Opioid withdrawal is characterized by a set of physical and psychological symptoms that depend on both opioid and patient specific characteristics. The present study aims to identify different latent classes of chronic pain patients according to the type of opioid withdrawal symptoms experienced, and to analyze the relationships between the classes and demographic, opioid therapy, psychological and substance use variables. This cross-sectional descriptive study included 391 chronic pain patients on long-term opioid therapy. A Latent Class Analysis (LCA) identified 3 classes (BIC = 7051.89, entropy = .87, LRTs P.01). The mild withdrawal class showed low probabilities of presenting physical and psychological symptoms, the moderate withdrawal class was characterized by experiencing psychological symptoms, and the severe withdrawal class stood out for high probabilities of presenting both types of symptoms. The classes differed from each other, with higher rates of moderate-severe POUD, opioid misuse, anxiety, depression, and greater pain intensity and interference in more severe withdrawal classes (P.05). The multinomial logistic regression showed that moderate-severe POUD and anxiety were the strongest variables related to moderate (OR

A new species of the genus Liropus Mayer, 1920 (Amphipoda, Caprellidae) is described from the Mexican Tropical Pacific coast. Liropus alarconi n. sp. is described on the basis of four specimens collected in association with the tropical marine sponge Trikentrion helium Dickinson, 1945, near to coralline patches, between 23–30 m depth. Liropus alarconi n. sp. can be distinguished from its congeners for the following characters: pereonites 2–5 each with one dorsodistal projection and pereonite 3 with a mediolateral projection.

Empirically Supported Psychological Treatments for Children and Adolescents: State of the Art.The empirical evidence accumulated on the efficacy, effectiveness, and efficiency of psychotherapeutic treatments in children and adolescents calls for an update. The main goal of this paper objective was to carry out a selective review of empirically supported psychological treatments for a variety of common psychological disorders and problems in childhood and adolescence.A review was carried out of the psychological treatments for different psychological disorders and problems in social-emotional or behavioral adjustment in the child-adolescent population according to the Spanish National Health System (Clinical Practice Guidelines) levels of evidence and degrees of recommendation.The findings suggest that psychological treatments have empirical support for addressing a wide range of psychological problems in these developmental stages. The degree of empirical support ranges from low to high depending on the phenomenon analyzed. The review suggests unequal progress in the different fields of intervention.From this update, psychologists will be able to make informed decisions when implementing those empirically supported treatments to address the problems that occur in childhood and adolescence.

This paper aims to compare sexual behaviour and risk and protective factors between samples of adolescents who have sex under the influence of alcohol and those who do not, and to determine predictors factors for having had sex under the influence of alcohol. We analysed differences between these two groups in sexual practices, attitudes towards HIV, subjective norms and HIV knowledge. Drawing on survey data collected from 1216 Spanish adolescents aged 14-18 (M = 15.92; SD = .76), a subset of 297 sexually experienced participants was selected. Of these, 117 reported having had sex under the influence of alcohol in the past six months (51% girls). Adolescents who combined sex and alcohol engaged more in vaginal sex, oral sex and anal sex than those who did not. Having had sex under the influence of alcohol in the past six months was associated with negative attitudes towards condom use, when there are obstacles on using them, and less consistent condom use. There were no differences in knowledge about STIs/HIV between both groups. Adolescents who combined sex and alcohol showed further characteristics associated with sexual risk. Preventive measures must address the particular characteristics of this risk group. Further evidence is need about alcohol effects on sexual behaviour.

The increase in the use of New Technologies in social relationships could be generating a new paradigm in social skills. Valid and reliable instruments to assess these changes are needed. The aim of this study is to analyze the psychometric properties of the Multidimensional Scale of Social Expression (EMES) in the assessment of social skills on the Internet and Social Networks. A total of 413 college students from the province of Alicante participated on this study. The scale was applied according to two contexts: Real and Internet/Virtual. High internal consistency was shown. The 12-factor structure found for the Virtual Context scale is similar to that of the original study. The scale had shown to be a good predictor of hours of Internet use. In conclusion, EMES-C is useful for assessing real context and Internet context social skills.

To analyze differences in health-related quality of life across weight categories based on body mass index in boys and girls aged 8 to 12 years old.A cross-sectional study with 678 schoolchildren aged between 8 and 12 years from the province of Alicante (Spain) was conducted. The scores on the dimensions of health-related quality of life, assessed by the Spanish version of the Child Health and Illness Profile-Child Edition, across the weight categories (according to the World Health Organization Child Growth Standards) and sex, were compared.Overweight or obesity was found in 28.2% and 15.3% of the sample, respectively. There were no statistically significant differences (p0.05) across the weight categories on the distinct dimensions of health-related quality of life.Children are unaware of the impact of obesity on quality of life. Interventions to increase knowledge of this issue are required.

Family-based drug use prevention: TheFamilias que Funcionan [Families that work]program..Familias que Funcionan[Families that work] is a family-based drug-use prevention program resulting from the adaptation to the Spanish context of the prestigious North-AmericanStrengthening Families Program 10-14. The program was applied at four secondary schools (N = 380 pupils) in Asturias (northern Spain). This article presents the results of the assessment of this application after a two-year follow-up, regarding its effectiveness in the reduction of drug use among adolescents and its effects on certain family risk factors. Consistent attendance in theFamilias que Funcionanprogram proved effective for reducing both rates (t= -2.73, p.05 and t= -4.58, p.005, for the 1- and 2-year follow-ups, respectively) of increase in adolescent drug use and some family risk factors.
