Journal article (peer-reviewed)abstract
- To describe the development of words and sentences in Swedish children 16-28 months old, 900 parental reports on 336 children were analyzed. Subjects were randomly selected from the national birth register, and there was a response rate of 88%. The assessments were made using the Swedish Early Communicative Development Inventory-words and sentences (SECDI-w&s). Age-based norms for productive vocabulary, pragmatic skills, grammar skills, and maximum length of utterance (MaxLU) were determined. We describe the development of feedback morphemes, semantic categories, and single words and tasks. Correlation across measures was significant, and especially strong between vocabulary size and grammar skills. Optimized positive predictive values were high for 25 to 28 month predictions (71%-88%), and vocabulary scores were found to be of particular predictive importance. No significant gender differences were detected. The clinical relevance of the instrument is discussed.

- Spoken language in children with Down syndrome and in children in a normative group was compared. Growth trends, individual variation, sex differences, and performance on vocabulary, pragmatic, and grammar scales as well as MaxLU (maximum length of utterance) were explored. Subjects were 330 children with Down syndrome (age range: 1-5 years) and 336 children in a normative group (1;4-2; 4 years;months). The Swedish Early Communicative Development inventory-words and sentences (SECDI-w&s) was employed. Performance of children with Down syndrome at ages 3;0 and 4;0 was comparable with that of children in the normative group at ages 1,4 and 1;8 respectively. In comparison with children in the normative group of similar vocabulary size, children with Down syndrome lagged slightly on pragmatic and grammar scales. The early development proceeded in most cases with exponential or logistic growth. This stresses the great potential of early intervention.

Journal article (peer-reviewed)abstract
- An instrument designed to assess young children's communicative skills at 18 months is described. The instrument consists of a 103-item parental report checklist based on the Swedish version of the Communicative Development Inventories (SECDI). We present descriptive data from a study at the Swedish Community Health Care Centres, including parental reports of 1021 18-month-old children. The response rate was 88%. Performance at the 10th percentile consisted of 8 communicative gestures, 45 comprehended words, and 7 spoken words. The overall results indicate that the instrument is reliable and has validity approximating that of the SECDI. Furthermore, parents of the children with the poorest vocabulary indicated approval of the assessment procedure in interviews especially directed to this group.

A short-term follow-up of children with poor word production at the age of 18 months
- 2004
-
In: Acta Paediatrica. - 0803-5253 .- 1651-2227. ; 93:5, s. 702-706

Journal article (peer-reviewed)abstract
- Aim: (a) To study the stability of poor language development assessed by a new screening instrument based on parents' recognition of words their 18-mo-old children use; (b) to evaluate the predictability of the less-than-eight-words cut-off used by Child Health Centres (CHCs) in Sweden at the present 18-mo check-up--an assessment based on parents' recall of their children's vocabulary. Methods: All failures of the less-than-eight-words criterion, corresponding to about 10% of 1000 children from a community-based study, were followed up within half a year after the first assessment. The follow-up instrument was an extensive, internationally well-known and structured parent questionnaire, standardized for Swedish children. Results: Almost half of the followed-ups performed below the 10th percentile and more than two-thirds were found below the 20th percentile. Thus, after a few months about one-third of the children had caught up to a fairly normal level of performance. Two of the children who had recovered performed above median. More relaxed cut-off criteria were applied ad hoc , reducing the proportion of children with a fast recovery.
