AUTHOR=Shi Xinxin , Campione-Barr Nicole TITLE=The Effects of Parenting and Temperament Similarity Among Adolescent Siblings on Positive Family Relationships JOURNAL=Frontiers in Psychology VOLUME=Volume 12 - 2021 YEAR=2021 URL=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.702000 DOI=10.3389/fpsyg.2021.702000 ISSN=1664-1078 ABSTRACT=The detrimental effects of parental differential treatment have been shown in previous research (Coldwell, Pike, & Dunn, 2008), but fewer researchers have pointed out that differential treatment does not always lead to negative outcomes (Kowal & Kramer (1997). Thus, the present study examines the role of temperament similarity on the association between parenting similarity and positive family relationship qualities over 1 year in 145 adolescent sibling dyads (Mfirst-born = 14.97, SD = 1.68 years; Msecond-born = 12.20, SD = 1.92 years). Latent moderator structure models (LMS) showed that higher level of parenting similarity was related to more positive family relationships when siblings were more similar in their temperaments; however, lower level of parenting similarity was related to more positive relationship qualities with family members one year later in the context of less sibling temperament similarity.
