The comprehensive assessment of defense style: measuring defense mechanisms in children and adolescents.

This study introduces the Comprehensive Assessment of Defense Style (CADS), a new method to assess descriptively the defensive behavior of children and adolescents. Parents of 124 children and adolescents referred to a mental health clinic, of 104 nontreated children, and of 15 children whose fathers were treated for posttraumatic stress disorder completed the CADS. Factor analysis of 28 defenses yielded one mature factor, one immature factor of defenses expressed in relations with the environment (other-oriented), and one of defenses expressed in relations with the self (self-oriented). The CADS significantly discriminated between patients and nonpatients. Psychiatric patients used more immature and fewer mature defenses than control subjects, and adolescents used more mature and fewer other-oriented defenses than children. Girls used more mature and fewer other-oriented defenses than boys. The reliability and validity data of the CADS are encouraging. The three defense factors may be implemented for diagnostic and clinical purposes as well as for screening for psychopathology risk in untreated populations.

Validation of the Comprehensive Assessment of Defense Style (CADS): mothers' and children's responses to the stresses of missile attacks.

This study furthers the validation of the Comprehensive Assessment of Defense Style (CADS) as a measure of children's defensive behavior. Participants were 81 mothers who assessed the defense style (CADS) of their 8- to 10-year-old children, as well as their own defense style and level of object relations. Five years earlier, the mothers had rated their children's symptom level and personality after the missile attacks during the Gulf War. The original factor structure of the CADS was replicated for the most part. Self-oriented and other-oriented defenses were related to the children's early personality and symptomatic reaction, as well as to their mother's defense style and level of object relations. The CADS factors correlated with the defenses of the Defense Mechanisms Manual. The results provide further validation of the CADS and suggest possible areas of implementation, such as longitudinal examination of defenses, psychopathology screening, and therapeutic improvement.

Mothers' functioning and children's symptoms 5 years after a SCUD missile attack.

OBJECTIVE: The authors assessed the long-term consequences of the SCUD missile attack in Israel on children as a function of their mothers' psychological functioning, family cohesion, and the event itself. METHOD: Five years after the Gulf War, the authors assessed the internalizing, externalizing, stress, and posttraumatic symptoms of 81 children aged 8-10 years whose homes were damaged in the SCUD missile attack, as well as general and posttraumatic symptoms, defensive style, and object relations in their mothers. RESULTS: There was a significant decrease in severity in most symptom domains and an increase in avoidant symptoms in the children. Greater severity of symptoms was associated with being displaced, living in a family with inadequate cohesion, and having a mother with poor psychological functioning. The association between the symptoms of children and mothers was stronger among the younger children. Posttraumatic symptoms increased in one-third of the children and decreased in one-third over the last 30 months of the study. Severe posttraumatic symptoms were reported in 8% of the children. CONCLUSIONS: Despite a continuous decrease in symptom severity, risk factors identified shortly after the Gulf War continued to exert their influence on children 5 years after the traumatic exposure.

Case series: brief parent-child group therapy for childhood anxiety disorders using a manual-based cognitive-behavioral technique.

OBJECTIVE: To report on a brief parent-child group therapy program for children with anxiety disorders. METHOD: Twenty-four children with an anxiety disorder and their parents participated in a 10-session treatment. Children were evaluated at pretreatment (T1), posttreatment (T2), 12-month follow-up (T3), and 36-month follow-up (T4). Ten children were also assessed on entering a waiting period (T0). RESULTS: There were no significant symptomatic changes between T0 and T1. Anxiety symptoms decreased significantly during the treatment and follow-up periods. Depressive symptoms changed only during the follow-up period. The percentage of children with no current anxiety disorder was 71% at T2 and 91% at T4. Children of mothers with an anxiety disorder improved more than children of nonanxious mothers, whereas the anxiety level of anxious mothers remained stable. CONCLUSIONS: Brief parent-child group psychotherapy may serve as a time-limited, cost-effective, and efficient intervention.

The mother-child dyad facing trauma: a developmental outlook.

The effects of trauma in children are amply documented. This paper investigated the relationship between children's age and posttraumatic clusters of symptoms 30 months after the end of the Gulf War and the mother's reaction to the trauma 6 and 30 months after the war. Fifty-one children aged 6 to 8 years (3 to 5 years during the war) and their mothers were interviewed. Results showed no age differences in the various posttraumatic symptoms of the children. Correlations between the children's posttraumatic symptoms and both the general and the specific posttraumatic symptoms of their mothers were positive and significant in the 6-year-olds, positive and nonsignificant in the 7-year-olds, and nonsignificant and mostly negative in the 8-year-olds. These findings may reflect the developmental changes that render the older child more autonomous and the younger child rigidly attached to the mother after a traumatic event.

Image control and posttraumatic symptoms in children following SCUD missile attacks.

Based on previous studies reporting an association between high image control and low posttraumatic symptoms in adults exposed to a traumatic event, this study explored whether a high capacity for image control by children may serve as protective factor against the long-term effect of trauma. The sample consisted of 39 children displaced due to the destruction of their homes after the missile attack on Tel-Aviv during the Gulf War. Analysis confirmed the hypothesis that low scores on the Test of Visual Image Control were associated with specific posttraumatic symptoms but not with general ones.

Image vividness as a psychophysiological regulator in Posttraumatic Stress Disorder.

This study examined the relationship between image vividness and psychophysiological responses to trauma-related stimuli in participants with Posttraumatic Stress Disorder (PTSD). An auditory stimulus related to a shared trauma was presented to participants with and without PTSD and physiological parameters (heart rate and blood pressure) were measured concurrently. A negative correlation was noted in the PTSD group between image vividness and the level of physiological response. When the PTSD group was divided into high and low vividness, the physiological response was higher than that of the non-PTSD controls only when image vividness was low. The results are discussed in the context of Lang' s theoretical model, emphasizing the role of image vividness in the mediation and regulation of psychophysiology.

Ondansetron treatment in patients with Tourette's syndrome.

Ondansetron, a selective 5-HT3 antagonist, may lower mesolimbic dopaminergic hyperactivity. The present open-label pilot study evaluated the effect of ondansetron in Tourette's syndrome. Six Tourette's syndrome men aged 14-48 years resistant to haloperidol participated in the study. Assessments included the Yale Global Tic Severity Scale (YGTSS), Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and Tourette's syndrome-Clinical Global Impression (TS-CGI) scale. The maximal ondansetron dosage (8-16 mg per day) was given for 3 weeks. Ondansetron treatment was associated with a significant decrease in the severity of tics. Two patients showed a definite response (score improvement of 40% or more), and two showed a probable response (> 25%). Two patients did not improve. Side-effects were transient and included abdominal pain (n = 5) and constipation (n = 2). Ondansetron may possess anti-tic effects in some Tourette's syndrome patients.

Image control and symptom expression in posttraumatic stress disorder.

Despite the devastating impact of affective dysregulation in posttraumatic stress disorder (PTSD), there has been little research on how trauma relates to affect regulation. This study examines the relationship between the cognitive capacity to control mental images and symptoms of individuals with (N = 23) and without (N = 23) PTSD after exposure to SCUD missile attacks during the Gulf War. The capacity to control mental images, symptoms of posttrauma, anxiety, and anger were assessed. PTSD subjects with a high image control reported a higher capacity to control anger, lower levels of anger state and expression, and lower levels of intrusive symptoms compared with PTSD subjects with low image control. In individuals without PTSD, results show that the better the image control, the lower the control of anger and the higher the expression of anger. Image control seems to play different functions in the emotional regulation of normal subjects (facilitatory) and PTSD patients (protective).

Image control from childhood to adolescence.

Despite the recognized importance of imagery use by children as well as the developmental relevance for maturity and health of imagery properties such as vividness and control, only a few studies have investigated imagery of children. The aim of the present study was to examine the development of control of mental images in a sample of boys and girls aged 7 to 17 years. Children were assessed on two aspects of mental imagery, vividness and control, and teachers were asked to rate the children's intellectual and socioemotional performance. Analysis showed that the capacity for image control increased in adolescence and that children characterized by vivid and uncontrolled imagery received the lowest ratings from teachers, whereas those with nonvivid and controlled imagery received the highest ratings. The implications of these results were discussed in relation to normal and abnormal development as well as suggestions for research.

The function of image control in the psychophysiology of posttraumatic stress disorder.

The physiological response to trauma-related stimuli of up to one third of participants with posttraumatic stress disorder (PTSD) cannot be discriminated from that of controls. Psychophysiological measures (heart rate and blood pressure) of 22 PTSD and 23 control civilian participants, all exposed to missile attacks during the Gulf War, were recorded while listening to five scripts. The physiological response of PTSD subjects with high image control (IC) was lower than that of PTSD participants with low IC and similar to that of non-PTSD subjects. The physiological response poorly discriminated high IC PTSD participants from controls, but was successful in discriminating low IC PTSD subjects from controls with 91% specificity and 92% sensitivity. Image control is proposed as a function influencing physiological response in PTSD.

Lack of effect of methylphenidate on serum growth hormone (GH), GH-binding protein, and insulin-like growth factor I.

The aim of this study was to assess the growth hormone (GH) axis in methylphenidate (MPH)-treated and untreated boys with attention-deficit and hyperactivity disorder (ADHD), by evaluating serum GH, GH-binding protein (GHBP) activity, and insulin-like growth factor I (IGF-I) levels as compared to age-matched normal controls. Blood samples were taken from 42 boys (aged 6-16 years) diagnosed as having ADHD according to DSM-III-R criteria and confirmed by using the Schedule for Affective Disorder and Schizophrenia for school-age children (K[Kiddle]-SADS). A total of 21 patients were treated with MPH (5-20 mg/day; 0.15-0.77 mg/kg/day), on a drug holiday protocol, for 1-36 months, and 21 were drug naive. A total of 46 age-matched normal boys at height and weight within normal range served as controls. No significant differences were detected between the MPH-treated ADHD children, the untreated ADHD children, and the control children on fasting serum GH levels, GHBP activity, or IGF-I levels. Active treatment with MPH, in ADHD children on a drug holiday protocol, does not cause changes in GH axis as manifested by normal values of GH, GHBP, and IGF-I.

Israeli preschool children under Scuds: a 30-month follow-up.

OBJECTIVE: Longitudinal studies of children exposed to traumatic events show contrasting findings regarding their symptomatic change over time. The present study reports on a 30-month follow-up of preschool children and their mothers who had been exposed to Scud missile attacks. METHOD: Families displaced during the Gulf War after their homes had been damaged by the missile attack and a control group whose homes remained intact were interviewed about posttraumatic and general symptomatology, the mothers' capacity to control images, and the children's adaptive behavior. RESULTS: Stress symptoms decreased in the displaced children but not in their mothers. Both reported more posttraumatic symptoms than did the control group. No differences in the children's adaptive behavior were observed. Posttraumatic symptoms of the displaced children correlated with the mothers' avoidant symptoms. The mothers' avoidant symptoms at follow-up were statistically explained by the mothers' symptoms during the war and their capacity for image control, the duration of displacement, and the cohesion of the family. CONCLUSIONS: The maternal stress-buffering capacity constitutes a central element in children's protective matrix and is crucial in minimizing long-term internal suffering of traumatized preschool children.

Platelet imipramine binding in patients with posttraumatic stress disorder before and after phenelzine treatment.

Posttraumatic stress disorder (PTSD) is frequently associated with major depressive disorder, and antidepressants have been reported to ameliorate PTSD symptoms in some patients. The present study assessed the number and affinity of platelet imipramine binding sites, as a marker of the serotonin transporter complex, in PTSD male patients (n = 10) before and after phenelzine treatment (30-60 mg/day, for 4 weeks) as well as in comparison to healthy controls (n = 10). In our sample, there was no evidence of a significant difference in the characteristics (Bmax and Kd) of platelet [3H]imipramine binding between the PTSD patients and the controls and within PTSD patients before and after phenelzine treatment. Moreover, no beneficial effect of phenelzine was detected in the patients (as assessed by PTSD, anxiety, and depression scales).

Israeli preschoolers under Scud missile attacks. A developmental perspective on risk-modifying factors.

BACKGROUND: The devastating effects of traumatic events on children are modulated by risk and protective factors. This study examines the differential effects of traumatic displacement of preschool children and their families following Scud missile attacks on Israel during the Persian Gulf War. METHODS: Three groups participated in the study: families displaced after their houses were damaged, undisplaced families from the same neighborhood (without home damage), and families from a distant city that was threatened but not directly attacked. Data concerning the traumatic event, the child (personality, internalizing, externalizing, and stress symptoms), the mother (Symptom Checklist-90-Revised), and the family (Family Adaptability and Cohesion Evaluation Scales) were gathered 6 months after the end of the war. RESULTS: Displaced children and mothers showed higher externalizing and stress symptom levels compared with undisplaced and threatened subjects. Destruction of the house and displacement, but not mere distance from the missile impact, explained symptomatic behavior. Inadequate family cohesion predicted symptomatic reaction for 3- and 4-year-old children but not for older ones. CONCLUSION: Both human and nonhuman factors contribute to the preschool child's adaptive mechanisms that regulate environmental stressful stimuli. These risk-modifying factors become more autonomous of caretakers with increasing age.

Altered platelet peripheral-type benzodiazepine receptor in posttraumatic stress disorder.

Peripheral-type benzodiazephine receptors (PBR) are involved in steroidogenesis and are sensitive to stress. Reduced platelet PBR density has been demonstrated in generalized anxiety disorder (GAD), but not in obsessive-compulsive disorder (OCD). We extended this observation to another anxiety disorder, namely, posttraumatic stress disorder (PTSD). Eighteen post-Persian Gulf War PTSD patients and 17 age- and sex-matched controls were included in the study. All subjects were evaluated using the Structured Clinical Interview for DSM-III-R-Patient Version. The severity of symptoms was assessed using the DSM-III-R scale for PTSD, the Impact of Event Scale, the Beck Depression Inventory, and the State-Trait Anxiety Inventory. [3H]PK 11195 was used to label platelet PBR. All psychological parameters (except trait anxiety) were higher in PTSD patients compared to controls. Decreased platelet PBR density (-62%; p < .001) was observed in the PTSD patients compared to controls. The reduction in PBR observed in PTSD patients was in accordance with the findings in GAD patients, but differed from those obtained in OCD patients. It is possible that the receptoral downregulation is an adaptive response aimed at preventing chronic overproduction of glucocorticoids in hyperarousal states.

T cell subsets in obsessive-compulsive disorder.

Stress can produce immunosuppression leading to increased susceptibility to infection, tumor growth or autoimmune disease. It has been recently noted, however, that certain kinds of stress need not increase the risk of immune pathology. The present study looked for immune pathology in an anxiety-related disorder. Acute exacerbation of obsessive-compulsive disorder (OCD), an anxiety spectrum disorder, served as a model for stress. Seven OCD subjects in acute exacerbation, and 9 healthy age-matched control subjects participated in the study. T cell subsets were determined at baseline in both OCD and control groups, and after 6 weeks on clomipramine in the OCD group. No statistically significant changes in lymphocyte subsets were found between the control and the untreated patient groups. Likewise, no statistically significant changes were found in patients before and after treatment. The negative findings of the present study supports the view that stress need not compromise immunologic function. Various aspects of stress, which may turn the immune system vulnerable, are discussed as well.
