Does written hepatitis C information meet the needs of injecting drug users? Professor Avril Taylor University of Paisley
Background to Study • Much information on HCV disseminated through written materials • In 2003 an awareness campaign used cards and posters • Knowledge evaluated pre and post campaign • No difference in knowledge • Other health literacy studies find discrepancy between literature and reading ability
Aims of the Study • To assess the reading levels of injecting drug users • To assess any association between reading level and risk behaviours • To assess the readability levels of written harm reduction leaflets on HCV • To assess sources of HCV knowledge • To determine IDUs preference for knowledge acquisition
Method • IDUs reading levels assessed using two validated tools (REALM and S-TOFHLA) • Interviewed using structured questionnaire - drug use, risk behaviours, knowledge of HCV, sources of knowledge, preferred format • Leaflets assessed using SMOG
REALM • Rapid Estimate of Adult literacy in Medicine • Assesses adults’ ability to read common medical words and lay terms for body parts and illnesses • 66-item word recognition test • One mark is given for each correctly pronounced word • The REALM score is the sum of correctly pronounced words
S-TOFHLA • Short Test of Functional Health Literacy in Adults • Respondents read out loud a number of sentences • Fill in a missing word from a provided list
S-TOFHLA Your doctor has sent you to have a____________ X-ray. a. Stomach b. Diabetes c. Stitches d. germsYou must have an_________ stomach when you come for_____.a. asthma a. is b. empty b. am c. incest c. if d. anaemiad. itThe x-ray will____________ from 1 to 3 __________ to do. a. take a. beds b. view b. brains c. talk c. hours d. look d. diets
Leaflet Assessment • 10 HCV leaflets distributed within GGHB and the recruitment centres were evaluated • The SMOG (simplified measure of gobbledygook) Readability Formula determines the readability level of written material • If someone has a reading age of, say, 12 years, they will understand 90-100% of material with a readability level of 12 • Most people will understand a readability level of about 10
Sample characteristics • 150 Glasgow IDUs • 69% male • Mean age = 32.02 years • Mean age left school = 14.87 years • Mean age first injected = 21.58 years • 60% no qualifications • 48 refused to take part

At the very least will need low literacy materials 12-14 years. Will struggle with most patient education materials >14 years. Will be able to read most patient education materials

Leaflet assessment • 10 leaflets ranged between equivalent reading age of 13-17 years • Mean readability level of 15-16 years • Those with reading age of 12-14 years or less (31%) would have problems understanding most of the leaflets • Some of those aged >14 years would have difficulty reading the leaflets

Conclusion • At least average reading age • Risk behaviours continue despite widespread knowledge of injecting transmission factors • At least one third would have difficulty reading current literature • Only 19% of those who had read a leaflet found it helpful; only 18% of those with reading age of >14 found it helpful • Only 23% had read a poster • Preferred source of information was verbal communication for all reading groups • 60% wanted to know more about HCV; 57% of >14 group • Implications for staff training
