The Reformulated theory of learned helplessness emphasizes maladaptive explanatory style and its influence on depression, achievement, health, and coping. Individuals who habitually explain unpleasant/uncontrollable events by internal, stable and global causes (and good events by external, unstable, specific causes) are said to have a maladaptive explanatory style. Researchers speculate that negative life events (such as parental divorce or death) contribute to the development of this style. Researchers have sought to explain adjustment-related difficulties by focusing on traumatic life events, such as divorce or death of a parent and their adverse effects on childhood development.Literature concerning the correlates of father absence, divorce, parental death, attachment and stressful life events shows that closeness to parents can mediate the impact of these events on adjustment and development. The mediating effects of closeness to parent may explain why not all children who experience these events actually develop maladaptive explanatory styles.This investigation examined the relations between Negative Life Events, Closeness to Parent and Explanatory Style. By looking at these relations, we can determine which variable is more influential in developing the maladaptive style. It was expected that Closeness to Parent would be a better predictor of explanatory style than Negative Life Events.Participants were 86 college students who completed a questionnaire that assessed explanatory style, closeness to parent, negative life events, and level of depression. Multiple regression was used to determine the significant predictors of explanatory style and depression. Results showed that none of the variables were significant predictors of explanatory style. Recent life events, closeness to mother and explanatory style were significant predictors of depression. Discriminant analysis was used to determine whether participants whose parents were divorced could be differentiated from those whose parent's marriage was intact using explanatory style, closeness to parent and depression as predictors. Results showed no significant differences between these groups. Sample group means for depression and life events were higher than those from normative studies for the Beck Depression Inventory and the Life Experience Survey.As the literature showed, closeness to parent and negative life events should account for some of the variance in the maladaptive style. The absence of these relations may be attributed to theoretical and methodological issues concerning closeness to parent and explanatory style.However, since this sample had high levels of depression and life stress, theoretically these relations should have been found. This points to the importance of the problems discussed.Prospective longitudinal studies, although costly and time consuming may be useful in determining the antecedents of a maladaptive explanatory style. / Department of Psychological Science

Do people become more optimistic about future adjustment to negative life events after rumination? Past research using a "top of the head" paradigm indicates that people estimate they would adjust more poorly for severe events and better for mild negative events than their peers. Selective focus (i.e., differential accessibility of information about assets and liabilities for coping) has been provided as an explanation for this effect, which is counter to research on "optimistic bias". Martin and Tesser's (1989) rumination model was applied to beliefs about one's comparative adjustment to negative life events. One hundred twenty undergraduate subjects were asked to imagine experiencing a Severe (HIV+) or Mild (Herpes) negative event at some future time, then to designate items on a reaction time task as either an Asset or Liability in coping with the event. The reaction time task and subsequent comparative adjustment ratings were made either immediately, after a delay that allowed for rumination, or after a delay without an opportunity for rumination. A thought-listing analysis of the audiotaped ruminations revealed that, as predicted, subjects became more optimistic over time. They initially discussed liabilities in coping with the Severe event but gradually considered assets. Comparative adjustment ratings for the Severe event were not significantly different than for the Mild event, even in the Rumination Absent condition. It was suggested that temporarily making assets for coping accessible through the reaction time task had the same effect on comparative adjustment ratings as did problem-solving through rumination. The reaction time data provided convergent evidence regarding selective focus and complimented a thought-listing paradigm used in previous studies. / Master of Science

Thesis (MSc (Physiological Sciences))--University of Stellenbosch, 2006. / Early adverse life events appear to increase the susceptibility of developing psychiatric disorders later in life. The molecular mechanisms involved in the development of pathological behaviour remain unclear. Dysregulation of the hypothalamic-pituitary-adrenal axis and alterations in neurotrophic factors have been implicated.

Previous research indicates that those with a history of abuse have an increased risk to experience subsequent traumatic events. This study utilized a convenience sample of undergraduate students to examine the reaction of those with a history of abuse to subsequent traumatic experiences. In addition, the study assessed the level of posttraumatic growth an individual experiences following childhood abuse. The level of posttraumatic growth was examined to determine if the growth allowed for participants to better handle successive traumas. Those with a history of abuse experienced higher levels of symptomology following a successive traumatic event. Results did not support the hypothesis that among those with a history of abuse, lower levels of posttraumatic growth would predict higher levels of symptoms following a later trauma. Implications and limitations of the study, as well as directions for future research are discussed.

Mode of access: World Wide Web. / Thesis (Ph. D.)--University of Hawaii at Manoa, 2005. / Evidence suggests that routine screening of primary care patients for exposure to traumatic life events, and particularly assaultive trauma, may yield both clinical and cost benefits for healthcare systems (e.g., Green, Epstein, Krupnick, & Rowland, 1997; Lecrubier, 2004). However, although advocated by authorities, such screening has yet to be widely adopted. A sample of female university healthcare patients (N = 339) was assessed for exposure to trauma in order to examine several unaddressed issues that may diminish the clinical utility of screening for trauma in primary care patients. First, because the length of the traditional trauma history assessment makes it less acceptable for use in time-pressured primary care settings, the discriminative validity of a brief, self-administered screening question about exposure to trauma, the Structured Clinical Interview for DSM-IV (SCID) posttraumatic stress disorder (PTSD) module's screening question (First, Spitzer, Williams & Gibbon, 1997) was compared to a longer, inventory method of assessment, the Traumatic Life Events Questionnaire (TLEQ, Kubany et al., 2000). Second, because it is unclear whether patients who have experienced assaultive trauma will disclose these experiences when asked in a primary care setting, the relative predictive efficacy of informing respondents that their responses would, or would not be, disclosed to health center personnel was evaluated. Two versions of the brief screening question were assessed across two instructional sets regarding disclosure, to determine each condition's relative classification accuracy for identifying respondents who reported experiences of sexual or physical assault, and/or symptoms of PTSD. The brief screen identified more than three-quarters of the survivors of traumatic assault; and more importantly, identified almost all of the women who reported significant PTSD symptomatology: the inventory method identified only 2 additional women of the 47 who met criteria for PTSD. Although survivors of sexual assault were significantly less likely to disclose their history to their provider, no differences were found for those assault survivors who also reported symptoms of PTSD. Results suggest that a brief screening question about traumatic life events may be an acceptable option in settings where more time-consuming assessment procedures are not practical. / Includes bibliographical references (leaves 83-98). / Electronic reproduction. / Also available by subscription via World Wide Web / x, 98 leaves, bound 29 cm

The results of this study revealed that despite the childhood sexual abuse event, the victims were able to change their views in a positive direction with regard to the benevolence of the world and people as they marched through life and presumably experienced positive events.
