At the conclusion of their study on home pregnancy test kits, Valinas and Perlman (1982) suggested that the instructions accompanying the kits be revised to make them easier to read. A study was undertaken to determine the readability of the printed instructions accompanying five home pregnancy test kits (Daisy II, Answer, Acu-Test, Predictor, and e.p.t.) available in the United States and the degree of correlation of selected formulas (Flesch Reading Ease, Revised Dale-Chall, Fog Index, SMOG Grading, and Fry Graph) in measuring levels of reading difficulty for short, nontext publications. The mean reading grade level for Daisy II, Answer, and Acu-Test was found to be grade 7. For e.p.t. the mean reading grade level was grade 8 and for Predictor the mean reading grade level was grade 9. The correlations between sets of readability scores ranged from r=.40 to r=1.00, indicating a moderate to high degree of similarity in measuring level of reading difficulty for short, nontext publications. These findings suggest that all five instruction leaflets are readable for adults who have at least a seventh grade reading skill, but that the use of unfamiliar technical terms and certain polysyllabic words could reduce the clarity of the directions for some readers.
