简要总结
This study is being conducted to create a database for the Quotient® System iPad Test. Using community sampling, NCS Pearson will compile the results of this study to create a database against which the results of clinical Quotient tests may be compared to determine patient performance relative to the expected results for developmental age and gender.
详细描述
Study Design:
This study is being conducted at 4 clinical sites and consists of up to two study visits. All study participants will complete at least one study visit. A smaller cohort of participants will complete a second visit for the purpose of assessing test retest reliability across the study sample. Subjects will be recruited using the clinic's relevant patient population and IRB approved recruitment material. Interested volunteers will participate in an initial screening, which may be done by telephone or in person that will be conducted by the clinic's research staff. Upon preliminary confirmation that the subject meets all inclusion criteria and does not meet any exclusion criteria, an appointment will be scheduled for the first study visit.
At the first visit, the study will be explained in detail. Adults will be asked to provide written informed consent. Parents or guardians of individuals under the age of 18 years old will provide written informed consent on behalf of the minor. Individuals between the age of 7 and 18 years of age will also provide their written assent. All consents and assents will be obtained prior to any study procedure being performed. Following consent, a brief medical history, including current medications the subject is taking, will be obtained. Subjects will complete a standard self-assessment questionnaire, appropriate for age, to screen for presence of ADHD. Subjects will not be excluded from the study based on responses to the questionnaire but their results will be considered in the analysis of study data. All subjects will take the appropriate version; Child (ages 6 -12.11), Adolescent (ages 13 - 19.11), or Adult (ages 20 - 79.11) of the 15-minute Quotient® System iPad Test.
At this visit, a cohort of participants across 7 age groups will be asked to return the clinic for a second study visit. These participants will be asked, in consecutive order of enrollment, to return to the clinic for a second study visit. Study participants who complete visit one are not required to participate in the retest cohort group and may opt out of returning to the clinic for visit two. Once the required number of participants (350 - 400) have completed the second study visit, that portion of the study will be closed to further enrollment and no further subjects will be given the option to return for the retest visit (visit 2).
Retest Visit 2 will occur 7 - 14 days following study visit 1. Subjects will be assessed for changes in health status and current medications since the time of visit 1. Subjects will repeat the appropriate version (Child, Adolescent or Adult) of the 15-minute Quotient® System iPad Test.

研究组 & 干预措施
Quotient® System iPad Test
The Quotient® System iPad Test is a test specifically designed to provide clinicians with objective measures in ability to maintain seated stillness, sustained attention to a monotonous task and inhibiting incorrect impulsive responses. The attention task with motion analyses provides a number of objective measures for detailed assessment of the subject's movements and attentiveness.
