Show moreThe current dismounted soldier and the soldier of the future will be loaded' with more information processing tasks while they perform shooting tasks. It is conceivable that some increased level of cognitive tasking may be performed simultaneously with required shooting tasks. The effect of cognitive load on shooting performance has been previously examined (Scribner and Harper, 2001). This study concentrated on the effect of various cognitive workload demands on a friend-foe discrimination shooting task in a single- and dual-task scenario. In light of this, it is imperative that the soldier not be overburdened mentally, which may result in decreased survivability and lethality. Specifically, this study was designed to examine the ability of the soldier to perform friend-foe target discrimination and shooting accuracy, with varying target exposure times, friendly target signatures, and varying cognitive load demands (working memory recall task). Using the Small Arms Simulator Testbed (SAST) we examined the effects of manipulations of working memory load and sustained information transfer, on shooting performance (as measured by target acquisition and friend/foe discrimination indices). Additionally, we investigated subjective measures of workload and stress. A secondary task, administered aurally, was given to subjects to attend to while they performed shooting (friend/foe discrimination task) scenarios: working memory recall task. Each type of task consisted of three levels of difficulty. Analysis of variance revealed significant differences for the memory recall task during shooting and non-shooting conditions. Furthermore, results showed that workload increased as a function of task demand, with associated decreases in shooting performance.

In multimedia learning environments, research suggests that simultaneous presentation of redundant text (i.e. identical narration and on-screen text) may inhibit learning when presented with animation at the same time. However, related studies are limited to testing with cause-and-effects content information (e.g., Moreno & Mayer, 1999, 2002).

Show moreIn multimedia learning environments, research suggests that simultaneous presentation of redundant text (i.e. identical narration and on-screen text) may inhibit learning when presented with animation at the same time. However, related studies are limited to testing with cause-and-effects content information (e.g., Moreno & Mayer, 1999, 2002). This study examined the effects of redundant text on learners' memory achievement and problem solving ability. The study replicated and extended prior research by using descriptive, rather than cause-and-effect content information. The primary research questions were (a) does redundant text improve learning performance if learners are presented with instructional material that addresses subject matter other than cause-and-effect relationship? and (b) does sequential presentation of animation followed by redundant text help learning? To answer the research questions, five hypotheses were tested with a sample of 224 Taiwanese students enrolled in a college level Management Information System (MIS) courses at a management college in southern Taiwan. Statistically significant differences were found in memory achievement and problem solving test scores between simultaneous and sequential groups; while no statistically significant differences were found in memory achievement and problem solving test scores between verbal redundant and non-redundant groups. These results were supported by interviewees expressing difficulty in connecting animation and verbal explanation in the two sequential presentation groups. The interview responses also helped to explain why insignificant results were obtained when redundant and non-redundant verbal explanations with animation were presented simultaneously. In general, the results support previous research on the contiguity principle, suggesting that sequential presentations may lead to lower learning performance when animation and verbal explanation are closely related. The separation of the two types of information may increase cognitive load. In addition, the study found that impairment of redundant text was also affected by various learning characteristics, such as the structure of the instructional content and learners previous learning experiences. Recommendations for future study include: (a) research on various situations such as characteristics of the content, characteristics of learners, and difficulty of the instructional material that influences the effects of redundant text, and (b) research on prior learning experience that influences the effects of simultaneous redundant text presentations.

Show moreDevelopers of Commercial off the Shelf (COTS) gaming software are making remarkable strides in increasing the realism of their software. This realism has caught the attention of the training community, which has traditionally sought system and operational replication in training systems such as flight simulators. Since games are designed and marketed for entertainment and not designed for training of tasks, questions exist about the effectiveness of games as a training system in achieving the desired transfer of skills to the actual environment. Numerous studies over the past ten years have documented that PC-based simulation training environments can offer effective training for certain types of training, especially aircraft piloting tasks. Desktop games have been evaluated from a case study approach for use in aviation training (Proctor, et al., 2004) and education planning and evaluating small unit tactics) (Proctor, et al., 2002) with positive results. Based on the review of selected studies in this area, PC-based simulator platforms have been found to have a positive training impact on cognitive skills (as opposed to psycho-motor skills). Specifically, the literature review has identified that skill sets involved in team resource management, intra- and inter-team coordination, and tactical team maneuvers have been shown to benefit from the use of PC-based simulation training. The purpose of this research was to evaluate the training transfer associated with a Tactical Decision-making game, using Close Combat: First to Fight as a case study. The null hypothesis tested was that traditional field training is equivalent to virtual training combined with field training. Measurements of the subjects' performance in live training were recorded. Additionally, self assessment questionnaires were administered.

Show moreThe Internet is becoming the main source for various tasks, from learning, to working, and shopping. There are many websites one can use to shop. Almost all stores have a website from which you can order anything you might want. As online shopping becomes more prominent, it is important to understand the effects of the Internet and its product reviewers and, specific to this study, consumer decision making. This study seeks to understand the effect of star ratings and valence on review perception between the different cognitive levels of individuals. Recognition review perception, and intent to purchase were being measured. Results showed that need for cognition did have an effect on accuracy of recognition and perceived valence. Need for cognition and congruency as well as actual valence had an effect on perceived valence. Need for cognition, actual valence, and congruency all had an effect on purchase intention. This research is important because it is relevant to a growing trend around the world. Technology is already integrated into nearly everyone's lives and it is only going to more so as we continue to evolve. Just as it is becoming more common for people to receive education from online institutions, and for employers to use more Internet based applications, it is only natural consumers will continue the trend of purchasing items online. Learning the social and cognitive influences of online reviews on perception and purchasing intentions is something everyone needs to be aware of.

Show moreArt can be an elusive concept. Neither an outsider nor a professional artist is immune to abstractions in the attempt to describe it. Every individual must necessarily come from their own, unique perspective. The obstacles that we experience in defining the essence of art can be better understood if we see them as a gauge for our historical period. Given the limits of our contemporary conditions, it seems impossible that we may ever overcome the vast chasms that imprison us. We are discouraged to build bridges, at almost every turn, by the suggestive hopelessness of the abysmal distances between us. The series of work that I have developed for this thesis is a reflection on limitations. Whether we find them in the creative process or within the simple contemplations of our life experiences, thinking on our limits can lead us to a heightened cognition where we may find a lofty expression of human freedom. If art is to have a proper role in human culture, human individuals must begin to solve the problems of our limitations through the freedom that cognition affords us. We can begin by thinking imaginatively. Although difficult, it is quite possible to imagine reality. Beyond the mere production of beautiful objects, art is the very current that warms human beings to the reality that surrounds us. Artists can become involved by attempting to immerse their life in a new light of knowledge. With this sentiment, inspiration can begin offering us flight towards unreachable heights. The path that leads us, then, to an authentic concept of art will also take us into the world of another just as elusive: spirit.

Show moreIn this thesis, a literature review was conducted in order to analyze the numerous sources that investigated the effects memory games may have on participants. Each study covered different scopes and methods in the field of cognitive improvement, which gave way to a variety of results used to create a comprehensive literature review. The experiments included in the literature review gathered evidence to find the effect that "brain" games had on memory and cognitive skills. An explanation and analysis were made on the brain's deterioration as it ages and the varying amounts of plasticity it contains. The overall perspective gained from the literature review allowed for a better understanding of the results of the surveys conducted for this thesis. The distinctive ways to encourage and improve brain health were researched, and a particular focus was placed on memory games regarding brain health factors. Overall, the benefits identified covered an increase in working memory, skills, and processing speed. However, there was an indication that the improvements were only for the tasks at hand. When research was conducted on transferable activities, there was little to no proof of the transferability of measured improvements. During the research portion of the thesis, a survey was conducted that involved 90 participants from the age of 60 and older on their perception of brain games. The results of the 9-question survey showed statistically significant correlations between the amount of times individuals had played memory games and their perception of both the simplicity and effectiveness of these games. Participants who had played games more frequently viewed the games as both more effective and simpler. Similarly, participants with more education perceived the games as being simpler. The male participants in this study were found to play memory games more frequently than the women. Overall, the correlations drawn from the results of the survey promote the enriched discussion on the subject of memory games and cognitive improvement.

Evidence suggests that providing these captions can benefit Deaf and Hard of Hearing populations and also that concise, textual representations of information increase retention for average learners in multimedia settings. Individual differences were considered and low internal control participants did significantly better on exams when material was captioned compared to when it was not. They also tended to outperform high internal control participants on captioned material exams.

Show moreEnsuring effectiveness of training programs has been a dominant theme in the training industry, and is constantly evolving with the steady incorporation of emerging technology. This field study offers an investigation into the intersection between the applied and research world, and examines the practicality of recommended best practices for implementing synthetic learning environments (SLEs) in the military. Specifically, cognitive load has been identified as a significant factor in influencing the effectiveness of training programs. Research on this topic has focused on utilizing the affordances of SLEs to decrease cognitive load imposed by the material and system in order to allow for more cognitive resources to be allocated towards schema construction and automation. Therefore, this study was derived from a need to ensure that the introduction of SLEs into training programs did not hinder learning or training transfer by comparing the performance outcome measures from two SLEs, Virtual BattleSpace 3 (VBS3) and the Military OpenSimulator Enterprise Strategy (MOSES). Based on concepts of cognitive load, it was possible that any group differences could be explained by the varying levels of cognitive load imposed by either system. Furthermore, the specific system could influence the strength of the effect of cognitive load on performance measures. A conditional process analysis model was constructed from the theorized relationships, and the bootstrap method was used to analyze the model. Research findings indicated no support, and discussions delved into possible explanations for results of the study, limitations, and recommendations for future research. While the analyses were nonsignificant, this was the first study investigating the difference between the VBS3 and MOSES platform, and indicated no difference in impacting performance. Additionally, because MOSES is a free, open source platform, this study could support industries that are looking for cost-effective methods to expand training programs in the direction of SLEs.

Show moreMultiteam systems are an integral part of our daily lives. We witness these entities in natural disaster responses teams, such as the PB Oil Spill and Hurricane Katrina, governmental agencies, such as the CIA and FBI, working behind the scenes to preemptively disarm terrorist attacks, within branches of the Armed Forces, within our organizations, and in science teams aiming to find a cure for cancer (Goodwin, Essens, (&) Smith, 2012; Marks (&) Luvison, 2012). Two key features of the collaborative efforts of multiteam systems are the exchange of information both within and across component team boundaries as well as the virtual tools employed to transfer information between teams (Keyton, Ford, (&) Smith, 2012; Zaccaro, Marks, (&) DeChurch, 2012).The goal of this dissertation was to shed light on enabling the effectiveness of multiteam systems. One means of targeting this concern was to provide insight on the underpinnings of MTS mechanism and how they evolve. The past 20 years of research on teams supports the central role of motivational and affective states (Kozlowski (&) Ilgen, 2006; and Mathieu, Maynard, Rapp, (&) Gibson, 2008) as critical drivers of performance. Therefore it was my interest to understand how these critical team mechanisms unravel at the multiteam system level and understanding how they influence the development of other important multiteam system processes and emergent states. Specifically, this dissertation focused on the influence motivational and affective emergent states (such as multiteam efficacy and multiteam trust) have on shaping behavioral processes (such as information sharing-unique and open) and cognitive emergent states (such as Transactive memory systems and shared mental models). Findings from this dissertation suggest that multiteam efficacy is a driver of open information sharing in multiteam systems and both types of cognitive emergent states (transactive memory systems and shared mental models). Multiteam trust was also found to be a critical driver of open information sharing and the cognitive emergent state transactive memory systems.Understanding that these mechanisms do not evolve in isolation, it was my interest to study them under a growing contextual state that is continuously infiltrating our work lives today, under virtual collaboration. This dissertation sought to uncover how the use of distinct forms of virtual tools, media rich tools and media retrievability tools, enable multiteam systems to develop needed behavioral processes and cognitive emergent states. Findings suggest that the use of media retrievability tools interacted with the task mental models in promoting the exchange of unique information both between and within component teams of a multiteam system.The implications of these findings are twofold. First, since both motivational and affective emergent states of members within multiteam systems are critical drivers of behavioral processes, cognitive emergent states, and in turn multiteam system performance; future research should explore how we can diagnose as well as target the development of multiteam system level efficacy and trust. Second, the virtual communication tools that provide multiteam systems members the ability to review discussed materials at a later point in time are critical for sharing information both within and across component teams depending on the level of shared cognition that multiteam system members possess of the task.Therefore the ability to encourage the use and provide such tools for collaborative purposes is beneficial for the successful collaboration of multiteam systems.

Show moreThis dissertation comprises three studies, one qualitative and two experimental, that center on auditor's use of data analytics. Data analytics hold the potential for auditors to reallocate time spent on labor intensive tasks to judgment intensive tasks (Brown-Liburd et al. 2015), ultimately improving audit quality (Raphael 2017). Yet the availability of these tools does not guarantee that auditors will incorporate the data analytics into their judgments (Davis et al. 1989; Venkatesh et al. 2003). The first study investigates implications of using data analytics to structure the audit process for nonprofessionalized auditors. As the public accounting profession continues down a path of de-professionalization (Dirsmith et al. 2015), data analytics may increasingly be used as a control mechanism for guiding nonprofessionalized auditors' work tasks. Results of this study highlight negative ramifications of using nonprofessionalized auditors in a critical audit setting. The second study examines how different types of data analytics impact auditors' judgments. This study demonstrates the joint impact that the type of data analytical model and type of data analyzed have on auditors' judgments. This study contributes to the literature and practice by demonstrating that data analytics do not uniformly impact auditors' judgments. The third study examines how auditors' reliance on data analytics is impacted by the presentation source and level of risk identified. This study provide insights into the effectiveness of public accounting firms' development of data scientist groups to incorporate the data analytic skillset into audit teams.Collectively, these studies contribute to the literature by providing evidence on auditors' use of data analytics. Currently, the literature is limited to demonstrating that auditors are not effective at identifying patterns in data analytics visualizations when viewed before traditional audit evidence (Rose et al. 2017). The three studies in this dissertation highlight that not all data analytics influence judgments equally.

Show moreMultiple object tracking (MOT) is a cognitive process that involves the active processing of dynamic visual information. In athletes, MOT speed is critical for maintaining spatial awareness of teammates, opponents, and the ball while moving at high velocities during a match. Understanding how MOT speed changes throughout the course of a competitive game may enhance strategies for maintaining optimal player performance. The objective of this study was to examine changes in MOT speed and running performance during a 90-minute intermittent soccer performance test (iSPT). A secondary purpose was to examine the relationship between aerobic capacity and changes in MOT speed.Seven competitive female soccer players age: 20.4 (&)#177; 1.8 y, height: 166.7 (&)#177; 3.2 cm, weight: 62.4 (&)#177; 4.0 kg, VO2max: 45.8 (&)#177; 4.6 ml/kg/min-1) completed an intermittent soccer performance test (iSPT) on a Curve(TM) non-motorized treadmill (cNMT). The iSPT was divided into two 45-minute halves with a 15-minute halftime [HT] interval, and consisted of six individualized velocity zones. Velocity zones were consistent with previous time motion analyses of competitive soccer matches and based upon individual peak sprint speeds (PSS) as follows: standing (0% PSS, 17.8% of iSPT), walking (20% PSS, 36.4% of iSPT), jogging (35% PSS, 24.0% of iSPT), running (50% PSS, 11.6% of iSPT), fast running (60% PSS, 3.6% of iSPT), and sprinting (80% PSS, 6.7% of iSPT). Stand, walk, jog and run zones were combined to create a low-speed zone (LS). Fast run and sprint zones were combined to create a high-speed zone (HS). MOT speed was assessed at baseline (0 min.) and three times during each half of the iSPT. Dependent t-tests and Pearson correlation coefficients were utilized to analyze the data. Across 15-minute time blocks, significant decreases in distance covered and average speed were noted for jogging, sprinting, low-speed running, high-speed running, and total distance (p's (<) 0.05). Players covered significantly less total distance during the second half compared to the first (p = 0.025). Additionally, significant decreases in distance covered and average speed were observed during the second half for the sprint and HS zones (p's ? 0.008). No significant main effect was noted for MOT speed across 15-minute time blocks. A trend towards a decrease in MOT speed was observed between halves (p = 0.056). A significant correlation was observed between the change in MOT speed and VO2max (r = 0.888, p = 0.007). The fatigue associated with 90 minutes of soccer specific running negatively influenced running performance during the second half. However, increased aerobic capacity appears to be associated with an attenuation of cognitive decline during 90-minutes of soccer specific running. Results of this study indicate the importance of aerobic capacity on maintaining spatial awareness during a match.

Standardized assessment scores of cognitive and linguistic evaluations were collected and correlated to features of macrolinguistic discourse analysis.Participants with acquired communication disorders performed best on the story retell discourse task compared to single picture description and sequential picture description. Significant measures for story retell task include lexical efficiency, time efficiency, and Main Concept score. No significant difference was found on performance between single-picture description task and sequential picture description for participants with acquired communication disorders. The Main Concept Analysis presented with the strongest correlation to macrolinguistic features of analysis. These preliminary findings suggest that main concept score is a predominant indicator of the overall informativeness and macrostructure of a speaker's discourse.

Show moreThis dissertation consists of three studies investigating the relationship between business analytics and decision making in accounting. In an effort to improve performance, organizations increasingly emphasize fact-based decision making supported by business analytics, which translate complex data into manageable information through statistical analysis. While the recent focus on business analytics is transforming how managers make decisions, analytics alone do not generate increased performance; the synergy between business analytics and user judgments is a vital component of realizing value. To this end, Study I experimentally investigates how various characteristics of business analytics affect individuals' reliance and perceptions of the analytic. Through the lens of cognitive fit a 2(&)#215;2 between-subjects experiment is conducted examining business analytics effects of input and process attributes on users' reliance. Cognitive fit theory posits that effective problem solving depends on the match between the technology and the decision process. The second study investigates the impact of management interventions (i.e. actions influencing adoption) toward improving reliance on business analytics. From an organizational perspective, an important concern for management is promoting greater employee acceptance and utilization of business analytics. Building on the Technology Acceptance Model, Study II experimentally examines the effect of management support and consensus of multiple analytics on increasing reliance and on participants' evaluation of the business analytic. Study III further explores the relationship between characteristics of business analytics and the decision maker by developing a theoretical model regarding the effects of perceived decision similarities between the user and the business analytic on users' perceived usefulness. Overall, the results reported in this dissertation suggest that 1) characteristics of business analytics influence users' judgments and decision making, 2) management can take actions to influence the relationship between users and business analytics, and 3) users are likely to evaluate their cognitive similarity to these business analytics, and these perceptions influence perceived usefulness of the business analytics.

Show moreThese two companion studies theoretically and empirically examine managers' use of different cognitive frames in decision-making related to corporate sustainability. Study I is a theoretical undertaking aimed at highlighting potential zones of investigation arising from the introduction of paradox theory into managerial accounting. First, I examine extant literature on paradoxes to garner an understanding of its evolution and application in the management and psychology domains. Second, I use current constructs and typologies to identify multiple sustainability and managerial accounting tensions as paradoxical. Third, I make recommendations on how to apply paradox theory more effectively to the corporate sustainability tensions I identified. I conclude the first paper with research questions pertaining to managerial accounting in corporate sustainability. Study II is a behavioral experiment. In this study I examine the effects of business case and paradoxical case cognition on managers and seek to uncover which organizational performance measures better support each cognition. Scholars suggest that the tensions in corporate sustainability arise from the complicated and interdependent relationship among its dimensions. and oftentimes progress towards any single dimension, might have unintended consequences on the other dimensions Hence, the empirical question becomes, amid such tensions, how do managers make decisions that are not solely driven by the financial dimension of corporate sustainability? Applying paradox theory, with its emphasis on acknowledging and working through tensions, holds the potential to elucidate how managers can further explore the tensions inherent in management accounting and sustainability. Study II results show that managers operating in a paradoxical case cognition with broad performance measures made more sustainable decisions relative to their counterparts operating in a business case cognition with narrow performance measures. Together these companion studies generally support the use of paradox theory in studying sustainability decision-making and its use in moving beyond short-term economically focused organizational processes.

Show moreAt the present time, most systems engineers do not have access to cognitivework analysis information or training in terms they can understand. This may lead to adisregard of the cognitive aspect of system design. The impact of this issue is systemrequirements that do not account for the cognitive strengths and limitations of users.Systems engineers cannot design effective decision support systems without definingcognitive work requirements. In order to improve system requirements, integration ofcognitive work requirements into the systems engineering process has to be improved.One option to address this gap is the development of a Cognitive Work Analysis (CWA)framework using Systems Modeling Language (SysML). The study had two phases.The first involved aligning the CWA terminology with the SysML to produce a CWAframework using SysML. The second was the creation of an instruction using SysML toinform systems engineers of the process of integrating cognitive work requirements intothe systems engineering process. This methodology provides a structured framework todefine, manage, organize, and model cognitive work requirements. Additionally, itprovides a tool for systems engineers to use in system design which supports a user'scognitive functions, such as situational awareness, problem solving, and decisionmaking.

Show moreThe method of instruction and the formal curriculum within two Kenyan teacher training colleges were studied in order to discover which messages regarding pedagogical practice are internalized within novice Kenyan primary school teachers and then actualized within their classrooms. An educational connoisseurship approach was utilized to give descriptive, interpretive, evaluative, and thematic insight. Three data streams were collected through interview, observation, and design evaluation in order to establish structural corroboration and internal validity. The study found that the method of instruction by the teacher training college faculty was teacher-centered and utilized lower order cognitive methodology. Though the formal curriculum design was strong, it too promoted lower cognitive processes. These two messages, teacher-centered pedagogies and lower cognitive processes, are being internalized and applied by the novice teachers and maybe affecting the quality of education in Kenyan schools. The results of this study suggest that pedagogical skills promoting higher cognitive levels should be developed through in-service training in Kenyan training colleges and primary schools as a way to improve the quality of education in this country.

Show moreThe aim of the current study was to investigate the way teen pregnancy is portrayed in Seasons 1 and 2 of the television drama The Secret Life of the American Teenager. Framing theory and social cognitive theory were used as guiding frameworks for exploring the way the main character's pregnancy was presented and the way this presentation may influence the ideas and behaviors of viewers. A qualitative content analysis was conducted to examine portrayals in the first 23 episodes. Results indicated that teen pregnancy was portrayed in five major ways: as Dramatic, as Identity, as Manageable, as Transformative, and as Serious. Overall, the findings suggest that teen pregnancy was presented in ways that encourage viewers to perceive this issue as positive and negative, with clearly positive outcomes.

Show moreThe intent of this concurrent mixed method study was to examine teacher perceptions and student applications of cognitive reading comprehension strategy use as applied to the reading and interpretation of a mathematics word problem. Teachers' perceptions of the relevance and application of cognitive reading comprehension strategies to mathematics contexts were investigated through survey methods. Additionally, students' cognitive strategy use was explored by eliciting verbalization of cognition using think aloud protocol and clinical interview probes with purposively selected first through sixth-grade students. An experimental component of this study involved the random assignment of teachers to a professional development book study focused on either a) instructional methods supportive of integrated cognitive strategy instruction in reading and mathematics (treatment group) or b) a review of cognitive strategy instruction in reading (control group). The results of this study indicate that the elementary student participants did not recognize the cognitive comprehension strategies that they were using during the initial reading of the mathematical text as relevant to mathematics based text, which is why initial patterns of strategy use were not sustained or renegotiated, but were instead replaced or extinguished without replacement upon identification of the text as mathematical. This may be due to a lack of: 1) domain-general instruction, 2) varied text examples in their schooling, and/or 3) conditional knowledge instruction for strategy use, effects that may be caused by the students' teachers' own domain-specific perceptions of cognitive strategy use at the elementary level. The teachers in the treatment group demonstrated greater awareness of the relevance of cognitive reading comprehension strategies for mathematics text than the control group; however, there was no evidence that this new awareness impacted their instruction in this study. Implications for professional development, integrated cognitive strategy instruction, and contributions to existing literature are discussed.

Show moreProblem: Heart failure is the most frequent cause for hospital readmissions in Medicare recipients, with an estimated annual cost of $12 billion. Heart failure hospitalizations are also an independent risk factor for increased mortality. Self-care, thought to be enhanced by perceived social support, is key to managing this syndrome, and up to 50% of readmissions are considered the result of inadequate self-care.Purpose: To evaluate perceived social support and self-care characteristics of patients hospitalized with an exacerbation of heart failure, and to compare these characteristics with a study of ambulatory patients with heart failure. In addition, to assess the relationship between perceived social support and self-care.Methods: This was a multi-site descriptive comparative study. Following informed consent, participants were screened for sufficient cognition to consent. Patients were then administered the Medical Outcome Study-Social Support emotional/informational subscale, and the three Self-Care of Heart Failure Index subscales. Two-sample t tests and multiple regression were utilized to analyze the data. Results were compared with a sample of community-dwelling heart failure patients in another study.Results: Of 161 consented patients 121 passed the cognition screening and were included in the study. Average age was 71 years; gender and type of heart failure was evenly split. Mean Charlson Comorbidity Score was 7.43, and the mean six month number of hospitalizations was 2.43. Approximately 31% of participants were African American. Both perceived social support (t=-4.007, df=211, p(<).001) and self-care maintenance (t=-3.343, df=220, p(<).002) scores were lower in the hospitalized participants than the comparison group of community dwellers. Perceived social support was associated with self-care confidence (?=.210, t=-2.210, p(<).029), but not self-care maintenance or self-care management. Forty-six percent of participants scored higher than the 70% cut point for adequate self-care confidence, which was 1.4 times higher than in the community participants. Self-care confidence was also related to self-care maintenance (?=.388, t=4.676, p(<).001) and self-care management (?=.327, t=3.793, p(<).001).Conclusions: Results have implications for facilitating self-care knowledge and skills in heart failure patients. Patient education during hospitalization may not be the ideal timing to promote understanding and retention. Interventions to enhance self-care confidence may assist patients to develop self-care skills more than current teaching techniques. Because cognitive deficiencies were found in 25% of pre-screened participants for this study, further research is recommended to determine if hospitalized patients have transient cognitive issues or if cognitive impairments are more prevalent in all heart failure patients.
