|---|---|---|---|
| Primary | Dyadic Parent-Child Interaction Coding System (DPICS) - Behavior Counts | study endpoint- end of period II (between subjects trial) | Observations of parents and children as they interact with each other during a five minute homework task and during a 10 minute non-academic task. Interactions were recorded and later coded by trained observers. Observers counted number of parent and child behaviors. Average number of behaviors per group were computed. Three subjects dropped prior to completing this assessment and one participant completed the other endpoint measures but not the DPICS, which is why the total N for this outcome is 23 at study endpoint. At end of period II (study endpoint), the medication group (n=10) was compared to the placebo group (N=13). |
| Primary | Dyadic Parent-Child Interaction Coding System (DPICS) - Behavior Percentages | study endpoint- end of period II (between subjects trial) | Observations of parents and children as they interact with each other during a five minute homework task and during a 10 minute non-academic task. Interactions were recorded and later coded by trained observers. Observers counted number of parent and child behaviors. Percentages of behaviors as a function of total verbalizations (for praise, negative talk, demanding) or as a function of commands and questions (for impatient and responsive) were computed.Three subjects dropped prior to completing this assessment and one participant completed the other endpoint measures but not the DPICS, which is why the total N for this outcome is 23 at study endpoint. At end of period II (study endpoint), the medication group (n=10) was compared to the placebo group (N=13). |
| Secondary | Alabama Parenting Questionnaire (APQ) | baseline and week 4 | measures change in parenting practices.The APQ is a 42-item measure (each item ranges from 1/always to 5/never) on which parents are asked to indicate the frequency with which they implement the following parenting practices: involvement (10 items range 10-50- higher scores mean more parental involvement), positive parenting (6 items with range of 6 to 30 and higher scores indicate greater use of praise), poor monitoring/supervision (10 items with range of 10 to 50 and higher scores indicate less supervision/monitoring), inconsistent discipline(6 items with range of 6 to 30 and higher scores indicate greater problems with inconsistent discipline), and corporal punishment (3 items with range of 3-15 and greater scores indicate more use of corporal punishment). Items are rated on a 5-point scale, ranging from 1 ("never") to 5 ("always"). Items summed into composite scales. Within subject comparison of no medication baseline vs. optimal dose medication. |
| Secondary | Disruptive Behavior Disorders Rating Scale (DBD) | baseline and week 4 | Parent ratings of their child's symptoms of attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Measure consists of 45 items each rated on a Likert scale that ranges from 0 (not at all) to 3 (very much). Items are averaged to form adhd-inattention, adhd-hyperactive/impulsive, ODD, and CD scores.Within subject comparison of no medication baseline vs. optimal dose medication. ADHD subscale consists of 20 items with range of 0 to 60. ODD subscale consists of 9 items with range of 0 to 27. CD subscale consists of 15 items with range of 0 to 45. For all subscales, higher scores indicate more severe symptoms. |
| Secondary | Impairment Rating Scale (IRS) | baseline and week 4 | Parent ratings of their child's functioning and need for treatment in developmentally important domains. Ratings are completed using visual-analogue scales that are anchored at the low end by "no problems / no need for treatment" and at the high end by "extreme problem / definitely needs treatment." Visual analogue ratings for each subscale were converted to 0 to 6 scales with higher values indicating greater impairment and lower values indicating less impairment for each subscale.Within subject comparison of no medication baseline vs. optimal dose medication. |
| Secondary | Sheehan Disability Scale (SDS) | baseline and week 4 | The SDS consists of 3 self rated items assessing the degree to which symptoms affect work/school, social life, and family/home responsibilities. Items are rated on a 0 (not at all) to 10 (extremely) scale. Items were averaged into an overall disability score with range of 0 to 10 with higher scores indicating more severe disability.Within subject comparison of no medication baseline vs. optimal dose medication. |
| Secondary | Dyadic Parent-Child Interaction Coding System (DPICS) | weeks 4 and weeks 5 (period I within subjects trial) | Observations of parents and children as they interact with each other during a five minute homework task and during a 10 minute non-academic task. Interactions were recorded and later coded by trained observers. Observers counted number of parent and child behaviors with each parent-child dyad counted as one participant. Average number of behaviors per group were computed.This outcome was part of period I- the within subject comparison of all participating subjects once on placebo (n=26) and once with all subjects on active medication (N=26). (the 27th participant completed this phase but partial data was lost due to mechanical failure with video equipment so their data was not included). All adult participants received both placebo and active medication in this phase that comprised all of period 1. |
| Secondary | Dyadic Parent-Child Interaction Coding System (DPICS) - Behavior Percentages | weeks 4 and weeks 5 (period I within subjects trial) | Observations of parents and children as they interact with each other during a five minute homework task and during a 10 minute non-academic task. Interactions were recorded and later coded by trained observers. Observers counted number of parent and child behaviors with each parent-child dyad counted as one participant. Percentages of behaviors as a function of total verbalizations (for praise, negative talk, demanding) or as a function of commands and questions (for impatient and responsive) were computed. This outcome was part of period I- the within subject comparison of all participating subjects once on placebo (n=26) and once with all subjects on active medication (N=26). (the 27th participant completed this phase but partial data was lost due to mechanical failure with video equipment so their data was not included).

| Secondary | Pittsburgh Side Effect Rating Scale | baseline and end of dose optimization phase/week 4 | rates 13 potential adverse events of central nervous system stimulant medications on a 0-3 likert scale with 0=none 1=mild severity, 2=moderate severity, 3=severe severity. Form completed by participants at end of med optimization phase. Mean severity rating then averaged across 13 categories. This compares mean side effect severity at unmedicated baseline state vs. on optimal dose at week 3. Analysis includes all participants completing medication optimization. |
| Secondary | Adult ADHD Rating Scale (ADHD RS) | study endpoint- end of period II (between subjects trial) | measures change in all DSM (Diagnostic and Statistics Manual) IV ADHD symptoms on a 0 (least severe) to 3 (most severe) scale. Inattention and hyperactive/impulsive subscales each consist of 9 items with range of 0 to 27. Total Score consists of all 18 items rated 0 to 3 with range of 0 to 54. For all, higher scores indicate more symptoms. All information obtained during clinician interview of patient. At endpoint, the medication group (N=11) was compared to the placebo group (N=13). |
| Secondary | Parenting Stress Index (PSI)--Total Stress | study endpoint- end of period II (between subjects trial) | measures change in stress of parent child interactions and completed by the participant. The PSI is a measure of the source and degree of parenting stress (Abidin, 1995), which contains 120 items which are rated on a 1 (strongly disagree) to 5 (strongly agree) scale. 101 of these items are used to compute a total stress score (reported below) as the other 19 report on specific life stressors. Range is 101 to 505, for which higher scores indicate higher levels of stress. At endpoint, the medication group (N=9) was compared to the placebo group (N=13). |
| Secondary | Parenting Locus of Control (PLC) | study endpoint- end of period II (between subjects trial) | self completed parenting measure of the degree to which parents feel they can influence their child's behavior. Measure consists of 25 items each rated using a Likert scales that ranges from 1 ("strongly disagree") to 5 ("strongly agree"). Range is 25 to 125 with higher scores indicating greater parental control over their child's behavior (desired outcome). At endpoint, the medication group (N=9) was compared to the placebo group (N=13). |
| Secondary | Brown Attention Deficit Scale (BAADS) | study endpoint- end of period II (between subjects trial) | Measures executive functioning using 40 items each rated using a Likert Scale that ranges from 0 ("never") to 3 ("almost daily"). Activation, Attention and effort subscales are 9 items each with range of 0-27. Affect scale is 7 items (range 0-21), memory is 6 items (range 0-18) and total score is 40 items (range 0-120). All raw scores are then reported as T scores based on normative data with higher T scores indicating worse executive functioning. At endpoint, the medication group (N=10) was compared to the placebo group (N=13). |
| Secondary | Social Skills Rating System (SSRS) | study endpoint- end of period II (between subjects trial) | Measures child's interactions with peers and adults. Items rated using Likert scales that range from 0 ("never") to 2 ("often").At week 8, the medication group (N=10) was compared to the placebo group (N=11). There are two subscales: Problem Behaviors (18 items rated between 0-2 for total score range of 0 to 36) and Social Skills (40 items rated 0-2 with range for total score of 0-80). The total scores for these scales are reported as standard scores, with a population mean of 100 and standard deviation of 15. For problem behavior higher scores indicate worse behavior whereas for social skills, higher scores indicate more social (or better behavior). |
| Secondary | Disruptive Behavior Disorder Rating Scale (DBD) | study endpoint- end of period II (between subjects trial) | measures externalizing symptoms in children.measures externalizing symptoms in children completed by their primary caretaker who was a participant in the study.
