Title: Treatments for Fathers With Attention Deficit/Hyperactivity Disorder (ADHD) and Their At-Risk Children (Fathers Too)
Brief Summary: In contrast to mothers with Attention Deficit/Hyperactivity Disorder (ADHD), the impact of paternal ADHD in families and children with ADHD symptoms has not been studied, despite the prevalence of ADHD in males. Thus, the investigators do not know the feasibility, impact on treatment on the family and child, and effects of treating fathers relative to mothers with ADHD. Paternal ADHD is associated with negative parenting and child conduct problems.

The investigators hypothesize that successfully treating parental ADHD in fathers will have a beneficial effects on the family that will extend to the child. Specifically, the investigators believe that stimulant medication ((Lisdexamfetamine (LDX) or a different ADHD medication if poor response to LDX) with fathers will reduce father's ADHD symptoms and improve parenting. Effects of stimulant treatment of fathers will be compared to Behavioral Parent Training (BPT) on parenting, and paternal and child outcomes in fathers with ADHD who have children between the ages of 3 -8.

As in the investigator's previous work, the investigators will bank paternal and child DNA and RNA for later examination of pharmacogenetic and epigenetic effects (i.e. RNA) of stimulant response.

C: Inclusion Criteria:

Adults meeting DSM-IV-Text Revision criteria for ADHD, the Utah Criteria for ADHD, and experiencing at least moderate impairment (a score of 4 or greater on the CGI-Severity Scale for ADHD at both Screening and Baseline visits) will be enrolled. Other criteria include:

1. Subjects ages 18 to 65, inclusive;
2. Female subjects are eligible to enter and participate in this study only if:

   1. She is of non-childbearing potential; has a male sexual partner who is surgically sterilized; is on implant of levonorgestrel, injectable progesterone, or an oral contraceptive; has an intrauterine device (IUD); or is sexually inactive with a male partner.
   2. Or agrees to use a double barrier method of contraception (any combination of physical and chemical methods) and has a negative urine pregnancy test at screening interview.
3. Subject must be in general good health as determined by medical history, ECG, and other analysis that, in the judgment of the study physician, would confirm the patient's good health.
4. Subjects must read and write at a level sufficient to provide written informed consent and complete study-related materials.

Exclusion Criteria:

* Subjects will not be eligible for inclusion in this study if any of the following criteria apply:

  1. Subjects with other current DSM-IV Axis I Disorders including Current or lifetime history of psychosis, current bipolar disorder type I, current Major Depressive Disorder, and Current Anxiety Disorder (unless in the opinion of clinic physician ADHD is the primary disorder and causes the disability seen in the patient);
