An individual’s personality traits and characteristics have been found to have an important relationship with health behaviors. However, there has been minimal research conducted with personality types. The purpose of the study was to examine the predictive relationship among MBTI® personality preferences and types and both selected health-promoting and selected risk-taking behaviors among residential college students. Furthermore, several potential mediating demographic variables were added to the study to determine their predictive relationship and if they should be entered into a model for the selected health behaviors. The study used a cross-sectional design with two self-report instruments and demographic questionnaire. The two self-report instruments were the MBTI® and the HPLP II. A systematic random sample was employed to obtain the sample of full-time residential college students. A total of 406 subjects voluntarily completed the instruments. The subjects ranged in age from 18 to 28 with 98.3% reporting traditional college age. Descriptive and inferential statistics with an alpha level of .05 were used for data analysis. The results revealed that models incorporating MBTI® personality preferences and types had a significant predictive relationship with nutrition, interpersonal relations, spiritual growth, physical activity, aggregate health-promoting lifestyle, alcohol use, binge drinking, and heavy drinking. However, the variance explained by the models for each behavior was consistently low with the one exception of interpersonal relations. Health-responsibility, stress management, and cigarette smoking could not be predicted by models integrating MBTI® personality preferences and types. Nonetheless, specific personality preferences and types did have a significant relationship with health-responsibility, stress management, and cigarette smoking. In conclusion, MBTI® personality preferences and types provided valuable insight into explaining several of the selected health behaviors. The results revealed personality preferences and type can be useful in health research. Given the popularity of the MBTI®, future research incorporating the MBTI® and various health behaviors may offer valuable information used by health professionals and counselors to modify health behaviors.

This study suggests that it is possible to classify websites as either extrovert or introvert and logical or emotional in style, impact and appearance. Both the extraversion/ introversion and logical/emotional dichotomies are major descriptors in the character typology devised by C.G. Jung and extended by others. Apart from the dichotomies mentioned above, Jung’s typology also makes use of various emotional characteristics of human beings as descriptors of temperament or character. The study suggests that it is useful to identify websites in terms of the descriptors that Jung and others propose, and that different websites will display various “temperamental” differences that are as important for website design as is a clear understanding of the temperaments of its target users. By taking account of the most common temperamental differences in websites, it should be possible to maximise the efficiency and appearance of different kinds of websites such as those created for government agencies, banks, online shopping, social networking and search engines. / Dissertation (MIT)--University of Pretoria, 2008. / Informatics / unrestricted

The aim of this paper is to analyse gamification practices as well as to study management by personalities. Upon this basis the objective will be to design a management software for the new management era that will collect large quantities of data about individual team members (Big Data-based software), thus enabling managers to allocate new team members onto teams upon their personalities, skills and experience in gamified user interface. The ultimate goal of this paper will be to serve as guidebook for managers to manage by knowing the variety of personalities as well as by applying gamification elements onto everyday tasks.

This study was designed to examine two questions. First, does increasing Myers-Briggs Type similarity correlate with improved performance by counselor supervisor/supervisee dyads? Second, is the Communication Style Adjustment Index superior to the cognitive style scale matching procedure as a method of quantifying MBTI similarity in dyads? Sixty-eight supervisor/supervisee dyads were recruited from University of North Texas Counselor Education Master's level practicum classes. Supervisee class rankings and supervisor performance ratings were correlated with the dyads' MBTI similarity as measured by the Communication Style Adjustment Index and the cognitive style matching procedure. While none of the hypotheses were supported it was noted that there was interaction approaching significance between dyadic similarity using the Communication Style Adjustment Index and supervisor performance ratings.

Written communication is an integral part of any organisation regardless of size or the nature of its business. The writer chooses words that should be understood by the readers. However, these words have been chosen based on a variety of factors, one of which is personality type, and the writer's personality type may differ from that of the readers. The research question underpinning this study is - In what ways, if at all, do personality types (as determined by the Myers-Briggs Type Indicator (MBTI) and most frequently found in management positions), select and use different words and phrases when writing business communication? To investigate this question, the psychological type theory of Jung, the personality type theory of Briggs and Myers, and organisational communication theory are applied. The methodology used is descriptive research with the documents analysed using content analysis, employing NUD.IST Vivo in conjunction with manual assessment. The research findings confirm that each personality type does use different words, validating personality type theory and therefore, making a contribution to the expanding body of research in this field. The knowledge gained from this study has significance in areas related to organisations as well as education and communication theory.

Personality of software engineering professionals has been a continuous element of interest in academic research. Researchers have applied different models of personality analysis in various software engineering areas to identify improvement points, to promote job satisfaction and to better organize teams. Among these models, we can highlight the MBTI and BIG Five. This work aims to conduct a study to evaluate personality models applied in software engineering and to understand how human personality influences software quality. Two controlled experiments were performed, the first in industry, in IT department of a private higher education institution and the second in an advanced programming discipline in academy. For both experiments, the quality of software individually produced by each participant was evaluated using software metrics for object-oriented paradigm languages. As a result, there is evidence that developers with different personalities do not develop software of equal quality. As the experiments were run in a single geographic location with an own software development culture, additional studies need to be performed to determine any real link between personality and software quality. / A personalidade dos profissionais de engenharia de software tem sido um elemento contínuo de interesse na pesquisa acadêmica. Os pesquisadores aplicaram diferentes modelos de análise de personalidade em várias áreas de engenharia de software para identificar pontos de melhoria, promover a satisfação no trabalho e organizar melhor as equipes. Entre esses modelos destacamos o MBTI e BIG Five. Esta dissertação objetiva realizar um estudo para avaliar modelos de personalidade aplicados em engenharia de software e compreender como a personalidade humana influencia a qualidade do software. Dois experimentos controlados foram realizados, o primeiro na indústria, no departamento de TI de uma instituição privada de ensino superior e o segundo em uma disciplina de programação avançada na academia. Para ambas as experiências, a qualidade do software produzido individualmente por cada participante foi avaliada utilizando métricas de software para linguagens de paradigma orientadas a objetos. Como resultado, há evidências de que desenvolvedores com personalidades diferentes não desenvolvem software de qualidade igual. Como os experimentos foram realizados em uma única localização geográfica com uma cultura de desenvolvimento de software própria, estudos adicionais precisam ser realizados para determinar qualquer ligação real entre personalidade e qualidade de software.

運動依從性在健康管理議題裡是非常重要的一環，現在的人經常感到身體不適而診斷結果卻正常，這種現象根據世界衛生組織的定義為「亞健康」或「健康的灰色地帶」。在高壓的工作環境或不正常的生活作息下，最容易有這些徵狀，儘管大家都知道長期規律的運動可以促進健康，實際實行的狀況卻不如預期的好。為了改善此狀況，本研究透過蘋果公司的套件(ResearchKit)開發行動應用程式來幫助使用者增加運動依從性。此套件內建許多模組供開發者與研究人員使用，如聲明宣告與問卷模組等，讓整個研究、開發流程更為快速有效。本研究流程遵行設計科學方法論來創造一個設計實體，即為本研究開發的應用程式「Active Track」。 在設計階段，本研究採用了「說服設計準則」中的「Tailoring」與「Reminder」設計方法，意圖強化、形塑甚或改變使用者對於目標行為的態度，透過本應用程式來激勵使用者改變自身行為，達到目標設定。目前市面上許多健康管理的應用程式皆已證實個性與說服科技之間的相關性，因此本研究採用了MBTI適性分析工具並設計出相對應的激勵文字訊息，期望透過此設計實體來協助使用者增加運動依從性。 在第一階段的實驗評估，我們於166個下載人次當中篩選出87個有效樣本來比較樣本之間的表現，其中有54人有接收激勵文字訊息，33人則無。平均而言，那些有收到激勵文字訊息的受測者，完成率較沒有收到激勵文字訊息的受試者高出百分之十五。然而在訊息類型與個性是否相符的比較實驗當中，訊息符合與不符合使用者個性的結果之間並無顯著差異。本研究之結果僅顯示出透過激勵文字訊息可以有效督促使用者完成運動目標。在第二階段的實驗中加入了「訊息重複性」、「回饋機制」因子來改良應用程式，研究結果顯示訊息的重複整體而言可以提升百分之二十三的完成率，其中適性結果為「理性」的受測者則有百分之二十七的提升，然而回饋機制設計在本研究並無統計顯著。 在兩階段的設計循環下，本研究證實透過Active Track重複地傳送激勵文字訊息可以協助使用者增加運動依從性，進而降低罹患疾病的風險，研究結果對於未來說服系統之開發以及其他醫療領域提升依從性之相關研究也提供了良好的參考價值。 / Adherence to an exercise schedule is valuable for health management. Nowadays, most people have experienced uncomfortable feelings but diagnostic data are normal. The phenomenon is called ‘sub-health’ condition, which is a state between health and disease. People are likely to experience discomfort if their working environment is stressful and their lifestyle is unhealthy. Therefore, a long period of commitment to adhere to physical activity programs is beneficial for people’s health. Although people would benefit from support to increase exercise compliance, adherence to physical activity plans is often very low. To address these shortcomings, this paper introduces a low-cost method–an iOS application developed using Apple Inc.’s ResearchKit–to help people adhere to their physical activity plans. ResearchKit provides various modules such as consent declaration and survey task for helping researchers create a research app more efficiently. We applied design science methodology to create a design artifact, namely Active Track. By including the “Tailoring” and the “Reminder” persuasive principles in Active Track to develop, strengthen, or change attitudes or behaviors, the design artifact can act as support instruments that stimulate and encourage users to comply with target behavior. Because studies of health-promotion apps have identified the correlations between personality and persuasive technology, we used the Myer–Briggs Type Indicator personality assessment to design motivational messages for each type of personality as a text reminder in Active Track. In the first evaluation stage of Active Track, we identified 87 valid participants (54 with motivational messages and 33 without motivational messages) from 166 downloads for performance comparison. On average, the completion rates of participants who were presented with motivational messages were 15% higher, but the difference in message matching experiment was not significant. The results demonstrated that our design approach is able to improve adherence on exercise plans by providing users with motivated messages. Therefore, we implemented repetitiveness and feedback intervention in a further design iteration and evaluated the improvement in Active Track by using these two new factors. The results showed that the repetitiveness factor enhanced the completion rate by approximately 23%; in particular, participants who were identified as having Thinking-type MBTI personalities exhibited an improvement of approximately 27% due to repetitive messages. However, feedback information had no significant effect on adherence. In summary, the findings of this study confirmed that Active Track can help individuals to improve their exercise adherence through repetitive motivational messages, reduce the risk of diseases, and provide useful insights for the future development of persuasive systems and studies into adherence enhancement for health care.

My dissertation is focused on analysing the importance of personality typology during the choice of career. The theoretical part is aimed at the clarification of related key concepts, summary of knowledge concerning the personality typology and explanation of chosen theories dealing with personality typology. I paid particular attention to the type indicator MBTI, which is subsequently used in the practical part. The methodological part follows the theoretical part. The methodological part delimits the particular phases of the research and together with the theoretical part serves as a basis for the practical part. Within the practical part the personality typology issues used during the choice of career are analysed through the research and subsequently the interpretation of ascertained results is mentioned.
