So I thought it worth emailing her myself, to ask whether any data were yet available. <br /><br /><br />She replied by return as follows:<br />'... Our study is still underway - we were fortunate enough to receive additional funding which has allowed us to continue to recruit and test a larger number of individuals. As a result we do not yet have data to release.... If you would like to be added to a mailing list, email k.white@alumni.ubc.ca. We will update you once we have published our results.'<br /><br /><br />I asked to join the mailing list, and was told that data collection from the increased sample is due to finish in aUtumn 2016. <br /><br /><br />The 'Research Initiatives' document dated Mar 2014 is available, along with other information docs and videos, at:<br />www.arrowsmithschool.org/arrowsmithprogram-background/research.html<br />Info about Dr Boyd's study as originally designed is on pp.7-9. It gives the numbers of participants in each group (two different versions) and some details of the measures and research plan. It does not answer the specific questions raised by Dorothy on 11 Sep.<br /><br /><br />Scanning this doc again, I found one other study (apart from Dr Boyd's) that included a control group, by W.J. Lancee (Toronto) 2003. The results are reported as favouring the Arrowsmith group. The groups are small, the data are complex and they involve varying participant selection for statistical analysis. Judging from Google Scholar, they have never been published in a peer-reviewed journal.<br /><br /><br />So the scientific case for benefit from the Arrowsmith program remains unclear. Dr Boyd's study, when finally completed, may cast more light.deevybeehttps://www.blogger.com/profile/15118040887173718391noreply@blogger.comtag:blogger.com,1999:blog-5841910768079015534.post-69523750528566287252015-09-11T04:37:03.795+01:002015-09-11T04:37:03.795+01:00Just to say that I didn't actually request det...Just to say that I didn't actually request details of the results, as the video I saw suggested the study was still ongoing. I asked two questions that should be easy to answer: (a) was the study registered and (b) who was funding it. Registration of clinical trials is pretty standard these days, and helps give confidence in the results as it means that the measures and hypotheses are prespecified.deevybeehttps://www.blogger.com/profile/15118040887173718391noreply@blogger.comtag:blogger.com,1999:blog-5841910768079015534.post-39221729974098666642015-09-06T15:17:30.905+01:002015-09-06T15:17:30.905+01:00Re Boyd, it may depend when Dorothy wrote the emai...Re Boyd, it may depend when Dorothy wrote the email. I live in Canada and the last 3-4 weeks would be prime vacation time for a prof, plus school is restarting in many places this week most everything from kindergarten to university so she might be getting kids of her own off to school, dealing with a new influx of students into her lab but it does not look all that good.jrkrideauhttps://www.blogger.com/profile/04869979887929067657noreply@blogger.comtag:blogger.com,1999:blog-5841910768079015534.post-30819271966732860662015-08-31T17:52:07.713+01:002015-08-31T17:52:07.713+01:00Several research studies are described on the Arro...Several research studies are described on the Arrowsmith website. All but one are uncontrolled i.e. they assess change in a single group of children pre and post an Arrowsmith programme. As Dorothy has said repeatedly, these are useless because it's not clear that any improvement over time is an effect of the programme. Just one study - Lara Boyd's, mentioned by Dorothy - has a control group. It was scheduled to collect data in Jan and June 2014, and Jan 2015. The fact that Dr Boyd didn't respond to a recent request for information suggests that the results might not have been favourable.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5841910768079015534.post-12788943500231510872015-08-30T11:47:41.448+01:002015-08-30T11:47:41.448+01:00I would have thought that those figures concerning...I would have thought that those figures concerning time spent on this program would be of considerable interest to the local schools and/or curriculum inspection authorities. This sounds more like a cult than a treatment (for anything).Nick Brownhttps://www.blogger.com/profile/18266307287741345798noreply@blogger.com
