Group Comparison Study

An example of group comparison study was the study conducted by Elaine Walton , Mark W . Fraser , Robert E . Lewis , Peter J . Pecora , and Wendel K Walton in 1993 . It is a child welfare study of the impact of intensive in-home , family-based services on rates of family reunification . This study illustrates how an experimental approach can be used to meet the criteria for establishing causal relations . Walton together with his colleagues have recruited 110 families using a computer-generated list of children in substitute care . The sample included only children who [banner_entry_middle]

br had been outside the home for more than 30 days , whose return home was not imminent , but still the case goal , and whose parents were not dead or incarcerated . Fifty-seven families were in the experimental group while there were 50 families in the second group . Information was collected at the end of the 90 days , a 6-month follow-up , and a12-month follow-up

The control group in this study serves as the standard of comparison The families under this group were given traditional packages of routine services that were offered these services were provided out-of-home caseworkers were required to see each child only once per month , and the families were helped

Families in the experimental group received intensive services that were home-based . The intervention model was based on the idea that creating a relationship between the caseworker and the family , providing concrete services , focusing on the family and not just the child establishing or building a supportive network , and building skills would produce better client outcomes . Families in the experimental group received the services for 90 days and were seen in the home at least three times a week . The comparison group received the traditional packages of routine services that were offered these services were provided out-of-home , caseworkers were required to see each child only once per month , and the families were helped to locate services necessary to return the child to the home , such as mental health counseling and parenting skills training

Did the intervention make any difference ? As a short-term intervention the program was quite successful in that 53 children (93 ) in the experimental group were reunited with their families during the first 90 days of intervention whereas only 15 (28 ) of the control group were returned to their homes . After 15 months , of the 57 children in the experimental group , 44 (77 ) had returned home without any subsequent substitute care , 5 (9 ) had been briefly placed out of the home again 12 (21 ) who had returned home were back in substitute care , and one never returned home . In comparison , among those children who received traditional services , only 25 (47 ) returned home without any interruption , 5 (9 ) who had returned home were back in substitute care and 23 (43 ) never returned home . Although Walton and her colleagues (1993 ) point out various concerns , they conclude that the results are encouraging . Intensive in-home services that have a skills focus appear to be effective in the reunification of some families with… [banner_entry_footer]
