ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: To compare BMI and obesity rates in fully grown men with and without childhood attention-deficit/hyperactivity disorder (ADHD). We predicted higher BMI and obesity rates in: (1) men with, versus men without, childhood ADHD; (2) men with persistent, versus men with remitted, ADHD; and (3) men with persistent or remitted ADHD versus those without childhood ADHD. METHODS: Men with childhood ADHD were from a cohort of 207 white boys (referred at a mean age of 8.3 years), interviewed blindly at mean ages 18 (FU18), 25 (FU25), and 41 years (FU41). At FU18, 178 boys without ADHD were recruited. At FU41, 111 men with childhood ADHD and 111 men without childhood ADHD self-reported their weight and height. RESULTS: Men with childhood ADHD had significantly higher BMI (30.1 ± 6.3 vs 27.6 ± 3.9; P = .001) and obesity rates (41.4% vs 21.6%; P = .001) than men without childhood ADHD. Group differences remained significant after adjustment for socioeconomic status and lifetime mental disorders. Men with persistent (n = 24) and remitted (n = 87) ADHD did not differ significantly in BMI or obesity rates. Even after adjustment, men with remitted (but not persistent) ADHD had significantly higher BMI (B: 2.86 [95% CI: 1.22 to 4.50]) and obesity rates (odds ratio: 2.99 [95% CI: 1.55 to 5.77]) than those without childhood ADHD. CONCLUSIONS: Children with ADHD are at increased risk of obesity as adults. Findings of elevated BMI and obesity rates in men with remitted ADHD require replication.

ABSTRACT

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is increasingly conceived as reflecting altered functional and structural brain connectivity. The latter can be addressed with diffusion tensor imaging (DTI). We examined fractional anisotropy (FA), a DTI index related to white matter structural properties, in adult male subjects diagnosed with ADHD in childhood (probands) and matched control subjects without childhood ADHD. Additionally, we contrasted FA among probands with and without current ADHD in adulthood and control subjects. METHODS: Participants were from an original cohort of 207 boys and 178 male control subjects. At 33-year follow-up, analyzable DTI scans were obtained in 51 probands (41.3 ± 2.8 yrs) and 66 control subjects (41.2 ± 3.1 yrs). Voxel-based FA was computed with tract-based spatial statistics, controlling for multiple comparisons. RESULTS: Probands with childhood ADHD exhibited significantly lower FA than control subjects without childhood ADHD in the right superior and posterior corona radiata, right superior longitudinal fasciculus, and in a left cluster including the posterior thalamic radiation, the retrolenticular part of the internal capsule, and the sagittal stratum (p<.05, corrected). Fractional anisotropy was significantly decreased relative to control subjects in several tracts in both probands with current and remitted ADHD, who did not differ significantly from each other. Fractional anisotropy was not significantly increased in probands in any region. CONCLUSIONS: Decreased FA in adults with childhood ADHD regardless of current ADHD might be an enduring trait of ADHD. White matter tracts with decreased FA connect regions involved in high-level as well as sensorimotor functions, suggesting that both types of processes are involved in the pathophysiology of ADHD.

ABSTRACT

OBJECTIVE: To test whether children with attention-deficit/hyperactivity disorder (ADHD), free of conduct disorder (CD) in childhood (mean = 8 years), have elevated risk-taking, accidents, and medical illnesses in adulthood (mean = 41 years); whether development of CD influences risk-taking during adulthood; and whether exposure to psychostimulants in childhood predicts cardiovascular disease. We hypothesized positive relationships between childhood ADHD and risky driving (in the past 5 years), risky sex (in the past year), and between risk-taking and medical conditions in adulthood; and that development of CD/antisocial personality (APD) would account for the link between ADHD and risk-taking. We report causes of death. METHOD: Prospective 33-year follow-up of 135 boys of white ethnicity with ADHD in childhood and without CD (probands), and 136 matched male comparison subjects without ADHD (comparison subjects; mean = 41 years), blindly interviewed by clinicians. RESULTS: In adulthood, probands had relatively more risky driving, sexually transmitted disease, head injury, and emergency department admissions (p< .05-.01). Groups did not differ on other medical outcomes. Lifetime risk-taking was associated with negative health outcomes (p = .01-.001). Development of CD/APD accounted for the relationship between ADHD and risk-taking. Probands without CD/APD did not differ from comparison subjects in lifetime risky behaviors. Psychostimulant treatment did not predict cardiac illness (p = .55). Probands had more deaths not related to specific medical conditions (p = .01). CONCLUSIONS: Overall, among children with ADHD, it is those who develop CD/APD who have elevated risky behaviors as adults. Over their lifetime, those who did not develop CD/APD did not differ from comparison subjects in risk-taking behaviors. Findings also provide support for long-term safety of early psychostimulant treatment.

ABSTRACT

CONTEXT Prospective studies of childhood attention-deficit/hyperactivity disorder (ADHD) have not extended beyond early adulthood. OBJECTIVE To examine whether children diagnosed as having ADHD at a mean age of 8 years (probands) have worse educational, occupational, economic, social, and marital outcomes and higher rates of ongoing ADHD, antisocial personality disorder (ASPD), substance use disorders (SUDs), adult-onset psychiatric disorders, psychiatric hospitalizations, and incarcerations than non-ADHD comparison participants at a mean age of 41 years. DESIGN Prospective, 33-year follow-up study, with masked clinical assessments. SETTING Research clinic. PARTICIPANTS A total of 135 white men with ADHD in childhood, free of conduct disorder, and 136 men without childhood ADHD (65.2% and 76.4% of original cohort, respectively). MAIN OUTCOME MEASURES Occupational, economic, and educational attainment; marital history; occupational and social functioning; ongoing and lifetime psychiatric disorders; psychiatric hospitalizations; and incarcerations. RESULTS Probands had significantly worse educational, occupational, economic, and social outcomes; more divorces; and higher rates of ongoing ADHD (22.2% vs 5.1%, P < .001), ASPD (16.3% vs 0%, P < .001), and SUDs (14.1% vs 5.1%, P = .01) but not more mood or anxiety disorders (P = .36 and .33) than did comparison participants. Ongoing ADHD was weakly related to ongoing SUDs (ϕ = 0.19, P = .04), as well as ASPD with SUDs (ϕ = 0.20, P = .04). During their lifetime, probands had significantly more ASPD and SUDs but not mood or anxiety disorders and more psychiatric hospitalizations and incarcerations than comparison participants. Relative to comparisons, psychiatric disorders with onsets at 21 years or older were not significantly elevated in probands. Probands without ongoing psychiatric disorders had worse social, but not occupational, functioning. CONCLUSIONS The multiple disadvantages predicted by childhood ADHD well into adulthood began in adolescence, without increased onsets of new disorders after 20 years of age. Findings highlight the importance of extended monitoring and treatment of children with ADHD.

ABSTRACT

CONTEXT: Volumetric studies have reported relatively decreased cortical thickness and gray matter volumes in adults with attention-deficit/hyperactivity disorder (ADHD) whose childhood status was retrospectively recalled. We present, to our knowledge, the first prospective study combining cortical thickness and voxel-based morphometry in adults diagnosed as having ADHD in childhood. OBJECTIVES: To test whether adults with combined-type childhood ADHD exhibit cortical thinning and decreased gray matter in regions hypothesized to be related to ADHD and to test whether anatomic differences are associated with a current ADHD diagnosis, including persistent vs remitting ADHD. DESIGN: Cross-sectional analysis embedded in a 33-year prospective follow-up at a mean age of 41.2 years. SETTING: Research outpatient center. PARTICIPANTS: We recruited probands with ADHD from a cohort of 207 white boys aged 6 to 12 years. Male comparison participants (n = 178) were free of ADHD in childhood. We obtained magnetic resonance images in 59 probands and 80 comparison participants (28.5% and 44.9% of the original samples, respectively). MAIN OUTCOME MEASURES: Whole-brain voxel-based morphometry and vertexwise cortical thickness analyses. RESULTS: The cortex was significantly thinner in ADHD probands than in comparison participants in the dorsal attentional network and limbic areas (false discovery rate < 0.05, corrected). In addition, gray matter was significantly decreased in probands in the right caudate, right thalamus, and bilateral cerebellar hemispheres. Probands with persistent ADHD (n = 17) did not differ significantly from those with remitting ADHD (n = 26) (false discovery rate < 0.05). At uncorrected P < .05, individuals with remitting ADHD had thicker cortex relative to those with persistent ADHD in the medial occipital cortex, insula, parahippocampus, and prefrontal regions. CONCLUSIONS: Anatomic gray matter reductions are observable in adults with childhood ADHD, regardless of the current diagnosis. The most affected regions underpin top-down control of attention and regulation of emotion and motivation. Exploratory analyses suggest that diagnostic remission may result from compensatory maturation of prefrontal, cerebellar, and thalamic circuitry.

ABSTRACT

OBJECTIVE: To investigate the relationship between ADHD symptoms and impairment among adults diagnosed as having ADHD in childhood (ages 6-12). METHOD: Clinicians blindly interviewed 121 White males; the mean age was 41 years across the sample. DSM-IV adult ADHD behaviors were systematically rated, and impairment resulting from symptoms was scored on a 5-point Likert-type scale. RESULTS: Correlations between degree of impairment and number of behaviors were high (r's = .83 to .85, p < .001). The impairment criterion had no effect on classifying any participants as having, or not having, adult ADHD. All participants who reported experiencing 5 or more inattention or hyperactive-impulsive behaviors as "often" or "very often" in adulthood were significantly impaired by their symptoms. CONCLUSIONS: Contrary to results reported in children, there was a strong relationship between number of ADHD symptoms and degree of impairment. However, for several reasons (discussed in the article), it should not be concluded that the impairment criterion is superfluous.

ABSTRACT

BACKGROUND: Similar patterns of vulnerability to carbon dioxide (CO(2)) inhalation have been reported in adults with panic disorder (PD) and children with separation anxiety disorder (SAD), suggesting a link between the adult and child conditions. This study examines the influence of familial risk for PD on CO(2) responses in children with SAD. We hypothesized that offspring with SAD of parents with PD would have distinct CO(2) responses. METHODS: Two hundred twelve 9- to 20-year-old offspring of parents with or without PD were exposed to maintained 5% CO(2) inhalation in the participants' homes. Anxiety symptoms, panic attacks, and respiratory physiology (respiratory frequency and tidal volume) were monitored during baseline and 15-min maintained CO(2) breathing. RESULTS: As hypothesized, significant offspring SAD x parent PD interactions were obtained for anxiety symptoms, respiratory frequency, tidal volume, and a panting index during CO(2) inhalation. Offspring with both SAD and parental PD exhibited more anxiety symptoms at termination of 5% CO(2) breathing than the other offspring groups and had the most extreme values on measures of respiratory physiology. CONCLUSIONS: Youth with both SAD and parental PD have respiratory responses to CO(2) similar to adult PD. They might be a subtype of SAD at particularly high risk for adult PD.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Animal studies have shown that age at stimulant exposure is positively related to later drug sensitivity. The purpose of this study was to examine whether age at initiation of stimulant treatment in children with attention deficit hyperactivity disorder (ADHD) is related to the subsequent development of substance use disorders. METHOD: The authors conducted a prospective longitudinal study of 176 methylphenidate-treated Caucasian male children (ages 6 to 12) with ADHD but without conduct disorder. The participants were followed up at late adolescence (mean age=18.4 years; retention rate=94%) and adulthood (mean age=25.3; retention rate=85%). One hundred seventy-eight comparison subjects also were included. All subjects were diagnosed by blinded clinicians. The Cox proportional hazards model included the following childhood predictor variables: age at initiation of methylphenidate treatment, total cumulative dose of methylphenidate, treatment duration, IQ, severity of hyperactivity, socioeconomic status, and lifetime parental psychopathology. Separate models tested for the following four lifetime outcomes: any substance use disorder, alcohol use disorder, non-alcohol substance use disorder, and stimulant use disorder. Other outcomes included antisocial personality, mood, and anxiety disorders. RESULTS: There was a significant positive relationship between age at treatment initiation and non-alcohol substance use disorder. None of the predictor variables accounted for this association. Post hoc analyses showed that the development of antisocial personality disorder explained the relationship between age at first methylphenidate treatment and later substance use disorder. Even when controlling for substance use disorder, age at stimulant treatment initiation was significantly and positively related to the later development of antisocial personality disorder. Age at first methylphenidate treatment was unrelated to mood and anxiety disorders. CONCLUSIONS: Early age at initiation of methylphenidate treatment in children with ADHD does not increase the risk for negative outcomes and may have beneficial long-term effects.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

There are limited data on the neurocognitive correlates of childhood anxiety disorders. The objective of this study was to examine whether visual and verbal memory deficits of nonemotional stimuli are (1) a shared feature of three common childhood anxiety disorders (social phobia, separation anxiety disorder, and generalized anxiety disorder) or whether these deficits are restricted to specific anxiety disorders, and (2) present in offspring who possess at least one of the following established risk factors for anxiety disorders, parental history of panic disorder (PD), or major depressive disorder (MDD). One hundred and sixty offspring, ages 9-20 years, were recruited from parents with lifetime diagnoses of PD, MDD, PD plus MDD, or neither illness. Different clinicians blindly administered semistructured diagnostic interviews to offspring and parents. Verbal and visual memory subtests of the Wide Range Assessment of Memory and Learning were administered to offspring. The results showed that offspring with ongoing social phobia demonstrated reduced visual but not verbal memory scores compared to those without social phobia when controlling for offspring IQ, separation anxiety disorder, and generalized anxiety disorder. No other offspring anxiety disorder predicted memory performance. Neither parental PD nor parental MDD was associated with offspring memory performance. These findings are relevant to understanding the phenomenology of childhood anxiety disorders and may provide insights into the neural circuits underlying these disorders.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: The aim of this study was to use data from a family study of anxiety disorders to examine the familial association between alcohol use disorders and panic disorder (PD), controlling for alcohol use disorders in the proband. METHOD: Data from a family study of anxiety disorders were used to compare rates of alcohol use disorders in the relatives of 3 proband groups (PD with lifetime alcohol use disorders, PD without lifetime alcohol use disorders, and not-ill controls). RESULTS: There was a significantly higher rate (12%) of alcohol use disorders among the relatives of PD probands compared with relatives of controls (5%), even in the absence of alcohol use disorders in the proband and after adjusting for differences in sociodemographic characteristics and lifetime drug use disorders (chi2 = 5.4; df = 1; P = .02). Anxiety symptoms were more frequent among the male relatives of panic probands who received an alcohol diagnosis, compared with those who did not have alcohol use disorders (10/25 vs 22/111; chi2 = 4.6; df = 1; P = .03). A similar pattern was found in women (8/11 vs 63/156; chi2 = 4.4; df = 1; P = .036). CONCLUSIONS: These findings suggest a familial association between PD and alcohol use disorders. Future studies with more refined alcohol diagnoses are needed to replicate and investigate the mechanism of this association.

ABSTRACT

BACKGROUND: This and the companion paper present two sequential family studies of obsessive-compulsive disorder (OCD) conducted by the same research group, but with different sampling and best-estimate procedures. In addition to providing further data on familial transmission of OCD, we used comparison of disparate findings (moderate, specific familial aggregation in this first study versus a stronger effect for other anxiety disorders than for OCD alone in the second) to examine possible effects of proband characteristics and informant data on outcome. METHOD: In this initial study we interviewed 179 first-degree relatives of 72 OCD probands and 112 relatives of 32 never mentally ill (NMI) controls. Informant data were obtained on an additional 126 relatives (total "combined" samples of 263 and 154 respectively). Analyses used best-estimate diagnoses made by consensus of two "blinded" senior clinicians who reviewed all diagnostic materials including proband informant data about relatives. RESULTS: Significantly higher risk for OCD but not other anxiety disorders was found in relatives of OCD probands compared to relatives of controls in both the directly interviewed and combined samples. There was no relationship between proband age at onset of OCD and strength of familial aggregation. CONCLUSIONS: These data indicate moderate familial aggregation of OCD, but do not support increased transmission by early onset probands, or a familial relationship between OCD and other anxiety disorders with the possible exception of generalized anxiety disorder.

ABSTRACT

BACKGROUND: Overall findings of our first direct interview family study of obsessive-compulsive disorder (OCD) indicated that OCD is familial. In this replication study, we carefully examined the role of informant data in ascertaining OCD in relatives. METHOD: We interviewed 112 relatives of 57 OCD patients and 115 relatives of 41 not ill controls predominantly by telephone. Additional analyses included a combined sample of relatives about whom any diagnostic information was available (228 OCD and 239 controls). To examine the contribution of proband information about relatives, we considered two sets of best-estimate diagnoses. First, we ascertained best-estimate diagnoses for relatives using information from direct interviews and from all informants except the proband. Then, we re-diagnosed relatives based on all available information, including reports from the proband about their relatives. RESULTS: When relative diagnoses were derived without the benefit of proband informant reports, no evidence of familial OCD transmission was found. When diagnoses were made including information from the proband about the relative, evidence of familial OCD was found, but only when the diagnostic threshold was lowered to include cases with probable OCD or OCD symptoms. Other diagnoses (generalized anxiety disorder, social phobia, drug use disorder) were also higher among OCD relatives. CONCLUSIONS: This second study provides less robust support for familial transmission of OCD. Evidence for familial transmission of OCD was found only when diagnoses were made using information from the affected proband about their relatives. Taken in context of past findings, our own inconsistent results suggest that OCD may be heterogeneous with regard to familial transmission. Also, more careful attention should be paid to the contribution of informant reports, especially from relatives affected by the same disorder.

ABSTRACT

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.
