Individual Placement and Support and Participatory Workplace Intervention on the Work Participation of People with Disabilities: A Randomised Controlled Trial.

PURPOSE: This study assessed the effectiveness of Individual Placement and Support (IPS), Participatory Workplace Intervention (PWI), and IPS + PWI on work participation and health of people with work disabilities. METHODS: A randomised controlled 2 × 2 factorial trial with 120 clients and an 18-month follow-up was performed. Differences between IPS and no-IPS and between PWI and no-PWI were assessed using log-rank tests and Cox proportional hazards models. RESULTS: In the IPS group, restricted mean survival time (RMST) for sustainable paid employment was 352 days, compared to 394 in the no-IPS group (HR = 1.47, 95% CI = 0.81-2.63). In the PWI group the RMST was 378 days, compared to 367 in the no-PWI group (HR = 0.89, 95% CI = 0.48-1.64). For the secondary outcome 'starting any paid employment, a trial placement, or education' RMST was significantly lower for the IPS group (222 days) than for the no-IPS group (335 days; HR = 1.85, 95% CI = 1.01-3.42). Mental health was significantly lower (worse) in the PWI group (difference -4.07, 95% CI = -7.93 to -0.22) than in the no-PWI group. For all other secondary outcomes, no statistically significant differences were found. CONCLUSION: No statistically significant differences were observed in the duration until starting sustainable employment between IPS and no-IPS, and between PWI and no-PWI. The duration until starting any paid employment, a trial placement, or education was shorter in the IPS group than in the no-IPS group, but further research should explore whether this also increases sustainable employment in the longer term.

Process Evaluation of Individual Placement and Support and Participatory Workplace Intervention to Increase the Sustainable Work Participation of People with Work Disabilities.

PURPOSE: This study is a process evaluation of the use of Individual Placement and Support (IPS) and Participatory Workplace Intervention (PWI) to increase the work participation of people with work disabilities. We ran the evaluation alongside a randomized controlled trial (RCT), to investigate whether and to what extent IPS and PWI were executed according to protocol. METHODS: The study population consisted of clients with work disabilities, and their job coaches who were employed by the municipality of a large city in the Netherlands. Data were collected between September 2019 and November 2022 using registration forms, accompanied by researchers' notes and logbooks. RESULTS: For IPS the dose delivered was reasonable and the IPS fidelity measurement score was fair. The job search focused on paid work for almost all clients and was based on their wishes as indicated in the protocol, but integration of employment services with (health) care was often lacking. A minority of the clients who were assigned to PWI received the intervention, often because the client did not start work within the follow-up period and a workplace was a requirement to apply the intervention. CONCLUSION: The results of this study show that IPS was executed reasonably and with a fair fidelity, which indicated implementation was sufficient to find an effect on work participation in the RCT. PWI was barely realized in practice and no conclusions regarding the fidelity could be drawn. We therefore conclude that we cannot expect PWI to have any effect on work participation in the RCT.

Evaluation of sample spin-polarization from spin-polarized scanning tunneling spectroscopy experiments.

Spin-polarized scanning tunneling microscopy has produced a great amount of images presenting magnetic contrast between different magnetic domains with an unsurpassed spatial resolution but getting values like the surface polarization has proven to be a difficult task. We will discuss in detail how to extract this information for the case of manganese layers grown on Fe(001) whiskers. Mn layers adopt a body-centered-tetragonal (bct) structure when they are grown on the Fe(001) surface at room temperature. The Mn layers show an antiferromagnetic coupling between the layers. Comparing our spin-polarized scanning tunneling spectra measured with Fe-coated W tips with spin-resolved band structure calculations, we are able to find the value of the sample surface polarization. Also discussed is a method to change the tip magnetization. Finally, the magnetic structure around a screw dislocation on the surface is reviewed.

Semiautomatic bridge for high-precision dc resistance measurements on pure metals at low temperatures.

A self-balancing bridge system with a dc current comparator and a superconducting flux-gated galvanometer is described. The bridge is capable of measuring small resistances (10(-4)-10(-7) Omega) at liquid helium temperatures with an accuracy of 1 ppm.

Amblyopia & Strabismus Questionnaire: design and initial validation.

Literature on the benefits of screening and treatment of amblyopia emphasizes the costs of insufficiently treated amblyopic patients who lose their better eye. However, patients with insufficiently treated amblyopia and strabismus who do not lose their better eye only experience a slight decrease in their quality of life, and such patients occur more frequently. We designed and validated a questionnaire for amblyopia and strabismus in order to assess the decrease in quality of life of such patients. Complaints were collected from outpatients and reduced to five domains, pertaining to distance estimation, visual disorientation, problems with social contacts and cosmetic problems, diplopia, and fear of losing the better eye. For these domains 26 questions were formulated that constitute the Amblyopia & Strabismus Questionnaire (A&SQ). The A&SQ, the National Eye Institute Visual Function Questionnaire-25 (VFQ-25) and the Short Form-12 Health Survey (SF-12) were presented to 53 healthy controls, 68 outpatients and a cohort of 174 outpatients born between 1962 and 1972 and treated between 1968 and 1974 for amblyopia and strabismus. The quality of life was best in healthy controls and worst in current outpatients, not only on the SF-12 and the VFQ-25 but also on the A&SQ, demonstrating an acceptable construct validity of the A&SQ. The decrease in the quality of life as measured by the A&SQ was most outspoken in our outpatient group of amblyopia and strabismus patients, less in the cohort that had been treated 30 years previously and least in the healthy controls, demonstrating an acceptable discriminatory validity of the A&SQ.
