Over the years, there have been huge controversies and debates regarding the issue of addictive personality. As a result, a number of studies have been conducted to investigate the same. One such study is the relationship between addictive personality and men with excessive alcohol consumption and social stability. Therefore, this paper will critique the study in line with descriptive statistics aspects.
The authors of the article sought to answer a number of questions in their research project. Firstly, they sought to answer the question relating to the onset of addiction. Secondly, the research project aimed at investigating why individuals become addicted to alcohol when they are socially stable. Lastly, the research paper aimed at answering the question that relates to the kind of personality traits exhibited by alcohol addicts.
The hypothesis of the research was that male individuals with excessive alcohol consumption do not have a specific “addictive” personality. Therefore, according to statistical requirements, the hypothesis was tested using two methods: T-scores (mean ± SD: 50 ± 10) and the Soft Independent Modelling of Class Analogy (SIMCA) Principal Component Analysis (PCA) (Berglund et al., 2011).
Indeed, the article employed a number of statistical aspects in a bid to provide enough information regarding the research topic. For instance, the researchers used normative T-scores (mean ± SD: 50 ± 10) to summarize individual raw data obtained from the personality test KSP. In addition, The Soft Independent Modeling of Class Analogy (SIMCA) Principal Component Analysis (PCA) was used to assist in pattern recognition and image compression. Therefore, this is a good indication that the researchers observed statistical aspects of the research. Personally, I would also use pie charts to represent the information. This is because pie charts have more appealing visual representations and conclusions can be drawn faster.
Despite efforts by the researchers to prove that male individuals with excessive alcohol consumption do not have a specific “addictive” personality, there are limitations and assumptions that can be seen in their study. Firstly, the study included only the middle-aged men individuals. Secondly, the advertisements information suggests that the participants recruited were mainly fit for investigating pharmocotherapeutical interventions for excessive consumption of alcohol (Berglund et al., 2011). Therefore, in line with these limitations, the assumption was that the information gathered could be generalized to the larger population, but was wrong. In addition, the researchers made assumptions while recruiting the control group from population-based Swedish Twin Registry that it did not consist of individuals with excessive alcohol consumption. In order to address these limitations, I would have included men with a reasonable age range. I would also use a control group that has already been vetted and found free of excessive alcohol consumption.
In regard to statistical testing, the researchers used normative T-scores (mean ± SD: 50 ± 10) to summarize individual raw data obtained from the personality test KSP as well as the Soft Independent Modelling of Class Analogy (SIMCA) Principal Component Analysis (PCA) to assist in pattern recognition and image compression. One major reason that inspired their choice of statistical testing method and especially the use of PCA is that it handles many variables and few observations and also few variables and many observations (Berglund et al., 2011).
The findings of the author(s) indicate that indeed there is no specific “addictive” personality linked to individuals with excessive alcohol consumption. This can be well interpreted from the KSP scales that showed individuals both in the control and study group had mean values that were within the normative range. In addition, the score plot in the PCA did not reveal any between-group separation.
