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 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…

Four maltreatment items were examined from Wave III (N = 13,516) of the National Longitudinal Study of Adolescent Health. Item analysis, confirmatory factor analysis, cross-validation, reliability estimates, and convergent validity coefficients strongly supported the validity of using the four items as a unidimensional composite. Implications for…

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…

Test-retest data on Super's Work Values Inventory-Revised for a group of predominantly White ("N" = 995) women (mean age = 23.5 years, SD = 8.07) and men (mean age = 21.5 years, SD = 5.80) showed stability in mean-level scores over a period of 1 year for the sample as a whole. However, low raw score and rank order stability coefficients…

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…

Counselors conducting survey research have many item format options to contemplate. This study examined midpoint selection and the effect on reliability of including or excluding midpoint options, and using both positively and negatively worded items. Findings indicate that reliability can be affected by both midpoint options and reverse coding.…

Although often ignored, reliability is critical when interpreting study effects and test results. Accordingly, this article focuses on the most commonly used estimate of reliability, internal consistency coefficients, with emphasis on coefficient alpha. An interpretive framework is provided for applied researchers and others seeking a conceptual…

Comparability of two forms of the CCTST is evaluated. Data are compared with a previously reported study; relationships to comparable tests are considered. Evidence indicates low internal-consistency reliability estimates, a lack of comparability, and poor construct validity for Forms A and B of the CCTST. (Author/EMK)

Technical characteristics of the Reading Essential Skills Screener-Elementary Version (RESS-E; B. T. Erford, G. Vitali, R. Haas, & R. R. Boykin, 1995) were studied using 4 independent samples of boys and girls between the ages of 6 and 8 years. Evidence of internal consistency, test-retest reliability, decision efficiency, factorial validity,…
