Adolescents' Sibling Relationships: Conflict, Equity and Satisfaction

Paper presented at 5th Australian Family Research Conference:
Brisbane, November 1996



During adolescence, sibling relationships acquire special significance. The need to become emotionally independent of parents may lead adolescents to turn to their siblings for advice, solidarity and emotional support. At the same time, the increased interpersonal conflict that is apt to arise in families as offspring pass through puberty can intensify processes of sibling rivalry, quarrelling and competition. Furthermore, the quality of the relationship that siblings establish with one another during adolescence has the potential to bring them together, or draw them apart, throughout the remainder of adult life. This study explored late adolescents' satisfaction with their sibling relationships as a function of age, gender and the dynamics of their interaction with one another. The specific aspects of interaction we examined included the following: (a) patterns of global equity and satisfaction in the sibling relationship, {b) frequency and topics of disagreement between siblings, and (c) the strategies used to resolve conflict in the sibling dyed. The sample consisted of 222 Australian adolescents aged 16 to 19 years with a sibling no more than 4 years younger or older than themselves. Other sample characteristics appear in Table 1.

Questionnaire Measures

Respondents completed questionnaire booklets containing the following scales: (a) Hatfield et al.'s (1990) Global Measure ( an index of relationship equity requiring respondents to rate their 'relationship as a total package' on a 9-point scale; sample item: 'I get a very much better deal than my sibling'), (b) an
adaptation for siblings of Norton's (1983) Quality Marriage Index (QMI), (c) Argyle and Furnham 's (1983) measure of the topics and intensity of siblings' common disagreements, and (d) a conflict resolution measure that was developed for the present study on the basis of Rands et al.'s (1981) marital measure, and is illustrated in Table 2.

RESULTS AND DISCUSSION

Equity versus exploitation

The results indicated a dichotomy in the sample between strictly equitable (52 percent) and imbalanced sibling relationships. Out of the total (48 percent) who perceived their relationship with their closest sibling as inequitable, 52 percent (or 2596 of the total sample) felt exploited by their sibling (dubbed 'underbenefit' ) and 48 percent (23 % of the total) felt they gained too much (dubbed overbenefit). The external validity of these subjective impressions was indicated by the significant agreement we observed between the pairs of siblings from the same family as to both the degree and the direction of the inequalities arising between them. In contrast to previous research (Peterson et al. ,1994), no differences in equity patterns emerged as a function of siblings gender, the gender match of the dyad or birth order (see Table 3).

Equity and Relationship Satisfaction

There was no statistically significant difference due to gender in the amount of satisfaction respondents derived from their sibling relationship. Male and female groups were therefore combined for the analysis of the relationship between equity and satisfaction. According to Equity Theory ( Hatfield et al., 1979), both underbenefit (to a large extent) and overbenefit (to a lesser extent) serve to undermine satisfaction with an intimate relationship, relative to the experience of strictly equitable fairness. Table 4 shows the mean levels of satisfaction gained by siblings whose relationships belonged to each of these equity categories.

Subjects who felt underbenefitted by their sibling were significantly less satisfied than those who were overbenefitted or equitably treated. Though there was a trend for overbenefit to yield lower levels of satisfaction than strict equity, the difference did not achieve statistical significance (see Table 4).

Equity and Conflict-Resolution Style


Table 5 shows how the styles of conflict resolution siblings routinely practiced with one another related to patterns of equity or inequity in the sibling relationship.

Conflict-Resolution Style and Satisfaction

Table 6 shows the correlations between satisfaction with the sibling relationship and respondents' reports of their own and their target sibling's typical strategies for resolving the conflicts arising between them.

Siblings who perceived their relationship with one another as strictly equitable were less likely to employ aggressive or attacking conflict-resolution strategies and viewed their sibling as using more constructive mutual problemsolving than those who felt overbenefitted or exploited. Possibly this may reflect the equity-restoring properties of effective airing of views, listening to the other's perspective and mutual negotiation. Alternatively, siblings who use attacking methods of dealing with conflict may create perceived inequities for self and/or their sibling through the act of aggression itself.


Table 6 : Correlations between Satisfaction and Conflict-Resolution Style


These results support the differentiation between destructive and constructive conflict processes that was outlined earlier. Both attacking and avoidant strategies were destructive to the extent that they were linked with low satisfaction, whereas mutual problem-solving and satisfaction were positively correlated.


Sibling Equity and All Other Variables Combined

Table 7. Correlations between degree of inequity in the sibling relationship and other variables

Table 7 shows the patterns of univariate correlation between the degree to which the sibling relationship departed from strict equity (irrespective of whether the direction of the discrepancy benefitted or exploited the respondent) and the other major variables included in this study. As these results indicate, the experience of inequity in the sibling relationship is associated with less favourable outcomes than is the perception of strictly equitable fairness between siblings. To the extent that they feel either under- or over-benefitted, adolescents are inclined tO experience diminished relationship satisfaction. In addition, siblings whose relationship is inequitable are inclined to disagree frequently with one another over issues like money, chores, each other's behaviour, and moral values. In line with the results for categorical equity discussed earlier, there was also a tendency for hostile conflict resolution to be practiced by siblings in inequitable relationships.
