The predictors of parental differential treatment and dyadic relations with sibling attachment

Gülaçtı, Huri Gül Bayram
The main purposes of the present dissertation are to develop a reliable and valid scale to assess maternal differential treatment (MDT), to investigate structural (gender constellation and composition), individual (negative affect and perceptual sensitivity), and maternal (familism and traditional and modern approaches in parenting) factors associated with absolute MDT as well as to examine the dyadic relationship between relative MDT and sibling attachment. For these purposes, two studies were conducted. In Study I, Sibling Perceptions of Differential Parental Treatment Scale-Mother Form (N = 351) was developed. Two main factors were obtained: MDT in positive and negative domains and further analyses supported two-factor solution (attentiveness and pampering/indulgence) for positive domains and three-factor solution (punishment, negative discipline, negative affect/rejection) for negative domains, separately. The scale had good psychometric properties. In Study II, the main hypotheses were tested with the participation of 356 older and younger siblings and their mothers. The siblings completed MDT, temperament, and sibling attachment scales, and mothers completed familism values and approaches in parenting scales. The results indicated that MDT did not differ based on gender constellation. v Hierarchical regression analyses showed that MDT was clearly predicted by temperament but not by other factors. Dyadic relations between MDT and sibling attachment was tested with Actor-Partner Interdependence Model analyses. The findings suggested that after controlling for siblings’ gender, most of the actor and one partner effect were associated with sibling attachment. The current study contributed to the literature by examining the mechanisms and outcomes of MDT in Turkish culture.


The Relationship between parent-child characteristics and child outcomes: mediator role of emotion-related socialization behaviors
Gölcük, Merve; Kazak Berument, Sibel; Department of Psychology (2020)
The purpose of the current study was to investigate the mediator role of emotion-related socialization behaviors (supportive and non-supportive reactions) in the relationships between child temperamental characteristics (anger/frustration and perceptual sensitivity), maternal personality traits (Agreeableness and Openness-to- experience), maternal autonomous-related self-construal and the child outcomes of emotion regulation and theory of mind. In addition, the study aimed to examine the cross-lagged relati...
The Effect of maternal parentification history, maternal attachment styles, socioeconomic status and children’s self-construals on parentification roles and perceived parental caregiving
Karagöbek, Ayşe Büşra; Şahin Acar, Başak; Department of Psychology (2014)
This thesis study aimed to explore how well the maternal history of parentification, adult attachment styles, self-construal of children and SES of the family contribute to explain the variability on parentification behaviors of children. The sample comprised 92 mother-child dyads. Mothers’ mean age was 40.11 (SD = 5.56), and mean education level of 2.45 (SD = 1.25). Children’s mean age was 12.56 (SD = .63). Mothers were given the Filial Responsibility Scale- Adult Version (Jurkovic, Thirkield, and Morrell,...
The mediator role of parenting behaviors on the relationship between parenting beliefs and internalization of rules: Moderator role of gender and temperament
Koç Arık , Gizem; Kazak Berument, Sibel; Department of Psychology (2021-10)
The aim of the present study was to examine the mediator role of parenting behaviors (positive and negative) in the relationships between parenting beliefs and the internalization of rules among children or adolescents. Also, the study aimed to test the moderator role of temperament (frustration and sensory processing sensitivity) in the association between parenting behaviors and the internalization of rules. Lastly, the study aimed to test whether the proposed relationships differ among girls and boys. In...
The association between parenting practices and peer rejection, moderated by sensory processing sensitivity of the child
Anaçali, Elif; Kazak Berument, Sibel; Department of Psychology (2023-1)
The current study aims to investigate the relationships between parenting dimensions (acceptance, behavioral and psychological control) and peer rejection of children and adolescents from 5th to 11th grade (Nfemale = 1741, Nmale = 1435), moderated by child’s sensory processing sensitivity (depth of processing and overreaction to stimuli). In order to explore gender interactions, separate path models for mother-daughter, mother-son, father-daughter, and father-son dyads are tested. Gender differences between...
