Death or illness of a family member,violence, interpersonal conflict,and financial difficulties as predictors of sickness absence: longitudinal cohort study on psychological and behavioral links

OBJECTIVE: Although an association between stressful life events and health problems has been demonstrated, the underlying mechanisms have remained unclear. We examined whether psychological problems and health-risk behaviors underpin the health effects of different event categories. METHOD: The initially healthy participants were 2991 (796 men, 2195 women) municipal employees who had taken no sick leave in 1995. In 1997, they completed a questionnaire requesting information on recent life events and psychological and behavioral factors. The outcome was recorded sickness absences in 1998. RESULTS: In men, the death or serious illness of a family member, violence, and financial difficulties increased the risk of later sickness absence. According to structural equation modeling, violence and financial difficulties also induced psychological problems such as anxiety, mental distress, and lowered sense of coherence. Psychological problems were associated with heightened cigarette and alcohol consumption, which in turn increased sickness absence. A corresponding structural model did not fit the data in relation to death or serious illness of a family member. In women, life events were associated with psychological problems and smoking but not sickness absence. CONCLUSIONS: Longitudinal evidence suggests that increased psychological problems and behaviors involving risk to health partially mediate the effect of stressful life events on health, as indicated by sickness absence. This model received support among men and for the event categories of violence and financial difficulties. Women were less affected by stressful life events than men.     

Risk factors and life processes associated with the onset of suicidal behaviour during adolescence and early adulthood

BACKGROUND: This study examined associations between childhood circumstances, adolescent mental health and life events, and the development of suicidal behaviour in young people aged between 15 and 21 years. METHOD: Data were gathered over the course of a 21-year longitudinal study of a birth cohort of 1265 children born in New Zealand. The measures collected included: (1) patterns of suicidal behaviour (ideation, attempt) (15-21 years); (2) social background, family functioning, parental and individual adjustment during childhood (0-16 years); and (3) time dynamics of mental health and stressful life events during adolescence and early adulthood (15-21 years). RESULTS: By the age of 21 years, 28.8% of the sample reported having thought about killing themselves and 7.5% reported having made a suicide attempt. The childhood profile of those at greatest risk of suicidal behaviour was that of a young person reared in a family environment characterized by socio-economic adversity, marital disruption, poor parent-child attachment and exposure to sexual abuse, and who as a young adolescent showed high rates of neuroticism and novelty seeking. With the exception of the socio-economic and personality measures, the effects of childhood factors were largely mediated by mental health problems and exposure to stressful life events during adolescence and early adulthood. Mental health problems including depression, anxiety disorders, substance use disorder, and to some extent conduct disorder, in addition to exposure to adverse life events, were significantly associated with the onset of suicidal behaviours. CONCLUSIONS: Findings support a life course model of the aetiology of suicidal behaviour in which risk of developing suicidal behaviour depends on accumulative exposure to a series of social, family, personality and mental health factors.     

Risk factors for emotional/behavioral problems in young adolescents: a prospective analysis of adolescent and parental stress and symptoms

Stressful events in the lives of 309 10- to 15-year-olds and stressful events and psychological symptoms reported by their parents were examined in a 9-month study. Ss' self-reported emotional/behavioral problems were predicted by their reports of stressful events and their fathers' reports of psychological symptoms in cross-sectional analyses. Analyses at follow-up after controlling for initial reports of emotional/behavioral problems and prospective analyses predicting from first assessment to follow-up yielded significant effects for Ss' self-reported stressful events. Mothers' reports of children's problems were predicted by mothers' psychological symptoms in cross-sectional analyses and at follow-up after controlling for initial emotional/behavioral problems. Only prior levels of maternal reports of emotional/behavioral problems predicted mothers' reports of their children's problems 9 months later.     

Childhood chronic illness as a family stressor.

Investigated the impact of childhood chronic illness within a family context. We interviewed 30 mothers of 6- to 14-year-old children with asthma or diabetes and 30 mothers of healthy children of the same age and sex. Family functioning, extrafamilial social support available to mothers, and child life stress events were examined in relation to the children's psychological adjustment and illness events. The mothers of asthmatic children reported a greater number of internalizing behavior problems in their children, perceived their own social support as less adequate, and reported a greater number of stressful events. Regression analyses demonstrated that family functioning, maternal social support, and chronic illness were significantly related to the psychological adjustment of the child. The importance of family functioning and resources available to the family, such as social support, are discussed as protective influences in coping with childhood chronic illness.     

Gene–environment interactions in panic disorder and CO2 sensitivity: Effects of events occurring early in life

Heterogeneous life events (LE) precede the onset of—and potentially increase the susceptibility to—panic disorder (PD). It remains unknown whether LE can act as moderators in the context of gene‐by‐environment interactions (G×E) that alter the susceptibility to PD and the related trait of CO₂ sensitivity, nor it is known whether such moderation may depend on occurrence of events at different epochs in life. In 712 general population twins we analyzed by Maximum Likelihood analyses of ordinal data whether life (major‐ and stressful) events moderate the genetic risk for PD and CO₂ sensitivity, as indexed by the 35% CO₂/65% O₂ challenge. For CO₂ sensitivity, best‐fitting models encompassed both additive and interactional effects that increased linearly with the cumulative number and severity (SEV) of events in lifetime. By analyzing the moderation effect of cumulative SEV separately for events that had occurred in adulthood (between age 18 and 37) or during childhood–adolescence (before the 18th birthday), we found evidence of G×E only within the childhood–adolescence window of risk, although twins had rated the childhood–adolescence events as significantly (P = 0.001) less severe than those having occurred during adulthood. For PD, all interactional terms could be dropped without significant worsening of the models' fit. Consistently with a diathesis‐stress model, LE appear to act as moderators of the genetic variance for CO₂ sensitivity. Childhood–adolescence appears to constitute a sensitive period to the action of events that concur to alter the susceptibility to this panic‐related trait. © 2010 Wiley‐Liss, Inc.     

Childhood adversity, recent life events and depression in late life

BACKGROUND: The study investigates whether persons who have experienced childhood adversity are more likely to develop depressive symptoms when faced with recent events. METHOD: Data were used from a population-based sample, aged 55 to 85 years (n=1887), which were not depressed at baseline. Childhood adversities and recent stressful life events were retrospectively assessed. Depressive symptoms were measured with the CES-D. RESULTS: 14.4% of our sample experienced adverse events during childhood (<18 yrs) and 35.4% experienced recent events. Associations of depressive symptoms were found with both, childhood adversity (OR 1.80, 95% CI 1.21-2.69) and recent life events (OR 1.42, 95% CI 1.01-2.00). The effect of recent events on depressive symptoms was not modified by childhood adversity. LIMITATIONS: Underreporting may be present due to unwillingness to report embarrassing events or to disclose painful memories. CONCLUSIONS: No evidence was found for the assumption that older persons were more vulnerable for depression in reaction to recent life events when they were exposed to childhood adversity.     

Stressful life events and skin diseases: disentangling evidence from myth

The possibility of a causal influence of emotional stress, especially of stressful life events, on the course of various skin diseases has long been postulated. Clinical wisdom and experience, as well as many anecdotal observations and uncontrolled case series, support this opinion. We reviewed the available evidence on the role of stressful life events in triggering or exacerbating skin diseases. The role of stressful events in vitiligo, lichen planus, acne, pemphigus and seborrhoeic dermatitis was either controversial or insufficiently explored. The role of stressful events in psoriasis, alopecia areata, atopic dermatitis and urticaria was apparently clearer. However, only a few studies met acceptable methodological standards for stress measurement. Also, few studies considered common potential confounding factors (e.g. age, duration of illness, familial factors), and no study controlled adequately for the influence of other crucial factors (e.g. discontinuation of treatment, seasonal effects). Adding that the large majority of studies were retrospective, it seems wise to conclude that only preliminary evidence has been published so far on the role of stressful life events in bringing on or worsening any dermatological disease. Further research is mandatory, either in the form of prospective studies or, more feasibly, of well-designed case-control studies with adequate statistical power. Future studies should also pay more attention to protective as well as vulnerability factors in stressful events. Further, it would be important to investigate other sources of psychological stress, such as chronic stress and everyday stress. Measuring stress appraisal, although difficult, would also be important.     

Stressful life events and depressive problems in early adolescent boys and girls: the influence of parental depression, temperament and family environment

BACKGROUND: Stressful life events increase the probability of depressive problems in early adolescence. Several genetic and environmental risk factors may change individual sensitivity to the depressogenic effect of these events. We examined modification by parental depression and gender, and mediation of the former by temperament and family environment. METHODS: Data were collected as part of a longitudinal cohort study of (pre)adolescents (n = 2127). During the first assessment wave at approximately age 11, we assessed parental depression, family functioning, perceived parenting behaviours, and temperamental frustration and fearfulness. At the second wave, about two and a half years later, stressful life events between the first and second assessment were assessed. Depressive problems were measured at both waves. RESULTS: Adolescents with parents who had a (lifetime) depressive episode were more sensitive to the depressogenic effect of stressful events than adolescents without depressed parents. Furthermore, girls are more sensitive to these effects than boys. The modifying effect of parental depression was not mediated by temperament, family functioning and perceived parenting. LIMITATIONS: Life events were assessed without consideration of contextual information. Depressive problems were measured by questionnaires that did not directly represent DSM-IV criteria. The measure of parental depression was unspecific regarding severity and timing of depressive episodes. CONCLUSION: The results suggest that gender and parental depression are associated with increased sensitivity to depression after experiencing stressful life events during adolescence.     

Life events, locus of control, and behavioral problems among Chinese adolescents

This study examined associations of life events and locus of control with behavioral problems among 1,365 Chinese adolescents by using the Youth Self-Report (YSR), Adolescent Self-Rating Life Events Checklist (ASLEC), and the Nowicki-Strickland Locus of Control Scale for Children. Results indicated that the overall prevalence of behavioral and emotional problems was 10.7% (95% CI = 9.9-11.5%). Logistic-regression analyses showed that a total of 13 negative life events mainly coming from academic domain and interpersonal relationships, high life-stress score, and high external locus score significantly increased the risk for behavioral problems. Life stress and locus of control significantly interacted with behavioral problems. These findings support the linkage between stressful life events and psychopathology in a general population of adolescents from mainland China, and demonstrate the stress-moderating effects of locus of control on psychopathology as well.     

Predictors of psychological well-being in a diverse sample of HIV-positive patients receiving highly active antiretroviral therapy

The purpose of the present study was to identify variables relevant to psychological well-being in HIV patients receiving highly active antiretroviral therapy (HAART). Multiple stressors accompany living with HIV while managing a HAART regimen. However, a variety of cognitive and behavioral variables can protect against or augment the deleterious effects of stress in this population. The authors hypothesized that satisfaction with social support, coping styles, and maladaptive attributions about HIV would explain more variance in psychological well-being than stressful life events per se. Participants were individuals with HIV receiving antiretroviral therapy-either starting a new HAART regimen or having difficulties adhering to their current regimen. Satisfaction with social support, coping styles, and punishment beliefs about HIV were uniquely associated with depression, quality of life, and self-esteem over and above the effects of stressful life events. These results provide support for continued psychosocial interventions that target these variables among patients with HIV.     

Associations among migration risk factors,cultural identity conflict,and psychological symptoms among Syrian emerging adults with refugee backgrounds in the Netherlands

Objectives

In the present study, we examined relations between premigration, perimigration, and postmigration risk factors (i.e., potentially traumatic events [PTEs], postmigration living problems [PMLPs], stressful life events) and psychological symptoms (i.e., anxiety/depression, posttraumatic stress) in Syrian emerging adults with refugee backgrounds; we also tested cultural identity conflict as a possible mediator of these relations. We expected that greater exposure to migration risk factors was associated with more psychological symptoms and that higher cultural identity conflict would contribute to these associations.

Methods

We used data from the first wave of Karakter, a longitudinal study of 158 Syrians with refugee backgrounds (69.0% men, age range 18–35). Participants completed a questionnaire assessing PTEs, PMLPs, stressful life events, cultural identity conflict, and symptoms of anxiety/depression and posttraumatic stress.

Results

Correlational analyses indicated that more PTEs and stressful life events were related to higher levels of cultural identity conflict and more psychological symptoms. Furthermore, greater cultural identity conflict was associated with more psychological symptoms. We did not observe indirect effects of cultural identity conflict in the mediation analyses.

Conclusions

Results suggest that postmigration stressors and cultural identity conflict are associated with psychological symptoms among Syrian emerging adults who have resettled in the Netherlands.     

Children's experience of life stress: The role of family social support and social problem-solving skills as protective factors

Examined the role of family social support and social problem-solving skills in moderating the effects of children's stressful life events on behavioral adjustment. Participants were 322 fourth and fifth graders who reported on their stressful experiences during the past year. Children from both regular education (RE) or special education (SE) classrooms were included in the sample. Additional self-report data from children also included measures related to perceived level of family social support, a personality questionnaire, and a social problem-solving measure. In addition, teachers provided reports of the children's behavior and adjustment. Main effects were found for total stress, school/peer stress, family social support, and social problem solving. Significant moderator effects were found for family support on total stress for the teacher-reported internalizing problems of RE students and for family support on school/peer stress on the teacher-reported externalizing problems and self-reported anxiety problems of SE students. Specific, theory-generated hypotheses are discussed as a more effective method of examining relations between stress and various moderator variables.     

Major and minor life events as predictors of psychological distress: Further issues and findings

Current trends in research on stressful life events and disease have been to focus upon other psychosocial factors that may be associated with stress and illness relationships. Recently, the study of relatively minor life events or situations (e.g., daily hassles) has provided a promising alternative avenue of inquiry into basic stress measurement and the relationship of stress to disorder. While initial findings in this area of research appear encouraging, several methodological and procedural issues currently preclude definitive conclusions. The present paper outlines several of the most important limitations of existing research on this topic and provides further data taking these limitations into account for the role of minor life events as predictors of psychological distress. The results of the present prospective study indicate that undesirable minor events (e.g., hassles) significantly predict psychological symptoms, even once initial symptom status is controlled for statistically. Additionally, hassles were uniformly better predictors of subsequent psychological symptoms than were major life event categories; potentially important interactive effects (e.g., hassles x prior symptoms; hassles x prior major events) were also tested and their implications are discussed. Finally, basic associations between major and minor events were examined. The findings are discussed specifically in the context of recent advances in this area and more generally in relation to clarifying our understanding of psychosocial predictors of disorder.     

Depression and sensitization to stressors among young women as a function of childhood adversity

The authors tested a stress-sensitization version of a diathesis-stress approach to depression. In a 2-year longitudinal follow-up design, exposure to stressful life events was examined in young women in the transition to adulthood. The authors hypothesized that those who had experienced one or more significant childhood adversities would have a lower threshold for developing a depressive reaction to stressors. Results indicated that women with exposure to one or more childhood adversities--such as family violence, parent psychopathology or alcoholism, and others--were more likely to become depressed following less total stress than women without such adversity. The results could not be accounted for by chronic stress or prior depression. Both biological and psychological sensitization mechanisms may be speculated to play a role, but the actual mechanisms of stress sensitization remain to be explored.     

Early childhood adversity and adolescent depression: the mediating role of continued stress

BACKGROUND: While various conceptualizations of the link between childhood adversity and later depression have been offered, most have not accounted for the possibility that early adversity predicts continuing stress proximal to depression onset. Thus, the present study tested the possible mediating role of recent stress in the association between early adversity and depression in late adolescence.METHOD: Study questions were examined in a longitudinal community sample of 705 youth who were contemporaneously assessed for early adversity exposure prior to age 5 years, chronic and episodic stress at age 15 years, and major depression prior to age 15 years and between 15 and 20 years. RESULTS: Total youth stress burden at age 15 years mediated the effect of early adversity on depression between ages 15 and 20 years, and none of the observed relationships were moderated by onset of depression prior to age 15 years. CONCLUSIONS: These findings suggest that continued stress exposure proximal to depression onset largely accounts for the association between early adversity and depression in late adolescence. Intervention should thus focus on disrupting the continuity of stressful conditions across childhood and adolescence. Future studies of the neurobiological and psychosocial mechanisms of the link between early experiences and depression should explore whether the effects of early experiences are independent of continuing adversity proximal to depressive onset.     

Stress and other psychosocial characteristics of patients with psychogenic nonepileptic seizures

Research on psychogenic nonepileptic seizures (PNES) has focused on childhood abuse, but less is known about other stressors and psychosocial risk factors. The authors compared 25 patients with PNES with 33 control subjects with epilepsy on stressful life events and other risk factors for somatoform disorders. Compared with control subjects, patients with PNES reported significantly more prevalent and stressful negative life events (including adulthood abuse) and more current rumination, stress-related diseases, somatic symptoms, bodily awareness, and marginally more anxiety and depression. However, the relationship of many of these variables to PNES was accounted for by life stress. Groups did not differ on illness worry, alexithymia, or psychotic symptoms. The results suggest that PNES are part of a larger pattern of somatic symptoms responses to a wide range of negative events, including stress in adulthood.     

Prenatal stress has long-term effects on behavioral responses to stress in juvenile rhesus monkeys

The effect of maternal psychological disturbance during pregnancy on postnatal responses of the offspring to stressful events was investigated in juvenile rhesus monkeys. Six pregnant monkeys were repeatedly removed from their home cages and briefly exposed to unpredictable noise during mid to late gestation (Days 90–145 postconception). Six undisturbed pregnant mothers served as controls. Behavioral data were later collected from the 18-month-old offspring under a baseline and four progresssively stressful conditions. Social behaviors were considerably more affected by prenatal treatment than nonsocial behaviors. Prenatally stressed offspring showed more abnormal social behavior (mutual clinging) and less normal social behavior (proximity, contact) than controls. These results suggest that offspring of mothers stressed during pregnancy may show enhanced responsivity to stressors later in life, and concur with rodent findings indicating that prenatal stress may have long-term effect on behavioral reactivity. © 1993 Wiley & sons.

Religious coping and psychological adjustment to stress: a meta-analysis

A growing body of literature suggests that people often turn to religion when coping with stressful events. However, studies on the efficacy of religious coping for people dealing with stressful situations have yielded mixed results. No published studies to date have attempted to quantitatively synthesize the research on religious coping and psychological adjustment to stress. The purpose of the current study was to synthesize the research on situation-specific religious coping methods and quantitatively determine their efficacy for people dealing with stressful situations. A meta-analysis of 49 relevant studies with a total of 105 effect sizes was conducted in order to quantitatively examine the relationship between religious coping and psychological adjustment to stress. Four types of relationships were investigated: positive religious coping with positive psychological adjustment, positive religious coping with negative psychological adjustment, negative religious coping with positive psychological adjustment, and negative religious coping with negative psychological adjustment. The results of the study generally supported the hypotheses that positive and negative forms of religious coping are related to positive and negative psychological adjustment to stress, respectively. Implications of the findings and their limitations are discussed.     

Psychological aspects of Crohn's disease

This is a critical review of 16 studies reporting a relationship between Crohn's disease and psychological variables. The studies reviewed indicate a relationship between the psychological variables of stressful life events, personality characteristics, and psychopathology and the onset and/or exacerbation of Crohn's symptoms. Personality characteristics such as depression, anxiety, and dependency are frequently reported as are the occurrence of stressful life events and the presence of psychopathology. The nature of the relationship is not explained by the research to date; however, the findings summarized in this report indicate that additional investigation into this association is warranted. A plan for such research is suggested.     

Life problems,social supports,and psychological functioning of emotionally disturbed and well low-income women

The relationship between stressful life events, social supports, and psychological functioning was examined in a low-income population of schizophrenic, depressed, and well mothers of young children. It was expected that the disturbed populations and those rated lowest on psychological functioning would have the most problems and the fewest resources. A buffering effect was hypothesized such that for the individuals with many problems, those with many resources would show better functioning than those with few resources. The results indicated that neither number of problems nor number of resources was related significantly to levels of psychological functioning. For disturbed women, having fewer problems may be associated with higher functioning. Both schizophrenic and depressed women reported more problems, but also more resources, than well women. Finally, having many resources did not affect the level of functioning of those with many stressful life events. Results were interpreted as failing to support the buffering hypothesis. Alternative explanations are proposed in terms of factors predisposing to vulnerability (e.g., low self-esteem) and alternative conceptualizations of social support.
