We had 18 eggs artificially hatched in a mass breeding place of black-tailed gulls and examined the individual recognition between young siblings in a laboratory environment. The results of the experiment showed that the young gulls selectively responded to their siblings and non-siblings at an early stage after hatching. It was shown that they began to recognize the begging call among the voice signals of siblings and non-siblings 15-16 days after hatching, and the chirirah call 11-12 days after hatching. Also, more significant results were shown with the chirirah call than with the begging call. In an experiment of visual recognition between siblings and non-siblings, the young black-tailed gulls approached their siblings significantly 9-10 days after hatching. The recognition between young siblings in a mass breeding place provides an important evolutionary indicator in terms of their social behaviors.

The sample of this study on sibling relationships consisted of 40 pairs of preschool siblings and their mothers. Results were that elder siblings initiated more behavior, initiated more negative behavior, and responded with more negative or no response to affirmative behavior initiated by the younger siblings. Younger siblings exhibited more responsive behavior, initiated more affirmative behavior, showed more affirmative responses to or imitation of affirmative behavior, and imitation of negative behavior than elder siblings. Male pairs exhibited more physical affirmative interaction than female or male-female pairs. Female pairs exhibited more lingual affirmative interaction than male or male-female pairs. Siblings with similar temperaments showed more boastful or no response to negative behaviors than siblings with differing temperaments. Siblings with differing temperaments exhibited more affirmative behaviors than siblings with similar temperaments.

Purpose: This study was conducted to define the concept of stress in siblings of childhood cancer patients. Methods: The hybrid model was used to perform the concept analysis of stress in childhood cancer patients' siblings. Through reviews of 16 studies in the theoretical phase and interviews with 20 siblings in the field phase, the derived results were brought together in the integration phase. Results: The concept of stress in siblings of patients with childhood cancer was found to have 6 attributes and 28 indicators in 3 domains. Personal factors included 2 attributes (fear about childhood cancer and immature coping skills), and family factors had 2 attributes (changes in relationships with family and changes in family environment), social factors had 2 attributes (changes in relationships with friends and in the school experience, and insufficient social support). Conclusion: The stress of siblings of childhood cancer patients was defined as a state of tension associated with personal, family, social factors that can be related to their siblings' childhood cancer. The findings in this study provide the base for the development of a tool for measuring siblings' stress and/or the development of nursing programs for these siblings.

This study attempted to analyze the psychological impact of mentally retarded children on their normal siblings in the family. The data were collected from siblings of 130 mentally retarded children using a questionnaire with a semantic differential scale. ANOVA and simple correlation coefficient tests were employed to examine the relationship between the siblings’ self-concept and psychological frustration. The major results of the study are as following. 1. Female siblings showed a lower degree of self-concept than male siblings. 2. No significant relationship was found between self-concept and frustration stimuli. 3. Parent related frustration stimuli was no significantly different in sex age, siblings, religion, and retardation level of mentally retarded children. 4. Siblings related frustration stimuli was significantly related to only one item in sex. 5. Their peers related frustration stimuli while sex as well as religion was significantly related to only one item.

We examined play interactions between siblings when one child has autism in a Vietnamese American and a European American family. Analysis was based on video recorded free play sessions with each set of siblings at their home. Interviews with the typically developing sibling and parents also provided supplemental data to aid our knowledge about their play behavior. This study describes the role of the typically developing sibling in play and the types of play engaged in by siblings. Findings indicate that the two sets of siblings differed in their play behavior. Specifically, significant differences were noted in the role of the typically developing sibling in play, and the types of play engaged in by the siblings. The perceptions of the typically developing siblings and parents regarding autism also differed across families, significantly affecting their play behavior. Implications for research are described.

In this study, it is explored whether teasing from parents and siblings about appearance of children affects body satisfaction and self-esteem of middle school students. A total of 594 adolescents participated in the survey and the causal model was tested with the data. In results, parents' and siblings' teasing was significantly correlated. Parents' and siblings' teasing significantly affected body satisfaction that showed a significant impact on self-esteem. In the mean comparison by gender, female adolescents suffered more from parents' as well as siblings' teasing on appearance than did male adolescents. Female adolescents indicated lower body satisfaction than male adolescents whereas no gender difference was found in self-esteem. In the multiple-model comparison, both the parents' and siblings' teasing about appearance affected body satisfaction of female adolescents while only siblings' teasing affected body satisfaction of male adolescents. The results indicate that female adolescents are more likely to be exposed to parents' and siblings' teasing about appearance at home than male adolescents, resulting in negative body satisfaction that is influencing self-esteem. The finding could be used as a basis for family education, calling for an attention to this issue.

The purpose of this study is to review Korean literature concerning sibling relationships during the last three decades and investigate facts and trends, research issues, and pragmatic and policy issues related to sibling relationship development. Most of the past research has been concerned with the effects of sibling status/structure variables on siblings' individual differences in intellectual, social and personality characteristics. In recent years, however, considerable attention has been focused on the interpersonal relationships between siblings and the factors influencing such relationships. More specifically, sibling relationships and adjustment of siblings of children with disabilities begin to draw attention of researchers and practitioners. This review consists mainly of two parts : one on siblings of children with no disabilities and the other on siblings with one disabled child.

The purpose of this research is to study differences in perceived parental neglectful behaviors between siblings from a child's perspective. The data were collected using the Multidimensional Neglectful Behavior Scales (MNBS) questionnaire from 158 sibling pairs in grades 4, 5, and 6 who attended the same elementary schools. Younger sibling experienced emotional neglect by their parents significantly more than older siblings. Same gender sibling pairs and older brotheryounger sister pairs perceived their parental neglectful behaviors in a similar manner. However older sister-younger brother pairs showed that the younger brother perceived significantly more neglect than his older sister. This study clearly illustrated that siblings' perceptions of their parents' neglectful behaviors exists differently within a family contrary to previous studies which have shown that siblings' perception of parental neglectful behaviors are similar. The results suggest that the younger brother in mixed-gender sibling pairs are far more likely to experience neglect than any other sibling. Thus, even though siblings can be at equal risk in experiencing parental neglect, the effects can vary depending on the birth order.

Purpose: This study investigated the association between sleep problems and food allergies (FAs) in Chinese preschoolers and assessed whether there is a difference in this association among children with/without siblings. Methods: A cluster-stratified sampling approach was employed to select four districts in Chongqing based on demographic considerations. A total of 16 kindergartens (n = 966 parents) participated in this study. Parents completed the Children's Sleep Habits Questionnaire (CSHQ) and a standard FAs questionnaire. Analysis of covariance and multiple logistic regression were used to assess the associations between sleep problems and FAs after adjusting for relevant confounders. Results: The study found that 16.3% of children had FAs, with eggs, shellfish, and fruit being the most common allergenic foods. The prevalence of FAs was significantly higher in single children (20.63%) than in children with siblings (13.36%). A total of 70.39% of children had CSHQ scores above the clinical cut-off for sleep disorder. Factor analysis revealed five underlying dimensions from the CSHQ. Factor scores, except for the 'difficulty morning waking' factor, were not significantly different between the two groups. Remarkably, the factor scores of 'parasomnias' and 'sleep anxiety' were significantly higher when children had both siblings and FAs. For all subjects, the odds ratios (ORs) of FAs significantly increased with the presence of sleep disorder (OR, 2.35; 95% confidence interval [CI],1.50-3.68) and 'difficulty falling asleep' (OR, 1.34; 95% CI, 1.22-1.48). The subgroup analysis showed that the probability of FAs significantly increased with the 'difficulty falling asleep' (OR, 1.32 vs. 1.38) and sleep disorder (OR, 2.48 vs. 2.14) in children with and without siblings, respectively. The 'parasomnias' was positively associated only with children with siblings. Conclusion: This study suggests that children with siblings might be more susceptible to FAs when accompanied by certain sleep problems. Further studies are warranted to address the underlying dimensions and possible mediation effects of having siblings with sleep problems.

The factors that affect the adjustment of the siblings of handicapped children were explored in this study. More specifically, how social and demographic variables affect the burdens the handicapped children's siblings experience, and how such burdens affect their adjustment in school and in the family were examined. The participants of this research were 139 students in elementary schools and middle schools, who have one or more handicapped siblings. The participants were recruited through their handicapped siblings who received services from social wet(are facilities in Daejon and Chungchong area. The scales used in this study were the measurement or Burdens for Handicapped children's siblings (Lee, Yoon Hwa, 2002), FACES (Olson et al, 1986). and The Measurement of Children's Adjustment in the School (Lim Jung Soon, 1993). The data were analyzed by frequency, percentage, average. standard deviation, T-test, one-way ANOVA, and multiple linear regression. 'rho results show that handicapped children's siblings have no difficulty in adjusting in the family if they have a religion, an elderly mother, and a high family income. They have no difficulty in adjusting in the family and in school, as long as they have no or little negative change in family relationship, low psychological burden, and no negative relational change for the handicapped sibling. Father's age and the family income their the only factors that affect their adjustment in school.
