Fidelity of implementation of Reptes, an alcohol and cannabis selective prevention program for youngsters.

OBJECTIVE: Implementation fidelity is a key dimension in process evaluation but has been scarcely studied. Reptes is a selective alcohol and cannabis use prevention program performed in vulnerable young people (16-21 years) from different educational and leisure settings. The study aimed to describe the components of this program, its implementation fidelity, and satisfaction among participants and facilitators. METHOD: A descriptive cross-sectional study was conducted. Implementation fidelity was assessed in terms of adherence, dose, participant responsiveness, and quality of the intervention through self-reports completed by 15 facilitators and self-administered questionnaires by 99 youth from the 15 groups completing the program. RESULTS: 70.7% of the groups performed 30 of the 43 planned activities with high use of various teaching methods, except for Information and Communication Technology resources. Fidelity implementation was above 70%. 2/3 groups completed an acceptable intervention and 1/3 completed a qualified intervention. Satisfaction was higher than 7. CONCLUSIONS: Our results show high implementation fidelity and satisfaction compared with those from similar studies.

[Personality traits associated with the substance consumption in young people in a context of vulnerability]. / Rasgos de la personalidad asociados al consumo de sustancias en jóvenes en contexto de vulnerabilidad.

OBJECTIVE: To analyze the patterns of alcohol and cannabis consumption, and their associated factors, in young people aged 16 and 21 in a context of vulnerability. METHOD: Cross-sectional study based on a pre-test questionnaire from an evaluation study, administered to a convenience sample of 365 young people from Social Guarantee Programs (SGP), or who attended activities of community entities from disadvantaged neighborhoods in Barcelona. Dependent variables were experimental, regular, and problematic alcohol and cannabis consumption, while independent variables were impulsivity, sensation seeking, expectations, and beliefs regarding drug use, social skills, and contextual variables. Associations were established using multivariate logistic regression models. RESULTS: The prevalence of intensive alcohol consumption (24.2% for binge drinking and 33.3% for binge drinking) and experimental (51.1%) and problematic cannabis use (12.9%) was higher in SGP students than entity youth. Likewise, they presented higher scores on the impulsivity scales, sensation seeking, expectations and beliefs favorable to alcohol consumption. In general, the prevalence of experimental alcohol consumption was higher in girls than in boys. Regular binge drinking was associated with intense sensations seeking (adjusted odds ratio [aOR]: 1.06; 95% confidence interval [95%CI]: 1.01-1.12), while attending SGP was associated with problematic cannabis use (aOR: 2.73; 95%CI: 1.26-5.89). Positive expectations to alcohol and cannabis use were associated with problematic substance use. CONCLUSION: Individual risk, linked to the higher risk trajectories of SGP students, is associated with a higher problematic consumption of alcohol and cannabis than in young people from community entities exposed to an environmental risk of high frequency of consumption.

Detection of the Brachyspina mutation in Uruguayan Holstein cows using real time PCR and melting curve analysis / Detecção da mutação da Brachyspina em vacas Holandês Uruguaias usando PCR em tempo real e análise da curva de fusão

ABSTRACT: Brachyspina syndrome (BS) is a rare monogenic autosomal recessive hereditary disorder of the Holstein Fresian breed caused by a deletion of 3.3Kb in the Fanconi anemia complementation group I (FANCI) gene on BTA-21, which leads to a frame-shift and premature stop codon. Some of the consequences of BS are the reduction of the fertility rate and milk production. This study developed a simple, sensitive, rapid cost- effective assay method based on real time PCR and melting curve analysis for the detection of BS carrier animals. Sixty-eight normal homozygous and four heterozygous carrier genotypes were detected and confirmed through traditional PCR- electrophoresis analysis. We concluded that the assay we have developed proved to be a reliable, highly precise and low-cost tool, which could be used to monitor the presence of the BS mutation in uruguayan Holstein breed.

RESUMO: A síndrome de Brachyspina (BS) é um defeito hereditário monogênico autossômico recessivo raro da raça Holstein Friesian causado por uma exclusão de 3,3 KB no gene FANCI localizado no cromossomo bovino 21, o que leva a um deslocamento de quadro e um códon de parada prematuro. Uma consequência da BS é a eficiência de reprodução reduzida e a produção de leite. O objetivo deste estudo foi o desenvolvimento de um método simples, rápido e sensível, baseado em PCR em tempo real e análise da curva de fusão para identificar animais portadores de BS. Sessenta e oito genótipos homozigotos normais e quatro heterozigotos foram detectados e confirmados através da análise tradicional de PCR e electophorese. Concluímos que o novo método é uma ferramenta confiável, altamente precisa e de baixo custo, que poderia ser usado para monitorar a presença da mutação BS na raça Holandês uruguaia.

Social Factors Associated with the Effectiveness of a Spanish Parent Training Program-An Opportunity to Reduce Health Inequality Gap in Families.

Parent training programs (PTPs) have been used extensively in Anglo-Saxon countries, but less so in Southern Europe. Several characteristics of families have been linked to effective parenting and positive development of children, but few studies have examined the social determinants of the effectiveness of PTPs. The Parenting Skills Program for families (PSP) is a PTP from Spain. This study aimed to identify the social characteristics (sex, age, country of birth, marital status, educational level, and employment status) of parents that determine the success of the PSP in relation to social support, parenting skills, parental stress, and negative behaviors among children. A quasi-experimental study with a prepost design with no control group was used. We conducted a survey before (T0) and after the intervention (T1). Sample size was 216. We fit multiple logistic regression models. Parenting skills increased more among parents with a lower educational level. Parents' stress decreased more among parents who had a lower educational level, were unemployed, and were men. Social support increased among parents who were younger, unemployed, or non-cohabiting. We found no significant differences in the effect on children's negative behaviors according to the social factors evaluated. The PSP is effective for socioeconomically diverse families, but the success differs according to the parents' social profile. Unlike most previous studies, the results were better among more socially disadvantaged people, highlighting the potential of this kind of intervention for reducing the social inequality gap between groups.

Salud comunitaria confinada: reflexiones y experiencias desde la salud pública local / Confined community health: reflections and experiences from the local public health

Este artículo pretende compartir las reflexiones sobre la acción comunitaria en que la Agència de Salut Pública de Barcelona ha estado involucrada en la emergencia de COVID-19. El trabajo realizado puede ordenarse en tres etapas, frecuentemente solapadas: detectar necesidades o problemas, e informar; contactar con las personas participantes y agentes territoriales para valorar qué hacer y cómo hacerlo; y adaptar las intervenciones a la "nueva normalidad" y generar respuestas con los activos comunitarios a las necesidades detectadas. Los problemas emergentes incluyeron: no poder realizar el confinamiento (por falta de casa, condiciones materiales, vivir en situación de violencia); brecha digital (falta de conocimientos, dispositivos, acceso a Wifi); mayor exposición al COVID-19 en los trabajos esenciales pero precarizados, feminizados y racializados (cuidados, limpieza, alimentación), frecuentes en los barrios en que trabajamos; barreras idiomáticas y culturales para seguir las recomendaciones; pérdida de empleo; ingresos insuficientes para cubrir necesidades básicas; dificultades de conciliación; aislamiento social; y deterioro de la salud emocional provocado por la situación. Durante el proceso, algunas intervenciones se adaptaron para continuar de forma telemática, y se intentaron cubrir las necesidades primarias sobre conocimientos y dispositivos de algunas personas participantes a través de las redes solidarias y recursos existentes. La acción comunitaria en salud, desde una mirada crítica, interseccional y local, mediante trabajo intersectorial y la participación de la comunidad, puede contribuir a: facilitar una respuesta adaptada al contexto en caso de crisis sanitaria y mitigar los efectos derivados de esta crisis económica y social

This paper aims to share the reflections related to the community actions in which the Agència de Salut Pública de Barcelona has been involved during the emergency of COVID-19. The tasks carried out can be arranged in three stages, frequently overlapping: detection of needs and problems; contact with key stakeholders to assess what to do and how to do it; adaptation of the interventions to the "new normal" and generation of new responses. The emerging problems included: not being able to do the confinement (due to homelessness, material conditions, living in a situation of violence); digital gap (lack of knowledge, devices, access to Wifi); greater exposure to COVID-19 in the essential but precarious, feminized and racialized jobs (care, cleaning, food shops) that are the most frequent in the neighborhoods in where we work; language and cultural barriers that preclude to follow recommendations; to lose employment; insufficient income to cover basic needs; social isolation; and the deterioration of emotional health caused by the situation. During the process, some interventions were adapted to be delivered on-line. Solidarity networks and local resources were key to meet basic needs, but also other needs related to lack of digital knowledge or device. Community action in health, from a critical, intersectional and local perspective, and with intersectoral work and community participation, can contribute to: facilitate a contextualized response in the event of a health crisis; mitigate the effects derived from its economic and social crisis

Morphological configuration and topography of the brain arterial supply of the one-humped camel ( Camelus dromedarius, Linnaeus 1758) / Configuración morfológica y topografía del suministro arterial del encéfalo del camello de una joroba ( Camelus dromedarius, Linnaeus 1758)

This study investigated the anatomy of the arteries of the brain, including the arterial circle of the brain, its branches and junctions, in five camel (Camelus dromedarius, Linnaeus 1758) following intravascular injection of colored latex via common carotid artery. The course and distribution of the arterial supply to the brain was described and morphological analysis was made. The basilar artery contributed to the blood supply of the brain in the camel in contrast to the situation in other Artiodactyla order.

En presente estudio se analizó la anatomía de las arterias del encéfalo en cinco camellos (Camelus dromedarius, Linnaeus 1758). Después de administrar una inyección intravascular de látex coloreado en la arteria carótida común se estudiaron las arterias incluyendo al círculo arterial del cerebro, sus ramas y uniones. Fueron descritos en detalle el curso y la distribución del suministro arterial al encéfalo y se realizó un análisis morfológico. La arteria basilar contribuyó al suministro de sangre del encéfalo del camello, diferenciando este aspecto en otras especies de Artiodactyla.

Effectiveness of a parent-training program in Spain: reducing the Southern European evaluation gap / Efectividad de un programa de educación parental en España: reducir la brecha en cuanto a evaluación en el sur de Europa

Objective: We implemented and evaluated the Parenting Skills Program for families in Spain 1) to examine differences in parenting skills, social support, children's behaviours and parental stress pre, immediately post and six months post intervention and 2) to identify mechanisms by which the intervention is related to changes in the four outcomes examined. Methods: Quasi-experimental study design with pre (T0), post (T1), a follow-up (T2) and no control group, complemented by a qualitative study was used. The outcome variables were social support, parenting skills, parental stress and children's behaviours. 216 parents completed pre and post questionnaire and 130 parents the follow-up questionnaire. 39 professionals and 34 parents participated in 17 interviews and 5 discussion groups. Results: Compared with T0, all four outcomes improved significantly at T1. 76% of the participants improved parenting skills and 61% social support. 56% reduced children's negative behaviours and 66% parental stress. All outcomes maintained this significant improvement at T2. Parents and professionals describe different changes in parents' parenting skills, stress and social support after participation in the PSP, and in their children's behaviours. Some subcategories emerged after analysing parents' and professionals' discourses. Conclusions: This study describes positive parenting effects on participants of a parent-training program in Spain, which is a country where implementation and evaluation of these kind of interventions is an incipient issue

Radial shape discrimination testing for new-onset neovascular age-related macular degeneration in at-risk eyes.

We investigated the performance of the handheld radial shape discrimination (hRSD) test in detecting the development of neovascular AMD (nAMD) in a prospective, longitudinal, observational study. Patients diagnosed with unilateral nAMD, with no nAMD in the other eye (the study eye, SE), completed the hRSD test on consecutive, routine clinic visits up to a maximum of 12, or until they were diagnosed with nAMD in the SE based on slit-lamp biomicroscopy and spectral-domain OCT assessment, with fluorescein angiography confirmation. Masked grading was carried out to confirm the diagnosis of nAMD, and to ensure no cases of nAMD were missed. Receiver operating characteristics (ROC) analysis was used to explore the diagnostic performance of the hRSD test relative to clinical diagnosis. Data were available from 179 patients of whom 19 (10.6%; "converters") developed nAMD in the SE. The mean hRSD threshold at conversion was -0.47 (95% CI -0.38 to -0.55) logMAR compared to -0.53 (-0.50 to -0.57) logMAR in 160 non-converters. hRSD threshold in the converters began to decline 190 days before diagnosis of nAMD. The ROC curve demonstrated that at an hRSD cut-off of -0.60 logMAR, sensitivity was 0.79 (0.54-0.94) with a specificity of 0.54 (0.46-0.62); positive and negative predictive values were 0.16 and 0.96 respectively. We conclude that the hRSD test has moderate sensitivity for detecting the earliest stages of nAMD in the at-risk fellow eyes of patients with unilateral nAMD, compared to clinical diagnosis. Given its relative inexpensiveness, ease of use and the inherent connectivity of the platforms it can be presented on, it may have a role in early detection of nAMD in the population at large.

[What works in selective prevention of alcohol and cannabis use among vulnerable young people?] / ¿Qué funciona en la prevención selectiva del consumo de alcohol y cánnabis en jóvenes vulnerables?

OBJECTIVE: Selective prevention tackle vulnerable factors associated to problem consumption and social exclusion. There are few effective programs in our context. Study aims were first to identify selective programs of alcohol and cannabis consumption for youths between 16-21, and second, to review intervention, evaluation and effects quality. METHODS: MEDLINE, PubMed, Google academics, EDDRA, SAMHSA, PBE and recommendations of PND were reviewed. Inclusion criteria were: 1) English/ Spanish programs, 2) publications <10 years, 3) target population 16- 21 years old 4) alcohol/ cannabis psicoeducational or socioeducational programs, 5) selective or selective/indicated programs and 6) evaluated programs. The description and quality of the intervention, its evaluation methods, and the presentation of its effects were assessed according to 20 criteria emerged from different recommendations. RESULTS: Fourteen programs followed the inclusion criteria, 10 of followed minimum quality intervention and evaluation criteria, however only 5 shown significant effects. Effective programs tackled negative emotions associated to consumption, promoted skills to cope it and reduce frequency of alcohol consumption, but rarely cannabis consumption. CONCLUSIONS: There are few selective prevention programs, and different studies shown that they have intervention or evaluation weaknesses, but mostly about program effects. The most effective are: PreVenture, The Climate Schools: Alcohol and Cannabis Course, Programa TND, Keepin' it REAL and Weekend is coming.

Arterial irrigation of the head and neck of the pampas deer (Ozotoceros bezoarticus, Linnaeus 1758).

The pampas deer (Ozotoceros bezoarticus) is a medium-sized deer that weighs 20-40 kg. Historically, it was a widely distributed species that occupied a wide range of open habitats, including pastures, pampas, and Brazilian savanna. However, it is currently considered to be a species at risk of extinction. Anatomical descriptions of the arterial supply are very useful when working with exotic mammals. Knowledge of the locations, the distribution pattern, and the anatomical relationships of the arteries is required when performing any intervention. The objective of this research was to describe the normal arterial distribution pattern in the head and neck of this species. The divisions of the common carotid arteries, to which branches of the vertebral arteries are attached, irrigate the head and cranial parts of the neck. The arterial distribution pattern in the head and neck of the pampas deer was found to be similar to that described for other cervids and bovines but showed important differences from that for the ovine. The pampas deer had a bicarotid trunk, in contrast to other cervids. With regard to domestic animals, the lack of a fully developed internal carotid artery and the marked presence of a linguofacial trunk mean that it resembles the arterial distribution described for bovines.

La priorización comunitaria en el programa Barcelona Salut als Barri / Community prioritization in Barcelona Salut als Barris program

Priorizar es el proceso de selección y ordenación de las necesidades en salud identificadas tras el diagnóstico de necesidades y activos en salud de una comunidad. La valoración de las necesidades en salud se ha reforzado con la perspectiva comunitaria, lo que aporta múltiples beneficios: sensibiliza y empodera a la comunidad sobre su salud, fomenta el apoyo mutuo entre sus integrantes y promueve su protagonismo haciéndola corresponsable del proceso de mejora de su propia realidad. El objetivo de esta nota es describir el modelo de priorización de Barcelona Salut als Barris, estrategia de salud comunitaria liderada por la Agencia de Salud Pública de Barcelona para promover la equidad en salud en los barrios más desfavorecidos de la ciudad (AU)

Prioritizing corresponds to the process of selecting and managing health needs identified after diagnosing the community's health needs and assets. Recently, the health needs assessment has been reinforced with the community perspective, providing multiple benefits: it sensitizes and empowers the community about their health, encourages mutual support among its members and promotes their importance by making them responsible for the process of improving their own reality. The objective of this paper is to describe the prioritization of Barcelona Salut als Barris, a community health strategy led by the Barcelona Public Health Agency to promote equity in health in the most disadvantaged neighborhoods of the city (AU)

Aspectos macroanatómicos del corazón del carpincho ( Hydrochoerus hydrochaeris ) / Macroanatomical characteristics of the heart of the carpincho ( Hydrochoerus hydrochaeris )

RESUMEN: La información disponible sobre el aparato cardiovascular del carpincho (Hydrochoerus hydrochaeris) es escasa. El objetivo general de este estudio fue describir la anatomía cardíaca de esta especie. Se utilizaron 6 animales adultos y 5 neonatos, libres de patologías del aparato cardiovascular. El método de estudio de los animales fue la disección simple. El corazón del carpincho estaba ubicado desde el segundo espacio intercostal hasta la sexta costilla. El ligamento frenicopericárdico unía el pericardio fibroso al esternón y al diafragma. El tubérculo intervenoso era de escaso desarrollo. En la aurícula derecha se encontraban escasos músculos pectinados. Los músculos papilares derechos presentaban entre ellos trabéculas septomarginales. Las trabéculas carnosas presentaban un marcado desarrollo sobre la pared marginal del ventrículo derecho. También había grandes trabéculas carnosas sobre la pared septal, que sin embargo era algo más lisa. Los músculos papilares izquierdos eran dos, situados opuestos uno al otro y sobre la pared septal. Ambos eran simples y emitían cuerdas tendinosas hacia ambas cúspides de la válvula atrioventricular izquierda. Las trabéculas carnosas del ventrículo izquierdo eran menos numerosas. Entre ambos músculos papilares existía una gran trabécula carnosa que ocupaba gran parte de la extensión dorsoventral de la pared septal del ventrículo izquierdo. De ambas arterias coronarias, la arteria coronaria izquierda que surgía del seno coronario izquierdo de la aorta era la más importante, de mayor tamaño y de mayor distribución, encargándose de la irrigación de la mayoría del territorio cardíaco. La rama interventricular paraconal se dirigía por el surco interventricular paraconal y terminaba sobre el margen ventricular derecho anastomosándose con la rama interventricular subsinusal que venía por el surco del mismo nombre. Con otras técnicas, es necesario realizar estudios histológicos, semiológicos y fisiológicos en el corazón de esta especie para entender mejor su anatomía y fisiología.

SUMMARY: The available information on the cardiovascular apparatus of the capybara (Hydrochoerus hydrochaeris) is scarce. The general objective of this study was to describe the cardiac anatomy of this species. Six adult animals and five newborns were used; all were free of cardiovascular system pathologies. The method of study of the animals was simple dissection. The heart of the capybara was located from the second intercostal space to the sixth rib. The frenicopericardial ligament attached the fibrous pericardium to the sternum and the diaphragm. The intervenous tubercle was poorly developed. In the right atrium, there were few pectinated muscles. The right papillary muscles had septomarginal trabeculae among them. The carnous trabeculae showed a marked development on the marginal wall of the right ventricle. There were also large, carnous trabeculae on the septal wall, which was somewhat flatter. The left papillary muscles were two, located opposite each other and on the septal wall. Both were simple and sent tendinous cords to both cusps of the left atrioventricular valve. Carnous trabeculae of the left ventricle were less numerous. Between both papillary muscles there was a large carnous trabecula that occupied much of the dorsoventral extension of the septal wall of the left ventricle. Of both coronary arteries, the left coronary artery that emerged from the left coronary sinus of the aorta was the most important, with larger size and greater distribution. The paraconal interventricular branch was directed through the paraconal interventricular groove and terminated on the right ventricular margin anastomosing with the subsinusal interventricular branch that came through the groove of the same name. With other techniques, it is necessary to perform histological, semiological and physiological studies in the heart of this species to better understand its anatomy and physiology.

Performance, usability and comparison of two versions of a new macular vision test: the handheld Radial Shape Discrimination test.

BACKGROUND: Central vision, critical for everyday tasks such as reading and driving, is impacted by age-related changes in the eye and by diseases such as age-related macular degeneration. The detection of changes in macular function is therefore important. The Radial Shape Discrimination (RSD) test measures the threshold at which distortions in a radial frequency pattern can be detected and there is evidence that it is more sensitive to macular pathology than visual acuity (VA). It also provides a more quantitative measure of macular function than the commonly available Amsler grid. Recently, handheld versions of the test (hRSD) in which stimuli are presented on mobile devices (e.g., Apple iPod Touch, iPhone) have been developed. We investigated the characteristics of the hRSD test in healthy participants. METHODS: Data were collected using both three-alternative forced choice (3AFC) and 4AFC versions of the hRSD test, presented on an Apple iPod Touch. For the 3AFC version, data from a single test session were available for 186 (72 male; mean ± SD age 42 ± 17y; range 16-90y) healthy participants. Test-retest data were available for subgroups of participants (intra-session: N = 74; tests approximately 2 months apart: N = 30; tests 39 months apart: N = 15). The 3AFC and 4AFC versions were directly compared in 106 participants who also completed a usability questionnaire. Distance and near VA and Pelli Robson Contrast Sensitivity (CS) data were collected and undilated fundoscopy performed on the majority of participants. RESULTS: Mean (±SD) 3AFC hRSD threshold was -0.77 ± 0.14 logMAR, and was statistically significantly correlated with age (Pearson r = 0.35; p < 0.001). The linear regression of hRSD threshold on age had a slope of +0.0026 compared to +0.0051 for near VA (which also correlated with age: r = 0.51; p < 0.001). There were no statistically significant differences in hRSD thresholds for any of the test-retest subgroups. We also observed no statistically significant difference between 3AFC (-0.82 ± 0.11 logMAR) and 4AFC (-0.80 ± 0.12 logMAR) hRSD thresholds (t = 1.85, p = 0.067) and participants reported excellent test usability with no strong preference expressed between the 3AFC and 4AFC versions of the test. DISCUSSION: The 3AFC hRSD thresholds we report are consistent with a number of previous studies, as is its greater stability in ageing compared to VA. We have also shown that in the absence of pathology, thresholds are stable over short and long timescales. The 4AFC thresholds we have reported provide a baseline for future investigations, and we have confirmed that 3AFC and 4AFC thresholds are similar, providing a basis of comparisons between studies using the different versions. As the hRSD test is easy to use and relatively inexpensive, clinical studies are now required to establish its ability to detect and monitor macular pathologies.

Efecto de una intervención de promoción de la parentalidad positiva sobre el estrés parental / How an Intervention to Promote Positive Parenting Affects Parental Stress / Efeito de uma intervenção de promoção da parentalidade positiva sobre o estresse parental

Fundamentos: los programas de educación parental, promotores de la parentalidad positiva, reducen el estrés parental. En España y Latinoamérica son escasas las evaluaciones que evidencian dichos efectos y en ningún caso exploran los predictores de éxito. Este estudio analiza los cambios producidos por el "Programa de desarrollo de habilidades parentales para familias" (PHP), basado en la educación parental y promovido por enfermeras comunitarias sobre el estrés parental, e identifica los factores sociodemográficos asociados a una mayor reducción de estrés. Métodos: se recogió información sociodemográfica de 257 participantes, antes de la intervención y de estrés parental antes y después de esta. Se empleó la versión española de Parental Stress Scale. Se aplicaron test no paramétricos y una regresión logística binaria. Resultados: el análisis bivariado identificó reducción del estrés parental para todas las categorías de las variables predictoras. El análisis multivariado mostró que los hombres, las personas con menor nivel de estudios y las desempleadas presentaron mayor probabilidad de reducir el estrés. Conclusiones: el PHP es una intervención efectiva para reducir el estrés parental en diferentes grupos poblacionales. Este estudio contribuye a reforzar los incipientes hallazgos de estudios internacionales, y a dar respuesta al vacío de los países latinos, en cuanto al papel de los determinantes sociales como predictores de la reducción del estrés parental generados por los programas de educación parental.

Fundamentals: Parental education programs, promoting positive parenting, reducing parental stress. Assessments that demonstrate these effects are rare in Spain and Latin America and in no case do they explore predictors of success. This study analyzes the changes in parental stress brought about by the "Parenting Skills Development Program for Families" (PSP), which is based on parental education, promoted by community nurses, and identifies the socio-demographic factors associated with added stress reduction. Method: Sociodemographic information was collected on 257 participants prior to the intervention and on parental stress before and after the intervention. The Spanish version of the Parental Stress Scale was used. A nonparametric test and binary logistic regression were applied. Results: A bivariate analysis identified a reduction in parental stress in all the categories of predictor variables. A multivariate analysis showed that men, as well as persons with lower levels of education and unemployed persons had more likelihood of reducing stress. Conclusions: PSP is an effective intervention to reduce parental stress in different population groups. This study helps to strengthen the incipient findings of international research and to respond to the void in Latin American countries concerning the role of social determinants as predictors of parental stress reduction generated through parental education programs.

Evaluación de un programa piloto promotor de habilidades parentales desde una perspectiva de salud pública / Evaluation a parenting skills pilot programme from a public health perspective

Objetivo: Evaluar el proceso y los resultados de la fase piloto del Programa de desarrollo de habilidades parentales para familias (PHP), una estrategia de promoción de la parentalidad positiva basada en la evidencia y aplicable en contextos comunitarios y socioeducativos. Métodos: Diseño cuasiexperimental antes-después sin grupo control para la evaluación de la fase piloto del PHP implementada entre octubre de 2011 y junio de 2013 en Barcelona. Se condujeron 11 grupos en los que participaron 128 padres y madres y 28 profesionales. La intervención consistió en 10 u 11 sesiones. La información se recogió con cuestionarios a padres y madres y entrevistas en profundidad, individuales o grupales, a los/las profesionales. Las habilidades parentales se recogieron mediante un cuestionario con seis dimensiones. Se comparó la situación inmediatamente antes (T0) e inmediatamente después (T1) de la intervención. Resultados: El número de participantes en T1 se redujo a 83 (retención del 64,8%). El grado de satisfacción de los participantes con diversos aspectos del programa fue muy alto. Sobre una puntuación máxima de 10, la satisfacción de las personas moderadoras fue de 8,7. Se identificaron aspectos clave y áreas de mejora para el futuro de la intervención. En el análisis cuantitativo se observaron mejoras en todas las dimensiones de habilidades parentales que fueron consistentes con los resultados del análisis cualitativo. Conclusiones: Los resultados de la fase piloto de este programa apuntan a que una intervención universal de educación parental puede mejorar el bienestar de padres y madres (AU)

Objective: To evaluate the process and the results of the pilot phase of the Parenting skills development programme for families (PSP), an evidence-based strategy to promote positive parenting skills in socio-educational and community settings. Methods: Before-after quasi-experimental design without a control group for the evaluation of the pilot phase of the PSD carried out in Barcelona (Spain) between October 2011 and June 2013. Eleven groups were established with the participation of 128 parents and 28 professionals. The intervention consisted of 10 or 11 sessions. Information was collected through questionnaires for parents and in-depth individual or group interviews for professionals. Parenting skills were identified through a questionnaire with six dimensions. The situation before the intervention (T0) and immediately after (T1) was compared. Results: In T1 the number of participants decreased to 83 (retention=64.8%). Participants showed a high level of satisfaction with different dimensions of the program. On a maximum score of 10, the satisfaction of professionals was 8.7. Several key aspects and areas for improvement were identified for the future of the intervention. The quantitative analysis revealed improvements in all parenting skills dimensions and these improvements were consistent with the results of the qualitative analysis. Conclusions: The results of the pilot phase of this program suggest that a universal intervention on parenting skills can improve wellbeing among parents (AU)
