Personality traits moderate associations between word recall and subjective memory.

Cognitive gerontology research requires consideration of performance as well as perceptions of performance. While subjective memory is positively associated with memory performance, these correlations typically are modest in magnitude, leading to the need to consider whether certain people may show weaker or stronger linkages between performance and perceptions. The current study leveraged personality (NEO Big Five), memory performance (i.e., word recall), and perceptions of memory ability (i.e., metamemory in adulthood and memory decline) data from the St. Louis Personality and Aging Network (SPAN) study (n = 774, mean age: 71.52 years). Extraversion and conscientiousness held the most consistent associations with the cognitive variables of interest, as both traits were positively associated with metamemory and word recall, but negatively associated with subjective decline. Moreover, extraversion moderated associations between word recall and both memory capacity and complaints, insofar that objective-subjective associations were weaker for those adults higher in extraversion. These findings highlight the need to understand how personality influences the sources of information employed for subjective cognitive beliefs.

Personality pathology predicts increased informant-reported, but not performance-based, cognitive decline: Findings from two samples.

Research on the relationship between normal-range personality and cognitive aging has demonstrated consistent, modest effects. The current investigation increases our understanding of unhealthy cognitive aging by testing whether personality disorders (PDs), specifically borderline, avoidant, and obsessive-compulsive PDs, show prospective associations with the onset of cognitive problems. Interpersonal stressful life events and social support were expected to mediate these relationships. The current investigation used data from 2 longitudinal studies of older adulthood: the Alzheimer's disease Research Center cohort (ADRC, N = 434, Mage = 69.95, 56% women) and the St. Louis Personality and Aging Network study (SPAN, N = 1,058, Mage = 65.92, 54% women). The ADRC study administered a battery of neuropsychological tests to assess cognitive ability/memory. Borderline PD was measured with a composite from the NEO Five-Factor Inventory. The SPAN study administered self-, informant, and interview measures of the three PDs; a free-recall task; and an informant report measure of cognitive problems. Borderline PD features exhibited cross-sectional correlations with memory (ADRC: r = -.11; SPAN: all rs = -.08), general cognitive ability (ADRC: r = -.11), and informant-reported cognitive problems (rs ranged from .15 to .39). Most importantly, borderline PD features predicted an increase in informant-reported cognitive problems in SPAN participants (standardized bs = .13 and .15) over a 2-year period, but they did not predict a deterioration in the performance-based cognitive measures in either study. Avoidant and obsessive-compulsive PDs exhibited little association with cognitive aging. Neither interpersonal variable mediated any of these effects.

Neuroticism predicts informant reported cognitive problems through health behaviors.

OBJECTIVE: Personality traits have been linked to cognitive impairment, though work is needed to understand the mechanisms involved. Research also needs to consider alternative markers of cognitive impairment, such as informant report measures. The aim of the current study was to examine the role of health behaviors and social engagement as mediators for the relationship between personality and informant reported cognitive problems. It was expected that neuroticism would predict cognitive problems through negative health behaviors, while conscientiousness might predict cognitive problems through positive health behaviors. METHODS: Using data from the St. Louis Personality and Aging Network study at three time points, spanning approximately 2.27 years (N = 829, M age = 65.95), correlations were computed between the Big Five personality traits and health behaviors at wave 1, social engagement at wave 2, and informant reported cognitive problems at wave 3. Mediation tests examined whether health behaviors and social engagement explained the relationships found between personality and informant reported cognitive problems. RESULTS: Findings showed that neuroticism at wave 1 significantly predicted informant reported cognitive problems at wave 3 and that health behaviors, specifically wellness maintenance, partially explained this relationship. No significant associations were found between informant reported cognitive problems and conscientiousness, agreeableness, extraversion, openness, or social engagement. CONCLUSION: This study supports claims that neuroticism predicts later cognitive problems and expands on previous literature by demonstrating this relationship using an informant report measure. Furthermore, we found that health behaviors, and specifically wellness maintenance, account for some of the relationship between neuroticism and informant reported cognitive problems.

Unemployment and the Relationship between Borderline Personality Pathology and Health.

Evidence suggests that employment may buffer against the negative health outcomes associated with borderline personality disorder (BPD). The purpose of the current analyses was to examine unemployment and the BPD-health relationship prospectively. Participants were 1,536 older adults in a longitudinal study of health and aging, with repeated measures of physical health, depressive symptoms, and life satisfaction. We measured BPD features using multiple sources at baseline, and used principal components analysis to obtain latent scores. Multilevel models indicated that unemployment experiences did not moderate the prospective relationship between BPD features and physical health or life satisfaction, but did strengthen the positive relationship between BPD features and depressive symptoms. These findings provide insight into mechanisms of recovery for individuals with BPD.

Examining criterion a: DSM-5 level of personality functioning as assessed through life story interviews.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition alternative model for personality disorders offers a two-part definition of personality pathology, separating personality functioning from traits. The Level of Personality Functioning Scale (LPFS) from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition alternative model for personality disorders encapsulates the personality functioning criterion, and several methods have been used to assess it. Previous interview rating methods have overlapped with an assessment of personality traits and symptoms, biasing the assessment of functioning, and recently developed self-report instruments rely on the participant's awareness of their personality pathology. The purpose of the current analyses was to examine the reliability and validity of LPFS ratings based on open-ended, nondiagnostic interviews. The sample consisted of 162 community-dwelling, older adult participants from the St. Louis Personality and Aging Network. Undergraduate students rated video recordings of Life Story Interviews, using a 12-item version of the LPFS. One-way random, average measures intraclass correlation coefficient for the total LPFS was .80. A principal components analysis indicated that a single underlying dimension could characterize the LPFS. Component scores derived from this analysis demonstrated theoretically consistent associations with both normal-range and maladaptive personality traits. The component scores also contributed small but significant variance to the prediction of personality disorder symptoms, health, and functional outcomes over and above personality traits. These findings support the reliability and validity of the LPFS as assessed using Life Story Interviews and suggest that personality functioning ratings may have utility in predicting clinically relevant outcomes.

Borderline personality pathology and physical health: The role of employment.

Borderline personality disorder (BPD) is associated with negative physical health outcomes. Clinical case studies suggest that employment status may buffer against the negative effects of BPD on physical health. The goal of the current study was to examine the interaction between BPD features and employment status in predicting subjective perceptions of physical health. We hypothesized that employment status would moderate the relationship between BPD features and physical health, such that individuals who are employed would exhibit a weaker negative relationship between BPD features and self- and informant ratings of physical health. We investigated this question using data from a community sample of 1,630 middle-aged to older adults participating in the St. Louis Personality and Aging Network, an ongoing study of personality, health, and aging. Results indicated that employment status and BPD features were significant predictors of both self- and informant ratings of physical health. Confirming our hypothesis, the interaction term contributed to a significant increase in the proportion of explained variance, suggesting that employment is associated with a weaker negative relationship between BPD features and physical health. These findings highlight the importance of examining occupational functioning in the long-term course of BPD and offer avenues for further research into moderators of the relationship between BPD features and physical health.

Age-related outcomes associated with personality pathology in later life.

Methodological advances enable the latest research on personality pathology in later life to turn toward understanding the role personality pathology plays in age-related outcomes. Despite indications that some features of personality disorders fade in later life, a prevalence rate of approximately 10 percent has been established for adults aged 50 or older. Personality disorder features have been linked to suicidal ideation, poorer physical health, and cognitive decline in later life. Given these associations, the literature on treatment of personality disorders in this age group is surprisingly scant. Future research needs to address this lack in order to provide guidelines for the use of the DSM-5 Alternative Model for Personality Disorders with older adults.

Incremental Validity of Self- and Informant Report of Personality Disorders in Later Life.

Research shows moderate agreement between different sources of information when assessing personality disorders (PDs) in older adults. The differences between measurement methods appear to be not only the result of measurement error, but also an indication that each source holds nonredundant information relevant to PD diagnosis. The current article examines three sources of diagnostic information (self-report, informant report, and clinical interview) and the utility of these instruments in predicting important outcomes in older adulthood. We analyzed data from 1,630 adults between the ages of 55 and 64 years participating in a longitudinal study of later life. PD symptomatology was assessed using multiple methods, which were then used to predict health, marital satisfaction, and cognitive decline. All three sources contributed significantly to the prediction of these outcomes, with important implications for the assessment of older adults in research and clinical settings.
