Calculating the implied correlation matrix for a Path Analysis model
2014
To overcome the limitations of two existing methods for calculating a Path Analysis implied correlation matrix, this paper presents an alternative method for calculating this matrix. This new method is based on a recurrence principle which is easy and quick to implement. This method is also operational regardless of the number of variables. The consequences of this result with the estimation or testing stages will be illustrated on the basis of examples.
Deflation-Corrected Estimators of Reliability
2022
Underestimation of reliability is discussed from the viewpoint of deflation in estimates of reliability caused by artificial systematic technical or mechanical error in the estimates of correlation (MEC). Most traditional estimators of reliability embed product–moment correlation coefficient (PMC) in the form of item–score correlation (Rit) or principal component or factor loading (λi). PMC is known to be severely affected by several sources of deflation such as the difficulty level of the item and discrepancy of the scales of the variables of interest and, hence, the estimates by Rit and λi are always deflated in the settings related to estimating reliability. As a short-cut to deflation-c…
A checklist to assess the quality of survey studies in psychology
2020
Abstract Study quality is emerging as an essential component of evidence syntheses. It allows practitioners and policymakers to make informed decisions based on the quality of the evidence reviewed. Study quality is typically assessed by checklists of pre-determined quality criteria. Few study quality checklists have been systematically evaluated, and none have been developed specifically for survey studies in psychology. The present study addresses this evidence gap by developing the quality of survey studies in psychology (Q-SSP) checklistusing an expert-consensus method. An international panel of experts in psychology research and quality assessment (N = 53) evaluated the inclusion and i…
THE INFLUENCE OF TEACHER-STUDENT COMMUNICATION ON THE IMPORTANCE OF PHYSICAL EDUCATION
2021
During adolescence, there is a significant risk of sports abandonment associated with sedentarism and overweight. For this reason, Physical Education (PE) classes should be an opportunity to bring physical activity and sport closer to schoolchildren developing, and consolidating healthy lifestyle habits. Considering the importance that teaching communication procedures can have in the motivation of students, and given the lack of specific studies that investigate the influence of these processes on the motivation to practice sport in the context of PE, the aim of this study is to determine the effect of the teacher's communicational dimensions (challenging, encouragement and praise, non-ver…
Style partycypacji kulturalnej człowieka dorosłego. Walidacja narzędzia pomiarowego
2018
The article presents a measurement tool validation process diagnosing an adult person’s cultural participation styles. Its objective is to describe the obtained results at individual stages of the validation and determine the connection between cultural participation styles and cultural systems presented by sociologists of culture. Consequently, cultural participation style of an adult person is the subject of the research. The pilot studies as well as the actual research have been conducted in Opolskie province. The research sample amounted to 100 respondents, then 400 respondents, respectively. The theoretical construct of Kazimierz Obuchowski describing the objective and subjective stand…
Who can best report on children's motor competence: Parents, teachers, or the children themselves?
2018
Abstract Objective A positive perception of motor competence (MC) is important for children's health trajectory. It is purported that young children's perception is not well aligned with their actual ability. Alternative sources of perceptions are postulated from children's social context such as their parents or teachers. This study aims to analyse the associations among children's, parents' and Physical Education (PE) teachers' perception of children's MC and the children's actual MC, and whether these sources of information can report on children's actual MC. Design and method A convenience sample of 139 typically developed children (48.2% girls) from six schools participated in this cro…
Addiction-Like Mobile Phone Behavior – Validation and Association With Problem Gambling
2018
Mobile phone use and its potential addiction has become a point of interest within the research community. The aim of the study was to translate and validate the Test of Mobile Dependence (TMD), and to investigate if there are any associations between mobile phone use and problem gambling. This was a cross-sectional study on a Swedish general population. A questionnaire consisting of a translated version of the TMD, three problem gambling questions (NODS-CLiP) together with two questions concerning previous addiction treatment was published online. Exploratory factor analysis based on polychoric correlations was performed on the TMD. Independent samples T-tests, Mann-Whitney test, logistic …
Assessing attention allocation toward threat-related stimuli: a comparison of the emotional Stroop task and the attentional probe task
2003
This study examined the association of two widely used measures of attention allocation toward or away from threat-related stimuli: The emotional Stroop task and the attentional probe task. Fifty-three participants responded to computer versions of both tasks where stimuli were presented both subliminally and supraliminally. Thus, four indexes indicating attention allocation were computed for each participant. A correlation analysis showed that the attentional probe index and the emotional Stroop index were associated within each presentation mode while all other relations were nonsignificant. These results are discussed in terms of a distinction between preattentive and attentional process…
The role of shame and guilt in social anxiety disorder
2021
Abstract Research suggests that shame and guilt may play a role in anxiety disorders. For social anxiety disorder (SAD), however, only a few studies investigated patients with the primary diagnosis of SAD. Thus, further research on shame and guilt in SAD is required. A secondary analysis of Data from the SOPHO-NET multicenter treatment study was performed. In a large sample of N = 495 patients with the primary diagnosis of SAD the relationship between shame and guilt with symptoms of social anxiety, depression, and interpersonal problems was examined by means of correlation analysis and additionally, a hierarchical linear regression analysis. To assess SAD, the German version of the Structu…
Specificity of Reading Self-Efficacy Among Primary School Children
2018
We investigated the specificity of reading self-efficacy among second- to fifth-grade children in Finland (N = 1,327). Bandura (1997 Bandura, A. (1997). Self-efficacy: The exercise of control. New York, NY: Freeman. [Google Scholar] ) theorized that efficacy beliefs can be assessed at different levels of specificity; however, empirical support for this view is scarce among young children. Efficacy beliefs targeting reading-related activities were assessed at three specificity levels (general, intermediate, and specific). Confirmatory factor analysis revealed that these specificity levels are separable, but correlated, and the structure was invariant across gender and grade level. Self-effic…
