Number Of Stressful Life Events Research Articles

Predictors and correlates of continuing involvement with the baby's father among adolescent mothers.

Predictors and correlates of a stable ongoing relationship with the baby's father among adolescent mothers were examined. A longitudinal study was conducted of 105 adolescent mothers and their infants over an 18- to 24-month period. Fathers were more likely to stay involved with the adolescent mother if the couple had an intimate and supportive relationship 6 weeks after delivery. They were less likely to stay involved if the young mother experienced a large number of stressful life events during pregnancy and in the first 6 weeks after delivery. Among adolescent mothers who remained in a stable relationship with the baby's biological father, higher scores were obtained on the Home Observation for Measurement of the Environment (B. M. Caldwell & R. H. Bradley, 1984), the young mothers were more likely to report continuous custody of their infants, and the infants' physicians were less likely to report infant injuries, accidents, or investigations of child abuse or neglect.

Laughter and stress in daily life: Relation to positive and negative affect.

The present study investigated the proposal that increased laughter can serve to moderate the affective impact of negative life events. Community participants kept a record of their actual frequency of laughter for a 3-day period, and completed a measure of stressful life events each evening. Current levels of positive and negative affect were also obtained in the morning and evening of each day. A series of simple correlations, computed on a daily basis, provided little evidence for any direct relationships between amount of daily laughter and either positive or negative affect. Instead, more complex moderator analyses revealed that greater negative affect was clearly associated with a higher number of stressful life events, but only for those individuals with a lower frequency of actual laughter. In contrast, and in support of a stress buffering hypothesis, it was found that individuals with a higher frequency of laughter did not show greater levels of negative affect as stressful life events increased. When considering positive affect, it was found that only males showed a significant moderating effect of laughter. For males who laughed more frequently, a greater number of stressful life events was associated with higher levels of positive affect. These findings are discussed in terms of several possible mechanisms which may account for the moderating effects of laughter on affect, including the use of cognitive appraisals and emotion-focused coping strategies.

Stressful life events and depressive symptoms among the elderly. Evidence from a prospective community study.

We examined the effect of a series of common stressful life events on change in depressive symptoms among the elderly. The subjects were 1,962 noninstitutionalized people 65 years of age or older from the New Haven EPESE project. Multivariate regression models revealed that 8 of 11 stressful life events examined predicted change in depressive symptoms at follow-up (1985) after controlling for baseline depressive symptoms age, socioeconomic factors, functional status, and chronic conditions. In addition, the total number of stressful life events was significantly associated with higher CES-D depression scores. A dose-response relationship between cumulative life event stress and change in depressive symptoms was also shown. These results suggest that certain common life event stressors may have an impact on mental health, both singly and in combination.

Partners' stress underestimations lead to women's distress: a study of pregnant inner-city women.

The authors examined how men's underestimation of the stress that their pregnant female partners reported influenced women's psychological distress and their sense that they were not supported. Participants included 68 pregnant inner-city women and their partners, among whom African Americans and European Americans were represented. Women who reported a greater number of stressful life events had increased depression if their partners did not report them as encountering these events. However, if their partners reported them as encountering a high number of stressful events, the otherwise negative impact of stress was buffered. Partners' stress report had no appreciable effect when women reported a low number of stressful events. This partner underestimation effect was independent of the influence of women's report of social support.

Children of psychosocial risk-mothers: life events, social interaction, and behaviour problems at the age of 8 years.

The number of stressful life events experienced as measured on the modified Swedish version of Coddington's questionnaire, and the presence of behaviour problems assessed by Achenbach's Child Behavior Check List (CBCL) were studied in 45 eight-year-old children of identified psychosocial risk-mothers. The mothers' social network was estimated using the Swedish version of Undén and Orth-Gomér's Interview Schedule for Social Interaction (ISSI). These mothers had been identified during early pregnancy. A control group of 57 children of the same age and their mothers without the presence of psychosocial risk-criteria was used as reference. The results indicated that the index children had experienced significantly more life events, and displayed significantly more behaviour problems than the reference children. The mothers in the index group had a significantly poorer social network than the mothers in the reference group. The study suggests that children of mothers, identified early on psychosocial risk criteria develop suboptimally. Therefore, early interventions are of great importance.

Self-reported stress and risk of breast cancer.

Many women attribute the development of their breast cancer to psychosocial factors such as stress and depression. Yet investigations of the relationship between breast cancer and stressful life events have had inconsistent outcomes, due in part to studies with small sample sizes and reliance on hospital-based populations. As part of a population-based, case-control study of breast cancer etiology, we evaluated the association between stressful life events and the risk of breast cancer among 258 breast cancer patients and 614 randomly selected population-based controls. Information on 11 stressful life events was collected in telephone interviews with women aged 50-79 who were participating in the ongoing study. Breast cancer patients and controls experienced the same number of stressful life events in the five years prior to diagnosis or an equivalent reference date (controls), averaging 2.4 and 2.6 events, respectively. After adjustment for known breast cancer risk factors, there was no association between weighted stressful life event scores and the risk of breast cancer (odds ratio [OR] = 0.90 per unit increase; 95% confidence interval [CI], 0.78-1.05). Only one life event, death of a close friend, was significantly more often reported by controls (OR = 0.72; 95% CI, 0.52-1.00). Other life events were inconsistently and nonsignificantly associated with breast cancer risk. CONCLUSIONS. The results of this retrospective study do not suggest any important associations between stressful life events and breast cancer risk.

Aggression, depression, and stressful life events predicting peer rejection in children

AbstractThis short-term prospective study examined the contribution of aggression and depression, stressful life events, and their interactions to the prediction of peer rejection. Subjects were 497 fifth- and sixth-grade children who completed questionnaires at two time points separated by approximately 3 months. Levels of peer rejection and aggression were assessed by peer nominations; level of depressive symptoms and number of stressful life events were measured by self-report questionnaires. Controlling for sex and baseline level of peer rejection, aggression directly predicted peer rejection. In contrast, depressive symptoms interacted with life stress to predict peer rejection. Examination of the Depression × Stress interaction revealed that depressive symptoms in children who had experienced high levels of life stress were not associated with increased levels of peer rejection, whereas depressive symptoms in children with low levels of stress were predictive of subsequent peer rejection. Several interpretations of these findings and directions for future research are suggested.

Social skill in third and sixth grade children: A moderator of lifetime stressful life events and behavior problems?

We investigated relationships among stressful lifetime life events, social skill, and behavior problems in children. Participants were 159 third graders, 138 sixth graders, and their mothers. Mothers reported on their children's life events, social skill, and behavior problems. Children self-reported on their social skill and behavior problems. Increased numbers of stressful life events significantly predicted increased behavior problems in third and sixth graders. Increased social skill significantly predicted decreased behavior problems in third and sixth graders. Social skill served a stress-protective role for third but not sixth graders; third graders with increased life events and better social skill had fewer behavior problems than their less socially skilled peers. Practical and theoretical implications are discussed, and suggestions for future resilience research are presented.

Non‐genetic risk determinants for type 1 (insulin‐dependent) diabetes mellitus in childhood

Using the prospective Hungarian childhood diabetes register, a nationwide case-control study was carried out to investigate the possible role of various non-genetic factors as risk determinants for type 1 diabetes in childhood. A questionnaire (covering family characteristics, social status, fetal and perinatal events, breast-feeding habits, infectious diseases and stressful life events) was sent by mail to all incident diabetic children in 1990 (n = 163) and to two referent children (for each diabetic child), matched for age, sex and county. Diabetic children had a tendency to have mothers > 35 years of age (odds ratio (OR) = 3.52; 95% confidence intervals (CI) 0.74-16.79), a lower proportion of their mothers had higher education (OR = 1.69; 95% CI 0.95-3.0) and these children tended to move home more frequently (OR = 1.99; 95% CI 0.97-4.1). Although the duration of exclusive breast feeding was similar in both groups, the proportion of diabetic children who received no breast milk tended to be higher (OR = 1.76; 95% CI 0.91-3.4). A higher proportion of diabetic children reported non-specific infections (OR = 2.94; 95% CI 1.19-7.21) and the number of stressful life events was higher in diabetic children aged 10-14 years (OR = 3.9; 95% CI 1.14-13.27). As the risk determinants for childhood insulin-dependent diabetes mellitus identified in our low-risk population appear to be similar to those detected in the genetically different, high-risk Swedish population, our study strongly supports an etiological role for these non-genetic risk factors in IDDM.

Life-Span Adjustment of Children to Their Parents' Divorce

Children who experience parental divorce, compared with children in intact two-parent families, exhibit more conduct problems, more symptoms of psychological maladjustment, lower academic achievement, more social difficulties, and poorer self-concepts. Similarly, adults who experienced parental divorce as children, compared with adults raised in continuously intact two-parent families, score lower on a variety of indicators of psychological, interpersonal, and socioeconomic well-being. However, the overall group differences between offspring from divorced and intact families are small, with considerable diversity existing in children's reactions to divorce. Children's adjustment to divorce depends on several factors, including the amount and quality of contact with noncustodial parents, the custodial parents' psychological adjustment and parenting skills, the level of interparental conflict that precedes and follows divorce, the degree of economic hardship to which children are exposed, and the number of stressful life events that accompany and follow divorce. These factors can be used as guides to assess the probable impact of various legal and therapeutic interventions to improve the well-being of children of divorce.

Psychosocial factors in the development and progression of breast cancer.

The factors responsible for the genesis of breast cancer remain unclear. Emerging, although controversial, evidence suggests that factors related to life-style, such as dietary fat or alcohol intake, or exposure to various forms of stressors, are associated with mammary tumorigenesis. The possible role of life-style factors in breast cancer is important in light of the fact that mortality to this disease is increasing in most countries and that development of curative therapies for breast cancer has not been forthcoming. Thus, determining the role of life-style factors in the onset and progression of breast cancer, particularly among individuals genetically vulnerable to breast cancer or women with breast cancer in remission, is critical to prevent this disease. We will review the three main hypotheses which have been suggested to link psychosocial factors to the etiology of cancer, emphasizing data obtained through animal models. Interpretation of the existing data suggests that the number of stressful life-events does not predict vulnerability to develop breast cancer or survival from it; a certain level of stress appears to protect from malignancies. The crucial factor affecting tumor growth is the interaction among stress, an individual's personality, and available psychosocial support, and the effect of this interaction on an individual's ability to cope with stress. In addition, other risk factors for breast cancer known to be closely associated with psychosocial factors, namely dietary fat and alcohol consumption, may interact with the effects of psychosocial factors on breast cancer.

Relationship of child sexual abuse to depression

Thirty-nine girls aged 6 to 12 participated in this study, each having been referred for evaluation of suspected child sexual abuse. The study investigated the prevalence of depression in the sample as well as the relationship of depressive symptoms to severity of abuse and potential mediator variables. The Child Behaviour Checklist and Child Depression Inventory were used to assess the severity of depression. A composite score for severity of abuse was derived from child disclosure and medical findings. Results indicated that 67% of the children could be classified as experiencing symptoms consistent with a diagnosis of depression. Severity of abuse was not significantly correlated with depression intensity scores. Stepwise regression analyses revealed that a high number of stressful life events and low IQ were significant predictors of depression scores. The clinical implications of these findings are discussed.

Predicting psychiatric symptoms among homeless people.

Multiple regression was used to predict psychiatric symptoms among homeless people. The following variables were significant predictors of psychiatric symptoms: current life satisfaction, previous psychiatric hospitalization, the number of stressful life events, social support, problem drinking, and childhood unhappiness. The results are discussed in terms of their policy and practice implications, particularly the need for crisis intervention services and for dual-diagnosed clients.

‘University Blues’: Depression among Tertiary Students during an Academic Year

Abstract Depression levels of 148 undergraduates were measured at the beginning and the end of an academic year: 16% were depressed initially; 18% were depressed at the end of the year; 73% were not depressed on either occasion; 7% were depressed on both occasions. The major predictor of students' end-of-year depression levels was initial depression level. Students' scores on an irrational beliefs test and the number of stressful life events experienced were also predictive of end-of-year depression.

Child maltreatment, stressful life events, and behavior problems in school-aged children in residential treatment.

This study examined the prevalence of child maltreatment, stressful life events, and behavior problems in school-aged children in residential treatment. The sample included 44 children, ages 5-13 years; 61% were male and 39% female. Results indicated that the entire sample had experienced one or more types of maltreatment, with physical abuse being more prevalent. Seventy-four percent of subjects scored in the clinical range on the Child Behavior Checklist (Achenbach & Edelbrock, 1983). Proportionally more physically abused children scored in the clinical range when compared to nonphysically abused children. The number of stressful life events experienced after admission to the treatment facility was found to be related to increased behavior problems.

Stress in Parents and Late Elementary Age Children in Divorced and Intact Families and Child Adjustment

The cumulative effect of stressful life events on 40 children in the 4th to 6th grades who were in matched pairs from intact and divorced families were investigated. Children's adjustment was assessed by parent report, teacher report and fantasy material from an abbreviated Thematic Apperception Test. In comparison to children from intact families, children of divorce were rates as less well adjusted by parents and teachers (as expected), and they had a greater number of rejection themes in fantasy. There was no interaction between stress levels and marital status in predicting child adjustment. Higher parental stress was related to parent ratings of internalizing and externalizing symptoms in the child, and to teacher rated externalizing symptoms in the child. Higher numbers of stressful life events that were primarily child oriented were related to higher teacher ratins of anxiety, social withdrawal and internalizing symptoms. Thus, the source of stress leads to different types of maladjustment.

Psychosocial Predictors of Psychopathology in Epilepsy

The 30-item version of the GHQ was administered to 102 adults with epilepsy, and four sets of variables (neurological, psychosocial, medication, demographic) were used to predict psychiatric distress. Psychopathology was found to be associated with increased perceived stigma, elevated number of stressful life events during the past year, poor adjustment to epilepsy, financial stress, vocational problems, external locus of control, and an earlier onset of epilepsy. Multiple regression procedures reduced this list to three independent predictors of psychopathology: an increased number of stressful life events in the past year, poor adjustment to epilepsy, and financial stress.

Early life events as discriminators of socialized and undersocialized delinquents.

The relationship between early life events and the socialized and undersocialized dimensions of conduct disorder was investigated. Subjects were 40 incarcerated male delinquents and their mothers. The mothers were administered the Children's Life Events Questionnaire and the Developmental Questionnaire. Youths were administered the Adolescent Parent Relations Scale. The results indicated that the undersocialized delinquents had a greater number of stressful life events during their first 4 years of life than did the socialized delinquents. Discriminant function analysis indicated that stressful life events during the 2nd and 4th years were the most important predictors of membership in the undersocialized group. The discriminant function generated was able to classify 82.5% of the sample correctly. The remaining variables did not significantly discriminate the groups.

A Sickly‐Sweet Harvest: Farmworker Diabetes and Social Equality

Type II diabetes mellitus (NIDDM) is used as a model in examining neuroendocrine and experiential linkages between social inequality and health outcome. Ethnographic, psychosocial, and biochemical data collected among Mexican‐American migrant farmworkers reveal that diabetic workers spent more years in migrant labor (p < .01), and reported a greater number of stressful life events (p < .001), than nondiabetics. Body mass index (BMI) did not differ significantly between the two groups. Dopamine‐beta‐hydroxylase, a regulating enzyme in the stress‐responsive catecholamine system, may contribute to diabetes risk for some individuals; other pathways for neuroendocrine mediation of psychosocial stress are discussed. It is proposed that the oppressive life conditions of migrant farmworkers contribute to adverse health outcomes through specific physiological responses to life experiences.

Effects of aerobic exercise training and relaxation training on cardiovascular activity during psychological stress

Students who reported experiencing a high number of stressful life events were randomly assigned to: (a) an aerobic training condition, (b) a relaxation training condition, or (c) a no treatment control condition. Immediately before and after the 11 week training/control period, subjects' aerobic fitness and cardiovascular responses to acute psychological stress were assessed. Results indicated that: (1) subjects in the aerobic training condition showed significantly greater improvements in aerobic fitness than subjects in the other conditions, and (2) the subjects in the aerobic training condition showed significantly greater reductions in heart rate during all phases of the stress than subjects in the other conditions. Post-training differences between aerobic and control conditions during the moderate psychological stress were as great as 17 b.p.m. These results provide evidence for the utility of aerobic training for reducing cardiovascular activity during psychological stress, and they are consistent with earlier findings linking fitness to less illness following stress, reductions in depression and enhanced recovery in cardiac patients.
