Overall, psychometric tests based on various validity (convergent, known-groups, concurrent) and reliability (Cronbach α) analyses confirmed previous findings in that FACT-M performs well in MCC patients. 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. This cross-cultural study investigates antecedents of travel-related user-generated content (UGC) in China and Spain. 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 %. Content validity, test–retest reliability, internal consistency reliability, clinically important difference, clinically important responder, convergent validity, and known-group validity were evaluated using correlational and regression methods from phase 2b data from US adults with moderate-to-severe AD who were treated with abrocitinib. Higher communalities are better. This option is not recommended as it is usually the last course of action to take. ... Convergente constructvaliditeit: validiteit waarmee wordt bepaald of een gemeten variabele positief correleert met variabelen zoals theoretisch verwacht mag worden. 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. 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. Considers all of the available variance (common + unique) (places 1’s on diagonal of correlation matrix). The first method is to examine the pattern matrix. Evidence for strong support of the item’s convergent validity can be obtained by reviewing their squared factor loadings, which are desired to achieve the cut-off level of .5 or higher. This is evident by the factor loadings. Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables. EFA that results in too many or too few factors (contrary to expected number of factors). Future study is warrant to examine the diagnostic validity of the SF-12 MCS by using gold standard to assess clinical depression. 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. Direction of causality is from measure to construct, No reason to expect the measures are correlated, Direction of causality is from construct to measure. A correlation coefficient will also be determined for discriminant validity between the IOI-S and MC-SDS/CSD-S. You can run the EFA using a more exploratory approach without regard to expected loadings. 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). Convergent validity can be established if two similar constructs correspond with one another, while discriminant validity applies to two dissimilar constructs that are easily differentiated. T1 - Interpreting SF-12 mental component score: an investigation of its convergent validity with CESD-10. Use when there is concern with prediction, parsimony and you know the specific and error variance are small. / Yu, Doris S.F. This is a sign of low correlation and is usually corroborated by a low pattern matrix loading. Squared factor loadings for all but one item (Be6, X 2 = .40) turned out to accomplish this threshold, as the majority of items demonstrated squared loadings in the .80s.

PAF is only analyzing common factor variability; removing the uniqueness or unexplained variability from the model. Campbell and Fiske (1959) state that evidence for convergent validity is provided where the coefficients of the reliability diagonal are consistently the highest in the matrix. I have found the best way to resolve this type of issue is to do a separate EFA with just the items from the offending factors. Receiver operating characteristics (ROC) analyses were performed to examine the convergent validity of SF-12 MCS against the CESD-10 threshold for probably clinically significant depression for the younger to middle-aged, late middle-aged and older population cohorts. EFAs are exploratory and they can be treated as such. As such, formative constructs should not be expected to properly factor in an EFA, and cannot be modeled appropriately in AMOS during a CFA. Convergent validity is a subcategory of construct validity.

N2 - Objective: To examine the convergent validity of Mental Component Scale of the Short-Form 12 (SF-12 MCS) with the Center for Epidemiologic Studies Depression Scale (CESD-10). Thanks! The convergent validity of the constructs was measured by using the average variance extracted and the composite reliability. Convergent and divergent validity. MID thresholds derived from this study are largely in line with previously established thresholds with some minor adjustments. However, after running the CFA with the full model (ignoring the EFA), I was able to retain all constructs by only removing a few items (and not the ones I expected based on the EFA!). What can you do about it? 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 %. Data on SF-12 MCS and the CESD-10 were extracted. Methods: Data were obtained from a household survey carried out in Hong Kong. We examined the convergent validity of the EuroQol-5 Dimension 3-level questionnaire (EQ-5D-3L) as a measure of quality of life in homeless adults with mental illness. 3. Illustrations indicate that the method This happens all the time when you extract based on eigenvalues. Low values indicate candidates for removal after you examine the pattern matrix. There is no right answer (this is statistics after all), but you do have a few options: 1. Interpreting SF-12 mental component score: an investigation of its convergent validity with CESD-10. If we measure alcoholism in this way, it seems likely that anyone who identifies as an alcoholic would respond with a yes to the question. Indruksvaliditeit (face validity): het feit dat men in de veronderstelling is dat de meting valide is. 3. The distinction between divergent and convergent thinking implies a dichotomy. 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. 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). 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". Generally, the smaller the sample size, the higher the required loading. We want to retain as much as possible and still be producing valid results. For a very rocky but successful demonstration of handling a troublesome EFA, watch my SEM Boot Camp 2014 Day 3 Afternoon Video towards the end. Sufficient/significant loadings depend on the sample size of your dataset. To establish convergent validity, you need to show that measures that should be related are in reality related. First, let’s say we’ve decided to measure alcoholism by asking people to respond to the following question: Have you ever had a problem with alcohol? Methods: Data were obtained from a household survey carried out in Hong Kong. Construct Validity: Convergent vs. Discriminant. Audiological measures were the pure-tone average threshold (PTA) and uncomfortable loudness levels (ULL). Data on SF-12 MCS and the CESD-10 were extracted. Convergent validity tests that constructs that are expected to be related are, in fact, related. I also bring this up because I ran an EFA recently and got something I could not salvage without hacking a couple constructs. We can see that in the pattern matrix above, we would need a sample size of 60-70 at a minimum to achieve significant loadings for variables loyalty1 and loyalty7. Work out this smaller EFA (by removing items one at a time that have the worst cross-loadings), then reinsert the remaining items into the full EFA. REF: Podsakoff, P.M., MacKenzie, S.B., Lee, J.Y., and Podsakoff, N.P. If you are unsure what construct validity is, we recommend you first read: Construct validity.Convergent validity helps to establish construct validity when you use two different measurement procedures and research … R… Wikipedia® is een geregistreerd handelsmerk van de Wikimedia Foundation, Inc., een organisatie zonder winstoogmerk. Exploratory Factor Analysis (EFA) is a statistical approach for determining the correlation among the variables in a dataset. Conclusion: SF-12 is a widely adopted measure to capture the health profile of Chinese population. Then, during the CFA, be sure to properly model the 2nd order factor with an additional latent variable connected to its sub-factors. Let’s say that the items from one or two constructs do not load as expected no matter how you manipulate the EFA. A two-stage stratified sampling method successfully interviewed 1795 adult subjects from 1239 households. A communality is the extent to which an item correlates with all other items. As we can see from the factor correlation matrix below, factor 2 is too highly correlated with factors 1, 3, and 4. What if you have discriminant validity problems - for example, the items from two theoretically different factors end up loading on the same extracted factor (instead of on separate factors). EFA with a 2nd order construct involved, as well as several first order constructs. Convergent validities above r = .70 are recommended, whereas those below r = .50 should be avoided. < 0.05) indicates matrix is not an identity matrix; i.e., the variables do relate to one another enough to run a meaningful EFA. METHODS . Sufficient/significant loadings depend on the sample size of your dataset. Convergent validity was assessed through correlations of BASC-PRS scale scores with scale scores on the Child Behavior Checklist/4-18 (CBCL/4-18; Achenbach, 1991b). So, this must be a good way to identify our group of interest, right? On the bottom part of the figure (Observation) w… Convergent Validity between the PUTS and Real-Time Urge Intensity. The value ranges from 0 to 1. Convergent validity tests that constructs that are expected to be related are, in fact, related. You can say to yourself, “Why am I doing an EFA? This option is acceptable, but will lead you to produce a model that is probably somewhat different from the one you had expected to end up with. The indicators for reflective constructs ar required to be correlated, whereas the indicators for formative constructs are not required to be correlated. Convergent Validity indicates how well a measure correlates with other measures that ostensibly measure the same thing. C onvergent validity and discriminant validity are commonly regarded as ways to assess the construct validity of a measurement procedure (Campbell & Fiske, 1959). Het gaat er dus om of het instrument op het oog valide lijkt te zijn. Yu, Chau Wai Elsie Yan, Choi Kai Chow, Research output: Journal article publication › Journal article › Academic research › peer-review. Convergent and discriminant validities are two fundamental aspects of construct validity. If it doesn't, then consider whether these two factors are actually just two dimensions or manifestations of some higher order factor. Then during the CFA, make sure to model the higher order factor properly by making a 2nd order latent variable. Factors that demonstrate sufficient face validity should be easy to label. A two-stage stratified sampling method successfully interviewed 1795 adult subjects from 1239 households. 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.
