Item Open Access All my children: The roles of semantic category and phonetic similarity in the misnaming of familiar individuals.(Mem Cognit, 2016-10) Deffler, Samantha A; Fox, Cassidy; Ogle, Christin M; Rubin, David CDespite knowing a familiar individual (such as a daughter) well, anecdotal evidence suggests that naming errors can occur among very familiar individuals. Here, we investigate the conditions surrounding these types of errors, or misnamings, in which a person (the misnamer) incorrectly calls a familiar individual (the misnamed) by someone else's name (the named). Across 5 studies including over 1,700 participants, we investigated the prevalence of the phenomenon of misnaming, identified factors underlying why it may occur, and tested potential mechanisms. We included undergraduates and MTurk workers and asked questions of both the misnamed and the misnamer. We find that familiar individuals are often misnamed with the name of another member of the same semantic category; family members are misnamed with another family member's name and friends are misnamed with another friend's name. Phonetic similarity between names also leads to misnamings; however, the size of this effect was smaller than that of the semantic category effect. Overall, the misnaming of familiar individuals is driven by the relationship between the misnamer, misnamed, and named; phonetic similarity between the incorrect name used by the misnamer and the correct name also plays a role in misnaming.Item Open Access Changes in neuroticism following trauma exposure.(J Pers, 2014-04) Ogle, Christin M; Rubin, David C; Siegler, Ilene CUsing longitudinal data, the present study examined change in midlife neuroticism following trauma exposure. Our primary analyses included 670 participants (M(age) = 60.55; 65.22% male, 99.70% Caucasian) who completed the NEO Personality Inventory at ages 42 and 50 and reported their lifetime exposure to traumatic events approximately 10 years later. No differences in pre- and post-trauma neuroticism scores were found among individuals who experienced all of their lifetime traumas in the interval between the personality assessments. Results were instead consistent with normative age-related declines in neuroticism throughout adulthood. Furthermore, longitudinal changes in neuroticism scores did not differ between individuals with and without histories of midlife trauma exposure. Examination of change in neuroticism following life-threatening traumas yielded a comparable pattern of results. Analysis of facet-level scores largely replicated findings from the domain scores. Overall, our findings suggest that neuroticism does not reliably change following exposure to traumatic events in middle adulthood. Supplemental analyses indicated that individuals exposed to life-threatening traumas in childhood or adolescence reported higher midlife neuroticism than individuals who experienced severe traumas in adulthood. Life-threatening traumatic events encountered early in life may have a more pronounced impact on adulthood personality than recent traumatic events.Item Open Access Commentary-Pre- and Posttrauma Predictors of Posttraumatic Stress Disorder Symptom Severity: Reply to van der Velden and van der Knaap (2017).(Clinical psychological science : a journal of the Association for Psychological Science, 2017-01) Ogle, Christin M; Rubin, David C; Siegler, Ilene CItem Open Access Cumulative exposure to traumatic events in older adults.(Aging Ment Health, 2014) Ogle, Christin M; Rubin, David C; Siegler, Ilene COBJECTIVES: The present study examined the impact of cumulative trauma exposure on current posttraumatic stress disorder (PTSD) symptom severity in a nonclinical sample of adults in their 60s. The predictive utility of cumulative trauma exposure was compared to other known predictors of PTSD, including trauma severity, personality traits, social support, and event centrality. METHOD: Community-dwelling adults (n = 2515) from the crest of the Baby Boom generation completed the Traumatic Life Events Questionnaire, the PTSD Checklist, the NEO Personality Inventory, the Centrality of Event Scale, and rated their current social support. RESULTS: Cumulative trauma exposure predicted greater PTSD symptom severity in hierarchical regression analyses consistent with a dose-response model. Neuroticism and event centrality also emerged as robust predictors of PTSD symptom severity. In contrast, the severity of individuals' single most distressing life event, as measured by self-report ratings of the A1 PTSD diagnostic criterion, did not add explanatory variance to the model. Analyses concerning event categories revealed that cumulative exposure to childhood violence and adulthood physical assaults were most strongly associated with PTSD symptom severity in older adulthood. Moreover, cumulative self-oriented events accounted for a larger percentage of variance in symptom severity compared to events directed at others. CONCLUSION: Our findings suggest that the cumulative impact of exposure to traumatic events throughout the life course contributes significantly to posttraumatic stress in older adulthood above and beyond other known predictors of PTSD.Item Open Access Neuroticism Increases PTSD Symptom Severity by Amplifying the Emotionality, Rehearsal, and Centrality of Trauma Memories.(Journal of personality, 2017-10) Ogle, Christin M; Siegler, Ilene C; Beckham, Jean C; Rubin, David COBJECTIVE:Although it is well established that neuroticism increases the risk of posttraumatic stress disorder (PTSD), little is known about the mechanisms that promote PTSD in individuals with elevated levels of neuroticism. Across two studies, we examined the cognitive-affective processes through which neuroticism leads to greater PTSD symptom severity. METHOD:Community-dwelling adults with trauma histories varying widely in severity (Study 1) and clinically diagnosed individuals exposed to DSM-IV-TR A1 criterion traumas (Study 2) completed measures of neuroticism, negative affectivity, trauma memory characteristics, and PTSD symptom severity. RESULTS:Longitudinal data in Study 1 showed that individuals with higher scores on two measures of neuroticism assessed approximately three decades apart in young adulthood and midlife reported trauma memories accompanied by more intense physiological reactions, more frequent involuntary rehearsal, and greater perceived centrality to identity in older adulthood. These properties of trauma memories were in turn associated with more severe PTSD symptoms. Study 2 replicated these findings using cross-sectional data from individuals with severe trauma histories and three additional measures of neuroticism. CONCLUSIONS:Results suggest that neuroticism leads to PTSD symptoms by magnifying the emotionality, availability, and centrality of trauma memories as proposed in mnemonic models of PTSD.Item Open Access Participant, rater, and computer measures of coherence in posttraumatic stress disorder.(J Abnorm Psychol, 2016-01) Rubin, David C; Deffler, Samantha A; Ogle, Christin M; Dowell, Nia M; Graesser, Arthur C; Beckham, Jean CWe examined the coherence of trauma memories in a trauma-exposed community sample of 30 adults with and 30 without posttraumatic stress disorder. The groups had similar categories of traumas and were matched on multiple factors that could affect the coherence of memories. We compared the transcribed oral trauma memories of participants with their most important and most positive memories. A comprehensive set of 28 measures of coherence including 3 ratings by the participants, 7 ratings by outside raters, and 18 computer-scored measures, provided a variety of approaches to defining and measuring coherence. A multivariate analysis of variance indicated differences in coherence among the trauma, important, and positive memories, but not between the diagnostic groups or their interaction with these memory types. Most differences were small in magnitude; in some cases, the trauma memories were more, rather than less, coherent than the control memories. Where differences existed, the results agreed with the existing literature, suggesting that factors other than the incoherence of trauma memories are most likely to be central to the maintenance of posttraumatic stress disorder and thus its treatment.Item Open Access Scientific evidence versus outdated beliefs: A response to Brewin (2016).(Journal of abnormal psychology, 2016-10) Rubin, David C; Berntsen, Dorthe; Ogle, Christin M; Deffler, Samantha A; Beckham, Jean CWe find Brewin's (2016) critiques of the narratives, power, and coherence measures in Rubin et al. (2016) without merit; his suggestions for a "revised formulation" (p. 1015) of coherence are contradicted by data readily available in the target article but ignored. We place Brewin's commentary in a historical context and show that it reiterates views of trauma memory fragmentation that are unsupported by data. We evaluate an earlier review of fragmentation of trauma memories (Brewin, 2014), which Brewin uses to support his position in the commentary. We show that it is contradicted by more comprehensive reviews and fails to include several studies that met Brewin's inclusion criteria but provided no support for his position, including 3 studies by the present authors (Rubin, 2011; Rubin, Boals, & Berntsen, 2008; Rubin, Dennis, & Beckham, 2011). In short, the commentary's position does not stand against scientific evidence; attempts to rescue it through arguments unsupported by data advance neither science nor clinical practice. (PsycINFO Database RecordItem Open Access The Frequency and Impact of Exposure to Potentially Traumatic Events Over the Life Course.(Clin Psychol Sci, 2013-10-01) Ogle, Christin M; Rubin, David C; Berntsen, Dorthe; Siegler, Ilene CWe examined the frequency and impact of exposure to potentially traumatic events among a nonclinical sample of older adults (n = 3,575), a population typically underrepresented in epidemiological research concerning the prevalence of traumatic events. Current PTSD symptom severity and the centrality of events to identity were assessed for events nominated as currently most distressing. Approximately 90% of participants experienced one or more potentially traumatic events. Events that occurred with greater frequency early in the life course were associated with more severe PTSD symptoms compared to events that occurred with greater frequency during later decades. Early life traumas, however, were not more central to identity. Results underscore the differential impact of traumatic events experienced throughout the life course. We conclude with suggestions for further research concerning mechanisms that promote the persistence of post-traumatic stress related to early life traumas and empirical evaluation of psychotherapeutic treatments for older adults with PTSD.Item Open Access The impact of the developmental timing of trauma exposure on PTSD symptoms and psychosocial functioning among older adults.(Dev Psychol, 2013-11) Ogle, Christin M; Rubin, David C; Siegler, Ilene CThe present study examined the impact of the developmental timing of trauma exposure on posttraumatic stress disorder (PTSD) symptoms and psychosocial functioning in a large sample of community-dwelling older adults (N = 1,995). Specifically, we investigated whether the negative consequences of exposure to traumatic events were greater for traumas experienced during childhood, adolescence, young adulthood, midlife, or older adulthood. Each of these developmental periods is characterized by age-related changes in cognitive and social processes that may influence psychological adjustment following trauma exposure. Results revealed that older adults who experienced their currently most distressing traumatic event during childhood exhibited more severe symptoms of PTSD and lower subjective happiness compared with older adults who experienced their most distressing trauma after the transition to adulthood. Similar findings emerged for measures of social support and coping ability. The differential effects of childhood compared with later life traumas were not fully explained by differences in cumulative trauma exposure or by differences in the objective and subjective characteristics of the events. Our findings demonstrate the enduring nature of traumatic events encountered early in the life course and underscore the importance of examining the developmental context of trauma exposure in investigations of the long-term consequences of traumatic experiences.Item Open Access The relation between insecure attachment and posttraumatic stress: Early life versus adulthood traumas.(Psychological trauma : theory, research, practice and policy, 2015-07) Ogle, Christin M; Rubin, David C; Siegler, Ilene CThe present study examined the relations between insecure attachment and posttraumatic stress disorder (PTSD) symptoms among community-dwelling older adults with exposure to a broad range of traumatic events. Attachment anxiety and attachment avoidance predicted more severe symptoms of PTSD and explained unique variance in symptom severity when compared to other individual difference measures associated with an elevated risk of PTSD, including NEO neuroticism and event centrality. A significant interaction between the developmental timing of the trauma and attachment anxiety revealed that the relation between PTSD symptoms and attachment anxiety was stronger for individuals with current PTSD symptoms associated with early life traumas compared to individuals with PTSD symptoms linked to adulthood traumas. Analyses examining factors that account for the relation between insecure attachment and PTSD symptoms indicated that individuals with greater attachment anxiety reported stronger physical reactions to memories of their trauma and more frequent voluntary and involuntary rehearsal of their trauma memories. These phenomenological properties of trauma memories were in turn associated with greater PTSD symptom severity. Among older adults with early life traumas, only the frequency of involuntary recall partially accounted for the relation between attachment anxiety and PTSD symptoms. Our differential findings concerning early life versus adulthood trauma suggest that factors underlying the relation between attachment anxiety and PTSD symptoms vary according to the developmental timing of the traumatic exposure. Overall our results are consistent with attachment theory and with theoretical models of PTSD according to which PTSD symptoms are promoted by phenomenological properties of trauma memories.
