Related to this question regarding the use of readability formulas...  I'm
interested in what all of you think about composing a list of low-literacy
materials in cases where the list creator is not evaluating the readability
of each material.  In cases where the authors/developers of materials are
asked to submit "easy-to-read" materials to the list, what evidence should
the developer be asked to provide to show that a material is a "low-literacy
material".  

In some cases, materials can be deemed "low-literacy" by authors but have
never been pilot tested with poor readers or evaluated using a readability
formula.  Perhaps the material is "written by someone with experience in
writing 'low-literacy' materials."  Should these materials be included?

I'm curious as to what suggestions you would have for objective inclusion
criteria.
Use of the SAM evaluation tool, pilot testing with persons know to read at
the 6th grade level, tested with a readability formula...

		Point well taken. But I still use readability formulas
pretty regularly, and 
		I try to get clients not to rely exclusively on grade level
estimates. 
		Pointing out that their materials are written at a graduate
school reading 
		level, or that their document averages 30 words per sentence
does get their 
		attention. 

		There is evidence that word frequency is a reasonable
estimate of word 
		difficulty. Words that do not appear very often in print are
usually harder 
		to read and understand than words that appear frequently.
[Breland, H.M. 
		(1996) Word frequency and word difficulty: A comparison of
counts in four 
		corpora. Psychological Science, 7, 96-99]

		Depending on the words used, text can be incomprehensible at
any grade level. 
		I think it's a mistake to conclude that 6th graders can
always understand 
		something written at a 6th grade reading level. They may if
the writer really 
		knows the audience; if not, then  readers won't understand. 

		We also need to be aware of document length and information
overload.  For 
		example, the new HIPAA (Health Insurance Portability and
Accountability Act) 
		will transform the way health care facilities use patient
information, so 
		hospitals have to inform patients about their privacy
rights. A sample HIPAA 
		consent form from the American Hospital Association
(developed by a law firm) 
		was 3,600 words long--180 sentences at a 2nd year college
reading level. This 
		document may be completely incomprehensible for sick (and
elderly) patients 
		under physical, psychological, and emotional stress.
Re-writing it to a lower 
		grade level may not help at all if there is still more
information than the 
		patient can process. [Hochhauser, M. (2001) How you can
comply with 
		HIPAA--and help your patients understand their privacy
rights. Patient Care 
		Management, 16(12), 1; 3-4] Of course readability formulas
were developed 
		well before concepts of information processing and
information overload were 
		discovered. 

		When I do a reability analysis I always include all the
text, rather than 
		just a sample of a few hundred words, since total number of
words is an 
		important measure. Most people read 200-300 words per
minute, so a 3,600 word 
		HIPAA document may take 15 - 20 minutes to read. Is that
feasible during a 
		hospital admission process? 

		Common, everyday, concrete words are more likely to be
understood than rare, 
		abstract words. Most of the readability researchers
recognized this point, 
		and emphasized the importance of using words that readers
already understand. 
		Jargon, even if it's a one-syllable word, may be
incomprehensible to people 
		who aren't in the same field.
