| Abstract: | Parents used self-instructional booklets to decrease their children's (age4-8) whining. In each of 9 families, a multiple-baseline design across three problems, whining and two other was used. Parent data indicate mean improvement of 26% of the maximum possible from baseline means, with 8 of 9 children showing improvement. All parent final consumer ratings were positive. All interobserver reliabilities exceeded 80% agreement weighted for occurrence and nonoccurrence. Correlations for two sets of data between frequencies of whining estimated by parents twice an hour and percent of intervals recorded for whining from observer interval data for the hour produced median correlations of .62 and .51. Percent agreement between observer and parent data, both using interval recording at the same time, produced a median coefficient of agreement weighted for occurrence and non-occurrence of 59%. Results suggest that parents using self-instructional materials alone could reduce children's whining from levels originally considered excessive to levels parents considered acceptable. |
