Sibling Rivalry Scale Test - Description and methodology of the test
Parents, caregivers, and other adults can help a child answer this questionnaire about hypothetical situations involving a younger brother and then discuss the result. The Sibling Rivalry Scale Test offers a focused view of responses to sharing, protecting, spending time with, and encouraging a younger brother. It works as a practical sibling rivalry assessment for family reflection.
What This Assessment Explores
Questions place a child in hypothetical situations involving a younger brother: playing together, sharing, care, protection, praise, and staying close. These situations are presented in a sibling jealousy questionnaire, giving the child concrete actions to consider before the displayed scale is reported.
Four themes organize the item situations:
- Companionship covers playing, spending time together, and staying nearby.
- Sharing and inclusion concern offering possessions and joining activities.
- Protection and care involve imagined help, supervision, and defence.
- Positive regard covers pleasure, praise, and encouragement.
The displayed scale is Jealousy Toward Younger Brother (0-100). Its bands are Low jealousy (0-30), Moderate jealousy (31-60), and High jealousy (61-100). The catalogue defines this scale as the child’s jealousy toward a younger brother: higher scores indicate more pronounced rivalry and jealous feelings, scores above 60 are considered particularly unfavorable and may indicate significant difficulties in sibling relationships.
Methodology and Scientific Basis
Each item uses a direct Yes/No response, making this a structured self-report of hypothetical sibling situations rather than recalled events. The responses produce the displayed jealousy result, but individual answer weights and the aggregation rule are not documented; the bands do not show how either answer contributes.
Research on sibling affection, envy, understanding, and prosocial interaction provides relevant context. Dunn et al. (1981) examined first-born children’s reactions when a sibling arrived; Dunn and Kendrick (1982) described affection, envy, and understanding in sibling relationships; and Dunn and Munn (1986) linked sibling interaction with prosocial behavior. This questionnaire is conceptually consistent with those sources, but is not presented as an adaptation or standardized reproduction of any of them.
The result can be used descriptively to discuss responses toward a younger brother. Within this younger brother relationship test, adults can consider patterns of sharing, care, or praise without assigning them to a band. The bands are the catalogue’s descriptive result labels. Family circumstances, mood, expectations, and self-awareness may shape answers, so a brief self-report cannot establish a clinical condition or explain the relationship.
