An investigation of traumatic life events and obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD), like most other psychiatric disorders, is suspected of being influenced by an interaction between life events and genes, both with regard to onset and course of illness. To date, no specific genes have been identified as playing a frequent role, and only a relatively few empirical studies have assessed the association between stressful life events (SLEs) and OCD. The present study builds on past research by examining the potential contributions from traumatic life events (TLEs) on the severity and symptom features in 265 individuals with Structured Clinical Interview for DSM-IV (SCID)-diagnosed OCD. Of these participants 54% endorsed having experienced at least one TLE in their life time. The presence of one or more TLEs was associated with increased OCD symptom severity. This relationship remained significant despite controlling for key variables including age, OCD age-of-onset, comorbidity, and depressive symptoms. In addition, obsessions/checking and symmetry/ordering were two of four symptom factors that were specifically associated with the occurrence of TLEs. These results are generally supportive of a pathoplastic relationship between TLEs and OCD symptomatology and thus suggest the need for greater systematic consideration of life stresses in research focused on the nature and treatment of OCD.     

Ethnic and Racial Differences in Life Stress Among High School Adolescents

L. A. Slavin, K. L. Rainer, M. L. McCreary, and K. K. Gowda's (1991) Multicultural Model of the Stress Process was used as the basis for exploring ethnic and racial differences in the life stress process among 103 Black, 129 Hispanic, and 105 White high school students from a multiethnic, predominantly minority, large urban school district. Cross-group comparisons were made on life stress exposure, appraisal of negative event impact, social support, and psychological symptomatology. White adolescents reported more negatively impactful stressful life events and lower levels of received social support than did Black or Hispanic adolescents. Minority status predicted ethnic and racial differences independent of socioeconomic status.     

The incidence of stressful life events of elementary school-aged children

Certain events, commonly found in the life histories of children, have been characterized as potentially stressful (Rutter, 1981). There is some evidence to support the hypothesis that these events play a role in the etiology of various disorders, although the nature of that relationship is not clear (Dohrenwend & Dohrenwend, 1974). Yet that relationship remains the subject of considerable interest, as can be seen by the number of studies on the influence of stressful life events on children's emotional adjustment and school performance (Boike, Gesten, Cowen, Felner, & Francis, 1978; Felner, Ginter, Boike, & Cowen, 1981; Felner, Stolberg, & Cowen, 1975; Gesten, Scher, & Cowen, 1981; Felner, Stolberg, & Cowen, 1975; Gesten, Scher, & Cowen, 1978; Rolf & Garmezy, 1974; Sandler & Block, 1979; Siegel, 1981). Sandler and Ramsey (1980) have suggested that the role of life events as stressors can be understood to be a function of, among other things, the frequency of occurrence of events. For research and clinical assessment purposes, baseline data on the incidence of stressful life events of children seem to be necessary. In order to collect and organize baseline data, the relevant demographic variables must be identified. It was hypothesized that there might be two relevant demographic variables: age and socioeconomic status (SES). The purposes of this study were to (a) conduct a survey to gather baseline data on the incidence of stressful life events of children, and (b) examine the effects of age and SES on the number of events reported.     

Intergroup consensus/disagreement in support of group-based hierarchy: an examination of socio-structural and psycho-cultural factors

A meta-analysis examined the extent to which socio-structural and psycho-cultural characteristics of societies correspond with how much gender and ethnic/racial groups differ on their support of group-based hierarchy. Robustly, women opposed group-based hierarchy more than men did, and members of lower power ethnic/racial groups opposed group-based hierarchy more than members of higher power ethnic/racial groups did. As predicted by social dominance theory, gender differences were larger, more stable, and less variable from sample to sample than differences between ethnic/racial groups. Subordinate gender and ethnic/racial group members disagreed more with dominants in their views of group-based hierarchy in societies that can be considered more liberal and modern (e.g., emphasizing individualism and change from traditions), as well as in societies that enjoyed greater gender equality. The relations between gender and ethnic/racial groups are discussed, and implications are developed for social dominance theory, social role theory, biosocial theory, social identity theory, system justification theory, realistic group conflict theory, and relative deprivation theory.

Memory in posttraumatic stress disorder: properties of voluntary and involuntary, traumatic and nontraumatic autobiographical memories in people with and without posttraumatic stress disorder symptoms

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were made of memories of stressful events versus control events and involuntary versus voluntary memories in people high versus low in posttraumatic stress disorder (PTSD) symptom severity. For all participants, stressful memories had more emotional intensity, more frequent voluntary and involuntary retrieval, but not more fragmentation. For all memories, participants with greater PTSD symptom severity showed the same differences. Involuntary memories had more emotional intensity and less centrality to the life story than voluntary memories. Meeting the diagnostic criteria for traumatic events had no effect, but the emotional responses to events did. In 533 undergraduates, correlations among measures were replicated and the Negative Intensity factor of the Affect Intensity Measure correlated with PTSD symptom severity. No special trauma mechanisms were needed to account for the results, which are summarized by the autobiographical memory theory of PTSD.     

Gender differences in depressive response: The role of social support

The present study investigated the possibility that women's ruminative response style to stressful events is due in part to differential advice that women and men receive from their social support networks. Undergraduates (60 men, 136 women) of various ethnic backgrounds (e.g., 21.4% English, 16.8% West Indian, 12.8% Chinese, 10.7% Italian) indicated the extent to which they would endorse various statements of advice for a stimulus person described as experiencing a negative life event. As predicted, subjects endorsed more ruminative advice for female stimulus persons than for male stimulus persons (p< .02). These findings imply that, since females in stressful situations seem more likely to receive ruminative advice than do their male counterparts, women's greater vulnerability to depressive symptoms may be partly the result of the concomitant dangers of stressful events and potentially harmful advice.     

Gender identity and adjustment in black, Hispanic, and white preadolescents

The generality of S. K. Egan and D. G. Perry's (2001) model of gender identity and adjustment was evaluated by examining associations between gender identity (felt gender typicality, felt gender contentedness, and felt pressure for gender conformity) and social adjustment in 863 White, Black, and Hispanic 5th graders (mean age = 11.1 years). Relations between gender identity and adjustment varied across ethnic/racial groups, indicating that S. K. Egan and D. G. Perry's model requires amendment. It is suggested that the implications of gender identity for adjustment depend on the particular meanings that a child attaches to gender (e.g., the specific attributes the child regards as desirable for each sex); these meanings may vary across and within ethnic/racial groups. Cross-ethnic/racial investigation can aid theory building by pointing to constructs that are neglected in research with a single ethnic/racial group but that are crucial components of basic developmental processes.     

Stressful life events in countries of differing economic development: Nicaragua, Chile, and Spain

the aim was to describe a study involving 481 psychology students in the last courses of their degrees (M age = 21.9 yr., SD=4.2; 94 men and 386 women) from Nicaragua, Chile, and Spain. The study examined the potential risk of experiencing certain stressful life events, the number of stressors, and their characteristics. Also were analyzed the strength of their relation to social class and stressful life events experienced. Greater presence of stressful life events were reported among people from less developed countries, Chile and Nicaragua, and among people belonging to lower social class.     

Distressing Relationships,Anger, and Stress Amplification in a Sample of Young Adult African Americans

This study examined the impact of relationship distress in a sample of 637 African American young adults from the Family and Community Health Study. Using data from privately collected, in-depth interviews, we assessed how distress in nonmarital romantic partnerships and best friendships influence anger. While social support researchers have examined the stress buffering influence of supportive relationships, we utilized the principle of negative potency to test the stress amplification effect of relationship distress through an assessment of stressful life events and racial discrimination. Our analysis showed that distress in relationships was associated with anger, while the presence of these relationships was not. Support for the stress amplification hypothesis was found as men and women who experience intense racial discrimination coupled with a more hostile best friend had elevated levels of anger. Gender differences were also evident and discussed.     

PTSD Symptom Patterns Following Traumatic and Nontraumatic Events

This study extends research examining posttraumatic stress disorder symptoms following different types of potentially traumatic events. Specifically, the study examined and compared the symptom patterns observed in those who suffered a major accident, the unexpected death of a loved one, or sexual assault. Based on recent findings, this project also examines those who reported nontraumatic (but stressful) events, as well as comparing symptom patterns across gender. Findings suggest different types of traumas might be associated with differences in severity and patterns of symptoms for women (but not for men), suggesting symptom patterns manifest differently in men and women. Results also call into question the assumption that traumatic events demonstrate different symptom patterns than other types of events.     

Links Between Stressful Life Events and Proactive and Reactive Functions of Aggression

Recently, more attention has been devoted to understanding how stressful life events might relate to proactive and reactive aggression. Findings suggest that stressful life events are more strongly linked to reactive, than proactive, aggression; however, it is unclear whether the impact of stressful life events on proactive and reactive aggression might vary as a function of the level of exposure to or type of stressful life event. The current study examined how level of exposure to stressful life events (i.e., witnessed, experienced, and learned about) and stressful life event types (i.e., war zone exposure, sexual victimization, interpersonal violence, and other trauma exposure) related to proactive and reactive aggression. The sample was comprised of 500 undergraduate students (M = 18.96, SD = 1.22, 49.6% male) recruited from a Midwestern university. Findings indicated that all three levels of stressful life event exposure (i.e., experienced, witnesses, and learned) were associated with reactive aggression; however, only witnessed stressful life events were associated with proactive aggression. Clinical implications and future directions are discussed.     

Psychological distress,stressful life events,and religiosity in younger African American adults

Prior research has found that stressful life events relate to increased psychological distress as well as mental and physical morbidity, particularly in minority groups. However, there is limited understanding of factors that may influence this relationship. This paper examines psychological distress, stressful life events, and religiosity among younger African American adults between the ages of 18 and 43 (n?=?215). Stressful life events and religiosity levels did not differ by gender, though females reported greater levels of each distress category. Female gender and stressful events were predictive of increased levels of distress. Dimensions of religiosity related in unique ways to individual categories of distress. This would suggest that the role of religion in reduced distress differs according to the type of religious experience. Intrinsic religiosity was found inversely related to both total distress and depression; organizational religiosity inversely related to somatization and obsessive-compulsiveness; finally, non-organizational religiosity was inversely related to interpersonal sensitivity. Further research is needed across additional sociodemographic and economic categories to further clarify the relationship of religiosity, stressful events, and distress in younger African American adults.     

Religious Resources,Spiritual Struggles,and Mental Health in a Nationwide Sample of PCUSA Clergy

A growing body of research explores patterns and correlates of mental health among clergy and other religious professionals. Our study augments this work by distinguishing between religious resources (i.e., support from church members, positive religious coping practices), and spiritual struggles (i.e., troubled relations with God, negative interactions with members, chronic religious doubts). We also explore several conceptual models of the interplay between these positive and negative religious domains and stressful life events. After reviewing theory and research on religious resources, spiritual struggles, and mental health, we test relevant hypotheses using data on a nationwide sample of ordained clergy members in the Presbyterian Church (USA). At least some support is found for all main effects hypotheses. Religious resources predict well-being more strongly, while spiritual struggles are more closely linked with psychological distress. There is some evidence that stressful life events erode mental health by fostering an elevated sense of spiritual disarray and struggle. We find limited support for the stress-buffering role of religious resources, and limited evidence for a stress-exacerbating effect of spiritual struggle. Study limitations are identified, along with a number of implications and promising directions for future research.     

National ethnic and racial disparities in disciplinary practices: A contextual analysis in American secondary schools

Previous research has documented ethnic/racial disparities in the implementation of school discipline, including exclusionary practices. The current study focused on ethnic/racial disparities in four types of school exclusionary policies through the Civil Rights Data Collection (2013–2014) based on 15,901 middle and 18,303 high schools from the United States. Consistent with an ecological model of multi-contextual influences, school- and region-level characteristics were tested in a multi-level analytic model. Sex, disability status, and ethnicity/race were estimated at level 1, with the following school-level predictors at level 2: proportion of youth eligible for free or reduced lunch, school size, diversity (percentage of students of different ethnicities/races in school), urban/suburban/rural locale, and region (Northeast, Midwest, South, and West). Findings provided robust evidence of persistent discrepancies in disciplinary practices across ethnic/racial groups. Specifically, African American students and students self-identifying as two or more races were found to be at greater risk for school discipline actions across all disciplinary measures in both middle and high schools. Regarding school-level variables, students from lower SES schools and smaller schools were at greater risk for some disciplinary measures. Unexpected findings were found for regional differences, as Midwestern schools had significantly higher rates for most disciplinary measures as compared to Southern schools. Moreover, ethnic/racial discrepancies were moderated by school-level characteristics, such that African American students and students self-identifying with two or more races were more likely to be disciplined at low SES schools and at schools with greater diversity.     

Parenting among Hispanic and Anglo-American mothers with young children

The authors examined parenting practices and developmental expectations among 38 Hispanic and 38 Anglo-American mothers living in the United States. Mothers of children 3 to 5 years of age completed the Parent Behavior Checklist (R. A. Fox, 1994), a 100-item measure of parents' developmental expectations, discipline, and nurturing practices. In addition, the authors appraised the Hispanic mothers' acculturation and selected them for participation if their scores on an acculturation scale indicated (a) that their lifestyle was predominantly Hispanic and (b) that they had not been assimilated into the dominant culture. The 2 ethnic groups were also divided by socioeconomic status (SES). There were significant main effects for ethnicity and SES on the discipline and nurturing scores but not on the expectations scores. The Hispanic and higher SES mothers reported higher discipline and lower nurturing scores than did the Anglo-American and lower SES mothers. An unexpected finding was the tendency for higher SES Hispanic mothers to report more frequent use of discipline than the other 3 groups.     

Stressful life events, motives for Internet use, and social support among digital kids.

This study presents the interrelationships between stressful life events, motives for Internet use, social support, and the use of the Internet among a sample of adolescents and children aged 8 to 18 (N = 717). The results show that stressful life events are significantly associated with the consumption of the Internet for mood management (such as entertainment and information seeking) and social compensation (such as recognition gaining and relationship maintenance) motives. Secondly, the more children and adolescents exhibit high levels of social support, either online or offline, the less they find stressful life events upsetting. Thirdly, as individuals exhibit greater ability to personally access different types of social support to meet their needs, their motivations for Internet use are characteristically more allied to mood-management and social-compensation. This study reasserts that the mental and physical impact of stressful life events are in fact buffered by one's degree of social support and Internet use, particular examples of which are entertainment and relationship maintenance, and positive coping strategies, which temporarily reduce stress and anxiety.     

Pathways Linking Child Physical Abuse,Depression, and Aggressiveness across Genders

Previous research suggests that child physical abuse, depression, and aggressiveness are linked, but gender differences remain poorly understood. This study examined gender differences in the mediational relationships among these constructs, after controlling for the confounding effects of other negative life events. Men and women completed questionnaires about physical abuse and negative life events that occurred prior to age 18, depressive symptoms, and aggressiveness. Results indicated significant gender differences in the pathways between child physical abuse and depression, and between child abuse and aggressiveness, with direct and mediating links pertaining only to men. These findings suggest that links among child physical abuse, depression, and aggressiveness are specific to men, and negative life events might play a more potent role for women.     

Couple resilience and life wellbeing in firefighters

The validity of the Couple Resilience Inventory was tested using 102 married or cohabiting firefighters. This instrument measures types of relationship behavior that often occur during stressful life events and that are expected to be associated with an ability to cope with employment in a stressful occupation. It includes scales measuring two nearly orthogonal dimensions, with one dimension pertaining to positive behavior and the other to negative. Firefighters completed an online questionnaire that included the Couple Resilience Inventory and measures of relationship satisfaction, exposure to traumatic events, and life wellbeing. In line with hypotheses, scales measuring positive and negative couple resilience were nearly orthogonal to each other, and distinct from a measure of relationship satisfaction, but both scales correlated positively with exposure to traumatic events, and both correlated in opposite directions with relationship satisfaction and life wellbeing. Results were consistent with the theoretical model and they supported instrument validity.     

Flashbulb memories and posttraumatic stress reactions across the life span: age-related effects of the German occupation of Denmark during World War II

A representative sample of older Danes were interviewed about experiences from the German occupation of Denmark in World War II. The number of participants with flashbulb memories for the German invasion (1940) and capitulation (1945) increased with participants' age at the time of the events up to age 8. Among participants under 8 years at the time of their most traumatic event, age at the time correlated positively with the current level of posttraumatic stress reactions and the vividness of stressful memories and their centrality to life story and identity. These findings were replicated in Study 2 for self-nominated stressful events sampled from the entire life span using a representative sample of Danes born after 1945. The results are discussed in relation to posttraumatic stress disorder and childhood amnesia.     

Phenomenal characteristics associated with real and imagined events: the effects of event valence and absorption

This study examined the effects of emotional valence of an event and individual differences in absorption on the phenomenal characteristics associated with real and imagined events. Each participant described four events. Two of these were real and two were imagined, with one pleasant and stressful event being generated for each category. Pleasant events (both real and imagined) contained more detail (visual detail, smell, and taste, and more information regarding location, time, etc.) than stressful events. In addition, higher levels of absorption were related to higher ratings for both real and imagined events (for both pleasant and stressful events). Discussion focused on implications for further research in source monitoring and other relevant domains. Copyright © 1999 John Wiley & Sons, Ltd.
