The Perfectionism Social Disconnection Model (PSDM) and the Existential Model of Perfectionism and Depressive Symptoms (EMPDS) are promising models of perfectionism and psychopathology. However, research examining suicide ideation within the PSDM is scarce, and no research has examined suicide ideation as an outcome in the EMPDS. Moreover, tests…

The extant literature on regret as motivation for behavior presents inconclusive results, collectively. While it has often been agreed that regret motivates reparative action, most studies from the past 14 years indicate that regret may motivate either detrimental actions or, more commonly, no action at all. There also appears to be no published…

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

Most research on children's play takes a context-dependent, adult-focused observational approach to the measurement of play. The current two studies present the development and psychometric properties of the Child Self-Report Playfulness (CSRP) scale, which was presented via "puppet-show" to two samples of children. Study 1, across 98…

The directionality and longitudinal course between perfectionism and academic achievement throughout adolescence remains unclear as most studies rely on cross-sectional or short-term data and many examine these associations in university students who do not represent the full spectrum of learners. Moreover, most studies are hampered by their…

Perfectionistic automatic thoughts have been linked with depressive symptoms in numerous cross-sectional studies, but this link has not been assessed in longitudinal research. An investigation with two timepoints was conducted to test whether perfectionistic automatic thoughts, as assessed by the Perfectionism Cognitions Inventory (PCI), are…

Informed by the biological sensitivity to the context (BSC) theory, this multimethod, longitudinal study sought to examine how family context may be associated with the development of child sensory processing sensitivity (SPS) over a year. Participants were 235 young children (M[subscript age] = 2.97 at the first measurement occasion, 55.3% were…

Financial risk tolerance is an important personal characteristic that is widely used by financial professionals to guide the development and presentation of client-centered recommendations.

Diverse mechanisms account for the familial aggregation of certain personality traits and externalizing psychopathology. We explored the roles of positive and negative parenting as mediators of longitudinal associations between parents' maladaptive personality traits and their children's inattention/hyperactivity problems. We collected self,…

Numerous studies consider competition and jealousy within an evolutionary framework, yet less is known about the relation between aggression vis-à-vis hypercompetitiveness (i.e., competing to win) and jealousy. We investigated the longitudinal relations between hypercompetitiveness, jealousy, and aggression and the moderating role of gender in a…

This study examined the mediating role of emotional availability in the relation between parent positive personality and toddler problem behavior. The sample comprised 654 twins at 12 and 32 months. Primary caregivers (>95% mothers) completed six measures indexing parent positive personality assessed at 12 months, and emotional availability and…

This study aimed to examine the effect of attachment security in 17-month-olds on their peer play interactions and behavioural problems at ages 4 and 6 years, respectively, in Korea. By employing structural equation modelling, we analyzed the data of 183 children and their mothers, which were extracted from the Panel Study on Korean Children…

The aim of the present study was to examine the cross-cultural differences in the relationship between personality traits and neurasthenia across early adolescence. The participants were from Australia and China. Adolescents' personality was measured by the Junior Eysenck Personality Questionnaire, and neurasthenia was measured by the Somatic and…

Background: Many empirical investigations focus on how personality traits and academic motivation are related to academic achievement. Regarding the personality traits described in the five-factor model, prior research has shown associations between openness to experience and language achievement in particular. Following the principle of trait…
