Dietary inflammatory index of mothers during pregnancy and Attention Deficit-Hyperactivity Disorder symptoms in the child at preschool age: a prospective investigation in the INMA and RHEA cohorts.

Inflammation provides a substrate for mechanisms that underlie the association of maternal diet during pregnancy with Attention Deficit-Hyperactivity Disorder (ADHD) symptoms in childhood. However, no previous study has quantified the proinflammatory potential of maternal diet as a risk factor for ADHD. Thus, we evaluated the association of maternal dietary inflammatory index (DII®) scores during pregnancy with ADHD symptoms in 4-year-old children born in two Mediterranean regions. We analyzed data from two population-based birth cohort studies-INMA (Environment and Childhood) four subcohorts in Spain (N = 2097), and RHEA study in Crete (Greece) (N = 444). The DII score of maternal diet was calculated based on validated food frequency questionnaires completed during pregnancy (12th and/or 32nd week of gestation). ADHD symptoms were assessed by ADHD-DSM-IV in INMA cohort and by ADHDT test in RHEA cohort, with questionnaires filled-out by teachers and parents, respectively. The associations between maternal DII and ADHD symptoms were analysed using multivariable-adjusted zero-inflated negative binomial regression models in each cohort study separately. Meta-analysis was conducted to combine data across the cohorts for fitting within one model. The DII was significantly higher in RHEA (RHEA = 2.09 [1.94, 2.24]) in comparison to INMA subcohorts (Asturias = - 1.52 [- 1.67, - 1.38]; Gipuzkoa = - 1.48 [- 1.64, - 1.33]; Sabadell = - 0.95 [- 1.07, - 0.83]; Valencia = - 0.76 [- 0.90, - 0.62]). Statistically significant reduced risk of inattention symptomatology (OR = 0.86; CI 95% = 0.77-0.96), hyperactivity symptomatology (OR = 0.82; CI 95% = 0.72-0.92) and total ADHD symptomatology (OR = 0.82; CI 95% = - 0.72 to 0.93) were observed with increased maternal DII in boys. No statistically significant associations were observed in girls between maternal DII and inattention, hyperactivity and total ADHD symptomatology. We found reduced risk of ADHD symptomatology with increased DII only in boys. This relationship requires further exploration in other settings.

Evening salivary cortisol and alpha-amylase at 14months and neurodevelopment at 4years: Sex differences.

Stress system activity in early life can have long-term effects on neurodevelopment. The main aim of this study was to assess the association of child evening salivary cortisol and alpha-amylase basal levels at 14months of age with longer-term neuropsychological development at 4years in a low-risk population-based birth cohort derived from the INMA (Environment and Childhood) project in Spain. We included 186 parent-children pairs with information on both stress system activity and neurodevelopment. Both stress markers at 14months of age showed an association with neuropsychological development at 4years. Salivary cortisol showed a sex-specific pattern of association. In girls, cortisol levels at 14months were negatively associated with cognitive development [long-term declarative memory (ß=-17.8, p=0.028; 95% CI=-33.2 to -2.5); executive function (ß=-9.8, p=0.08; 95% CI=-21 to 1)] and gross motor development (ß=-13; p=0.022; 95% CI=-24 to -2), whereas in boys cortisol levels were negatively associated with socioemotional development [autistic-like behaviours: Incidence Rate Ratio (IRR)=1.6, p=0.039; 95% CI=1.01 to 2.41]. Salivary alpha-amylase was positively associated with socioemotional development in boys only [social competence (ß=2.11, p=0.013; 95% CI=0.47 to 3.72), autistic-like behaviours (IRR=0.93, p=0.042; 95% CI=0.87 to 0.99) and hyperactivity symptoms (IRR=0.81, p=0.021; 95% CI=0.69 to 0.97)]. These results suggest that stress system activity in early life is associated with longer-term neurodevelopment and that sex is an important factor in this relationship.

Reducing Anxiety and Improving Academic Performance Through a Biofeedback Relaxation Training Program.

The aim of this study was to analyze the influence of a biofeedback relaxation training program on anxiety and academic performance. The program consisted of five biofeedback sessions coupled with three training activities focused on deep breathing, guided imagery, and muscle relaxation. The participants were second-year psychology undergraduates from the University of the Basque Country (UPV/EHU, northern Spain). The experimental group comprised 152 students (M age = 19.6, SD = 0.74; 74% women) and the control group 81 students (M age = 19.4, SD = 0.92; 71% women). Results showed that after participating in the program, students in the experimental group had lower levels of anxiety and increased academic performance. Furthermore, they scored lower on anxiety and higher on academic performance in comparison with the control subjects. This suggests that the inclusion of biofeedback training programs in educational contexts could be a way of reducing anxiety and improving academic performance. It may also deepen our understanding of the dynamic interplay between psychophysiological, cognitive, and emotional processes.

Animal-assisted psychotherapy for young people with behavioural problems in residential care.

The aim of this study was to evaluate the impact of an animal-assisted psychotherapy (AAP) programme on clinical symptoms, personal adjustment, and adaptive skills in a group of adolescents in residential care who had experienced childhood trauma and who presented mental health problems and difficulties adapting to the care home environment. The 87 participants (Mage  = 15.17, SD = 1.53) were divided into two groups: a treatment group (25 girls and 27 boys; Mage  = 15.00, SD = 1.55) and a control group (9 girls and 26 boys; Mage  = 15.42, SD = 1.50). The programme consisted of 34 sessions involving both group (23 sessions) and individual (11 sessions) AAP. The Behaviour Assessment System for Children was used to evaluate clinical and adaptive dimensions of behaviour and personality. The results indicated that, in comparison with controls, the young people who took part in the AAP programme reported a significant improvement on two measures of internalizing symptoms, namely, depression and sense of inadequacy. Although no significant differences were observed in relation to externalizing symptoms, the adolescents who received the AAP programme showed improved social skills in terms of their ability to interact satisfactorily with peers and adults in the care home environment, as well as a more positive attitude towards teachers at school. These results suggest that AAP may be a promising treatment for young people who have experienced childhood trauma and who subsequently find it difficult to adapt to the residential care setting.

Peer attachment and class emotional intelligence as predictors of adolescents' psychological well-being: A multilevel approach.

The aim of the study was to analyze whether gender, age, peer attachment, and class-level emotional intelligence could predict adolescents' psychological well-being by applying a multilevel approach. The sample comprised 2182 secondary school students from the Basque Country (northern Spain) (from 118 classrooms, 51.6% girls), aged between 12 and 18 years. A two-level model (with students nested into classes) was used to analyze the influence of three level-one covariates (gender, age, and peer attachment) and one level-two covariate (class-level emotional intelligence) on the positive affect component of psychological well-being. The results showed an overall decrease in well-being as adolescents grow older, and an increase linked to a higher peer attachment. Furthermore, class-level emotional intelligence showed a positive relationship with students' well-being. This group-level covariate also strengthened the effect of peer attachment on the well-being. The advantages of using a multilevel approach for predicting mental health and psychological adjustment are discussed.

Cross-cultural adaptation and psychometric validation of a Spanish version of the Maryland Assessment of Recovery Scale (MARS-12).

The aim of this study was to adapt and validate a Spanish version of the Maryland Assessment of Recovery Scale (MARS-12). It was carried out in strict accordance with internationally recognized guidelines for test adaptation. A preliminary Spanish version of the MARS-12 was first produced through a standardized translation/back-translation process, ensuring semantic, linguistic, and contextual equivalence with respect to the original scale. Its psychometric properties were then examined in a sample of 325 people with serious mental illness recruited from six different provinces in the Basque Country (northern Spain) and Catalonia (north-eastern Spain). They were users of a total of 20 community rehabilitation and psychiatry services. Confirmatory factor analysis supported a unidimensional structure, consistent with the original scale. Scores on the MARS-12 were positively correlated (.83) with scores on the Questionnaire about the Process of Recovery, supporting convergent validity, while validity evidence based on relationships with other variables was provided by positive correlations between MARS-12 scores and scores on the Dispositional Hope Scale (.82) and on the three dimensions of the Multidimensional Scale of Perceived Social Support (range .30 to .41). Reliability of MARS-12 scores was high (McDonald's ω = .97), as was temporal stability across a one-week interval (.89). The Spanish version of the MARS-12 is a valid and reliable scale that may be used by mental health professionals to assess recovery among Spanish people with serious mental illness.

Psychometric Properties and Factorial Invariance of the Educational-Clinical Questionnaire: Anxiety and Depression (CECAD) in Basque Population.

BACKGROUND: Anxiety and depression are the most common current mental health problems. Due to their comorbidity, there is a need for instruments that measure them simultaneously. Moreover, given that their prevalence varies by gender and age, it is important to examine the factorial invariance of such instruments. The present study aimed to analyze the dimensionality and factorial invariance of the Basque version of the Educational-Clinical Questionnaire: Anxiety and Depression (CECAD) as a function of gender and age, and to gather additional evidence of its validity. METHOD: The sample comprised 2131 participants (54.2% female) between 7 and 24 years old ( M = 13.2; SD = 3.52). RESULTS: The CECAD was found to have a two-dimensional structure invariant to gender and age, with higher latent means for girls in both dimensions, and for those aged 14 and over in depression, but with small effect sizes. Both reliability and convergent validity values were good. CONCLUSIONS: The Basque version of the CECAD has good evidence of validity and reliability for assessing anxiety and depression in Basque-speaking children and adolescents.

Our lifestyles are back to 'normal', but is our mental health? Longitudinal assessment of psychological distress during the COVID-19 pandemic among Spanish adults: April 2021 to August 2022.

The COVID-19 pandemic had a detrimental effect on mental health since its start in 2020 and current data on mental health is limited. This study provides recent longitudinal data on psychological distress among a country-wide sample of adults. We recruited and surveyed 1,956 adults in Spain in April 2021 and August 2022 on sociodemographic- and pandemic-related psychological distress using the General Distress 21-item version of the Depression, Anxiety, and Stress Scale (DASS). Paired sampled t-tests assessed DASS scores by sex from April 2021 to August 2022; and one-way ANOVAs assessed DASS scores across sociodemographic characteristics. Results showed that psychological distress slightly improved across the total sample from April 2021 to August 2022; though females, young adults, students, and individuals with lower income experienced more psychological distress. Increases in severe stress scores were found particularly among men. Our data provides an overview of the psychological distress of Spanish adults 2.5 years into the pandemic and provides novel evidence that though life has resumed a sense of normalcy after the COVID-19 pandemic, the mental health of key populations (e.g., females, young adults, students, low-income) is still suffering and further intervention and resources are needed.

Effects of an emotional intelligence intervention on aggression and empathy among adolescents.

The aim of this study was to explore the effects of a two-year intervention grounded in the ability model of emotional intelligence (EI) on aggression and empathy among adolescents. Eight Spanish public schools volunteered to participate in the research. A total of 590 adolescents (46% boys) were randomly assigned to either the EI training group or control group conditions. Students in the EI training group reported lower levels of physical/verbal aggression, anger, hostility, personal distress and fantasy compared to students in the control group. Additionally, the EI program was particularly effective for males' empathic abilities. These findings confirm the effectiveness of social and emotional learning interventions in Spanish academic contexts and extend the literature of gender-related differences during adolescence. Study limitations and future research directions are also considered.

Assessment of Attachment Representations in Basque Adolescents and their Relationship with Internalizing and Externalizing Problems.

Research has shown a relationship between attachment style and psychosocial adjustment in adolescents. Whereas secure attachment is related to fewer internalizing and externalizing symptoms, the opposite is the case for the various insecure attachment styles. The aim of the two studies reported in this paper was to adapt and validate the CaMir-R (a self-report measure of attachment that has shown adequate psychometric properties) for use among Basque adolescents, and to analyse the relationship between attachment and internalizing and externalizing symptoms. In Study 1, the instrument was adapted using the back translation method and applied to a sample of 203 adolescents and young adults. Confirmatory factor analysis supported the theoretical dimensions of the scale, and its psychometric properties were found to be adequate. In Study 2 we obtained additional validity evidence by applying, in a sample of 786 adolescents and young adults, the attachment representations section of the CaMir-R alongside other measures of attachment and clinical symptoms. The results once again supported the dimensional structure of the instrument, and evidence of convergent validity was obtained based on correlations between CaMir-R scores and scores on the Inventory of Parent and Peer Attachment (IPPA). In addition, scores on the five dimensions of attachment representations (Security, Family concerns, Parental interference, Self-sufficiency and resentment of parents and Childhood trauma) were correlated with scores on other measures of internalizing and externalizing symptoms. Based on these results, we conclude that the Basque version of the CaMir-R is a valid instrument for assessing the quality of attachment representations among adolescents, and also that internalizing and externalizing problems are related to attachment style. We discuss the importance of attachment in relation to behaviour problems and clinical symptoms.

Neuropsychological features of asymptomatic c.709-1G>A progranulin mutation carriers.

Mutations in the progranulin (PGRN) gene have been identified as a cause of frontotemporal dementia (FTD). However, little is known about the neuropsychological abilities of asymptomatic carriers of these mutations. The aim of the study was to assess cognitive functioning in asymptomatic c.709-1G>A PGRN mutation carriers. We hypothesized that poorer neuropsychological performance could be present before the development of clinically significant FTD symptoms. Thirty-two asymptomatic first-degree relatives of FTD patients carrying the c.709-1G>A mutation served as study participants, including 13 PGRN mutation carriers (A-PGRN+) and 19 non-carriers (PGRN-). A neuropsychological battery was administered. We found that the A-PGRN+ participants obtained significantly poorer scores than PGRN- individuals on tests of attention (Trail-Making Test Part A), mental flexibility (Trail-Making Test Part B), and language (Boston Naming Test). Poorer performance on these tests in asymptomatic PGRN mutation carriers may reflect a prodromal phase preceding the onset of clinically significant symptoms of FTD.

Validation of Children's Depression Scale in the Basque-speaking population.

The aim of this study was to validate the Basque version of the CDS (Children's Depression Scale, Lang & Tisher, 1978), one of the most widely used questionnaires for the assessment of childhood depression, which has already been proved to be a valid and reliable tool in different cultures. The questionnaire was administered to a community sample of 886 participants (432 males and 454 females) aged between 8 and 16. A two-factor solution was obtained (Depressive dimension and Positive Dimension), which accounted for 29.86 % of the variance. Reliability with regard to internal consistency level and long-term stability was good (alpha = .95 and .79; and R = .73 and .59 for Depressive and Positive dimensions, respectively). Analysis of Differential Item Functioning with respect to age and gender showed that 91% and 88% of the items, respectively, did not present DIF. External validity evidence for the questionnaire was also obtained. We consider that the present work offers researchers and professionals interested in this area of study a valid and reliable tool for assessing depressive symptoms in Basque-speaking children and adolescents.

Assessment of Adaptive Performance and its Role as a Moderator of the Relationship Between Person-Organization Fit and Organizational Citizenship Behaviors.

BACKGROUND: Adaptive performance is of central interest for today's organizations, insofar as employees increasingly need to be able to adjust their behaviors to dynamic, changing work situations. The aims of this study were to develop a Spanish adaptation of Charbonnier-Voirin and Roussel's (2012) scale for measuring adaptive performance, and to examine whether the dimensions of adaptive performance moderate the relationship between person-organization fit (PO fit) and organizational citizenship behaviors (OCBs). We hypothesized that the relationship between PO fit and OCBs would be stronger in individuals with a higher level of adaptive performance. METHOD: The sample comprised 678 employees (65% women) in the public sector in the Basque Country. They ranged from 21 to 63 years old (M = 44.63; SD = 7.66). RESULTS: The Spanish version of the scale has good psychometric properties. Furthermore, the Interpersonal Adaptability dimension of adaptive performance moderates the relationship between PO fit and OCBs directed both at the organization and at individuals, following the expected direction. The relationship between PO fit and OCBs directed at individuals was also moderated by the Reactivity in the Face of Emergencies dimension. CONCLUSIONS: We discuss the practical implications of these results in the field of personnel selection.

Is Social Media a New Type of Social Support? Social Media Use in Spain during the COVID-19 Pandemic: A Mixed Methods Study.

This study examines Spanish adults' social media use during the COVID-19 pandemic using mixed-methods to assess and understand frequency, context, and changes in social media use during two critical time points in Spain. We conducted semi-structured interviews in April 2020, and two waves of surveys (April 2020, April 2021) among Spanish adults. We coded and analyzed qualitative data related to social media use during the first lockdown period in Spain using Dedoose software; and ran descriptive statistics and chi-square tests to assess changes in social media use over the two survey waves related to perceived social support and loneliness. Participants ranged in age from 18-92 and were representative of the Spanish population's sociodemographics. Interview data show that WhatsApp was most commonly used, and that social media allowed for social support and engaging in healthy behaviors. Survey data show that women and individuals aged 18-34 had the greatest increases in social media use. Statistically significant associations were found between social support and loneliness with social media use. Our results show that promoting social media use as an emotional resource for social support in times of crisis or isolation can minimize loneliness and can be a beneficial tool for general worldwide crises.

Promoting adherence to psychopharmacological treatment among prisoners with mental health problems: Follow-up of a randomized controlled trial.

This study presents follow-up results regarding a treatment adherence programme (TAP) for prisoners, the initial effectiveness of which we previously evaluated in a randomized controlled trial. Here we used an experimental design with two randomized groups and assessment at four time points: baseline (pre-intervention), at 3 months (post-intervention), and at 6 and 9 months after baseline. Participants were 151 prisoners with mental health problems (Mage = 41.85, SD = 10.31) who were randomly assigned to either the TAP or treatment as usual (TAU). Prisoners who completed the TAP showed a greater improvement in treatment adherence at 3 and 9 months, compared with those who received TAU. There were no significant differences between the groups in subjective well-being under medication. The availability of an easy-to-apply, universal programme that is able to promote treatment adherence in the prison context could make a positive contribution to the general health of inmates.

Assessment of Personality in Basque Public Sector Employees and Its Role in Predicting Organizational Citizenship Behaviors in Selection Processes.

Organizational citizenship behaviors (OCBs) are an important aspect of job performance as they enhance the effectiveness of organizations. Research has shown that personality is a moderate predictor of job performance. This study, involving a sample of 678 public sector employees in the Basque Country (northern Spain), pursued two aims: First, to develop and validate a Basque-language version of the Overall Personality Assessment Scale (OPERAS), a scale designed to assess the Big Five personality factors in a wide range of settings; and second, to examine whether person-organization fit (PO fit) and adaptive performance improve the capacity of personality to predict OCBs. The results indicated that the adapted scale was a suitable instrument for assessing personality in the Basque-speaking population. Furthermore, PO fit and adaptive performance improved the capacity of personality to predict OCBs. Based on these results, we propose a new predictive model that may enhance the efficiency of personnel selection processes.

A Social-Emotional Learning Program for Suicide Prevention through Animal-Assisted Intervention.

The aim of the study was to carry out a pilot implementation and evaluation of the OverCome-AAI program, a pioneering program for the prevention of suicidal behavior through animal-assisted interventions for young people with high risk factors for suicidal behavior. The study sample consisted of 30 adolescents (11 boys and 19 girls) aged between 14 and 17 years (Mean age = 15.50, SD = 1.60) from the Basque Country (Northern Spain). After the intervention, subjects presented reductions in suicidal ideation, suicide plans, and non-suicidal self-harm, as well as a greater predisposition to seek help. A reduction in the intensity of mental pain was also found, although no differences were observed in indicators of hopelessness and depression. The preliminary results obtained in this pilot study suggest that the OverCome-AAI program may be effective in reducing suicidal behavior and non-suicidal self-harm in young people in residential care who present high risk factors for suicide.

General linear mixed model for analysing longitudinal data in developmental research.

Many areas of psychological, social, and health research are characterised by hierarchically structured data. Growth curves are usually represented by means of a two-level hierarchical structure in which observations are the first-level units nested within subjects, the second-level units. With data such as these, the best option for analysis is the general linear mixed model, which can be used even with longitudinal data series in which intervals are not constant or for which over the passage of time there is loss of data. In this paper an overview is given of the general linear mixed model approach to the analysis of longitudinal data in developmental research. The advantages of this model in comparison with the traditional approaches for analysing longitudinal data are shown, emphasising the usefulness of modelling the covariance structure properly to achieve a precise estimation of the parameters of the model.

Multilevel approach to stressors, coping, and psychopathological symptoms.

A 4-yr. longitudinal study was conducted of the relationship between stressors, coping strategies, and psychopathological symptoms in a group of 447 adolescents. The Coping Responses Inventory-Youth Form and the Youth Self-Report were used to evaluate coping strategies and psychopathological symptoms, respectively. Stressors were identified on the basis of written reports produced by the adolescents and coded using the System of Coding Problems of Adolescents. A multilevel approach showed that scores for externalizing symptoms increased significantly with age. General distress and internalization also tended to increase with age, although without reaching statistical significance. Approach and avoidance coping strategies remain stable across the ages studied. Avoidant coping increases psychopathological symptoms, whereas the influence of approach coping depends on the type of stressor (personal, interpersonal, or nonpersonal).

Use of multilevel logistic regression to identify the causes of differential item functioning.

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups.
