This study evaluates the initial efficacy of the Parent-Child Interaction Therapy (PCIT) for Puerto Rican preschool children aged 4-6 years with a diagnosis of attention-deficit/hyperactivity disorder (ADHD), combined or predominantly hyperactive type, and significant behavior problems. Thirty-two families were randomly assigned to PCIT (n = 20) or a 3.5-month waiting-list condition (WL; n = 12).

This study examines how parent-child interaction therapy (PCIT) was adapted for Puerto Rican parents of children aged 4-6 with hyperactivity and other significant behavior problems. Four steps were followed: (1) translation and preliminary adaptation of the treatment manual, (2) application of the treatment to 9 families as part of an exploratory study using repeated measures, (3) treatment revision and refinement, and (4) in-depth interviews with parents (n=15) and clinical psychologists (n=5) from Puerto Rico who provided feedback on treatment process and components. Throughout this process, cultural elements and modifications were recommended to be incorporated into the treatment protocol.

Background: The aim of this investigation was to examine the construct validity and distinctiveness of the inattentive type (IT) and combined type (CT) of Attention-Deficit/Hyperactivity Disorder (ADHD) in a Latino/Hispanic sample.

Method: A comprehensive assessment was conducted with a clinically diagnosed school-based sample of 98 children aged 6 to 11 (CT=44; IT=25; control group=29).

Results: Both ADHD groups were impaired on academic achievement measures, presented more ADHD-type behaviors during math and vigilance tasks, and exhibited greater internalizing symptoms.

This study compared Hispanic children (ages 7 to 11) with combined type (CT, n=33) and inattentive type (IT, n=21) attention deficit hyperactivity disorder (ADHD) and a control group (n=25) on time-estimation and time-reproduction tasks. The ADHD groups showed larger errors in time reproduction but not in time estimation than the control group, and the groups did not differ from each other on their performance on this task. Individual differences could not be accounted for by oppositional-defiance ratings and low math or reading scores.
