WebApr 29, 2024 · The inter-item correlation range from 0.6 - 0.16 with an average of .10. I interpreted these results as a low degree of homogeneity, causing the Cronbach's alpha to decrease. This means that the items are not appropriate for measuring a construct unidimensionally. Further, I also calculated the total-item correlation. WebAverage inter-item correlations The calculations on average inter-item correlation between the seven questionairre items (Q1 - Q7) showed that almost all items correlate with the others in a reasonably restricted range of 0.4 to 0.5, indicating good consistency in inter-item correlation.

WebThe most common way for finding inter-item consistency is through the formula developed by Kuder and Richardson (1937). This method enables to compute the inter-correlation of the items of the test and correlation of each item with all the items of the test. J. Cronbach called it as coefficient of internal consistency. Webdengan menggunakan Inter-item Consistency Reliability yang melihat Cronbach’s coefficient alpha sebagai koefisien dari reliabilitas. Cronbach’s alpha adalah koefisien reliabilitas yang menunjukkan bagaimana bagian-bagian dari suatu set berkorelasi secara positif satu sama lainnya (Sekaran, 2003: 307).

WebInternal consistency reliability is a measure of reliability used to evaluate the degree to which different test items that probe the same construct produce similar results. Average inter-item correlation is a subtype of internal consistency reliability. It is obtained by taking all of the items on a test that probe the same construct ... WebInter-item consistency was evaluated based on Cronbach’s alpha and item to total correlations. Validity of scores was evaluated based on known-groups comparisons (age, number of health problems, symptom severity). The strength of a single, general factor was evaluated using a bi-factor model.
