This paper in Archives of Gerontology and Geriatrics has just come out, written by me, Ann Bowling and Matthew Hankins at Southampton, Gill Windle at Bangor and Claudio Bilotta in Milan. In this we set out a reduced 13-question quality of life scale, reducing Prof Bowling’s OPQOL scale further based on the principle of asking older people themselves what really matters to them, rather than imposing some psychometric theory from the ivory tower. From a statistical point of view, it brought me into contact with Mokken scale analysis for ordinal data, for which I remain very grateful to Matthew. I picked up a copy of the slim but informative “Ordinal Item Response Theory” by van Schuur, which has already proven to be a useful addition to my groaning bookshelves.
