Compulsive shopping: A review and update.

The author comprehensively reviews compulsive shopping (CS), a disorder characterized by excessive shopping and/or spending that leads to subjective distress and impaired functioning. CS has been linked to substance use disorders, mood, and anxiety disorders, and to the obsessive-compulsive spectrum. More recently, CS has been considered a behavioral addiction. Most CS experts consider CS an independent disorder. CS has an estimated prevalence of 5% in the United States general population with an onset in the late teens/early 20s. Psychiatric comorbidity is common, including mood, anxiety, substance use, and personality disorders. Little is known about its neurobiology and genetics. There are no standard treatments, but cognitive-behavioral group therapy appears promising. Future research should focus on validating the disorder and developing effective treatments.

Factor structure of borderline personality disorder and response to Systems Training for Emotional Predictability and Problem Solving.

Differential response to the Systems Training for Emotional Predictability and Problem Solving (STEPPS) program was compared in subgroups identified through latent class analysis (LCA). STEPPS is an evidence-based group treatment program for patients with borderline personality disorder (BPD). A reanalysis of data was conducted using data from a 20-week randomized controlled trial and 1-year follow-up. Subjects (n = 164) with DSM-IV BPD were assessed for comorbid Axis I and II disorders and selected clinical variables. Severity was assessed using the Zanarini Rating Scale for BPD (ZAN-BPD) and the Borderline Evaluation of Severity Over Time (BEST). Three- and four-class models were identified with the four-class model having the better fit. The latter included a high severity (HS) class (26%), an affective instability/substance abuse (AISA) class (16%), an empty/dissociation/identity disturbance (EDID) class (27%), and a low severity (LS) class (30%). High impulsiveness predicted membership in the HS class. Improvement was determined using a linear mixed-effects model. Those most likely to benefit were those in the HS group characterized by high symptom severity, Axis I and II comorbidity, problem relationships, abandonment fears, and intense anger. This work should help further efforts to match patients with treatments based on sociodemographic, diagnostic, and other illness characteristics.

Testing the Validity of the Pathways Model: A Latent Class Analysis of Potential Pathological Gambling Subtypes in a Non-Treatment Sample.

Latent class analysis (LCA) was used to test the validity of the Pathways Model in 285 subjects with DSM-IV pathological gambling (PG). In addition to identifying three subtypes that roughly correspond with those described in the model (Behaviorally Conditioned, or BC, Emotionally Vulnerable, or EV, Antisocial-Impulsivist, or AI), LCA identified a fourth class, termed the Antisocial Drinker, or AD, characterized by high rates of antisociality, conduct disorder, and alcohol use disorder. BC gamblers comprised 45% of the sample, followed by EV (24%), AD (22%), and AI (9%) gamblers. Women were more likely to be EV gamblers (OR = 1.89) and less likely to be AD gamblers (OR = 0.46). Those who had attempted suicide were more likely to be EV (OR = 3.06) or AI (OR = 3.05) gamblers and less likely to be BC (OR = 0.37) or AD gamblers (OR = 0.50). Greater childhood maltreatment was associated with AD (standardized OR = 1.81) and AI (standardized OR = 1.43) gamblers. Individuals with later PG onset were less likely to be AI gamblers (standardized OR = 0.48). Individuals who preferred slots were more likely to be EV gamblers (OR = 1.83) and less likely to be AD gamblers (OR = 0.33). The BC subtype was associated with better health outcomes, better social functioning, less childhood maltreatment, and less severe PG. The AI subtype was associated with worse health outcomes, worse social functioning, and higher PG severity. The findings provide a better understanding PG heterogeneity that could be relevant to clinical management.

STEPPS for Borderline Personality Disorder: A Pragmatic Trial and Naturalistic Comparison With Noncompleters.

Systems Training for Emotional Predictability and Problem Solving (STEPPS) is a group psychotherapy approach that is effective for patients with borderline personality disorder (BPD) in a public health care setting. The sample in this study comprised 118 outpatients with BPD who were asked to participate in a Spanish-adapted version of STEPPS for 18 months, a psychotherapy program that could be added to their usual psychiatric intervention. They were divided into an experimental group who participated in STEPPS, and a control group, who received treatment as usual. Several variables were collected and the Borderline Evaluation of Severity Over Time (BEST) scale was administered at pretest, Months 3 and 6, posttest (Month 18), and 2-year follow-up (Month 42), after which a post hoc data analysis was carried out. The STEPPS program improved the as-usual treatment provided previously, and the results were cost-effective. A higher educational level and good patient collaboration predicted better outcome.

An Exploratory Analysis of Predictors of Course in Older and Younger Adults with Pathological Gambling: A Non-Treatment Sample.

We examined the association of baseline social, demographic, and clinical predictor variables with course in 48 older (≥ 60 years) and 57 younger (< 40 years) subjects with pathological gambling (PG) in a prospective follow-up study. Weekly gambling activity was tracked and used to categorize PG course. Generalized estimating equation models were used to examine predictors of disordered (i.e., level 2 or 3) gambling. Interaction tests were used to test for differential relationships for older and younger subjects. Predictors of disordered gambling during follow-up included greater severity of PG symptoms, greater severity of depressive symptoms, self-reported childhood neglect, cognitive distortions related to games of chance, and more role limitations due to physical health. Interaction tests showed that the relationships between some risk factors and disordered gambling varied for older and younger adults. Understanding these interrelationships could allow clinicians to more effectively monitor and manage their patients with PG.

Are Comorbid Disorders Associated with Changes in Gambling Activity? A Longitudinal Study of Younger and Older Subjects with DSM-IV Pathological Gambling.

This study investigates the association of comorbid disorders with gambling activity in a longitudinal follow-up study of younger and older adult subjects with DSM-IV pathological gambling (PG). The subjects included 57 younger adults with PG (≥ 18/ < 40 years) and 48 older adults with PG (≥ 60 years). Subjects were assessed at baseline and every 6 months for a mean (SD) of 31.4 (13.1) months. Comorbidity was assessed using a modification of the Longitudinal Interval Follow-up Evaluation (LIFE). During follow-up, rates of problem severity were highest for anxiety disorders, mood disorders, and impulse control disorders. Among all subjects with PG, greater severity of depression or posttraumatic stress disorder was associated with increased gambling activity. In older subjects, greater severity of agoraphobia and social phobia were associated with lowered gambling activity. In younger subjects, greater severity of any substance use disorder, an alcohol use disorder, or compulsive computer use were associated with lowered gambling activity. The latter findings provide presumptive evidence for the substitute addiction hypothesis. We conclude that increased severity of several comorbid disorders could serve as triggers for increased gambling or predict lowered gambling activity. On the other hand, certain comorbid disorders could be triggered by increased gambling activity. Knowing these interrelationships is important to gaining a better understanding of PG and its clinical management.

Attitudes of Mental Health Staff Toward Patients With Borderline Personality Disorder: An Italian Cross-Sectional Multisite Study.

Negative attitudes toward borderline personality disorder (BPD) can present a barrier to those seeking care. We explored caring attitudes toward BPD among 860 mental health professionals, including psychiatrists, psychologists, social health educators, nurses, and social workers. The results showed that social workers and nurses scored significantly lower on caring attitudes than psychiatrists, social health educators, and psychologists. Our analysis showed that the more BPD patients treated in the past year, more years of experience in mental health, and having prior BPD training were positively associated with caring attitudes scores. For all professional subgroups, except for social health educators, the caring attitudes score is higher in those who have had prior BPD training, and for professionals with low and medium level of experience in mental health. This result shows that training on BPD should target less experienced clinicians and those professional groups who had less opportunity to receive such education.

Bipolar Disorder and Suicide: a Review.

PURPOSE OF REVIEW: Bipolar disorder has the highest rate of suicide of all psychiatric conditions and is approximately 20-30 times that of the general population. The purpose of this review is to discuss findings relevant to bipolar disorder and suicide. RECENT FINDINGS: Risk factors include male gender, living alone, divorced, no children, Caucasian, younger age (< 35 years), elderly age (> 75 years), unemployment, and a personal history of suicide attempt and family history of suicide attempt or suicide completion, as well as predominant depressive polarity. Suicide is associated with the depressed or mixed subtypes, not mania. Although there are emerging treatments for bipolar depression, such as ketamine and TMS, lithium remains the only medication associated with lowered suicide rates in bipolar disorder. Understanding clinical and demographic risk factors for suicide in bipolar disorder remains the best way to prevent suicidal behavior. Early intervention and treatment with anti-suicidal medications, such as lithium, along with close observation and follow-up is the best way to mitigate suicide in patients with bipolar disorder.

A Four Marker Digital PCR Toolkit for Detecting Heavy Alcohol Consumption and the Effectiveness of Its Treatment.

Background.-Heavy alcohol consumption (HAC) is a shared concern of the forensic, medical and insurance underwriting communities. Unfortunately, there is a relative lack of clinically employable tools for detecting HAC and monitoring treatment response. Building on the results of 3 genome wide methylation studies, we have previously shown in a small group of samples that methylation sensitive digital PCR assays (MSdPCR) have the potential to accurately classify individuals with respect to HAC in a small set of individuals. Objective.-We now expand on those earlier findings using data and biomaterials from 143 participants with current HAC and 200 abstinent controls. Results.-We show that a set of 4 digital PCR assays that have a receiver operating characteristic (ROC) area under the curve (AUC) of 0.96 for detecting those with HAC. After a mean of 21 days of inpatient enforced abstinence, methylation status at one of these markers, cg04987734, began to revert to baseline values. Re-examination of methylation data from our smaller 2014 study with respect to this locus demonstrated a similarly significant reversion pattern at cg04987734 in association with treatment enforced abstinence. Conclusions.-We conclude that clinically implementable dPCR tools can sensitively detect the presence of HAC and that they show promise for monitoring alcohol treatment results. These dPCR tools could be useful to clinicians and researchers in monitoring those enrolled in substance use disorder treatment, employee wellness programs and insurance underwriting.

Religiosity and Chance Beliefs in Persons with DSM-IV Pathological Gambling Enrolled in a Longitudinal Follow-Up Study.

This study investigates the association of public, private and intrinsic religiosity and chance beliefs (superstition, illusion of control) with gambling behavior in a longitudinal follow-up study of younger and older adult subjects with DSM-IV pathological gambling (PG) and an older adult comparison group without PG. One-hundred sixty-three subjects were enrolled including 60 younger adults with PG (≥ 18/< 40 years), 53 older adults with PG (≥ 60 years), and 50 older adults without PG (≥ 60). Subjects were assessed at baseline and every 6 months thereafter. The Duke University Religion Index for Religious Assessment and the Drake Beliefs About Chance scales were administered at baseline. Follow-up was a mean (SD) of 2.6 (1.4) years. Older adults with PG scored lower on measures of public and intrinsic aspects of religiosity than older adults without PG, and scored higher on superstition and illusion of control. Older adults with PG also scored higher than younger adults with PG on private and intrinsic religiosity, but not public religiosity. Superstition predicted intrinsic, but not other aspects of religiosity. Importantly, during follow-up, higher levels of public and intrinsic religiosity were protective against problematic (levels 2, 3) gambling; were protective against chronic PG; and were predictive of PG remission status. Lower illusion of control ratings were protective against problematic gambling and chronic PG; lower superstition ratings were predictive of remission. We conclude that higher levels of public and intrinsic religiosity and lower levels of chance beliefs are associated with a more benign PG course.

Schizoaffective disorder: A review.

BACKGROUND: Schizoaffective disorder (SAD) is a chronic, potentially disabling psychotic disorder common in clinical settings. SAD often has been used as a diagnosis for individuals having an admixture of mood and psychotic symptoms whose diagnosis is uncertain. Its hallmark is the presence of symptoms of a major mood episode (either a depressive or manic episode) concurrent with symptoms characteristic of schizophrenia, such as delusions, hallucinations, or disorganized speech. METHODS: A literature search in PubMed and Google Scholar was conducted to identify articles on SAD. We also reviewed major textbooks and DSM-5 to identify pertinent information. RESULTS: This review begins with the history and classification of SAD. Debate continues to swirl around the concept, as some experts view SAD as an independent disorder, while others see SAD as either a form of schizophrenia or a mood disorder. The disorder is more common in women and its course follows the middle ground between schizophrenia and bipolar disorder. SAD appears to have high heritability. Most patients appear to benefit from antipsychotics plus antidepressants and/or mood stabilizers, depending on whether the patient has the depressive or bipolar subtype. Electroconvulsive therapy can also be effective. CONCLUSIONS: SAD is a chronic psychotic disorder that continues to be controversial. There has been inadequate research regarding its epidemiology, course, etiologic factors, and treatment.

Does response to the STEPPS program differ by sex, age, or race in offenders with borderline personality disorder?

Systems Training for Emotional Predictability and Problem Solving (STEPPS) is an evidence-based group treatment program for ambulatory patients with borderline personality disorder (BPD). The program was introduced to the Iowa correctional system in 2005, and groups have been ongoing ever since. In this analysis, we examine whether response to the STEPPS program differs based on sex, age (<40/≥40 years), or race/ethnicity (minority/non-minority) using data collected in Iowa prisons and in community corrections. Subjects were recruited and assessed by correctional staff. Offenders with BPD were offered the opportunity to participate in the STEPPS program. The presence of BPD was assessed using a module from the Structured Interview for DSM-IV Personality. Efficacy assessments included the Borderline Evaluation of Severity Over Time Scale, the Beck Depression Inventory, and the Positive and Negative Affectivity Scale. The Client Satisfaction Questionnaire-8 assessed program satisfaction. Data on 77 offenders were analyzed. All participated in the STEPPS program and 53% completed all 20 weeks. The analysis showed that there were no significant differences in response to STEPPS in terms of sex, age, or race/ethnicity on any of the three efficacy measures. Women expressed greater satisfaction than men, but there were no differences with regard to age or race/ethnicity. The implications of the findings are discussed.

STEPPS treatment programme for borderline personality disorder: Which scale items improve? An item-level analysis.

We examined which items on the Borderline Evaluation of Severity Over Time and the Zanarini Rating Scale for Borderline Personality Disorder improved during participation in Systems Training for Emotional Predictability and Problem Solving (STEPPS). Data on 193 subjects from two independent sources were included: (1) a randomized controlled trial at an academic medical centre and (2) uncontrolled data from Iowa's correctional system. STEPPS effect size was estimated by contrasting effect size for those in the randomized controlled trial assigned to STEPPS + treatment as usual to effect size for those assigned to treatment as usual alone. Items from the Borderline Evaluation of Severity Over Time scale showing the greatest improvement assessed affective instability, 'taking steps to avoid/prevent problems', 'choosing to use a positive activity', identity disturbance and abandonment fears. The Zanarini Rating Scale for Borderline Personality Disorder items showing the greatest improvement assessed mood instability, chronic feelings of emptiness and identity disturbance. STEPPS effect size was significant for the Borderline Evaluation of Severity Over Time items rating paranoia and 'taking steps to avoid/prevent problems' and the Zanarini Rating Scale for Borderline Personality Disorder items assessing paranoia, impulsivity, chronic emptiness and unstable relationships. This, and future work, could eventually help in matching patients to particular treatment programmes that target their preponderant symptoms. © 2018 John Wiley & Sons, Ltd.

Dose Response and Prediction Characteristics of a Methylation Sensitive Digital PCR Assay for Cigarette Consumption in Adults.

The tobacco use disorders are the largest preventable cause of morbidity and mortality in the world. A substantial barrier to the development of better intervention and screening measures is the lack of clinically employable biomarkers to detect the existence and extent of tobacco consumption. In prior work, we and others have shown that array based assessment of DNA methylation status at cg05575921 is a sensitive and quantitative method for assessing cigarette consumption. Unfortunately, in general, arrays are not practical clinical tools. Herein, we detail the prediction performance metrics and dose dependency of a clinically implementable droplet digital PCR (ddPCR) assay for cigarette consumption in adults. First, we demonstrate that measurements of cg05575921 as determined by Illumina array and ddPCR are highly correlated (R2 = 0.98, n = 92). Second, using clinical data and biomaterial from 177 subjects ranging from 18 to 78 years of age, we show that the Receiver Operating Characteristic (ROC) area under the curve (AUC) for classifying smoking status using methylation status at cg05575921 is 0.99. Finally, we conduct modeling analyses of cigarette consumption over discrete time periods to show that methylation status is best correlated with mean cigarette consumption over the past year (R2 = 0.5) and that demethylation at cg05575921 is dose dependent with a demethylation (delta beta) of 1% being equivalent to 1.2 cigarettes per day. But we do not find a relationship between Fagerstrom score and DNA methylation. We conclude that ddPCR assessment of cg05575921 methylation is an accurate method for assessing the presence and extent of cigarette consumption in adult subjects. We suggest that skillful clinical implementation of this approach alone or in combination with other assessment methods could lead to substantial reduction of cigarette consumption related morbidity and mortality.

A prospective follow-up study of younger and older subjects with pathological gambling.

Pathological gambling (PG) is a common and costly public health problem associated with impaired quality of life and high suicide rates. Despite its frequency in the general population, PG course is poorly understood in older adults who are especially vulnerable to its devastating consequences. We enrolled 175 subjects in a longitudinal study of gambling behavior: our case group of 53 older adults with PG (≥ 60 years), and two comparison groups including 72 younger adults with PG (< 40 years) and 50 older adults without PG (≥ 60 years). Subjects with PG met lifetime criteria for DSM-IV PG and had a South Oaks Gambling Screen (SOGS) and National Opinion Research Center DSM Screen for Gambling Problems (NODS) scores ≥ 5. Subjects were evaluated at intake and reassessed every 6 months and drop outs were replaced. Follow-up lasted a mean (SD) of 2.6 (1.4) years. At intake older PGs were more likely to be female, Caucasian, divorced, and to have a lower level of education. Older and younger PGs were similar in gambling severity, but older PGs were more likely to have sought PG treatment. Older PGs had lower rates of lifetime drug use disorders, attention deficit/hyperactivity disorder, and obsessive-compulsive disorder. They preferred slots, were more likely to receive PG treatment, and were less likely to discontinue participation in the study. Week by week gambling activity levels showed a significant general downward movement for older and younger PGs, although there were no differences between the groups. Elders without PG had no change in their level of gambling activity. We conclude that younger and older PGs moved toward a reduced level of gambling activity during follow-up. Our data challenge the notion that PG is chronic and progressive.

Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects.

Copy number variants (CNVs) have been strongly implicated in the genetic etiology of schizophrenia (SCZ). However, genome-wide investigation of the contribution of CNV to risk has been hampered by limited sample sizes. We sought to address this obstacle by applying a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls. A global enrichment of CNV burden was observed in cases (odds ratio (OR) = 1.11, P = 5.7 × 10-15), which persisted after excluding loci implicated in previous studies (OR = 1.07, P = 1.7 × 10-6). CNV burden was enriched for genes associated with synaptic function (OR = 1.68, P = 2.8 × 10-11) and neurobehavioral phenotypes in mouse (OR = 1.18, P = 7.3 × 10-5). Genome-wide significant evidence was obtained for eight loci, including 1q21.1, 2p16.3 (NRXN1), 3q29, 7q11.2, 15q13.3, distal 16p11.2, proximal 16p11.2 and 22q11.2. Suggestive support was found for eight additional candidate susceptibility and protective loci, which consisted predominantly of CNVs mediated by nonallelic homologous recombination.
