From the selected 81 survey instruments, we identified 326 potentially useful items.
Furthermore, Table 1 of our paper (Krauth et al. 2013) lists the criteria found in most instruments we identified.
From 32 of these instruments, we identified 1,860 potential items, which included Legacy HAQ-DI and PF-10 items.
However, by systematically reviewing existing instruments, we identified that a broadly applicable instrument that accurately measures and monitors mobility of older adults across the spectrum of health does not exist [ 3].
By focussing on differences taken over comparable survey instruments, we identify effects that can be meaningfully interpreted as valid for a consistent migrant subgroup, even if this "migrant subgroup" is not fully representative of all Australian immigrants.
The greatest opportunities for the BelRAI-instrument we identified were a timely and systematic detection of (early) problems (1), the early development of a care plan (2) and its contribution to continuity of care (transfer of data) (3).
For the successful implementation as a planning instrument we identify the legally required regulation in the planning process and the existence of reliable data as major challenges.
Through a natural experiment enabled by an instrument variable, we identify two forms of social media information that act as signals of borrowers' creditworthiness: (1) borrowers' choice to self-disclose their social media account to the P2P lending site, and (2) borrowers' social media behavior, such as their social network scope and social media engagement.
This is an advantage over all published instruments for NPs that we identified.
We identified instruments that addressed internet use [ 11], internet use for health purposes [ 12, 13], computer and internet anxiety [ 14], computer and internet abilities [ 15- 18], attitudes and beliefs about the internet [ 14, 19- 21], risk perception [ 22- 28], internet security and privacy [ 6], health literacy [ 7, 29- 32], motivation [ 33, 34], and media literacy [ 7].
Consequently, we identified two instruments appropriate for the primary care practice setting that suited our purpose.
