Level I shows the mildest damage, and level V the most severe. The research tool for measuring the quality of life is the WHOQOL-BREF, or World Health Organization Quality of Life BRE. It measures four dimensions: physical health, psychological, social relationships and environment. Validity and reliability tests were not discussed for these measures. Data Collection Data is collected through the measurement tools, GMFCS and WHOQOL-BREF for the control and experimental groups. The measure is basically a survey done in the hospital, where their children are being treated. For the control group, data collection process was not disused. Type of analysis used? Appropriate The t test was used for statistical analysis. Comparison across the measures was applied. These forms of analyses were useful and proper to the study because they establish correlation between the independent and dependent variables and use comparable dimensions. For the experimental group, more than half described their quality of life as good and 40% as not good or bad, while a fourth of parents of healthy children stated that their quality of life as very good. Furthermore, the quality of life of parents of children with cerebral palsy was considerably lower compared with the group of parents of healthy children. Physical health functioning, mental state, social relationships and environment were rated as better for group of parents with healthy children. The largest differences were in the appraisal of enjoyment of life, the importance of life, acceptance of physical appearance and experience of negative feelings. Authors concluded that the parents of children with cerebral palsy see their quality of life as good and are generally... Quantitative and qualitative The setting is unclear, although the researchers mentioned getting approval from the University of Tennessee Health Science Center and St. Jude Institutional Review Boards (IRB). It is possible that it is a hospital in or around the University mentioned. Independent Variable: Having children with a genetic disorder/disability and the resiliencyDependent variable: Parental stressControlled variables: Family factors, socio-economic issues, demographic aspects and child characteristics The Resiliency Model of Family Stress and Adjustment (McCubbin & McCubbin, 1993) is the conceptual framework of this research. It studied how parents go through stress and advantages by having a child with a disability. McCubbin and McCubbin started this model with the illness stressor. The family’s vulnerability (V) affects the impact of the illness stressor to the family. The resistance resources are composed of communication, patterns of functioning, and supports. The family’s appraisal (C) of the stressor is comprised of the family’s definition of the seriousness of the illness, its associated hardships, and resistance resources that allow them to cope with their conditions. Families also use problem-solving and coping strategies (PSC) to classify the problem into convenient elements and to achieve emotional stability. Authors used a sequential mixed methods design. This is a valid research design because the mixed methods approach is valuable for research that aims to improve professional practice.
