Velo-cardio-facial syndrome (VCFS) is a congenital malformation syndrome with variable phenotypic features that has been associated with chromosomal microdeletion 22q11.2. Psychiatric disorders have been reported to be highly prevalent in individuals with this syndrome, and the objective of this study was to assess the nature and extent of psychopathology among individuals with VCFS. We studied 20 children and adolescents with 22q11 deletions determined by fluorescence in situ hybridization (FISH). Control subjects were 11 nondeleted siblings who were the closest age match to the affected subjects. Both affected and control subjects were assessed using two standardized psychiatric research instruments. The results of this study confirmed the high rate of psychiatric disorders among VCFS subjects (60% of our subjects). Of the specific types of disorders, only mood disorders were significantly more common among VCFS subjects compared to sibling controls, with eight VCFS subjects having mood disorders compared with none of the control subjects (P<0.02). Three affected subjects had schizotypal traits comorbid with a mood disorder. In addition, disruptive behavior disorders were frequently diagnosed among VCFS subjects. Using a dimensional measure of psychopathology, significant differences between VCFS subjects and sibling controls were found on three scales: ADHD (P<0.02), separation anxiety (P<0.02), and depression (P<0.01). VCFS subjects were achieving significantly less well academically and requiring significantly more special educational assistance than sibling controls. Follow-up data were available on two subjects, both of whom had been diagnosed with schizophrenia. Further research on psychopathology in VCFS may provide a model of how a specific genetic defect can lead to the development of psychiatric disorders.

According to attachment theorists, affect regulation and quality of attachment are closely linked. As a personality trait associated with deficits in the cognitive processing and regulation of affects, alexithymia has been hypothesized to correlate with insecure attachment. To test this hypothesis, we studied the relationships between alexithymia, adult attachment style, and retrospective memories of separation anxiety symptoms during childhood in 100 young men with clinically significant mood symptoms. The most common DSM-IV diagnosis (N = 72) was adjustment disorder with depressed mood, with anxiety, or with mixed anxiety and depressed mood. Each participant completed the Twenty-Item Toronto Alexithymia Scale (TAS-20), the Beck Depression Inventory (BDI), the state form of the State-Trait Anxiety Index (STAI), the Attachment Style Questionnaire (ASQ), the Relationship Questionnaire (RQ), and the Separation Anxiety Symptom Inventory (SASI). Alexithymic traits were more pronounced in those participants who had patterns of insecure attachment and who reported more severe symptoms of separation anxiety during childhood, independently of the severity of their current anxiety and depressive symptoms. Among the subgroup of participants with insecure attachment styles, those with preoccupied or fearful patterns had a higher prevalence of alexithymia (65% and 73%, respectively) than those with a dismissing pattern (36%). These data suggest a role for early developmental factors in the etiology of alexithymia

Used multiple methods and measures (i.e., youth report, psychiatric interviews, psychophysiological assessment) to investigate the emotional and behavioral impacts of exposure to community violence. Participants were 185 inner-city high school students (M age = 15.4 years; 42% female; 90% African American). Youth with high levels of community violence exposure reported more fears, anxiety, internalizing behavior, and negative life experiences than those with low exposure. No depression or externalizing behavior differences were observed. In a psychophysiological assessment in which adolescents watched a montage of media violence, youth exposed to high levels of community violence had lower baseline heart rates than those with low exposure. There were no between-group differences in physiologic reactivity. Regression analyses revealed that community violence exposure predicted posttraumatic stress and separation anxiety symptoms. The results suggest a significant link between community violence exposure and anxiety symptomatology. Clinical implications are discussed.

Examined the relation between early anxiety symptomatology (generalized and separation) and initiation of alcohol use 4 years later in an epidemiological sample of 936 children (45% girls), assessed at ages 9, 11, and 13, while controlling for the effects of depression. Although earlier overall anxiety symptomatology was unrelated to later onset of drinking, children with early symptoms of generalized anxiety were found to be at increased risk for initiation of alcohol use, whereas children with early symptoms of separation anxiety were at decreased risk. The magnitude of these relations was equally strong for boys and girls. In addition, early depressive symptomatology was associated with increased risk for initiation of alcohol use in adolescence. Results indicate that it is important to consider specific dimensions of anxiety symptomatology when attempting to identify those individuals at risk for early initiation of alcohol use.

Through electronic mail, we surveyed members of an internet support group for emetophobia (fear of vomiting). Respondents were 50 women and 6 men with a mean age of 31 years. Results suggest that, for this sample, emetophobia is a disorder of early onset and chronic course, with highly persistent and intrusive symptoms. Emetophobia is implicated in social, home-marital, and occupational impairment and it causes significant constriction of leisure activities. Nearly half of women avoided or delayed becoming pregnant. About three quarters of respondents have eating rituals or significantly limit the foods they eat. Respondents describe other problems such as depression, panic attacks, social anxiety, compulsions, and frequent history of childhood separation anxiety.

Attention-deficit/hyperactivity disorder (ADHD) is a phenotypically heterogeneous and highly heritable syndrome. which commonly co-occurs with other psychiatry disorders. To assess the role of genetic influences in ADHD, we used latent class analysis (LCA) to identify subtypes of ADHD taking into account its comorbidity with separation anxiety, oppositional defiant disorder (ODD), and three major depression symptoms. A structured interview was used to collect diagnostic data from a population sample of 2,904 adolescent female twins and their parents. LCA was applied to ADHD. separation anxiety. ODD symptom profiles obtained from the twins' parents, and major depression symptom profiles obtained from the twins' self-report. Odds ratios were used to test for familiality of class membership by examining the effect of zygosity on twin concordance within and between latent classes. Structural equation modeling was used to compute heritabilities for latent class membership. LCA revealed three ADHD categories of clinical interest: an inattentive subtype without comorbidity, a second inattentive subtype with increased number of ODD symptoms. and a combined inattentive/hyperactive-impulsive type with elevated levels of ODD, separation anxiety, and depressive symptoms. LCA also distinguished an ODD class and a separation anxiety class, each without increased levels of other comorbid symptoms; a second ODD class co-occurring with increased separation anxiety and depression symptoms; and a pure depression class. Odds ratios for MZ contrasted with DZ twin concordance for individual latent class membership ranged from 2.5 to 19.4. Overall, 66% of MZ pairs, but only 36% of DZ pairs, were assigned to the same latent class, consistent with a genetic hypothesis for latent class membership. Individual class membership was shown to have high heritability ranging from .34-.85. The pattern of latent classes suggested that in the general female adolescent population, there are three highly heritable ADHD subtypes, two of which are comorbid with other disorders. These classes were consistent with a genetic hypothesis for ADHD, with each class potentially reflecting a unique genetic subtype.

The present study investigated the links between aspects of the self (self-evaluations, self-worth), attachment representations and behavioral functioning in 8-year-old children. Self-evaluations were assessed with an interview in which children described themselves and discussed positive and negative aspects of the self; self-worth was assessed using a subscale from the Dimensions of Depression Inventory. Attachment representations were assessed using the Separation Anxiety Test. Mothers and teachers reported on children's behavior problems, school adaptation and peer competence. Following previous work with 5- (Verschueren & Marcoen, 1999; Verschueren, Marcoen, & Schoefs, 1996) and 6-year-olds (Cassidy, 1988), we predicted that aspects of the self would be positively associated with attachment security and behavioral adaptation. These predictions were confirmed. A rating of the child's ease of access to self-evaluations (EASE) during the interview was related to emotional security and coping responses during the Separation Anxiety Test. Children with greater ease of access to self-evaluations also had fewer internalizing and total behavior problems, according to both mothers and teachers, and their teachers reported more positive school adaptation, peer competence and egoresiliency.

The purpose of this study was to investigate parenting received in childhood and early separation anxiety experiences in young male soldiers with adjustment disorder. Fifty-four conscripts suffering from adjustment disorder completed the following questionnaires: the Symptom Checklist-90-Revised (SCL-90-R), the Measurement of Parental Style (MOPS), and the Separation Anxiety Symptom Inventory (SASI). Seventy-eight conscripts, matched for age and education, were used as a control sample. The research showed that compared with the controls, patients had significantly increased scores on the SCL-90-R (p < 0.001), the SASI (p < 0.03), and the father's and mother's MOPS Abuse subscale (p < 0.001). The father's MOPS Abuse score, the mother's MOPS Overcontrol score, and the SASI score were also significantly correlated with the SCL-90-R score (p < 0.01). Finally, a patient's separation anxiety can be predicted from the mother's overcontrol behavior, and the severity of the disorder can be predicted from the father's abuse behavior. These findings are in agreement with previous findings in patients with depression and anxiety disorders.

The heritability and prevalence of the gender identity disorder (GID) was examined, as well as its comorbidity with separation anxiety and depression, in a nonretrospective study of child and adolescent twins. The parents of 314 twins (ages 4-17 years; 96 monozygotic pairs [MZ] and 61 dizygotic [DZ] pairs) completed the Coolidge Personality and Neuropsychological Inventory (CPNI) containing a six-item DSM-IV-based GID scale. Prevalence of clinically significant GID symptomatology in the twin sample was estimated to be 2.3%. Univariate model fitting analyses were conducted using an ordinal transformation of the GID scale. The model that best described the data included a significant additive genetic component accounting for 62% of the variance and a nonshared environmental component accounting for the remaining 38% of the variance. Results suggested no heterogeneity in the parameter estimates resulting from age. The correlation between GID and depression was modest, but significant (r = .20; P < .05), whereas the correlation between GID and separation anxiety was nonsignificant (P > .05). Overall, the results support the hypothesis that there is a strong heritable component to GID. The findings may also imply that gender identity may be much less a matter of choice and much more a matter of biology.

The psychometric properties of the Spence Children's Anxiety Scale (SCAS) were examined with 875 adolescents aged 13 and 14 years. This self-report measure was designed to evaluate symptoms relating to separation anxiety, social phobia, obsessive-compulsive disorder, panic-agoraphobia, generalized anxiety, and fears of physical injury. Results of confirmatory and exploratory factor analyses supported six factors consistent with the hypothesized subtypes of anxiety. There was support also for a model in which the first-order factors loaded significantly on a single second-order factor of anxiety in general. The internal consistency of the total score and sub-scales was high, and 12-week test-retest reliability was satisfactory. The SCAS correlated strongly with a frequently used child self-report measure of anxiety and significantly, albeit at a lower level, with a measure of depression.
