Challenging the Stereotypes About Only Children: A Review of the Literature and Implications for Practice

Defining and Identifying Only Children: A Research Note on the Concept and Measurement Illustrated With UK Survey Data

Despite increasing interest in the circumstances and outcomes of only children in the demographic literature, the conceptualization of this group has received limited scholarly attention. This research note argues for greater engagement by demographers and social scientists in the conceptualization and identification of only children by addressing three aims. First, we outline potential definitions of only children, present a framework to guide researchers' decisions, and evaluate whether only children can be reliably identified using the British birth cohort studies. Second, we show that the prevalence estimates are contingent on the timing of measurement in childhood, indicating the need for caution when deriving only-child status from cross-sectional household grid data. Third, we demonstrate that both the size and the characteristics of the only-child group may differ across definitions, highlighting that the accurate operationalization of some definitions is particularly restricted by survey designs that prioritize mothers for data collection on children and families. We argue that researchers interested in sole children's outcomes must choose the most appropriate measure for a given research question and, given that many datasets limit how accurately any indicator of only children can capture the chosen definition, reflect on how the operationalization of their measure might affect the results.

Long-Lasting Effects of Changes in Daily Routine during the Pandemic-Related Lockdown on Preschoolers’ Language and Emotional–Behavioral Development: A Moderation Analysis

The quantity and quality of environmental stimuli and contexts are crucial for children’s development. Following the outbreak of SARS-CoV-2 (COVID-19), restrictive measures have been implemented, constraining children’s social lives and changing their daily routines. To date, there is a lack of research assessing the long-lasting impacts that these changes have had on children’s language and emotional–behavioral development. In a large sample of preschoolers (N = 677), we investigated (a) the long-lasting effects of changes in family and social life and in daily activities over the first Italian nationwide COVID-19-pandemic-related lockdown upon children’s linguistic and emotional–behavioral profiles and (b) how children’s demographic variables and lifelong family characteristics moderated these associations within a multiple-moderator framework. Our findings showed a relationship between the time spent watching TV/playing video games and affective problems that was moderated by the number of siblings. Our findings showed that children who could be at high risk in more normal circumstances, such as only children, have been particularly harmed. Therefore, assessing the long-term effects of lockdown-related measures and how these could have been moderated by potential risk/protective factors added significant information to the existing literature.

Health outcomes of only children across the life course: An investigation using Swedish register data

Only children (with no full biological siblings) are a growing subgroup in many high-income settings. Previous studies have largely focused on the short-term developmental outcomes of only children, but there is limited evidence on their health outcomes. Using Swedish population register data for cohorts born 1940-75, we compare the health of only children with that of children from multi-child sibling groups, taking into account birth order, family size, and presence of half-siblings. Only children showed lower height and fitness scores, were more likely to be overweight/obese in late adolescence, and experienced higher later-life mortality than those with one or two siblings. However, only children without half-siblings were consistently healthier than those with half-siblings, suggesting that parental disruption confers additional disadvantages. The health disadvantage was attenuated but not fully explained by adjustment for parental characteristics and after using within-family maternal cousin comparison designs.

Multicenter analysis on the non-suicidal self-injury behaviors and related influencing factors-A case study of left-behind children in northeastern Sichuan

BACKGROUND

Few studies have been conducted focusing on the non-suicidal self-injury (NSSI) incidence rate and influencing factors among left-behind children in northeastern Sichuan, China. In this study, we investigated the incidence rate of the NSSI behaviors, levels of anxiety and depression in left-behind children in northeastern Sichuan, and relevant sociodemographic factors.

METHODS

The NSSI behaviors were identified using the Ottawa Self-injury Inventory (Chinese version). Its incidence rate and related influencing factors were evaluated by Cluster sampling; the Depression Anxiety Stress Scale-21 Items (DASS-21) was adopted to assess the levels of anxiety, depression, and stress.

RESULTS

A total of 9450 adolescents met the inclusion criteria, including 543 with NSSI behaviors, and the prevalence of NSSI was 5.7 %. There were 3596 left-behind children, and 243 of them had NSSI behaviors, the NSSI incidence in left-behind children was 6.8 %. There were 5854 non-left-behind children, and the NSSI incidence in non-left-behind children was 5.1 %. Left-behind children's NSSI behaviors were remarkably correlated with five risk factors: being female (OR = 2.411, 95%CI = 1.773-3.279), parents' divorce (OR = 1.742, 95%CI = 1.262-2.404), elder age (OR = 1.120, 95%CI = 1.028-1.219), severe depression (OR = 1.212, 95%CI = 1.148-1.281), and high anxiety (OR = 1.170, 95%CI = 1.093-1.251).

LIMITATIONS

This is a cross-sectional study, we cannot probe into the causality between NSSI behaviors and corresponding risk factors. Reporting and recalling biases may be unavoidable as questionnaires are performed by self-rating scales and retrospective reports.

CONCLUSION

The NSSI behaviors are common in left-behind children in northeastern Sichuan. This study proposes that prevention and intervention measures are necessary for the healthy growth of such children.

Post-traumatic stress disorder and depressive symptoms among firefighters: a network analysis

Background

Firefighters, as first responders with a high risk of occupational exposure to traumatic events and heavy working stress, have a high prevalence of PTSD symptoms and depressive symptoms. But no previous studies analyzed the relationships and hierarchies of PTSD and depressive symptoms among firefighters. Network analysis is a novel and effective method for investigating the complex interactions of mental disorders at the symptom level and providing a new understanding of psychopathology. The current study was designed to characterize the PTSD and depressive symptoms network structure in the Chinese firefighters.

Method

The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) and the Self-Rating Depression Scale (SDS) were applied to assess PTSD and depressive symptoms, respectively. The network structure of PTSD and depressive symptoms was characterized using "expected influence (EI)" and "bridge EI" as centrality indices. The Walktrap algorithm was conducted to identify communities in the PTSD and depressive symptoms network. Finally, Network accuracy and stability were examined using the Bootstrapped test and the case-dropping procedure.

Results

A total of 1,768 firefighters were enrolled in our research. Network analysis revealed that the relationship between PTSD symptoms, "Flashback" and "Avoidance," was the strongest. "Life emptiness" was the most central symptom with the highest EI in the PTSD and depression network model. Followed by "Fatigue" and "Interest loss." Bridge symptoms connecting PTSD and depressive symptoms in our study were "Numb," "High alertness," "Sad mood," and "Compunction and blame," successively. The data-driven community detection suggested the differences in PTSD symptoms in the clustering process. The reliability of the network was approved by both stability and accuracy tests.

Conclusion

To the best of our knowledge, the current study first demonstrated the network structure of PTSD and depressive symptoms among Chinese firefighters, identifying the central and bridge symptoms. Targeting interventions to the symptoms mentioned above may effectively treat firefighters suffering from PTSD and depressive symptoms.

Sibling group size and BMI over the life course: Evidence from four British cohort studies

Only children, here defined as individuals growing up without siblings, are a small but growing demographic subgroup. Existing research has consistently shown that, on average, only children have higher body mass index (BMI) than individuals who grow up with siblings. How this difference develops with age is unclear and existing evidence is inconclusive regarding the underlying mechanisms. We investigate BMI trajectories for only children and those with siblings up to late adolescence for four British birth cohorts and across adulthood for three cohorts. We use data on BMI from ages 2-63 years (cohort born 1946); 7-55 years (born 1958); 10-46 (born 1970) and 3-17 years (born 2000-2002). Using mixed effects regression separately for each cohort, we estimate the change in BMI by age comparing only children and those with siblings. The results show higher average BMI among only children in each cohort, yet the difference is substantively small and limited to school age and adolescence. The association between sibling status and BMI at age 10/11 is not explained by differential health behaviours (physical activity, inactivity and diet) or individual or family background characteristics in any of the cohorts. Although persistent across cohorts, and despite the underlying mechanism remaining unexplained, the substantively small magnitude of the observed difference and the convergence of the trajectories by early adulthood in all cohorts raises doubts about whether the difference in BMI between only children and siblings in the UK context should be of research or clinical concern. Future research could usefully be directed more at whether only children experience elevated rates of disease, for which high BMI is a risk factor, at different stages of the life course and across contexts.

Is Two Still Best? Change in Parity-Specific Fertility Across Education in Low-Fertility Countries

The dominance of two-child families is considered an intrinsic characteristic of low fertility societies. Their share was continuously increasing among baby boom cohorts but the rise ceased afterwards. While parity- and education-specific fertility trends during the expansion of the two-child families have been studied, corresponding analyses of developments in the post-expansion birth cohorts are scarce. This study investigates the parity-specific fertility trends that ended the expansion of two-child families across educational groups. We use data on completed fertility of female cohorts born between 1936 and 1970 in 16 low-fertility countries. Besides examining trends in education- and parity-specific fertility, we provide evidence on increasing variation in family size and on the contribution of parity-specific fertility to the share of two child families among women with low, medium and high education. Our results show that the expansion of two-child families stopped as the variation in family size increased: transition rates to first and/or second birth declined whereas those to third birth increased. This polarisation process was strongest among women with low education. Apparently, as the number of women progressing to second birth declined, they became more selected and family-oriented, and thus more likely to progress to further births. The fact that the strongest polarisation of fertility was observed among the low educated reflects the group’s increasing selectivity. We demonstrate that rising polarisation of family size is a common development to most high-income low-fertility populations, especially among the low educated, regardless of substantial cross-country differences in fertility levels as well as in institutional, economic and cultural settings.

Patterns of help and care by adult only children and children with siblings

Adult children with siblings can share caring for older parents but adult only children face this responsibility alone. Given increased longevity and reliance on informal care-giving, as well as an increase in one-child families, there is a need to investigate only children's care-giving further. Using data from three large-scale British birth cohorts, this paper investigates patterns of parent-care, care intensity and wellbeing at ages 38 and 42 (N = 17,255, N = 16,703; born 1970), 50 and 55 (N = 12,775, N = 11,339; born 1958) and 63 (N = 2,364; born 1946), how sibling composition intersects with gender in relation to care-giving and whether different care-giving patterns are associated with wellbeing. Only children are more likely to provide parent-care and the pattern is consistent with an interpretation that differences by sibling status might increase with age. Provision is gendered, and the sibling group composition matters for involvement. Although care-giving is related to wellbeing, we found no evidence that this differs between only children and those with siblings. The literature on only children has hitherto focused largely on childhood, suggesting that on some outcomes they benefit from a concentration of parental resources. Our results suggest that in middle adulthood parental care needs may instead be concentrated for the only child without the ‘resource’ of siblings. This indicates a need to develop further our understanding of this growing demographic subgroup.

Differences in Power Acquisition Between Only and Non-only Children: The Effects of Cooperative Orientation, Competitive Orientation, and Dependency on Parents

Drawing upon a developmental perspective, we investigated the differences in power acquisition (i.e., rank at work and leader role occupancy in university) between only and non-only children as well as the mediating role of cooperative and competitive orientations and the moderating role of dependency on parents. To test our hypotheses, we conducted two field studies in 155 part-time Master of Business Administration (MBA) students (Study 1) and 375 senior students (Study 2). Results showed that: (1) non-only children were more likely to achieve higher rank at work than only children; (2) only children were less likely than non-only children to acquire power in organizations because they scored lower in cooperative orientation; however, the mediating effect of competitive orientation was not significant; (3) the difference in cooperative orientation between only and non-only children was smaller when dependency on parents was high, whereas it became larger when dependency on parents was low. Our research contributes to the understanding of how family structure influences individual power acquisition.

Birth order revelations about managers

Purpose

This paper aims to reveal the effects of birth order in decision-making style, conflict handling style and propensity for participative decision-making. The intention is to open the perspective of birth order research in organizational studies, as an important individual difference of managers.

Design/methodology/approach

A survey was conducted with 230 managers from different industries in Kosovo. Self-report measures were used for decision-making style, conflict handling style and participatory decision-making constructs.

Findings

Results indicate that only children are more avoidant and spontaneous decision-makers. Firstborns are rational in decision-making and prefer problem-solving in conflict handling. Middleborns are intuitive decision-makers and use compromising in conflict handling. Lastborns make decisions rationally and use both compromising and problem-solving in conflicting situations. In addition, lastborns appeared to have a more positive attitude toward participative decision-making, followed by middleborns, firstborns and only children.

Research limitations/implications

Birth order affects managers’ behaviors in decision-making and conflict situations. Relationship dynamics in sibships are reflected in organizational settings, affecting how people behave in decision-making and conflict handling.

Originality/value

To the best of the authors’ knowledge, this is the first study to attest how birth order influences the ways managers make decisions, handle conflicts and involve others in decision-making. As birth order cannot be changed, such knowledge is critical.

They Are Not Little Emperors: Only Children Are Just as Altruistic as Non-Only Children

Negative stereotypes about only children (OC) have caused widespread concern. However, relatively little is known about the accuracy of these stereotypes, especially regarding altruistic behaviors. In Study 1 ( N = 337), participants rated the altruism of OC and non-only children (NOC) on three measurements on the basis of the participants’ perceptions. Results revealed that participants rated OC as less altruistic, and the stereotype primarily came from NOC raters. Results of Study 2 ( N = 391) did not reveal any difference between OC and NOC in altruism. In Study 3 ( N = 99), a social discounting task was applied to further investigate whether OC and NOC displayed different degrees of altruistic behavior toward various social distances. No differences were found among individuals at close or distant social distances. Ultimately, this research indicates that the negative stereotype regarding the altruistic behavior of OC is an incorrect prejudice.

The role of only-child status in the psychological impact of COVID-19 on mental health of Chinese adolescents

BACKGROUND

The impact of coronavirus disease (COVID-19) on public mental health in 2019 is verified, but the role of only-child status in the mental health of adolescents confined at home during the COVID-19 epidemic has not been investigated and is not clear.

OBJECTIVE

Our study aims to assess the impact of only-child status on the mental health of adolescents confined at home during the COVID-19 outbreak. The exposure risk to COVID-19, adverse experience, parent-child relationship, and resilience have also been measured and considered.

METHODS

From March 20 to 31, 2020, a cross-sectional survey test was conducted on 11,681 adolescents aged from 12 to 18 years in middle schools (Grade 7 to Grade 9) across five provinces in China. The self-reported online questionnarie was used to collected data of demographic information, the 9-item Patient Health Questionnaire, the 7-item Generalized Anxiety Disorder Scale, the short form of the Childhood Trauma Questionnaire, the Connor-Davidson Resilience Scale and the exposure risk to COVID-19.

RESULTS

A total of 11,180 valid questionnaires were collected, with an effective rate of 95.7%. 35.2% of only children and 38.8% of non-only children reported depression symptoms, while 20.5% of only children and 24.7% of non-only children reported anxiety symptoms. It was significant that non-only children were more likely to have anxiety and depression symptoms than only children (OR = 1.164, 95%CI: 1.064-1.273, p = 0.001). The risk of exposure to COVID-19 was a risk factor of depression (OR = 2.284, 95%CI: 1.640-3.180, p < 0.001) and anxiety symptoms (OR = 1.959, 95%CI: 1.402-2.737, p < 0.001) in non-only children, but not in only children. For both only children and non-only children, the resilience and parent-child relationship were protective factors of depression and anxiety symptoms, while emotional abuse was a risk factor (p < 0.001).

CONCLUSION

The non-only children are more likely to develop the symptoms of anxiety and depression than only children, during the outbreak of COVID-19 in China. The adolescents with siblings are psychiatrically more vulnerable to exposure risk of COVID-19 and need more attention, especially those with poor parent-child relationship, low resilience and experience of emotional abuse.

Who Benefits From Being an Only Child? A Study of Parent-Child Relationship Among Chinese Junior High School Students

After more than three decades of implementation, China's one-child policy has generated a large number of only children. Although extensive research has documented the developmental outcomes of being an only child, research on the parent-child relational quality of the only child is somewhat limited. Using China Education Panel Survey (2014), this study examined whether the only child status was associated with parent-child relationships among Chinese junior high school students. It further explored whether children's gender moderated the association between the only child status and parent-child relationships. Two-level ordered logit models suggested that only children were more likely to report a close relationship with their mothers and fathers compared to children from multiple-child families (including two-child families). Taking birth order into consideration, we found that, only children were more likely to have close parent-child relationships than firstborns, whereas no significant differences were found between only children and lastborns. Interaction analyses further suggested that the only child advantages were gender-specific: the positive effects of the only child status were stronger for daughters than for sons, that is, daughters benefited more from being only children. Our findings highlight the importance of considering children's gender and birth order in exploring the only child effects in the Chinese context. Additional analyses about sibling-gender composition indicated female children were more likely to be disadvantaged with the presence of younger brothers, whereas male children benefited more from having older sisters. This reveals that the son preference culture is still deep-rooted in the Chinese multiple-child families.

Cultural patterns in autobiographical memory of childhood: Comparison of Chinese, Russian, and Uzbek samples

In the present study, I examined whether the regular patterns of variables that referred to mental representation of the entire childhood in young adults might be associated with the different types of cultural selves proposed by Kagitcibasi's model of family change. In this model, three types of cultural selves (heteronomous-related self, autonomous-separated self, and autonomous-related self) are merged with culturally specific styles of parenting and childhood experience. Chinese, Russian, and Uzbekistani participants (N = 439) visualized their childhood on timelines. The exploratory factor analysis suggested a three-factor solution. Factor 1 combined memories of achievements and vicarious memories; that is, memories representing events that happened to other people. In my point of view, in contrast to "we-memories," vicarious memories portray a readiness to view other people as a valuable part of one's own life, but in the context of well-defined self-boundaries. Therefore, they denote the kind of relatedness which does not contradict autonomy. Because Factor 1 was found to be the most articulated in the Chinese sample, it was linked to the autonomous-related self, with the focus on directive function of autobiographical memory. Factor 2 was composed of the abundance of recollections, the early age of first memory, and prolonged childhood. Due to the highest scores being achieved on Factor 2 in the Russian sample, it was attributed to the autonomous-separated self, employing predominantly a self-reflective function of autobiographical memory. Factor 3 consisted of memories of attending social groups, positive emotional bias, and a tendency to mention one's own birth. Taking into account that the Uzbeks achieved the highest scores on this factor, it was interpreted as a mnemonic database of a heteronomous-related self, predominantly associated with social bonding and emotion regulation functions. Taken together, the findings highlight the assumption that childhood memories reveal a cultural self.

The End of a Stereotype: Only Children Are Not More Narcissistic Than People With Siblings

The current research dealt with the stereotype that only children are more narcissistic than people with siblings. We first investigated the prevalence of this stereotype. In an online study (Study 1, N = 556), laypeople rated a typical only child and a typical person with siblings on narcissistic admiration and narcissistic rivalry, the two subdimensions of the Narcissistic Admiration and Rivalry Questionnaire. They ascribed both higher admiration and higher rivalry to the only child. We then tested the accuracy of this stereotype by analyzing data from a large and representative panel study (Study 2, N = 1,810). The scores of only children on the two narcissism dimensions did not exceed those of people with siblings, and this result held when major potentially confounding covariates were controlled for. Taken together, the results indicate that the stereotype that only children are narcissistic is prevalent but inaccurate.

The Prevalence of Only-Child Status Among Children and Adolescents Referred to a Gender Identity Service Versus a Clinical Comparison Group

Several studies indicate that homosexual males have a high proportion of older brothers compared to heterosexual males. Natal males with gender dysphoria who are likely to be homosexual also display this sibship pattern. Until recently, there was little evidence linking homosexuality and/or gender dysphoria in females to unique sibship characteristics. Two studies have indicated that natal female youth clinically referred for gender dysphoria are more likely to be only children (Schagen, Delemarre-van de Waal, Blanchard, & Cohen-Kettenis, 2012; VanderLaan, Blanchard, Wood, & Zucker, 2014). However, these studies did not include control groups of youth clinically referred for other reasons. Thus, it is unclear whether the increased likelihood of only-child status is specific to gender-referred natal females. This study compared only-child status among youth referred to a mental health service for gender dysphoria (778 males, 245 females) versus other reasons (783 males, 281 females). Prehomosexual gender-referred males were less likely to be only children than clinical controls. Contrary to previous findings, gender-referred females were not more likely to be only children, indicating that increased likelihood of only-child status is not specific to gender-referred females, but is characteristic of clinic-referred females more generally.

[The mental health of only children and of siblings with cancer - first results of a multicenter study in Germany]

BACKGROUND

Children of parents with cancer are at risk of developing mental disorders. RESULTS from divorce research also reveal that sibling relationships can protect the mental health of children in difficult times.

OBJECTIVE

Does having a sibling help to cope with an oncological disease of a parent and thus act as a protective factor?

METHODS

A group of 271 children were examined in a multicenter study. 54 % made use of the offered psychosocial support. Only children (N = 89) and children with siblings (N = 182) were compared with respect to their mental health (Strength and Difficulties Questionnaire, SDQ, parental and self-assessment).

RESULTS

The group comparison between only children and siblings showed no significant differences in the SDQ (assessed by healthy/ill parent). In the self-assessment 2 % of the only children and 9 % of the siblings showed significant results on the SDQ. The group comparison between only children and children with siblings failed to reveal any important differences in mental health. The study indicates that a negative relationship quality (Sibling Relationship Questionnaire, SRQ) is associated with increased problems in the peer group.

CONCLUSIONS

The existence of a sibling is not per se a protective factor. Only children do not show more signs of emotional stress than children with siblings.

Predictors of immigrant children's mental health in Canada: selection, settlement contingencies, culture, or all of the above?

BACKGROUND AND STUDY AIMS

A previous publication from the New Canadian Children and Youth Study, a national study of immigrant children and youth in Canada, showed a gradient of levels of emotional distress with children from Hong Kong (HK) at the most severe end, Filipino children at the least severe, and children from the People's Republic of China (PRC) in between. Based on the premise that country of origin can be regarded as an index for differing immigration trajectories, the current study examines the extent to which arrival characteristics, resettlement contingencies and cultural factors account for country of origin variations in immigrant children's mental health. Arrival characteristics included child's age at arrival, parental education, parental fluency in English or French, and assistance from family at arrival. Resettlement contingencies included parental mental health, intra-familial conflict, settlement stress, separations from parents and child's age when mother started working outside the home. Cultural factors included one-child family composition and parenting styles.

METHODS

A national survey of 2,031 families with at least one child between the ages of 4 and 6 or 11 and 13 from HK, the PRC and the Philippines was conducted with the Person Most Knowledgeable (PMK) in snowball-generated samples in 6 different cities across Canada. Predictors of the dependent variable, emotional problems (EP), were examined in a hierarchical block regression analysis. EP was regressed on ethnic and country of origin group in model 1; arrival characteristics were added in model 2; resettlement contingencies in model 3 and cultural factors in model 4.

RESULTS

The final set of predictor variables accounted for 19.3 % of the variance in EP scores among the younger cohort and 23.2 % in the older. Parental human and social capital variables accounted for only a small amount of the overall variance in EP, but there were statistically significant inverse relationships between EP and PMK fluency in English or French. Settlement contingencies accounted for a significant increase in the explanatory power of the regression equation, net of the effects of country of origin and selection characteristics. This block of variables also accounted for the Filipino mental health advantage. Levels of parent's depression and somatization, harsh parenting, intrafamilial conflict, and resettlement stress each varied directly with levels of children's EP. Cultural variables made a significant contribution to explaining the variance in EP scores. Harsh parenting was significantly associated with increased levels of EP in both age groups, and supportive parenting was a mental health protective factor for younger children.

CONCLUSIONS

Immigrant family human and social capital, according to which immigrants are selected for admission to Canada, play a relatively small role in determining children's mental health. These effects are overshadowed by resettlement contingencies and cultural influences. Concentrating on trying to find a formula to select the "right" immigrants while neglecting settlement and culture is likely to pay limited dividends for ensuring the mental health of children.

Comparing Adolescent Only Children with Those Who Have Siblings on Academic Related Outcomes and Psychosocial Adjustment

This study uses a large and representative sample of adolescents to test the theoretically informed hypotheses comparing adolescent singletons with those who have siblings. The results found that, for academic related outcomes (educational expectations, time spent on homework, and self-reported grades), there are no differences between singletons and firstborns who have any number of younger siblings. Singletons are also not different from laterborns from two-child families. In contrast, singletons are more advantageous compared to laterborns who have two or more siblings on educational expectations and grades. Singletons also spend more time on homework than laterborns who have three or more siblings. For psychosocial outcomes (psychological distress, susceptibility to negative peer pressure, and problem behaviors), singletons are not different from both firstborns and laterborns with any number of siblings. The findings suggest that singletons are not at any disadvantage compared to their peers who have siblings and they enjoy some advantages over laterborns from medium to large families on academic related outcomes.

Práticas educativas parentais em relação ao filho único e ao primogênito

O objetivo deste estudo foi examinar eventuais diferenças das práticas educativas parentais em relação a filhos únicos e primogênitos de famílias com dois filhos. Participaram 12 famílias com filho único e 10 com dois filhos, emparelhadas conforme o nível socioeconômico, idade e gênero das crianças. A idade dos filhos únicos variou entre 4,6 e 6,1 anos (M=5,5, DP=0,51) e a dos primogênitos entre 4,3 e 6,3 anos (M=5,1, DP=0,78). Mães e pais dos dois grupos responderam a uma entrevista sobre práticas educativas parentais, cujas respostas foram submetidas à análise de conteúdo. O teste do qui-quadrado revelou diferença marginalmente significativa somente nas práticas maternas e paternas em relação ao filho único. Verificou-se semelhança nas práticas educativas entre mães e pais em ambos os grupos. Os resultados foram discutidos à luz da literatura, buscando entender os fatores que podem contribuir para explicar semelhanças das práticas educativas utilizadas para filhos únicos e primogênitos.

School performance, peer association, psychological and behavioral adjustments: a comparison between Chinese adolescents with and without siblings

We test theoretically informed hypotheses using survey reports of adolescents attending three middle schools in the outskirts of Fuzhou, Fujian, China. Results yielded by regression analyses are quite consistent with the hypothesized relationships, that is, Chinese singleton adolescents are more likely to anticipate going to college than non-singleton adolescents. Further, singletons are more associated with conventional peers and they report better adjustments both psychologically and behaviorally than non-singleton adolescents. Singletons and non-singletons, however, are not different in their self-reported performance in four school subjects, namely, Chinese, Math, English, and Political Studies. These results are discussed in light of the theoretical literature, especially related to attachment theory, resource dilution theory as well as confluence model.
