Psychometric adaptation of the Spanish version of the Brief Pittsburgh Sleep Quality Index in adolescents.

OBJECTIVE: Good sleep quality is essential for adolescent health, yet sleep difficulties persist in this age group. The 6-item Brief Pittsburgh Sleep Quality Index (B-PSQI) was recently developed to improve sleep quality assessment, however, its validity in adolescents remains unexplored. This study examined the B-PSQI's psychometric properties in Spanish adolescents and adapted the scoring method to age-specific sleep recommendations. METHODS: A cross-sectional study involving 1,065 adolescents (15-17 years; 56.8% female) was conducted in public high schools. Sleep quality was measured using the B-PSQI, the Insomnia Severity Index (ISI), the short Patient-Reported Outcomes Measurement Information System (PROMIS), and the Epworth Sleepiness Scale (ESS). Additionally, depression and anxiety were assessed using the Depression, Anxiety, and Stress Scales. Reliability, validity, and measurement invariance were analyzed. RESULTS: The B-PSQI global scores were 4.5 (SD = 1.9) for the original scoring method and 5.4 (SD = 2.8) for the age-adjusted. The age-adjusted B-PSQI showed satisfactory reliability (ω = 0.84) and concurrent, convergent, and discriminant validity (ISI rS = 0.67; PROMIS rS = 0.71; anxiety rS = 0.40; depression rS = 0.42; ESS rS = 0.29). Adequacy for one-factor structure (χ2(4) = 53.9; CFI = 0.97; TLI = 0.92; RMSEA = 0.108; SRMR = 0.05) and invariance across sexes were supported. Both B-PSQI scoring methods showed similar psychometric properties, but the original yielded a higher percentage of poor sleepers (43.1%; cutoff ≥5) than the age-adjusted version (41.9%; cutoff ≥6). CONCLUSIONS: Findings suggest that the B-PSQI is a valid and reliable measure to assess adolescent sleep quality. Its scoring can be adjusted to provide age-specific criteria for good sleep. The B-PSQI has potential utility for screening sleep problems and facilitating overall health promotion in adolescents.

Effectiveness of the Brief Guided Self-Change Therapy Combined with Varenicline under "Real-Life" Conditions and Mediators for Smoking Cessation.

Background: Brief therapies have proven to reduce tobacco cost-effectively, however, unsuccessful quit attempts remain notable in real-life conditions, and the underlying mechanisms of treatment success are still unclear. Objectives: We aimed to analyze the effectiveness of the Guided Self-Change (GSC) therapy combined with varenicline (VAR+T) in public health services against varenicline alone (VAR), and to identify mediators of treatment outcomes. We conducted a two-arm quasi-experimental study with 126 treatment-seeking smokers (age=57.3±9.1 years; 59.5% women). Before treatment, and at weeks 12 and 24, we assessed tobacco use and five potential mediators: withdrawal, craving, motivation to quit, anxiety, and depression. Results: Only 25% of participants adhered to varenicline prescription, and 54% to GSC therapy. VAR+T group showed a greater proportion of abstainers compared to VAR group at week 12 (75% vs 57.4%; φc=0.21) and week 24 (62.9% vs 52.5%; φc=0.10). When controlling for weeks taking varenicline, motivation showed a significant indirect effect over abstinence rates in VAR+T compared with VAR (a1b1=1.34; 95%CI=0.04, 5.03). Conclusions: The GSC effectiveness seems to increase motivation which in turn contributes to reducing tobacco use. The implementation of GSC therapy in public health services could minimize treatment duration and increase smoking abstinence in 'real-life' conditions where varenicline adherence remains low.

Profile of chronic pain patients with opioid withdrawal syndrome according to psychological factors: a Latent Class Analysis.

OBJECTIVE: Withdrawal syndrome stands out as the strongest risk factor for Prescription Opioid-Use Disorder (POUD) and is related to psychological and pain impairment in chronic pain population. This study aimed to identify profiles of chronic pain patients with opioid withdrawal based on psychological factors, and to explore the association between the classes and demographic, clinical, and substance use variables. METHOD: This cross-sectional descriptive study involved 391 patients, 221 of them with interdose withdrawal (mean age=57.91±13.61 years; 68.3% female). Latent Class Analysis (LCA) and bivariate and logistic regression analyses were performed. RESULTS: Two latent classes were identified (BIC=4020.72, entropy=0.70, LRTs p<0.01): Withdrawal syndrome with No Psychological Distress (WNPD; 45.2%, n=100) and Withdrawal syndrome with Psychological Distress (WPD; 54.8%, n=121). The WPD class was more likely to experience craving, anxiety, and depression, and to report higher levels of pain intensity and interference (p<0.01). Patients in this class were younger, visited a higher number of specialists, and showed higher rates of high-dose opioid use, misuse, moderate-severe POUD, and tobacco and anxiolytics use (p<0.05). Only moderate-severe POUD (OR=2.64) and tobacco use (OR=2.28) increased the risk of WPD class membership. CONCLUSIONS: Although it is common for chronic pain patients to experience withdrawal symptoms during opioid treatment, more than a half of the participants reported concomitant psychological distress. Establishing differential profiles can help to improve withdrawal syndrome management during the treatment of chronic pain with opioids.

Estilos educativos percibidos por deportistas consumidores de tabaco y cánnabis / Perceived Education Styles by Athletes Consumers of Tobacco and Cannabis / Estilos educativos percebidos por esportistas consumidores de tabaco e cannabis

Objetivo. Conocer las diferencias en los estilos educativos parentales percibidos por deportistas consumidores de tabaco y cánnabis. Método. La muestra fue de 502 deportistas españoles con una edad media de 27.76 (DE = 9.11). Para analizar los estilos educativos parentales se aplicó el Test Autoevaluativo Multifactorial de Adaptación Infantil (TAMAI); y para excluir del estudio a los participantes aquiescentes se utilizó la Escala de Oviedo de Infrecuencia de Respuesta (INF-OV). Se realizó un estudio descriptivo, transversal. La selección de la muestra se llevó a cabo en línea a través de Google Forms. Resultados. Los deportistas que no consumen tabaco (t = -2.53, p < 0.05) ni cánnabis (t = -3.26, p < 0.01) obtuvieron mayor proteccionismo del padre en la prueba t de student. Los deportistas consumidores de cánnabis, en cambio, obtuvieron mayor restricción del padre (t = 2.40, p < 0.05) en la prueba t de student. En la regresión logística binaria, se identificó una relación entre el no consumo de tabaco diario (OR = 0.39, p < 0.01) y el no consumo de cánnabis (OR = 0.74, p < 0.01) con el proteccionismo paterno. Conclusión. El proteccionismo paterno puede ser un factor protector en el consumo de tabaco y cánnabis en deportistas, mientras que la restricción paterna puede ser un factor que facilite el consumo de cánnabis.

Objective. To know the differences in perceived parental education styles according to athletes who are consumers of tobacco and cannabis. Method. The sample consisted of 502 athletes from Spain with an age range of 27.76 (DT = 9.11). In order to measure the parental education styles, the "Multifactor Self-Assessment Test of Child Adjustment" (TAMAI) was administered; to measure the acquiescence, the Oviedo Scale of Infrequency of Response (INF-OV)was administered. The study was a cross-sectional descriptive study and it was conducted online through Google Forms. Results. Athletes who do not consume tobacco (t = -2.53, p < 0.05) and cannabis (t = -3.26, p < 0.01) had greater levels of father protectionism in independent samples t test. Moreover, athletes who were cannabis consumers scored greater levels of father restriction (t = 2.40, p < 0.05) in independent samples t test. On the other hand, more father protectionism demonstrated a relationship with not consuming tobacco (OR = 0.39, p < 0.01) or cannabis (OR = 0.74, p < 0.00). Conclusion. The father protectionism could be a protective factor with regard to consumption of tobacco and cannabis in athletes. Furthermore, father restriction could be a negative factor that may increase cannabis consumption in athletes.

These data show the effectiveness and need of preventing the emergence of childhood social rejection and associated diseases in school setting.

Alimentación de la ascidia Ecteinascidia turbinata (Ascidiacea: Perophoridae) en dos áreas de manglar de Cuba

Diet of the ascidian Ecteinascidia turbinata (Ascidiacea: Perophoridae) in two mangrove areas of Cuba. Stomach contents of 88 zooids of Ecteinascidia turbinata Herdman 1880 and the qualitative and quantitative composition of phytoplankton in the water column were studied in Santa Fe (North Coast of Havana) and Punta del Este (SW of Cuba). We identified 59 microalgal species and four tintinnids in the stomachs. Cell size was 75-165 µm in length and 2-105 µm in width. There were not significant differences in microalgal diversity in the water column in the two locations. In both locations, the diatoms had the largest number of species and individuals in stomachs and water. In Santa Fe, dinoflagellate biomass was larger in water and stomach contents, while in Punta del Este the contribution of each group to the stomach content was similar to that of the water column. This species filters in a constant and irregular way during the day, independently of food availability. Rev. Biol. Trop. 55 (2): 499-507. Epub 2007 June, 29.

Se estudiaron los contenidos estomacales de 88 zooides de Ecteinascidia turbinata Herdman 1880 y la composición cualitativa y cuantitativa del fitoplancton en la columna de agua en Santa Fe (Litoral Norte de la Habana) y Punta del Este (SW de Cuba). En el contenido estomacal de la ascidia se identificaron 59 especies de microalgas y cuatro tintínidos. El tamaño de las células varió entre 75 y 165 µm de largo y de 2 a 105 µm de ancho. No se encontraron diferencias significativas en la diversidad de especies de microalgas en la columna de agua de las dos localidades. Las diatomeas tuvieron la mayor cantidad de especies y el mayor número de individuos, tanto en los estómagos como en la columna de agua en ambas localidades. La biomasa de dinoflagelados en Santa Fe fue mayor en agua y estómagos. En Punta del Este el aporte de cada grupo al contenido estomacal es similar al encontrado en la columna de agua. Esta especie filtra de forma constante e irregular durante las 24 horas del día, independientemente de la disponibilidad de alimento.

Distribución y abundancia de la ascidia Ecteinascidia turbinata (Ascidiacea: Perophoridae) en Cuba / Distribution and abundance of the ascidian Ecteinascidia turbinata (Ascidiacea: Perophoridae) in Cuba

Permanently submerged mangrove roots (Rhizophora mangle) are the main habitat of the ascidian Ecteinascidia turbinata in Cuba. It was occasionally found on black coral (Antiphates caribeana) between 22 and 38 meters deep. This species exhibits a wide distribution in all the mangrove keys surrounding the Island of Cuba but does not occur in riparian or fringing mangroves. Populations of this species are abundant in Cuba: in 75% of the 58 localities sampled the species was present and in 57% more than 50% of the roots held at least one colony. The highest colony densities were found in the northern coast of Pinar del Rio province with values near one colony per lineal meter of mangrove root. We found the highest density (1.46 col/m) and greatest biomass at Jutías Key, with values between 25 and 660 g/m. The average of wet biomass in the studied mangroves was 73.63 g/m.
