RESUMO

Severe temper outbursts (STO) in children are associated with impaired school and family functioning and may contribute to negative outcomes. These outbursts can be conceptualized as excessive frustration responses reflecting reduced emotion regulation capacity. The anterior cingulate cortex (ACC) has been implicated in negative affect as well as emotional control, and exhibits disrupted function in children with elevated irritability and outbursts. This study examined the intrinsic functional connectivity (iFC) of a region of the ACC, the anterior midcingulate cortex (aMCC), in 5- to 9-year-old children with STO (n = 20), comparing them to children with attention-deficit/hyperactivity disorder (ADHD) without outbursts (ADHD; n = 18). Additional analyses compared results to a sample of healthy children (HC; n = 18) and examined specific associations with behavioral and emotional dysregulation. Compared to the ADHD group, STO children exhibited reduced iFC between the aMCC and surrounding regions of the ACC, and increased iFC between the aMCC and precuneus. These differences were also seen between the STO and HC groups; ADHD and HC groups did not differ. Specificity analyses found associations between aMCC-ACC connectivity and hyperactivity, and between aMCC-precuneus iFC and emotion dysregulation. Disruption in aMCC networks may underlie the behavioral and emotional dysregulation characteristic of children with STO.

RESUMO

BACKGROUND: Social anxiety disorder (SAD) typically onsets in adolescence and is associated with multiple impairments. Despite promising clinical interventions, most socially anxious adolescents remain untreated. To address this clinical neglect, we developed a school-based, 12-week group intervention for youth with SAD, Skills for Academic and Social Success (SASS). When implemented by psychologists, SASS has been found effective. To promote dissemination and optimize treatment access, we tested whether school counselors could be effective treatment providers. METHOD: We randomized 138, ninth through 11th graders with SAD to one of three conditions: (a) SASS delivered by school counselors (C-SASS), (b) SASS delivered by psychologists (P-SASS), or (c) a control condition, Skills for Life (SFL), a nonspecific counseling program. Blind, independent, evaluations were conducted with parents and adolescents at baseline, post-intervention, and 5 months beyond treatment completion. We hypothesized that C-SASS and P-SASS would be superior to the control, immediately after treatment and at follow-up. No prediction was made about the relative efficacy of C-SASS and P-SASS. RESULTS: Compared to controls, adolescents treated with C-SASS or P-SASS experienced significantly greater improvement and reductions of anxiety at the end of treatment and follow-up. There were no significant differences between SASS delivered by school counselors and psychologists. CONCLUSION: With training, school counselors are effective treatment providers to adolescents with social anxiety, yielding benefits comparable to those obtained by specialized psychologists. Questions remain regarding means to maintain counselors' practice standards without external support.

RESUMO

BACKGROUND: The 'New Forest Parenting Package' (NFPP), an 8-week home-based intervention for parents of preschoolers with attention-deficit/hyperactivity disorder (ADHD), fosters constructive parenting to target ADHD-related dysfunctions in attention and impulse control. Although NFPP has improved parent and laboratory measures of ADHD in community samples of children with ADHD-like problems, its efficacy in a clinical sample, and relative to an active treatment comparator, is unknown. The aims are to evaluate the short- and long-term efficacy and generalization effects of NFPP compared to an established clinic-based parenting intervention for treating noncompliant behavior ['Helping the Noncompliant Child' (HNC)] in young children with ADHD. METHODS: A randomized controlled trial with three parallel arms was the design for this study. A total of 164 3-4-year-olds, 73.8% male, meeting DSM-IV ADHD diagnostic criteria were randomized to NFPP (N = 67), HNC (N = 63), or wait-list control (WL, N = 34). All participants were assessed at post-treatment. NFPP and HNC participants were assessed at follow-up in the next school year. Primary outcomes were ADHD ratings by teachers blind to and uninvolved in treatment, and by parents. Secondary ADHD outcomes included clinician assessments, and laboratory measures of on-task behavior and delay of gratification. Other outcomes included parent and teacher ratings of oppositional behavior, and parenting measures. (Trial name: Home-Based Parent Training in ADHD Preschoolers; Registry: ClinicalTrials.gov Identifier: NCT01320098; URL: http://www/clinicaltrials.gov/ct2/show/NCT01320098). RESULTS: In both treatment groups, children's ADHD and ODD behaviors, as well as aspects of parenting, were rated improved by parents at the end of treatment compared to controls. Most of these gains in the children's behavior and in some parenting practices were sustained at follow-up. However, these parent-reported improvements were not corroborated by teacher ratings or objective observations. NFPP was not significantly better, and on a few outcomes significantly less effective, than HNC. CONCLUSIONS: The results do not support the claim that NFPP addresses putative dysfunctions underlying ADHD, bringing about generalized change in ADHD, and its underpinning self-regulatory processes. The findings support documented difficulties in achieving generalization across nontargeted settings, and the importance of using blinded measures to provide meaningful assessments of treatment effects.

RESUMO

BACKGROUND: Children and adolescents who seek medical treatment for persistent physical distress often suffer from co-occurring anxiety disorders. Treatment options for this impaired population are limited. This study tests the feasibility and potential efficacy of a cognitive-behavioral intervention targeting pain and anxiety for youth with impairing functional physical symptoms and anxiety disorders presenting to pediatricians for medical care. METHODS: Children and adolescents (aged 8-16) experiencing somatic complaints, without an explanatory medical disorder (i.e., functional), were recruited from primary care and specialty (gastroenterologists and cardiologists) pediatricians. Forty children, primarily with gastrointestinal symptoms, who met criteria for a co-occurring anxiety disorder, were randomly assigned to a cognitive-behavioral treatment addressing pain and anxiety, Treatment of Anxiety and Physical Symptoms (TAPS), or to a waiting list control. RESULTS: TAPS was found to be an acceptable treatment for this population and was superior to the waiting list condition. Eighty percent of children in TAPS were rated as treatment responders by independent evaluators compared with none of the controls. Overall, self- and parent ratings indicated reductions in children's somatic discomfort and anxiety following intervention. TAPS participants maintained clinical gains 3 months following treatment. CONCLUSIONS: The study supports the feasibility and preliminary efficacy of a cognitive-behavioral intervention targeting co-occurring physical distress and anxiety in youth presenting for medical treatment. Such an approach has the potential to exert broad impact on children's dysfunction and to minimize exposure to invasive, ineffective, and costly medical procedures and treatments.

RESUMO

BACKGROUND: Although adolescent major depressive disorder (MDD) is acknowledged to be a heterogeneous disorder, no studies have reported on biological correlates of its clinical subgroups. This study addresses this issue by examining whether adolescent MDD with and without melancholic features (M-MDD and NonM-MDD) have distinct biological features in the kynurenine pathway (KP). The KP is initiated by pro-inflammatory cytokines via induction of the enzyme indoleamine 2,3-dioxygenase (IDO), which degrades tryptophan (TRP) into kynurenine (KYN). KYN is further metabolized into neurotoxins linked to neuronal dysfunction in MDD. Hypotheses were that, compared to healthy controls and to NonM-MDD adolescents, adolescents with M-MDD would exhibit: (i) increased activation of the KP [i.e., increased KYN and KYN/TRP (reflecting IDO activity)]; (ii) greater neurotoxic loads [i.e., increased 3-hydroxyanthranilic acid (3-HAA, neurotoxin) and 3-HAA/KYN (reflecting production of neurotoxins)]; and (iii) decreased TRP. We also examined relationships between severity of MDD and KP metabolites. METHODS: Subjects were 20 adolescents with M-MDD, 30 adolescents with NonM-MDD, and 22 healthy adolescents. MDD episode duration had to be >or= 6 weeks and Children's Depression Rating Scale-Revised (CDRS-R) scores were >or= 36. Blood samples were collected at AM after an overnight fast and analyzed using high-performance liquid chromatography. Group contrasts relied on analysis of covariance based on ranks, adjusted for age, gender, and CDRS-R scores. Analyses were repeated excluding medicated patients. Fisher's protected least significant difference was used for multiple comparisons. RESULTS: As hypothesized, KYN/TRP ratios were elevated and TRP concentrations were reduced in adolescents with M-MDD compared to NonM-MDD adolescents (p = .001 and .006, respectively) and to healthy controls (p = .008 and .022, respectively). These findings remained significant when medicated patients were excluded from the analyses. Significant correlations were obtained exclusively in the M-MDD group between KYN and 3-HAA/KYN and CDRS-R. CONCLUSIONS: Findings support the notion that adolescent M-MDD may represent a biologically distinct clinical syndrome.

RESUMO

Because of their high prevalence and their negative long-term consequences, child anxiety disorders have become an important focus of interest. Whether pathological anxiety and normal fear are similar processes continues to be controversial. Comparative studies of child anxiety disorders are scarce, but there is some support for the current classification of anxiety disorders in children and adolescents, except for generalized anxiety disorder. The greatly differing rates of anxiety disorders in child population studies, and of specific disorders in clinical samples, inconsistent findings regarding course, and disparate placebo response rates all suggest a need for more precise, validated, criteria for symptoms, distress, and impairment. Several treatments have documented efficacy, and promising prevention efforts are encouraging.

RESUMO

Identify correlates of nicotine dependence [lifetime (l) and ongoing (o)] in adults with attention-deficit/hyperactivity disorder (ADHD) in childhood. We conducted a 33-year prospective follow-up of boys (mean age 8) with combined type ADHD (n = 135/207, 65% original sample). Correlates of nicotine dependence in adulthood were selected from characteristics obtained in childhood and adolescence. Among selected childhood features, only immature behavior was significantly related to nicotine dependence (OR(o) = 0.29, p = 0.02), indexing decreased risk. In contrast, several adolescent variables significantly correlated (p < 0.01) with nicotine dependence at mean age 41, including alcohol substance use disorder (SUD, OR(l) = 4.97), non-alcohol SUD (OR(o) = 4.33/OR(l) = 10.93), parental antisocial personality disorder (OR(l) = 4.42), parental SUD (OR(l) = 3.58), dropped out of school (OR(l) = 2.29), impulsivity (OR(o) = 1.53/OR(l) = 1.59), hyperactivity (OR(o) = 1.38), and number of antisocial behaviors (OR(o) = 1.10/OR(l) = 1.14). Results highlight the role of adolescent psychopathology in the development of nicotine dependence, motivating prospective longitudinal efforts to better define the developmental trajectories of risk and protection.

RESUMO

OBJECTIVE: Offspring of parents with major depressive disorder face a threefold higher risk for major depression than offspring without such family histories. Although major depression is a significant cause of morbidity and mortality, neural correlates of risk for major depression remain poorly understood. This study compares amygdala and nucleus accumbens activation in children and adolescents at high and low risk for major depression under varying attentional and emotional conditions. METHOD: Thirty-nine juveniles, 17 offspring of parents with major depression (high-risk group) and 22 offspring of parents without histories of major depression, anxiety, or psychotic disorders (low-risk group) completed a functional magnetic resonance imaging study. During imaging, subjects viewed faces that varied in intensity of emotional expressions across blocks of trials while attention was unconstrained (passive viewing) and constrained (rate nose width on face, rate subjective fear while viewing face). RESULTS: When attention was unconstrained, high-risk subjects showed greater amygdala and nucleus accumbens activation to fearful faces and lower nucleus accumbens activation to happy faces (small volume corrected for the amygdala and nucleus accumbens). No group differences emerged in amygdala or nucleus accumbens activation during constrained attention. Exploratory analysis showed that constraining attention was associated with greater medial prefrontal cortex activation in the high-risk than in the low-risk group. CONCLUSIONS: Amygdala and nucleus accumbens responses to affective stimuli may reflect vulnerability for major depression. Constraining attention may normalize emotion-related neural function possibly by engagement of the medial prefrontal cortex; face-viewing with unconstrained attention may engage aberrant processes associated with risk for major depression.

RESUMO

Evidence suggests a relationship between parental depression and phobias in offspring as well as links between childhood fears and risk for major depression. This study examines the relationship between major depressive disorder (MDD) and anxiety disorders in parents and specific fears and phobias in offspring. Three hundred and eighteen children of parents with lifetime MDD, anxiety disorder, MDD+anxiety disorder, or neither were psychiatrically assessed via parent interview. Rates of specific phobias in offspring did not differ significantly across parental groups. Specific fears were significantly elevated in offspring of parents with MDD+anxiety disorder relative to the other groups (MDD, anxiety disorder, and controls, which did not differ). We failed to find increased phobias in offspring of parents with MDD without anxiety disorder. Elevated rates of specific fears in offspring of parents with MDD+anxiety disorder may be a function of more severe parental psychopathology, increased genetic loading, or unmeasured environmental influences.

RESUMO

This study investigates the relationship between childhood attention deficit hyperactivity disorder (ADHD) and later criminality. White boys (n=207, ages 6-12) with ADHD, free of conduct disorder, were assessed at ages 18 and 25 by clinicians who were blind to childhood status. A non-ADHD group served as comparisons. Lifetime arrest records were obtained when subjects were 38 years old for subjects who resided in New York State throughout the follow-up interval (93 probands, 93 comparisons). Significantly more ADHD probands than comparisons had been arrested (47% vs. 24%), convicted (42% vs. 14%), and incarcerated (15% vs. 1%). Rates of felonies and aggressive offenses also were significantly higher among probands. Importantly, the development of an antisocial or substance use disorder in adolescence completely explained the increased risk for subsequent criminality. Results suggest that even in the absence of comorbid conduct disorder in childhood, ADHD increases the risk for developing antisocial and substance use disorders in adolescence, which, in turn, increases the risk for criminal behavior in adolescence and adulthood.

RESUMO

This article presents long-term effects of a preventive intervention for young children at high risk for antisocial behavior. Ninety-two children (M age = 4 years) were randomly assigned to an 8-month family intervention or no-intervention control condition and assessed 4 times over a 24-month period. Intent-to-treat analyses revealed significant intervention effects on observed child physical aggression, and significant intervention effects found at the end of the program were maintained at follow-up for responsive parenting, harsh parenting and stimulation for learning. Parent ratings of child aggression did not show significant effects of intervention.

RESUMO

OBJECTIVE: Little is known of the factors that influence the course of childhood attention-deficit/hyperactivity disorder (ADHD). Objectives were to identify early features predictive of the adult outcome of children with ADHD. In the longest prospective follow-up to date of children with ADHD, predictors of multiple functional domains were examined: social, occupational, and overall adjustment and educational and occupational attainment. METHOD: White boys (6-12 years, mean age 8 years) with ADHD (N = 135), selected to be free of conduct disorder, were assessed longitudinally through adulthood (mean age 41) by clinicians blinded to all previous characteristics. Predictors had been recorded in childhood and adolescence (mean age 18). RESULTS: Childhood IQ was positively associated with several outcomes: educational attainment, occupational rank, and social and occupational adjustment. Despite their low severity, conduct problems in childhood were negatively related to overall function, educational attainment, and occupational functioning. Two other childhood features that had positive associations with adult adjustment were socioeconomic status and reading ability, which predicted educational attainment. Of multiple adolescent characteristics, 4 were significant predictors: antisocial behaviors predicted poorer educational attainment; educational goals were related to better overall function; early job functioning had a positive relation with social functioning; and early social functioning was positively related to occupational functioning. CONCLUSION: Other than childhood IQ, which predicted better outcomes in several domains, there were no consistent prognosticators of adult function among children with ADHD. Providing additional supports to children with relatively lower IQ might improve the adult functional outcome of children with ADHD. However, predicting the course of children with ADHD remains a challenge.

RESUMO

OBJECTIVE: Reports are mixed on the efficacy of omega-3 fatty acids (O3FA) for the treatment of major depressive disorder (MDD), with only limited data in adolescents. The present trial aimed to investigate systematically the efficacy of O3FA as a monotherapy, compared to a placebo, in adolescents with MDD. Secondarily, we explored O3FA effects on anhedonia, irritability, and suicidality-all key features of adolescent MDD. METHODS: Fifty-one psychotropic medication-free adolescents with DSM-IV-TR diagnoses of MDD (aged 12-19 years; 57% female) were randomized to receive O3FA or a placebo for 10 weeks. Data were collected between January 2006 and June 2013. O3FA and a placebo were administered on a fixed-flexible dose titration schedule based on clinical response and side effects. The initial dose of 1.2 g/d was increased 0.6 g/d every 2 weeks, up to a maximum of 3.6 g/d. Clinician-rated and self-rated depression severity, along with treatment response, served as primary outcome measures. Additionally, we examined O3FA effects on depression-related symptoms, including anhedonia, irritability, and suicidality. Treatment differences were analyzed via intent-to-treat analyses. RESULTS: O3FA were not superior to a placebo on any clinical feature, including depression severity and levels of anhedonia, irritability, or suicidality. Additionally, response rates were comparable between treatment groups. Within-treatment analyses indicated that both treatments were associated with significant improvement in depression severity on self- (O3FA: t = -4.38, P < .001; placebo: t = -3.52, P = .002) and clinician (O3FA: t = -6.47, P < .001; placebo: t = -8.10, P < .001) ratings. CONCLUSIONS: In adolescents with MDD, O3FA do not appear to be superior to placebo. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00962598.

RESUMO

OBJECTIVE: Proton magnetic resonance spectroscopy ((1)H-MRS) has been increasingly used to examine striatal neurochemistry in adult major depressive disorder. This study extends the use of this modality to pediatric major depression to test the hypothesis that adolescents with major depression have elevated concentrations of striatal choline and creatine and lower concentrations of N-acetylaspartate. METHOD: Fourteen adolescents (ages 12-19 years, eight female) who had major depressive disorder for at least 8 weeks and a severity score of 40 or higher on the Children's Depression Rating Scale-Revised and 10 healthy comparison adolescents (six female) group-matched for gender, age, and handedness were enrolled. All underwent three-dimensional 3-T (1)H-MRS at high spatial resolution (0.75-cm(3) voxels). Relative levels of choline, creatine, and N-acetylaspartate in the left and right caudate, putamen, and thalamus were scaled into concentrations using phantom replacement, and levels were compared for the two cohorts. RESULTS: Relative to comparison subjects, adolescents with major depressive disorder had significantly elevated concentrations of choline (2.11 mM versus 1.56 mM) and creatine (6.65 mM versus 5.26 mM) in the left caudate. No other neurochemical differences were observed between the groups. CONCLUSIONS: These findings most likely reflect accelerated membrane turnover and impaired metabolism in the left caudate. The results are consistent with prior imaging reports of focal and lateralized abnormalities in the caudate in adult major depression.

RESUMO

OBJECTIVE: A previous laboratory-based study found elevated cortisol levels in anxious children susceptible to CO(2)-induced panic, but the effects of parent diagnosis were not considered. The current home-based study tested the hypothesis that parental panic disorder and offspring response to CO(2) are associated with elevated cortisol levels in juvenile offspring. METHOD: A total of 131 offspring (ages 9-19) of parents with panic disorder, major depression, and no mental disorder underwent CO(2) inhalation. Parent and child diagnoses were assessed. Salivary cortisol was assayed before and after CO(2) inhalation. RESULTS: Neither parents with panic disorder, parents with major depression, or offspring anxiety predicted offspring cortisol levels. Independent of parent and child diagnoses, anxiety response to CO(2) predicted elevated cortisol levels in offspring. CONCLUSIONS: As in adults, anxiety response to CO(2) in juveniles is associated with elevated cortisol levels, but elevated cortisol levels are not related to parent or child diagnoses.

RESUMO

BACKGROUND: Carbon dioxide (CO(2)) sensitivity is postulated to be a familial risk marker of panic disorder (PD). Exaggerated responses to CO(2) inhalation have been reported in adults with PD and their unaffected adult relatives, as well as in clinic-referred children with anxiety disorders. OBJECTIVE: To test in a family-based design whether CO(2) hypersensitivity is a familial risk marker for PD and associated with current anxiety disorders in children and adolescents. SETTING AND PARTICIPANTS: One hundred forty-two offspring (aged 9-19 years) of parents with PD, major depressive disorder, or no disorder. Forty-five (32%) had a current anxiety disorder, excluding specific phobia. DESIGN AND MAIN OUTCOME MEASURES: Parents and offspring received diagnostic assessments. Offspring underwent 5% CO(2) inhalation at home. Panic symptoms and panic attacks were rated with the Acute Panic Inventory at baseline, while anticipating CO(2) delivery ("threat"), and during CO(2) inhalation. Respiratory rate and volume were measured with spirometry. RESULTS: No group differences were found in Acute Panic Inventory ratings at baseline or in respiratory measures during threat. Risk for PD was not associated with CO(2) sensitivity (panic symptoms and respiratory physiologic response). During CO(2) inhalation, offspring with anxiety disorders, relative to offspring without anxiety disorders, experienced significantly more panic symptoms and panic attacks, as well as elevated respiratory rates. During threat, panic symptoms were significantly and independently associated with both parental PD and offspring anxiety disorders. CONCLUSIONS: No support was obtained for CO(2) hypersensitivity as a familial risk marker for PD in children and adolescents. Links between childhood anxiety disorders and CO(2) sensitivity were replicated. Familial risk for PD in children and adolescents may be associated with vulnerability to anticipatory anxiety.

RESUMO

OBJECTIVE: To examine whether childhood attention-deficit/hyperactivity disorder (ADHD) predicts homelessness in adulthood, and whether the persistence of childhood ADHD through adolescence influences the likelihood of homelessness. METHOD: A 33-year prospective, controlled, follow-up was performed of clinic-referred, 6- to 12-year-old boys of white ethnicity with ADHD (probands; mean = 8), at a mean age of 41 years (follow-up [FU] = 41). Comparisons, children without ADHD from the same medical center, were matched for age and socioeconomic status (SES). Both groups were evaluated at a mean age of 18 years (FU18). Homelessness was assessed at FU41 in 134 of 207 probands (65%) and 136 of 178 (76%) comparisons. We tested the following: the relationship between childhood ADHD and homelessness; whether adolescent dysfunctions (conduct disorder, non-alcohol substance use disorder, arrests, and school dropout) accounted for this relationship, if found; and whether ADHD that persisted through FU18 elevated probands' homelessness rate. RESULTS: Probands had significantly higher rates of homelessness than comparisons (23.7% vs. 4.4%; χ21 = 21.15, df = 1, p < .001). In a multivariate analysis, including childhood ADHD and covariates, the probands' significant elevation of homelessness remained (odds ratio [OR] = 3.60, 95% CI = 1.32-9.76, p = .01). Probands with persistent ADHD through adolescence had significantly more homelessness than remitted probands (χ21 = 12.73, p < .001), but this relationship was no longer significant when conduct disorder at FU18 was controlled (OR = 1.97, 95% CI = 0.89-4.38, p = .09). CONCLUSION: Among boys of white ethnicity who were followed into adulthood, childhood ADHD was associated with an elevated rate of homelessness. Findings point to the need for clinical monitoring of childhood ADHD through adolescence, even when ADHD does not persist, in hopes of mitigating a cascade of malfunction that includes homelessness.

RESUMO

OBJECTIVE: To examine the association of adolescent asthma-related anxiety, social anxiety, separation anxiety, and caregiver asthma-related anxiety with asthma care by urban adolescents. METHODS: Participants were 386 ethnic minority adolescents (mean age 12.8 years) with persistent asthma and their caregivers. Adolescents reported what they do to prevent asthma symptoms and to manage acute symptoms, and if they or their caregiver is responsible for their asthma care. Adolescents completed the Youth Asthma-Related Anxiety Scale, and the social and separation anxiety subscales of the Screen for Child Anxiety and Emotional Disorders (SCARED); caregivers completed the Parent Asthma-Related Anxiety Scale. Linearity of the associations was assessed by generalized additive models. When there was no evidence for nonlinearity, linear mixed effects models were used to evaluate the effects of the predictors. RESULTS: Adolescent asthma-related anxiety had a strong curvilinear relationship with symptom prevention (P < .001). Adolescents took more prevention steps as their anxiety increased, with a plateau at moderate anxiety. There was a linear relationship of adolescent asthma-related anxiety to symptom management (ß = 0.03, P = .021) and to asthma responsibility (ß = 0.11, P = .015), and of caregiver asthma-related anxiety to adolescent symptom prevention (ß = 0.04, P = .001). Adolescent social and separation anxiety had weak to no relationship with asthma care. Results remained consistent when controlling for each of the other anxieties. CONCLUSIONS: Asthma-related anxiety plays an important, independent role in asthma care. When low, adolescents may benefit from increased support from caregivers and awareness of the consequences of uncontrolled asthma. When elevated, health providers should ensure the adolescents are not assuming responsibility for asthma care prematurely.

RESUMO

OBJECTIVE: Panic disorder (PD) has been linked to perturbed processing of threats. This study tested the hypotheses that offspring of parents with PD and offspring with anxiety disorders display relatively greater sensitivity and attention allocation to fear provocation. METHOD: Offspring of adults with PD, major depressive disorder (MDD), or no disorder (ages 9-19) viewed computer-presented face photographs depicting angry, fearful, and happy faces. Offspring rated (1) subjectively experienced fear level, (2) how hostile the face appeared, and (3) nose width. Attention allocation was indexed by latency to perform ratings. RESULTS: Compared with offspring of parents without PD (n = 79), offspring of PD parents (n = 65) reported significantly more fear and had slower reaction times to rate fear, controlling for ongoing anxiety disorder in the offspring. Offspring with an anxiety disorder (n = 65) reported significantly more fear than offspring without an anxiety disorder but not when parental PD was controlled. Social phobia but no other anxiety disorder in offspring was associated with slower reaction times for fear ratings (but not greater fear ratings). Parental PD and offspring social phobia independently predicted slower reaction time. CONCLUSIONS: Results support an association between parental PD and offspring responses to fear provocation. Social phobia in children may have a specific relationship to allocation of attention to subjective anxiety during face viewing.
