Parenting in mothers with and without attention-deficit/hyperactivity disorder

The authors examined the impact of maternal attention-deficit/hyperactivity disorder (ADHD) on parenting behaviors. Sixty mothers between the ages of 31 and 50 with (n = 30) and without (n = 30) ADHD and their 8- to 14-year-old children with ADHD completed self-report and laboratory measures of monitoring of child behavior, consistency in parenting, and parenting problem-solving abilities. These parenting behaviors were selected because of their established links to the development of child behavior problems. As predicted, mothers with ADHD were found to be poorer at monitoring child behavior and less consistent disciplinarians compared with mothers without ADHD. There was some evidence to support the prediction that mothers with ADHD were less effective at problem solving about childrearing issues than control mothers. The differences between the 2 groups of mothers persisted after child oppositional and conduct-disordered behavior were controlled. These results indicate that parenting is an area of functioning that requires more attention in adult ADHD research.     

Validity of the parenting scale for parents of children with attention-deficit/hyperactivity disorder

The present study examined the validity of the parenting scale for parents of elementary school-aged children with attention-deficit/hyperactivity disorder (ADHD). Parents from 109 families with children who had been diagnosed with ADHD (106 mothers and 93 fathers) and from 70 families with non-problem children (69 mothers and 59 fathers) completed the parenting scale and reported on their children's behavior problems. Factor analyses revealed two interpretable factors for both mothers and fathers, corresponding to the overreactivity and laxness factors identified in previous studies of the parenting scale. Overreactivity and laxness scores were significantly higher for mothers and fathers of ADHD children than of non-ADHD children; this effect appeared to be accounted for by comorbid aggression and conduct problems among ADHD children. Results support the validity of the parenting scale for use with parents of ADHD children.     

Parenting stress among families of children with attention deficit hyperactivity disorder

Prior research has shown that parenting stress levels can be quite high among families of children with attention deficit hyperactivity disorder (ADHD). This study investigated the degree to which such stress was related not only to the child's ADHD, but also to various other child, parent, and family-environment circumstances. Multimethod assessments were conducted on 104 clinic-referred children with ADHD. Data collected from these subjects were entered into hierarchical multiple-regression analyses, utilizing the Parenting Stress Index as the criterion. The results showed that child and parent characteristics accounted for a substantial portion of the variance in overall parenting stress. The child's oppositional-defiant behavior and maternal psychopathology were especially potent predictors. The severity of the child's ADHD, the child's health status, and maternal health status also emerged as significant predictors. These findings are discussed in terms of their impact upon the clinical management of children with ADHD.The authors are grateful to Mary Maher and Paula Nevins for their assistance in collecting and coding the data. The authors would also like to thank Dr. Kenneth Fletcher for his helpful comments regarding the statistical analyses.     

Gait control in children with attention-deficit/hyperactivity disorder

The current profile of gait control in children with ADHD is incomplete and predominately based on children walking forward at a self-selected pace. There are no studies of potential gait deficits in this clinical population when walking in different directions in combination with varying rates of stepping that are freely selected and entrained to an external stimulus. The purpose of the current study was to address this lack of information by assessing gait of children aged 7–17 years with (n = 17) and without (n = 26) ADHD. Participants walked forward and backward along an electronically instrumented carpet at a self-selected stepping rate and in synchrony to a metronome that dictated an increased and decreased stepping rate. Using repeated measures analysis of covariance (ANCOVA) to assess spatiotemporal gait parameters, results showed that children with ADHD exhibited a significantly exaggerated, toes ‘turned out,’ foot position for all walking conditions compared to typically developing children. When walking backward, children with ADHD produced an increased step width, higher stepping cadence, and increased velocity. Additionally, coefficient of variation ratios indicated that children with ADHD produced greater variability of velocity, cadence, and step time for all walking conditions, and greater variability for stride length when walking at an increased stepping rate. Results were interpreted in terms of clinical significance and practical ramifications that inform rehabilitation specialists in designing therapies that ameliorate the reported gait deficits.     

Parenting stress in parents of children with attention-deficit hyperactivity disorder and parents of children with learning disabilities

Parenting a child with ADHD can challenge parenting resources and coping. Increasingly, researchers are examining the relationship between the behavior of the child with ADHD and family functioning. While studies have shown inceased parenting stress in parents of children with ADHD, these studies have compared children with ADHD to non-disabled children. This study compares reports of parenting stress among mothers of children with ADHD, mothers of children with learning disabilities and mothers of non-referred children. Results showed that parenting stress was highest for mothers of children with ADHD. Increased parenting stress was associated with child characteristics and, in particular, with externalizing behavior problems.     

Cognitive-behavioral depression treatment for mothers of children with attention-deficit/hyperactivity disorder

An adaptation of the Coping With Depression Course (CWDC) was evaluated in mothers of children with attention-deficit/hyperactivity disorder (ADHD), a population at risk for depression. Mothers were randomly assigned to receive the CWDC either immediately following an intensive summer treatment program targeting their child's behavior or after a wait-list period. Measures of maternal functioning, cognitions about child behavior, parent-child and marital relationship quality, child behavior, and ADHD-related family impairment were obtained at pretreatment, posttreatment, and 5-month follow-up. The CWDC resulted in improvements in maternal depressive symptoms, maternal self-esteem, child-related cognitions, and family impairment at posttreatment compared to a wait-list control group that were maintained at follow-up. Findings suggest that the CWDC is a promising intervention for mothers of children with ADHD, particularly those with current depressive symptomatology.     

ERPs and behavioral inhibition in a Go/No-go task in children with attention-deficit hyperactivity disorder

In order to study the behavioral responses and the brain inhibition process in children with attention-deficit hyperactivity disorder (ADHD), Event-Related Potentials (ERPs) were recorded from 30 scalp electrodes in 21 ADHD and 21 normal boys during performing a Go/No-go task. ADHD children made fewer correct responses to both Go and No-go stimuli than normal controls. The frontal N2 amplitude was larger for No-go stimuli than Go stimuli in both groups, reflecting inhibition of responding. Smaller N2 amplitudes to No-go stimuli were found in ADHD children, but only when the Go/No-go task was performed after a first stimulus-response compatibility (SRC) task. In addition, the controls exhibited a prolonged N2 only when the Go/No-go task was performed second. However, the ADHD subjects exhibited this prolonged N2 when the task was first, but not when it was second. These results suggest an inhibitory regulation problem rather an inhibition deficit in ADHD children.     

A school-based parenting program for children with attention-deficit/hyperactivity disorder: Impact on paternal caregivers

Engaging male caregivers within school settings is a major need within the educational field. Paternal engagement may be particularly important for children with attention-deficit/hyperactivity disorder (ADHD). Children with ADHD have increased risk for a number of poor educational outcomes, which may be attenuated by the benefits of positive male caregiver involvement. The Coaching Our Acting Out Children: Heightening Essential Skills (COACHES) program has been illustrated to be an effective approach for engaging, retaining, and improving the parenting of male caregivers of children with ADHD in clinical settings. The present study reports on the efficacy of the COACHES in Schools program, an adaptation intended for deployment in elementary school settings. Sixty-one male caregivers were randomly assigned to COACHES in Schools or a waitlist control. Results indicated that male caregivers in COACHES in Schools used significantly more praise and less negative talk in a parent-child activity relative to male caregivers in the waitlist control at post-treatment and one-month follow-up. Distal outcomes related to child behavior at home and at school were not significantly different. Implications of the results for future studies and continued efforts to engage male caregivers within school settings are discussed.     

Non-stimulant treatment of attention-deficit/hyperactivity disorder

Stimulants are a highly efficacious and safe treatment for attention-deficit/hyperactivity disorder (ADHD), with 75% to 90% of patients responding well if two different stimulants (amphetamine and methylphenidate) are used. Nonetheless, a subset of ADHD patients will either fail to respond to stimulants or have side effects that preclude their use (tics, severe loss of appetite, marked insomnia). For such patients, there are a number of non-stimulant agents that serve as second-line treatments. Tricyclic antidepressants (TCAs) are the most studied of these drugs. They are superior to placebo in the treatment of ADHD and may reduce abnormal movements in patients with ADHD/tic disorder. TCAs often produce side effects of sedation, dry mouth, and constipation. Bupropion is superior to placebo in the treatment of ADHD and has a more favorable side-effect profile than the TCAs. A new selective norepinephrine reuptake inhibitor, atomoxetine, has been shown to be efficacious in the treatment of ADHD and has recently received an approvable letter from the Food and Drug Administration. The a-agonists clonidine and guanfacine have also been used as alternative agents in ADHD, though the controlled data are more limited. A recent controlled clinical trial suggests a combination of methylphenidate and clonidine has advantages in the treatment of comorbid ADHD and tics over either medication alone. Clinical guidelines for each of these agents, as well as their use in combination with stimulants in comorbid conditions, will be discussed.     

Maternal depression and early positive parenting predict future conduct problems in young children with attention-deficit/hyperactivity disorder

Children with attention-deficit/hyperactivity disorder (ADHD) are at risk for adverse outcomes such as substance abuse and criminality, particularly if they develop conduct problems. Little is known about early predictors of the developmental course of conduct problems among children with ADHD, however. Parental psychopathology and parenting were assessed in 108 children who first met Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for ADHD at 4-7 years old. When demographic variables and baseline ADHD and conduct problems were controlled, maternal depression predicted conduct problems 2-8 years following the initial assessment, whereas positive parenting during the structured parent- child interaction task predicted fewer future conduct problems. These findings suggest that maternal depression is a risk factor, whereas early positive parenting is a protective factor, for the developmental course of conduct problems among children with ADHD.     

Predictors of physical aggression in children with attention-deficit/hyperactivity disorder

The present investigation examined factors that predict physical aggression in children with attention-deficit/hyperactivity disorder (ADHD). Stepwise, multiple regression-analyses were used to examine predictors of children's physical aggression as rated by parents at a 1-year follow-up point and by teachers at both 1- and 2-year follow-up points. Early parent and teacher ratings of verbal aggression (ie, cursing, teasing, and threatening) accounted for the greatest proportion of the variance in physical aggression ratings obtained at follow-up. None of the other predictor variables, including early ratings of physical aggression and ADHD behaviors, contributed significant additional variance beyond that accounted for by early verbal aggression ratings. Temporal and cross-informant analyses revealed that the relationship between verbal aggression and later physical aggression was situation-specific for teacher ratings but not parent ratings. Although physical aggression may emerge early in development, these data suggest that verbal aggression represents a stable, temperamental characteristic that may be of greater value than early physical aggression for predicting later physically aggressive acts.     

Cross-lateralisation in children with attention-deficit/hyperactivity disorder and motor skill performance

Cross-lateralisation and increased motor difficulties have been reported in children with attention-deficit/hyperactivity disorder (ADHD). Nevertheless, the question of how crossed (i.e. mixed preference) or uncrossed (i.e. same side preference) lateralisation impacts motor performance in children with ADHD has yet to be examined. In this study, previously validated observational measures of hand and foot preference were used to identify right-handed children with ADHD who display cross- (n = 29) and uncross-lateralisation (n = 31). An uncross-lateralised typically developing (TD) group (n = 32) was also identified, and included as a control. Motor performance was assessed with seven valid and reliable fine and gross motor tasks performed with both preferred and non-preferred limbs. Group, task and sex-related effects were examined. Findings revealed that male (but not female) cross-lateralised children with ADHD performed significantly worse, respectively, in two of the fine motor tasks (spiral tracing [p < .01], and dot filling [p < .05]). Results suggest that cross-lateralised hand and foot preference may affect complex motor skills in male children with ADHD. Furthermore, characteristics of ADHD may manifest differently in male and female children. Findings highlight the importance of considering both hand and foot preference when targeting motor interventions for children with ADHD.     

Preschoolers at risk for attention-deficit hyperactivity disorder and oppositional defiant disorder: family,parenting, and behavioral correlates

This community study assigned 129 4-year-olds to groups at risk for attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), both ADHD and ODD, or no problems. Mothers of children at risk for ODD reported more family dysfunction, felt less competent as parents, suggested fewer solutions to child behavior problems, demonstrated a less assertive approach to child management, and reported more child internalizing problems than did mothers of children not elevated on ODD symptoms. Mothers of children at risk for ADHD reported higher personal depression scores than did those of the non-ADHD subgroup. Children at risk for ADHD evidenced the most difficulties in school where teachers reported more social behavior, classroom management, and internalizing problems relative to other children not at risk for ADHD. When solving child management problems, mothers of children in all groups suggested twice as many controlling/negative management strategies as positive/preventive strategies. In addition, faced with oppositional and conduct problems, mothers of children in all groups increased controlling/negative suggestions and decreased positive/preventive suggestions. Mothers of girls at risk for ADHD, ODD, and ADHD/ODD gave more rewards per positive behavior than did mothers of boys.     

Autonomic correlates of attention-deficit/hyperactivity disorder and oppositional defiant disorder in preschool children

Numerous studies have revealed autonomic underarousal in conduct-disordered adolescents and antisocial adults. It is unknown, however, whether similar autonomic markers are present in at-risk preschoolers. In this study, the authors compared autonomic profiles of 4- to 6-year-old children with attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD; n = 18) with those of age-matched controls (n = 20). Children with ADHD and ODD exhibited fewer electrodermal responses and lengthened cardiac preejection periods at baseline and during reward. Although group differences were not found in baseline respiratory sinus arrhythmia, heart rate changes among ADHD and ODD participants were mediated exclusively by parasympathetic withdrawal, with no independent sympathetic contribution. Heart rate changes among controls were mediated by both autonomic branches. These results suggest that at-risk preschoolers are autonomically similar to older externalizing children.
