Thesis (PhD. (Clinical & Applied Psychology)) --University of Limpopo, 2013 / This study aims at developing an optimal psychological assessment procedure for determining primary residence allocation for children whose parents are divorcing. The research consisted of two studies: the first study focused on “translating” 13 identified legal constructs formulated by Justice King for safeguarding the best interests of children and the identification of suitable psychometric instruments that can be used to determine how effectively a particular family is functioning. These 13 legal constructs were converted into psychological constructs by three independent clinical psychologists. Following this a psychological assessment procedure for children and parents within a divorce context was developed incorporating the newly developed psychological constructs. The 2nd phase consisted of a sample of 39 families (26 families in the experimental group and 13 families in the control group). Six months later after primary placement the families were followed up in order to determine the psychological “health” of the families concerned using the Rosenberg Self-esteem Scale (RSE); Index of Family Relations (IFR); Eyberg Child Behaviour Inventory (ECBI) and the Family Assessment Device (FAD). The means obtained from both the experimental and control groups were compared using the MANOVA analysis. The results from the RSE concluded that the self-esteem of children in the experimental group, improved significantly to those in the control group. The IFR indicated that families in the experimental group had improved significantly at resolving family problems. According to the ECBI the children in the experimental group with behavioural problems improved significantly after primary placement. In all children in the control group did not improve significantly. The Family Assessment Device therefore indicated significant family cohesion. In summary the results indicate that the families in the experimental group were functioning at a higher level in comparison to the control group six months after primary placement.
