We investigated unconscious aspects of the psychological experiences of siblings of disabled persons by using TAT. The results showed that compared with the control group of college students who had able-bodied brothers and sisters, the siblings of disabled persons easily turned their attention to the internal states of illustrated characters, and expressed greater empathy. Primary circumstances of conflict were family relationships, interpersonal relationships, and identity. Need for external events, interpersonal needs, need for pressure elimination, human pressure, environmental pressure, and internal pressure were displayed. Conflict resolution styles were divided into the following four types: self-resolution, depending on others, unresolved, and conflict avoidance. Internal mother-child relationships and internal sibling relationships were divided into the following four types: receptive, superficial, conflictive, and non-receptive. We compared each type of relationships with conflict resolution styles and conflict circumstances. We found that in both correlations, receptive, superficial, or conflictive types had self-resolution styles.
