A theory of change for one-on-one peer support for older adolescents and young adults.

Peer support has become increasingly available as a formal mental health service. However, high quality research and implementation of peer support has been hampered over the years by the lack of theory that clarifies peer support roles and explains exactly how these roles foster positive outcomes for peer support users. Observers have noted that theory is particularly sparse in regard to peer support for older adolescents and young adults, and they have called for theory that not only clarifies roles and mechanisms of impact, but also identifies how peer support for young people might differ from peer support for older adults This qualitative study brought young people with experience providing and using peer support together in small group discussions focused on understanding the activities and outcomes of peer support.

Visual feedback alters force control and functional activity in the visuomotor network after stroke.

Modulating visual feedback may be a viable option to improve motor function after stroke, but the neurophysiological basis for this improvement is not clear. Visual gain can be manipulated by increasing or decreasing the spatial amplitude of an error signal. Here, we combined a unilateral visually guided grip force task with functional MRI to understand how changes in the gain of visual feedback alter brain activity in the chronic phase after stroke.
