EFA with low communalities for some items. Results: ROC analysis indicated the excellent convergent validity of SF-12 MCS with the CESD-10 threshold for identifying probably clinically significant depression, with the area under curve ranged from 0.81 to 0.85.

Provides Model Fit estimate. Higher communalities are better. For variance-based structural equation modeling, such as partial least squares, the Fornell-Larcker criterion and the examination of cross-loadings are the dominant approaches for evaluating discriminant validity. Bootstrapping estimates of the mean difference indicated no significant difference in the optimal cutoff scores between these age cohorts. For instance, Item 1 might be the statement “I feel good about myself” rated using a 1-to-5 Likert-type response format. So, this must be a good way to identify our group of interest, right? Convergent validity tests that constructs that are expected to be related are, in fact, related. If you need to work with formative factors, either use a Partial Least Squares approach (see PLS section), or create a score (new variable) for each set of formative indicators. Conclusion: SF-12 is a widely adopted measure to capture the health profile of Chinese population. A critical assumption of the EFA is that it is only appropriate for sets of non-nominal items which theoretically belong to reflective latent factors. Construct validity’s main idea is that a test used to measure a construct is, in fact, measuring a construct. An EFA should always be conducted for new datasets. There are three main methods for factor extraction. Objectives: The purpose of the current study was to assess the reliability as well as the convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP). Specifying formative versus reflective constructs is a critical preliminary step prior to further statistical analysis. Researchers are encouraged to develop and report convergent validity data. 411 An Alternative Procedure for Assessing Convergent and Discriminant Validity Donald R. Lehmann Columbia University This paper presents a simple procedure for estab- lishing convergent and discriminant validity.The method uses ordinary least-squares regression (OLS) with the correlations between measures as the depen- dent variable. In the figure below, we see four measures (each is an item on a scale) that all purport to reflect the construct of self esteem. Convergent validity tests that constructs that are expected to be related are, in fact, related. Discriminant validity (or divergent validity) tests that constructs that should have no … If all the "Trust" variables in the pattern matrix above loaded onto a single factor, we may have to abstract a bit and call this factor "Trust" rather than "Trust in Agent" and "Trust in Company". Bootstrapping estimates of the mean difference indicated no significant difference in the optimal cutoff scores between these age cohorts. Factor structure refers to the intercorrelations among the variables being tested in the EFA. Do you know of some citations that could be used to support the topics and procedures discussed in this section? PAF is only analyzing common factor variability; removing the uniqueness or unexplained variability from the model. Cronbach's alpha should be above 0.7; although, ceteris paribus, the value will generally increase for factors with more variables, and decrease for factors with fewer variables. The optimal cutoff scores for depression among the younger to middle age group, late middle age group and older age group were 48.1, 50.2 and 50.2, respectively, with sensitivities ranged from 77 to 83 % and specificities ranged from 73 to 78 %. Convergent validity, along with discriminant validity, is a subtype of construct validity. Here is how you know whether you're working with formative or reflective constructs: An example of formative versus reflective constructs is given in the figure below. We propose an IHS cutoff score of 56 instead of 69 for diagnosing hyperacusis. MID thresholds derived from this study are largely in line with previously established thresholds with some minor adjustments. Now I am using the PLS for analyzing my data and I am in the measurement model stage. T1 - Interpreting SF-12 mental component score: an investigation of its convergent validity with CESD-10. How to use convergent in a sentence. Unlike convergent validity, where we are interested in the extent to which the scores converge (i.e., we want to see a strong relationship between the two scores on the same construct), with divergent validity, we are interested in the extent to which the scores diverge (i.e., we want to see little or no relationship between the two scores from the two constructs).
