The purpose of this study was to investigate the Type I Error findings and power rates of the methods used to determine dimensionality in unidimensional and bidimensional psychological constructs for various conditions (characteristic of the distribution, sample size, length of the test, and interdimensional correlation) and to examine the joint…

The true spirit of education involves psychosocial grooming and character building of learners. Teacher's efficacy plays a vital role in achieving educational objectives. The effectiveness of teachers is usually evaluated through the academic grades of their students. Teacher's efficacy, however, is originally the ability of a teacher to improve…

We evaluated the Portuguese version of the Anxiety Sensitivity Index 3 (ASI--3--PT). Results of a confirmatory factor analysis (N = 603; 65.3% women, M age = 28.55, SD = 10.42) confirmed multidimensionality of the construct and the receiver operating characteristic confirmed the discriminant capacity of the measure between clinical and nonclinical…

Self-report inventories are commonly administered to measure social-emotional learning competencies related to college and career readiness. Inattentive responding can negatively impact the validity of interpreting individual results and the accuracy of construct validity evidence. This study applied nine methods of detecting insufficient effort…

Vocabulary researchers have started expanding their assessment toolbox by incorporating timed tasks and psycholinguistic instruments (e.g., priming tasks) to gain insights into lexical development (e.g., Elgort, 2011; Godfroid, 2020b; Nakata & Elgort, 2020; Vandenberghe et al., 2021). These timed sensitive and implicit word measures differ…

The purpose of this study was to develop a valid and reliable "Environmental Attitude Scale" (EAS) for secondary school (5th, 8th grade), high school (11th) and undergraduate college students. The reliability and validity studies of the scale were carried out in three different countries (Finland, USA and Turkey). The sampling size was…

Consequently, it is critical to have reliable and valid tools to measure this important variable accurately. The Preschool version of the Dimensions of Mastery Questionnaire (DMQ)…

The validity of the Multidimensional School Anger Inventory (MSAI) was examined with adolescents from 5 Pacific Rim countries (N = 3,181 adolescents; age, M = 14.8 years; 52% females). Confirmatory factor analyses examined configural invariance for the MSAI's anger experience, hostility, destructive expression, and anger coping subscales. The…
