The present study presents preliminary evidence regarding the reliability and validity of the Multidimensional Inventory of Black Identity (MIBI). The MIBI consists of 7 subscales representing 3 stable dimensions of African American racial identity (Centrality, Ideology, and Regard). Responses to the MIBI were collected from 474 African American college students from a predominantly African Ame...

Recent literature models leadership as the process of communication where the rhetorical signals of leaders facilitate followers’ coordination. While studies exist that explored the effects of leadership in experimental settings, there remains a lack of empirical research on the effectiveness of informational tools in real political environments. Using quantitative text analysis of federal and ...

In this paper, Douglas MacInnes examines the validity of a measure of irrational beliefs, the Shortened General Attitude and Belief Scale (SGABS). He examines the overall correlation between the various subscales of the measure, the criterion validity and construct validly of the instrument, as well as internal consistency. Results show that the measure had good validity and was a useful measur...

Prevention and intervention work done within community settings often face unique analytic challenges for rigorous evaluations. Since community prevention work (often geographically isolated) cannot be controlled in the same way other prevention programs and these communities have an increased level of interpersonal interactions, rigorous evaluations are needed. Even when the ‘gold standard’ ra...

The aim of this work was to update the validation of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of Spanish adolescents. To achieve this, one study with a sample of 1489 students in secondary education, of ages 14 to 17 years, were carried out. The psychometric properties of EDAS were examined through confirmatory factor analysis, reliability (Cronbach's alpha), temporal stabilit...

[Purpose] This study aimed to examine the validity and internal consistency of the Japanese version of a performance evaluation tool for activities of daily living (ADL) based on the modified Barthel Index (PET-MBI) among elderly people at home. [Subjects] The subjects were elderly people living at home in Japan. [Methods] A cross-sectional study was performed at five home care facilities for e...

Questionnaires are commonly used to measure attitudes toward systems and perceptions of search experiences. Whilst the face validity of such measures has been established through repeated use in information retrieval research, their reliability and wider validity are not typically examined; this threatens internal validity. The evaluation of self-report questionnaires is important not only for ...

OBJECTIVE This study aimed to evaluate the internal consistency reliability and construct validity of the Fitzpatrick Skin Type Scale during radiation therapy in a cohort of women receiving treatment for breast cancer. METHOD The assessment of the scale was performed as a nested study within a randomised controlled trial of two creams used for radiation therapy skin care for breast cancer pat...

Single-case research designs provide a rigorous research methodology for documenting experimental control. If single-case methods are to gain wider application, however, a need exists to define more clearly (a) the logic of single-case designs, (b) the process and decision rules for visual analysis, and (c) an accepted process for integrating visual analysis and statistical analysis. Considerat...
