The present study is centered in adapting and validating a Spanish version of the Irrational Procrastination Scale (IPS). The sample consists of 365 adults aged 18-77 years (M = 37.70, SD = 12.64). Participants were administered two measures of procrastination, the IPS and the Decisional Procrastination Questionnaire, as well as the Big Five Inventory, and the Satisfaction With Life Scale. First, the factor and replication analysis revealed that the internal structure of the scale is clearly one-dimensional, supporting the idea that IPS seems to measure general procrastination as a single trait. Second, the internal consistency is satisfactory as is the temporal stability of the IPS scores. Third, the correlations encountered between the IPS scores and other measures of procrastination, personality traits and satisfaction with life are all in the expected direction and magnitude. Finally, consistent with previous research, procrastination is related to age, with the youngest being the most procrastinating group. This study represents the first attempt in adapting and validating the IPS measure of procrastination into Spanish. Results suggest that the Spanish version of the IPS offers valid and reliable scores when applied to adult population.

Schizophrenia is a severe mental disorder associated with impairment in functioning. A multidisciplinary approach is essential to help individuals with this health condition, and psychological interventions are considered a priority. The International Classification of Functioning, Disability and Health (ICF) offers a theoretical framework for assessing functioning and disability. The ICF Core Sets for schizophrenia are a list of ICF categories describing the most common problems in functioning of persons affected by this health condition. This study aimed to explore the content validity of these ICF Core Sets and to identify the most common problems in people with schizophrenia from the perspective of psychologists. Psychologists with experience of schizophrenia treatment were recruited for a three-round Delphi study in order to gather their views regarding the problems commonly presented by these patients. A total of 175 psychologists from 46 countries covering the six WHO regions answered the first-round questionnaire, and 137 completed all three rounds. The 7,526 concepts extracted from first-round responses were linked to 412 ICF categories and 53 personal factors. Consensus (≥75% agreement) was reached for 76 ICF categories and 28 personal factors. Seventy-three of the 97 ICF categories that form the Comprehensive ICF Core Set for schizophrenia achieved consensus, and only three categories that yielded consensus do not feature in this Core Set. These results support the content validity of these ICF Core Sets from the perspective of psychologists. This provides further evidence of the suitability of the ICF framework for describing functioning and disability in persons with schizophrenia.

The Brief Self-Control Scale (BSCS) is a 13-item personality measure capturing how people differ in their capacity to exert self-control. Although the BSCS was originally regarded as a one-dimensional scale, subsequent psychometric studies have provided support for the empirical distinction of two and four interrelated but distinct components of self-control. Using a large sample of Spanish adults ( n = 1,558; 914 female, 58.7%), we performed a comprehensive data-driven comparison of the most well-established item-level latent structures for the BSCS. Results showed that the differentiation between general self-discipline and impulse control offered a better fit to the observed data than did the unidimensional representation of self-control. This two-dimensional structure for the BSCS scores was also supported in terms of its internal consistency, measurement invariance across gender and age groups, and meaningful correlations with wellbeing-related indicators and Big Five personality traits. Plausible implications of these findings are discussed.

This study focuses on the adaptation and psychometric validation of the Spanish versions of the Agentic Engagement Scale (AES) and the Enlarged Version of the Agentic Engagement Scale (EVAES) in Spanish undergraduate students. Agentic engagement, denoting the educational insights provided by students during classroom instruction, has garnered attention for its potential impact on teaching and learning. Reeve initially developed the AES in 2013, which Mameli and Passini extended from 5 to 10 items in 2019 to create the EVAES. In a sample of 278 undergraduate students, this study thoroughly examined various psychometric properties, including item response distribution, factor structure, internal consistency, test–retest reliability, and validity evidence. The results consistently demonstrated high item-total correlations, a one-factor structure, good internal consistency, and satisfactory test–retest reliability for both scales. Additionally, the study established validity evidence through positive and significant correlations between agentic engagement and academic engagement, as well as with personality traits such as extraversion, agreeableness, conscientiousness, emotional stability, and openness to experience. In conclusion, the Spanish versions of the AES and EVAES emerge as promising tools for assessing agentic engagement among Spanish-speaking undergraduate students, offering valuable insights into their active participation and contributions to the instructional process.

Objectives To develop and validate a Spanish version of the Athens Insomnia Scale (AIS). Methods The AIS is designed to assess sleep difficulty and comprises eight items: the first five refer to the sleep disturbance and the last three to the daytime consequences. Either the full eight-item scale (AIS-8) or the brief form (AIS-5) can be administered. The adaptation used a backtranslation design. The validation process was based on a sample of 323 participants (undergraduates, community sample and psychiatric outpatients), which completed the AIS and other questionnaires anxiety (BAI), depression (BDI) and psychological well-being (GHQ-12) scales. Results The internal consistency coefficients for both versions were above 0.80. The study of dimensionality revealed a single factor with high loadings and a percentage of explained variance above 50% in both versions. Test-retest reliability was above 0.70 (AIS-5) and over 0.80 (AIS-8) at a one-month interval. The correlation between the AIS and the previously mentioned scales was for both the AIS-5 and the AIS-8 above 0.40 and 0.50, respectively. Conclusion The psychometric properties of both versions of the Spanish form of the AIS demonstrate that the scale is a valid and reliable instrument for the assessment of insomnia in Spanish-speaking populations.

Establishing the evidence base of interventions taking place in areas such as psychology and special education is one of the research aims of single-case designs, in conjunction with the aim of improving the well-being of participants in the studies. The scientific criteria for solid evidence focus on the internal and external validity of the studies, and for both types of validity, replicating studies and integrating the results of these replications (i.e., meta-analyzing) is crucial. In the present study, we deal with one of the aspects of meta-analysis—namely, the weighting strategy used when computing an average effect size across studies. Several weighting strategies suggested for single-case designs are discussed and compared in the context of both simulated and real-life data. The results indicated that there are no major differences between the strategies, and thus, we consider that it is important to choose weights with a sound statistical and methodological basis, while scientific parsimony is another relevant criterion. More empirical research and conceptual discussion are warranted regarding the optimal weighting strategy in single-case designs, alongside investigation of the optimal effect size measure in these types of designs.

Background Many countries today are undergoing a paradigm shift in mental health policies towards a recovery-oriented and rights-based approach. From this perspective, self-determination and self-management are fundamental factors for recovery. Despite this shift, there is still a lack of evidence on the effectiveness of training programmes aimed at promoting self-determination and self-management in recovery processes implemented in southern European or Spanish-speaking countries. The aim of this paper is to present a study protocol that evaluates the effectiveness of a 12-session recovery workshop implemented in community mental health services in Catalonia (Spain). Methods/design This is a 12-week follow-up multi-centre non-randomized controlled trial design. At least 160 users will be recruited from 13 Community Rehabilitation Services (CRS) in Catalonia. Eligible participants are adult (≥ 18 years old) users of a CRS, who sign a written consent to participate. The experimental group participates in a recovery workshop, in which people learn to develop and implement their own plan of personal recovery, which includes a Wellness Toolbox, a Maintenance Toolkit, a Personal Growth Plan, a Mirror of Relapses, a Crisis Plan, and a Learning Agenda. The control group participates in the usual activities of the CRS. Data is collected using a questionnaire of sociodemographic characteristics, personal recovery, empowerment, hope and perceived social support. The users’ measurements are taken at the baseline and one week after the end of the workshop. The primary outcome measures include the Self-Identified Stage of Recovery and the Maryland Assessment of Recovery in Serious Mental Illness Scale (short version). The secondary outcome measures include the Netherlands Empowerment List, Dispositional Hope Scale, and Multidimensional Scale of Perceived Social Support. Descriptive statistics for characterizing the sample size will be performed. Multivariate analyses for repeated measures designs will be used to evaluate the primary and secondary outcomes. Between-group and within-subject comparisons will be conducted. Discussion The results of the study will provide information on the usefulness of recovery workshops in a Mediterranean cultural context. Additionally, if this workshop is effective, it will be proposed for inclusion within the portfolio of community mental health services in Catalonia.

The purpose of this study is to describe how a mixed methods approach was used to gain a better understanding of functioning in schizophrenia. A two-phase design was employed. In the first phase, four independent qualitative and quantitative preparatory studies were concurrently carried out to identify areas of convergence. In the second phase, we held a consensus conference with an international panel of experts to explore how these preparatory studies contributed to the final list of areas of functioning in schizophrenia. The data of the preparatory studies were complementary, and the qualitative methodology (i.e., focus groups with patients and families) was the main contributor to the final list. The experience of the conference of experts highlights the importance of the consensus process for capturing a range of cultural differences.

The comprehensive and brief International Classification of Functioning, Disability and Health (ICF) core sets for schizophrenia, based on the World Health Organization (WHO) framework, aim to describe the functioning of individuals with schizophrenia. The objective of this study was to identify the most common problems faced by these individuals and validate the ICF core sets. Eight focus groups were conducted, recorded, and transcribed verbatim. The linking process involved two independent coders identifying meaningful units and linking agreed-upon concepts to the ICF categories. Data saturation was defined as the point at which no new categories emerged from additional focus groups. The 37 participants in this study represented the WHO regions of Africa, South-East Asia, the Western Pacific, and Europe. The focus groups confirmed the relevance of all ICF core set categories, with an additional 21 second-level categories being proposed in at least six of the eight focus groups. In this study, the ICF core sets for schizophrenia were validated from the perspective of individuals. However, several second-level categories not currently included in the ICF core sets also emerged. To ensure that the ICF core sets are truly international in scope, the potential relevance of these categories should be investigated further.

Background The concept and assessment of resilience have attracted considerable attention in recent years, but none of the instruments developed to measure resilience in adolescents have been adapted to the Spanish context. The Adolescent Resilience Questionnaire (ARQ) provides a comprehensive and multidimensional assessment of the resources associated with resilience in adolescents. Methods This study analyzes the psychometric properties of the ARQ. Participants included a community sample of 1101 Spanish adolescents (53.5 % boys) aged 12–17 years ( M  = 14.51; SD  = 1.755). Results Results confirm the factor structure based on 12 scales. Internal consistency was generally adequate (between .60 and .84), although the unacceptable coefficient for the Empathy/Tolerance scale (α = .38) means that this scale needs to be revised for the Spanish context. Relationships between ARQ scales and psychopathology were in the expected direction and magnitude. Some gender differences were observed, with higher scores for boys on Confidence and Negative cognition . Conclusions The Spanish version of the ARQ can help to identify personal characteristics associated with resilience and signs of positive engagement with family, peers, school, and the community. It can identify those adolescents most likely to show resilience in response to adversity, as well as those who may be vulnerable under situations of stress.
