A study examined the readership of state cooperative extension offices' home learning programs--nine series of booklets of information about pregnancy, infant development, and parenting, mailed to parents in ten states to coincide with pregnancy stage and baby's age in months. The reading level of the series varied from sixth to eighth-grade level. Data were gathered using an evaluation questionnaire sent to parents as they completed the booklet series. Of the more than 51,000 parents estimated to have received the series during the study year, 2,263 returned their questionnaires. Results indicated that while respondent characteristics varied from state to state, most were 25 years old or older, white, married with some post high school education. Fifty percent lived in urban areas, and 60% were first time parents. Results also indicated that all booklet series were well read, with 84% of the respondents reporting having read all articles in all issues, and 74% reporting that someone other than themselves--usually the spouse and/or the baby's grandparents--also read the booklets. Eighty-five percent rated the writing style of the booklets as "just right," and most reported that all the major subjects included were "somewhat" or "very" helpful. Results suggest that the booklets achieved their intended purpose, and that "age-paced" home learning programs serve a useful purpose. (HTH)
