This paper investigated consequences of measurement error in the pretest on the estimate of the treatment effect in a pretest-posttest design with the analysis of covariance (ANCOVA) model, focusing on both the direction and magnitude of its bias. Some prior studies have examined the magnitude of the bias due to measurement error and suggested…

In the context of Bayesian factor analysis, it is possible to compute plausible values, which might be used as covariates or predictors or to provide individual scores for the Bayesian latent variables. Previous simulation studies ascertained the validity of mean plausible values by the mean squared difference of the mean plausible values and the…

Intelligence has been declared as a necessary but not sufficient condition for creativity, which was subsequently (erroneously) translated into the so-called threshold hypothesis. This hypothesis predicts a change in the correlation between creativity and intelligence at around 1.33 standard deviations above the population mean. A closer…

We test children's distributive and collective sentence interpretations and the variables that predict them. In our first experiment, we establish that adult English collective sentences with "the" or "some" in the subject are categorically collective in their interpretations. We further demonstrate that children's collective…

The demand-resource framework is widely used to predict burnout in occupational context. This cross-sectional study aimed to explore the links of school demands and resources to student burnout. Six hundred and ninety-six Hungarian students from secondary schools participated in the data collection using online survey method in classrooms.…

We aimed to model the direct effects of the theorized relationships of academic self-efficacy, computer use self-efficacy, learning management system self-efficacy, internet and information-seeking self-efficacy, and online learning self-efficacy using structural equation modeling. The study proves that academic self-efficacy has positive…

This study utilises a holistic approach of positive psychology (PP) in the second language acquisition (SLA) domain to test a model of willingness to communicate in English language (L2WTC) among 328 Saudi learners. The model examines how potential connections among learners' negative emotions (anxiety and boredom), positive emotions (enjoyment…

Spirituality is a phenomenon which continues to attract much interest in the Western culture. Throughout the years, it has changed in form and developed in understanding. It has become unprecedentedly broad and embraced by many people, even those who do not consider themselves to be religious. Indeed, spirituality is a subject of debate within…

The main aim of this research is; to propose and test a model of structural equality that examines career adaptability of psychological counselors, career calling and skills used in the fields of vocational identity experience for psychological counselors. This research was designed as a causal pattern. 231 volunteer psychological counselors…

This study examined the structural relationship between teachers' career adaptability, emotional intelligence, striving for goals, and setting life goals. We hypothesized that emotional intelligence would predict career adaptability, and that this relationship would be mediated by striving for goals and setting life goals. A cross-sectional survey…

The gender gap continues to exist in physics education. The author examines the gender-related differences in the relations and strengths among personal epistemologies, motivation, and achievement in physics among Turkish high school students. Established questionnaires were used to identify students' personal epistemologies, motivations and…

Interactions across campus have long been documented as an important component of understanding the college student experience. This is especially salient in relation to interactions with faculty and peers during a student's first year, when susceptibility for departure is high. However, it is likewise critical to understand how distinctive types…

This study examines the factors influencing friendship quality during emergent adulthood. Data were collected on a sample of 393 college students (age range 18-22, M = 20.01). Nine multi-item measures were used as indicators in this study. Seven scales were drawn from the Battery of Adolescent Measures (Benson & Faas, 2014). The other two were…

Previous research has generally focused on understanding individual variation in either on-line processing or off-line comprehension even though some theories explicitly link difficulty in processing to comprehension problems. The goal of the current study was to examine individual variation in performance both during on-line and off-line reading…

This study examined the relationship between coping strategies, dispositional optimism, academic burnout and academic performance using structural equation modelling. Data were collected from a sample of 532 Spanish undergraduate students. Participants completed a battery of questionnaires including the LOT-R to assess optimism, CSI for the…
