The SSM is applicable to people with superannuation age, however, the variety of scores in (at least) one domain, namely that of Day-time activities, is very limited: normally these people are not employed and do not receive an education. Therefore, in this domain, they can score a 2 at the most. This limited variety in scores in the domain of Day-time activities has to be taken into account when setting goals for treatment and in expectations concerning the development of the elderly. Moreover, it should be prevented that an older person scores just a 1 in this domain.
With additional domains, specially developed for people above superannuation age, the SSM will be better applicable in practice and will be more relevant to professionals, policymakers and researchers who work within the field of the elderly health care. However, the development of new, additional domains is a structured and time consuming process. The determination of a domain name and the corresponding score-criteria which have a meaning for a broad group of users, requires a systematically and theoretically founded approach. It is expected that these additional domains will be developed in the course of 2013.
At the moment, additional domains are in the making in order to determine the level of self-sufficiency in the care of an adult for one or more children. Once realised, these domains can be used in addition to the current SSM. The development of these domains will be finished in the first half of 2013 and will be presented on this website. So keep an eye on this website!
We advise you to integrate the SSM and its scores into the registers and programs which are already in use within your institute or organisation, since its usefulness is among others dependent on the ease of the entering the input of the assessment in the database. The more actions are necessary to enter the assessment, the less user-friendly the SSM will be. This will influence (on the long term) the completeness and the reliability of the SSM scores. For users and other persons who are interested, and who have not yet integrated the SSM into their computer information system, the Public Health Service of Amsterdam (GGD Amsterdam) has developed an data-entry programme in Microsoft Access. If you have Microsoft Access (2003 or higher) at your disposal and you would like to make use of the entry programme, or whenever you have questions or would like to get advise about integrating the SSM into your registration system, please contact us via zrm@rontmc.nl.
No, you can not adjust the content of the SSM. The determination of domain names and the corresponding score-criteria which have a meaning for a broad group of users, requires a systematically and scientifically founded approach. All aspects (concerning the content) of the SSM are chosen accurately and add to the reliability and usefulness of the instrument. The omission of domains, the addition of domains or changes made to the (content of) the domains decrease the construct validity of the instrument and with that, the valid and reliable scores of the level of self-sufficiency. In addition, the main goals of the SSM are to promote the use of one language within the public care sector and to provide one standard in measuring results. We would like to prevent the circulation of different versions of the SSM as much as possible. Substantial changes made to the SSM would make the achievement of these goals impossible.
There is an article published at the TSG (Tijdschrift voor Gezondheidswetenschappen).* In this article, the inter-assessor reliability is in discussion among others. At the moment, there are two articles submitted for publication at scientific magazines. These two articles deal with the validity of the SSM and the possibilities to use the SSM as a Decision Support Tool (DST).  These articles are still in the review phase. Inquire via zrm@rontmc.nl about the current state of affairs.
