The effect of active support training on engagement, opportunities for choice, challenging behaviour and support needs

Background: The aim of this study was to evaluate active support (AS) training and to investigate changes to perceived engagement in domestic tasks, opportunities for choice, frequency of challenging behaviour, and level of support needs.

Method: Participants were 12 adults with ID aged 27–57 years (M = 37 years) residing in three group homes, and their support workers. The support workers completed assessments on three occasions (at baseline, post-training, and at follow-up).

Results: Residents' engagement in domestic tasks increased over time, and overall choice increased, although perceived choice in two life domains initially increased, but decreased to baseline levels at follow-up. Residents exhibited an overall decrease in anxiety, self-absorbed behaviour, disruptive behaviour, and problem behaviour in general. There was also an overall decrease in perceived support needs for five activity domains, with no change for one domain.

Conclusions: The results contribute to a growing body of evidence demonstrating favourable outcomes of AS in terms of engagement and challenging behaviour in people with ID. Surprising results are presented for choice and perceived support needs, warranting further investigation.

Staff behaviour and resident engagement before and after active support training

Background Identifying the factors associated with greater increases in resident engagement has the potential to enhance the effectiveness of active support (AS).

Method Observational data from Stancliffe, Harman, Toogood, and McVilly's (2007) study of AS were analysed to evaluate amount of staff help, effectiveness of staff help, and staff use of praise.

Results Lag analyses showed that antecedent staff help was consistently followed by resident engagement at pre-test. This strong association did not increase significantly at post-test. Resident engagement was more likely to follow staff help than the other way around. There was an increase from pre-test to post-test in help and praise by staff. The higher absolute amount of praise was largely the result of the increase in staff help.

Conclusions The amount of staff help, its effectiveness, and use of praise by staff may each be important in increasing engagement. These factors should continue to be the focus of research attention and applied efforts to help ensure active support is consistently effective.

Why neutron guides may end up breaking down? Some results on the macroscopic behaviour of alkali-borosilicate glass support plates under neutron irradiation

In this paper we report on a first part of a study on the mechanisms leading to brittle fracture in neutron guides made of glass as structural element. Such devices are widely used to deliver thermal and cold neu tron beams to experimental lines in most large neutron research facilities. We present results on macroscopic properties of samples of guide glass substrates which are subjected to neutron irradiation at relatively large fluences. The results show a striking dependence of some of the macroscopic properties such as density, shape or surface curvature upon the specific chemical composition of a given glass. The relevance of the present findings for the installation of either replacement guides at the existing facilities or for the deployment of instruments for ongoing projects such as the European Spallation Source is briefly discussed.
