Background: The multidimensionality of the academic self-concept in terms of domain specificity has been well established in previous studies, whereas its multidimensionality in terms of motivational functions (the so-called affect-competence separation) needs further examination.
Aim: This study aims at exploring differential effects of enjoyment and competence beliefs on two external validity criteria in the field of mathematics.
Sample: Data analysed in this study were part of a large-scale longitudinal research project. Following a five-wave design, math enjoyment, math competence beliefs, math achievement, and perceived math effort expenditure measures were repeatedly collected from a cohort of 4,724 pupils in Grades 3-7.
Method: Confirmatory factor analysis (CFA) was used to test the internal factor structure of the math self-concept. Additionally, a series of nested models was tested using structural equation modelling to examine longitudinal reciprocal interrelations between math competence beliefs and math enjoyment on the one hand and math achievement and perceived math effort expenditure on the other.
Results: Our results showed that CFA models with separate factors for math enjoyment and math competence beliefs fit the data substantially better than models without it. Furthermore, differential relationships between both constructs and the two educational outcomes were observed. Math competence beliefs had positive effects on math achievement and negative effects on perceived math effort expenditure. Math enjoyment had (mild) positive effects on subsequent perceived effort expenditure and math competence beliefs.
Conclusion: This study provides further support for the affect-competence separation. Theoretical issues regarding adequate conceptualization and practical consequences for practitioners are discussed.

Background: Motivational disturbances are a major harbinger for dementia, being associated with a two- to seven-fold higher conversion rate from mild cognitive impairment. However, there are currently no objective assessment methods for identifying motivational disturbances in older adults (OA). Here, we present preliminary findings from a larger study which aims to validate an objective behavioral measure of effort in OAs by investigating the effects of age, risk, and reward (gain vs.

There are limited economic evaluations of patient navigation in the US health care system and few have considered costs at various phases along the implementation spectrum. Having economic data, including costs and cost savings, can support sustainability of patient navigation programs.

Background: Abnormalities in effort-based decision-making have been consistently reported in major depressive disorder (MDD). Evidence indicates that metabolic factors, such as insulin resistance and dyslipidemia, which are highly prevalent in MDD, are independently associated with reward disturbances. Herein, we investigate the moderating effect of metabolic factors on effort-based decision-making in individuals with MDD.
