Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior…

2020

Objectives The present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context. Methods The study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; Mage = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs controlling…

Predictors of In‐School and Out‐of‐School Sport Injury Prevention : A Test of The Trans‐Contextual Model

2021

The current study aimed to predict secondary school students' motivation toward sport injury prevention in 'in-school' and 'out-of-school' contexts, and their sport injury prevention behaviour at 3-month follow-up using the trans-contextual model (TCM). Hong Kong secondary school students (N = 1,566; mean age = 13.34 years, range = 11 to 19; female = 49.42%) were recruited. Participants were asked to complete a survey comprising previously-validated scales measuring TCM constructs at baseline, and a measure of sport injury prevention behaviour at follow-up three months later. Structural equation modeling (SEM) was used to examine the hypothesised paths among TCM constructs. A SEM specifying…

Psychological processes of ACL-patients' post-surgery rehabilitation : A prospective test of an integrated theoretical model

2020

Objectives: The aim of this prospective study was to examine the utility of an integrated model comprising constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) in predicting adherence to a post-surgery rehabilitation program in patients receiving anterior cruciate ligament (ACL) reconstruction. Constructs of the integrated model measured at baseline were expected to predict patients' rehabilitation adherence two months later. Method: Patients (N = 121, M age = 27.62, range = 18–53; 36.66% female) scheduled to have ACL reconstruction surgery within two months were recruited from a Hong Kong public hospital. At baseline and two-month follow-up, patients com…

MR Imaging of Uterus Didelphys Transverse Vaginal Septum Causing Hematometrocolpos and Renal Agenesis

2002

The association of uterus didelphys and unilateral blind vagina with ipsilateral renal agenesis is an infrequent urogenital malformation distinguished by a lesion of the mesonephric duct. In most patients, symptoms are present at the beginning of the menstrual cycle because a transverse vaginal septum on one side obstructs the flow of menses, which consequently collect. Magnetic resonance imaging allows a precise delineation of this congenital abnormality, clearly demonstrating the transverse vaginal septum with hematometrocolpos and uterus didelphys. Extending the magnetic resonance study to the abdomen and employing coronal sections with a wide field of view is important to search for ass…

Fertility and immunosuppression in allogeneic uterus transplantation

2015

A pesar de los avances en medicina reproductiva alcanzados durante las últimas tres décadas, la esterilidad absoluta de origen uterino (AUFI, por sus siglas en inglés), a día de hoy, carece de tratamiento. Ésta, puede ser causada tanto por la ausencia del útero (congénita o adquirida) o la no funcionalidad del mismo [1, 2]. Cálculos en el Reino Unido han demostrado que hay alrededor de 12000 a 15000 mujeres en edad reproductiva con infertilidad uterina en dicho país [3]. No hay cálculos correspondientes a España, pero extrapolando datos sobre prevalencia de causas de AUFI, se estima que puede haber alrededor de 2000-3000 mujeres en edad fértil que no tienen ninguna oportunidad de ser biológ…

Referee efficacy in the context of Norwegian soccer referees – A meaningful construct?

2018

Abstract Objectives The purpose of this study was two-fold. Firstly, to examine the measurement/factorial validity and invariance of the Referee Self-Efficacy Scale (REFS) among Norwegian soccer referees. Secondly, extending scale validation, we also tested a structural model in which a second-order version of the REFS was modelled to mediate a set of theoretically informed antecedents and outcomes. Design Cross-sectional. Method One hundred and eleven Norwegian elite referees and 81 non-elite referees completed an electronic questionnaire measuring expected antecedents and outcomes of perceived self-efficacy in the role as referees. Results Analyses provided support for the first – and sec…

Adaption and validation of the German version of the basic psychological needs in physical education scale

2013

It is important to understand students’ motivation regarding physical activity to investigate the global issue physical inactivity. Based on the self-determination theory (SDT: Ryan & Deci, 2002), which is one of the most important frameworks in explaining motivation, students need to be emotionally satisfied in order to put effort towards a certain goal. The Basic Psychological Needs Theory is one sub-theory of the self-determination theory, which explains that constructs of autonomy, competence, and relatedness need to be satisfied in all humans in order to increase well-being. It is important to understand students’ motivation regarding physical activity to investigate the global issue o…

Revisiting a Previously Validated Temperament Test in Shelter Dogs, Including an Examination of the Use of Fake Model Dogs to Assess Conspecific Soci…

2019

This study assessed the feasibility and reproducibility of a previously validated temperament test (TT) for shelter dogs. The test was developed to measure dog behaviour in the kennel, and traits of sociability towards people and other dogs, docility to leash, playfulness, cognitive skills, and reactivity. We introduced the use of differently sized fake dogs to check their appropriateness in correctly assessing sociability to dogs to broaden its applicability (as the original study used real stimulus dogs). We hypothesised that dogs&rsquo

Validation of the swimming competence questionnaire for children

2020

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequenc…
