EXPLORING RESILIENCE AND INDIVIDUAL DIFFERENCES
Title
EXPLORING RESILIENCE AND INDIVIDUAL DIFFERENCES.
Creator
Thorne, Robin, Mottarella, Karen, University of Central Florida
Abstract / Description
Few studies have investigated the relationships among resilience, optimism, and personality traits with U.S. college students; although some work has been done with Chinese university students. The current study explores the relationship between resilience, optimism and the Big Five personality traits. A sample of 251 undergraduate students completed the Connor-Davidson Resilience Scale (CD-RISC), the 9-item version of the Personal Optimism & Self-Efficacy Optimism Scale (POSE-E), and the NEO...

The current study explores the relationship between resilience, optimism and the Big Five personality traits. A sample of 251 undergraduate students completed the Connor-Davidson Resilience Scale (CD-RISC), the 9-item version of the Personal Optimism & Self-Efficacy Optimism Scale (POSE-E), and the NEO- Five Factor Inventory (NEO-FFI). Results indicate a significant positive relationship between resilience and optimism. The results also indicate positive significant relationships between resilience and extraversion, as well as resilience and conscientiousness. A significant negative significant relationship between resilience and neuroticism was found. The results of this study helpful identify characteristics of students who are at-risk following life stressors and traumas.

AN EXPLORATION OF CHRONIC PAIN EXPERIENCE, COPING, AND THE NEO FIVE FACTORS IN HIGH FUNCTIONING ADULTS

AN EXPLORATION OF CHRONIC PAIN EXPERIENCE, COPING, AND THE NEO FIVE FACTORS IN HIGH FUNCTIONING ADULTS.

Abstract / Description
Chronic pain affects nearly 48 million Americans (Haggard, Stowell, Bernstein, & Gatchel, 2008). Established guidelines for pain management encourage the use of personality assessment in chronic pain evaluation (Karlin, Creech, Grimes, Clark, Meagher, & Morey, 2005). In relation to the Big Five personality factors, low Openness relates negatively to treatment success, (Hopwood, Creech, Clark, Meagher, & Morey, 2008), and elevated Neuroticism scores also correlate with increased pain levels...
Show moreChronic pain affects nearly 48 million Americans (Haggard, Stowell, Bernstein, & Gatchel, 2008). Established guidelines for pain management encourage the use of personality assessment in chronic pain evaluation (Karlin, Creech, Grimes, Clark, Meagher, & Morey, 2005). In relation to the Big Five personality factors, low Openness relates negatively to treatment success, (Hopwood, Creech, Clark, Meagher, & Morey, 2008), and elevated Neuroticism scores also correlate with increased pain levels among individuals in hospital or rehab settings (Ashgari & Nicholas, 2006; Nitch & Boon, 2004). In contrast to these prior studies, this study identifies correlates in a relatively high-functioning population (college students) to further elucidate the connection between chronic pain and personality. This study compares scores on the NEO-FFI (Costa & McCrae, 1992), the West Haven-Yale Multidimensional Pain Inventory (WHYMPI, Kerns, Turk, & Rudy, 1985), and the Pain Catastrophizing Scale (PCS, American Academy of Orthopaedic Manual Physical Therapists, 2010). Significant correlations were found between Neuroticism, Extraversion, and Agreeableness and select subscales of both the WHYMPI and the PCS. A linear regression of scores showed that Neuroticism was very strongly related to WHYMPI scores. In fact, the WHYMPI scores accounted for 67.9% of variance in Neuroticism. Scores on the WHYMPI also correlated with PCS scores. Helplessness and Overall scores significantly correlated to Life Control and certain positive social support scores. The findings of this study emphasize the need for pain clinicians to incorporate psychological assessments, especially concerning Neuroticism, into their evaluations of chronic pain patients.

Detecting Threats from Constituent Parts: A Fuzzy Signal Detection Theory Analysis of Individual Differences

Detecting Threats from Constituent Parts: A Fuzzy Signal Detection Theory Analysis of Individual Differences.

Abstract / Description
Signal detection theory (SDT) provides a theoretical framework for describing performance on decision making tasks, and fuzzy signal detection theory (FSDT) extends this description to include tasks in which there are levels of uncertainty regarding the categorization of stimulus events. Specifically, FSDT can be used to quantify the degree to which an event is 'signal-like', i.e., the degree to which a stimulus event can be characterized by both signal and non-signal properties.

Show moreSignal detection theory (SDT) provides a theoretical framework for describing performance on decision making tasks, and fuzzy signal detection theory (FSDT) extends this description to include tasks in which there are levels of uncertainty regarding the categorization of stimulus events. Specifically, FSDT can be used to quantify the degree to which an event is 'signal-like', i.e., the degree to which a stimulus event can be characterized by both signal and non-signal properties. For instance, an improvised explosive device (IED) poses little threat when missing key elements of its assembly (a stimulus of low, but not zero, signal strength) whereas the threat is greater when all elements necessary to ignite the device are present (a stimulus of high signal strength). This research develops a link between key individual cognitive (i.e., spatial orientation and visualization) and personality (i.e., extroversion, conscientiousness, and neuroticism) differences among observers to performance on a fuzzy signal detection task, in which the items to be detected (IEDs) are presented in various states of assembly. That is, this research relates individual difference measures to task performance, uses FSDT in target detection, and provides application of the theory to vigilance tasks. In two experiments, participants viewed pictures of IEDs, not all of which are assembled or include key components, and categorize them using a fuzzy rating scale (no threat, low threat potential, moderate threat potential, or definite threat). In both experiments, there were significant interactions between the stimulus threat level category and the variability of images within each category. The results of the first experiment indicated that spatial and mechanical ability were stronger predictors of performance when the signal was ambiguous than when individuals viewed stimuli in which the signal was fully absent or fully present (and, thus, less ambiguous). The second study showed that the length of time a stimulus is viewed is greatest when the signal strength is low and there is ambiguity regarding the threat level of the stimulus. In addition, response times were substantially longer in study 2 than in study 1, although patterns of performance accuracy, as measured by the sensitivity index d', were similar across the two experiments. Together, the experiments indicate that individuals take longer to evaluate a potential threat as less critical, than to identify either an absence of threat or a high degree of threat and that spatial and mechanical ability assist decision making when the threat level is unclear. These results can be used to increase the efficiency of employees working in threat-detection positions, such as luggage screeners, provides an exemplar of use of FSDT, and contributes to the understanding of human decision making.
