ABSTRACT
BACKGROUND: The prevalence of poor reading skills is particularly high among children from low socioeconomic backgrounds, but no longitudinal studies have been conducted so far in France to determine whether poor reading in a socioeconomically challenged population is persistent and warrants preventive action. DESIGN: One hundred and fifty-four children were divided into three groups according to their reading skills: poor, intermediate and typical readers. They were followed over a period of 2 years. Reading levels, spelling and comprehension were assessed by standardized measurement scales in order to determine reading outcome and predictive variables. RESULTS: The reading skills in each group progressed at similar rates, but the differences between the three groups remained relatively constant over the 2 years. The gap between good and poor readers actually increased for the poorest readers. Spelling scores followed a similar pattern and remained weak. Comprehension scores followed a different pattern. Most of the initially poor readers with low comprehension scores almost caught up and reached the level of the typical readers. The best predictive variables of reading and spelling outcome were phonological awareness, rapid naming and attention deficit. The strongest predictive variables for comprehension were IQ, lexical level and attention. CONCLUSIONS: Our results confirm the relative stability of reading measurement across time in poor readers from low socioeconomic backgrounds. Their behavior are similar to the classic dyslexic population. The predictive variables are different depending on whether reading or spelling or comprehension is considered. These results provide a clear agenda for preventive literacy action in children with low socioeconomic levels (SES): phonological decoding and oral language skills in early grades, and screening and treatment of attention disorders.

BACKGROUND: Reading impairment is the major learning disability in children. While research on illiteracy has mainly been conducted from a sociological perspective, research on dyslexia has typically been studied from a cognitive-linguistic perspective. Studies that jointly investigate sociological, behavioral and cognitive factors in predicting reading outcome are rare and limited to English-speaking populations. The goal of the present study was to screen second grade children with reading impairment in French urban elementary schools and to pin down the factors that explain the various facets of reading failure and success. METHODS: A total of 1062 children from 20 different schools in the city of Paris participated in the study. Different aspects of reading were assessed individually for children with a suspected impairment in reading acquisition. Subsequently, 131 poor readers and 50 typically developing readers were matched for sex, age, and school. For these children, medical, cognitive, behavioral and individual socioeconomic data were obtained. Group differences were examined and multiple regression analyses were conducted to examine how much variance in reading was explained by the various variables. RESULTS: The prevalence of poor reading skills in grade 2 was highly influenced by neighborhood socioeconomic status (SES) (ranging from 3.3% in high SES to 20.5% in low SES areas). Among the SES variables, employment of the father was a significant predictor of poor reading. Among the cognitive variables, phonological awareness and rapid naming were the most significant factors, much more than verbal or nonverbal intelligence. Among the behavioral variables, attention was an important factor but not externalized symptoms. Multiple regression analyses showed that reading outcome was best predicted by phonological awareness skills and attention deficits. CONCLUSION: The majority of children with reading disability come from low SES areas. As in the English literature, the most robust predictor for reading impairment is phonological awareness, even when SES is taken into account. In addition, attention deficits seemed to aggravate reading impairments for children with weak phonological awareness skills. Successful early prevention should focus on reinforcing phonological awareness, recoding and attention skills.
