FOLDER: "MainAnalysis_Wave1"
******************************
These are the do-files for generating the main results described in the paper "Remittances and risk of Major Depressive Episode and Sadness Among New Legal Immigrants to the United States".

****Under the folder "1_CreateVariables"**** 
Subfolder 1: 
-Wave 1 sociodemographic, income, and remittances data are merged separately

Subfolder 2:  
-Resondent and spouse income variables are created
-Respondent & household ID are extracted
-Household income variable is created
-Respondent and spouse remittances data are merged
-Sociodemographic, income, and remittances data are merged together 

Subfolder 3: 
-Variables for remittances given by the respondent's household and remittances received by the respondent's household are created. 

Subfolder 4:
-Sociodemographic and health variables are created, including the dependent variables, major depressive episode (MDE) and sadness. 
-Flags are created that capture the number of cases with missing values across study measures.
-Variables are transformed as needed. 
***************************
***************************

****Under the folder "2_MultipleImputation"****
-Dataset with study variables extracted
-Multiple imputation of missing data is performed
-Post imputation management of some variables  
***************************
***************************

****Under the folder "3_Analysis"****
Subfolder 1: 
-Reference groups for categorical variables are set

Subfolder 2:
Analysis are performed on the full sample.
-Sample characteristics
-Sociodemographic correlates of MDE and sadness
-Main & conditional effects of remittances (continuous) on MDE and sadness
-Main & conditional effect of remitted (yes/no) on MDE and sadness

Analysis are perfomed on the sample of remitters only
-Main & conditional effects of remittances (continuous) on MDE and sadness

Significant interaction (remitters only) is graphed
-The effect of remittances (continous) on sadness varies by visatype.

FOLDER: "SupplementaryAnalysis_Wave1&2"
*******************************************
These are the do-files for generating the supplementary results described in the paper.

****Under the folder "1_CreateVariables"**** 
Subfolder 1: 
-Wave 2 sociodemographic, income, and remittances data are merged separately

Subfolder 2:  
-Respondent & household ID are extracted
-Sociodemographic, income, and remittances data are merged together 

Subfolder 3: 
-Additional wave 1 variables and wave 2 dependent variable (MDE and sadness) are created.   ***************************
***************************

****Under the folder "2_MultipleImputation"****
-Wave 1 dataset (from the main analyses above) & wave 2 dataset with study variables extracted
-Wave 1 and wave 2 datasets merged
-Multiple imputation of missing data is performed
-Additional management of some varibles (post imputation) is performed. 
***************************
**************************

****Under the folder "3_Analysis"****
Subfolder 1: 
-Reference groups for categorical variables are set

Subfolder 2:
Analysis are performed on the full sample. Wave 1 independent variable (remittances)
is regressed on wave 2 dependent variables (MDE and sadness) net of wave 1 sociodemographic
and health controls. 
-Sample characteristics
-Sociodemographic correlates of MDE and sadness
-Main & conditional effects of remittances on MDE and sadness
-Main & conditional effect of remitted (yes/no) on MDE and sadness

Analysis are perfomed on the sample of remitters only
-Main & conditional effects of remittances (continuous) on MDE and sadness
