RESUMEN

The field of developmental psychopathology tends to focus on the negative aspects of functioning. However, prosocial behavior and empathy-related responding - positive aspects of functioning- might relate to some aspects of psychopathology in meaningful ways. In this article, we review research on the relations of three types of developmental psychopathology- externalizing problems (EPs), internalizing problems (IPs), and Autism Spectrum Disorder (ASD) - to empathy-related responding (e.g., affective and cognitive empathy, sympathy, personal distress) and prosocial behavior. Empathy-related responding and prosocial behavior generally have been inversely related to EPs, although findings are sometimes reversed for young children and, for empathy, weak for reactive aggression. Some research indicates that children's empathy (often measured as emotional contagion) and personal distress are positively related to IPs, suggesting that strong sensitivity to others' emotions is harmful to some children. In contrast, prosocial behaviors are more consistently negatively related to IPs, although findings likely vary depending on the motivation for prosocial behavior and the recipient. Children with ASD are capable of prosocially and empathy-related responding, although parents report somewhat lower levels of these characteristics for ASD children compared to neurotypical peers. Issues in regard to measurement, motivation for prosociality, causal relations, and moderating and mediating factors are discussed.

RESUMEN

INTRODUCTION: Existing research highlights the significance of prosocial behavior (voluntary, intentional behavior that results in benefits for another) to people's well-being. Yet, the extent to which this expected positive relation operates at the within-person level (e.g., is more prosocial behavior than usual related to a higher than usual level of well-being?) while taking into account stable interindividual differences, remains a research question that deserves further investigation. In this study, we aimed to explore the relations between prosocial behavior and hedonic (HWB; subjective assessment of life satisfaction and happiness) and eudaimonic (EWB; actualization of human potential in alignment with personal goals, including concepts like meaning in life and closeness to others) well-being in daily life. METHOD: Using ecological momentary assessment for 4 weeks, data were collected from two British samples, comprising 82 adolescents and 166 adults. RESULTS: Dynamic Structural Equation Modeling revealed a positive relations between prosocial behavior and HWB/EWB at both between and within-person levels across the samples. CONCLUSION: In summary, these findings further support the positive link between prosocial behavior and well-being in everyday life. Notably, this association was consistent across different age groups (adolescent and adults) at both between and within-person levels.

RESUMEN

The dynamic interplay of parental educational aspirations and children's academic self-concept was examined from late childhood through mid-adolescence within a transactional socialization framework. Parental and child data were gained from a representative Swiss sample within 3-year intervals (NT1  = 1118; 51% females; 28% migration background; Mage T1  = 9.26, Mage T2  = 12.14, Mage T3  = 15.32). Results from a random intercept cross-lagged panel model revealed positive associations between the two constructs at the between- and within-person level. Findings showed general and time-specific associations between children and parents and reciprocal spill-over effects, whereby higher than usual aspirations predicted higher than usual academic self-concept over time and vice versa, highlighting transactional processes in the context of educational transitions.

RESUMEN

The transition to motherhood triggers changes in human brain structure that may facilitate mother-infant bonding. Although much research on maternal cortical responses to infant faces has focused on the postpartum period, no previous study has examined whether longitudinal functional changes in the maternal cortex during pregnancy and postpartum are associated with mother-infant bonding. Using electroencephalography, prenatal to postnatal changes in cortical sensitivity (P1, P2, late positive potential, N170 event-related potentials) to infant and adult faces were examined in relation to reported mother-infant bonding in 40 mothers (Mage  = 30.5 years). Prenatal to postnatal increases in P1 and P2 responses to infant faces predicted stronger bonding. Findings suggest that cortical changes in attention allocation rather than in face-specific encoding enhance bonding.

RESUMEN

The purpose of this study was to evaluate the role of prosocial behaviour against aggression in a school-based universal intervention adapted in two different (non-Western) countries, Colombia and Chile. Using a randomised pretest-post-test design (and controlling for participants' gender and parents' level of education), current results highlighted different effects of a similar programme in both sites. First, the school-based universal programme designed for promoting prosocial behaviours in the peer context obtained a positive cross-national effect on prosocial behaviour rated by three informants (i.e. self, peer and teacher reports). In Colombia, this effect was moderated by the initial level of prosociality of the participants and their level of education. Mediational two-wave model corroborated that the improvement on prosocial behaviours in both countries (moderated in the case of Colombia) predicted significantly lower level of physical aggression. Characteristics of the implementation considering different cultural and historical backgrounds were discussed.

RESUMEN

To understand the conditions fostering positive outcomes of inclusive schooling, this two-wave study examined the role of individual change in trust and sympathy for adolescents' cross-group friendships and inclusive attitudes toward students with low academic achievement. Cross-group friendships, intergroup trust, intergroup sympathy, and inclusive attitudes were obtained from surveys completed by 1,122 Swiss adolescents (Mage T1  = 11.54 years, Mage T2  = 12.58 years) from 61 school classes. Results from a parallel latent change score model revealed that the number of cross-group friendships positively related to individual change in trust and sympathy; this growing trust and sympathy in turn predicted adolescents' inclusive attitudes. These findings are discussed regarding theories of intergroup contact and inclusive schooling.

RESUMEN

OBJECTIVE: Researchers have demonstrated the prediction of academic functioning by children's prosocial behavior (PB). The goal of our study was to examine the contribution of adolescents' PB for middle and senior high school grades after controlling for stability of achievement and for intelligence, Big Five traits, and sociodemographic variables (i.e., sex and socioeconomic status). METHOD: Study 1 examined on 165 adolescents (48.5% boys) the prediction by peer-reported PB in 7th grade of academic achievement at the end of junior high school, after controlling for the above variables. Study 2 examined the prediction by 927 (52% girls) 8th graders' PB of academic achievement 5 years later, at the end of senior high school, taking into account the stability of grades, personality traits, and socio-structural variables. RESULTS: Overall, hierarchical regression analysis indicated in both studies PB and Openness significantly predicted better grades in the short term and over time despite the high stability of grades across 5 years. Extraversion negatively predicted academic achievement across 1 year in junior high school. CONCLUSION: Findings supported the view of PB as a strength and a key resource for adolescents' academic attainment.

RESUMEN

Knowing every child's social-emotional development is important as it can support prevention and intervention approaches to meet the developmental needs and strengths of children. Here, we discuss the role of social-emotional assessment tools in planning, implementing, and evaluating preventative strategies to promote mental health in all children and adolescents. We, first, selectively review existing tools and identify current gaps in the measurement literature. Next, we introduce the Holistic Student Assessment (HSA), a tool that is based in our social-emotional developmental theory, The Clover Model, and designed to measure social-emotional development in children and adolescents. Using a sample of 5946 students (51% boys, M age = 13.16 years), we provide evidence for the psychometric validity of the self-report version of the HSA. First, we document the theoretically expected 7-dimension factor structure in a calibration sub-sample (n = 984) and cross-validate its structure in a validation sub-sample (n = 4962). Next, we show measurement invariance across development, i.e., late childhood (9- to 11-year-olds), early adolescence (12- to 14-year-olds), and middle adolescence (15- to 18-year-olds), and evidence for the HSA's construct validity in each age group. The findings support the robustness of the factor structure and confirm its developmental sensitivity. Structural equation modeling validity analysis in a multiple-group framework indicates that the HSA is associated with mental health in expected directions across ages. Overall, these findings show the psychometric properties of the tool, and we discuss how social-emotional tools such as the HSA can guide future research and inform large-scale dissemination of preventive strategies.

RESUMEN

Family socio-economic status (SES) represents one of the major determinants of youth's scholastic achievement, and thus it is important to unravel the psychological factors underlining this relation. In this article, we examined youth's ability to flexibly adapt and, thus, cope with harsh environmental conditions-assessed by the construct of ego-resiliency-as a mediating mechanism in the across-time association between family SES and academic achievement. The longitudinal sample was composed of 265 (56% females) Italian students who were about 13 years old at Time 1 (T1) and about 18 years old at Time 2 (T2). In a structural equation model analysis, family SES significantly predicted ego-resiliency 6 years later while controlling for the latter's strong longitudinal stability. Students' school grades at the end of senior high school were also predicted by ego-resiliency assessed at the age of 13, controlling for grades in the last year of junior high school, gender, and initial differences in ages. In accordance with the posited hypothesis, this study provided support for a two-wave meditational model in which the relation between family SES at 13 years and later school grades at 19 years was mediated by ego-resiliency. All in all, results support the argument that being resilient, and thus being able to flexibly adapt one's own emotional state and resultant behavior, matters to school success.

RESUMEN

This study examined the role of sympathy, guilt, and moral reasoning in helping, cooperation, and sharing in a 6-year, three-wave longitudinal study involving 175 children (Mage 6.10, 9.18, and 12.18 years). Primary caregivers reported on children's helping and cooperation; sharing was assessed behaviorally. Child sympathy was assessed by self- and teacher reports, and self-attributed feelings of guilt-sadness and moral reasoning were assessed by children's responses to transgression vignettes. Sympathy predicted helping, cooperation, and sharing. Guilt-sadness and moral reasoning interacted with sympathy in predicting helping and cooperation; both sympathy and guilt-sadness were associated with the development of sharing. The findings are discussed in relation to the emergence of differential motivational pathways to helping, cooperation, and sharing.

RESUMEN

Heightened attention to sociomoral conflicts and arousal at the prospect of committing moral transgressions are thought to increase the likelihood of negatively valenced moral emotions (NVMEs; e.g., guilt) in children. Here, we tested this biphasic model of moral emotions with a psychophysiological framework. For a series of vignettes depicting moral transgressions, 5- and 8-year-olds (N=138) were asked to anticipate their emotions as hypothetical victimizers. Their responses were coded for the presence and intensity of NVMEs. In addition, their heart rate (HR) was calculated for three intervals of interest: a baseline period, the presentation of vignettes, and the anticipation of emotions following vignettes. We used multilevel modeling to examine how change in children's HR across these intervals related to the intensity of their NVMEs. Those who experienced greater HR deceleration from baseline to vignettes and greater acceleration from vignettes to anticipated emotions reported more intense NVMEs. We discuss the potential attention- and arousal-related processes behind children's physiological reactivity and anticipated emotions in contexts of moral transgression.

RESUMEN

The present longitudinal study examined the role of quality of friendship in mediating the relation of pro-sociality to self-esteem over time. Participants were 424 Italian young adults (56% females) assessed at two waves (M(age) = 21.1 at Time 1; M(age) = 25 at Time 2). An autoregressive cross-lagged panel model was used to test the mediational model. Self- and friend-report measures of pro-sociality, quality of friendship, and self-esteem were included in the analyses. Results were in line with the hypothesized paths, with quality of friendship mediating the relation of pro-sociality to later self-esteem above and beyond its high stability. Self-esteem, in turn, predicted pro-sociality 4 years later. Overall, the present findings support the potential benefits of behaving pro-socially for an actor in terms of increased perceived self-worth and also expand previous work by outlining the specific mediational role of the quality of friendships. The theoretical and practical implications of these results are discussed.

RESUMEN

Empathy has been identified as a core component of social and emotional functioning across development. Various prevention and intervention programs have utilized components of empathy-related responding to promote the development of children's and adolescents' social-emotional functioning and impede their aggression in school contexts. In this article, we assess the effectiveness of select school-based empathy interventions and the extent to which they align with developmental theory and research. First, we review current conceptualizations of empathy-related responding, identify its components, outline its normative development, and describe the need for developmentally tailored interventions. We then identify and assess the effectiveness and developmental sensitivity of 19 school-based programs with strong empirical support that target empathy-related responding across childhood and adolescence. Although the majority of these programs showed some degree of developmental differentiation between grades, none considered developmental differences within grades. Commencing interventions earlier in development and targeting higher numbers of empathy-related constructs were, in part, associated with larger effects. We discuss how future research can bridge the gap between basic developmental research and the design of developmentally tailored interventions to promote empathy-related responding.

RESUMEN

The present study examined the longitudinal relations of adolescents' self-reported ego-resiliency to their emotional self-efficacy beliefs in expressing positive emotions and in managing negative emotions as they moved into early adulthood. Participants were 239 females and 211 males with a mean age of 17 years (SD = .80) at T1, 19 years (SD = .80) at T2, 21 years (SD = .82) at T3, and 25 years (SD = .80) at T4. A four-wave cross-lagged regression model and mediational analyses were used. In a panel structural equation model controlling for the stability of the constructs, reciprocal relationships across time were found between ego-resiliency and emotional self-efficacy beliefs related to the expression of positive emotions and to the management of negative emotions. Moreover, the relation between ego-resiliency assessed at T1 and T3, and ego-resiliency assessed at T2 and T4, was mediated through emotional self-efficacy beliefs (at T2 and T3, respectively), and vice versa. The posited conceptual model accounted for a significant portion of variance in ego-resiliency and has implications for understanding the development of ego-resiliency.

RESUMEN

Prosocial behaviors are considered integral to intervention goals that seek to promote successful youth development. This study examines the effect of a school-based intervention program entirely designed to promote prosocial behaviors called Promoting Prosocial and Emotional Skills to Counteract Externalizing Problems in Adolescence (Italian acronym CEPIDEA). The CEPIDEA curriculum was incorporated into routine educational practices and included five major components that reflect the personal determinants of prosocial behavior during adolescence. The present study assessed 151 students (48.7% female; M(age) = 12.4) of the intervention school and 140 students (51.2% female; M(age) = 13.0) of the control school at three points. A multi-group latent curve analysis revealed that the intervention group, compared with the control group, showed an increase in prosocial behavior, interpersonal self-efficacy beliefs, and agreeableness along with a decrease in physical aggression above and beyond the normative developmental trend of the these variables. Participants of the intervention also obtained higher grades than the control group at the end of middle school. Moderation effects for prosocial behavior and agreeableness evidenced that those who benefited most from the intervention were those adolescents with lower normative development of prosocial behavior, low initial level of agreeableness, and high initial level of physical aggression. The results also showed that the increase of prosocial behaviors mediated the decline of verbal aggression in adolescents who had attended the intervention. These findings suggest that interventions aimed at promoting prosocial behaviors while having the potential to support positive outcomes may also counteract or redirect negative trajectories of functioning.

RESUMEN

The current study explored the prediction of civic engagement by diverse trajectories of prosocial behaviors as well family dynamics (i.e., filial self-efficacy and relational parent-child support) across four times of assessment (from age 16-17 to age 22-23) during the transition to adulthood. Three different trajectories of prosocial behaviors were identified for 686 Italian youths: high-increasing (18%), medium-stable (48%), and low-stable (34%). An increasing pattern of change in prosocial behaviors was predicted by filial self-efficacy at age 16-17, which in turn mediated longitudinal relations to civic engagement and civic values at age 22-23. Results highlighted that during the transition to adulthood youths' beliefs about their ability to negotiate with their parents without losing autonomy and relatedness are relevant in promoting prosocial behaviors and civic involvement, especially in the context of Mediterranean countries.

RESUMEN

The goal of this study was to identify heterogenic longitudinal patterns of change in prosocial behavior from adolescence to early adulthood and their association with change in Big Five Factor (BFF) personality traits from adolescence until early adulthood. Participants were 573 Italian adolescents aged approximately 13 at the first assessment and 21 at the last assessment. Using growth mixture modeling, low increasing (LI; 18%), medium quadratic (MQ; 26%), and high quadratic (HQ; 54%) trajectories of prosocial behavior were distinguished. Generally, the LI trajectory group predicted an increase in Conscientiousness over time, whereas the HQ trajectory group predicted greater change in Agreeableness and Openness. In addition, positive changes in Conscientiousness, Agreeableness, and Openness between ages 13 and 21 predicted a higher probability of belonging to the HQ prosocial group. Findings support a malleable perspective on personality and identify longterm positive pathways for youths' prosocial development.

RESUMEN

This study examined links between inhibitory control, moral emotions (sympathy and guilt), and reparative behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 162). Caregivers reported their children's reparative behavior, inhibitory control, and moral emotions through a questionnaire, and children reported their guilt feelings in response to a series of vignettes depicting moral transgressions. A hypothesized meditation model was tested with inhibitory control relating to reparative behavior through sympathy and guilt. In support of this model, results revealed that high levels of inhibitory control were associated with high levels of reparative behavior through high levels of sympathy and guilt. However, the mediation of inhibitory control to reparation through guilt was significant for 4-year-olds only. Results are discussed in relation to the temperamental, regulatory, and affective-moral precursors of reparative behavior in early and middle childhood.

RESUMEN

OBJECTIVE: The present longitudinal study examined the development of self-reported prosociality (i.e., the tendency to enact prosocial behaviors) from adolescence to early adulthood and its prediction from teacher-reported effortful control (i.e., dispositional regulation) at age 13. METHOD: Participants were 573 (276 girls) Italian adolescents aged approximately 13 (M = 12.98, SD = 0.80) at the first assessment and 21 (M = 21.23, SD = 0.67) at the last assessment. The study used three different cohorts recruited across ten years (from 1994 to 2004) from a larger longitudinal project with a multiple-cohort design. RESULTS: Latent growth curve modeling indicated that the overall level of prosociality declined until approximately age 17 with a subsequent slight rebound until age 21. Significant inter-individual variability in developmental trends of prosociality in males and females was observed. Youths' effortful control was related to a lesser decline of prosociality in adolescence. CONCLUSIONS: Being able to regulate one's own emotions and behaviors in early adolescence may not only affect the tendency to behave prosocially, but also counter the self-centered tendencies observed across this phase of development.
