Research Question
Twins, Adoptees, Peers, and Sibling (TAPS) Study.
University of San Francisco and California State
University, Fullerton.Funded by: The National Institute of
Mental Health (R01 MH63351)
 Participants were 207 sibling and twin
pairs, aged 7 to 13, who participated in
the Twins, Adoptees, Peers, and
Siblings (TAPS) Study.
 The families were predominantly middle
class, with 63% of European ancestry.
 The children were interviewed about
their family relationships by trained
testers as part of a three-hour home
interview.
 Pairs with children who experienced
birth difficulties that may affect
behavioral development were excluded.
 Joint decision-making:
Sibling and twin pairs were videotaped
and asked to work together to
complete a puzzle task. Independent
coders recorded the total time spent
completing the puzzle. Puzzle task
inter-rater reliability was 0.98.
Children were split into two groups:
164 pairs completed the task on time
and 42 were unable to complete it
within the 3-minute time limit.
 Relationship Quality:
Children were interviewed about
sibling intimacy (α = .81), conflict (α = .
92), trust (α = .84) by a trained tester.
Pairs who completed the task were higher
in sibling intimacy (M = 26.7) compared to
pairs who did not (M = 25.8; t(1) = -0.83,
n.s.).
Pairs who completed the task were similar
in sibling trust (M = 33.5) compared to pairs
who did not (M = 33.4; t(1) = -1.23, n.s.),
but lower in sibling conflict (M = 16.4)
compared to pairs who did not (M = 17.2;
t(1) = 0.76, n.s.).
While means were in the expected
direction, they were not significantly
different from each other.
 Positive sibling interactions may promote
the development of prosocial skills in
children (Stormshak et al., 1996).
 Previous research has demonstrated
that reciprocal sibling interactions are
positively associated with warmth,
mutual esteem, happy daily exchanges,
and negatively related to rivalry and
dominance in different-aged sibling pairs
(Karos et al., 2007).
 Research also suggests that having a
supportive, cooperative sibling
relationship in childhood helps children
navigate stressful circumstances, such
as parental divorce (McGuire &
Shanahan, 2010).
 The purpose of the current study was to
examine a key aspect of a mutual sibling
relationships, joint decision-making.
 Examining correlates of how well siblings
solve problems during the middle
childhood years could contribute to our
understanding of how well they will work
together in future stressful
circumstances, such as caring for a sick
parent (Ingersoll-Dayton, Neal, Ha, &
Hammer, 2003).

of social competence and behavioral control in aggressive
children. Developmental Psychology, 32(1), 79.
The study focused on the research
question: Is joint decision-making in
school-aged sibling pairs linked to
children’s reports of sibling conflict,
trust, and intimacy?
Sibilng Relationship Quality
 The hypothesis that completing a
decision-making task would be linked to
sibling relationship quality was not
supported in this sample of school-aged
siblings and twins.
 Several factors could be contributing to
the lack of significant results, including
the the reliance on sibling report of
relationship quality.
 In addition, the sample size may not
have been large enough and the
measure of decision-making may not
have been sensitive enough to detect
subtle effects.
 Future analyses will include examining
parent reports of sibling relationship
quality and the role of structural variables
in predicting group differences.
