The aims of this course are to teach the basic statistical approach and terminology, to teach the use of the SPSS for Windows package
program and its basic characteristics and principals, to perform the basic descriptive and analytical statistics by using SPSS for Windows
package program and to interpret the results.
At the end of the course, the participants will be able to perform descriptive statistics, select the appropriate statistical tests to compare
differences between or within groups and be able to draw some graphics by using the SPSS for Windows package program in a datasheet
which is composed by the course director.
The participants, upon completion of this course, will be able to generate and test hypotheses, compose a datasheet iusing the SPSS for Windows
program, enter data in the datasheet, transform the data to other forms, select the appropriate statistical test for comparison of groups and computation
of basic statistics, interpret and write the results, interpret the p value and confidence interval, and draw some graphs by using the SPSS program.
The participants will learn to calculate mean, median, mode, standard deviation, quartiles, frequency and percents as descriptive statistics.
They will learn and differentiate categorical, ordinal, and continuous variables by studying examples. To compare categorical variables, the
use of the chi-square test and interpretation of the results will be discussed. For continuous variables, the appropriate test will be determined
with respect to group numbers, whether groups are dependent or independent and whether the variables are parametric or nonparametric.
According to the existing conditions, the participants will decide when they should use the independent samples t test, ANOVA, paired samples
t test, or repeated measures of ANOVA as parametric tests and Mann Whitney U, Kruskal Wallis, Wilcoxon ranked signs test, or Friedman test
as a nonparametric tests. They will also use correlation analysis to determine the linear association between continuous and ordinal variables.
By using the SPSS program, participants will compose bar and pie graphs for nominal and box plot graphs for continuous variables to
demonstrate the results.
Key words: descriptive statistics, p value, confidence interval

Despite a high prevalence of somatic symptoms without demonstrable organic cause in nearly every branch of medicine, understanding,
classification and treatment of these disorders have posed a considerable challenge.
As the DSM-V is in development, the proposed changes in comparison to the DSM-IV can be seen to reflect the current understanding of
non-organic physical symptoms. It is likely that somatization disorder, hypochondriasis, undifferentiated somatoform disorder and pain
disorder will be combined into a new category entitled “Complex Somatic Symptom Disorder” (CSSD) which emphasizes the symptoms
plus the patients’ abnormal cognitive processes. The term “complex” is intended to indicate that the symptoms must be persistent and
must include both somatic symptoms (criterion A) as well as dysfunctional cognitive processes (criterion B) for the diagnosis to be made.
Cognitive processes such as dysfunctional attention focusing, symptom catastrophizing, and symptom expectation that may be included
in criterion B also show the influence cognitive models have exercised in the understanding of these disorders.
These cognitive processes have to be evaluated against the background of possible psychiatric comorbidities, current life stressors,
possible past traumatic events and learning experiences that shaped emotion regulation in an unhelpful way. Contributing to the
maintenance of symptoms and resulting from dysfunctional cognitions are behaviours such as imbalanced level of activity, avoidance
and safety-seeking and reassurance-seeking behaviors.
