RESUMO

The aim of the present study was to examine the differences in sociodemographic and clinical characteristics of 104 women diagnosed with compulsive buying behaviour (CBB = 55) or gambling disorder (GD = 49) treated at three public hospitals unit specialized in behavioural addictions from January 2004 to December 2015. Significant between-group differences in sociodemographic variables were observed for cohabitation status (living with a partner or not) and educational level, with a higher percentage of women in the GD group cohabiting (х2 (1), p = .029). By contrast, the CBB group had a significantly higher educational level (х2 (1) = 7.4, p = .007). There were no significant differences between the groups in age of onset, age at treatment initiation, age at the onset of behavioural problems, or in the years elapsed until presenting addiction problems. However, there were significant between-group differences in the amount of money spent weekly (F (1.100) = 4.9, p = .028), with women in the CBB group spending on average €289.4/week (SD, 412.4) versus €151/week (SD, 141.23) in the GD group. The CBB group had significantly more depressive disorders compared to the GD group (х2(1) = 5.4, p = .020). In contrast, the GD group presented significantly more tobacco use than the CBB group (х2(1) = 1.19, p = .000). This study suggests that women with CBB or GD share more characteristics than differences and the treatment approaches must take into account gender related factors.

RESUMO

Women with schizophrenia have shown better social and clinical functioning than men in several previous studies. The aim of this study was to assess gender differences in social functioning of people with a diagnosis of schizophrenia who are in psychosocial rehabilitation treatment in Catalonia, using several different one-dimensional and multidimensional measures of clinical and social functioning. Gender differences were found only in several daily life activities, in which women showed better functioning: independence-competence (p = 0.006) and independence-performance (p = 0.017). No other differences between genders were observed. Our results clearly suggest that women with schizophrenia undergoing the rehabilitation process could benefit as do men from psychosocial intervention in order to improve social skills and functioning.

RESUMO

OBJECTIVE: Although little is known about neurocognition in Dual Diagnosis, it has been suggested that Schizophrenia (SZ) patients with comorbid substance use belong to a subgroup with lower genetic vulnerability to develop SZ and, consequently, they show better executive and social premorbid functioning. The first aim of this study was to assess the executive functioning, and the second one was to explore the effect of age of onset of substance use in neurocognition in SZ patients with cocaine dependence. METHODS: The total sample consisted of 95 male patients, aged 20 to 60 years, divided in three groups: one group with SZ and cocaine dependence (SZ+; n = 30), another group with SZ without cocaine dependence (SZ-; n = 30), and a control group with cocaine dependence without psychiatric comorbidity (COC; n = 35). RESULTS: We found a better executive functioning in both SZ+ and COC than SZ-. We observed a worse performance of SZ+ patients compared with COC in cognitive set-shifting regardless the age of onset of consumption. CONCLUSIONS: The results agree with the hypothesis of a lower genetic vulnerability in SZ+ patients to develop psychosis compared with SZ-, who develop it without any additional trigger. However, future research is needed to clarify the current knowledge gaps.

RESUMO

BACKGROUND AND OBJECTIVES: Attention deficit hyperactivity disorder (ADHD) is highly prevalent among drug abusers. We studied the psychiatric comorbidity and characteristics of cocaine use in relation to the presence of ADHD among patients with cocaine dependence. METHODS: A total of 200 cocaine-dependent patients attending an Outpatient Drug Clinic participated in the study. A systematic evaluation of ADHD (CAADID-II), the severity of addiction (EuropASI) and other axes I and II psychiatric disorders was made (SCID-I and SCID-II). A descriptive, bivariate, and multivariate analysis of the data was performed. RESULTS: In the multivariate analysis, the identified risk factors for the development of ADHD were a history of behavioral disorder in childhood (OR: 3.04), a lifetime history of cannabis dependence in the course of life (OR: 2.68), and age at the start of treatment (OR: 1.08). The bivariate analysis showed ADHD to be associated with other factors such as male gender, age at start of cocaine use and dependence, the amount of cocaine consumed weekly, increased occupational alteration, alcohol consumption, general psychological discomfort, depressive disorder, and antisocial personality disorder. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: We conclude that ADHD is associated with increased psychiatric comorbidity and greater severity of addiction.

RESUMO

BACKGROUND: Although the studies published so far have found an affectation in the Health Related Quality of Life (HRQOL) in both psychiatric and substance use dependence disorders, very few studies have applied HRQOL as an assessment measure in patients suffering both comorbid conditions, or Dual Diagnosis. The aim of the current study was to assess HRQOL in a group of patients with Dual Diagnosis compared to two other non-comorbid groups and to determine what clinical factors are related to HRQOL. METHODS: Cross-sectional assessment of three experimental groups was made through the Short Form - 36 Item Health Survey (SF-36). The sample consisted of a group with Dual Diagnosis (DD; N = 35), one with Severe Mental Illness alone (SMI; N = 35) and another one with Substance Use Dependence alone (SUD; N = 35). The sample was composed only by males. To assess the clinical correlates of SF-36 HRQOL, lineal regression analyses were carried out. RESULTS: The DD group showed lower scores in most of the subscales, and in the mental health domain. The group with SUD showed in general a better state in the HRQOL while the group with SMI held an intermediate position with respect to the other two groups. Daily medication, suicidal attempts and daily number of coffees were significantly associated to HRQOL, especially in the DD group. CONCLUSIONS: The DD group showed lower self-reported mental health quality of life. Assessment of HRQOL in dual patients allows to identify specific needs in this population, and may help to establish therapeutic goals to improve interventions.

RESUMO

INTRODUCTION: The aim of the present study was to assess the relationship between social functioning and clinical symptoms in people with schizophrenia, analyzing the influence of both global social functioning and the specific aspects of social functioning, assertiveness and communication skills in the explanation of type of symptoms. MATERIAL AND METHODS: A cross-sectional descriptive study composed of 125 people diagnosed with schizophrenia was performed. Patients were assessed with the Communication Skills Questionnaire (CSQ), the Gambrill and Richey Assertiveness Inventory (GR), the Global Assessment of Functioning Scale (GAF) and the Global Assessment of Social Functioning Scale (SOFAS), Social Functioning Scale (SFS), Life Skills Profile (LSP) scale and the Clinical Global Impression scale for Schizophrenia (CGI-S). RESULTS: SOFAS, LSP and GR are related to each of the subscales and total scores of symptoms (p<0.05-0.001). The multiple regressions show that SOFAS and GR explained 59% of the total symptoms. SOFAS and GR, accounting for 65% of the variance, explain positive symptoms. GR and SOFAS explained 34% of the variance of negative symptoms. SOFAS, CSQ and LSP, accounting for 20% of the variance, explain depressive symptoms. SOFAS explained 46% of the variance of cognitive symptoms. CONCLUSIONS: Our findings suggest the usefulness of social functioning assessment in the explanation of clinical symptoms in people with schizophrenia. Moreover, our results point out that not only negative and cognitive symptoms, but also positive and depressive symptoms, should be taken into account in the rehabilitation process in order to improve patient adaptation in the community.

RESUMO

Premorbid functioning has been related with several clinical features and prognosis of schizophrenia spectrum disorders. Comorbidity with substance use is highly prevalent and usually hinders clinical improvement in this kind of psychiatric disorders. This systematic review analyzes the differences in the premorbid functioning of subjects with a schizophrenia spectrum disorder with substance use (SSD+, dual psychosis) or without it (SSD-). A systematic review (PRISMA guidelines), including search in electronic databases (MEDLINE, Web of Science, and Cochrane Library), was performed. 118 published works were considered of which only 20 met our inclusion criteria. Although there is a great variability in methodologies, diagnoses included, and substances used, studies using the Premorbid Functioning Scale to assess the academic and/or social domains found that SSD+ subjects had a poorer academic but better social premorbid functioning than those with SSD-. Current evidence is not conclusive, so additional studies are required to integrate intervening factors in order to clarify the clinical implications of premorbid functioning to improve the course and therapeutic response of patients.

RESUMO

The objective of the study was to test the usability of 'Feeling Master' as a psychotherapeutic interactive gaming tool with LEGO cartoon faces showing the five basic emotions, for the assessment of emotional recognition in people with schizophrenia in comparison with healthy controls, and the relationship between face affect recognition (FER), attributional style, and theory of mind (ToM), which is the ability to understand the potential mental states and intentions of others. Nineteen individuals with schizophrenia (SZ) and 17 healthy control (HC) subjects completed the 'Feeling Master' that includes five basic emotions. To assess social cognition, the group with schizophrenia was evaluated with the Personal and Situational Attribution Questionnaire (IPSAQ) for the assessment of attributional style and the Hinting Task (ToM). Patients with SZ showed significant impairments in emotion recognition and their response time appeared to be slower than the HC in the recognition of each emotion. Taking into account the impairment in the recognition of each emotion, we only found a trend toward significance in error rates on fear recognition. The correlations between correct response on the 'Feeling Master' and the hinting task appeared to be significant in the correlation of surprise and theory of mind. In conclusion, this study demonstrated that the 'Feeling Master' could be useful for the evaluation of FER in people with schizophrenia. These results sustain the notion that impairments in emotion recognition are more prevalent in people with schizophrenia and that these are related with impairment in ToM.

RESUMO

INTRODUCTION AND PURPOSE: The purpose was to analyze socioeconomic and clinical factors of psychosocial functioning and self-perception in relation to health-related quality of life (HRQOL) in people with severe mental health illness (SMI) by gender. MATERIALS AND METHOD: A cross-sectional study was conducted on a sample of 133 women and 90 men. Recorded variables: HRQOL, SF-36 Physical Component Scores (PCS) and Mental Component Scores (MCS); sociodemographic and clinical data on psychosocial and self-perception functioning. Correlational studies using raw and adjusted linear regression models to evaluate the factors associated with HRQOL by obtaining coefficients, p-values and respective confidence intervals. RESULTS: The mean PCS for women and men was 44.6 and 49.0 (p = 0.004) and 36.4 and 37.5 (p = 0.575), respectively for MCS. The factors associated with PCS in women were age, -0.2(-0.4:0); in work, 4.2(0.3:8.2); with an income higher than 700 euros/month, 4.4(1:7.7). In men, these factors were education level, 6.1(0.4:11.7); belief that they would not need help in the future, 4.6(0.1:9.2) and a higher need for psychosocial services, -6.6(-11.1:-2). Factors associated with MCS in women were, in work, 6.1(1.5:10.7); and having a high number of friends, 6.6(2.1:11.1). In men, these factors were, living alone, -7.1(-12.7:-1.4); lack of economic benefits, 8.5(3.2:13.8); and a higher need for psychosocial and social services, -3.6(-7.1:-0.2) and -7.7(-13.4:-2). CONCLUSIONS: The dimensions affected and the factors that are associated with HRQOL for people with SMI differ by gender. Therefore, these differences should to be taken into account when designing interventions for improving HRQOL.

RESUMO

Personality traits are relevant in understanding substance use disorders (SUD) and schizophrenia (SZ), but few works have also included patients with dual schizophrenia (SZ+) and personality traits. We explored personality profile in a sample of 165 male patients under treatment, using the Temperament and Character Inventory-Revised. The participants were assigned to three groups of 55 patients each, according to previous diagnosis: SUD, SZ- and SZ+ (without/with SUD). We analyzed their clinical characteristics, relating them to personality dimensions. The SUD and SZ+ groups scored higher than SZ- in Novelty/Sensation Seeking. SZ- and SZ+ presented higher Harm Avoidance and lower Persistence than the SUD group. SZ+ patients showed the lowest levels of Self-directedness, while SZ- and SZ+ had higher scores in Self-transcendence than the SUD group. Several clinical characteristics were associated with personality dimensions depending on diagnosis, and remarkably so for psychiatric symptoms in the SZ- and SZ+ groups. The three groups had a maladaptive personality profile compared to general population. Our results point to different profiles for SUD versus SZ, while both profiles appear combined in the SZ+ group, with extreme scores in some traits. Thus, considering personality endophenotypes in SZ+ could help in designing individualized interventions for this group.

RESUMO

OBJECTIVE: To describe the hangover phenomenon and briefly review its main explanatory factors. DESIGN: Bibliographic research on main databases (Medline and Psychinfo). RESULTS: Alcohol hangover is characterized by adverse physical and mental effects that occur the next morning after the intake of toxic doses of alcohol. This phenomenon is a very frequent experience among alcohol-consuming people and it has been associated to high socio-economic costs, mainly due to absenteeism and poor performance in academic and work settings. Multiple theories exist to explain the appearance and severity of hangover, such as direct or indirect effects of alcohol, alcohol withdrawal, and toxic effects of alcoholic beverage congeners or of alcohol metabolites. In addition, a number of intervening factors have been identified, such as vulnerability to alcohol dependence or psychological factors. CONCLUSIONS: Although several studies analyze and describe hangover, it is still poorly understood. Further well-designed studies with a unitary methodology and clear operational criteria to define hangover are necessary in order to clarify such a phenomenon. We suggest some future working ideas that should be pursued in order to address the current shortcomings.

RESUMO

OBJECTIVE: To adapt and to validate the Experience of Caregiving Inventory (ECI) in a Spanish population, providing empirical evidence of its internal consistency, internal structure and validity. METHOD: Psychometric validation of the adapted version of the ECI. One hundred and seventy-two caregivers (69.2% women), mean age 57.51 years (range: 21-89) participated. Demographic and clinical data, standardized measures (ECI, suffering scale of SCL-90-R, Zarit burden scale) were used. The two scales of negative evaluation of the ECI most related to serious mental disorders (disruptive behaviours [DB] and negative symptoms [NS]) and the two scales of positive appreciation (positive personal experiences [PPE], and good aspects of the relationship [GAR]) were analyzed. Exploratory structural equation modelling was used to analyze the internal structure. The relationship between the ECI scales and the SCL-90-R and Zarit scores was also studied. RESULTS: The four-factor model presented a good fit. Cronbach's alpha (DB: 0.873; NS: 0.825; PPE: 0.720; GAR: 0.578) showed a higher homogeneity in the negative scales. The SCL-90-R scores correlated with the negative ECI scales, and none of the ECI scales correlated with the Zarit scale. CONCLUSIONS: The Spanish version of the ECI can be considered a valid, reliable, understandable and feasible self-report measure for its administration in the health and community context.

RESUMO

Coping strategies have an impact on substance use disorders (SUD), relapses, and clinical variables, but knowledge on this area is scarce. We explored the coping strategies used during treatment in patients with dual diagnosis (DD), SUD, and severe mental illness (SMI), and the relation with clinical course and relapses at one-year follow-up. A sample of 223 patients was divided into three groups depending on diagnosis: DD (N = 80; SUD with comorbid schizophrenia or major depressive disorder), SUD only (N = 80), and SMI only (N = 63; schizophrenia or major depressive disorder). MANCOVA analyses reflected differences in self-criticism and problem avoidance, with a higher use of these in the DD and SUD groups. The coping strategies used differed depending on the presence/absence of a SUD, but not depending on psychiatric diagnosis. At one-year follow-up, social support was the only strategy that predicted the presence of relapses in DD patients with schizophrenia (positively), and in SMI patients with major depressive disorder (negatively). Thus, social support was associated with relapses, but the relationship was different depending on psychiatric diagnosis. Further studies should analyze the implications of social support as a coping strategy in different mental disorders, as well as its usefulness in individualized interventions.

RESUMO

OBJECTIVES: Some previous studies have demonstrated an early effect of caffeine administration on subjective state, but none of them has explored its existence after the administration of decaffeinated coffee, or the possible differences depending on the gender and circadian typology of the subjects. The aim of the present work is to investigate the early effects (10-30 min post-consumption) of a single low dose of caffeine (100 mg) and decaffeinated coffee on sleepiness, subjective activation and affect using a realistic design. The influence of gender and circadian typology is also explored. METHODS: A randomized double-blind informed placebo controlled procedure was applied to 688 healthy undergraduate volunteers, mean age 22.03+/-2.21 years, 238 men and 450 women. Measures were recorded before and after beverage consumption (10, 20 and 30 min), in two experimental sessions: morning 11:00-13:00 h or afternoon 16:00-18:00 h. RESULTS: Caffeine administration induced arousing effects (lesser somnolence and greater activation) in all post-consumption records, while the effects of decaffeinated drink were only apparent at 10 min. Caffeine effects were greater in men, and the decaffeinated beverage produced greater effects in women. Circadian typology only showed effects for time of day (morning/afternoon) related with rhythmic expression. CONCLUSION: Future works should study more accurately the early effect of coffee beverages and the influence of gender, using other parameters which have proven to be sensitive to their administration. The effect of several caffeine doses should also be studied.

RESUMO

Alcohol hangover is characterized by adverse physical and mental effects that occur the next morning after the intake of toxic doses of alcohol. One of the more relevant functional consequences of hangover is the cognitive and subjective impairment, which could be related to the high socioeconomic costs of alcohol consumption. Nevertheless, few studies have addressed the study of neurocognitive and subjective effects of hangover. The systematic and exhaustive study of neurocognitive and subjective effects has not been done. In the present work we briefly review the hangover impact, not only in the objective execution of attention, psychomotricity and memory tasks, but in the subjective state of the subjects as well. Moreover, we also highlight the methodology difficulties to study neurocognitive effects of hangover and suggest several aspects to take into account in future investigations.

RESUMO

Background: Among patients with substance use disorder (SUD), major depressive disorder (MDD) is highly prevalent. Even though, personality plays an important role in treatment outcomes for individuals with SUD and SUD + MDD, few studies have explored personality characteristics in these samples. This study aims to describe personality for patients with SUD taking into account the comorbid MDD, using the Alternative Five Factor Model (AFFM). We also aim to compare SUD + MDD patients with population norms and to elucidate possible personality clinical correlates. Methods: For our study, 116 male patients undergoing for SUD treatment were divided in two groups: SUD only (N = 58) and SUD + MDD (N = 58). To examine personality, we used the Zuckerman-Kuhlman Personality Questionnaire and multiple analyses of covariance were performed to identify differences. In a first analysis, age was introduced as a covariate whereas in a second analysis the continuous variables that showed to have a discriminant value for the groups were added as covariates. Variables predicting the presence of dual diagnosis and personality clinical correlates were analyzed by logistic and linear regression models, respectively. We observed that patients with SUD + MDD show distinctive personality characteristics compared with patients with SUD only and population norms. Results: According to the AFFM, SUD + MDD patients are characterized by higher Neuroticism-Anxiety (positively associated to depressive symptoms) and Impulsivity; and by lower Parties and Friends. Moreover, the probability of having a dual depressive disorder was represented by the amount of medications and substances used. The preference for hard work and the energy self-reported levels (Work Activity trait) are linked to these clinical variables rather than to the presence/absence of a dual depressive disorder. Conclusions: Even when controlling clinical variables related to a higher probability of having a dual depressive disorder, the Neuroticism-Anxiety is a personality trait that strongly differentiates between SUD only and SUD + MDD patients. Further investigation is needed to explore the role of this personality trait as endophenotype in dual depressive men. Our results underline the importance of a dimensional understanding of personality and its clinical correlates among patients with SUD + MDD; this approach could provide us information on specific treatment strategies to improve the prognosis of patients.

RESUMO

Soil passage of (pretreated) surface water to remove pathogenic microorganisms is a highly efficient process under oxic conditions, reducing microorganism concentrations about 8 log10 within tens of meters. However, under anoxic conditions, it has been shown that removal of microorganisms can be limited very much. Setback distances for adequate protection of natural groundwater may, therefore, be too short if anoxic conditions apply. Because removal of microorganisms under suboxic conditions is unknown, this research investigated removal of bacteriophage MS2 and PRD1 by soil passage under suboxic conditions at field scale. At the field location (dune area), one injection well and six monitoring wells were installed at different depths along three suboxic flow lines, where oxygen concentrations ranged from 0.4 to 1.7 mg/l and nitrate concentrations ranged from 13 to 16 mg/L. PRD1 and MS2 were injected directly at the corresponding depths and their removal in each flow line was determined. The highest bacteriophage removal was observed in the top layer, with about 9 log removal of MS2, and 7 log removal of PRD1 after 16 meters of aquifer transport. Less removal was observed at 12 m below surface, probably due to a higher groundwater velocity in this coarser grained layer. MS2 was removed more effectively than PRD1 under all conditions. Due to short travel times, inactivation of the phages was limited and the reported log removal was mainly associated with attachment of phages to the aquifer matrix. This study shows that attachment of MS2 and PRD1 is similar for oxic and suboxic sandy aquifers, and, therefore, setback distances used for sandy aquifers under oxic and suboxic conditions provide a similar level of safety. Sticking efficiency and the attachment rate coefficient, as measures for virus attachment, were evaluated as a function of the physico-chemical conditions.

RESUMO

Recently there is a growing interest in the interaction of schizophrenia spectrum disorders (SSD) and substance use disorders (SUD), a condition named dual schizophrenia spectrum disorders (SSD+). While previous research has focused on clinical and cognitive aspects, little is known about the impact of comorbidity in the brain structure and functions. Evidence suggests that dual diagnosis patients, including SSD+, show a better neurocognitive functioning during the first years of illness, followed by a serious long-term decline. The initial search retrieved 94 articles, 12 were excluded for being redundant and 49 for not fulfilling the selection criteria. Thirty-three structural and functional neuroimaging studies that compare SSD and SSD+ patients were included. Both groups exhibited more brain alterations, in comparison to only SUD patients and healthy controls. SSD+ patients are less cognitively and emotionally impaired than non-dual SSD, but worse than healthy controls. The neurobiological alterations are prominent in SSD+ after five years of illness or longer. Moreover, SUD characteristics are important modulating factors, contrary to clinical severity or specific SSD diagnosis.

RESUMO

BACKGROUND: Lifetime suicide attempts in patients with comorbidity between psychotic disorders and Substance Use Disorder (SUD), known as dual diagnosis, was associated with a worse clinical and cognitive state, poor prognosis and premature death. However, to date no previous study has examined the cognitive performance of these patients considering as independent the presence or absence of lifetime suicide attempts. METHODS: We explore executive functioning differences between suicide attempters and non-attempters in dual schizophrenia (DS) patients and the possible related factors for both executive performance and current suicide risk. Fifty DS male patients in remission of SUD and clinically stables, 24 with and 26 without lifetime suicide attempts, were evaluated. We considered Z scores for all neuropsychological tests and a composite summary score for both premorbid IQ and executive functioning. RESULTS: DS patients showed low performance in set-shifting, planning and problem solving tasks. Those with suicide attempts presented lower composite summary scores, together with worse problem solving skills and decision-making, compared with non-attempters. However, after controlling for alcohol dependence, only differences in decision-making remained. Executive functioning was related to the premorbid intelligence quotient, and several clinical variables (duration, severity, months of abstinence and relapses of SUD, global functioning and negative symptoms). A relationship between current suicide risk, and first-degree relatives with SUD, insight and positive symptoms was also found. CONCLUSIONS: Our results suggest that problem solving and, especially, decision-making tasks might be sensitive to cognitive impairment of DS patients related to presence of lifetime suicide attempts. The assessment of these executive functions and cognitive remediation therapy when necessary could be beneficial for the effectiveness of treatment in patients with DS. However, further research is needed to expand our findings and overcome some limitations of this study.
