Sibling correlates of young adults' status attainment: ethnic group differences

I used longitudinal data to examine relationships between sibling variables and young adults' status attainment at different levels, based on earlier measures of adolescents' educational and occupational aspirations. My analyses involved 21-year-old Australians from Anglo-Australian, Greek, and Southern Italian families. Regression surfaces were plotted from models that included terms to test for possible linear, interaction, and curvilinear associations among the variables. My study showed that the number of children in a family and birth order continue to be significantly associated with young adults' status attainment, even after incorporating the mediating influences of adolescents' aspirations. The investigation also suggested ethnic group differences among sibling variables, adolescents' aspirations, and young adults' status attainment.

Sibling dilution hypothesis: a regression surface analysis.

This study examined relationships between sibship size (the number of children in a family), birth order, and measures of academic performance, academic self-concept, and educational aspirations at different levels of family educational resources. As part of a national longitudinal study of Australian secondary school students data were collected from 2,530 boys and 2,450 girls in Years 9 and 10. Regression surfaces were constructed from models that included terms to account for linear, interaction, and curvilinear associations among the variables. Analysis suggests the general propositions (a) family educational resources have significant associations with children's school-related outcomes at different levels of sibling variables, the relationships for girls being curvilinear, and (b) sibling variables continue to have small significant associations with affective and cognitive outcomes, after taking into account variations in family educational resources. That is, the investigation provides only partial support for the sibling dilution hypothesis.     

The Sibling Resource Dilution Theory: An Analysis

In this study, I examined relationships between sibling variables and children's family educational resources at different levels of family social status and children's intellectual ability. Data were collected from 900 eleven-year-old Australian children (450 boys, 450 girls) and their parents. Relationships among the variables were examined by plotting regression surfaces generated from models that included terms to test for possible linear, interaction, and curvilinear associations. Although results from some of the regression models provided tentative support for the sibling resource dilution theory, overall results suggest that acceptance of the theory must be treated with some caution. In general, the analysis indicated the possible complexity of relationships between sibling variables and family educational resources.     

Sibling variable correlates of children's academic achievement: family-group differences

The study examined the proposition that relationships among sibling variables, intellectual ability, and academic achievement vary for children from different family-environment groups. Data were collected from 900 11-yr.-old Australian children and their parents. In the analysis, the children were classified into four family contexts that were defined conjointly by family social status and parents' academic socialization. Within each family group, regression surfaces were constructed from models that included terms to account for possible linear, interaction, and curvilinear associations among the variables. The results suggested the general proposition that within the family-environment groups, sibling variables were not related to academic achievement at different levels of children's ability. However, the findings indicated that there were variations to this general proposition. Indeed, there were a number of complex associations between the sibling variables and children's academic achievement in the different family-environment groups.     

Sibling support in early adolescence: Buffering and compensation across relationships

The current study is an examination of how support from siblings relates to psychological adjustment and academic competence in early adolescence, with a focus on the buffering and compensatory effects of sibling support. Participants were 695 (357 female and 338 male) African-American, Hispanic-American and European-American students in grades 5 through 8. The age range was 11 to 15 (M?=?12.69, SD?=?1.12). Participants were interviewed in school regarding their social support in addition to their familial, economic and environmental risk, psychological wellbeing, and academic competence. Brother support was associated with more positive school attitudes and with higher self-esteem. Sister support buffered the relationship between ecological risk and school adaptation. In terms of a compensatory effect, students under low mother support conditions receiving greater support from brothers exhibited higher school achievement. The current study highlights the importance of examining constellation variables as part of the broader interest in sibling relations. Additionally, the current study indicates that the variability in sibling relationships reported in the literature may be associated with developmental changes in these relationships. The potential benefits of sibling support warrant a closer examination of the wide-ranging issues involved in sibling relations.     

Genetic and environmental influences on the relationships between family connectedness, school connectedness, and adolescent depressed mood: sex differences.

This study investigated (a) genetic and environmental contributions to the relationship between family and school environment and depressed mood and (b) potential sex differences in genetic and environmental contributions to both variation in and covariation between family connectedness, school connectedness, and adolescent depressed mood. Data are from 2,302 adolescent sibling pairs (mean age = 16 years) who were part of the National Longitudinal Study of Adolescent Health. Although genetic factors appeared to be important overall, model-fitting analyses revealed that the best-fitting model was a model that allowed for different parameters for male and female adolescents. Genetic contributions to variation in all 3 variables were greater among female adolescents than male adolescents, especially for depressed mood. Genetic factors also contributed to the correlations between family and school environment and adolescent depressed mood, although, again, these factors were stronger for female than for male adolescents.     

Parents,Siblings, or Friends? Exploring Life Satisfaction among Early Adolescents

This study analyzes 2,617 10–15 year olds surveyed in wave 1 of the United Kingdom Household Longitudinal Study (UKHLS). Specifically, it tests the associations of three variables with life satisfaction among early adolescents: parent–child relationship quality, being a perpetrator or victim of sibling bullying, and being a perpetrator or victim of friend bullying. The results suggest that all of these social relationships have significant associations with life satisfaction, both individually and in combination. Of the three, parent–child relationship quality explained the most variance in predicting life satisfaction. This is followed by friend victimization (i.e., being bullied by friends), whereas the influence of sibling victimization is significant but not as strong. This study also tests the interaction effects between parent–child relationship quality, sibling bullying, and friend bullying. The association of parent–child relationship quality with life satisfaction is found to be stronger among adolescents who were either victims of sibling bullying or of friend bullying, highlighting the protective importance of parent–child relationship quality. Lastly, when testing whether the influences of sibling bullying, friend bullying, and parent–child relationship quality vary between male and female adolescents, this study finds some significant gender differences. Specifically, the positive associations of lower friend victimization and better parent–child relationship quality with life satisfaction are found to be stronger among female adolescents.     

Sibling relationships in adolescence: Learning and growing together

In this article, I discuss the reasons for my interest in sibling relationships, and showcase studies on sibling relationships in adolescence carried out with my colleagues and students, in the context of the broader literature on sibling relationships. Our studies have focused on a number of important issues concerned with sibling relationships. First, I report on the associations between sibling relationships and other family relationships and the ways that the various family relationships affect each other. Second, I report a study of sibling relationships in the context of parental separation and divorce and show that sibling relationships in these families are more likely to be high in both warmth and hostility than is true for relationships in 2‐parent families. Third, I report on several data sets showing an association between the quality of sibling relationships and adolescent adjustment and the link between differential parenting, adolescent adjustment, and the quality of the sibling relationship. Fourth, I report on a study of comparison and competition in sibling relationships and the associations between sibling relationship quality and reactions to being outperformed by a sibling. Finally, I discuss possible future directions for research on sibling relationships, including the importance of multimethod studies and a longitudinal perspective.     

Sibling relationships during adolescence

The principal objective of this study was to analyse sibling relationships during adolescence, within the context of parent and peer relationships, and their link with socioemotional adjustment. To this end, 513 adolescents aged between 13 and 19 completed instruments relating to parent?–?child relationships, sibling adjustment, relationships with peers, self-esteem and life satisfaction. We found important gender-based differences in the meaning and importance that sibling adjustment seems to have for adolescents. For girls, a good relationship with their siblings was linked to good relationships with their parents and peers, as well as increased self-esteem and life satisfaction. For boys, sibling relationships had no relation with other family or personal variables.     

Level of commitment,mutuality of commitment,and couple well-being

Interdependence theory identifies level of dependence and mutuality of dependence as two key properties of interdependent relationships. In ongoing relationships, these structural properties are subjectively experienced in terms of commitment–dependence level is experienced as greater or lesser commitment level, and mutuality of dependence is experienced as greater or lesser perceived mutuality in partners’commitment levels. We examined the associations of these variables with couple well-being using data from two three-wave longitudinal studies. One study examined partners in dating relationships and the second study examined partners in marital relationships. Consistent with predictions, both level of commitment and perceived mutuality of commitment accounted for unique variance in couple well-being: Couples exhibited greater adjustment to the degree that the partners were highly committed to their relationship and to the degree that their commitment levels were mutual. Mediation analyses revealed that the association of mutuality of commitment with couple well-being is partially mediated by negative affect (e.g., anxiety, guilt) and partially to wholly mediated by trust level; perceived mutuality of power is not a reliable mediator of this association.     

Young adult sibling relations: the effects of perceived parental favoritism and narcissism

The present study examined predictors of siblings' relations in 202 young adults (aged 21-32 years), who completed the Adult Sibling Relationship Questionnaire and the Narcissistic Personality Inventory. Results indicate that warmth between siblings is explained by gender (with women feeling closer), perceived paternal favoritism, low levels of narcissism, and an interaction suggesting that paternal favoritism moderates the link between narcissism and sibling warmth. Conflict between siblings was explained by gender (sisters), age, parental favoritism, high levels of narcissism, extreme levels of similarity or dissimilarity between siblings, and interactions indicating that older age is a predictor of conflict between siblings among women but not among men. The impact of parental favoritism and narcissism on sibling relationships in young adulthood was discussed.

Results indicate that warmth between siblings is explained by gender (with women feeling closer), perceived paternal favoritism, low levels of narcissism, and an interaction suggesting that paternal favoritism moderates the link between narcissism and sibling warmth. Conflict between siblings was explained by gender (sisters), age, parental favoritism, high levels of narcissism, extreme levels of similarity or dissimilarity between siblings, and interactions indicating that older age is a predictor of conflict between siblings among women but not among men. The impact of parental favoritism and narcissism on sibling relationships in young adulthood was discussed.     

Is episodic memory performance more vulnerable to depressive affect in older adulthood?

This study examined how age, depressive symptoms, demographic variables, frailty, and health factors jointly influence episodic memory across the lifespan in two large, diverse samples. Hierarchical regression analyses from both samples showed that depressive symptoms negatively impacted episodic memory performance with the effect being more pronounced for older adults. Health and frailty tended not to be associated with episodic memory. However, the main effect of depressive symptoms tended to remain significant over and above other predictors, while the interaction with age was weakened with the addition of demographic variables. The unique contribution of this study is demonstrating that the relationship between depressive symptoms and episodic memory is moderated by age across relatively large non-clinical lifespan samples of adults. The findings indicate the importance of measuring and studying depressive symptoms during the course of aging in order to better understand the complex relationship between age, affect, physical functioning, and memory.     

Growing Up with an Anxious Sibling: Psychosocial Correlates and Predictors of Sibling Relationship Quality

Relationships between young people with anxiety and their non-affected siblings are important for both individuals in the dyad, and for family dynamics throughout the lifespan; however, these relationships are not well understood. This study examined the experience of growing up with an anxious sibling from the sibling without anxiety’s point of view. We measured psychosocial factors associated with sibling relationship quality in 64 young adults with an anxious sibling. Overall, participants with anxious siblings were resilient, reporting comparable sibling relationship quality, anxiety symptoms, and psychological functioning relative to peers without anxious siblings. The contributions of caregiver burden and attributions about the causes of the sibling’s anxiety-related behavior accounted for significant variance in both sibling relationship warmth/closeness and conflict, with responsibility attributions emerging as an individual predictor of conflict. Clinical and research implications for understanding sibling relationships in the context of anxiety, and for the role of attributions in family relationships are considered.     

儿童的同伴交往与孤独感:一项2年纵向研究

用提名法和问卷法对小学的3、4年级274名儿童进行两年追踪调查,采用交叉滞后设计,考察了同伴交往4个特征水平上的变量与孤独感的相互预测关系。结果发现：（1）自我报告的同伴交往变量——友谊质量和社交自我知觉与孤独感之间的交叉滞后效应显著;而同伴评定的同伴交往变量——积极提名、消极提名、受同伴欺负、消极退缩与孤独感之间的交叉滞后效应不显著;另外,前测的互选朋友数能显著负向预测后测的孤独感,前测的孤独感不能显著预测后测的互选朋友数。（2）在排除了早期其它变量的效应之后,积极提名分、消极提名分、受同伴欺负得分、消极退缩得分、互选朋友数在两年之间仍然呈现出高度的稳定性;友谊质量和社交自我知觉以及孤独感则表现出中等程度的稳定性     

Parentification of Adult Siblings of Individuals with Autism Spectrum Disorder

Many typically-developing (TD) siblings provide care for their siblings with autism spectrum disorder (ASD), both as children and as adults. Research on parentification (i.e., when children assume responsibilities typically reserved for adults) has been mixed, with some studies supporting positive outcomes for TD siblings and others indicating negative outcomes. Some of these discrepancies may be due to inconsistencies in differentiating types of parentification. The current study examined how different types of parentification during childhood (retrospectively-reported) related to distress outcomes and attitudes about sibling relationships among 41 TD adult siblings of individuals with ASD. Results indicated that parent-focused parentification was positively related with anxiety and stress among TD siblings. Sibling-focused parentification was positively related to stress but was also related to more positive sibling relationship attitudes. Accounting for demographic variables and the other form of parentification, parent-focused parentification was a unique predictor of distress, whereas sibling-focused parentification was a unique predictor of positive sibling relationship attitudes. Although parentification is often viewed negatively, sibling-focused parentification and perceived benefits of parentification may predict positive outcomes. Results suggest that parentification may prove important in understanding the complex nature of sibling relationships. Specifically, strengthening the sibling bond and reducing parent-focused parentification during childhood may curtail sibling relationship problems and general distress in TD siblings later in life.     

Older sibling correlates of younger sibling drug use in the context of parent-child relations

The purpose of this study was to examine older brother correlates of younger brother drug use in the context of parental influences and younger brother personality. The sample consisted of 278 White male college students and their oldest brothers, who volunteered to answer self-administered questionnaires. Results indicated that 3 domains of influence each had an independent impact on younger brother drug use: (a) parent-younger brother relationships and parent drug use, (b) older brother-younger brother relationships and older brother drug use, and (c) younger brother personality. Modeling of nondrug use and a strong attachment relationship in the parent-younger brother and sibling dyads, as well as younger sibling traits of conventionality, had strong links to low younger brother drug use. Our findings highlight the importance of modeling and mutual parent-child attachment relationships as well as sibling relationships as they relate to the possible etiology of drug use.     

Longitudinal Impact of Communication Patterns on Romantic Attachment and Symptoms of Depression

This study investigated how communication patterns, romantic attachment, symptoms of depression, and perceptions of relationship quality are related concurrently and prospectively within monogamous dating relationships. Participants completed two self-report assessments at six-month intervals. Hierarchical regression analyses revealed that for males, mutual constructive communication was associated with decreases in depressive symptoms, whereas demand-withdraw communication was associated with increases in attachment avoidance and depressive symptoms from T1 to T2. The same variables were not associated with changes in attachment or depressive symptoms for females. Mixed model ANOVAs revealed insecure attachment, symptoms of depression, and negative perceptions of relationship quality were significantly higher for broken up individuals than for those whose relationships remained intact.     

Servant leadership effectiveness: do religious atmosphere and housing price matter? social information-processing Perspective

Leadership effectiveness is a result of the interaction between leadership style and the social and organizational environment. We draw on social information-processing theory and analyze how the interaction between servant leadership and the social environment (i.e., religious atmosphere and housing price in one region) influences employee behavior. We likewise measure geographic-proximity-based religious atmosphere and housing price variables on the basis of 25 geographically disparate branches of a company, including a sample of 82 supervisors and 351 employees. Multilevel analyses reveal that the interaction between servant leadership and religious atmosphere has a positive effect on employee helping behavior but not for employee voice behavior. Conversely, the interaction between servant leadership and housing price has a positive effect on employee voice behavior, but does not have such effect on employee helping behavior. We also discuss the theoretical and practical implications on leadership research.
