effects and reported greater increases in felt efficacy than did spouses who had less experience with early stress. Study 2 examined stress resilience following the transition to parenthood in a new sample of 50 newlywed couples. Again, spouses who experienced moderate stress during the early months of marriage and had good initial relationship resources (i.e., observed support behaviors) reported greater marital adjustment following the transition to parenthood than did spouses who had good initial resources but less prior experience coping with stress. Together, results indicate that entering marriage with better relationship resources may not be sufficient to shield marital satisfaction from the detrimental effects of stress; rather, couples may also need practice in using those resources to navigate manageable stressful events.

Life events, fitness, hardiness, and health: A simultaneous analysis of proposed stress-resistance effects.

The effects of exercise participation, self-perceived fitness level, and dispositional hardiness for promoting stress resistance were examined in a sample of 373 college students. Self-report measures of stressful life experience and recent physical illness were positively correlated, and fitness and hardiness were negatively correlated with illness as expected. Multiple regression analyses indicated that neither fitness nor hardiness provided a stress-moderator effect because neither was found to significantly interact with stress in the prediction of illness scores. Structural equation analyses suggested that hardiness may affect health indirectly by first influencing either the occurrence or subjective interpretation of stressful life events. No direct effect on health was found for exercise participation, although exercise may reduce illness indirectly by improving fitness. Implications for the multivariate modeling of proposed stress-resistance-enhancing effects are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relationships among life events, self-derogation, and psychological impairment in psychiatric outpatients.

Investigated relationships among stressful life events, self-derogation, and psychological impairment in 97 community mental health center outpatients to test predicted associations among the 3 variables and a path hypothesis linking life events to impairment via a self-derogatory reaction to life experiences. Results suggest that life events and self-derogation are each associated with impairment but that life events do not affect health–sickness via self-derogation. The possibility of inferring an etiological role for life events and self-derogation in psychopathology is briefly discussed.

Depressed and nondepressed inpatients' cognitions of hypothetical events, experimental tasks, and stressful life events.

40 depressed (mean age 40 yrs) and 30 nondepressed (mean age 38 yrs 3 mo) inpatients' attributions and other cognitions were assessed for 3 types of situations: stressful life events (the Beck Depression Inventory), hypothetical events (Attributional Styles Questionnaire), and experimental (noise-escape) tasks. Depressed Ss manifested a greater depressive attributional style in response to stressful life events but did not differ from nondepressed Ss in their attributions of hypothetical events or experimental tasks. Correlations assessing cross-situational consistency of attributions were largely nonsignificant. Corrections for attenuation and analyses of trained evaluators' ratings of Ss' attributions did not substantially alter the pattern of results.

Are traumatic events necessary to elicit symptoms of posttraumatic stress?

A diagnosis of posttraumatic stress disorder (PTSD) has been conceptualized as being precipitated by a particularly traumatic stressor (e.g., combat exposure, rape, and violent assault). Recent research suggests that common stressful events (e.g., relational problems, divorce, and expected death of a loved one) may also be capable of eliciting posttraumatic symptomatology. The current study replicated and extended these previous findings, examining three groups of event exposure: those who reported experiencing only traumatic events in the past year, those who reported experiencing only significant stressful life events in the last year, and those who experienced both types of events. Consistent with previous findings, we found that all three groups of event exposure, including those experiencing only stressful life events, experienced similar amounts of PTSD symptomatology across symptom clusters. These data add to the growing literature that suggests that the type of events that cause symptoms of PTSD may be broader than the current diagnostic criteria indicate, and as such calls for more rigorous research in this area to better understand the diagnostic implications of these findings.

Perceived social isolation makes me sad: 5-year cross-lagged analyses of loneliness and depressive symptomatology in the Chicago Health, Aging, and Social Relations Study.

We present evidence from a 5-year longitudinal study for the prospective associations between loneliness and depressive symptoms in a population-based, ethnically diverse sample of 229 men and women who were 50–68 years old at study onset. Cross-lagged panel models were used in which the criterion variables were loneliness and depressive symptoms, considered simultaneously. We used variations on this model to evaluate the possible effects of gender, ethnicity, education, physical functioning, medications, social network size, neuroticism, stressful life events, perceived stress, and social support on the observed associations between loneliness and depressive symptoms. Cross-lagged analyses indicated that loneliness predicted subsequent changes in depressive symptomatology, but not vice versa, and that this temporal association was not attributable to demographic variables, objective social isolation, dispositional negativity, stress, or social support. The importance of distinguishing between loneliness and depressive symptoms and the implications for loneliness and depressive symptomatology in older adults are discussed.

The role of childhood abuse and neglect in the sensitization to stressful life events in adolescent depression.

This study examined the role of childhood abuse and neglect in sensitizing adolescents to the effects of proximal stressful life events in a cross-sectional sample of 103 depressed and nondepressed adolescents. Consistent with hypotheses, adolescents with a history of childhood abuse and/or neglect reported a lower level of threat of stressful life events prior to episode onset than that reported by those without. This effect was specific to those on their 1st episode of depression and was specific to independent events (i.e., stressors outside of adolescents' control). Further, this effect was robust when controlling for level of chronic difficulties, which was higher in those with childhood abuse and/or neglect. The authors suggest that childhood abuse and/or neglect may be an important risk factor that sensitizes individuals to the effects of acute independent life events.

Impact of psychological and physical health, stressful events, and social support on subsequent mental health help seeking among older adults.

Factors that influence mental health help seeking among adults 55+ yrs were examined prospectively. A discriminant analysis significantly differentiated between 120 older adults needing and seeking services and a comparison group of 120 older adults not needing services. Prior to having sought help, help seekers demonstrated poorer psychological well-being, reported more physical health problems, reported a higher level of unpleasant stressful events, and perceived greater deficits in the amount of social support available to them in time of need. The vast majority of these older help seekers sought help for their mental health problems from a medical doctor rather than from a mental health center or clinic or from a minister. Significantly more help seekers than nonseekers experienced stressful events involving bereavement, social and economic loss, and new physical illness.

Negative life events, perceived stress, negative affect, and susceptibility to the common cold.

After completing questionnaires assessing stressful life events, perceived stress, and negative affect, 394 healthy Ss were intentionally exposed to a common cold virus, quarantined, and monitored for the development of biologically verified clinical illness. Consistent with the hypothesis that psychological stress increases susceptibility to infectious agents, higher scores on each of the 3 stress scales were associated with greater risk of developing a cold. However, the relation between stressful life events and illness was mediated by a different biologic process than were relations between perceived stress and illness and negative affect and illness. That these scales have independent relations with illness and that these relations are mediated by different processes challenges the assumption that perceptions of stress and negative affect are necessary for stressful life events to influence disease risk.

Do stressful life events affect duration of gestation and risk of preterm delivery?

The present study was designed to test the relation between stressful life events experienced during pregnancy and the risk of preterm delivery and shortened duration of pregnancy. We collected data prospectively in a general population sample, including repeated questionnaire measures of exposure to stressful life events during pregnancy. Between August 1989 and September 1991, 8,719 Danish-speaking women with singleton pregnancies attended antenatal care. Of these women, 5,873 (67%) completed all questionnaires. When indicating an event, the woman was asked to rate the amount of stress induced by this event. Measurement of gestational duration was primarily based on early ultrasound scan. When we evaluated life events independently of the individual's appraisal, we found no association with duration of gestation or risk of preterm delivery. In contrast, life events assessed by the subject as highly stressful were associated with shorter mean duration of gestation and increased risk of preterm delivery. This association was observed primarily with events experienced between the 16th and 30th week of gestation. Women who had one or more highly stressful life events had a risk of preterm delivery 1.76 times greater than those without stressful events (95% confidence interval = 1.15-2.71). We found no evidence for a buffering effect of social support.     

Exercise as a buffer of life stress: A prospective study of adolescent health.

Investigated stress and well-being in adolescence to examine the ability of exercise to buffer stress-induced deteriorations in physical health. 384 female 7th–8th graders completed a life events survey, the Seriousness of Illness Rating Scale, and an activity questionnaire at the beginning and end of the academic year. Analyses revealed that the negative impact of stressful life events on health declined as exercise levels increased. Findings suggest that exercise may be a valuable resource for combating life stress. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stressful life events, social support, and mortality in men born in 1933

OBJECTIVE: To examine relations between stressful life events and mortality in middle aged men. DESIGN: Prospective population study. Data on stressful life events, social network, occupation, and other psychosocial factors derived from self administered questionnaires. Mortality data obtained from official registers. SETTING: City of Gothenburg, Sweden. SUBJECTS: 752 men from a random population sample of 1016 men aged 50. MAIN OUTCOME MEASURE: Mortality from all causes during seven years' follow up. RESULTS: Life events which had occurred in the year before the baseline examination were significantly associated with mortality from all causes during seven years' follow up. Of the men who had experienced three or more events during the past year 10.9% had died compared with 3.3% among those with no life events (odds ratio 3.6; 95% confidence interval 1.5 to 8.5). The association between recent life events and mortality remained true after smoking, self perceived health, occupational class, and indices of social support were controlled for. Many of the deaths were alcohol related, but the number of deaths was too small to allow for analyses of specific causes of death. The association between life events and mortality was evident only in men with low emotional support. CONCLUSION: Stressful life events are associated with high mortality in middle aged men. Men with adequate emotional support seem to be protected.     

Students' stress, coping strategies, and school completion: A longitudinal perspective.

This study investigated the relationship between two intrapersonal variables-- stressful life change events and reported coping strategies-- and high school completion status among early adolescents. The sample was comprised of 92 students (44 females and 48 males) who had completed questionnaires regarding the number and types of life change events they had experienced and the coping strategies they reported using during ninth grade. A 3-year follow-up study of these students was completed to determine whether they finished high school or reported dropping out. Discriminant analysis was used to build a prediction model and indicated that the coping factors of Social Activities and Seeking Professional Support significantly predicted high school dropout status, whereas Family Involvement was negatively related to this outcome. These findings are discussed in light of current research, and suggestions for future research are provided. Interventions that focus on the contextual variables related to family and peers are indicated, as is the need for school psychologists and other school mental health professionals to offer coping skills training.

Stress reactivity following brief treatment for depression: Differential effects of psychotherapy and medication.

Psychotherapy and medication treatments are both effective in reducing depressive symptoms. However, only psychotherapy provides an enduring effect by reducing depressive vulnerability following treatment termination. This differential efficacy may reflect mode-specific effects on the longitudinal relationship between depression and stress. The current study examined posttreatment data from 153 outpatients enrolled in the Treatment of Depression Collaborative Research Program. Longitudinal analyses using the latent difference score (LDS) framework (a structural modeling technique that combines features of latent growth curve and cross-lagged regression models) evaluated the temporal relationship between severity of depression and frequency of stressful life events, assessed by interviewers at treatment termination and at 6, 12, and 18 months following treatment. Results supported a stress reactivity model in that stressful events led to elevations in the rate of depression change. Furthermore, multigroup LDS analysis indicated that this longitudinal stress reactivity occurred only for outpatients in the medication conditions. Results demonstrate that the enduring impact of psychotherapy involves the development of enhanced resiliency to stressful life events.

Maternal mood, video-mediated cognitions, and daily stress during home-based, family interactions.

This article presents an in vivo investigation of maternal negative mood, maternal video-mediated cognitions, and daily stressors in families with young children. Specifically, it was hypothesized that greater levels of maternal depressed, anxious, and hostile mood states immediately prior to a daily, reportedly routine, stressful parent–child interaction would be significantly associated with higher percentages of dysfunctional and lower percentages of functional cognitions. Forty-five mothers of 2- to 5-year-old children participated in this study by rating their mood before being videotaped in a daily routine with their child they reported as recurrent and stressful (e.g., mealtime). Using video-mediated recall (VMR) methodology, mothers were instructed to recall their cognitions upon immediate video review. Results indicated that greater levels of negative mood were associated with a greater percentage of dysfunctional cognitions and a smaller percentage of functional cognitions. Levels of maternal depressed mood were significantly and independently associated with greater rates of dysfunctional and lower rates of functional cognitions. Negative mood states were not consistently associated with the amount of maternal self-reported general irrationality, pointing to the utility of the VMR to elicit maternal cognitions specific to the observed interaction, which may have more implications for clinical intervention than more general irrationality measures. Evaluating maternal mood and using video-mediated maternal cognitions regarding daily family stressors can precipitate clinical interventions meant to reduce family-related stress and potentially improve maternal and child mental health outcomes.

Stress, social support, and distress in a statewide population of persons with AIDS in New Jersey

This study examined the effects of stress, social support, and health status on distress in a sample of 79 persons with AIDS in New Jersey. The study used New Jersey's AIDS Registry as a geographically based list sampling frame, with data gathered through in-person interviews. The study examined the effects of health status (operationalized as symptom burden), stress (operationalized with a stressful-life-events scale), social support from friends, and social support from family on depression as measured by the Center for Epidemiological Studies-Depression (CES-D) scale. We examined the differential effects of friend support and of family support at differing levels of stressful life events. Results indicate that health status and stressful life events both have substantial impact on distress. Friend support reduced distress under lower-stress conditions, while family support reduced distress under high-stress conditions. These results suggest that social support from peers is critical for emotional well-being of persons with HIV in many circumstances, but that in periods of crisis family support becomes a more important determinant of emotional well-being.     

Trait reappraisal amplifies subjective defeat, sadness, and negative affect in response to failure versus success in nonclinical and psychosis populations.

Perceptions of defeat have been linked to a range of clinical disorders including psychosis. Perceived defeat sometimes increases in response to failure, but the strength of this association varies between individuals. The present research investigated whether trait reappraisal, a thought-focused coping style, amplified response to stressful events. Two studies (Study 1, n = 120 nonclinical participants; Study 2, n = 77 participants with schizophrenia-spectrum disorders) investigated whether trait reappraisal amplified feelings of defeat following an experience of failure versus success. Frequent reappraisers showed the largest increases in subjective defeat after failure versus success in both studies, with nonclinical participants with greater habitual reappraisal also showing larger increases in sadness and general negative affect. Frequent use of reappraisal may confer vulnerability to subjective defeat in response to stressful life events among nonclinical and clinical populations and could be an area for relapse prevention interventions to target.
