They give rise to intense elaboration of catastrophic thoughts, intensifying pain perception. Pain experience has been treated mainly from the medical perspective, with a focus on the physiological process, without bearing what does variable mean in research mind the importance of intervening on the emotional component and the psychological suffering, which are. The idea is to create awareness about the problems affecting these patients and the impact of chronic pain on this population. Considering that suicidal ideation is a precursor to suicide attempts, this research is important because it will shed light on actions that may help prevent self-inflicted death and improve psychological interventions.

Exclusion criteria what does variable mean in research being in the process of filing for pension or indemnity payment by an institution due to pain, and inability to respond to the tests rresearch to cognitive impairment or altered sensoryperception. These criteria were established in order to reduce the probability of bias in variable measurements due to potential malingering by this type of patients.

Consecutive sampling was proposed because this method ensures that sample representativeness is similar to that obtained with probabilistic sampling. Sample size was calculated for the association between the risk of suicide risk and the quality of life, anxiety and depression variables. Considering that wat expectation was to perform 12 correlations in data analysis, the stated confidence interval alpha was corrected using the Bonferroni correction.

A sample size of 38 patients was estimated using the Epidat 4. This calculation was corrected taking into consideration that the relative efficiency of the Spearman correlation, compared with Pearson's, is 0. Finally, the suggested minimum sample size calculated for this study was 46 subjects. A census of the total population seen between December and January and that met inclusion and exclusion criteria was used, because the number of patients seen was not very high and a large percentage were diagnosed with endstage disease.

Therefore, given the resources available and the time of the study, what does variable mean in research was decided to collect the largest amount of data that met the sample size requirement for the correlation analysis. A total of 49 patients were ultimately evaluated. The SF is designed to evaluate health-related quality of life HRQoLand consists of 36 items grouped in 8 sub-scales. It was found to offer acceptable validity and reliability results for application in Colombia.

The HAD is two-dimensional scale that allows to screen for anxiety and depression symptoms in the hospital setting. It consists of 14 items, with Likert-type responses what is an equal set in math 0 and 3. In Colombia, this what are confounding variable was also shown to have acceptable validity and reliability.

This scale was designed by Robert Plutchik with the aim of separating suicidal kn from those who are not. The Spanish version was validated by Rubio et al. The original scale showed a consistency of 0. There is no validation of this scale for Colombia. A numeric scale was used to assess pain intensity, where 0 is no pain and 10 is the worst possible pain. Questions were asked about intermediate, highest and lowest pain level perceived over the previous week and the pain level at the time of assessment.

The study was approved by the El Tunal Hospital ethics and research committee. The most important recommendation, actually accomplished, was to refer jn patients with a risk of suicide, potential anxiety or depression immediately to the mental health service and to inform the treating physician. Frequencies, central trends and scatter were estimated for the variables measured; associations were also analyzed between the suicide risk variable and the other variables, using the Epidat 4.

The following calculations were performed in order to determine whether associations existed between the Quality of Life and Suicide Risk variables: Spearman correlations between the varjable obtained in each of the sub-scales of the SF and the score on the Plutchick Risk of Suicide scale; the Mann-Whitney U what does variable mean in research to determine if there was a significant difference in the sub-scale scores between the groups with or without a risk of suicide, and with or without suicidal ideation.

Overall, 49 patients were assessed in a group made up mostly by females The most frequent cause of pain was an underlying disease The mean age whah What is conversion rate for ecommerce failed to answer some items in some of the scales and, therefore, the results exclude the data lost in each case. It is noteworthy that in all measurements, pain levels were mostly moderate or severe.

In terms of quality of life, there was an overall decline in work and daily activities. The mean value on the What does variable mean in research Role scale This indicates that patients had had problems with their work and daily activities over the previous month.

The emotional role sub-scale assesses difficulties with work and other activities due to emotional issues, and the mean value was This indicates what does variable mean in research patients perceived that their emotional problems hindered work and other activities. For the physical component, a significant decline in physical function was identified, considering that the average score Analyses found significant inverse relationships between reseearch suicide risk scale and the scores obtained for the SF sub-scales of vitality, mental health, and the health component.

Of these, a b association was found with mental health and the mental component, and the relationship with vitality was also an important consideration. This result shows that patients with feelings of anxiety and depression and with a greater decline in activity as a result of mental health have higher scores on the suicide risk scale, and this relationship may be similar, although not as b, among those who feel tired and exhausted most of the time Table 7.

When the dichotomous analysis was applied to the results, a significant association was found between depression and the risk of suicide Table 8just like the correlation is high and significant when the direct scores obtained on the correlation scale are considered Table 9. Regarding the what does variable mean in research variable, the dichotomous analysis did not find association between anxiety and the risk what does variable mean in research suicide. However, when direct scale scores are considered, the correlation is intermediate and significant Table 9.

Finally, the most important objective of this study was to determine the association between the variables measured and the risk of suicide in the patients. It was found that suicide risk is not researcy to the levels of perceived pain; however, there was no difference between the levels of pain or disability between depressed patients with our without suicidal intention. In this sense, it could be argued that it is not pain per se that might result in suicidal ideation or suicide risk among the subjects assessed, but rather the emotional impact of pain.

In fact, all the significant associations were found between suicide risk and anxiety, depression, emotional role, mental health and mental component. Hence, it could be argued that pain has an emotional impact which, according to patient perception, affects normal functioning, and has an important relation with suicide risk.

Bearing in mind that this is an observational cross-sectional study, it is not possible varible generalize, and causal factors or directionality of the associations cannot be determined. Despite precluding generalizations due to the particular type of sample, it is generally considered that the findings serve as an initial approach to the problem. The results point to the need of conducting future studies to determine mediators between pain and emotional states, since it appears that this understanding is critical in order to improve the effectiveness of the interventions and reduce risks associated with anxiety and depression, including suicide risk.

Finally, we believe that it is important to include assessment and care of the mental component and emotional states in all protocols and care guidelines for chronic pain. Pedrajas J, Molino A.
