Stimulant medications: a trade-off? The lived experience of adolescents with ADHD.

PURPOSE: The purpose of this study was to gain information and insight about prescription stimulant medication use among children and adolescents with attention deficit-hyperactivity disorder (ADHD) across developmental stages. DESIGN AND METHODS: Investigators conducted semistructured qualitative interviews with 15 college students with ADHD. Follow-up interviews confirmed and validated information obtained during initial interviews. RESULTS: Qualitative data analysis resulted in three global categories related to the use of prescription stimulant medication from childhood to late adolescence: (a) the early years, (b) "the trade-off," and (c) stimulant medications in college. PRACTICE IMPLICATIONS: Increased education about prescription stimulant medications and closer management is needed to reduce side effects and minimize the risks of misuse.

Effect of methylphenidate on time perception in children with attention-deficit/hyperactivity disorder.

The effects of methylphenidate (MPH) on performance of a time-production task were studied in 17 children with attention-deficit/hyperactivity disorder who participated in 1 test session on and 1 off MPH. Participants held a response lever down for at least 10 but no longer than 14 s. Administration of MPH had no effect on the number of correct responses or on the mean duration of lever holds. MPH administration significantly decreased timing response variability, increased holds of 10- to 11-s duration, and decreased lever holds of extremely short durations. These results indicate that administration of MPH resulted in more precise timing performance without changing the mean duration of lever holds, suggesting an enhancement in working memory.

Time perception differences in children with and without ADHD.

INTRODUCTION: The purpose of this study was to compare time perception in children with and without attention deficit hyperactivity disorder (ADHD) with use of a time reproduction task. METHODS: The sample consisted of 60 children (30 with ADHD and 30 without ADHD) ranging in age from 9 to 12 years. Children were asked to watch a light, verbally estimate how long the light was illuminated, and hold a lever in a depressed position for the same amount of time they thought the light was on. Each child participated in 16 trials of 3, 6, 12, or 24 seconds for a total of 64 trials. RESULTS: Children with ADHD had significantly greater absolute discrepancy scores on the time reproduction task (F(1,58) = 10.878; P <.01) than did children in the control group. In addition, children with ADHD had greater increases in absolute discrepancy scores across time intervals (F(3,174) = 82.08; P <.01). DISCUSSION: Poor time perception affects the performance of social skills and other adaptive behaviors such as health consciousness and concerns for safety. The findings of this study indicate that children with ADHD have impaired time perception compared with children who do not have ADHD.

The relationship between behavioral inhibition and time perception in children.

PURPOSE: To test one component of Barkley's (1997) model of executive functions by examining the relationship between behavioral inhibition and time perception in children. METHOD: Correlation analysis was used to determine the relationships between measures of behavioral inhibition and time perception for the entire sample, and for boys (n = 34) and girls (n = 26) separately. FINDINGS: For both parent and child measures, behavioral inhibition and time perception scores were correlated for the total group and for girls. Child measure of behavioral inhibition and time perception were not correlated for boys. CONCLUSIONS: The findings of this study support Barkley's theory and indicate a relationship between poor behavioral inhibition and poor time perception in children.
