The results indicated that the omega coefficients of Somatic complaints, Depressive affect, Positive affect, and Interpersonal problems in the current Chinese sample were 0.811, 0.878, 0.725, and 0.722, respectively, and in the Dutch sample they were 0.746, 0.829, 0.755, and 0.570, respectively.
For example, the coefficient c9 is zero for complaint categories that do not exhibit linear long term trends, and the coefficients c10 and c11 are zero for categories which do not exhibit seasonality.
The association between the rates of complaints and years was measured using Pearson correlation coefficient.
Almost all Cronbach's alpha coefficients were >0.9 except one (intensity of complaints, 0.7), indicating high internal consistency (Table 4).
To evaluate the inter-rater reliability of Oral DRS, pairs of raters administered the scale to 40 randomly selected patients with complaints of oral dysesthesia symptoms and Cohen's weighted kappa coefficient was determined for each item.
Spearman rank correlation coefficients were calculated to study the improvement of physical complaints and ADHD core symptoms after having followed the diet.
They are not complete examples of the development of a HRQoL instrument (Wyrwich's chief complaint), nor do they suggest that Delta should replace the reliability coefficient (Norman's main objection).
Negative coefficients were found with depression, anxiety, stress, burnout, and health complaints [ 14].
The rate of complaints for medical issues according to hospital activity increased yearly (Table 1) with a correlation coefficient of Pearson of 0.87 (p = 0.01).
Multiple linear regression analyses, unstandardized regression coefficients, and 95% CIs were computed to examine associations between sleep complaints and fasting, 120-min, and AUC glucose and insulin.
The correlation coefficients varied between 0.1 and 0.3, with the strongest correlation occurring between psychosomatic complaints and self-rated health.
