Scientific literature has shown contextual factors that predict youth development, and family variables are the most important ones. In this study, we propose a model that explains the relation between family variables (relationship with parents and family activities) and Personal Positive Youth Development (assessed through Life satisfaction, Interiority, and Self-control), across different cultures. We recruited 2867 adolescents aged 12-18 years (52% female) from three countries: Spain, Mexico, and Peru. They completed an anonymous questionnaire. We run exploratory and confirmatory factor analyses, and structural equation modelling, testing for invariance across countries and sexes. In all subsamples, positive family relationships were associated with adolescents' Life Satisfaction. In addition, time invested on family activities was associated with Interiority and with Self-control. However, some differences across cultures and sex were found in the specific associations. Theoretical and practical implications are discussed regarding how to improve adolescent development through family life.

Background Couple relationship distress is common and associated with poor physical, psychological, and relational outcomes for both partners. Emotionally Focused Therapy for couples (EFT) is a short-term structured approach based on attachment theory that integrates a humanistic, experiential approach to restructuring emotional experience and a systemic structural approach to restructuring interactions. This model has been shown to be an effective treatment for couple distress. The supporting research, however, has only been conducted with English-speaking couples. Despite Spanish being the second-most spoken language and meaningful cultural differences between English- and Spanish-speaking countries, the efficacy of EFT has not been examined in this cultural context. This study will examine the efficacy of EFT in this particular context and advance the understanding of potential mechanisms of change. Methods We will use a multicenter randomized wait-list controlled design to examine the efficacy of EFT in a Spanish-speaking sample of moderately distressed couples. One hundred forty individuals in 70 couples in Argentina, Costa Rica, Guatemala, Mexico, and Spain will be randomly assigned to receive 19-21 sessions of EFT or be placed on a waitlist. Outcomes on a range of relational and individual mental health variables will be assessed prior to random assignment, throughout treatment, and at the conclusion of treatment. Primary outcomes will include dyadic adjustment, couple satisfaction, and attachment. Secondary variables, such as loneliness, parenting, affective communication, and sexual satisfaction, will be included as potential mediators of the treatment effect. Couples in the treatment group will also be assessed at 3-, 6-, 12-, 18-, and 24-month follow-ups. Process variables such as the therapeutic alliance will also be assessed routinely in couples assigned to the treatment group. Couples in the waitlist will receive a psycho-educational program based on EFT after completing the study. Discussion This study will be the first RCT of Emotionally Focused Therapy in a Spanish-speaking context. The results of the study will inform researchers interested in whether treatments developed and tested in the USA and Canada can be effective in differing cultural contexts. It may also point researchers and clinicians to areas where cultural adaptation is needed to improve efficacy.

Aims To determine the associations between internal assets (planning and decision-making, interpersonal competence and commitment to learning) and substance use (tobacco, alcohol, binge drinking, marijuana use and other drugs). Design A cross-sectional study was conducted in four countries (Chile, Mexico, Spain and Peru). Methods Adolescents aged 12-18 self-completed a multi-purpose questionnaire between 2016 and 2019. Multiple logistic regressions and structural equation models were performed to analyse the association between internal assets (planning and decision-making, interpersonal competence, and commitment to learning) and substance use. Results The results indicate that planning and decision-making and commitment to learning are conducive to the prevention of substance use. On the contrary, interpersonal competence was not associated with substance use. Conclusion The present study shows that planning and decision-making and commitment to learning can be relevant factors in explaining substance use during adolescence. Internal assets can be an important aspect to include in health promotion interventions with children, youth and families to prevent substance use. These findings may be useful for researchers, schools, paediatric nurse practitioners, and health professionals in general to design health programs focused on children and adolescents. Furthermore, the Developmental Assets framework has been proved as a suitable frame of reference for paediatric nurse practitioners to assess and develop child and adolescent positive development and design health promotion interventions to prevent substance use.

Anonymous questionnaires are frequently used in research with adolescents in order to obtain sincere answers about sensitive topics. Most longitudinal studies include self-generated identification codes (SGICs) to match information. Typical elements include a combination of letters and digits from personal data. However, these data may make the participant feel that their answers are not truly anonymous, and some studies using these types of SGICs have been perceived as not entirely anonymous by some participants. Furthermore, data protection laws could place limits on research carried out with these codes. The objective of our article is to test an SGIC with a higher degree of anonymity. We conducted two studies. In Study 1, we tested the perceived anonymity of this new SGIC code. Adolescents aged 12 to 18 years (N = 601) completed an anonymous questionnaire about lifestyles and risk behaviors, which also included the SGIC. Adolescents with and without risk behaviors were compared regarding whether or not they answered to the SGIC questions. We did not find any differences to suggest that participants felt identifiable. In Study 2, we assessed the efficiency of the new SGIC. At baseline, 123 students from two high schools (eighth grade) filled in questionnaires consisting of the new SGIC and their full names. Two years later, these same students (then in the 10th grade) were invited to fill in the same information again (116 students responded to this second call). A total of 97 students were present in both waves. The SGIC showed a moderate performance, with good enough indices of recall and precision. Evidence suggests that the new SGIC is a suitable tool for the anonymous matching of adolescents in follow-ups of school cohorts.

This study tested an empirical model of the relationship between Personal Positive Youth Development (PPYD) and two contextual factors: Positive Parenting (PP), and Perception of the Climate and Functioning of the School (PcfS). The hypothesis tested was that a positive relationship with parents and a positive perception of the school will contribute to the prediction of PPYD. The sample was composed of 1507 adolescents recruited in 10 Spanish schools who were aged between 12 and 18 years and 52% were female. PPYD was evaluated through Dispositional optimism, Self-competence, and Sense of coherence. PP was evaluated through Affect and communication, Autonomy granting, Humor, and Self-disclosure. PcfS was evaluated through School climate, School bonds, Clarity of rules and values, and Empowerment. Previous reliability and validity analyses of the constructs were carried out, and correlational analyses and structural predictions were made. The results show that both PP and PcfS were associated with better scores in PPYD. Also, a positive correlation between those two contextual factors was found. Implications for applied research are discussed.

Este estudio presenta la validación del Differentiation of self Inventory for Adolescents de Knauth y Skowron (2004). La diferenciación del self, un concepto utilizado por la teoría familiar sistémica de Bowen, se define como la capacidad de autorregulación emocional e intimidad con los demás. Un total de 1987 participantes de entre 14 y 21 años de edad participaron en el estudio. Los resultados del AFE (muestra 1; n=546) no confirman la estructura de cuatro factores del instrumento original. Dos subescalas aparecen más claramente reflejadas (Reactividad emocional, RE, y Corte emocional, CE) en las agrupaciones de ítems. Considerando estos resultados junto con la teoría que sustenta el constructo, se utilizó la muestra 2, en el que buscamos evaluar, a través de un Análisis Factorial Confirmatorio (AFC; n=1441), el ajuste de una propuesta del S-DSI para adolescentes españoles compuesta por 2 subescalas (RE y CE), con 10 ítems en cada una de ellas. Los resultados apoyaron esta solución, que es coherente con la propuesta de validación de esta misma escala en su versión para adultos españoles (Rodríguez-González et al., 2015). Se discuten las limitaciones, implicaciones teóricas y futuras investigaciones.

Positive family functioning during adolescence is usually studied analyzing parents¿ competences and children¿s relationship abilities. We present an instrument for the assessment of parental competence, which encompasses both educational style and transmission of values. The objective of the study was to analyze its factor structure and to assess its value in predicting adolescent outcomes. We recruited 2,459 high school students, aged 12-15, in 40 schools from Spain, Peru, Mexico, and Chile. They responded to the instrument and to other questions regarding lifestyles. Exploratory and confirmatory factor analyses were carried out in order to assess the internal structure of the instrument, and internal consistency of the resulting dimensions was calculated. Finally, regression analyses were performed to establish associations between the parenting dimensions and adolescent outcomes. Factor analyses showed a consistent structure, with good fit indices in the four countries. The final four factors include parenting styles (Warmth and Demandingness) and education in values (Fortitude and Privacy). Regression analyses showed associations with adolescent outcomes. For example, adolescents¿ life satisfaction was best predicted by Warmth and Education in fortitude. Practical implications are suggested.

Background: Several instruments have been developed to assess adolescent dating violence but only few have been validated in Spanish-speaking settings. Some instruments are too long and may not be feasible to include them in a multipurpose questionnaire. We developed an instrument to be used in the YourLife project, an international project about young people lifestyles. Objective: We aimed to analyze the psychometric properties of this instrument in three Spanish-speaking countries (Chile, Ecuador, and Spain). Method: We included 1049 participants, aged 13-18 years. Exploratory and confirmatory factor analyses were conducted. Associations between dating violence and variables expected to covariate with it (substance use, school peer aggression, justification of dating violence, and relationship power imbalance), were tested. Results: Two different constructs (psychological and physical/sexual) for suffered and perpetrated violence were identified and confirmed in the three countries. The dating violence subscales had Cronbach's alpha scores higher than 0.85. The strongest associations between dating violence and variables related to it were found within the relationship power imbalance items, suggesting that these items may be useful to detect adolescent dating violence when a specific questionnaire cannot be implemented. Conclusion: This instrument seems to be adequate to assess suffered and perpetrated adolescent dating violence within a multipurpose questionnaire among schooled adolescents.

Oliva¿s Escala para la Evaluación del Estilo Parental (EEEP) [Scale for the evaluation of parenting styles] asks adolescents about their parents¿ education styles separately (¿your father¿ and ¿your mother¿) or in a combined way (¿your parents¿), but only the separated version has been tested for validity. The objective of this work was to carry out a validation of the combined version. A sample of 1507 adolescents, aged 12 to 18 years, was recruited. Exploratory and confirmatory factor analyses were run in two independent subsamples. Then, structural equation models (SEM) were run in order to test the association between the EEEP¿s subscales and adolescent outcomes (optimism, pessimism, and academic achievement). Results showed a good fit of the instruments¿ structure. Furthermore, the subscales showed associations with the outcomes. The EEEP can be reliably used in its combined form, which results in a reduction of items, often beneficial for research.
