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…

Anger is a topic that requires intervention from teachers, counsellors, psychologists, parents, and all communities. The expressions of anger are subjective and sometimes hard to identify. Thus, anger should be measured more objectively, while the expressions need to be examined closely. The purpose of this study is to provide valid confirmation…

Assessing the measurement model (MM) of self-report scales is crucial to obtain valid measurements of individuals' latent psychological constructs. This entails evaluating the number of measured constructs and determining which construct is measured by which item. Exploratory factor analysis (EFA) is the most-used method to evaluate these…

Psychological inflexibility has been associated with several mental health indicators. The Avoidance and Fusion Questionnaire for Youth (AFQ-Y) has been the most used measure to assess psychological inflexibility in adolescents, having been adapted to several different languages, including Portuguese. However, the short 8-item version of this…

The present investigation explored the psychometric validity of the five-item Gratitude Questionnaire (GQ-5) using a construct validation approach. Concerning within-network construct validity, results of item response theory (IRT) analysis via graded response model (GRM) showed that this scale could not discriminate individuals who score high in…

This article aimed to establish the psychometric properties of the Chinese version of the Subjective Happiness Scale (SHS-C) and to investigate the convergence between SHS-C and multidimensional subjective well-being (MSWB). A total of 543 college students completed the following measures: the SHS-C, the MSWB scale, Rosenberg's self-esteem scale,…

In the current article, we describe the development and validation of a self-report measure of self-generated stress and its associations with measures of perfectionism, self-criticism, and distress. The Self-Generated Stress Scale is a seven-item inventory that taps the tendency to see oneself as someone who generates and adds to existing…

Although it has been suggested that social network site (SNS) use motives are one of important determinants of SNS addiction, there has not been yet a scale to assess them. The aim of this study was to examine psychological properties of a newly developed Social Network Site Use Motives Scale (SUMS) in a college student sample. The SUMS was…

The "Psychological Sense of School Membership" (PSSM) scale has been used for more than 20 years to measure students' sense of school belonging, yet its psychometric properties have had limited examination with pre-adolescent children. This study investigated the utility and psychometrics of the PSSM in three primary school samples from…

Affective factors such as the achievement emotions are considered critical for students' academic performance in STEM degree programmes and careers. In this study, a reciprocal causation model was tested between two affective factors: enjoyment and anxiety, and organic chemistry course performance. Each variable was measured three times in four…

Research on perfectionism with the Almost Perfect Scale-Revised (APS-R) distinguishes adaptive perfectionists versus maladaptive perfectionists based primarily on their responses to the 12-item unidimensional APS-R Discrepancy subscale, which assesses the sense of falling short of standards. People described as adaptive perfectionists have high…

A large number of studies document that children differ in the degree they are shaped by their developmental context with some being more sensitive to environmental influences than others. Multiple theories suggest that "Environmental Sensitivity" is a common trait predicting the response to negative as well as positive exposures.…

The concurrent criterion validity of the Ausburg Multidimensional Personality Instrument (AMPI) clinical scales was examined. The AMPI and several scales purportedly measuring the same or similar constructs as those of the AMPI clinical scales were administered to two samples of college students (N = 134 and N = 118). The correlations between the…

Social support has been shown to be a significant protective factor in the lives of adolescents and has been linked to numerous health and psychological outcomes. Spirituality and religion have also been demonstrated to have similar effects on a host of outcomes. The current study further analyzed the link between these two constructs from a…

Researchers of the gifted have traditionally advanced the theory, though they are often without data to support it, that an association between intellectual and/or creative giftedness and mood disorders exists. This assumed association is often referred to as the "mad genius theory." This article explores the origins and development of…
