Working memory as a predictor of negative symptoms and functional outcome in first episode psychosis

The relationship of neurocognitive course with clinical and functional outcomes in psychosis is not well known, especially in the long term. The aim of the study was to examine the clinical and neuropsychological course of first-episode psychosis patients at 5-year follow-up and analyze the relationship of cognitive performance with clinical and functional outcome. The 5-year follow-up was conducted with 26 first-episode psychosis patients. Psychotic symptoms were measured by the Positive and Negative Syndrome Scale, manic and depressive symptoms by the Young Mania Rating Scale and Hamilton Depression Rating Scale respectively, and psychosocial functioning by the Functioning Assessment Short Test. The cognitive domains were assessed by the Wechsler Adult Intelligence Scale, the Wisconsin Card Sorting Test, the Trail Making Test, the Verbal Fluency Test, the Stroop Colour-Word Test and the Wechsler Memory Scale. Patients showed symptomatic improvement in the follow-up except in negative psychotic symptoms. There was also improvement in most cognitive domains except in working memory and processing speed in the follow-up. Working memory impairment was associated to negative psychotic symptoms and poor functional outcomes. Negative symptoms mediated the relationship between working memory and outcome. Therefore, negative symptoms should be a primary target of treatment to improve functional outcomes.

Predictors of pathological gambling severity taking gender differences into account

BACKGROUND

The current study aims to identify predictors of pathological gambling (PG) severity, taking gender differences into account, in an outpatient sample of pathological gamblers seeking treatment.

METHODS

The sample for this study consisted of 103 subjects (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Linear and logistic regression analyses were used to examine different risk factors (gender, age, impulsivity, sensation seeking, self-esteem) and risk markers (depression, anxiety, gambling-related thoughts, substance abuse) as predictors of PG severity.

RESULTS

Impulsivity, maladjustment in everyday life and age at gambling onset were the best predictors in the overall sample. When gender differences were taken into account, duration of gambling disorder in women and depression and impulsivity in men predicted PG severity. In turn, a high degree of severity in the South Oaks Gambling Screen score was related to older age and more familiy support in women and to low self-esteem and alcohol abuse in men. Female gamblers were older than male gamblers and started gambling later in life, but became dependent on gambling more quickly than men.

CONCLUSIONS

Further research should examine these data to tailor treatment to specific patients' needs according to sex and individual characteristics.

Schizophrenia: analysis and psychological treatment according to the clinical staging

The present paper provides an overview of the recent contributions to the study of the course of schizophrenia. This is not a disorder as chronic and as acute at its start as traditionally thought. Beyond the positive and negative symptoms and different subtypes of illness, it is important to call attention to the development and course of schizophrenia. According to this approach, the aim of this paper is to review the most recent studies on schizophrenia according to clinical stages. With this aim, we review the research carried out by leading research teams and recently published clinical practice guidelines (Birmingham Group, Melbourne Group, GPCSNS, NICE) in relation to the course, the main features, and more adjusted treatment alternatives, aimed to improve the characteristic symptoms of each stage of the disease. Finally, we point out the necessity to integrate this approach with the proposed changes for the upcoming DSM-V. This review identifies effective treatment options for each of the phases of the disease defined by the clinical stage approach.

Predictors of good outcome in patients with refractory bipolar disorder after a drug or a drug and cognitive-behavioral treatment

OBJECTIVE

The objective of the present research study was to analyze the variables involved in the favorable prognosis of patients with refractory bipolar disorder after a drug or a drug and cognitive-behavioral treatment.

METHODS

A sample of 40 patients was divided into 2 groups: (1) combined drug plus psychoeducational and cognitive-behavioral treatment or (2) drug treatment only (control group). We used a multigroup design with repeated measures at different times (baseline, posttreatment, 6-month follow-up, and 12-month follow-up) to evaluate the following variables: age, sex, number of hospitalizations, type of treatment, mania (Young Mania Rating Scale, or YMRS) and depression (Beck Depression Index, or BDI) symptoms, subsyndromal symptoms (BDI >7; YMRS >6), global suffering index, general index of social ability, self-esteem (Rosenberg scale), inadaptation (inadaptation Scale), anxiety (State-Trait Anxiety Inventory), quality of life (Global Activity Functioning), and health (European Quality of Life Scale). We considered favorable prognosis for subjects without persistent affective symptoms (BDI <7; YMRS <6) and/or without relevant difficulties in adaptation (Inadaptation Scale <14) in a 12-month follow-up.

RESULTS

A binary logistic regression showed that the type of treatment (combined therapy corresponded to better progression), the number of prior hospitalizations (fewer hospitalizations corresponded to better progression), and self-esteem (higher self-esteem corresponded to better prognosis) were statistically significant.

CONCLUSIONS

The type of treatment, the number of prior hospitalizations, and the level of self-esteem were the most influencing factors for a favorable progression of refractory bipolar disorder. Differently from other studies, no significant influences of age, sex, subsyndromal symptoms, anxiety, and depression symptoms on the prognosis of refractory bipolar disorder were observed in our study.

One-year psychosocial functioning in patients in the early vs. late stage of bipolar disorder

OBJECTIVE

The aim of this 1-year follow-up study was to compare functional outcome as well as clinical differences between patients with first- and multiple-episode bipolar disorder.

METHOD

Bipolar disorder patients with first (n = 60) and multiple episodes (n = 59) were recruited from two hospitals in Spain. The Functioning Assessment Short Test (FAST) was used to assess functioning. The Hamilton Depression Rating Scale (HAMD) and the Young Mania Rating Scale (YMRS) were administered to assess mood symptoms.

RESULTS

As expected, patients with first episode experienced a greater functioning compared to patients with multiple episodes (11.26 ± 10.94 vs. 26.91 ± 13.96; t = 6.436, P < 0.001). There were significant demographic and clinical differences between both groups. Baseline depressive symptoms (F = 9.553, df = 4, 102; P < 0.001) and age (F = 14.145, df = 4, 103; P < 0.001) were significantly associated with poor functional recovery at 6-month and 12-month assessment, respectively, in a group of patients with multiple episodes.

CONCLUSION

Our data give support to the model of staging in bipolar disorder, showing that the enduring neurotoxicity of repeated episodes may contribute to sustained impairment in multiple areas of psychosocial functioning.

[Psychometric properties of the Conflict Tactics Scales (CTS-2) in a Spanish sample of partner-violent men]

Intimate partner violence is a complex problem that requires the update of the available assessment tools. The aim of the study is to test the revised Conflict Tactics Scales (CTS-2) in partner-violent men. Its structure and other psychometric properties are analyzed in 173 convicted offenders from Brians-2 and Alhaurín de la Torre penitentiaries. Discriminant validity is also assessed by comparing offenders with 108 males from the general population. The internal consistency for the 39 items of perpetration is .88 (varying from .59 to .83 among the subscales). The validity data indicate that the scale is useful to discriminate between batterers and general population in physical and psychological violence, although there is an overlap between different types of violence, and it is difficult to compare self-reports with external criteria such court decisions. The results of confirmatory factorial analysis do not support the original five-factor structure. Using exploratory factorial analysis, four components with good internal consistency were identified: Physical (.86), Sexual (.75), and Psychological Violence (.82), and Negotiation (.83). Recommendations for use and a reference guide of rating scores in samples of offenders are suggested.

[Does really sex addiction exist?]

Hypersexual Disorder has been proposed as a new psychiatric disorder for DSM-V, characterized by an increased frequency and intensity of sexually motivated fantasies, arousal, urges, and enacted behavior in association with an impulsivity component. Excessive appetitive and consummatory behaviors, including hypersexuality, can become a non-chemical addiction. Sexual addiction afflicts people having paraphilic or nonparaphilic behaviors associated with progressive risk-taking sexual behaviors, escalation or progression of sexual behaviors (tolerance), loss of control and significant adverse psychosocial consequences, such as unplanned pregnancy, pair-bond dysfunction, marital separation, financial problems and sexually transmitted diseases including HIV. The most common behaviors involved in sexual addiction are fantasy sex, compulsive masturbation, pornography, cybersex, voyeuristic sex, anonymous sex and multiple sexual partners. These behaviors are intended to reduce anxiety and other dysphoric affects (e.g., shame and depression). Axis I psychiatric diagnosis, especially mood disorders, psychoactive substance abuse disorders and attention deficit hyperactivity disorders, are common comorbid disorders with sexual addiction. There are significant gaps in the current scientific knowledge base regarding the clinical course, development risk factors and family history and data on women with sexual addiction are lacking.

Clinical gender differences among adult pathological gamblers seeking treatment

This study aimed to examine the gender-related differences in demographics, gambling measures, psychological functioning, and motivation for therapy in an outpatient sample of pathological gamblers seeking treatment. Participants in this multisite study included 103 adult outpatients (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Logistic regression was used to examine if gender was related together to categorical and continuous independent variables. Female gamblers were older than men and more likely to be divorced or widowed and to have a lower annual income. Women became more dependent on bingo and men on slot machines. Gambling motivation and the course of illness for both sexes were also different. Female gamblers were more anxious and with a poorer self-esteem than male gamblers and more affected by depressive symptoms; in turn, men were more impulsive and higher sensation seekers than women and more affected by drug/alcohol abuse. The 68.6% of female gamblers reported being victims of intimate partner violence. There were no gender differences about the motivation for treatment. Future research should examine gambling behaviors and psychological functioning and suggest treatment approaches to address specific goals according to these gender-related differences.

[Web of Science production quality indicators of ten professors' at the area of personality, assessment and psychological treatment: additional contributions to Olivas-Ávila y Musi-Lechuga study]

Rankings of scientific productivity are increasingly relevant both from an individual and a collective perspective. Therefore, making sure they are based on reliable and exhaustive information is really important. This study clearly shows that available rankings change dramatically when internationally acknowledged bibliometric indices are considered. Data from the 10 Professors belonging to the 'Personality, Assessment, and Psychological Treatment' Department considered in the recent analysis by Olivas-Ávila y Musi-Lechuga ( Psicothema 2010. Vol. 22, nº 4, pp. 909-916) are revisited here for illustrative purposes.

New criteria for personality disorders in DSM-V

Diagnosing disorders in the current edition of the DSMIV involves two aspects. The first is the concept of a personality disorder, which currently is defined as a pervasive, stable and presents at least from adolescence pattern of "inner experience and behavior" that is deviant from a person's cultural norms. The second aspect involves defining what type of personality disorder is present among a list of ten, with a catch-all "not otherwise specified category". There are many problems with the existing system: the different personality types are poorly defined and the diagnostic criteria overlap heavily. The proposed revision on the DSM-V website appears quite complicated and has three major facets: a new definition for personality disorder, focused on "adaptive failure" involving "impaired sense of self-identity" or "failure to develop effective interpersonal functioning"; five personality types (Antisocial/Psychopathic, Avoidant, Borderline, Obsessive-Compulsive, and Schizotypal); and a series of six personality "trait domains", each of them with a subset of facets. This new proposed system for personality disorder diagnosis may be controversial. Finally challenges for the next future are discussed.

[Severe intimate partner violence risk prediction scale-revised]

The aim of this study was to describe the psychometric properties of the Severe Intimate Partner Violence Risk Prediction Scale and to revise it in order to ponderate the 20 items according to their discriminant capacity and to solve the missing item problem. The sample for this study consisted of 450 male batterers who were reported to the police station. The victims were classified as high-risk (18.2%), moderate-risk (45.8%) and low-risk (36%), depending on the cutoff scores in the original scale. Internal consistency (Cronbach's alpha=.72) and interrater reliability (r=.73) were acceptable. The point biserial correlation coefficient between each item and the corrected total score of the 20-item scale was calculated to determine the most discriminative items, which were associated with the context of intimate partner violence in the last month, with the male batterer's profile and with the victim's vulnerability. A revised scale (EPV-R) with new cutoff scores and indications on how to deal with the missing items were proposed in accordance with these results. This easy-to-use tool appears to be suitable to the requirements of criminal justice professionals and is intended for use in safety planning. Implications of these results for further research are discussed.

How effective is a psychological intervention program for patients with refractory bipolar disorder? A randomized controlled trial

BACKGROUND

The aim of this research was to evaluate the short-term and long-term efficacy of a combined treatment (pharmacological + psychoeducational and cognitive-behavioral therapy) as compared with a standard pharmacological treatment in patients with refractory bipolar disorder.

METHOD

40 patients were randomly assigned to one of the following: Experimental group under combined treatment, and Control group under pharmacological treatment. We used an analysis of variance (ANOVA), including one or two factors, with repeated measures at different evaluation times: baseline, post-treatment, 6-month follow-up and 12-month follow-up.

RESULTS

We found significant between-group differences at all evaluation times after the treatment. The experimental group showed less hospitalizations than the control group in the 12-month evaluation (p=0.007) as well as lower rates of depression and anxiety in the 6-month valuation (p=0.015; p=0.027) and the 12-month evaluation (p=0.001; p<0.001). Significant differences in relation to mania and inadaptation emerged in the post-treatment evaluation (p=0.004; p<0.001) and were sustained throughout the study (p=0.002, p<0.001; p<0.001, p<0.001). Analysis of within-group differences in the Experimental group showed reduction of mania (p<0.001), depression (p=0.001), anxiety (p=0.003) and inadaptation (p<0.001) throughout the study; while in the Control group, it showed increased numbers of hospitalizations (p=0.016), as well as higher rates of mania (p=0.030), anxiety (p<0.001) and inadaptation (p=0.003).

CONCLUSIONS

Our results suggest that a combined treatment is effective in patients with refractory bipolar disorder. Suggestions for future research are commented on.

Violence and personality disorders: clinical and forensic implications

Several studies have provided strong evidence that personality disorders (PD) represent a significant clinical risk for violence. This review has aimed to examine the relationship of greater risk for violence among persons with certain PD in terms of four fundamental personality dimensions: 1) impulse control; 2) affect regulation; 3) threatened egotism or narcissism; and 4) paranoid cognitive personality style. Two of these dimensions -impulse control and affect regulation- are probably substantially affected by virtually all PDs linked to violence. Narcissism or threatened egotism and paranoid cognitive personality style have also been empirically linked to violence and mental disorder. PD symptoms have proven to be even stronger predictors of violence than the PDs per se. In fact, increased symptoms of DSM-IV cluster A or cluster B PD, such as paranoid, narcissistic and antisocial PD symptoms, correlate significantly with violence. Finally, there are three important principles about the relationship between PDs and violence: 1) PDs are rarely egosyntonic; 2) most patients and violent situations that come to clinical attention involve comorbid conditions; and 3) violence and risk of violence are often associated with substance abuse. Implications of this review for further research are discussed.

[Violence risk assessment: Available tools and instructions for use]

Violence management and prevention exceed the exclusive court intervention and require other professionals, such as psychologists, who can help in specialized tasks like dangerousness assessment and violence recidivism control. The latest improvements in the prevention of violence have proposed the replacement of dangerousness assessment for the violence risk assessment. This new technology is more efficient to predict the future violent behavior. In this study, we present the basis of these techniques for the violence risk assessment, as well as the Spanish adapted tools and instruments for its application in clinical, forensic and correctional psychology. These are, briefly described, the VRAG scale, the PCL-R, the HCR-20, the SCR-20, the SARA test, the EPV and the SAVRY, as well as their specific functions and applications.
