Constructed Data - 2015-2001 MHAS Cognitive Function Measures Scoring and Classification

Since the beginning of the study, the MHAS includes a section to assess cognitive function in direct and proxy interview. The constructed data files include all constructed scores for the different cognitive function tasks included in the study across the four waves (2001, 2002, 2012 and 2015). It also provides the normative standards and z-scores for each task as well as the composite score.

SimpleMHAS (ENASEMsimple)

The SimpleMHAS (ENASEMsimple) is a longitudinal dataset that includes every person interviewed atleast once for MHAS and a reduced selection of variables (81 excluding identifiers, information about the interview, and sampling weights) versus the full MHAS database. it includes a smaller selection of variables for ease of use by two groups in particular: students and researchers new to MHAS. For more detailed information, please refer to the descriptive document.

MHAS Created Variables

The MHAS created variables is a set of data files for each wave of the study. Each of these data files has a wide format, with the unit of observation the individual subject. The naming of the variables is consistent across waves to facilitate the comparison. In addition, each data set includes the necessary identifiers to be able to complete a merge with all the other created data files as well as with the raw data across and within waves.
