Convergent validity of measures of cognitive distortions, impulsivity, and time perspective with pathological gambling.

The present study investigated the convergent validity of the Gamblers' Beliefs Questionnaire (GBQ), Gambling Passion Scale (GPS), Eysenck Impulsivity Questionnaire (EIQ), and Stanford Time Perception Inventory (STPI) in reference to pathological gambling. The authors recruited 105 undergraduates representing categories of pathological gamblers, potential pathological gamblers, and nonpathological gamblers and administered the measures under neutral conditions. Both subscales of the GBQ and GPS and the Impulsivity subscale of the EIQ exhibited strong convergent validity, whereas the STPI showed weaker correspondence with symptoms of pathological gambling. Applications and limitations of these findings are discussed.

Clinical characteristics and associated psychopathology of 22 patients with kleptomania.

The current study was constructed to detail the demographic, phenomenological, family history, and treatment response data in a group of patients with kleptomania. Twenty-two subjects, drawn from an outpatient population, with uncontrollable urges to steal completed both a semistructured interview that focused on stealing behavior and the Structured Clinical Interview for DSM-IV (SCID). Fourteen women and eight men reported an average age of onset of 16 years and an average symptom duration of 21 years. Sixteen patients (73%) reported particular triggers for their urges to steal. Seventeen subjects (77.3%) qualified for a lifetime axis I diagnosis and 9 (40.9%) qualified for a current axis I disorder other than kleptomania. These patients reported severe symptoms, with 15 subjects (68%) reporting intense shame or guilt following the thefts. We conclude that kleptomania is a distressing and disabling disorder associated with high rates of psychiatric comorbidity.

[Stealing in anorexia nervosa and bulimia nervosa].

Only recently stealing behaviour has been noticed as a symptom of anorexia nervosa and bulimia nervosa. Reviewing our sample of 63 patients we discuss the incidence and motivation of kleptomania. In 24% of our patients stealing behaviour was reported which is a definitely high rate compared to literature. Among the intentions for stealing behaviour we found: Stealing as conversion of revenge, self-assertiveness compensation of binge-eating or stealing as achievement. The differential motivation of stealing should be considered in legal consequences.

Outcome and comorbidity in first- compared with multiple-episode mania.

The aim of this study was to examine the outcome and comorbidity of patients with bipolar disorder presenting with first-episode as compared with multiple-episode mania. Based on studies from the prepharmacological era and the sensitization model of bipolar disorder, we hypothesized that compared with multiple-episode mania, first-episode mania would be associated with better outcome, milder severity, and less psychiatric comorbidity. Seventy-one hospitalized patients, age 12 years and older and meeting DSM-III-R criteria for bipolar disorder, were recruited over a 1-year period. Thirty-four (48%) first-episode and 37 (56%) multiple-episode patients were compared regarding demographics, phenomenology, comorbidity, family history, and short-term course. Compared with multiple-episode mania, first-episode mania was associated with significantly shorter hospitalization and a higher rate of comorbid impulse control disorders. These data provide indirect support for the sensitization model of bipolar disorder.

Comorbidity of eating disorders with bipolar disorder and treatment implications.

OBJECTIVES: To review the scientific evidence examining the comorbidity among eating disorders and bipolar disorder (BD). METHODS: We reviewed all published English-language studies addressing the comorbidity of anorexia nervosa, bulimia, bulimia nervosa, and binge eating disorder in patients with BD and studies of comorbidity of BD in patients with eating disorders. In addition, we discuss the pharmacologic treatment implications from reviewed studies of agents used in BD and eating disorders. RESULTS: Community and clinical population studies of the lifetime prevalence rates of eating disorders in patients with BD, and of BD in patients with eating disorders, particularly when subthreshold and spectrum manifestations of these disorders are included, indicate high rates of comorbidity among these illnesses. CONCLUSIONS: Pharmacologic treatment approaches to patients with BD and a co-occurring eating disorder require examination of the possible adverse effects of the treatment of each syndrome on the other and attempts to manage both syndromes with agents that might be beneficial to both.

Pathological gambling among cocaine-dependent outpatients.

OBJECTIVE: The authors investigated the occurrence of pathological gambling among cocaine-dependent outpatients, its influence on short-term outcome of treatment, and comparative characteristics of patients with and without pathological gambling. METHOD: The subjects were 313 cocaine-dependent (200 also opiate-dependent) outpatients in clinical trials of medication for cocaine dependence. Pathological gambling (DSM-III-R criteria) was assessed with the Diagnostic Interview Schedule, and sociodemographic and socioeconomic characteristics were determined with the Addiction Severity Index. Outcome was defined as time in treatment (proportion of maximum scheduled time) and proportion of cocaine-positive urine samples during treatment. RESULTS: Pathological gambling had a lifetime occurrence rate of 8.0% and a current (past month) occurrence of 3.8%. Onset preceded the onset of cocaine dependence in 72.0% of the patients (and preceded onset of opiate dependence in 44.4%). Patients with pathological gambling (lifetime or current) did not differ significantly from other patients in length of treatment or proportion of cocaine-positive urine samples. Those with lifetime pathological gambling were significantly more likely to have tobacco dependence (84.0% versus 61.1%) and antisocial personality disorder (56.0% versus 19.8%), to be unemployed (84.0% versus 49.3%), to have recently engaged in illegal activity for profit (64.0% versus 38.5%), and to have been incarcerated (62.5% versus 33.9%). CONCLUSIONS: Pathological gambling is substantially more prevalent among cocaine-dependent outpatients than in the general population. Patients with pathological gambling differ from other cocaine-dependent outpatients in some sociodemographic characteristics but not in short-term outcome of treatment for cocaine dependence.

Psychopathology and comorbidity of psychiatric disorders in patients with kleptomania.

OBJECTIVE: This study compared patients with kleptomania, patients with alcohol abuse or dependence, and psychiatric patients without impulse-control disorders or substance-related disorders on several key psychopathological dimensions. In addition, the comorbidity of kleptomania with other psychiatric disorders was examined. METHOD: Eleven patients with kleptomania recruited over a cumulative 2-year period and 60 patients with alcohol abuse or dependence and 29 psychiatric comparison patients recruited over a consecutive 6-month period participated in structured clinical interviews to determine the presence of impulse-control and substance-related disorders and of other psychiatric disorders that were comorbid with kleptomania. Psychopathological dimensions were measured with the Barratt Impulsiveness Scale, the Sensation Seeking Scale, the Montgomery-Asberg Depression Rating Scale, and the anxiety and depression subscales of the Hospital Anxiety and Depression Scale. RESULTS: Significant group effects were found for the Barratt Impulsiveness Scale total and cognitive impulsivity scores, with the patients with kleptomania having higher impulsivity scores than the other groups. Significant group differences were found on the Sensation Seeking Scale total and disinhibition scores. No significant group effects were found for the mood and anxiety measures. Patients with kleptomania had high rates of comorbid psychiatric disorders, particularly mood disorders, other impulse-control disorders, and substance abuse or dependence (mainly nicotine dependence). CONCLUSIONS: Kleptomania presented a specific psychopathological profile that distinguished patients with this disorder from patients with alcohol abuse or dependence and other psychiatric comparison patients. Impulsivity was the major psychopathological feature of kleptomania. A link between kleptomania and affective disorder was supported by the high rate of comorbid affective disorders in patients with kleptomania and a specific pattern of variation in the two conditions over time. Further prospective studies are needed to confirm this pattern. Because kleptomania is characterized by a low rate of comorbid substance-related disorders other than nicotine dependence and by severe psychopathology, it could be an appropriate disorder in which to study the information processes and psychobiology underlying impulsivity.

The neural correlates of cue-induced craving in cocaine-dependent women.

OBJECTIVE: Drug use reminders are associated with localized changes in brain activity related to intense drug wanting or craving in cocaine-dependent men. While cocaine dependence is prevalent and disabling in women, and certain clinically relevant sex differences exist, there is an absence of knowledge related to the neural correlates of cocaine craving in cocaine-dependent women. METHOD: The differential neural response to imagery depicting cocaine use and neutral imagery was defined by using [15O]H2O positron emission tomography (PET) imaging in eight cocaine-dependent women. Results were compared with a matched group of eight cocaine-dependent men. RESULTS: Cocaine-related imagery was associated with relative increases in cocaine craving and increases in regional cerebral blood flow in the superior temporal gyrus, dorsal anterior and posterior cingulate cortex, nucleus accumbens area, and the central sulcus. Compared with the results of an identical PET study in matched cocaine-dependent men, conditioned cocaine craving in women was associated with less activation of the amygdala, insula, orbitofrontal cortex, and ventral cingulate cortex and greater activation of the central sulcus and widely distributed frontal cortical areas. CONCLUSIONS: These findings suggest the presence of sex differences in the functional anatomy of cue-induced cocaine craving associated with drug dependence. Such differences may reflect sex differences in conditioned associations to cocaine use, in affective and other corollaries of cocaine craving, or in their volitional regulation and may underlie apparent sex differences in the effects of cocaine abstinence and the expectations of treatment outcome. Some support for the need for sex-specific strategies for treatment of cocaine dependence is also furnished by the findings of this study.

Treating impulsivity, irritability, and aggression of antisocial personality disorder with quetiapine.

There are few effective treatments of antisocial personality disorder (APD). Preliminary work suggests that the atypical antipsychotic quetiapine can decrease irritability, impulsivity, and aggressiveness. Data were collected from 4 patients with APD who were referred to a maximum-security inpatient psychiatric facility for pretrial evaluation and were treated with quetiapine. Quetiapine was effective in these patients as was indicated by a decrease in symptoms such as impulsivity, hostility, aggressiveness, irritability, and rage reactions. Typical dosage was 600 to 800 mg per day. Patients attributed their willingness to comply with quetiapine treatment to both the effectiveness of the drug and its favorable adverse-event profile. Quetiapine was successfully combined with mood stabilizers, particularly gabapentin, in patients with prominent affective instability. Quetiapine has demonstrated efficacy in aggression, impulsivity, and irritability and has proved to be an effective medication in these patients with APD. In addition, its favorable adverse-event profile makes patients willing to comply.

The role of gender in the clinical presentation of patients with borderline personality disorder.

This study examined gender differences in the pattern of comorbid disorders and degree of impairment among outpatients with borderline personality disorder (BPD). A total of 130 outpatients with BPD were assessed for various lifetime impulse-related disorders and post-traumatic stress disorder and for indices of impairment. Compared with women with BPD, men with BPD reported significantly more lifetime substance abuse disorders, antisocial personality and met criteria of intermittent explosive disorder that did not overlap with a diagnosis of BPD. Women with BPD reported significantly more lifetime eating disorders than men with BPD. No gender differences were found in degree of overall impairment. These results suggest that male and female patients with BPD, although equally distressed, present with different lifetime patterns of impulse-related disorders.

Study of impulse-control disorders among alcohol-dependent patients.

BACKGROUND: Impulse-control disorders (ICDs) include intermittent explosive disorder, kleptomania, trichotillomania, pyromania, and pathological gambling. Several studies have suggested that the incidence of pathological gambling is substantially higher in alcoholics than in the general population. The rate of co-occurrence of other ICDs and alcohol dependence has never been systematically investigated. In our study, we assessed the frequency of all ICDs in a population of alcohol-dependent patients. We also examined the possibility that the presence of an ICD can correspond to earlier onset and more severe forms of alcoholism, which have a greater association with antisocial personality. METHOD: All patients hospitalized at our psychiatric unit for detoxification between January and August 1997 met DSM-IV criteria for alcohol dependence and were included in this study. Diagnosis of alcohol dependence was confirmed with the Mini-International Neuropsychiatric Interview. ICDs were investigated using the Minnesota Impulsive Disorders Interview. All patients completed the Michigan Alcoholism Screening Test. RESULTS: Among the 79 patients included in the study, 30 (38.0%) met criteria for an ICD. Included in the study were 19 cases of intermittent explosive disorder, 7 cases of pathological gambling, 3 cases of kleptomania, and 1 case of trichotillomania. Patients with co-occurring ICDs were significantly younger than patients without an ICD (mean age = 40.7 vs. 44.5 years; p = .03). Patients with co-occurring pathological gambling were significantly younger at the onset of alcohol dependence than patients without ICDs (mean age = 19.5 vs. 25.9 years; p = .0008). Pathological gamblers had significantly longer duration of alcohol dependence compared with patients without ICDs (26.0 vs. 17.9 years; p = .02). Patients with co-occurring intermittent explosive disorder had the shortest duration of alcohol dependence of all patients (9.9 years). Prevalence of antisocial personality disorder was no different in patients with or without co-occurring ICDs. CONCLUSION: Thirty-eight percent of the alcohol-dependent patients studied presented with an ICD. Patients with ICDs were younger than those without an ICD. The presence of an ICD was not associated with a specific form of alcohol dependence or with antisocial personality. Co-occurrence of pathological gambling, however, was associated with lower age at onset of alcohol dependence, a higher number of detoxifications, and a longer duration of alcohol dependence than was absence of an ICD.

Self-injurious skin picking: clinical characteristics and comorbidity.

BACKGROUND: Repetitive skin picking, a self-injurious behavior that may cause severe tissue damage, has received scant empirical attention. The authors examined the demographics, phenomenology, and associated psychopathology in a series of 31 subjects with this problem. METHOD: Subjects were administered the Structured Clinical Interview for DSM-IV for Axis I and Axis II disorders. They also completed several mood questionnaires and a new self-report inventory designed to assess phenomenology, triggers, cognitions, emotions, and consequences associated with skin picking. RESULTS: The mean age at onset on self-injurious skin picking was 15 years, and the mean duration of illness was 21 years. All subjects picked at more than one body area, and the most frequent sites of skin picking were pimples and scabs (87%). The most common comorbid Axis I diagnoses were obsessive-compulsive disorder (OCD; 52%), alcohol abuse/dependence (39%), and body dysmorphic disorder (32%). Forty-eight percent (N = 15) of the subjects met criteria for at least one mood disorder, and 65% (N = 20) for at least one anxiety disorder. The most common Axis II disorders were obsessive-compulsive personality disorder (48%) and borderline personality disorder (26%). CONCLUSION: Self-injurious skin picking is a severe and chronic psychiatric and dermatologic problem associated with high rates of psychiatric comorbidity. It may be conceptualized as a variant of OCD or impulse-control disorder with self-injurious features and may, in some cases, represent an attempt to regulate intense emotions.

Gender differences in pathological gambling.

BACKGROUND: To determine the differences in clinical presentation, gambling behavior, and psychiatric comorbidity of male and female treatment-seeking pathological gamblers. METHOD: Sixty-nine consecutive individuals with DSM-IV pathological gambling (47 men and 22 women) applying to a specialized out-patient treatment program were evaluated with structured interviews, self-report questionnaires, and psychological scales. RESULTS: Sixty-seven percent of men (N = 26) versus 25% of women (N = 5) had been exposed to gambling in adolescence. Women had a later age at first bet and a faster evolution of the disorder. Female pathological gamblers were more likely to play bingo, whereas men tended to prefer slot machines. Male and female pathological gamblers had similar gambling severity and overall rates of psychiatric comorbidity. However, male pathological gamblers had higher rates of alcohol abuse/dependence and antisocial personality disorder, whereas women had higher rates of affective disorders and history of physical abuse. CONCLUSION: There are substantial gender differences in the clinical presentation and comorbidity of pathological gambling. These gender differences should be incorporated in the selection and planning of treatment for pathological gamblers.

Child firesetters: a clinical investigation.

The demographic, symptomatic, psychosocial and diagnostic profile of 104 child firesetters was investigated in a controlled case note and item sheet study of all children referred to an Inner London clinic between 1973 and 1981. Firesetters form a subgroup of severe conduct disorders, and are distinguished by a younger peak age of 8, higher boy/girl ratio and more marked psychosocial disturbance. The paper focuses on the relationships between background factors and firesetting, and also examines the relevance of enuresis and situational antecedents as specific determinants.
