Using item response theory, we examined the psychometric properties of scores on the Trauma-Informed Practice Scales -- Supervision Version (TIPS-SV) -- a unidimensional measure of supervisees' perceptions of their supervisors' adherence to trauma-informed supervision -- in a sample of 312 supervisees. Implications for research and supervision…

Psychometric properties of measures of hope and meaning in life in Spanish among Latina/o college students were investigated. A confirmatory factor analysis was used to evaluate structural validity of instruments. Findings provided support for the reliability and validity of scores on the Disposition Hope Scale and Meaning in Life Questionnaire…

Researchers developed and initially validated a client-report measure of counselors' cultural humility, entitled the Cultural Humility and Enactment Scale (CHES). The sample includes 434 adults recruited from web-based surveys. Exploratory factor analyses were performed to examine the initial factor structure of the CHES. Bivariate correlations…

The psychometric properties of the 2 versions of the Junior Metacognitive Awareness Inventory were examined with Singapore student samples. Other than 2 misfitting items and an underutilized response scale, Rasch analysis demonstrated that the instruments have good measurement precision, and no differential item functioning was detected across…

The purpose of this study was to investigate psychometric properties of the Children's Depression Inventory within a nonclinical and longitudinal sample (8th and 12th grades). Using the Rasch rating scale, most items represented one dimension. There was adequate separation among items and no overlap between ranges of item difficulties with latent…

The Screening Test for Emotional Problems-Teacher Version (STEP-T) was designed to identify students aged 7-17 years with wide-ranging emotional disturbances. Coefficients alpha and test-retest reliability were adequate for all subscales except Anxiety. The hypothesized five-factor model fit the data very well and external aspects of validity were…

This study describes the development and psychometric properties of the Counseling Supervisor's Behavior Questionnaire, designed to assess the specific behaviors of supervisors, which can be observed by supervisees during supervision sessions. Factor structure, construct and concurrent validity, and internal consistency reliability of the…

This study aimed to develop and validate the Attitude Toward Calculus Inventory (ATCI). Results from three studies are reported that establish the reliability and validity of this instrument. An examination of the factor structure confirms that student attitudes can be explained in terms of four factors: self-confidence, value, enjoyment, and…

This article describes the development of the Student Engagement in School Success Skills instrument including item development and exploratory factor analysis. The instrument was developed to measure student use of the skills and strategies identified as most critical for long-term school success that are typically taught by school counselors.

The Self-Efficacy Parent-Report Scale was designed to assess parent perceptions of self-efficacy of their children aged 7 to 17 years. Internal aspects of validity indicated a marginal fit of the data to the unidimensional model. External facets of validity indicated the Self-Efficacy Parent-Report Scale had excellent convergent and discriminant…

The psychometric properties of measures of self-efficacy for the six themes of Holland's theory were examined using item response theory. Item and scale quality were compared across levels of the trait continuum; all the scales were highly reliable but differentiated better at some levels of the continuum than others. Applications for adaptive…

The authors investigated the Chinese version of the Beck Depression Inventory-II (BDI-II-C; Chinese Behavioral Science Corporation, 2000) within the Rasch framework in terms of dimensionality, item difficulty, and category functioning. Two underlying scale dimensions, relatively high item difficulties, and a need for collapsing 2 response…

Traditional Item Selection Rules (TISRs) were compared to Intervention Item Selection Rules (IISRs) on the same set of alcohol attitude items from archival data, producing scales with differing psychometric properties. A cross-validation study was run. Guidelines for selecting change-sensitive items, problems and advantages of IISRs are…

This study compares the ability of 2 item-selection methodologies, principal components analysis and intervention item selection rules, to capture client changes on a 56-item self-report checklist. Scales formed with the intervention-sensitive items evidence larger effect sizes and reliability estimates. (Contains 26 references and 3 tables.)…

Differential item functioning (DIF) in the Multidimensional Self Concept Scale (B. A. Bracken, 1992) was evaluated using 2 different methods to identify and describe DIF. Of 149 items from the Multidimensional Self Concept Scale, 42% exhibited gender DIF. Nonuniform, crossover DIF was evident in items throughout the instrument.
