AbstractExperimental tests of the association between relationship functioning and physical health are limited. Although associations are hypothesized to be partially mediated through improved psychological functioning, tests are mostly limited to lab‐based studies. The present study evaluated relational and psychological mediators of change in perceived health in a sample of 742 low‐income couples (1,484 individuals) who participated in a randomized controlled trial of two online relationship education programs and a waitlist control group. Results partially supported the Strengths and Strains Model of Relationships and Physical Health. Relationship functioning and some psychological functioning were mediators of change in perceived health. Future research is needed to understand how relationship functioning improved perceived health through mediators other than psychological functioning tested here.

ObjectiveTo assess program completion of the online OurRelationship program with varying levels of paraprofessional support in an effort to further examine the role of coach support in self‐help couple interventions.BackgroundAlthough the OurRelationship program for distressed couples has been found to statistically improve relationship and individual functioning, the program's provision of paraprofessional coach support limits its dissemination and implementation.MethodUsing an interrupted time series design, we compared completion rates of those who enrolled in a trial of OurRelationship with no coach support (n = 529 couples) to completion rates of a previous trial of OurRelationship in which couples were randomized to receive either one (n = 179 couples) or four (n = 177 couples) calls with a coach.ResultsIndividuals were statistically less likely to complete the OurRelationship program when they were not provided a coach than they were when provided with either one or four coach calls. Analyses of moderators of completion rates revealed that a coach was generally equally helpful across demographic factors and measures of baseline relationship and individual functioning; however, coaching was especially helpful for Hispanic individuals and those without elevated depressive symptoms at baseline.ConclusionsEven a single call with a coach yields higher completion of an online program for relationship distress.ImplicationsThe findings highlight the growing need for tests of alternate types of program support, such as automated support, in an effort to reduce program costs and increase potential for dissemination without negatively affecting program completion rates.

We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search, ephemerides overlapping the run period were obtained for all pulsars using radio and X-ray observations. We demonstrate an updated search method that allows for small uncertainties in the pulsar phase parameters to be included in the search. We report no signal detection from any of the targets and therefore interpret our results as upper limits on the gravitational wave signal strength. The most interesting limits are those for young pulsars. We present updated limits on gravitational radiation from the Crab pulsar, where the measured limit is now a factor of 7 below the spin-down limit. This limits the power radiated via gravitational waves to be less than similar to 2% of the available spin-down power. For the X-ray pulsar J0537-6910 we reach the spin-down limit under the assumption that any gravitational wave signal from it stays phase locked to the X-ray pulses over timing glitches, and for pulsars J1913+1011 and J1952+3252 we are only a factor of a few above the spin-down limit. Of the recycled millisecond pulsars, several of themeasured upper limits are only about an order of magnitude above their spin-down limits. For these our best (lowest) upper limit on gravitational wave amplitude is 2.3 x 10(-26) for J1603-7202 and our best (lowest) limit on the inferred pulsar ellipticity is 7.0 x 10(-8) for J2124-3358. ; Australian Research Council ; Council of Scientific and Industrial Research of India ; Istituto Nazionale di Fisica Nucleare of Italy ; Spanish Ministerio de Educacion y Ciencia ; Conselleria d'Economia Hisenda i Innovacio of the Govern de les Illes Balears ; Netherlands Organisation for Scientific Research ; Royal Society ; Scottish Funding Council ; Polish Ministry of Science and Higher Education ; Foundation for Polish Science ; Scottish Universities Physics Alliance ; National Aeronautics and Space Administration ; Carnegie Trust ; Leverhulme Trust ; David and Lucile Packard Foundation ; Research Corporation ; Alfred P.
