Effects of treatment on linguistic and social skills in toddlers with delayed language development.

This study investigated the effects of early language intervention on various linguistic and social skills of late-talking toddlers. The 21 children who participated in the investigation were randomly assigned to an experimental group (n = 11) or a control (delayed-treatment) group (n = 10). The experimental group participated in a 12-week clinician-implemented language intervention program. Groups were compared at pretest and posttest on five linguistic variables: Mean Length of Utterance, Total Number of Words, Number of Different Words, Lexical Repertoire, and Percentage of Intelligible Utterances, as well as on Socialization and Parental Stress. Significant group differences were found for each of the variables, indicating facilitative effects of the treatment. Notably, increases were observed in areas that were not specifically targeted by the intervention. Implications of these results are discussed with respect to considerations regarding clinical management decisions for toddlers with delayed language development.

A longitudinal study predicting patterns of cigarette smoking in late childhood.

Early initiation of cigarette smoking so strongly predicts future smoking that several investigators have advocated delaying the age of initiation as a prevention strategy. To complement retrospective studies of early initiation, this study assessed prospectively patterns of smoking behavior in a sample of 401 children who were surveyed in the fifth, sixth, and seventh grades. The principal findings were (1) modeling of smoking by parents and friends is sufficient to influence children to initiate smoking, particularly when children also have low behavioral self-control, and (2) when modeling occurs in combination with poor adjustment to school, low parental monitoring, easy access to cigarettes, and other risk attributes, early initiators are significantly more likely to continue smoking. The results suggest that delaying initiation of smoking without also modifying child attributes and socialization factors that predict early initiation and persistent smoking is unlikely to reduce the proportion of children who become habitual smokers.

The influence of peer models on the play scripts of children with specific language impairment.

This investigation included two phases of inquiry that examined the effects of peer modeling upon the play scripts of children with specific language impairment (SLI). The first study employed a pretest-posttest control group design involving two groups of children with SLI (10 who participated in the experimental treatment and 10 controls) and a group of peer models (10 children with normal language development). The treatment involved dyadic play sessions in which children with SLI were paired with a normal language peer model. Significant differences were found between the play script reports of the experimental (SLI-E) and control groups (SLI-C) of children with specific language impairment. The second study, utilizing single-case methodology, involved 6 children with SLI who participated in the control group of Study 1, plus 2 peer models. Play dyads consisted of either two children with SLI or one child with SLI and a normal language peer. Results of this study provided support for the contention that play interactions with normal language peers facilitates increases in the play-script reports of children with SLI.

Initiation of cigarette smoking among children with and without learning disabilities.

The goals of this study were to determine if: (1) children with learning disabilities should be included in school-based smoking prevention programs and (2) existing prevention curricula are appropriate for children with learning disabilities. Initiation of cigarette smoking and several correlates of smoking, including personal attribute, peer influence, and parent influence variables, were measured in a sample of 1470 3rd and 5th grade children. The rates of smoking initiation were 17% and 15% for children with and without learning disabilities, respectively. In addition, several of the known correlates of smoking among youth, including low self-control, negative orientation toward school, and peer smoking, were also significantly associated with smoking by children with learning disabilities. Children with learning disabilities are as much in need of smoking prevention programs as children without learning disabilities. Although current smoking prevention curricula address issues relevant to children with learning disabilities, additional research is needed to identify the special needs of these children and to determine the type of smoking prevention program most likely to be effective with them.

Nursing resource management: analyzing the relationship between costs and quality in staffing decisions.

A statistical model can be used to quantify the relationship between cost and quality in nurse staffing decisions and to demonstrate that high-quality health care is not necessarily synonymous with high-cost health care.
