Predicting Psychotherapy Dropouts: A Multilevel Approach

The role of therapeutic processes in predicting premature termination of psychotherapy has been a particular focus of recent research. The purpose of this study was to contrast outpatients who completed therapy and those who dropped out with respect to their self-reported in-session experiences of self-esteem, mastery, clarification and the therapeutic alliance. The 296 patients with mixed disorders were treated with an integrative form of cognitive–behavioural therapy without pre-determined time limit (M = 20.2 sessions). Multilevel analyses indicated that patients who did not completetreatment reported, on average, lower levels of self-esteem, mastery and clarification and lower ratings of their therapeutic alliance in treatment in contrast to patients who completed therapy. Patient-reported change in self-esteem experiences over the course of treatment turned out to be the strongest predictor of dropout from psychotherapy or successful completion. When dropout occurred before the average treatment length was reached, patients reported fewer clarifying experiences as early as the first session and their ratings of the therapeutic alliance were characterized by an absence of positive development. Both of these aspects seem to be involved in patients' decisions to leave treatment early. The findings underscore the importance of the therapeutic process in understanding the mechanisms behind treatment dropout. Copyright © 2014 John Wiley & Sons, Ltd.

Accumulation, velocities, fluxes and mass balance of glacial tributaries to the Lambert Glacier-Amery Ice Shelf system, Antarctica

By incorporating recently available remote sensing data, we investigated the mass balance for all individual tributary glacial basins of the Lambert Glacier-Amery Ice Shelf system, East Antarctica. On the basis of the ice flow information derived from SAR interferometry and ICESat laser altimetry, we have determined the spatial configuration of eight tributary drainage basins of the Lambert-Amery glacial system. By combining the coherence information from SAR interferometry and the texture information from SAR and MODIS images, we have interpreted and refined the grounding line position. We calculated ice volume flux of each tributary glacial basin based on the ice velocity field derived from Radarsat three-pass interferometry together with ice thickness data interpolated from Australian and Russian airborne radio echo sounding (RES) surveys and inferred from ICESat laser altimetry data. Our analysis reveals that three tributary basins have a significant net positive imbalance, while five other subbasins are slightly positive or close to zero balance. Overall, in contrast to previous studies, we find that the grounded ice in Lambert Glacier-Amery Ice Shelf system has a positive mass imbalance of 22.9 ± 4.4 Gt/a. The net basal melting for the entire Amery Ice Shelf is estimated to be 27.0 ± 7.0 Gt/a. The melting rate decreases rapidly from the grounding zone to the ice shelf front. Significant basal refreezing is detected in the downstream section of the ice shelf. The mass balance estimates for both the grounded ice sheet and the ice shelf mass differ substantially from other recent estimates.

En esta Tesis se plantea una nueva forma de entender la evacuación apoyándonos en tecnologías existentes y accesibles que nos permitirán ver este proceso como un ente dinámico. Se trata de una metodología que implica no solo el uso de herramientas de análisis que permitan la definición de planes de evacuación en tiempo real, sino que también se apunta hacia la creación de una infraestructura física que permita alimentar con información actualizada al sistema de forma que, según la situación y la evolución de la emergencia, sea posible realizar planes alternativos que se adapten a las nuevas circunstancias. En base a esto, el sistema asimilará toda esa información y aportará soluciones que faciliten la toma de decisiones durante toda la evolución del incidente. Las aportaciones originales de esta Tesis son múltiples y muy variadas, pudiéndolas resumir en los siguientes puntos: 1. Estudio completo del estado del arte: a. Detección y análisis de diferentes proyectos a nivel internacional que de forma parcial tratan algunos aspectos desarrollados en la Tesis. b.

Esta Tesis es la base para el proyecto e-Flow (nombre de una de las aplicaciones que desarrolladas en esta obra), un proyecto en el que el autor de esta Tesis ha trabajado como Project Manager. En el proyecto participa un consorcio de empresas y la UPM, y tiene como objetivo trasladar a la realidad gran parte de los planteamientos e ideas presentadas en esta Tesis. Este proyecto incluye el desarrollo de la infraestructura física y de servicios que permitirán, entre otras cosas, implementar en infraestructuras complejas una plataforma que posibilita la evacuación dinámica y un control ubicuo de los sistemas de monitorización y actuación implementados. En estos momentos se está finalizando el proyecto, cuyo objetivo final es la implementación de un piloto en un Hospital. También destacamos los siguientes avances a nivel de difusión científico-tecnológico: • Ponencia en el “52 congreso de la Ingeniería Naval en España” presentando un artículo “e-Flow- Sistema integral inteligente de soporte a la evacuación”. En este artículo se trata tanto el proyecto e-Flow del que soy Project Manager, como esta Tesis Doctoral, al ser temas estrechamente vinculados. En 2014 se publicó en dos números de la Revista Ingeniería Naval el artículo presentado a estas jornadas. • Co-autor en el artículo “E-Flow: A communication system for user notification in dynamic evacuation scenarios” presentado en el 7th International Conference on Ubicuous Computing & Ambient Intelligence (UCAMI) celebrado en Costa Rica. Por último, una de las aportaciones más interesantes, es la definición de un gran número de líneas de investigación futuras en base a todos los avances realizados en esta Tesis. ABSTRACT With this Thesis a new approach for understanding evacuation process is considered, taking advantage of the existing and open technologies that will allow this process to be interpreted as a dynamic entity. The methodology involves not only tools that allows on.-time evacuation plans, but also creates a physical insfrastructure that makes possible to feed the system with information on real time so, considering in each moment the real situation as well as the specific emergency development it will be feasible to generate alternative plans that responds to the current emergency situation. In this respect, the system will store all this information and will feedback with solutions that will help the decision making along the evacuation process. The innovative and singular contributions of this Thesis are numerous and rich, summarised as follows: 1.- Complete state-of-art study: a. Detection and analysis of different projects on an international level that, although partially, deal with some aspects developed in this Thesis. b. Thorough study at a international level of the developed software - total or partially done - for the simulation of the human behaviour and evacuation processes analysis. A database has been generated that classifies in detail these applications allowing to perform a full analysis and leading to future evolution of its contents. Within the Thesis work, almost a hundred of developments have been analysed but the purpose is to keep up updating this database due to the broad applications and possibilities that it involves. 2. Development of an important chapter that studies the possibility of using virtual scenarios as mid-term alternative for the use of simulations. This section is divided in two blocks: a. Trials in virtual and real scenarios b. Trials in virutal scenarios (trials performed with several ones). 3. E-Flow net design development: Set of tools developed under Rhinoceros for the evacuation net design based on the elements defined in the Thesis: Nodes, Paths, Relations, Areas 4. E-Flow simulator development: Set of tools that uses Rhinoceros as a 3D simulator of human behaviour. This simulator, of my own design, includes a new and original algorithm of human behaviour that involves aspects that are not found in other simulators. This tool allows to perform groups programmed simulations which behaviour is based on their enviroment analysis and presence of dynamic references. It includes other important innovations as for example: tools for signals analysis, dynamic signal elements, easy obstacle adding etc... More over, a tool that allows the own scenario movement implementation has been created by simulating the own oscillation movement, with the purpose of playing the vessel movement's influences in the individuals' displacements. 5. In an advanced stage of the development, the possibility of generating a video recording of all the simulation was also integrated, then from that moment all tests have been filed (and keep on doing so) in a database that collects all simulation characteristics, failures detected, etc. These stored tests amounts to a total of 81 GB at the moment of finishing the Thesis work. Generation and analysis of paths regarding the evacuation net created with E-Flow design and the simulations performed with E-Flow net Simulator. a. Analysis for the optimisation of the network configuration based in the existing nodes per area. b. Definition of the processes previous to the calculation of the feasible paths c. Paths calculation: i. Analysis of the different algorithms on existance nowadays for the routes optimisation. ii. Development of a new family of algorithms that I have called “Minimum Decision Algorithm (MDA)”, being composed of: 1. MDA basic 2. MDA minimum 3. MDA of not spacial interference 4. MDA of expansion (es de extenderse) o enlargement ( es de crecimiento) 5. MDA of organised expansion for a single origin (of organised enlargement for a single origin) 6. MDA of organised expansion (of organised enlargement) iii. All these algorithms have been implemented in the E-Flow application created in the Thesis dfor the routes analysis and it is the core of the Captain's support system. d. Determination of the alternatives for the evacuation plan. After defining all possible paths, different processes of analysis existing for weighing-based criteria are described, thus to end defining the own development method proposed in this Thesis and that aims to respond in an agreggation of possible routes basis obtained by means of the MDA algorithms what is the routes' combination more suitable for the Plan or Plans in every situation. The methodology created fot the selection of the combinations of routes that determine a complete Plan is baesd in four basic criteria that after applying, offer the best alternatives. In this stage a complex analysis of the progress along time is also included, that adds original and innovative defintions and formulations. e. Originated from the methodology created in this Thesis for the perfoming of the analysy of the progress along time, a new mathematic theorem has been defined, that has been called as "Family of quadrilateral of constant area". 7. Specification of the physiscal infrastructure of the Captain's help system: essential part is this physical infrastructure that will support it. This system will be made of sensors, actuators, apps for mobile devices etc... Within this chapter the different elements and technologies that make up this infrastructure will be studied. 8. Specification for the services infrastructure. 9. Start up of the Blog. " Virtual Environments (http://epcinnova-virtualenvironments.blogspot.com.es/)" in which all tests performed have been published in terms of analysis of the virtual enviroments as alternative to the simulators as well as to the laboratory experiments or simulations, including in most of the cases the possibility that the visitor can perform the simulation within the virtual enviroment. This blog also includes other sections that have been worked along and within this Thesis: - Collection of different virtual scenarios existent. - Schema that gathers information concerning accidents for maritime and terrestrial areas (under development) - Schema proposed for the collecting of information obtained from a simulation. 10. This Thesis is the basis of the E-Flow project (name of one of the applications developed in this work), a project in which the Thesis' author has worked in as Project Manager. In the project takes part a consortium of firms as well as the UPM and the aim is to bring to real life most part of the approaches and ideas contained in this Thesis. This project includes the development of the physical infrastructure as well as the services that will allow, among others, implement in complex infrastrucutres a platform that will make possible a dynamic evacuation and a continuous control of the monitoring and acting systems implemented. At the moment the project is getting to an end which goal is the implementation of a pilot project in a Hospital. We also would like to highlight the following advances concerning the scientific-technology divulgation: • Talk in the " 52th Congress of the Naval Engineering in Spain" with the article "E-Flow . Intelligent system integrated for supporting evacuation". This paper is about project E-Flow which I am Project Manager of, as well as this Thesis for the Doctorate, being both closely related. Two papers published In 2014 in the Naval Engineering Magazine. • Co-author in the article “E-Flow: A communication system for user notification in dynamic evacuation scenarios” [17] introduced in the 7th International Conference on Ubicuous Computing & Ambient Intelligence (UCAMI) held in Costa Rica. Last, but not least, one of the more interesting contributions is the defintion of several lines of research in the future, based on the advances made in this Thesis.

The US-China Joint Announcement on Climate Change: Can the G2 make a difference? CEPS Commentary, 26 November 2014

This Commentary finds that the US-China joint declaration on climate change, issued following the Asia-Pacific Economic Cooperation (APEC) Summit in Beijing on November 12th, is undoubtedly an important announcement by the two global economic giants responsible for emitting over 30% of the world’s GHG emissions. As such, it needs to be seen as important and relevant – a very positive development towards a new global climate change agreement in Paris. It is a challenge to those that have announced their pledges and are seen as capable of doing more, as well as to those that have not yet announced their intentions. It shows the importance and success of the UN climate change conference in Warsaw last year, when the decision was made that all Parties should announce their commitments by the first quarter of 2015. It also represents a total breakdown of the Kyoto Protocol-style separation in climate change negotiations between countries into Annex 1 and non-Annex 1, with China signalling that it is taking on the leadership role that comes with being a great economic power. In broader terms, it shows that there is scope for cooperation between the two main economic actors, even in the face of competition in other spheres. It is also a challenge to the EU, which was a leader and needs to show that there is a benefit in maintaining its leadership. Finally, agreements are deemed historic only by history. This one is important, and a potential game-changer, on the face of it. But it needs to live up to its promise. There is sufficient uncertainty for us to withhold final judgement and see if its promise materialises through implementation. But, as sober a judgement as we must make on such important matters, this announcement certainly gives us great hope that it is possible to do what needs to be done, and we must wholeheartedly welcome and applaud it.

The new Inter-Parliamentary Conference on the CFSP/CSDP. Jean Monnet/Robert Schuman Paper Series Vol. 14 No. 12, July 2014

The objectives of the 2009 Lisbon Treaty (LT) include ways to improve the democratic and international images of the European Union (EU). The focus of the literature has so far focused on the overall treaty impact and on the EU´s international role. This paper considers instead its impact on the question of the democratic accountability of the EU´s Common Foreign and Security Policy (CFSP), including its Common Security and Defence Policy dimension (CSDP). This paper consists of three parts: (1) The first part describes the changes the LT has made for the European Parliament (EP) in terms of its external relations. (2) The second part presents the many deficits that the EU suffers from in its foreign, security and defence policies. (3) The third part offers a preliminary analysis of the recently created Inter-Parliamentary Conference (IPC) on CFSP/CSDP, which in addition to MEPs (EP members) includes parliamentarians from the national EU parliaments. The paper concludes that although the IPC is a positive development in trying to bridge those existing democratic gaps, it remains only a step in the right direction due to the existence of many such deficits in the foreign, security and defence policies of the EU and of its member states.

Common E protein determinants for attenuation of glycosaminoglycan-binding variants of Japanese encephalitis and West Nile viruses

Natural isolates and laboratory strains of West Nile virus (WNV) and Japanese encephalitis virus (JEV) were attenuated for neuroinvasiveness in mouse models for flavivirus encephalitis by serial passage in human adenocarcinoma (SW13) cells. The passage variants displayed a small-plaque phenotype, augmented affinity for heparin-Sepharose, and a marked increase in specific infectivity for SW13 cells relative to the respective parental viruses, while the specific infectivity for Vero cells was not altered. Therefore, host cell adaptation of passage variants was most likely a consequence of altered receptor usage for virus attachment-entry with the involvement of cell surface glycosaminoglycans (GAG) in this process. In vivo blood clearance kinetics of the passage variants was markedly faster and viremia was reduced relative to the parental viruses, suggesting that affinity for GAG (ubiquitously present on cell surfaces and extracellular matrices) is a key determinant for the neuroinvasiveness of encephalitic flaviviruses. A difference in pathogenesis between WNV and JEV, which was reflected in more efficient growth in the spleen and liver of the WNV parent and passage variants, accounted for a less pronounced loss of neuroinvasiveness of GAG binding variants of WNV than JEV. Single gain-of-net-positive-charge amino acid changes at E protein residue 49, 138, 306, or 389/390, putatively positioned in two clusters on the virion surface, define molecular determinants for GAG binding and concomitant virulence attenuation that are shared by the JEV serotype flaviviruses.

Does the motivation for foreign direct investment affect productivity spillovers to the domestic sector?

There is increasing empirical and theoretical evidence that foreign direct investment (FDI) may be motivated not by the desire to exploit some competitive advantage possessed by multinationals, but to access the technology of host economy firms. Using a panel of FDI flows across OECD countries and manufacturing sectors between 1984 and 1995, we test whether these contrasting motivations influence the effects that FDI has on domestic total factor productivity. The distinction between technology-exploiting FDI (TEFDI) and technology-sourcing FDI (TSFDI) is made using R&D intensity differentials between host and source sectors. The hypothesis that the motivation for FDI has an effect on total factor productivity spillovers is supported: TEFDI has a net positive effect, while TSFDI has a net negative effect. These net effects are explained in terms of the offsetting influences of productivity spillovers and market stealing effects induced by incoming multinationals.

An investigation of multiple pathways of developmental intervention change

Convergence among treatment, prevention, and developmental intervention approaches has led to the recognition of the need for evaluation models and research designs that employ a full range of evaluation information to provide an empirical basis for enhancing the efficiency, efficacy, and effectiveness of prevention and positive development interventions. This study reports an investigation of a positive youth development program using an Outcome Mediation Cascade (OMC) evaluation model, an integrated model for evaluating the empirical intersection between intervention and developmental processes. The Changing Lives Program (CLP) is a community supported positive youth development intervention implemented in a practice setting as a selective/indicated program for multi-ethnic, multi-problem at risk youth in urban alternative high schools. This study used a Relational Data Analysis integration of quantitative and qualitative data analysis strategies, including the use of both fixed and free response measures and a structural equation modeling approach, to construct and evaluate the hypothesized OMC model. Findings indicated that the hypothesized model fit the data (χ2 (7) = 6.991, p = .43; RMSEA = .00; CFI = 1.00; WRMR = .459). Findings also provided preliminary evidence consistent with the hypothesis that in addition to having effects on targeted positive outcomes, PYD interventions are likely to have progressive cascading effects on untargeted problem outcomes that operate through effects on positive outcomes. Furthermore, the general pattern of findings suggested the need to use methods capable of capturing both quantitative and qualitative change in order to increase the likelihood of identifying more complete theory informed empirically supported models of developmental intervention change processes.

Small farmer market knowledge and specialty coffee commodity chains in Western Highlands Guatemala

For producers motivated by their new status as self-employed, landowning, capitalist coffee growers, specialty coffee presents an opportunity to proactively change the way they participate in the international market. Now responsible for determining their own path, many producers have jumped at the chance to enhance the value of their product and participate in the new "fair trade" market. But recent trends in the international coffee price have led many producers to wonder why their efforts to produce a certified Fair Trade and organic product are not generating the price advantage they had anticipated. My study incorporates data collected in eighteen months of fieldwork, including more than 45 interviews with coffee producers and fair trade roasters, 90 surveys of coffee growers, and ongoing participant observation to understand how fair trade certification, as both a market system and development program, meets the expectations of the coffee growers. By comparing three coffee cooperatives that have engaged the Fair Trade system to disparate ends, the results of this investigation are three case studies that demonstrate how global processes of certification, commodity trade, market interaction, and development aid effect social and cultural change within communities. This study frames several lessons learned in terms of (1) socioeconomic impacts of fair trade, (2) characteristics associated with positive development encounters, and (3) potential for commodity producers to capture value further along their global value chain. Commodity chain comparisons indicate the Fair Trade certified cooperative receives the highest per-pound price, though these findings are complicated by costs associate with certification and producers' perceptions of an "unjust" system. Fair trade-supported projects are demonstrated as more "successful" in the eyes of recipients, though their attention to detail can just as easily result in "failure". Finally, survey results reveal just how limited is the market knowledge of producers in each cooperative, though fair trade does, in fact, provide a rare opportunity for producers to learn about consumer demand for coffee quality. Though bittersweet, the fair trade experiences described here present a learning opportunity for a wide range of audiences, from the certified to the certifiers to the concerned public and conscientious consumer.

Kommunikative Partizipation und Integrationserleben hörgeschädigter Schülerinnen und Schüler an einer Schwerpunktschule

Schwerpunktschulen, die von einer größeren Anzahl von hörgeschädigten Schülerinnen und Schülern besucht werden, stellen in Bezug auf die psychosoziale Entwicklung hörgeschädigter Kinder eine in den letzten Jahren vermehrt in die Diskussion gebrachte alternative Bildungsoption zur Einzelinklusion dar. In der vorliegenden Fragebogenstudie wurden 35 Schülerinnen und Schüler einer Schwerpunktschule in Bezug auf ihre erlebte Partizipation im Unterricht, ihr Integrationserleben sowie auf Verhaltensauffälligkeiten und Lebensqualität untersucht. Die Ergebnisse zeigen insgesamt eine positive Entwicklung in allen überprüften Bereichen mit behinderungsspezifischen Besonderheiten, die in der pädagogischen Begleitung hörgeschädigter Kinder beachtet werden müssen. Vergleiche zu Daten aus anderen Studien mit einzelintegrierten hörgeschädigten Kindern ergeben keine Unterschiede. Pädagogische Konsequenzen sowie Herausforderungen für weiterführende Studien werden diskutiert. (DIPF/Orig.)

RESPONSE OF LOCALLY ADAPTED PEARL MILLET POPULATIONS TO S1 PROGENY RECURRENT SELECTION FOR GRAIN YIELD AND RESISTANCE TO RUST

In the semi-arid zones of Uganda, pearl millet ( Pennisetum glaucum (L.) R. Br.) is mainly grown for food and income; but rust (Puccinia substriata var indica (L.) R. Br.) is the main foliar constraint lowering yield. The objective of the study was to genetically improve grain yield and rust resistance of two locally adapted populations (Lam and Omoda), through two cycles of modified phenotypic S1 progeny recurrent selection. Treatments included three cycles of two locally adapted pearl millet populations, evaluated at three locations. Significant net genetic gain for grain yield (72 and 36%) were achieved in Lam and Omoda populations, respectively. This led to grain yield of 1,047 from 611 kg ha-1 in Lam population and 943 from 693 kg ha-1 in Omoda population. Significant improvement in rust resistance was achieved in the two populations, with a net genetic gain of -55 and -71% in Lam and Omoda populations, respectively. Rust severity reduced from 30 to 14% in Lam population and from 57 to 17% in Omoda population. Net positive genetic gains of 68 and 8% were also achieved for 1000-grain weight in Lam and Omoda, respectively. Traits with a net negative genetic gain in both populations were days to 50% flowering, days to 50% anthesis, days to 50% physiological maturity, flower-anthesis interval, plant height and leaf area.

Orthopaedic anaesthesia for upper extremity procedures in a Nigerian hospital

Background General anaesthesia and regional anaesthesia have been used successfully for upper extremity orthopaedic procedures. Despite the advantages of regional anaesthesia, there is low utilisation in Nigeria. In this study, we assessed the types of anaesthesia employed for upper extremity surgeries in our centre. Methods After obtaining approval from the institutional ethics committee, all the patients who had upper extremity surgeries from 1 January 2011 to 31 December 2012 were included in this review. Both prospective and retrospective data were gathered. The choice of anaesthesia was at the discretion of the attending anaesthetist. Results A total of 226 patients with a male-to-female ratio of 1.6:1 and median age of 35.0 (range 2 – 89) years, had orthopaedic upper extremity procedures during the study period. Sixty-three cases (27.9%) had general anaesthesia, 5 (2.2%) combined regional and general anaesthesia while 158 (69.9%) had regional blocks. The regional blocks comprised 145 (89%) different approaches to the brachial plexus and 18 (11%) local anaesthetic infiltrations. The arm was the site mostly operated upon; while supraclavicular and axillary brachial plexus blocks were performed in equal amounts. In 14 (6.2%) patients, brachial plexus blocks were performed with spinal anaesthesia because of concomitant iliac crest bone grafts. While the duration of surgery did not differ significantly, regional anaesthesia provided a significantly longer duration of anaesthesia than general anaesthesia (251 ± 70.8 min versus 141.3 ± 65.5 min; p = 0.0000001). Conclusion There is a high use of regional anaesthesia for upper extremity orthopaedic surgeries in our centre, which is a positive development in a resource limited setting.

Teamwork and leadership : competitive youth soccer as a context for positive youth development

The purpose of this study was to examine processes and interactions that characterized positive developmental experiences in sport. A highly competitive and reputable U-17 girls' soccer team was chosen for the study through purposeful sampling, providing an information rich case from which data could be derived (Patton, 2002). Seventeen players and three coaches participated in this study. Based on an ethnographic methodology data were collected via observations and both informal and formal semi-structured interviews. Tlie data were coded according to the three procedures outlined by Seidel and Kelle (1995): a) noticing relevant phenomena, b) collecting examples of those phenomena, and c) analyzing those phenomena in order to find commonalities, differences, patterns and structures. Significant events and underlying themes were recounted chronologically through a collection of vignettes, aimed to provide a contextual lens for the reader. Results revolved around two prominent themes: Teamwork and leadership. These were closely related concepts that required players to demonstrate a wide range of developmental skills for the team to move collectively towards their end goal. Furthermore, teamwork and leadership experiences took both desirable and undesirable forms. For example, at the beginning of the season competition existed amongst the players at the expense of teamwork and leadership. As the season progressed the pursuit of a shared goal allowed the players to view each other as collaborators and teamwork and leadership skills became increasingly evident. At times, however, success on the field was prioritized above maintaining relationships off the field, requiring the coaches to intervene and re-establish equilibrium.

The Influence of Motivational Behaviours and Goal Profiles on Positive Youth Development

Positive Youth Development (PYD) research has started to shift focus onto how different internal factors such as temperament, dispositions, and/or personality characteristics could influence levels of PYD for youth participating is organized sport. The purpose of this study is to examine how different goal profiles, specifically categorized by diverse levels of task and ego orientation, can influence levels of PYD in an organized youth sport setting. One hundred youth sport participants (mean age = 16.8) completed the short form Youth Experiences Survey for Sport (short form YES-S; Sullivan et al., 2013) to measure PYD, as well as the Task and Ego Orientation in Sport Questionnaire (TEOSQ; Duba 1989) to assess each athlete’s goal profile. A TwoStep Cluster Analysis was used to classify each individual’s personal goal profile into 3 statistically different cluster groupings. Results indicated significant interaction between the PYD outcome factor of Initiative vs. Clusters [F(2,95)= 10.86, p < 0.001, p2= 0.19] as well as Goal Setting vs. Clusters [F(2,95)= 3.95, p < 0.05, p2= 0.08]. Post-hoc analyses provided results that suggest that those athletes who are more task oriented have fostered more positive outcomes from sport, therefore having more goal setting skills and initiative.
