The occurrence of inattention, hyperactivity, impulsivity and coexisting symptoms in a population study of 471 6-8-year old children based on the FTF (Five to Fifteen) questionnaire.

OBJECTIVE: To study the usefulness of a new parent questionnaire and to evaluate the prevalence of inattention, hyperactivity, impulsivity and co-existing problems in a group of 6-8-year-old children. METHOD: A questionnaire comprising 179 three-score-items including the DSM-IV diagnostic symptom criteria on AD/HD and questions on motor function, executive functions, perception, memory, language and speech, learning, social skills and psychiatric problems was used (5-15 questionnaire, FTF). The answers given by parents of 6-8-year-old children in a community in Finland are presented. RESULTS: The answers for 471 children, 230 boys and 241 girls, revealed a significantly higher rate of problems for boys than for girls in all developmental domains. The number of children with scores exceeding the mean +2 SD for inattention and/or hyperactivity-impulsivity subdomains were 42. About an half of these children had many coexisting problems, when the 90(th) percentile score for each domain was used as a measurement. Of the 42 children 11 fulfilled the DSM-IV symptom list criteria (6/9 for inattention and/or hyperactivity-impulsivity) for AD/HD and 9 children for subthreshold (5/9) AD/HD. CONCLUSION: A community-based study revealed that 2.3% of 6-8-year-old children had the full symptom list criteria (6/9) of AD/HD according to DSM-IV, and another 1.9 % fulfilled the symptom criteria (5/9) for subthreshold AD/HD. Coexisting problems were common. The severity of symptoms of inattentiveness and hyperactivity-impulsivity correlated significantly with the severity of coexisting problems.

Remission from pathological gambling among Hispanics and Native Americans.

This community survey studied remission from pathological gambling (PG) among American Indian (AI) and Hispanic American (HA) veterans. Remission was defined as having a lifetime diagnosis of PG, but no gambling symptoms in the last year. Sample consisted of 1624 AI and Hispanic veterans. Instruments included demographic data, the computer-based algorithmic Quick Diagnostic Interview Schedule Symptom, and three symptom checklists, one each for substance related problems (MAST/AD), anxiety and depressive symptoms (BSI-57), and combat-related post-trauma symptoms (PCL/M). Remission was associated with absence of a current Axis 1 diagnosis, especially absence of a current post-traumatic stress disorder.

Gambling screens: does shortening the time frame affect their psychometric properties?

Gambling screening tools such as the South Oaks Gambling Screen (SOGS) and a DSM-IV Screen for Gambling Problems (NODS) developed by the National Opinion Research Council have psychometrically validated lifetime and past-year versions. As research questions often dictate shorter time intervals, researchers have adapted the time frames of these instruments to their specific purposes without examining whether changing the time frame affects the psychometric properties. In this study, 3-month versions of SOGS and NODS were administered to a sample of 80 pathological gamblers (59 men, 21 women, mean age 44) seeking treatment at a state-funded facility. The 3-months versions had good internal consistency, good convergent validity with each other, with gambling behaviors assessed via the timeline followback method, and with measures of impulsivity. The 3-month versions also showed good discriminant validity with demographic variables and a measure of verbal IQ. Together the data indicate that shortening the time frame to 3 months does not seem to have adverse effects on the psychometric properties of SOGS and NODS. Thus these adapted versions could profitably be used for shorter time intervals, including as pre/post-treatment and follow-up measures in treatment outcome studies.

A psychometric evaluation of the DSM-IV pathological gambling diagnostic criteria.

Specific diagnostic criteria for pathological gambling (PG) have been available for 25 years, since the publication of DSM-III. Little research has examined the psychometric performance of the diagnostic criteria. The goal of the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project was to examine the sensitivity, specificity and predictive values of the DSM-IV PG criteria for psychiatric outpatients who screened positive for a gambling problem. A total of 1709 psychiatric outpatients were evaluated with a semistructured diagnostic interview for PG. Of all patients 88 screened positive for PG, 40 of whom met DSM-IV diagnostic criteria for a lifetime history of PG. All ten DSM-IV criteria were significantly more frequent in the PG group. The sensitivity of the criteria ranged from 25.0% to 90.0% (mean = 67.8%), whereas specificity ranged from 62.5% to 100% (mean = 81.9%). Positive predictive values ranged from 64.1% to 100% (mean = 78.9%), and negative predictive values ranged from 61.5% to 90.7% (mean = 77.1%). Guidelines are recommended for determining whether a diagnostic criterion should be retained as part of the set of diagnostic criteria, and our results suggested that two of the DSM-IV PG criteria are candidates for elimination (criterion 8--commitment of illegal acts; criterion 10--reliance on others for financial assistance to relieve a desperate financial problem).

Phenomenologic relationship of eating disorders to major affective disorder.

We administered the National Institute of Mental Health Diagnostic Interview Schedule to 41 patients with a lifetime history of anorexia nervosa (25 with and 16 without bulimia) and to 49 patients with bulimia alone. Results showed that 77% of the patients with eating disorders had a lifetime diagnosis of DSM-III major affective disorder, a rate significantly higher than that found in comparison groups composed of the first-degree relatives of probands with schizophrenia and bipolar disorder. High lifetime rates of anxiety disorders, substance use disorders, and kleptomania were also observed. By contrast, few cases of personality disorders and no cases of schizophrenia were found. These findings combine with the results of studies of family history, long-term outcome, response to biological tests, and treatment response to suggest that anorexia nervosa and bulimia may be closely related to major affective disorder.

Disinhibition and negative affectivity in substance abusers with and without a gambling problem.

A cohort of 2,171 substance abusers were assessed for their gambling behavior, and divided into three groups: those with no significant gambling problem (87%); those with a probable problem (7.2%); and those with a severe problem (5.8%). Substance abusers with a gambling problem scored significantly higher on measures of: impulsivity; disinhibition of aggressive/hostile responses; and negative affectivity. They also abused more substances than the nongamblers. The results underscore the importance of assessing a wide range of impulsive behaviors in substance abusers and the potential for subtyping substance abusers based on psychological traits.

Using the NORC DSM Screen for Gambling Problems as an outcome measure for pathological gambling: psychometric evaluation.

The National Opinion Research Center DSM Screen for Gambling Problems (NODS), a population-based telephone-screening tool to identify gambling problems according to DSM-IV criteria, was examined as a potential outcome measure for gambling treatment studies. The NODS was administered to problem gamblers as part of a 1-year follow-up after a brief treatment. Internal reliability was fair to good and the factor structure and item-total correlations supported the existence of a single construct with three subfactors, measuring negative behavioral consequences, preoccupation and impaired control over gambling and tolerance, and withdrawal and relief gambling. The NODS total score correlated moderately with gambling behavior and outcome as predicted. The total score also correlated highly with the total score of the South Oaks Gambling Screen (SOGS) although the NODS and SOGS categorization of nonproblem, problem, and pathological gamblers showed poor agreement. The NODS, as designed, provided a more strict definition of disordered gambling than the SOGS. In summary, the NODS shows promise as an outcome measure of gambling problems.

Adolescent lottery and scratchcard players: do their attitudes influence their gambling behaviour?

This paper examines the link between attitudes and behaviour in relation to adolescent participation on the National Lottery and scratchcards by applying the theory of planned behaviour. A questionnaire constructed by the authors was administered to a sample of 1195 adolescents between the ages of 11 and 15 years (550 male, 641 female, 4 unspecified). In this paper, all data relating to factors associated with adolescent attitudes toward the National Lottery and scratchcards, and the links with any subsequent gambling behaviour, were analysed. Results revealed that young people's attitudes are an accurate predictor of their gambling behaviour on these activities, and that social cognitive theory provides an explanation of how these attitudes may develop. In light of these findings, a number of suggestions are given on how to discourage young people from gambling.

Retrospective review of treatment retention in pathological gambling.

Although research on pathological gambling is increasing, there are few studies examining correlates of treatment retention. In the current study, 50 outpatients with a primary DSM-IV diagnosis of pathological gambling treated in a clinical practice were assessed by chart review. Standard scales were used to rate subjects at baseline and at 2-month intervals. Subjects who dropped out of treatment were contacted by telephone to determine reasons for discontinuation of treatment. The mean duration of follow-up was 360.4 +/- 352.2 days. Twenty-four (48%) of the subjects discontinued treatment, including 14 (36.8%) of those subjects who were responders (defined as Clinical Global Impression [CGI] scale of "very much" or "much" improved) during at least one assessment point. Of those who discontinued treatment, 41.7% reported missing the thrill of gambling and 20.8% reported feeling certain that they could win and relieve financial burdens. Predictors of treatment continuation were responding to treatment within 8 weeks (odds ratio [OR], 6.00; 95% confidence interval [CI], 1.13 to 32.00; P =.04) and having a supportive environment (OR, 22.99; 95% CI, 5.04 to 104.76; P <.001). We conclude that a large percentage of patients with pathological gambling discontinue treatment. Predictors of treatment continuation may have clinical importance. Prospective longitudinal studies are needed to further elucidate the course of pathological gambling.

Impulsive disorders in Japanese adult patients with obsessive-compulsive disorder.

In this study, we sought to characterize obsessive-compulsive disorder (OCD) patients with impulsive features, and to determine whether they constitute a distinct subtype of OCD. Therefore we systematically assessed impulse control disorders and other impulsive conditions categorized as obsessive-compulsive spectrum disorders (OCSDs) in 153 Japanese adult patients with OCD. Forty-five subjects (29%) had concurrent impulsive disorders, and they were differentiated from other OCD patients on a range of demographic features (e.g., younger age at onset), and clinical features (e.g., pervasive and severe psychopathology, and poor treatment outcome). However, on logistic regression, none of these variables predicted comorbid impulsivity. The findings appear to support the argument that OCD patients with impulsive features constitute a subtype of OCD. However, further research is necessary to determine whether impulsivity should be conceptualized as lying on a spectrum with compulsivity or as a dimension that is orthogonal to compulsivity.

Dissociation and fantasy proneness in psychiatric patients: a preliminary study.

Nonclinical studies found that dissociative experiences are intimately linked to a trait known as fantasy proneness. We examined the links among dissociative symptoms, fantasy proneness, and impulsivity in psychiatric outpatients. Our sample consisted of 22 patients with schizophrenia, 20 patients with a diagnosis of borderline personality disorder, and 19 patients with a major depressive disorder. For the whole sample, levels of dissociation were found to be related to fantasy proneness and impulsivity. There were group differences in dissociative symptoms, with patients with borderline personality disorder reporting more such symptoms than patients with either schizophrenia or major depressive disorder. The overlap between dissociation and fantasy proneness may have important ramifications for studies addressing comorbid phenomena of dissociative symptoms.

Randomized, placebo-controlled trial of sertraline and contingency management for the treatment of methamphetamine dependence.

BACKGROUND: Methamphetamine dependence and associated medical and psychiatric concerns are significant public health issues. This project evaluated the efficacy of sertraline (50mg bid) and contingency management (CM) for the treatment of methamphetamine dependence. METHOD: In this randomized, placebo-controlled, double-blind trial, participants completed a 2-week non-medication baseline and were randomized to one of four conditions for 12 weeks: sertraline plus CM (n=61), sertraline-only (n=59), matching placebo plus CM (n=54), or matching placebo-only (n=55). All participants attended clinic thrice-weekly for data collection, medication dispensing, and relapse prevention groups. Outcomes included methamphetamine use (urine drug screening and self-reported days of use), retention (length of stay), drug craving (visual analogue scale), and mood symptoms (Beck Depression Inventory). RESULTS: No statistically significant main or interaction effects for sertraline or CM in reducing methamphetamine use were observed using a generalized estimating equation (GEE), although post hoc analyses showed the sertraline-only condition had significantly poorer retention than other conditions (chi(2) (3)=8.40, p<0.05). Sertraline conditions produced significantly more adverse events than placebo conditions. A significantly higher proportion of participants in CM conditions achieved three consecutive weeks of methamphetamine abstinence than those in non-CM conditions. CONCLUSIONS: These data do not demonstrate improved outcomes for sertraline versus placebo for treatment of methamphetamine dependence; indeed, they suggest sertraline is contraindicated for methamphetamine dependence. Findings provide support for the use of contingency management for treatment of methamphetamine dependence.

Performance monitoring and stop signal inhibition in abstinent patients with cocaine dependence.

Impulsivity has been associated with drug abuse and relapse. As a measure of impulsivity, response inhibition in a stop signal task is impaired in substance abusers compared to healthy control subjects. However, cognitive processes besides response inhibition can affect performance in the stop signal task. Greater response readiness to the go signal increases stop signal reaction time (SSRT) and greater performance monitoring elicited by the stop signal decreases SSRT. Prolonged SSRT, therefore, may reflect differences in these other task-related cognitive processes rather than impaired response inhibition. Using a tracking stop-signal task, we compared 18 abstinent cocaine dependent patients with 41 age- and education-matched healthy controls. We computed SSRT for each individual subject on the basis of the horse race model. We also computed the fore-period (FP) effect to measure response readiness to the go signal and the post-signal slowing (PSS) effect to measure performance monitoring to the stop signal. Cocaine subjects showed increased SSRT and decreased PSS effect, compared to healthy controls. Covariance adjustment for the PSS effect eliminated the SSRT difference from healthy controls. These results suggest that diminished performance monitoring can be a critical cognitive mechanism underlying impaired response inhibition in cocaine dependent patients.

Incidence and patterns of polydrug use and craving for ecstasy in regular ecstasy users: an ecological momentary assessment study.

BACKGROUND: Previous studies employing retrospective assessments methods found that regular ecstasy users frequently use alcohol, marihuana and other drugs in combination with ecstasy. METHODS: Twenty-two participants (13 males, 9 females) wore a wrist actigraph/data recorder to record real-time drug use and ecstasy craving for 6 weeks. Rates of alcohol and drug use on ecstasy use versus non-use nights, and before, during, and after ecstasy use were analyzed with generalized estimation equations (GEE). Craving was modeled with GEE and linear mixed models. RESULTS: Approximately 70% of ecstasy uses occurred on Friday or Saturday nights. No drug was significantly more likely to be used on ecstasy use nights than comparison Friday and Saturday nights. On nights ecstasy was used, in general across all drugs assessed, use was more likely before and during than after ecstasy intoxication, while alcohol use was also more likely before than during ecstasy intoxication. Though low overall, craving for ecstasy increased over 24 h before use and was higher on Friday nights of weeks ecstasy was used on weekends than weeks it was not used. CONCLUSIONS: Use of ecstasy on a particular night may not be associated with any greater likelihood of using any other intoxicating drug, and use of other drugs on nights involving ecstasy use may simply reflect a "natural history" of drug-use nights that begins with alcohol, progresses to more intoxicating drugs, and ends with little drug use. Confirmation of these findings awaits further advances in the application of ecological momentary assessment methodologies.

Comorbid psychiatric diagnoses in kleptomania and pathological gambling: a preliminary comparison study.

Kleptomania and pathological gambling (PG) are currently classified in the DSM IV as impulse control disorders. Impulse control disorders are characterized by an overwhelming temptation to perform an act that is harmful to the person or others. The patient usually feels a sense of tension before committing the act and then experiences pleasure or relief while in the process of performing the act. Kleptomania and PG are often associated with other comorbid psychiatric diagnoses. Forty-four pathological gamblers and 19 kleptomanics were included in this study. All enrolled patients underwent a complete diagnostic psychiatric evaluation and were examined for symptoms of depression and anxiety using the Hamilton depression rating scale and the Hamilton anxiety rating scale, respectively. In addition, the patients completed self-report questionnaires about their demographic status and addictive behavior. The comorbid lifetime diagnoses found at a high prevalence among our kleptomanic patients included 47% with affective disorders (9/19) and 37% with anxiety disorders (7/19). The comorbid lifetime diagnoses found at a high prevalence in our sample of pathological gamblers included 27% with affective disorders (12/44), 21% with alcohol abuse (9/44), and 7% with a history of substance abuse (3/44). A larger study is needed to confirm these preliminary results.

Questionnaire ratings of attention-deficit/hyperactivity disorder (ADHD) in adults are associated with spatial working memory.

OBJECTIVE: Data related to brain function may have the potential to improve the reliability and validity of assessments for the aetiologically and clinically heterogeneous syndrome of attention-deficit/hyperactivity disorder (ADHD). This study investigated associations between questionnaire assessments of behavioural features of adults with ADHD and an aspect of neurocognitive performance which has been reported to be impaired in adults with ADHD. METHODS: Fifty-nine adult patients with a DSM-IV diagnosis of ADHD, and their informants, completed questionnaires related to aspects of severity of ADHD. Associations were examined between questionnaire ratings and performance on a computer-administered task of spatial working memory (SWM). RESULTS: Correlations between ratings of ADHD and SWM indicated moderate but significant correlations for patients' ratings, but not for informants' ratings. Also, patients who reported a past history of 'self-harm' (N=33) had a significantly worse mean performance on both measures of SWM (p=0.004, 0.003). CONCLUSIONS: The results indicate that aspects of impulsivity, i.e. self-ratings of 'emotive' behaviour (involving rapid response to stimuli and marked reactivity of mood) and of past 'self-harm', show relatively strong associations with SWM performance in adults selected on the basis of an ADHD diagnosis. A profile of neurocognitive performances may have a role in the assessment of ADHD.
