Network and Exploratory Factorial Analysis of the Depression Clinical Evaluation Test

Depression is a highly prevalent disorder with a wide range of symptomatology. Existing instruments for its assessment have only a few items for each factor. The Depression Clinical Evaluation Test (DCET) has been created to cover all depression symptoms at different times (month, year, and always) with several items for each facet. The content validity of this instrument has been judged by experts and, in this paper, we analyse its factorial structure and make a network analysis of it. The test (196 items) was administered to 602 adults without psychological disorders (M_age = 24.7, SD = 8.38, 72% women) both online and on paper. A network was estimated for each time point, using the absolute minimum selection and shrinkage operator. From the factor analysis, 12 factors were established for month, 11 for year, and 10 for always, leaving 94 items. The network analysis showed that the facets of depressive mood, anhedonia, and thoughts of Death, are central to all the estimated networks. The DCET is proposed as a valid and reliable multifactorial instrument to detect the variability of depressive symptoms in adults, guaranteeing its diagnostic usefulness.

Content Validity through Expert Judgment for the Depression Clinical Evaluation Test

Background/Objective

The evaluation of depression requires valid and reliable measuring instruments, which collect a wide spectrum of symptoms that this disorder displays, in order to carry out an accurate and differential diagnosis. The objective of this work is the construction of the Depression Clinical Evaluation Test (DCET), where affective, somatic, cognitive, behavioral and interpersonal symptoms are considered and also analyze its content validity through an expert judgment.

Method

Based on different diagnostic and manual classifications, a specification table for a depression test was established. In its evaluation, 16 experts in Psychological Assessment, Psychometry and/or Psychopathology participated. A total of 300 items were created. The experts had to assess the items according to the criteria of Content, Relevance, Clarity, Comprehension, Sensitivity, and Offensiveness. In addition, 50 adults, evaluated the compression of the items.

Results

The degree of understanding for all the items was high and the expert judgment favoured the suppression of 104 items, thus obtaining a shorter measuring instrument with a total of 196 items for ease of application.

Conclusions

The content validity of the test is adequate and fits the agreed definition of depression.

Effect of an Interdisciplinary Weight Loss and Lifestyle Intervention on Obstructive Sleep Apnea Severity: The INTERAPNEA Randomized Clinical Trial

IMPORTANCE

Obesity is the leading cause of obstructive sleep apnea (OSA); however, the effects of weight loss and lifestyle interventions on OSA and comorbidities remain uncertain.

OBJECTIVE

To evaluate the effect of an interdisciplinary weight loss and lifestyle intervention on OSA and comorbidities among adults with moderate to severe OSA and overweight or obesity.

DESIGN, SETTING, AND PARTICIPANTS

The Interdisciplinary Weight Loss and Lifestyle Intervention for OSA (INTERAPNEA) study was a parallel-group open-label randomized clinical trial conducted at a hospital-based referral center in Granada, Spain, from April 1, 2019, to October 23, 2020. The study enrolled 89 Spanish men aged 18 to 65 years with moderate to severe OSA and a body mass index (calculated as weight in kilograms divided by height in meters squared) of 25 or greater who were receiving continuous positive airway pressure (CPAP) therapy. The sole inclusion of men was based on the higher incidence and prevalence of OSA in this population, the differences in OSA phenotypes between men and women, and the known effectiveness of weight loss interventions among men vs women.

INTERVENTIONS

Participants were randomized to receive usual care (CPAP therapy) or an 8-week weight loss and lifestyle intervention involving nutritional behavior change, aerobic exercise, sleep hygiene, and alcohol and tobacco cessation combined with usual care.

MAIN OUTCOMES AND MEASURES

The primary end point was the change in the apnea-hypopnea index (AHI) from baseline to the intervention end point (8 weeks) and 6 months after intervention. Secondary end points comprised changes in other OSA sleep-related outcomes, body weight and composition, cardiometabolic risk, and health-related quality of life.

RESULTS

Among 89 men (mean [SD] age, 54.1 [8.0] years; all of Spanish ethnicity; mean [SD] AHI, 41.3 [22.2] events/h), 49 were randomized to the control group and 40 were randomized to the intervention group. The intervention group had a greater decrease in AHI (51% reduction; change, -21.2 events/h; 95% CI, -25.4 to -16.9 events/h) than the control group (change, 2.5 events/h; 95% CI, -2.0 to 6.9 events/h) at the intervention end point, with a mean between-group difference of -23.6 events/h (95% CI, -28.7 to -18.5 events/h). At 6 months after intervention, the reduction in AHI was 57% in the intervention group, with a mean between-group difference of -23.8 events/h (95% CI, -28.3 to -19.3 events/h). In the intervention group, 18 of 40 participants (45.0%) no longer required CPAP therapy at the intervention end point, and 6 of 40 participants (15.0%) attained complete OSA remission. At 6 months after intervention, 21 of 34 participants (61.8%) no longer required CPAP therapy, and complete remission of OSA was attained by 10 of 34 participants (29.4%). In the intervention vs control group, greater improvements in body weight (change, -7.1 kg [95% CI, -8.6 to -5.5 kg] vs -0.3 kg [95% CI, -1.9 to 1.4 kg]) and composition (eg, change in fat mass, -2.9 kg [95% CI, -4.5 to -1.3 kg] vs 1.4 kg [95% CI, -0.3 to 3.1 kg]), cardiometabolic risk (eg, change in blood pressure, -6.5 mm Hg [95% CI, -10.3 to -2.6 mm Hg] vs 2.2 mm Hg [95% CI, -2.1 to 6.6 mm Hg]), and health-related quality of life (eg, change in Sleep Apnea Quality of Life Index, 0.8 points [95% CI, 0.5-1.1 points] vs 0.1 points [95% CI, -0.3 to 0.4 points]) were also found at the intervention end point.

CONCLUSIONS AND RELEVANCE

In this study, an interdisciplinary weight loss and lifestyle intervention involving Spanish men with moderate to severe OSA and had overweight or obesity and were receiving CPAP therapy resulted in clinically meaningful and sustainable improvements in OSA severity and comorbidities as well as health-related quality of life. This approach may therefore be considered as a central strategy to address the substantial impact of this increasingly common sleep-disordered breathing condition.

Characteristics of sleep spindles in school-aged children with attention-deficit/hyperactivity disorder

OBJECTIVE

Attention deficit/hyperactivity disorder (ADHD) is a complex disorder, characterized by different presentations with distinct cognitive and neurobiological characterizations. Here we aimed to investigate whether sleep spindle activity, which has been associated with brain maturation, may be a potential biomarker able to differentiate ADHD presentations in school-aged children (7-11 years).

METHOD

Spindle characteristics were extracted from overnight polysomnography in 74 children (27 ADHD-Inattentive [IQ = 96.04], 25 ADHD-hyperactive/impulsive [IQ = 98.9], and 22 ADHD-combined [IQ = 96.1]). We obtained data of the frontal (Fz) and parietal (Pz) derivations using a validated spindle detection algorithm.

RESULTS

Children with ADHD showed a higher number and density of slow compared to fast spindles which were more frequent in frontal area. No differences were observed among ADHD presentations for any spindle characteristics. Spindle frequency and density increased with age, indicating an age-dependent maturation of different sleep spindles. However, no associations between IQ and spindle characteristics were observed.

CONCLUSIONS

In children with ADHD the spindle characteristics evolve with age but sleep spindle activity does not seem to be a valid biomarker of ADHD phenotypes or general cognitive ability.

Sleep, academic achievement, and cognitive performance in children with attention-deficit hyperactivity disorder: A polysomnographic study

The objective of this study was to examine the influence of parent-reported and polysomnography (PSG)-measured sleep patterns on the academic and cognitive performance of children with attention-deficit hyperactivity disorder (ADHD). We assessed 91 children (18 girls) diagnosed with ADHD aged 7-11 years (29 ADHD-Inattentive, 32 ADHD-Hyperactive/Impulsive, and 31 ADHD-Combined). The Paediatric Sleep Questionnaire (PSQ) and Paediatric Daytime Sleepiness Scale (PDSS) were used to assess subjective sleep quality, as perceived by parents, and objective sleep variables were assessed by PSG. Cognitive performance was evaluated using the Wechsler Intelligence Scale for Children (WISC), and the final average grade of the last school year was used as a measure of academic performance. Academic performance was predicted by the following sleep variables: Sleep time, time in bed, night awakenings, and daytime sleepiness. The best predictors of cognitive performance in children with ADHD were rapid eye movement latency, light sleep, periodic limb movements index (PLMs), awakenings, and daytime sleepiness. In conclusion, sleep parameters are closely associated with the academic and cognitive functioning of children with ADHD.

A Meta-Analysis of the Generalization of the Reliability of State/Trait Depression Inventory Scores

BACKGROUND

Depression is a disorder that is highly prevalent nowadays. Within the dimensional explanatory model of depression, the State/Trait Depression Inventory was developed. Its objective is to identify the degree of affectation (state) and the frequency of occurrence (trait) of the affective component of depression. The instrument has proven reliable and comprises two factors in its structure: state and trait, with two euthymia and dysthymia subscales in each one. The objective of this meta-analysis is to find an average alpha for the questionnaire.

METHOD

A bibliographical search was conducted on Web of Science and Scopus. Forty-five articles were selected.

RESULTS

The alpha ranges from .84 to .89 for all factorizations, and in most studies a bifactorial structure of state and trait depression was found.

CONCLUSIONS

The State/Trait Depression Inventory is a reliable and suitable instrument for measuring depression.

Teacher Satisfaction in Spain with the European Higher Education Area: Arts and Humanities

In Spain reforms to university educational policy have been made in order to adapt to the European Higher Education Area (EHEA). Therefore, the objective of this study was to find out the level of satisfaction of Arts and Humanities university teaching staff towards the implementation of the EHEA. It is a population-based, descriptive study using a cross-sectional survey with a probability sample. The sample consisted of 1605 Spanish teachers of Arts and Humanities from public universities (with an average age of 48 years, of which 52 % were women and 48 % men). They were applied an ad hoc survey (α = 0.82) consisting of questions (grouped into eight sections) about the degree of satisfaction towards different aspects of the EHEA. In the results can be observed that teachers are not completely satisfied with the way in which educational institutions have adapted university education to the EHEA and they have identified certain needs that limit the quality of Arts and Humanities teaching. In conclusion, the most of teachers thought that the implementation of the EHEA could be improved, although a small percentage believed that it had not been implemented correctly.

Anxiety and Depression in Patients with Obstructive Sleep Apnoea before and after Continuous Positive Airway Pressure: The ADIPOSA Study

The prevalence and treatment response of depression and anxiety symptoms in obstructive sleep apnoea (OSA), although widely addressed in research and clinical settings, still remain unclear due to overlapping symptoms. The ADIPOSA study sought to elucidate the presence of non-overlapping symptoms of depression and anxiety in patients with moderate to severe OSA before and after continuous positive airway pressure (CPAP) treatment. Forty-eight adults aged 18-80 (68.75% men) with moderate to severe OSA were enrolled in this twelve-week longitudinal single-arm trial and completed a full-night ambulatory sleep diagnostic test and an assessment of cognitive-affective depression and anxiety symptoms using the Beck-Depression Inventory-Fast Screen (BDI-FS), the State-Trait Depression Inventory (IDER) and the State-Trait Anxiety Inventory (STAI). We found no cognitive-affective depression or anxiety symptoms of clinical relevance at baseline. The amelioration of depression and anxiety symptoms after CPAP use was only statistically significant when considering anxiety-trait (p < 0.01; d = 0.296) and euthymia (p < 0.05; d = 0.402), the distinctive component of depression. Although dysthymia or high negative affect remained unchanged, CPAP may be effective at reducing the lack of positive affect, a well-established health-protective factor. However, not until depression and anxiety disorders related to OSA are accurately measured in clinical and research settings will it be possible to obtain robust conclusions on the occurrence and amelioration of these symptoms after treatment.

[Research Ranking of Spanish Public Universities (2019)]

Research Ranking of Spanish Public Universities (2019).

BACKGROUND

The changes produced in the Spanish university system due to the Bologna process require periodically updated evaluation reports of research activity. The objective of this study is to update the last available ranking of Spanish public universities, based on data from 2013-2018.

METHOD

The production and productivity of each university were assessed based on seven specific indicators and a global score: articles in journals indexed in the JCR (Journal Citation Reports), research periods, R+D projects, doctoral theses, FPU (training of university professors) grants, FPI (training of personal researchers) grants, and patents.

RESULTS

Globally, the universities Complutense of Madrid, Barcelona, and Granada hold the first positions in terms of production, while the first positions in terms of productivity are held by the universities Pompeu Fabra, Autonomous of Madrid, and Autonomous of Barcelona.

CONCLUSIONS

The universities that hold the top positions in this ranking remain relatively steady over time and are also the Spanish universities that stand out in international classifications.

Sleep among presentations of Attention-Deficit/Hyperactivity Disorder: Analysis of objective and subjective measures

To examine subjective and objective sleep patterns in children with different Attention-Deficit/Hyperactivity Disorder (ADHD) presentations.

METHOD

We assessed 92 children diagnosed with ADHD (29 ADHD-Inattentive [ADHD-I], 31 ADHD-Hyperactive/Impulsive [ADHD-H/I], and 32 ADHD-Combined [ADHD-C)]) aged 7-11 years. The Pediatric Sleep Questionnaire (PSQ), Pediatric Daytime Sleepiness Scale (PDSS), and a sleep diary were used as subjective sleep measures, and polysomnography was used to objectively assess sleep quantity, quality, and fragmentation.

RESULTS

Subjective data showed impaired sleep in 12.7% of the sample. No significant differences were found between ADHD presentations in any objective and subjective sleep variable. Nevertheless, data on sleep fragmentation suggested a worse sleep continuity for the ADHD-H/I group, and correlation analyses confirmed that sleep is affected by age.

CONCLUSIONS

Children with ADHD may suffer from sleep breathing problems and daytime sleepiness, as reported by their parents, even when their total sleep time and sleep efficiency are not affected. It seems that sleep in this population does not largely vary as a function of the ADHD presentation. Sleep in children with ADHD evolves with age.

Reliability and validity of the Basic Depression Questionnaire

Depressive disorders have a high prevalence around the world. They present a great comorbidity with other disorders like anxiety, thereby making a differential diagnosis very difficult. The Basic Depression Questionnaire was designed to palliate this issue by isolating specific depression symptoms. Our aim is to study the reliability, factorial structure, and differential item functioning of this questionnaire.

METHOD

The sample consisted of 1,397 adults without psychological problems (M _age  = 29.76, SD = 11.25, 64.78% women) who completed the CBD.

RESULTS

We observed that none of the items presented differential functioning. A monofactorial structure was established. In this model a good fit was obtained by confirmatory factor analysis and a strict invariance by sex. The ordinal alpha was used to check the reliability and it fetched an index of .95.

CONCLUSIONS

The Basic Depression Questionnaire has adequate psychometric properties. The absence of differential item functioning and the invariance by sex are guarantees of an adequate use to diagnose depression for men and women. So, its clinical use can help to differentiate between the specific diagnoses for depressive disorders and anxiety disorders.

Shorter REM latency in children with attention-deficit/hyperactivity disorder

The discrepancies in prior research about the actual sleep problems underlying attention-deficit/hyperactivity disorder (ADHD) demand more studies of children with this disorder. This study aimed to compare the subjective and objective sleep characteristics of 20 children with ADHD (DSM-IV criteria) and 20 typically developing children (aged 7-11 years). We assessed the children using sleep questionnaires and polysomnography recordings and analysed differences between the two groups using two-tailed Mann-Whitney U exact tests and Rosenthal's r as effect size measure. We also assessed associations between sleep measures and psychopathology using Spearman's correlation coefficients. No significant difference was found between the groups in almost any objective sleep variable, except for shorter REM latency in the ADHD group. Children with ADHD also showed significantly higher levels of daytime sleepiness and greater general sleep problems than control children, as reported by their parents, after discarding the primary sleep problems commonly associated with ADHD. Significant correlations were found between psychopathology and sleep measures. Our findings might support the link between narcolepsy-like sleep phenotype and ADHD. However, longitudinal research combining objective and subjective assessments should further explore the involvement of other variables, such as ADHD subtypes, medication, and comorbid symptoms in this relationship.

Weight loss and lifestyle interventions for obstructive sleep apnoea in adults: Systematic review and meta-analysis

Lifestyle interventions addressing diet, exercise-training, sleep hygiene, and/or tobacco/alcohol cessation are recommended in the management of obstructive sleep apnoea (OSA). Yet their effectiveness on this condition still requires further research. This systematic review and meta-analysis was aimed at establishing (a) the effectiveness of lifestyle interventions on apnoea-hypopnoea index (AHI), oxygen desaturation index (ODI), excessive daytime sleepiness (EDS), and secondary OSA measures among adults, and (b) which intervention characteristics may drive the greatest improvements. A systematic search of studies was conducted using CINAHL, ProQuest, Psicodoc, Scopus, and Web of Science, from inception to April 2018. Standardized mean differences were calculated using the inverse variance method and random-effects models. The meta-analyses of 13 randomized controlled trials and 22 uncontrolled before-and-after studies (1420 participants) revealed significant reductions on AHI (d = -0.61 and -0.46, respectively), ODI (d = -0.61 and -0.46) and EDS (d = -0.41 and -0.49). Secondary OSA outcomes were also improved after interventions. However, effectiveness of interventions differed depending on their components, OSA severity, and gender. Thus, until future research further supports the differential effectiveness among lifestyle interventions on OSA, those addressing weight loss through diet and exercise-training may be the most effective treatments for male patients with moderate-severe OSA.

Sexism and sexual risk behavior in adolescents: Gender differences

Background/Objective: This study examines whether there are differences in the maintenance of ambivalent sexist beliefs on the basis of gender and sexual experience in adolescents. The study also investigates whether the sexist beliefs themselves are linked to sexual risk behaviors. Method: A representative sample of 2,703 Spanish adolescents was carried out in public and private secondary schools, with an age range of 14 to 20 years old (M = 15.89; SD = 1.29). Results: Males maintain more hostile, benevolent and ambivalent sexist beliefs compared to females. Sexual experience (both coital and non-coital) is linked to a greater degree of hostile and benevolent sexist beliefs, but only within the male group. In males, greater benevolent sexism is linked to vaginal sex initiation at an earlier age, while greater hostile sexism is linked to a lower proportion of condom use. In females, greater hostile sexism is linked to a greater number of sex partners. Conclusions: It is necessary to include specific actions on sexist beliefs in programs for the prevention of sexually transmitted infections and HIV.

Short form of the Spanish adaptation of the State-Trait Anxiety Inventory

Background/Objective: The State-Trait Anxiety Inventory (STAI) is one of the assessment instruments that are most widely used by psychologists around the world and is the seventh most broadly used by clinical psychologists in Spain. Although several short forms of the STAI have been developed since its creation, none are available for the Spanish general population. The aim of the present study was to develop and validate a short form of the STAI. Method: To achieve this, we administered the full STAI to 1,157 healthy adults, and 30 patients with generalized anxiety disorder. We conducted a discriminant analysis using such groups. Results: We obtained a selection of four items for state anxiety and four items for trait anxiety and compared it to other short forms through a confirmatory factor analysis. The short form obtained with the discriminant analysis showed the best fit for Spanish samples. Conclusions: these eight items can be used to facilitate the state and trait anxiety assessment.

Risk factors related to intimate partner violence police recidivism in Spain

Background/Objective: Some professionals, such as police officers, are required to prevent violent behavior, such as intimate partner violence (IPV). For this task they use actuarial tools designed to estimate the risk of occurrence of further violence after a previous complaint (police recidivism), taking into account risk and protective indicators which they can observe, in spite of they are not behavioral assessment experts. Method: To try to refine the police risk assessments carried out in Spain since 2007 and to improve the two tools available on the Spanish VioGén System, Police Risk Assessment and Risk Evolution (VPR_3.1 and VPER_3.0), this paper, using an epidemiological design, in a sample of 6,613 new cases of IPV of Spain, studies empirical relationships among 65 indicators (56 risk and 9 protection) and IPV police recidivism up to six months. Results: It resulted in a recidivism rate of 7.4%, finding statistically significant associations of 46 indicators. Conclusions: Empirical evidence about static indicators and new relevant dynamic indicators in the victims’ police protection management is presented. Practical implications for future police risk assessments are discussed.

Sleep Characteristics in Children with Attention Deficit Hyperactivity Disorder: Systematic Review and Meta-Analyses

STUDY OBJECTIVES

Sleep disturbances have been associated with attention deficit hyperactivity disorder (ADHD), but such relationship is still unclear. The results from the studies conducted do not provide enough evidence to support a sleep physiology inherent to ADHD. This study tries to determine if that sleep physiology really exists by comparing children with ADHD and control children in some sleep parameters.

METHODS

A search was conducted in several databases (Web of Science, Scopus, Pubmed and PsycINFO), and a manual search, to retrieve all the articles available from 1987 until March 2014. Of 8,678 non-duplicate studies retrieved, 11 studies met the inclusion and methodological quality criteria. Two meta-analyses were performed with eight of those studies, depending on data provided by them: polysomnographic or actigraphic. A fixed-effects model, and the standardized mean difference (SMD) as the index of effect size, were used in both meta-analyses.

RESULTS

Significant differences were found only in the meta-analysis with polysomnography as outcome. Children with ADHD were found to spend more time in stage 1 sleep than controls (pooled SMD = 0.32, 95% CI = 0.08-0.55, p value = 0.009).

CONCLUSIONS

Although few differences in sleep between children with ADHD and controls have been found in this review, further studies are required on this matter. Those studies should consider some variables discussed in this review, in order to obtain useful and reliable conclusions for research and clinical practice. Particularly, the influence of assessment criteria and ADHD subtypes in the sleep characteristics of children with ADHD should be addressed.

Conceptualización y Evaluación de la Impulsividad en Adolescentes: una Revisión Sistemática

La impulsividad es un constructo ampliamente estudiado y se ha caracterizado por la falta de consenso entre los autores sobre: su definición, características y formas de evaluación; generando que actualmente sea un constructo complejo. Se realizó la revisión sistemática sobre impulsividad en adolescentes, con el objetivo de identificar las diferentes definiciones, analizar las medidas que son usadas para evaluar impulsividad y puntualizar los diferentes rasgos psicológicos con los cuales se relaciona en la investigación. La recopilación de artículos se hizo por medio de las bases de datos, Web of Knowledge, Scopus, PsycInfo, Scielo, Redalyc, Google Escolar, Teseo y Cochrane, donde se seleccionaron 3.457 artículos de los cuales se revisaron 108 artículos. Los resultados muestran las definiciones de impulsividad, la población, medidas de evaluación y la relación con otras variables. Se concluye que, (a) la impulsividad es un constructo con múltiples definiciones, (b) se identificó el MFFT como medida más usada para evaluar el constructo y (c) se encontró que se ha investigado su relación en temas como problemas de conducta, medidas cognitivas, agresión y aspectos familiares.

[2013 research ranking of Spanish public universities]

BACKGROUND

The evaluation of research production and productivity is becoming increasingly necessary for universities. Having reliable and clear data is extremely useful in order to uncover strengths and weaknesses. The objective of this article is to update the research ranking of Spanish public universities with the 2013 data.

METHOD

Assessment was carried out based on articles in journals indexed in the JCR, research periods, R+D projects, doctoral theses, FPU grants, doctoral studies awarded with a citation of excellence, and patents, providing a rating, both for each individual indicator and globally, in production and productivity. The same methodology as previous editions was followed.

RESULTS

In the global ranking, the universities with a higher production are Barcelona, Complutense of Madrid, and Granada. In productivity, the first positions are held by the universities Pompeu Fabra, Pablo de Olavide, and the Autonomous University of Barcelona.

CONCLUSIONS

Differences can be found between the universities in production and productivity, while there are also certain similarities with regard to the position of Spanish universities in international rankings.

Power dynamics in adolescent couple relationships and risk of sexually transmitted infections and HIV

The aim of this study was to determine whether there are differences in power distribution between males and females in couple relationships, and whether these differences are associated with risky sexual behaviour in a representative sample of Spanish adolescents. The study also examined the influence of partner's age on the power dynamics that occur in a relationship. The sample comprised 1,223 adolescents attending state and private schools in the 17 autonomous regions in Spain. All adolescents included in the sample were involved in a heterosexual relationship (for at least one month) at the time of evaluation. Relationship control and decision-making dominance were evaluated using the Spanish version of the Sexual Relationship Power Scale. Two further questionnaires were administered to collect sociodemographic data, and data on sexual behaviour. Females showed greater relationship control and greater control over decision-making than males. In the female group, participants with partners five or more years older than them were found to have less control over decision-making, while greater control over decision-making was linked to less exposure to risk. In the male group, participants with partners older than them were found to have greater control over decisionmaking, while relationship control was found to be negatively related to exposure to sexual risk. These results highlight the importance of taking power distribution and gender inequalities in couple relationships into consideration for STI and HIV prevention.

Sleep disturbances of adult women suffering from fibromyalgia: a systematic review of observational studies

Although sleep complaints are often reported in patients with fibromyalgia syndrome (FMS), there is no conclusive evidence that these complaints represent symptomatic disorders of sleep physiology. Thus, the question of the role of sleep disturbances as an etiological or maintenance factor in FMS remains open. This study identifies the subjective and objective characteristics of sleep disturbances in adult women diagnosed with FMS. We carried out a systematic review of publications since 1990, the publication year of the American College of Rheumatology criteria of FMS. We selected empirical studies comparing sleep characteristics of adult women with FMS and healthy women or women with rheumatic diseases. We identified 42 articles. Patients with FMS were more likely to exhibit sleep complaints and also a less efficient, lighter and fragmented sleep. The evidence of a FMS signature on objective measures of sleep is inconsistent, however, as the majority of studies lacks statistical power. Current evidence cannot confirm the role played by sleep physiology in the pathogenesis or maintenance of FMS symptoms; nonetheless, it is clear that sleep disturbances are present in this syndrome.

Workplace accidents, absenteeism and productivity in patients with sleep apnea

INTRODUCTION

Obstructive sleep apnea-hypopnea syndrome (OSAHS) has health-related outcomes, but the impact of OSAHS on occupational health has been scarcely studied. The aim of this study was to evaluate the effect of OSAHS on workplace accidents, absenteeism and productivity.

METHOD

One hundred eighty-two OSAHS patients and 71 healthy subjects completed the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index and the Spanish IMPALA (Impact of Disease on Work Productivity) index and answered various questions on workplace accidents and sick leave. Participants were classified to an OSAHS group or a non-OSAHS group according to polysomnography results.

RESULTS

Patients with OSAHS had more sick leave lasting longer than 30days (16.6% vs. 7%, P=.049) and lower productivity (63.80% vs. 83.20%, P=.000) than subjects without OSAHS, although the rate of workplace accidents was similar in both groups (27.4% vs 25.4%; P>.050). None of the OSAHS-related variables was associated with workplace accidents. A diagnosis of OSAHS was related with absenteeism. Psychological distress and OSAHS were related with productivity.

CONCLUSIONS

OSAHS causes limitations in the working lives of patients and leads to a higher incidence of sick leave and lower productivity. A diagnosis of OSAHS was the variable with most influence on the working lives of patients.

Job stress, burnout, and job satisfaction in sleep apnea patients

OBJECTIVE

To assess job stress, burnout, and job satisfaction in patients with obstructive sleep apnea syndrome (OSAS).

METHODS

A total of 182 patients with OSAS and 71 healthy individuals completed the Job Content Questionnaire, the Maslach Burnout Inventory - General Survey, the Index of Job Satisfaction, the Epworth Sleepiness Scale, and the Pittsburgh Sleep Quality Index. All participants were assessed with full-night polysomnography.

RESULTS

Survey scores of patients diagnosed with OSAS only differed from those of the control group in the emotional exhaustion dimension (P = 0.015). According to a multivariate analysis, the apnea-hypopnea index (AHI) was only correlated with perceived support at work (β coefficient = 0.142; P = 0.048). Associations were found between subjective sleep quality, perceived support from coworkers, and supervisors (β = 0.157; P = 0.025), psychological demands (β = 0.226; P = 0.001), emotional exhaustion (β = 0,405; P = 0.000), and cynicism (β = 0.224; P = 0.002). The study also revealed associations between excessive daytime sleepiness and the burnout dimensions emotional exhaustion (β = 0.232; P = 0.000) and cynicism (β = 0.139; P = 0.048).

CONCLUSION

Objective parameters of OSAS such as the AHI seem to have limited influence on the psychosocial aspects of the occupational life of patients with OSAS. There is evidence of significant associations between the subjective symptoms of the disease, such as daytime sleepiness, subjective sleep quality, job stress, and burnout.

[Meta-analysis of group comparison and meta-analysis of reliability generalization of the State-Trait Anxiety Inventory Questionnaire (STAI)]

BACKGROUND

Since its creation the STAI has been cited in more than 14,000 documents, with more than 60 adaptations in different countries. In some adaptations this instrument has no clinical scores. The aim of this work is to determine if the State-Trait Anxiety Inventory (STAI) has higher scores in patients diagnosed with anxiety than in general population. In addition, we want to examine if the internal consistency is adequate in anxious patient samples.

METHODS

We performed a literature search in Tripdatabase, Cochrane, Web of Knowledge, Scopus, PyscINFO and Scholar Google, for documents published between 2008 y 2012. We selected 131 scientific articles to compare between patients diagnosed with anxiety and general population, and 25 for the generalization of reliability. For the analysis we used Cohen's d for means comparisons (random-effects method) and Cronbach's alpha for the reliability generalization (fixed-effects method).

RESULTS

In the groups comparision the differences in state anxiety (d=1.39; CI95%: 1.22-1.56) and in the trait anxiety (d=1.74; CI95%:1.56-1.91) were significants. The reliability for patients of some anxiety disorder was between 0.87 and 0.93.

CONCLUSIONS

So it seems that the STAI is sensitive to the level of anxiety of the individual and reliable for patients with diagnosis of panic attack, specific phobia, social phobia, generalized social phobia, generalized anxiety disorder, post-traumatic stress disorder, obsessive compulsive disorder or acute Stress disorder.

Time perception and psychopathology: Influence of time perspective on quality of life of severe mental illness

INTRODUCTION

The study of time perception and mental illness has given priority to time estimation over time perspective. Considering Zimbardo’s theory on five dimensions of time perspective, and balanced time perspective profile, this study has aimed to compare people with severe mental illness (SMI) and healthy people, with measurements of time perspective and time estimation and to assess whether the time perspective profile influences the quality of life in people with SMI.

MATERIAL AND METHODS

Using a quasi-experimental design, a clinical group (n=167) corresponding to four samples of severe mental disorders (major depression, bipolar disorder, schizophrenia and personality disorders) and healthy people (n=167) were compared in their performance regarding time perspective and time estimation. After, the clinical sample was grouped according to their deviation from the balanced time perspective profile (DBTP) and negative profile (DNTP). These groups were evaluated with health measures and time estimation tasks.

RESULTS AND CONCLUSION

Through the ANOVA, it can be seen that the time perspective profile affects health measurements. There are significant differences between the clinical sample and controls regarding time perspective and time estimation. Within the group of patients, it was observed that those who were closer to the BTP profile had better physical health, and less hopelessness (p<.05). This measurement may favor interventions related to a balanced profile. Results are discussed in relation to contribution of time perspective in the assessment, treatment and quality of life of people with SMI.

[2012 ranking in research in Spanish public universities]

2012 ranking in research in Spanish public universities.

BACKGROUND

In order to guarantee the usefulness of promotion policies for the investigation of educational institutions, in recent years studies analyzing different indicators have been developed, with the intention of valuing possible changes in the future. The objective of this work is to update the research production and productivity ranking of Spanish public universities, using data from 2012.

METHOD

The same methodology as previous years has been followed. Seven indicators have been evaluated: articles from journals indexed in the JCR, research lines, R+D projects, doctoral theses, Spanish research and training grants, doctorate courses awarded a mention of excellence and patents.

RESULTS

Amongst the results obtained in the global ranking there are differences between the universities with a higher production (University of Barcelona, Complutense University of Madrid and the University of Granada) and those with a higher productivity (Pompeu Fabra, Pablo de Olavide and Miguel Hern&aacute;ndez de Elche).

CONCLUSIONS

When comparing the results to those of 2011, it can be observed that the three most productive universities remain in the same positions.

Psychosocial Correlates of Condom Use and their Relationship with Worry about STI and HIV in Native and Immigrant Adolescents in Spain

The goal of this study was to analyze how worry about sexually-transmitted infections (STI) and HIV influences attitudes and self-efficacy towards condom use, HIV-related knowledge, HIV-perceived susceptibility and HIV-misconceptions in a multicultural sample in Spain. The sample was composed of 3,051 adolescents aged between 14 and 19 years old who lived in Spain. Of these, 67.7% were native Spaniards and the remaining 32.3% were Latin American immigrants. Results showed that worry about STI and HIV has a direct influence on condom use self-efficacy and HIV-knowledge and HIV-perceived susceptibility. Native Spanish adolescents showed higher positive attitudes towards condom use, greater HIV-knowledge and HIV-perceived susceptibility, and lower negative attitudes towards condoms use and HIV-misconceptions than Latin American adolescents. In the discussion, the importance of worry about STI and HIV is highlighted as a mediator variable that can predict risky sexual behavior and is related to cultural origin.

Análisis de los Programas de Doctorado con Mención de Calidad

La Mención de Calidad, concedida por la Agencia Nacional de Evaluación de la Calidad y Acreditación, supuso el reconocimiento a la solvencia científico-técnica y formadora de los programas de doctorado de las universidades españolas. Desde el curso 2003-2004, el número de programas con esta distinción aumentó  en un 60%. Se analizaron 671 programas de doctorado a los que se les concedió  la Mención de Calidad en la última convocatoria de 2007. La información se  recogió a través de las páginas webs de todos los programas, la legislación de la  universidad a la que pertenecen y a partir de una encuesta online enviada a los  coordinadores. En los resultados se observan aspectos relacionados con los rasgos generales de los programas de doctorado, rasgos comunes entre periodo formativo e investigador, rasgos propios de periodo de máster, y por último, rasgos propios del periodo investigador. Finalmente, se discuten estos rasgos estableciendo diferencias entre ambos periodos.

[2011 ranking in production and research productivity in Spanish public universities]

The assessment and improvement of the quality of scientific research in the universities is one of the main goals of the European Space for Higher Education. Within this goal, increased interest in national and international rankings has been shown. The objective of this research is to update the scientific research productivity ranking of Spanish public universities and it is based on data corresponding to 2011. The methodology of this research is similar to those of past research, including not only the assessment of productivity, but the total production of each university. Seven indicators were assessed: articles in JCR-indexed journals, scientific research periods, I+D projects, doctoral dissertations, FPU scholarships, doctoral programs towards Excellence Mention, and patents. Results show a notable difference between universities with a higher production (University of Barcelona, Complutense University of Madrid, and University of Granada) and those that are the most productive (Pompeu Fabra, Pablo de Olavide, and Rovira i Virgili). The results obtained are analyzed in the discussion with special focus on the evolution of research in Spanish public universities in the past four years. Some challenges for the future are also discussed.

Is Psychology a Health Profession? An Opinion of a Sample of Psychologists Worldwide

The purpose of the current study is to evaluate the opinions of the scientific community of psychologists on the question if psychology is a health profession. Nowadays, the subject is even more important as there are laws, as for example the Ley de Ordenación de Profesiones Sanitarias (LOPS) [Law for the Organization of the Health Professions] in Spain that should be based on the concept that psychology is or is not a health profession. Moreover, the creation of the common curricula for the whole Europe needs the general agreement and no individual opinion can be valid for these purposes. The present study shows the opinion of 803 scientists who have published at least one article in a clinical or multidisciplinary psychology journal included in the Web of Science, from 42 different countries, 23 major fields of psychology and 32 orientations. The results show that, in general, the participants answered that psychology is a health profession, which is even more evident in case of clinical psychology.

[Current epidemiological situation of HIV/AIDS in Latin America: analysis of differences among countries]

BACKGROUND

There is a great regional heterogeneity in the prevalence of HIV/ AIDS.

AIM

To analyze the current situation of HIV/AIDS in Latin America by means of a comparative analysis among countries.

MATERIAL AND METHODS

In a descriptive study (document analysis), epidemiological data about HIV/AIDS in Latin America as well as population data were used. Prevalence indexes and the distribution of HIV/AIDS cases were compared according to gender, age and transmission mode.

RESULTS

Dominican Republic, Panama, El Salvador and Honduras are the countries with the highest prevalence indexes. Colombia is in the first position in percentage of young men with HIV/AIDS and it is in the second position in percentage of children. Costa Rica is the second country for percentage of young men and male adults infected with HIV/AIDS. Paraguay is in the second place for children with HIV/AIDS and it is the third country in young men living with HIV/AIDS. Dominican Republic is in the first position in the percentage of young and adult females living with HIV/AIDS. The main transmission mode in all Latin American countries is sexual intercourse (heterosexual and homo/bisexual).

CONCLUSIONS

Latin America is a heterogeneous region in HIV/AIDS which should be considered in the development and establishment of prevention strategies.

How to measure the internationality of scientific publications

Although the term "internationality" has never been defined by consensus, it is commonly used as a synonym of quality. Even though its meaning has never been established, internationality is frequently used to evaluate scientists, publications, or universities in many different countries. The present investigation is based on the opinion about the meaning of the concept "internationality" of the members of scientific community, represented by a broad sample of 16,056 scientists from 109 countries working in all the fields of knowledge defined by UNESCO. The sample was randomly selected from the Web of Science database from the scientists who have published at least one article in one of the journals indexed by the database. A questionnaire based on eleven criteria was designed for the purpose of the study. As a result, the first measure of internationality has been obtained. The most important criteria of internationality are: the publication language, online access, and international publication standards. There are significant differences among geographic zones and fields of knowledge.

Chilean validation of the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) after the earthquake on February 27, 2010

Posttraumatic stress disorder (PTSD) is an anxiety disorder in which an individual re-experiences a traumatic event, avoids situations related to it, and shows excessive arousal. The disorder appears after experiencing a life-threatening event, such as a war or a natural disaster. Thus, the validation of tests which assess the disorder after the earthquake on February 27, 2010, in Chile is crucial for its evaluation and subsequent intervention. The present study includes psychometric data for the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) on a sample of 509 survivors of the disaster. Values indicate good psychometric properties of the questionnaire.

[Ranking 2010 in production and research productivity in Spanish public universities]

The creation of the European Higher Education Area has brought the relevance of the scientific quality assessment in higher education. The result of this interest is a growing interest in the development of rankings of universities, both nationally and internationally. To continue the line started two years ago, the goal of this research is to update the ranking of research productivity in Spanish public universities with the data of 2010. We follow the same methodology to data from 2008 and 2009; although this year it includes measures of total production. The same indicators to evaluate research in 2009: journals articles indexed in the JCR, research periods, research + development projects, doctoral dissertations, grants for training university teachers, Doctoral Programs with Quality Mention and patents. From the results obtained show that universities with higher production were Complutense de Madrid, Barcelona and Granada. The most productive were the Pompeu Fabra University, the Pablo de Olavide, and the Autonoma de Barcelona.
