Parent-child interaction therapy for Puerto Rican preschool children with ADHD and behavior problems: a pilot efficacy study. - Family process
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). Participants from both groups completed pretreatment and posttreatment assessments. Outcome measures included child's ADHD symptoms and behavior problems, parent or family functioning, and parents' satisfaction with treatment. ANCOVAs with pretreatment measures entered as covariates were significant for all posttreatment outcomes, except mother's depression, and in the expected direction (p < .01). Mothers reported a highly significant reduction in pretreatment hyperactivity and inattention and less aggressive and oppositional-defiant behaviors, conduct problems assessed as problematic, parenting stress associated with their child's behavior, and an increase in the use of adequate parenting practices. For the WL group, there were no clinically significant changes in any measure. Treatment gains obtained after treatment were maintained at a 3.5-month follow-up assessment. PCIT seems to be an efficacious intervention for Puerto Rican families who have young children with significant behavior problems.
Adaptation of parent-child interaction therapy for Puerto Rican families: a preliminary study. - Family process
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. Both quantitative and qualitative results suggest that PCIT seems to be an acceptable intervention for this population, with some minor changes. Parents reported a high level of satisfaction, a significant reduction in children's externalizing behavior problems, and reduction of parenting stress and improvement in their parenting practices. Psychologists also evaluated positively the treatment protocol and recommended its use. Results from this study may inform clinicians and researchers who work with Latino families about relevant issues to be considered to promote their participation in behavioral family interventions and to enhance their acceptability and effectiveness.
Comparison of the DSM-IV combined and inattentive types of ADHD in a school-based sample of Latino/Hispanic children. - Journal of child psychology and psychiatry, and allied disciplines
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.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).Both ADHD groups were impaired on academic achievement measures, presented more ADHD-type behaviors during math and vigilance tasks, and exhibited greater internalizing symptoms. The IT group had a later onset of inattention symptoms, presented more sluggish cognitive tempo symptoms, was less prone to initiate social interactions or to be assertive and more self-controlled in social interchanges, was less likely to have externalizing behaviors, had mothers who reported less child-related family stress, and was less impaired in their adaptive functioning.Findings supported the construct validity of ADHD in this culturally different sample and suggested that the CT and IT represent distinct disorders.
Time estimation and performance on reproduction tasks in subtypes of children with attention deficit hyperactivity disorder. - Journal of clinical child and adolescent psychology : the official journal for the Society of Clinical Child and Adolescent Psychology, American Psychological Association, Division 53
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. Although various measures of executive functioning did not make significant unique contributions to time estimation performance, those of interference control and nonverbal working memory did so to the time-reproduction task. Findings suggest that ADHD is associated with a specific impairment in the capacity to reproduce rather than estimate time durations and that this may be related to the children's deficits in inhibition and working memory.
