PARENT EDUCATION PROJECT III: INCREASING AFFECTION AND RESPONSIVITY IN DEVELOPMENTALLY HANDICAPPED MOTHERS: COMPONENT ANALYSIS,GENERALIZATION, AND EFFECTS ON CHILD LANGUAGE

We evaluated the effects of a parent training program consisting of verbal instruction, modeling, and feedback on the affection and responsivity of 3 developmentally handicapped mothers towards their children. The results indicated the following: First, the training package increased maternal physical affection, praise, and imitation of child vocalizations. These parenting skills increased to levels found in comparison groups of nonhandicapped mothers. Second, the training package was more effective than verbal instruction alone, the latter being the predominant method presently used by social service workers. Third, most maternal gains were maintained over a 3- to 18-month follow-up period, although one mother required a reinforced maintenance procedure. Fourth, instructing mothers to generalize served to increase the generalization of newly acquired skills from play times (the training context) to child-care tasks (e.g., diapering, feeding). Fifth, teaching the parents to imitate child vocalizations was related to gains in both the frequency and quality of verbal behavior of the two language delayed children as measured by standardized developmental tests and in vivo comparisons with age-matched children (who had nonhandicapped parents). These results show that behavioral instruction can improve important child-rearing skills of developmentally handicapped mothers, with corresponding benefits to their children.

School programs targeting stress management in children and adolescents: A meta-analysis

Introduction

This meta-analysis evaluates the effect of school programs targeting stress management or coping skills in school children.

Methods

Articles were selected through a systematic literature search. Only randomized controlled trials or quasi-experimental studies were included. The standardized mean differences (SMDs) between baseline and final measures were computed for experimental and control groups. Experimental groups were groups that either received an intervention of (a) relaxation training, (b) social problem solving, (c) social adjustment and emotional self-control, or (d) a combination of these interventions. If no baseline measurement was available, SMDs were calculated between final measures of the groups. The overall pooled effect size was calculated and the pooled effect sizes of improvement on stress, coping, (social) behavior, and self-efficacy by random effects meta-analysis. The dependence of the results on study characteristics (i.e. methodological quality and type of intervention) was evaluated using meta-regression analysis.

Results

Nineteen publications met the inclusion criteria of controlled trials for class programs, teaching coping skills or stress management. Overall effect size for the programs was − 1.51 [95% confidence interval (CI) − 2.29, − 0.73], indicating a positive effect. However, heterogeneity was significant (p < .001). Sensitivity analyses showed that study quality and type of intervention were sources of heterogeneity influencing the overall result (p values < .001). The heterogeneity in quality may be associated with methodological diversity and differences in outcome assessments, rather than variety in treatment effect. Effect was calculated per intervention type, and positive effects were found for stress symptoms with a pooled effect size of − 0.865 (95% CI: − 1.229, − 0.502) and for coping with a pooled effect size of − 3.493 (95% CI: − 6.711, − 0.275).

Conclusion

It is tentatively concluded that school programs targeting stress management or coping skills are effective in reducing stress symptoms and enhancing coping skills. Future research should use clear quality criteria and strive for less diversity in methodology and outcome assessment.     

Fatigue-related changes in the coordination of lifting and their effect on low back load

In this study, changes in movement coordination caused by fatigue that developed during repetitive lifting were examined. Five men performed 6 times a 5-min bout of lifting an 8-kg barbell at 15 lifts/min, using two lifting techniques; one minimized trunk rotation (squat lift), and the other minimized rotation in the knee joint (stoop lift). Kinematics and dynamics were studied by means of movement analysis and inverse dynamics, using a two-dimensional linked segment model. Within-subject variation over repetitive lifts of the time course of joint angles was smaller than between-subjects variation on the first analyzed lift. Relative timing between joint rotations did not change significantly across repetitive lifts, except between knee and hip in the squat lift. No change of the lumbosacral torque over repetitive lifts was found. The adaptability of the neural control appeared to be sufficient to accommodate the strong changes of the input-output characteristics of the muscles caused by fatigue so that an essentially constant performance of the movement act was maintained.
