WebDescription. Given a data.frame or matrix of n items and N observations and a list of the direction to score them (a keys.list with k keys) find the sum scores or average scores for each person and each scale. In addition, report Cronbach's alpha, Guttman's Lambda 6, the average r, the scale intercorrelations, and the item by scale correlations ... WebFeb 5, 2024 · Inter-item correlations were expected to be at values over 0.30, and we calculated the mean inter-item correlation (MIIC), which was expected to be between 0.15 and 0.50 . For subscales with an MIIC higher than 0.50, multicollinearity between items was tested by variance inflation factors (<4.0) and tolerance (>0.2) [ 29 ].

WebFind two estimates of reliability: Cronbach's alpha and Guttman's Lambda 6. Description. Internal consistency measures of reliability range from \omega_h to \alpha to \omega_t.This function reports two estimates: Cronbach's coefficient \alpha and Guttman's \lambda_6.Also reported are item - whole correlations, \alpha if an item is omitted, and … WebInter-item correlations address issues relating to a scale's fidelity of measurement, how well the instrument is measuring some construct (e.g., its internal consistency, … corporate social responsibility agenda
