A methodological workshop took place on May 28, 2017 in the Hebrew University, mount scopes, Jerusalem. The workshop provided information about updates, data analysis and recent findings, with a focus on the 6th Wave of SHARE (the 4th Wave in Israel). The program included 6 Lectures. To see the full lectures (in Hebrew), click on their title below.

Prof. Howard Litwin, from the latest publications based on data from SHARE:
The lecture presented three new studies of research staff members of the IGDC, which were based on data from SHARE. The first study, compared health status of older Israelis aged 65 and older with their European counterparts. All health status measures of Israeli respondents indicated a health status that was lower than the European average. The second study revealed that social networks contribute to levels of activity of people with mobility limitations, but do not contribute in this way to those without limitations. The last study showed that fear of falling down is a risk factor for falling mainly among people who do not have mobility limitations.

Noam Damri, Introduction to SHARE and wave 6 innovations
The lecture briefly presented The Survey of Health, Ageing and Retirement in Europe and Israel, and gave a wide overview of its goals, structure and scope. The collection of dried blood spots (DBS), the main innovation in wave 6, was presented. In addition, updates regarding the data structure were presented, as well as other technical and derived data sets designed to facilitate the use of SHARE data.

Ella Schwartz, Social networks data in Wave 6:
The lecture presented three new studies of research staff members of the IGDC, which were based on data from SHARE. The first study, compared health status of older Isrealis aged 65 and older  with respondents from 16 SHARE countries. All health status measures of Israeli respondents indicated a health status that was under the European average. The second study revealed that social network is particularly beneficial to those with multiple mobility limitations because it mitigates the negative association with activity. The last study showed that people who are worried about falling tend to fall more, but in cases of considerable mobility limitation, fear of falling may act as a protective buffer.

Hana Zoabi, Translation’s Issues and Cross-cultural adaptations of survey instruments:
Since Israeli society includes many social groups, there is a need to make the questionnaires clear to all of the interviewees. The lecture dealt with the adjustments and risk management which were made in the Israeli SHARE questionnaires, in order to adjust them to the different participating groups. The lecture presented the process of developing the survey questionnaires, the issues and challenges that arise during the work and how they are being overcome in SHARE.

Maayan Levinson, Mixed-effects moduels for longitudinal analysis:
The lecture was given in Hebrew and provided an introduction to mixed-effects models which are appropriate for longitudinal analysis. The subject was chosen in light of the release of wave 6 of SHARE which includes the 4th wave of data collected in Israel. The lecture attempted to avoid over-technical terminology and instead focused on the motivation of this method. It made use of SHARE data for demonstrating this methodology. Further use of mixed-effects models to analyze clustered data was also presented, defining countries as the clustering variable.

Ella Schwartz, Using weights in the analysis of population based surveys:
Population based surveys are a special type of survey, meant to represent the composition of a certain population. SHARE, for example, is meant to represent the population of people aged 50 and above in Europe and Israel. The lecture explained how data is collected for population based surveys and which type of analysis should be conducted so that the data will represent the population, while demonstrating these principles using SHARE data.
