Realationship between personality impulsivity and aggressivity in adolescents： the effecting path of sibling relationships / 四川精神卫生

BackgroundIn China， the structure shift from just one-child family to both one-child and more-than-one-child families is happening. Exploring how the sibling relationships effect between adolescent personality impulsivity and aggressivity is of great significance for promoting adolescent mental health as well as maintaining social harmony and stability. ObjectiveTo investigate the effecting path of sibling relationships between personality impulsivity and aggressivity in adolescents， so as to provide references for the prevention of violent and aggressive behavior in adolescents. MethodsFrom February to April， 2023， a total of 1 200 students with sibling relationships from 12 primary and secondary schools in a county of Sichuan province were included by random sampling. Barratt Impulsivity Scale （BIS-11）， Chinese Version of Buss & Perry Aggression Questionnaire （AQ-CV）， and Sibling Relationship Questionnaire （SRQ） were used for cross-sectional investigation. Pearson Correlation Analysis was used to analyze the correlation between the scores of these scales. Bootstrap method was used to test the effecting path of sibling relationships between personality impulsivity and aggressivity. ResultsThe total score of BIS-11 was positively correlated with that of AQ-CV as well as the scores of conflict and competition dimensions in SRQ （r=0.485、0.276、0.280，P<0.01）， while negatively correlated with the score of warmth/intimacy dimension in SRQ （r=-0.383， P<0.01）. The total score of AQ-CV was positively correlated with the scores of conflict and competition dimensions in SRQ （r=0.387， 0.340， P<0.01）， while negatively correlated with the score of warmth/intimacy dimension in SRQ （r=-0.304， P<0.01）. Within SRQ， negative correlations could be observed between the score of warmth/intimacy and scores of conflict and competition （r=-0.307， -0.375， P<0.01）， whereas positive correlation could be observed between the score of conflict and that of competition （r=0.267， P<0.01）. The total effect of personality impulsivity level on aggressivity level in adolescent was 0.480 （P<0.01）. Sibling relationships played a mediating role between personality impulsivity and aggressivity in adolescents. Meanwhile， the indirect effect values of warmth/intimacy， conflict and competition were 0.054， 0.075 and 0.062， with the effect values accounting for 11.21%， 15.70% and 12.93%， respectively. ConclusionThe personality impulsivity of adolescents can directly affect their aggressivity， and sibling relationships may act as an important channel connecting personality impulsivity and aggressivity. ［Funded by 2023 Project of the Psychology and Behavioral Science Research Center of the Deyang Federation of Social Sciences （number， XLYXW2023305）］

Effect of parent-child cohesion on internalizing problems of junior high school students: the mediating role of self-esteem and the moderating role of sibling relationships / 中华行为医学与脑科学杂志

Objective:To explore the effect of self-esteem and sibling relationships on the links of parental cohesion and internalizing problems in junior high school students based on the family system theory.Methods:A total of 565 junior high school students were investigated with the sibling relationship questionnaire, parent-child cohesion questionnaire, self-esteem scale and internalizing problems questionnaire from April to June 2021.SPSS 26.0 was used for descriptive statistics and Pearson correlation analysis.PROCESS was used to examine the mediating and moderating effect.Results:Maternal-child cohesion was positively correlated with self-esteem and sibling warmth ( r=0.36, 0.58, both P<0.01), while it was negatively correlated with internalizing problems and sibling conflict ( r=-0.29, -0.25, both P<0.01). Similarly, paternal-child cohesion was positively correlated with self-esteem and sibling warmth ( r=0.37, 0.51, both P<0.01), and it was negatively correlated with internalizing problems and sibling conflict ( r=-0.36, -0.21, both P<0.01). The self-esteem played a partial mediating role between maternal-child cohesion and internalizing problems ( β=-0.09, 95% CI=-0.14--0.05), and the mediating value was 30.13%.The self-esteem also played a partial mediating role between paternal-child cohesion and internalizing problems ( β=-0.07, 95% CI=-0.11--0.04), and the mediating value was 25.36%.Sibling warmth could improve the positive effect of maternal-child cohesion on self-esteem ( β=0.06, 95% CI=0.01-0.11), while could offset the negative effects of low level of maternal-child cohesion against the internalizing problems ( β=0.10, 95% CI=0.04-0.16). But sibling conflict did not significantly predict the effects of maternal-child cohesion on self-esteem and internalizing problems.Similarly, sibling warmth could improve the positive effect of paternal-child cohesion on self-esteem ( β=0.05, 95% CI=0.01-0.09), while could offset the negative effects of low level of paternal-child cohesion against the internalizing problems ( β=0.09, 95% CI=0.03-0.15). But sibling conflict could reduce the positive impact of paternal-child cohesion and self-esteem ( β=-0.05, 95% CI=-0.09--0.01), while had no effect on the impact of paternal-child cohesion and internalizing problems. Conclusion:Parent-child cohesion not only directly affects the internalizing problems, but also indirectly affects the internalizing problems through the self-esteem.Positive parent-child cohesion and sibling warmth relationships can improve the individual's self-esteem level and reduce the internalizing problems.

Reliability and Validity of the Korean Version of the Lifespan Sibling Relationship Scale

The sibling relationship and its potential impact on neurodevelopment and mental health are important areas of neuroscientific research. Validation of the tools assessing the quality of the sibling relationship would be the first essential step for conducting neurobiological and psychosocial studies related to the sibling relationship. However, to the best of our knowledge, no sibling relationship assessment tools have been empirically validated in Korean. We aimed to evaluate the psychometric properties of the Korean version of the Lifespan Sibling Relationship Scale (LSRS), which is one of the most commonly used self-report questionnaires to assess the quality of the sibling relationship. A total of 109 adults completed a series of self-report questionnaires including the LSRS, the mental health subscale of the Medical Outcomes Study-Short Form 36 version 2 (SF36v2), the Satisfaction with Life Scale (SLS), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). The internal consistency, subscale intercorrelations, one-week test-retest reliability, convergent validity, divergent validity, and the construct validity were assessed. All six subscale scores and the total score of the LSRS demonstrated good internal consistency (Cronbach's alpha=0.85-0.94) and good test-retest reliability (intraclass correlation coefficient=0.77-0.92). Correlations of the LSRS with the SF36v2 mental health score (r=0.32, p=0.01) and with the SLS (r=0.27, p=0.04) supported the good convergent validity. The divergent validity was shown by the non-significant correlation of the LSRS with the MC-SDS (r=0.15, p=0.26). Two factors were extracted through factor analysis, which explained 78.63% of the total variance. The three Adult subscales loaded on the first factor and the three Child subscales loaded on the second factor. Results suggest that the Korean version of the LSRS is a reliable and valid tool for examining the sibling relationship.

Relação fraterna: constituição do sujeito e formação do laço social / Sibling relationships: Subjects' constitution, and the establishment of social ties / Relation fraternelle: constitution du sujet et formation du lien social / Relación fraterna: constitución del sujeto y formación del lazo social

Apesar da importância do irmão na constituição do sujeito e na formação do laço social, somente por volta do ano 2000 os autores contemporâneos passaram a mostrar um interesse maior pelo estudo da relação fraterna. Grande parte desses estudos, entretanto, se dedica mais à competição e rivalidade do que à boa convivência e solidariedade. Em nossa revisão teórica, realizada na abordagem psicanalítica, de autores contemporâneos, fazemos um estudo da relação fraterna, em seus aspectos de solidariedade e de companheirismo. Constatamos a importância da boa convivência na fratria para a constituição do sujeito e do laço social. Ilustramos a discussão teórica com fragmentos de casos clínicos.

Despite the relevance of siblings in the subject’s constitution and the establishment of social ties, it has been only since the year 2000 that contemporary authors begin to show interest in the study of sibling relationships. Most of these studies, however, focus primarily on competition rather than on good quality coexistence and solidarity. In our theoretical review of contemporary authors - based on a psychoanalytic approach -, we conduct a study on sibling relationships in their companionship and solidarity aspects. We attest for the relevance of good quality of siblings’ coexistence in both the constitution of the subject and the social ties. The theoretical discussion is illustrated by fragments of clinical cases.

En dépit de l’importance de la fratrie dans la constitution du sujet et de la formation du lien social, ce n’est qu’autour de l’an 2000 que les auteurs contemporains ont manifesté un plus grand intérêt pour l’étude de la relation fraternelle. Ces études y sont toutefois soucieuses, pour la plupart d’entre elles, des rapports de compétition et de rivalité, plus que de ceux de convivance et de solidarité. Nous nous sommes attachés, quant à nous, dans notre révision théorique d’auteurs contemporains, relevant d’une approche psychanalytique, à réaliser une étude de la relation fraternelle, dans ses aspects de solidarité et de camaraderie. Nous y avons constaté l’importance de la bonne convivialté dans la fratrie pour la constitution du sujet et du lien social. Nous en avons illustré la discussion théorique par des fragments de cas cliniques.

Interação entre irmãos: deficiência mental, idade e apoio social da família / Siblings' interaction: mental disability, age and family social support

Os objetivos deste estudo foram: (a) caracterizar a interação entre díades de irmãos, divididas em dois grupos - G1, com o irmão deficiente mental pré-adolescente, e G2, com esse irmão adulto; (b) comparar os desempenhos dos grupos nas interações; e (c) avaliar diferenças entre os grupos nas interações, considerando o apoio social da família. Foram realizadas sessões de observação de interações, e aplicação de instrumentos de auto-relato; os cuidadores responderam escalas para avaliação do apoio social. Os resultados sugeriram diferença no comportamento de ajudante do irmão com desenvolvimento típico, com taxa de ocorrência maior para G1. Nas escalas, houve diferença estatisticamente significativa na Escala de Apoio à Maternidade/Paternidade, revelando-se menor apoio para G1. Especula-se que, como as famílias do G1 recebem menor apoio deste nível, há maior demanda de ajuda requerida pelo filho deficiente, que pode ser suprida pelos irmãos menores com desenvolvimento típico, que desempenham o papel de ajudante em maior escala que os adultos.

The purpose of the present study was: (a) To describe the relationship in sibling's dyads, separated in two groups - G1, with pre-adolescent mentally retarded sibling, and G2, with this adult sibling; (b) To compare the performance of both groups in the interactions; and (3) To evaluate differences in the relationships between the groups when family social support is taken into account. Sessions of sibling's interactions were videotaped, and self-report instruments were used. The caretakers answered scales of social support. Results suggested differences concerning the behavior of the helper of the sibling with characteristic development, with highest occurrence in G1. Scales' results indicated statistically significant difference for the Parenting Support from Family/Friends Scale, showing less support for G1. It is possible to suggest that because families from G1 have less support from this level from families and friends, a bigger demand of help is required from the disabled member, which can be compensated by the young siblings with typical development, who perform the helper's role in greater level than the adults.
