The Influence of Siblings on Young Children’s Understanding of Fluid Intake

Background Children need to drink enough water (1.1-1.3 litres) throughout the day to stay hydrated and for health benefits1. Wellbeing and cognitive function benefits have been identified for children who are hydrated2. Yet there is a dearth of research focusing specifically on children’s perceptions of their own fluid intake levels and who helps support them in ensuring they are drinking enough water, this is a novel area to investigate. Previous research3 identified that 44.2% of young children’s fluid intake were influenced the strongest by a family member. This paper will explore in further detail the influence of siblings on children’s fluid intake, in particular older versus younger siblings. Methods 130 children (67 girls and 63 boys, of which 45 had a younger sibling (s) and 85 having an elder sibling(s), from 4 primary schools in the South East of England, were questioned between January and April 2019 using an adapted version of Coppinger and Howells’ (2019)4 questionnaire, on their understanding of fluid intake, how much they perceived they drank and who supported them in prompting them to drink. Physical visual representations were used to aid question comprehension and to ensure the questions were appropriate for young children. The data was analysed using SPSS 24.0 using MANOVAs (P < 0.05) to consider statistical variance in gender and older sibling status. Results The most significant results were linked to elder siblings influence younger siblings in drinking too little fluids within a school day (F=0.530, p<0.05), whilst those without an elder sibling, thought they drank beyond the daily recommended guidelines and reported they drank over 2 litres. This illustrates that children misunderstand fluid intake recommendations regardless of whether they have an elder sibling or not. Children named adults, both parents and teachers as well as elder siblings as the key influencers of them drinking (F=3.67, p<0.05) and the data indicated that girls were more influenced by siblings than boys, whilst twins were not influenced by each other. Conclusion It is concluded that siblings do have an influence on the consumption of water, as siblings act as role models and other siblings follow their habits, therefore the whole family unit is important to ensure that the right fluid intake is consumed. It is recommended that further education, curriculum and community development is needed to continue to support young children’s knowledge and understanding of fluid intake.

A replication study of JTC bias, genetic liability for psychosis and delusional ideation

Background This study attempted to replicate whether a bias in probabilistic reasoning, or ‘jumping to conclusions’(JTC) bias is associated with being a sibling of a patient with schizophrenia spectrum disorder; and if so, whether this association is contingent on subthreshold delusional ideation. Methods Data were derived from the EUGEI project, a 25-centre, 15-country effort to study psychosis spectrum disorder. The current analyses included 1261 patients with schizophrenia spectrum disorder, 1282 siblings of patients and 1525 healthy comparison subjects, recruited in Spain (five centres), Turkey (three centres) and Serbia (one centre). The beads task was used to assess JTC bias. Lifetime experience of delusional ideation and hallucinatory experiences was assessed using the Community Assessment of Psychic Experiences. General cognitive abilities were taken into account in the analyses. Results JTC bias was positively associated not only with patient status but also with sibling status [adjusted relative risk (aRR) ratio : 4.23 CI 95% 3.46–5.17 for siblings and aRR: 5.07 CI 95% 4.13–6.23 for patients]. The association between JTC bias and sibling status was stronger in those with higher levels of delusional ideation (aRR interaction in siblings: 3.77 CI 95% 1.67–8.51, and in patients: 2.15 CI 95% 0.94–4.92). The association between JTC bias and sibling status was not stronger in those with higher levels of hallucinatory experiences. Conclusions These findings replicate earlier findings that JTC bias is associated with familial liability for psychosis and that this is contingent on the degree of delusional ideation but not hallucinations.

Genesis of Psychological Sovereignty: Birth Order Factor

The ability to defend the boundaries of one’s empirical self — dispositional sovereignty — is a personality trait with a great adaptive value. It develops through the generalization of everyday actions aimed at protecting the boundaries in discrete situations with other people, first, with one’s family. This paper explores the role of sibling status (birth order) in the development of this trait. Two empirical studies were conducted. In the first of them, carried out with the participation of children aged from two to ten, it is shown that the most mature ways of protection are for only children in the family, the least mature are the first children, and the second children in the family demonstrate an intermediate level of development of boundary protection skills. In the second study conducted on the youth sample, it is shown that the relationship between sovereignty and the order of birth depends on gender: sovereignty hits its peak among younger girls and older boys.

Adolescent Girls’ Disclosure About Dating and Sexuality

Adolescents disclose information about romantic relationships and sexuality to family members and friends, but little is known about the correlates of this disclosure. We examined adolescent girls’ ( N = 68; 34 sister dyads) choice of disclosure partner regarding thoughts/concerns about dating and sexuality. Adolescents were more likely to choose mothers and sisters (compared with friends) as disclosure partners regarding dating and sexuality topics. Using multilevel modeling, we also examined romantic relationship and sexual correlates of disclosure partner selection. Adolescents’ disclosure to mothers and sisters was associated with positive relationships. We also found that adolescents who selected mothers as disclosure partners for sexuality reported greater romantic relationship intimacy and adolescents who selected friends as disclosure partners for sexuality reported less conservative sexual attitudes than other adolescents. Furthermore, our findings revealed that adolescents’ choice of disclosure partner was associated with their sexual attitudes, and these associations differed by topic and sibling status.

The Process Density Index as a Measure of Phonological Development: Data From Dutch

The Process Density Index (PDI), originally developed by Edwards, is a potentially useful metric for assessing phonological development that is based on the average number of phonological process applications per word in a speech sample. The purpose of the present study was to gather PDI reference data for Dutch-speaking children. Speech samples were collected and the PDI values were determined in 120 Dutch-speaking children aged between 2;6 and 5;6 years of both genders. Boys showed a higher PDI than girls, and there was a strong negative relationship between age and PDI. The presence of a history of otitis media, socioeconomic status, and sibling status, however, were of no influence. The results confirm trends seen in previous studies on phonological development of typically developing children using other metrics. This suggests that the PDI is a valid measure to assess phonological acquisition.
