This article focuses on associations between sibling relationships and children’s conduct problems based on cross-lagged models. Using a large, population-based sampling frame Pike examine longitudinal links between positive and negative aspects of sibling relationships and children’s prosocial behavior and conducted problems. The children’s ages ranged from four to twelve years. Pike and Oliver focused on conducting problems since it is the best way to predict diverse mental health problems in adulthood and prosocial behavior, which then determines the long-term education, criminal outcomes, and employment. Pike and Oliver hypothesized that the temporal flow of influence would be bidirectional. Questionnaires were sent to 12,349 mothers and were returned by 9,501 when the target was four years old. When the target was seven years old, questionnaires were sent out to 10,662 mothers, 8,505 returned. This study revealed that sibling relationship positivity was more highly correlated with prosocial behavior, whereas negativity was more associated with conduct problems. This article is important since it provides evidence for bidirectionality, which is good news for clinical applications. Killoren, S. E., Jesus, S. A., Updegraff, K. A., & Wheeler, L. A. (2016). Sibling relationships quality and Mexican-origin adolescents´ and young adults´ familism values and adjustment. International Journal of Behavioral Development, 41(2), 155-164. doi:10,1177/0165025415607084This article focuses on the profiles of sibling relationship qualities in 246 Mexican origin families living in the United States by using a latent profile analysis. In this study there were three profiles identified, the positive profile, the negative profile, and the affect-intense profile. Longitudinal data was also used in this study to link profiles and youth´s familism values. Based on the data, siblings in the positive profile reported the highest familism values, followed by the siblings in the affect-intense profile and the profile with the lowest familism values were the siblings in the negative profile. This study revealed that older siblings in the positive and negative profiles reported less involvement in risky behaviors than younger siblings. Older siblings in the positive and affect-intense profiles reported fewer depression signs than siblings in the negative profile. Younger siblings in the negative profile reported greater sexual risk behavior in late adolescence than older siblings. In the positive profile older and younger siblings tend to have a better quality relationship than sibling in affect-intense and negative profiles. This study revealed sibling relationship quality as encouraging and risky, depending on sibling relationship profiles. Howe, N., Della Porta, S., Tecchia, H., & Ross, H. (2016). ´Because if you don’t put the top on, it will spill´: A longitudinal study of sibling teaching in early childhood. Developmental Psychology, 52(11), 1832-1842. doi:10.1037/dev0000193The purpose of this study was to investigate sibling teaching frequency, teaching strategies, and learning involvement during early childhood, starting when the siblings were ages two and four years (during the first study) and four and six years (during the second study). The controlled variable in this study was the teacher´s age, learners were either two year old younger or six year old older siblings, which allowed the researchers to examine the influence of important learner characteristics on the nature of sibling teaching. At each time point, 40 middle-class Caucasian families were observed for six 90-minute sessions at home for a total of nine hours per family. The first part of the study compared older and younger sibling teaching across time points and in the second study they did a cross-sectional comparison of the four year olds´ teaching and learner responses. This article is important because it provides insights into the developmental trajectory of sibling teaching in early childhood. Kretschmer, T., & Pike, A. (2010). Associations between adolescent siblings relationships quality and similarity and differences in values. Journal of Family Psychology, 24(4), 411-418. doi:10.1037/a0020060The purpose of this study was to explore the correlations between the quality of sibling relationships and their self-perceived values. Kretschmer and Pike predicted that a good relationship would have a positive effect on intrinsic values, like compassion and diversity, while having a negative effect on extrinsic values, like power and materialism. Going along with that, a bad relationship between siblings would have a positive effect on extrinsic values while negatively affecting intrinsic values. A study was conducted with 205 adolescent sibling pairs, each sibling was asked to complete questionnaires relating to their personal values and their relationship with their sibling(s). This study revealed that siblings are likely to share the same values much more than between parent and child. Sibling competition leads to high levels of interaction between the siblings, leading to the development of the same values. While siblings in a non-competitive environment had a greater intrinsic values with those in highly competitive environments had increase extrinsic values. Örücü, M. %., & Er, S. (2017). Communication satisfaction and trust among Turkish adolescent siblings. Social Behavior and Personality: an international journal, 45(1), 143-153. doi:10.2223/sbp.5664This article focuses on the impact of gender and age difference on sibling relationship communication satisfaction and trust experience by Turkish adolescents. The researchers predicted that same-gender sibling dyads would have a higher communications satisfaction and dyadic trust compared to mixed-gender sibling dyads. The researchers also predicted that siblings who have an age difference that is greater than five years will have greater communication satisfactions and dyadic trust compared to those with less of an age difference. Correlational research was used to examine the relationships among variables without any attempt to influence those relationships. Participants were recruited through purposive sampling. Females had more satisfaction in their communication with their siblings than males did. This study also showed that females had more trust in their relationships with their siblings than male students did. This studies revealed that age difference did not affect siblings´ relationships in terms of trust and communication satisfaction. This study was not nationally representative; therefore, the finding should be replicated using more diverse samples.
