One hundred eighty-eight drug-abusing and conduct-disordered adolescents and their parents provided retrospective reports of the youths' frequency of alcohol and illicit drug use for each of the 6 months preceding their initial session in an outpatient treatment program. Youths' and parent reports of youths' drug and alcohol use for each month were similar.(More)
Previous research has examined the connoted hazard of various colour and signal words separately. The purpose of the present research was to examine the interaction of signal words and colours. Two separate experiments examined the influence of colour on perceptions of hazard and on compliance to printed warnings. In experiment 1, a sample of 30(More)
The authors conducted a Monte Carlo simulation of 8 statistical tests for comparing dependent zero-order correlations. In particular, they evaluated the Type I error rates and power of a number of test statistics for sample sizes (Ns) of 20, 50, 100, and 300 under 3 different population distributions (normal, uniform, and exponential). For the Type I error(More)
The purpose of the study was to assess differences in color preferences between the sexes. A sample of 193 retirees were asked to report their favorite colors. The pattern of frequencies for preferred color differed as a function of sex. Blue was chosen as the most preferred color by both sexes. Women preferred black and purple more than men did. Moreover,(More)
Signal words, such as DANGER, WARNING and CAUTION, are commonly used in sign and product label warnings for the purpose of conveying different levels of hazard. Previous research has focused on whether people's perceptions of connoted hazard are consistent with the levels suggested by design standards and guidelines. Most investigations have used college(More)
The Sport Interference Checklist (SIC) was developed in 141 athletes to assist in the concurrent assessment of cognitive and behavioral problems experienced by athletes in both training (Problems in Sports Training Scale, PSTS) and competition (Problems in Sports Competition Scale, PSCS). An additional scale (Desire for Sport Psychology Scale, DSPS) was(More)
OBJECTIVE Given the public health importance of suicide-related behaviors and the corresponding gap in the performance measurement literature, we sought to identify key candidate process indicators (quality of care measures) and structural measures (organizational resources and attributes) important for emergency department (ED) management of pediatric(More)
Reaction times (RTs) and net interference measures were obtained for 64 Stroop color-word stimuli from 8 common colors. Subjects were 64 college students, 32 of each sex. The incongruous stimulus was designated as either the ink interpretation different from the word or the word interpretation different from the ink. Consistently large variations within(More)
