Harmonized Databases

The harmonized databases project is the product of collaboration between the IGDC and the Herczeg Institute on Aging at Tel Aviv University. The project aimed to create a harmonized database that serves as a basis for an aggregated research paper comparing parallel variables from five large databases on populations of older adults in Israel. The process of harmonization yields a Common Data Base of variables from different databases which address similar topics even though they were created independently from each other and usually used different formats.

The project aimed to create a harmonized database that as a basis for an aggregated research paper comparing parallel variables from five large databases on populations of older adults in Israel. The process of harmonization yields a Common Data Base of variables from different databases which address similar topics, even though they were created independently from each other at the time, and usually used different formats. Access to the harmonized database is provided to researchers in the field of gerontology by the Israel Gerontological Data Center. The following is a list and a brief description of the databases included in the project:

 
1) CALAS (Cross-Sectional and Longitudinal Aging Study)
This is a nationally random-stratified sample of Israelis aged 75 or older, interviewed during 1989-1992. The total database includes 1369 self-respondents from the community and institutions. The CALAS conducted a multidimensional assessment of socio-demographic, physical, functional, cognitive, psychological, and social characteristics.

2) IMAS (the Israel Multi-disciplinary Aging Study)
This is a nationally random-stratified sample of Israelis aged 65 or older, interviewed during 1999-2001. The total database includes 721 self-respondents from the community. The IMAS conducted a multidimensional assessment of socio-demographic, physical, functional, cognitive, psychological, and social characteristics.

3) SHARE-Israel (the Israeli component of the Survey of Health, Ageing, and Retirement in Europe)
This is a nationally representative sample of Israelis aged 50 or older and their spouses regardless of age, interviewed during 2005-2006. The total Israeli database includes 2598 community dwellers in 1771 households. The SHARE conducted a multidimensional assessment of socio-demographic, physical, functional, cognitive, psychological, and social characteristics.

4) BSE (Biographical Survey of Elderly in Israel)
This is a convenience sample of Israelis aged 60 or older, interviewed during 2001-2003. The total database includes 776 community and institution dwellers. Participants answered to semi-structured questions about their life story, and completed socio-demographic and psychological indices. Additionally, about 1000 participants interviewed during 2008-2011 are expected to be integrated within this database.

5) LSWBS (The Life-Span Well-Being Survey in Israel)
This is a convenience sample of Israelis aged 60 or older, interviewed during 1985-2003. The total database includes 7221 community and institution dwellers. Participants completed socio-demographic and psychological indices.

Each of the harmonized databases is already being used as a basis for scientific publications in the field of gerontology which have been published in Israel and abroad. The first three databases contain a wide range of epidemiological data, whereas the other two databases deal with various aspects of emotional adjustment.
