Self determination theory

Nicholas P van der Munnik, Md Symon Jahan Sajib, Melissa A Moss, Tao Wei, Mark J Uline
Amyloid-β (Aβ) protein aggregates through a complex pathway to progress from monomers to soluble oligomers and ultimately insoluble fibrils. Due to the dynamic nature of aggregation, it has proven exceedingly difficult to determine the precise interactions that lead to the formation of transient oligomers. Here, a statistical thermodynamic model has been developed to elucidate these interactions. Aβ1-42 was simulated using fully-atomistic replica exchange molecular dynamics. We use an ensemble of approximately 5×105 configurations taken from simulation as input in a self-consistent field theory that explicitly accounts for the size, shape and charge distribution of both the amino acids comprising Aβ and all molecular species present in solution...

OBJECTIVE: The purpose of this study was to construct a computerized adaptive test (CAT) for measuring self-care performance (the CAT-SC) in children with developmental disabilities (DD) aged from 6 months to 12 years in a content-inclusive, precise, and efficient fashion. METHODS: The study was divided into 3 phases: (1) item bank development, (2) item testing, and (3) a simulation study to determine the stopping rules for the administration of the CAT-SC. A total of 215 caregivers of children with DD were interviewed with the 73-item CAT-SC item bank...

Psychiatric illness can pose serious risks to pregnant and postpartum women and their infants. There is a need for screening tools that can identify women at risk for postpartum psychosis, the most dangerous perinatal psychiatric illness. This study used exploratory factor analysis (EFA) and Rasch item response theory (IRT) models to evaluate the psychometric properties and construct validity of the Spanish language version of the 16-item Prodromal Questionnaire (PQ-16) as a screening tool for psychosis in a population of pregnant Peruvian women...

AIMS: To investigate associations between health literacy (HL) and diet and physical activity, and motivation and diet and physical activity in Danish people with type 2 diabetes. METHODS: We used a cross-sectional design including 194 individuals with type 2 diabetes participating in peer-led support groups provided by the Danish Diabetes Association between January-December 2015. The participants completed a questionnaire at the first meeting including; The Summary of Diabetes Self-Care Activities (SDSCA) measure, The Treatment Self-Regulation Questionnaire (TSRQ) (Self-Determination Theory) measuring type of motivation, and two HL scales: The HLS-EU-Q16, and the Diabetes Health Literacy scale (Ishikawa, H)...

Background: The transition of young adults with type 1 diabetes (T1D) from pediatric to adult care is challenging and frequently accompanied by worsening of diabetes-related health. To date, there are no reports which prospectively assess the effects of theory-based psycho-behavioral interventions during the transition period neither on glycemic control nor on psychosocial factors that contribute to poor glycemic control. Therefore, the overall aim of this study was to develop and pilot test an integrative group intervention based on the underlying principles of self-determination theory (SDT), in young adults with T1D...

In this paper, we systematically derive a fourth-order continuum theory capable of reproducing mesoscale turbulence in a three-dimensional suspension of microswimmers. We start from overdamped Langevin equations for a generic microscopic model (pushers or pullers), which include hydrodynamic interactions on both small length scales (polar alignment of neighboring swimmers) and large length scales, where the solvent flow interacts with the order parameter field. The flow field is determined via the Stokes equation supplemented by an ansatz for the stress tensor...

Almost all functionals that are currently used in density matrix functional theory have been created by some a priori ansatz that generates approximations to the second-order reduced density matrix (2RDM). In this paper, a more consistent approach is used: we analyze the 2RDMs (in the natural orbital basis) of rather accurate multi-reference configuration interaction expansions for several small molecules (CH4 , NH3 , H2 O, FH, and N2 ) and use the knowledge gained to generate new functionals. The analysis shows that a geminal-like structure is present in the 2RDMs, even though no geminal theory has been applied from the onset...

INTRODUCTION: The benefits of physical activity for children's health, both mental and physical, and its positive effects on academic achievement are well established. Research also emphasises that schools could provide a natural setting for regular physical activity. There is, however, a limited amount of knowledge about teachers' views when it comes to integrating physical activity as part of teaching. The aim of this study is to understand teachers' motivation for integrating physical activity as part of teaching and to assess their need for guidance and support...

Self-complementary circular codes are involved in pairing genetic processes. A maximal [Formula: see text] self-complementary circular code X of trinucleotides was identified in genes of bacteria, archaea, eukaryotes, plasmids and viruses (Michel in Life 7(20):1-16 2017, J Theor Biol 380:156-177, 2015; Arquès and Michel in J Theor Biol 182:45-58 1996). In this paper, self-complementary circular codes are investigated using the graph theory approach recently formulated in Fimmel et al. (Philos Trans R Soc A 374:20150058, 2016)...

Background and Objectives: As proposed by the self-determination theory, satisfying nursing home residents' needs for autonomy, relatedness, and competence may improve their well-being. This is the first study to test the longitudinal relations of the satisfaction of these three basic psychological needs to the subjective well-being of nursing home residents and to determine whether a balance among the satisfaction of the three needs is important for well-being. Research Design and Methods: Participants in this longitudinal survey study included 128 physically frail residents (mean age 85 years) at four Dutch nursing homes...

Engaging in physical activity (PA) on a regular and adequate basis generates considerable benefits for health. In developed countries, the time spent doing PA is decreasing, whilst sedentary time (ST) is increasing. A multicomponent school-based intervention programme, called 'Sigue la Huella' (Follow the Footprint), was developed to reduce sedentary lifestyles and increase PA levels. This programme has proven to be effective in increasing the daily levels of moderate to vigorous PA, in decreasing ST and in improving motivational outcomes in secondary education students, in the city of Huesca (Spain)...

One of the enduring missions of personality science is to unravel what it takes to become a fully functioning person. In the present article, the authors address this matter from the perspectives of self-determination theory (SDT) and personality systems interactions (PSI) theory. SDT a) is rooted in humanistic psychology; b) has emphasized a first-person perspective on motivation and personality; c) posits that the person, supported by the social environment, naturally moves towards growth through the satisfaction of basic psychological needs for autonomy, competence, and relatedness...

OBJECTIVE: Work on longevity has found protective social, cognitive and emotional factors, but to date we have little understanding of the impact of motivational dynamics. Autonomy orientation, or stable patterns of self-regulation, is theorized to be a protective factor for long-term mental and physical health (Ryan & Deci, 2017), and is therefore a prime candidate for examining how stable psychosocial factors are linked to longevity, or life expectancy. METHOD: Essays written in the 1930s by participants in the Nun Study were coded for indicators of an autonomy orientation...

Self-determination theory (SDT) has advanced the most comprehensive model of motives for human flourishing in the field of personality psychology and beyond. In this article, we evaluate SDT relative to the process of meaning-making, particularly from a narrative perspective, showing what SDT can and cannot explain about the construction of self-identity and its relation to human flourishing. On the one hand, SDT explains how subjective assessments of need fulfillment drive the process of self-determined living...

OBJECTIVES: Self-efficacy - an individual's judgement of their ability to successfully perform a behaviour - is commonly used to explain and predict behaviour. It is measured through self-report questionnaires. These scales require good content validity, that is must measure the full scope and content of the construct without contamination from similar constructs. This study uses a systematic, transparent quantitative method (discriminant content validation, DCV) to assess the content validity of a variety of self-efficacy items and qualitatively explores participant interpretations of these items...

Adverse prenatal environmental influences to the developing fetus are associated with mental and cardiovascular disease in later life. Universal developmental characteristics such as self-organization, pattern formation, and adaptation in the growing information processing system have not yet been sufficiently analyzed with respect to description of normal fetal development and identification of developmental disturbances. Fetal heart rate patterns are the only non-invasive order parameter of the developing autonomic brain available with respect to the developing complex organ system...

BACKGROUND AND AIMS: Based on the principles of scaffolding for motivation and on the assumptions of self-determination theory, two studies aimed to assess the role played by perceived parental autonomy-supportive scaffolding on child homework autonomous motivation, self-efficacy, affect, and engagement. SAMPLES AND RESULTS: The results of Study 1, which involved 122 parents and their children, showed that the higher the parental autonomous motivation, the more their children perceived them as autonomy-supportive while scaffolding for motivation, and hence developed autonomous motivation, self-efficacy, and engagement in homework...

Binge eating disorder, food addiction, and dysregulated overeating are common among people with severe obesity and prevalent among bariatric surgery populations. These problematic eating habits share commonalities with other addictions. Effective, holistic self-management is needed to promote long-term weight loss and psychosocial adjustment among patients who are severely obese who undergo surgery, especially those with clinically remarkable levels of binge eating, food addiction, or dysregulated overeating...

BACKGROUND: Student satisfaction is a quality measure of increasing importance in undergraduate programs, including nursing programs. To date theories of student satisfaction have focused primarily on students' perceptions of the educational environment rather than their perceptions of learning. Understanding how students determine satisfaction with learning is necessary to facilitate student learning across a range of educational contexts and meet the expectations of diverse stakeholders...
