To answer the first question of the critique, the rationale for carrying out the research is discussed. As argued by Prezant and Marshak (2006), parents of children with disabilities need a broad range of support services from service providers and child care units so that they could facilitate positive outcomes for their children and these support services will have to be aimed in a manner that meets the needs of the parents of children with disabilities.
The needs of the parents may be varied and they may not always agree with professionals on what actions or services are truly helpful. In order to understand the parents viewpoints on the type of support services required, this research paper by Prezant and Marshak (2006) have focused on the aims of examining provisions of health care services provided to disabled children from the parents' perspectives.
The authors cite Kerr (1984) suggesting that the concept of help may differ from one person to another and that parents may have different opinions of help when compared with the professionals so it is necessary to understand parents view of what constitutes 'help'. The theoretical framework thus seems strong in this case as the authors provide their case and their argument in a convincing manner, drawing on a conceptual framework of help and service. Help could be understood not only on the basis of unmet needs but also the type of nature of help needed. Marshak and Present (2006) suggest that parental perspectives on the kind of services provided to their children are very important as parents decide on what kind of help should be available to their children and what is most suitable for their children. Considering this, the authors do provide a string rationale for the need to carry out their research.
The researchers aimed to study the parental perspectives about the nature of help they received from a broad range of professionals they interacted with and how this was of use if any for their children with disabilities. They followed a qualitative research analysis process. A survey instrument was designed and parental perspectives were taken on the nature of help they received from professionals. The instrument was based on Flanagan's critical incident technique (CIT). The authors write that "CIT was
