Assessment and management of pathological and problem gambling among older adults.

The incidence of gambling among older adults has risen significantly over the last decade. Pathological and problem gambling disorders among older adults have devastating consequences including stress, alcohol abuse, loss of income and assets, treatment nonadherence, malnutrition, safety risks related to associated alcohol usage and financial losses, and increased psychiatric problems such as depression. This article reviews the theoretical frameworks and literature concerning gambling incidence, prevalence, behavior, diagnostic tools and interventional strategies for older adults, as well as nursing assessment, care planning, and management of gambling disorders.

Internet addiction in Korean adolescents and its relation to depression and suicidal ideation: a questionnaire survey.

This study examined the relationship of Internet addiction to depression and suicidal ideation in Korean adolescents. The participants were 1573 high-school students living in a city who completed the self-reported measures of the Internet Addiction Scale, the Korean version of the Diagnostic Interview Schedule for Children-Major Depression Disorder-Simple Questionnaire, and the Suicidal Ideation Questionnaire-Junior. A correlational survey design was employed. Among the samples, 1.6% was diagnosed as Internet addicts, while 38.0% was classified as possible Internet addicts. The prevalence of Internet addiction did not vary with gender. The levels of depression and suicide ideation were highest in the Internet-addicts group. Future studies should investigate the direct relationship between psychological health problems and Internet dependency.

Pathological gambling and mood disorders: clinical associations and treatment implications.

BACKGROUND: The rapidly expanding gambling business has resulted in an increasing number of gamblers, and the problem is likely to get worse in the future. Traditionally, mood and gambling symptoms have been known to overlap. In the present review we attempt to examine the diagnostic associations and implications for treatment. METHOD: Selected published papers on the frequencies of mood disorders among patients who have gambling disorder or gambling disorder among patients who have mood disorder have been reviewed. Recently emerging new treatment methods for gambling disorder have been reviewed and a brief summary has been added. RESULTS: SCID based study results show a close link between gambling and mood disorders. The prevalence of manic disorder reaches to approximately one fourth of the pathological gambling disorder population. The prevalence of depression is much higher, reaching to over half of the population in some studies. LIMITATIONS: The studies included in the present paper involve inpatients, outpatients, subjects recruited through advertisements and prison populations. Thus the data need to be interpreted as such. Standardized assessment instruments are not used in all studies. Methodological issues such as primary or secondary nature of depression have not been addressed adequately in these studies. The findings, however, offer new insights for the assessment and treatment of complicated gambling disorder cases. CONCLUSIONS: A high prevalence rate of manic and depressive disorders has been recorded among pathological gambling disorder patients. A rational treatment approach to each defined subset of complicated gambling disorder is discussed.

Toward an integrative model of the spectrum of mood, behavioral and personality disorders based on fear and anger traits: I. Clinical implications.

Current formal psychiatric approaches to nosology are plagued by an unwieldy degree of heterogeneity with insufficient appreciation of the commonalities of emotional, personality, behavioral, and addictive disorders. We address this challenge by building a spectrum model that integrates the advantages of Cloninger's and Akiskalian approaches to personality and temperament while avoiding some of their limitations. We specifically propose that "fear" and "anger" traits--used in a broader connotation than in the conventional literature--provide an optimum basis for understanding how the spectra of anxiety, depressive, bipolar, ADHD, alcohol, substance use and other impulse-control, as well as cluster B and C personality disorders arise and relate to one another. By erecting a bidimensional approach, we attempt to resolve the paradox that apparently polar conditions (e.g. depression and mania, compulsivity and impulsivity, internalizing and externalizing disorders) can coexist without cancelling one another. The combination of excessive or deficient fear and anger traits produces 4 main quadrants corresponding to the main temperament types of hyperthymic, depressive, cyclothymic and labile individuals, which roughly correspond to bipolar I, unipolar depression, bipolar II and ADHD, respectively. Other affective temperaments resulting from excess or deficiency of only fear or anger include irritable, anxious, apathetic and hyperactive. Our model does not consider schizophrenia. We propose that "healthy" or euthymic individuals would have average or moderate fear and anger traits. We further propose that family history, course and comorbidity patterns can also be understood based on fear and anger traits. We finally discuss the implications of the new derived model for clinical diagnosis of the common psychiatric disorders, and for subtyping depression and anxiety as well as cognitive and behavioral styles. We submit this proposed schema represented herein as a heuristic attempt to build bridges between basic and clinical science.

Trait impulsivity in patients with mood disorders.

BACKGROUND: Impulsivity is a key component of the manic behavior of bipolar disorder and is reported to occur in bipolar patients as a stable characteristic, i.e. a trait. Nevertheless, impulsivity has not been widely studied in depressed bipolar patients. We assessed impulsivity in depressed and euthymic bipolar and unipolar patients and healthy controls. We hypothesized that bipolar subjects would have higher levels of trait impulsivity than the comparison groups. METHODS: Twenty-four depressed bipolar, 24 depressed unipolar, 12 euthymic bipolar, and 10 euthymic unipolar patients, as well as 51 healthy subjects were evaluated with the Barratt Impulsiveness Scale (BIS). Analysis of covariance with age and sex as covariates was used to compare mean group differences. RESULTS: Depressed bipolar, euthymic bipolar, and depressed unipolar patients did not differ, and showed greater impulsivity than healthy controls on all of the BIS scales. Euthymic unipolar patients scored higher than healthy controls only on motor impulsivity. LIMITATIONS: Higher number of past substance abusers in the bipolar groups, and no control for anxiety and personality disorders, as well as small sample sizes, limit the reach of this study. CONCLUSIONS: This study replicates prior findings of stable trait impulsivity in bipolar disorder patients, and extends them, confirming that this trait can be demonstrated in depressed patients, as well as manic and euthymic ones. Trait impulsivity may be the result of repeated mood episodes or be present prior to their onset, either way it would influence the clinical presentation of bipolar disorder.

Impulse control disorders in adults with obsessive compulsive disorder.

Little is known about impulse control disorders (ICDs) in individuals with obsessive compulsive disorder (OCD). Although studies have examined ICD comorbidity in OCD, no previous studies have examined clinical correlates of ICD comorbidity in a large sample of individuals with a primary diagnosis of OCD. We examined rates and clinical correlates of comorbid ICDs in 293 consecutive subjects with lifetime DSM-IV OCD (56.8% females; mean age=40.6+/-12.9 years). Comorbidity data were obtained with the Structured Clinical Interview for DSM-IV. ICDs were diagnosed with structured clinical interviews using DSM-IV criteria. OCD severity was assessed with the Yale-Brown Obsessive-Compulsive Scale. Quality of life and social/occupational functioning were examined using the Quality of Life Enjoyment and Satisfaction Questionnaire and the Social and Occupational Functioning Assessment Scale. All variables were compared in OCD subjects with and without lifetime and current ICDs. Forty-eight (16.4%) OCD subjects had a lifetime ICD, and 34 (11.6%) had a current ICD. Skin picking was the most common lifetime (10.4%) and current (7.8%) ICD, followed by nail biting with lifetime and current rates of 4.8% and 2.4%, respectively. OCD subjects with current ICDs had significantly worse OCD symptoms and poorer functioning and quality of life. These preliminary results suggest that there is a low prevalence of ICDs among individuals with OCD, although certain ICDs (skin picking) appear to be more common.

Does work on obsessive-compulsive spectrum disorders contribute to understanding the heterogeneity of obsessive-compulsive disorder?

BACKGROUND: There is a growing literature on the concept of an obsessive-compulsive spectrum of disorders. Here, we consider the different dimensions on which obsessive-compulsive spectrum (OCSDs) lie, and focus on how the concepts from this literature may help understand the heterogeneity of obsessive-compulsive disorder (OCD). METHODS: A computerized literature search (MEDLINE: 1964-2005) was used to collect studies addressing different dimensions on which the OCSDs lie. Against this backdrop, we report on a cluster analysis of OCSDs within OCD. RESULTS: OCSDs may lie on several different dimensions. Our cluster analysis found that in OCD there were 3 clusters of OCD spectrum symptoms: (1) "Reward deficiency" (including trichotillomania, pathological gambling, hypersexual disorder and Tourette's disorder), (2) "Impulsivity" (including compulsive shopping, kleptomania, eating disorders, self-injury and intermittent explosive disorder), and (3) "Somatic" (including body dysmorphic disorder and hypochondriasis). CONCLUSIONS: It is unlikely that OC symptoms and disorders fall on any single phenomenological dimension; instead, multiple different constructs may be required to map this nosological space. Although there is evidence for the validity of some of the relevant dimensions, additional work is required to delineate more fully the endophenotypes that underlie OC symptoms and disorders.

Predicting borderline and antisocial personality disorder features in nonclinical subjects using measures of impulsivity and aggressiveness.

This study examines impulsivity and aggressiveness dimensions as predictors of borderline (BPD) and antisocial (ASPD) personality disorder symptoms in nonclinical subjects. A total of 747 undergraduate university students were administered the Personality Diagnostic Questionnaire-4+, the Barratt Impulsiveness Scale-11, and the Buss-Durkee Hostility Inventory. Hierarchical regression analysis showed that motor impulsiveness, irritability, resentment, and guilt predicted BPD symptoms among university students after controlling for the effect of ASPD and depressive symptoms. ASPD symptoms were predicted by motor impulsiveness, physical aggression, indirect aggression, and negativism. These results indicate that in nonclinical subjects BPD and ASPD symptoms share a common impulsivity dimension but are linked to different aggressiveness facets.

Alpha 2A adrenergic receptor gene and suicide.

Suicide is a complex trait resulting from the interaction of several predisposing factors, among which genes seem to play an important role. Alterations in the noradrenergic system have been observed in postmortem brain studies of suicide victims when compared to controls. The purpose of this study was to test the hypothesis that genetic variants of the alpha(2A) adrenergic receptor gene are implicated in suicide and/or have a modulatory effect on personality traits that are believed to mediate suicidal behavior. We studied a sample of suicides (N=110) and control subjects (N=130) for genetic variation at four loci, including three in the promoter region (g-1800t, c-1291 g and the g-261a) of the alpha(2A) adrenergic receptor gene, and a potentially functional locus, N251K, which leads to an amino acid change (asparagine to lysine). No significant differences were observed at the promoter loci in terms of allelic or genotypic distribution between suicides and controls. However, analysis of the functional polymorphism N251K revealed that the 251 K allele was only present among suicides, though only three suicide cases had this allele, two of which were homozygous. These results are preliminary. If confirmed, they suggest that variation at the alpha(2A) adrenergic receptor gene may play a role in a small proportion of suicide cases.

High sensitivity to punishment and low impulsivity in obsessive-compulsive patients with hoarding symptoms.

Recent factor-analytic studies involving over 2000 patients have reduced the symptoms of obsessive-compulsive disorder (OCD) into a few dimensions or potentially overlapping syndromes. Hoarding consistently emerged as a separate factor in all these studies. This study investigated the relationship between OCD symptom dimensions and normal personality traits in a sample of 56 OCD patients. They were administered the Sensitivity to Punishment and Sensitivity to Reward Questionnaire and the Eysenck Personality Questionnaire, derived from Gray's and Eysenck's personality models, respectively. The personality scores were correlated with previously identified symptom dimensions from the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (Y-BOCS-SC), controlling for overall illness severity. High scores on the hoarding dimension of the Y-BOCS-SC were positively correlated with scores on the Sensitivity to Punishment scale and negatively with Eysenck's Psychoticism scale. While high sensitivity to punishment is a personality feature common to many OCD patients, it is more strongly pronounced in patients with hoarding symptoms. These patients also appear to be less impulsive or novelty seeking as reflected by low scores on Eysenck's Psychoticism scale. High sensitivity to punishment and low novelty seeking in OCD hoarders might explain their poor compliance and response to conventional treatments, but this question needs to be explored further in a prospective treatment study.

Preliminary validity and reliability testing of a structured clinical interview for pathological gambling.

The psychometric properties of a clinician-administered, DSM-IV-based, structured clinical interview for pathological gambling (SCI-PG) were examined. Seventy-two consecutive subjects requesting treatment for gambling problems were administered the SCI-PG. Reliability and validity were determined. Classification accuracy was examined using longitudinal course of illness. The SCI-PG demonstrated excellent inter-rater and test-retest reliability. Concurrent validity was observed with the South Oaks Gambling Screen (SOGS). Discriminant validity was observed with measures of anxiety and depression. The SCI-PG demonstrated both high sensitivity and specificity based on longitudinal assessment. The SCI-PG demonstrated excellent reliability and validity in diagnosing PG in subjects presenting with gambling problems. These findings require replication in other groups to examine their generalizability.

Cholesterol-lowering therapy evokes time-limited changes in serotonergic transmission.

A number of studies have reported an increased risk for violent deaths and depression in subjects with reduced serum cholesterol concentrations. Links with hypothesized impairment of serotonin neurotransmission have not been satisfactorily tested. In this investigation, the serum and membrane cholesterol, microviscosity of erythrocyte membranes, platelet serotonin uptake, and clinical parameters were determined during pharmacotherapy of 17 hypercholesterolemic patients. A significant decrease in serum cholesterol and a nonsignificant decrease in membrane cholesterol concentration were found after 2 months of simvastatin therapy. Serotonin transporter (SERT) activity was significantly increased following 1 month of simvastatin; the tendency to decrease the initial increase in SERT activity was evident following 2 months of therapy. Both membrane cholesterol and SERT activity returned to pre-treatment levels after more than 1 year of therapy. Microviscosity of plasma membranes, impulsivity, empathy, adventure, sensation seeking, and depressed mood were not markedly changed. These data indicate that long-term therapy has different effects on serotonin transmission from short-term (1- to 2-month) therapy. A significant increase in SERT activity was detected only during the first month of simvastatin therapy. This finding suggests that within this period some patients could be vulnerable to depression, violence, or suicide.

Impulsivity in depressed children and adolescents: a comparison between behavioral and neuropsychological data.

Impulsivity at the neuropsychological and behavioral levels was investigated in a sample of drug-naive depressed children and adolescents. The performance of 21 patients with a current diagnosis of mood disorder was compared with that of 21 normal controls on tests of executive functions related to impulsivity (Matching Familiar Figures Test, Continuous Performance Test, Verbal Fluency, Stroop Test, and Walk-Don't Walk) and on impulsive/restless behavior on the Conners' Parent Rating Scale. Depressed children and adolescents showed a pattern of conservative response style, with slow reaction times and attentional problems, similar to that observed in adults, and a general delay/difficulty in response initiation on the Fluency Test. Depressed participants were rated by their parents as being significantly more impulsive/restless than controls. However, there was no evidence of an impulsive cognitive response style in more impulsive/restless patients. Symptom severity (Hamilton Rating Scale for Depression) and subjective mood state (Children's Depression Inventory) were also taken into account.

A dimensional approach to personality in atypical depression.

The current study addresses the relationship of personality and atypical depression using the Five-Factor Model (FFM), a dimensional approach to personality. The aim of the study was to help clarify which personality traits are more characteristic of atypical depression than of other depressive subtypes. Outpatients (n=160) with non-psychotic major depression were characterized as having atypical (n=26), or non-atypical depression (n=134) based on DSM-IV criteria. To limit the effect of state depression, personality was assessed after subjects received a minimum of 14 weeks of antidepressant treatment. The Revised NEO Personality Inventory, which generates data based on the FFM, was the primary assessment measure. Post-treatment, relative to the non-atypical comparison group, the atypical group had significantly higher scores on the dimension of Neuroticism, the facets of Impulsivity and Anger-Hostility, and a significantly lower score on the facet of Deliberation. In sum, the FFM provides a new understanding of which unique personality characteristics may be associated with atypical depression.

Impulsivity, aggressiveness, and DSM-IV personality disorders.

The aim of this study is to assess whether impulsive and aggressive traits can be placed on a continuum with DSM-IV Cluster B Personality Disorders (PDs) and to determine if different aspects of these personality traits are specifically associated with individual Cluster B PDs. The study group comprised 461 outpatients admitted consecutively to a clinic that specializes in the diagnosis and treatment of PDs. Principal component analyses clearly suggested a five-factor structure of both normal and psychopathological personality traits. Importantly, measures of impulsivity, aggressiveness and novelty seeking formed a part of the principal component that clustered all Cluster B PDs. Regression analyses indicated that impulsive traits were selectively associated with Borderline PD whereas different aspects of aggressiveness were useful in discriminating Narcissistic PD from Antisocial PD. Sensation seeking traits formed a part of Histrionic PD. These results indicate that impulsive/aggressive traits may be useful in explaining both why Cluster B PDs tend to covary, and why they frequently differ in clinical pictures and courses.

Early visual information processing deficit in depression with and without Borderline Personality Disorder.

Backward masking is a measure of early visual information processing usually abnormal in psychotic disorders. Previous studies of subjects with Borderline Personality Disorder have been inconsistent regarding their impairment or lack of impairment on backward masking. We examined visual backward masking performance in samples of unmedicated depressed patients with (n=12) and without (n=16) Borderline Personality Disorder, and healthy volunteers (n=18). Accuracy was poorer in depressed BPD patients, relative to both non-BPD depressed and healthy comparison subjects. As in previous studies, no differences in accuracy were found between non-BPD depressed patients and healthy comparison subjects. Differences in BPD subjects' accuracy were most evident at the fastest ISI and were not attributable to intercurrent psychotic symptoms. Beyond these group differences, accuracy at faster ISI's correlated with self-ratings of impulsiveness in all patients, and may be a general correlate of this trait. Poor early information processing appears to be a feature of Borderline Personality Disorder, and may play a role in the impulsive behavior that is characteristic of the disorder.

Short scales for measuring schizotypy.

BACKGROUND: This study reports short scales for measuring several dimensions of schizotypy in the normal population based on a large twin sample. METHODS: The four short scales use items drawn from a longer instrument, the Oxford-Liverpool Inventory of Feelings and Experiences. Using concordance estimates from MZ and DZ pairs, the items were selected both to have a high heritability and to offer broad coverage of each trait domain. RESULTS: Preliminary descriptive statistics are reported for the short scales and suggest adequate reliability. CONCLUSIONS: New scales offer a time efficient and reliable method of studying proneness to psychosis in large N designs.
