Protocol for a Randomized Hybrid Type 2 Trial on the Implementation of Group Problem Management Plus (PM+) for Venezuelan Women Refugees and Migrants in Colombia

Background: Task-sharing interventions have shown to be feasible and effective in reducing symptoms of psychological distress. Research is currently needed on how task-shared interventions can be sustained with less-intensive technical support from mental health providers, often available in controlled research trials. This study protocol aims to evaluate the effectiveness of Group Problem Management Plus (PM+) and the adoption, fidelity and maintenance of the intervention when delivered and supervised by nonspecialists. Methods: This study utilises a type-2 hybrid implementation design to compare participant-level outcomes when the intervention is delivered by nonspecialists who receive technical support by psychologists versus nonspecialised support by lay providers. Venezuelan and Colombian women in Barranquilla, Colombia reporting moderate levels of distress will be randomised (N= 128 total) to receive PM+ delivered by nonspecialists who receive training and supervision by a: 1) psychologist; or 2) nonspecialist. Psychosocial wellbeing, general distress and functioning will be measured at baseline, 1-week and 3-months post intervention. A process evaluation will be guided by the RE-AIM framework. Discussion: Results will determine if Group PM+ is feasible and effective to implement in lower resource contexts with less-intensive specialised support. This research especially has implications for humanitarian settings with a limited number of mental health providers. Trials Registry: ClinicalTrials.gov identifier: NCT0547735

Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H??????? and H???ZZ*???4??? Decay Channels at s\sqrt{s}=8??????TeV with the ATLAS Detector

Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3~fb$^{-1}$ of $pp$ collisions produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = 8$ TeV and recorded by the ATLAS detector. Cross sections are obtained from measured $H \rightarrow \gamma \gamma$ and $H \rightarrow ZZ ^{*}\rightarrow 4\ell$ event yields, which are combined accounting for detector efficiencies, fiducial acceptances and branching fractions. Differential cross sections are reported as a function of Higgs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transverse momentum of the leading jet. The total production cross section is determined to be $\sigma_{pp \to H} = 33.0 \pm 5.3 \, ({\rm stat}) \pm 1.6 \, ({\rm sys}) \mathrm{pb}$. The measurements are compared to state-of-the-art predictions.Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3  fb-1 of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of s=8  TeV and recorded by the ATLAS detector.
