[. . .] This is examined utilizing a Pearson product-movement correlation. The results are analyzed utilizing multiple linear regression analysis which looked at the correlation between the initial motivation to change and clinical improvement, with the inclusion of multiple factors including other potential confounding variables, including depression symptoms as assessed with the Beck Depression Index. It was determined for there to be confirmation of any statistically significant relationship between the motivation level and the clinical outcome there would need to be a p-value lower than 0.05.

The research indicated that there was no significant difference clinical outcome between patients who receiving the pharmacological treatment, and those who were not. There was found to be a direct positive correlation between the initially assessed motivation to change and the clinical outcome, with a p value resulted with statistical analysis of p = 0.007. A significant correlation was found in the decrease in the number of binges and vomits per week that took place. Other factors were also examined, including the duration of the disorder, and body mass index, but no statistically they should was found between a decrease in symptoms and these potential influences.

The research appears to support the hypothesis, that motivation at initial assessment is a predictor of the patients behavioral response to treatment, and that higher levels of motivation present in the patient at the initial assessment are likely to result in decreased bulimia symptoms following participation in the standardized treatment.

The research approach appears to be extremely well-designed, with a sample of similar patients entering the same program, which helps to reduce the potential for extraneous or confounding influences remain unidentified. However, this does not mean there is the total elimination of external factors. One aspect of the research design which may require some consideration is the choice of the sample. The sample was predominantly female, with only one male participant. While it is generally recognized that bulimia nervosa is more prevalent in females, the inclusion of only a single male may indicate a skewing biasing of the results, or invalidate the results for males. Therefore, a study on a greater scale, with the inclusion of a larger number of male participants may be very useful, especially in assessing the condition with reference to gender.

The utilization of the generally accepted tools helps to increase the perceived credibility of the report, and helps to reduce uncertainty as these tools had already been tried and tested. The research tools had been utilized for both adults and adolescents in the past, and provide an in-depth insight into the symptoms and psychology of the patient. In the future further research may be enhanced with the use of qualitative rather than quantitative research, with researchers looking not only at the linkage between motivation and a reduction of symptoms, but examining how and why this relationship occurs. As the research is seeking to identify factors that are relevant to recovery, factors such as potential causes and influence of motivation, and why it has such a significant impact, may all be important. However, the initial stages of research need to look at the phenomena, describing what occurs, before looking at how and why.

Overall, the research is well-designed and when implemented, presents characteristics associated with reliability, with a robust design that minimizes the potential for external influences, and takes place on a relatively long scale, assessing the results between six and eight months following the commencement of treatment. It is a very useful research project and will aid in the understanding of adolescent patients suffering from bulimia nervosa.
