In recent years, some models for binary and graded format responses have been proposed to assess unipolar variables or "quasi-traits." These studies have mainly focused on clinical variables that have traditionally been treated as bipolar traits. In the present study, we have made a proposal for unipolar traits measured with continuous…

American Educational Research Association (AERA) standards stipulate that researchers show evidence of the internal structure of instruments. Confirmatory factor analysis (CFA) is one structural equation modeling procedure designed to assess construct validity of assessments that has broad applicability for counselors interested in instrument…

Many psychological scales written in the Likert format include reverse worded (RW) items in order to control acquiescence bias. However, studies have shown that RW items often contaminate the factor structure of the scale by creating one or more method factors. The present study examines an alternative scale format, called the Expanded format,…

The study objectives were to develop, trial and evaluate a cross-cultural adaptation of the Adaptive Behavior Assessment System-Second Edition Teacher Form (ABAS-II TF) ages 5-21 for use with Indigenous Australian students ages 5-14. This study introduced a multiphase mixed-method design with semi-structured and informal interviews, school…

The Stirling Children's Well-being Scale (SCWBS) was developed by the Stirling Council Educational Psychology Service (UK) as a holistic, positively worded measure of emotional and psychological well-being in children aged eight to 15 years. Drawing on current theories of well-being and Positive Psychology, the aim was to provide a means of…

Of the several measures of optimism presently available in the literature, the Life Orientation Test (LOT; Scheier & Carver, 1985) has been the most widely used in empirical research. This article explores, confirms, and cross-validates the factor structure of the Chinese version of the LOT with ordinal data by using robust weighted least…

Previous systematic reviews indicate a lack of reporting of reliability and validity evidence in subsets of the medical education literature. Psychology and general education reviews of factor analysis also indicate gaps between current and best practices; yet, a comprehensive review of exploratory factor analysis in instrument development across…

Factor analysis of the Bell Object Relations Inventory items produced four subscales interpreted to be underlying dimensions of object relations. The implications of the subscales, and the potential of the instrument for empirical examination of theoretical assumptions about the object relations ego function and its components, are discussed.…

A method for the construction of scales which combines the rational (or intuitive) approach with an empirical (item analysis) approach is presented. A step-by-step procedure is provided. (Author/JKS)

In the original item factor analysis of the Adjective Check List, evidence was found for seven main factors. In this cross-validation study, five of the seven factors were replicated: social desirability, introversion/extroversion, internal discomfort, cognitive independence, and social attractiveness. Tables with factor loadings are presented.…

Tested the California Psychological Inventory Socialization scale's dimensionality on three groups of male and female, criminal or noncriminal subjects. The fit of a one-factor model for all three groups was tested in a simultaneous factor analysis for several populations, and good fit was obtained. (Author)

Examined the psychometric properties of the Multidimensional Health Locus of Control (MHLC) Scales with alcoholic patients (N=100). The three MHLC Scales appear to measure largely independent dimensions of locus of control beliefs specifically related to health. Factor analyses suggest that the instrument is factorily valid. (Author/JAC)

The 72-item Erikson Psychosocial Stage Inventory (EPSI) was factor analyzed for a group of 534 university freshmen and sophomore students. Seven factors emerged, which were labeled Initiative, Industry, Identity, Friendship, Dating, Goal Clarity, and Self-Confidence. Item's representing Erikson's factors, Trust and Autonomy, were dispersed across…

Examines the dimensions underlying the applied problem-solving process and describes the development of a problem-solving instrument based on factor-analysis results. Delineates initial reliability and validity estimates of the instrument. Discusses future research implications and provides a research instrument easily administered and scored.…

Examines reliability and validity of two versions of Hispanic Stress Inventory (HSI), a new instrument to assess psychosocial stress among Hispanic adults. Subscale scores found to correlate highly with criterion measures of distress. Tests showed internal consistency and supported HSI reliability. Need for further evaluation discussed. (TES)
