BACKGROUND Overall results from Cognitive Remediation (CR) indicate robust and long-lasting effects with medium effect size on global cognition and functioning, and a small ES on symptoms present at post-treatment but not at follow-up. However, results are not the same in all CR therapies and in some cases no efficacy results are achieved. AIMS To develop(More)
Family impact (or family burden) is a concept born in the field of mental health that has successfully been exported to the ambit of intellectual disability (ID). However, differences in family impact associated with severe mental health disorders (schizophrenia), to ID or to mental health problems in ID should be expected. Seventy-two adults with(More)
Back-focal-plane interferometry is used to measure displacements of optically trapped samples with very high spatial and temporal resolution. However, the technique is closely related to a method that measures the rate of change in light momentum. It has long been known that displacements of the interference pattern at the back focal plane may be used to(More)
A major problem with holographic optical tweezers (HOTs) is their incompatibility with laser-based position detection methods, such as back-focal-plane interferometry (BFPI). The alternatives generally used with HOTs, like high-speed video tracking, do not offer the same spatial and temporal bandwidths. This has limited the use of this technique in precise(More)
Optical trapping has become an optimal choice for biological research at the microscale due to its non-invasive performance and accessibility for quantitative studies, especially on the forces involved in biological processes. However, reliable force measurements depend on the calibration of the optical traps, which is different for each experiment and(More)
BACKGROUND Research on insight in patients with mood disorders has grown in recent years. Several instruments to assess insight have been used, but most of them have been specifically designed for psychosis and may not appear relevant to mood disorders. The aim of the present study is to develop a short, multidimensional, reliable and valid scale to measure(More)
The ability to measure forces in the range of 0.1-100 pN is a key feature of optical tweezers used for biophysical and cell biological studies. Analysis of the interactions between biomolecules and the forces that biomolecular motors generate at the single-molecule level has provided valuable insights in the molecular mechanisms that govern key cellular(More)
