Multiple Group Models Group 2 (female) Group 1 (male) Equivalence of measurement coefficients H 0: Λ[1] = Λ[2] lambda 1 [1] = lambda 1 [2] df=2 lambda 2 [1] = lambda 2 [2] From last Friday 3
Multiple Group Models Other equivalence tests possible: 1. Equivalence of variances of latent variables H 0: PSI-1[1] = PSI-1[2] • This test will depend upon which ref. indicator used 2. Equivalence of error variances * 3. 4. H 0: Theta-eps[1] = Theta-eps[2] {entire matrix} df=3 *and covariances if there are correlated errors From last Friday 4
Multiple Group Models n Measurement model equivalence does not imply same mean levels ¨ Measurement model for Group 1 can be identical to Group 2, yet the two groups can differ radically in terms of level. Group 1 Group 2 Load mean n Always trust gov’t. 80 2. 3. 78 3. 9 n Govern. Corrupt -. 75 3. 8 -. 80 2. 3 n Politicians don’t care (where 1=agree strongly through 10=disagree strongly) n Example: From last Friday 5
Multiple Group Models • It is possible to have multiple group models with both common and unique items • Example: • Y 1 Both countries: We should always trust our elected leaders • Y 2 Both countries: If my government told me to go to war, I’d go • Y 3 Both countries: We need more respect for government & authority • Y 4 (US): George Bush commands my respect because he is our President • Y 4 (Canada) Paul Martin commands my respect because he is our Prime Minister We might expect (if measurement equivalence holds): lambda 1[1] = lambda 1[2] lambda 2[1] = lambda 2[2] BUT lambda 3[1] ≠ lambda 3[2] From last Friday 6
Multiple Group Models • Should be careful with the use of reference indicators (and/or sensitive to the fact that apparently non-equivalent models might appear to be so simply because of a single (reference) indicator • Example: Group 1 Group 2 Lambda-1 1. 0* Lambda-2 . 50 1. 0 Lambda-3 . 75 1. 5 Lambda-4 1. 0 2. 0 • These two groups appear to have measurement models that are very different, but…. From last Friday 7
Multiple Group Models Group 1 Group 2 Lambda-1 1. 0* Lambda-2 . 50 1. 0 Lambda-3 . 75 1. 5 Lambda-4 1. 0 2. 0 • These two groups appear to have measurement models that are very different, but…. If we change the reference indicator to Y 2, we find: Gr 1 Gr 2 Lambda 1 2. 0 1. 0 Lambda 2 1. 0* Lambda 3 1. 5 Lambda 4 2. 0 From last Friday 8

MULTIPLE GROUP MODELS: parameter significance tests n n n When a parameter is constrained to equality across 2 (or more) groups, “pooled” significance test (more power) Possible to have a coefficient non-signif. in each of 2 groups yet significant when equality constraint imposed Possible to have a coefficient that is not significant in each of two groups (e. g. , +ve coefficient, NS, in one group, -ve, NS, in another) yet the difference between the groups is statistically significant 13
Tests in 3+ groups n n 2 -group model can be extended to m groups (in theory, infinite number as long as minimum sample size requirements met in each group; in practice, some software packages have limits) Models: ¨ ¨ ¨ n Group 1=Group 2=Group 3 Group 1=Group 2≠Group 3 Group 1 ≠ Group 2≠Group 3 Must be careful about interpretation of Modification Indices ¨ In a model with [1]=[2]=[3] ≠ 0, then a MI will provide an indication of how much the model improve if the parameter constraint is removed in the mth group only (e. g. , MI in group 2 would test against a model in which the group 1 & group 3 {same} parameter are constrained to equality but the group 2 is allowed to differ) 14
MULTIPLE GROUP MODELS: Modification Indices (again) Group 1 MOD INDICES Lambda 1 3. 01 Lambda 2 1. 52 Lambda 3 3. 22 Model: LY[1]=LY[2]=LY[3] Group 2 MOD INDICES Lambda 1 4. 22 Lambda 2 3. 99 Lambda 3 5. 22 Group 3 MOD INDICES Free LY(2, 1) in group 3 but Lambda 1 89. 22 Lambda 2 6. 11 LY(2, 1) in group 1 = LY(2, 1) in group 2 Lambda 3 1. 22 15
When do we have measurement equivalence n STRONG equivalence: all matrices identical, all groups ¨ (might possibly exclude variance of LV’s from this … i. e. , the PHI or PSI matrices) ¨ n WEAKER equivalence (usually accepted) ¨ Lambda matices identical, all groups ¨ Theta matrices could be different (and probably are), either having the same form or not n WEAKER YET: ¨ Lambda matrices have the same form, some identical coefficients 16
Measurement coefficients, construct equation coefficients in multiple group models n We usually need the measurement equation coefficients to be equivalent in order to proceed with comparison of construct equation coefficients 17
Measurement coefficients, construct equation coefficients in multiple group models n n We usually need the measurement equation coefficients to be equivalent in order to proceed with comparison of construct equation coefficients For this reason, tests for measurement equivalence are usually not as rigorous as the “substantive” tests for construct equation coefficient equivalence (though instances of poor fit should be noted in any report of results) 18
LISREL PROGRAMMING FOR MULTIPLE GROUP MODELS Basics: “Stack” the groups (one program after the next) In DA statement of first group, specify total number of groups: e. g. , DA NG=2 NI=23 NO=1246 NI specification (# of input var’s) applies only to group 1 NO specification (# of observations) applies only to group 1 19
LISREL PROGRAMMING FOR MULTIPLE GROUP MODELS DA NG=2 … Specify group 1 model as usual Title for Group 2 DA statement group 2 NI= NO= CM FI= [location of group 2 cov mtx] SE 13468/ LABELS [optional] MO NY= NX= NK= NE= + special options for matrix specification OU (as usual) 20
LISREL PROGRAMMING: MULTIPLE GROUPS MO specification: LY=PS same pattern as prev. group - for example, if group 1 specifies 2 LV’s with first three indicators on LV 1, next 6 on LV 2, this same specification will be copied to group 2 LY= IN invariant - same pattern and all free coefficients in this matrix constrained to equality with corresponding coefficients in previous group 21
LISREL PROGRAMMING: MULTIPLE GROUPS Adding equality constraints to a matrix that is otherwise allowed to differ from the same matrix in a previous group: Group 1 (e. g. ) LY=FU, FI VA 1. 0 LY 2 1 FR LY 2 1 LY 3 1 LY 4 1 Group 2 LY=PS EQ LY 1 2 1 LY 2 2 1 EQ LY 1 3 1 LY 3 1 22
LISREL PROGRAMMING: MULTIPLE GROUPS Releasing equality constraints on a single parameter when matrix is otherwise specified as Invariant: Group 2: LY=IN FR LY 4 1 LY remains invariant except for parameter LY(4, 1) 23
