    ABSTRACT: To make a dimensional assessment of personality in individuals with pathological anxiety, the Tridimensional Personality Questionnaire (TPQ) was administered to 32 patients with panic disorder (PD) and 49 patients with generalized anxiety disorder (GAD). The most striking findings were a substantially increased score on the harm avoidance dimension in both groups of patients, and a lack of significant differences between the TPQ scores in patients with PD and GAD. The former finding suggests that higher levels of harm avoidance may be common to (although not necessarily specific for) various types of anxiety disorders. The latter finding is in agreement with the findings that PD and GAD do not differ significantly with respect to the associated personality disorder diagnoses, which may further cast a doubt on the validity of the distinction between PD and GAD.

    ABSTRACT: An eighteen month follow-up of chronic nightmare sufferers treated with imagery rehearsal, a cognitive-behavioral method, demonstrated significant and clinically meaningful decreases in nightmare frequency. Sixty-eight percent of subjects decreased their nightmares below criteria for a “Chronic Nightmare Disorder”. Significant improvement was also noted for sleep quality and daytime anxiety. The findings support the theory that nightmares may be clinically conceptualized as a primary sleep disorder in some chronic sufferers.

    ABSTRACT: Fifty-eight chronic nightmare sufferers were randomly assigned to two groups: treatment (n = 39) and wait-list control (n = 19). Treated Ss were taught a cognitive-behavioral technique called imagery rehearsal in which they learned in a waking state to change a nightmare and then to visualize the new set of images. Subjects were assessed pre-treatment and 3 months followup for nightmare frequency, self-rated distress and subjective sleep quality. Compared to controls, the treatment group showed significant and clinically meaningful decreases in nightmares. Treated Ss decreased nightmares as measured in nights/week (mean = -2.0, SD = 1.7, P = 0.0001) and actual number of nightmares (mean = -4.2, SD = 4.5, P = 0.0001). Significant improvement in self-rated sleep quality occurred in those treated compared with controls (P = 0.004); and, reduction in nightmares was a significant predictor of improvement in sleep (r = 0.55, P = 0.0001). These preliminary results lend support to the theory that, for some chronic sufferers, nightmares may be conceptualized as a primary sleep disorder which can be effectively and inexpensively treated with cognitive-behavioral therapy.

    ABSTRACT: Groups of patients with principal diagnosis of panic disorder (n = 54) and generalized anxiety disorder (n = 49) were compared on the basis of their comorbidity with other mental disorders. The rates and patterns of comorbidity were similar, except for comorbid simple phobia and past drug abuse. This finding was interpreted as failing to support a notion that there is essential distinction between panic disorder and generalized anxiety disorder.

    ABSTRACT: In order to compare hypochondriacal phenomena in patients with generalized anxiety disorder (GAD) and panic disorder (PD), and in order to examine the relationship between worries about illness on one hand, and disease fears/phobias and hypochondriacal beliefs on the other, the authors administered the Illness Attitudes Scales to patients with both GAD and PD, and determined the spheres of worry in patients with GAD. Patients with GAD were significantly less hypochondriacal than PD patients. A specific relationship between GAD and hypochondriasis was not found because worries about illness, which characterize some GAD patients, were largely independent from disease fears/phobias and hypochondriacal beliefs, which are a hallmark of hypochondriasis.

    ABSTRACT: Nightmare frequency and self-rated distress were assessed retrospectively in two groups of chronic nightmare sufferers 30 months after treatment. In the initial phase, the image group (N = 9) learned a cognitive-behavioral technique (imagery rehearsal) for the treatment of nightmares. They were taught in one group session to: (1) record a nightmare; (2) change it (usually to something positive); and (3) rehearse the new images daily. The record group (N = 10) recorded nightmares during the first month only and learned imagery rehearsal subsequent to 3-month follow-up measurements. At 3 months and at 30 months, both groups had significantly fewer nightmares, but only the rehearsal group had less total distress. The results support the theory that nightmares are a primary sleep disorder rather than a symptom of an underlying psychiatric problem.

    ABSTRACT: Ages of onset and the sequence of appearance of panic disorder (PD) and comorbid conditions were determined in a sample of 54 patients with the principal DSM-III-R diagnosis of PD. The onset of PD was earlier in patients with moderate to severe agoraphobia (AG) than in panic patients without AG. Patients with alcohol abuse and drug abuse before the onset of PD also had a tendency to develop PD earlier, which suggests that these conditions might have specifically predisposed to PD. All comorbid disorders, except for major depression, were more likely to precede the onset of PD so that, more often than not, PD appeared as a chronologically secondary condition. However, it was found that only for primary substance abuse such a temporal relationship might denote etiologic relatedness to PD, because of the reduced temporal distance between the onset of primary substance abuse and secondary PD.

    ABSTRACT: We examined the onsets of comorbid psychiatric disorders in patients with panic disorder (PD) (N = 54). In 42 patients (77.8%), PD was preceded by another psychiatric condition (secondary PD group), while in 12 patients (22.2%), PD occurred first or was the only diagnosed mental disorder (primary PD group). Patients with primary and secondary PD did not differ with respect to demographic variables, mean ages of onset of PD, mean duration of PD, number of patients with a personality disorder, and number of patients with different DSM-III-R subtypes of PD. Except for the anger and sleep scales of the Hopkins Symptom Checklist 90, patients with primary PD had significantly less self-rated psychopathology; they also displayed less extensive phobic avoidance, and had a lower rate of current psychiatric comorbidity. These findings are discussed in light of the value of the concepts of comorbidity and primary/secondary dichotomy.

    ABSTRACT: The frequency of symptoms during panic attacks and anticipation of the panic consequences were compared in patients with the subtypes of panic disorder (PD). Patients with moderate and severe agoraphobic avoidance reported that they had experienced more symptoms than patients with an uncomplicated PD (without agoraphobia [AG]); they also experienced almost all of the symptoms more frequently, with the difference being significant for a quarter of the examined panic symptoms. Panic patients with moderate and severe AG were also significantly more concerned about the loss of control and social and physical consequences of panic attacks. Taken together, these findings suggest that the severity of panic attacks, defined as the number of panic symptoms, along with a variety of anticipatory fears about the consequences of the attacks may contribute to the development of AG in panic patients.

    ABSTRACT: Twenty subjects with chronic nightmares for 17.2 years mean duration were randomly divided into two groups: Rehearsal and Recording. At inception, subjects in both groups were instructed to write down their nightmares for one month. The Recording group received no other intervention. Rehearsal subjects received a single treatment group session teaching an imagery rehearsal technique to reduce nightmare frequency. At inception and three months follow-up, both groups were compared for nightmare frequency and for self-rated distress with scales (Symptom Checklist and Symptom Questionnaire) measuring anxiety, depression, hostility, somatization and total distress. Nightmare frequency decreased significantly in both groups: Rehearsal group-7.2 per month to 2.0 per month (72% reduction) (p < 0.006); Recording group-9.4 per month to 5.0 per month (47% reduction) (p < 0.02). There were no statistically significant differences in the nightmare frequency reductions between groups. All anxiety, depression, somatization, hostility and total distress scores decreased substantially in the Rehearsal group. Most changes were significant. Changes in the Recording group were inconsistent and not significant. Two brief case histories are presented.

    ABSTRACT: Diagnoses of comorbid disorders were determined in a sample of 54 patients with panic disorder as defined in DSM-III-R. The sample was divided into the following three groups: (1) uncomplicated panic disorder (PDU); (2) panic disorder with mild agoraphobia (PDM); and (3) panic disorder with moderate to severe agoraphobia (PDA). In comparison with patients with PDU, patients with PDA had higher comorbidity rates in general, received multiple comorbid diagnoses more frequently, had a higher prevalence of major depression, dysthymia, social phobia, generalized anxiety disorder, and obsessive-compulsive disorder, and scored higher on most measures of self-rated psychopathology. These findings support the notion that PDA may be a disorder essentially different from PDU.

    ABSTRACT: The purpose of this study was to examine the effects of one session of instructions on the frequency of chronic nightmares and on self-rated distress. Twenty-eight volunteers with chronic nightmares (mean duration = 19 years) were treated with either one session of desensitization with instructions on how to practice this treatment or with one session of instructions to change the nightmare and how to rehearse the new version. The authors administered four scales of the SCL-90 and the corresponding scales of the Symptom Questionnaire. At 7-month follow-up of 23 patients, there was a significant reduction in the frequency of nightmares and significant decreases in self-rated depression, anxiety, and hostility. There were no significant differences between the effects of the two types of treatment. In four patients, whose mean duration of nightmares was 23 years, the nightmares ceased. The results of this preliminary study suggests that the instructions given to the patients reduced the frequency of their chronic nightmares and decreased their self-rated distress.

    ABSTRACT: Four self-rating scales of hypochondriasis and the Symptom Checklist-90 were administered to 100 general practice (GP) patients and matched non-psychotic psychiatric out-patients. In a stepwise linear regression, self-rated somatic symptoms and anxiety predicted hypochondriacal fears and beliefs; self-rated depression did not appear as a predictor. There were differences between males and females and between psychiatric patients and GP patients in the associations of these constructs. These results varied in part with the scale of hypochondriasis used. Various scales of hypochondriasis appear to measure different features of the hypochondriasis syndrome. Fear of disease (disease phobia) was associated with anxiety, whereas a false belief of having a disease (disease conviction) was associated more with somatic symptoms.

    ABSTRACT: The purpose of this study was to examine correlates of hypochondriacal fears and beliefs in patients with panic disorder (PD) (n = 54). They were evaluated using the structured diagnostic interviews for axis I and axis II disorders (SCID-UP-R and SCID-II). They were administered the Illness Attitudes Scales (IAS) as a measure of hypochondriacal fears and beliefs, the Hopkins Symptom Checklist 90 (HSCL), and the Fear Questionnaire (FQ). One half of the patients rated themselves as having substantial hypochondriacal fears and beliefs. The sample was divided into groups of patients seeking predominantly treatment or relief from symptoms (treatment-oriented), and those who were searching for a cause of their illness (explanation-seeking): the latter had significantly more hypochondriacal concerns. Avoidant, histrionic, and borderline personalities were more common in the hypochondriacal group. The results of several analyses suggest that patients with PD who are also agoraphobic, fear physical disease more and have more false beliefs of having a disease than PD patients without agoraphobia.

    ABSTRACT: In order to examine the relationship of self-rated inhibited anger to somatization, the authors administered several self-rating scales, including the SCL-90 and a Likert scale pertaining to inhibited anger, to psychiatric patients and family practice patients of both sexes. In a linear stepwise regression, depression predicted inhibited anger in all four groups. Previous studies have reported an association of inhibited anger and somatization; the present study suggests that depression is the link between the two in the majority of patients. The relationship of inhibited anger to depression may have implications for psychotherapy.

    ABSTRACT: In order to examine the relationship of dyspnea to anxiety and depression, the authors rated dyspnea using several methods in 50 patients with chronic respiratory impairment. Anxiety and depression were measured by the Symptom Checklist-90 and the Symptom Questionnaire. Results varied with the method of assessing dyspnea. Physician-rated dyspnea was significantly associated with patients' self-ratings of breathlessness as well as with pulmonary function tests, but not with any of the self-rating scales of emotions. Self-rated breathlessness was significantly associated with self-rated depression. In multiple regression analyses, depression was predictive of breathlessness. When the sample was limited to patients with chronic obstructive pulmonary disease, the results remained the same. The patients were significantly more depressed and anxious than matched family practice patients. In the study of the complex relationship of dyspnea to physical and emotional factors, it is desirable to use more than one measure of dyspnea because the results depend in part on the method of assessment.

    ABSTRACT: To assess the severity of distress and of somatization in hypochondriasis, the authors administered several validated self-rating scales of depression, anxiety, somatic symptoms, and anger/hostility to 21 psychiatric outpatients with the DSM-III diagnosis of hypochondriasis and to matched groups of other nonpsychotic psychiatric patients, family practice patients, and employees. Anxiety and somatic symptoms were highest in hypochondriacal patients; depression and anger/hostility did not differ from those of other psychiatric patients but were higher than in the other groups. The findings do not support the theory that hypochondriasis is a defense against anxiety or that it is a masked depression or depressive equivalent. The findings are consistent with the view that the interaction of severe anxiety and severe somatic symptoms is a common feature of the psychopathology of hypochondriasis.

    ABSTRACT: The authors matched gynecologic patients with the abdominal pelvic pain syndrome (N = 41) with other gynecologic patients. They administered to both groups self-rating scales of anxiety, depression, anger-hostility, and somatization of the Hopkins Symptom Checklist and of the Symptom Questionnaire, a questionnaire about disruptions in early home life, and a questionnaire of recent stressful events. Patients with pain rated themselves on the average significantly more anxious, depressed, and hostile, and had more somatic symptoms than other patients; 56% of the patients with pain rated themselves within the normal ranges on all scales. There were no significant differences between the two groups in reports of disruptions of early home life and recent losses. The findings are consistent with the view that patients with the abdominal pelvic pain syndrome are psychologically a heterogeneous group; in many patients, depression and anxiety may be consequences of persistent pain.

    ABSTRACT: In order to explore attitudes and beliefs in patients with the pelvic pain syndrome, the authors matched gynaecological patients with this syndrome (N = 41) with other gynaecological patients. They administered the Illness Behavior Questionnaire and Illness Attitude Scales (that measure attitudes, fears and beliefs about illness) to both groups. In spite of thorough investigations, 18 patients (44%) with the pelvic pain syndrome believed that their physician had not diagnosed their illness correctly and feared that they had a serious disease. The findings appear to have implications for treatment.
