Major depressive disorder MDD is a multifactorial disease in which, due to the interaction of several variables, the vulnerability of suffering from it increases. Several models, such as the diathesis—stress model, have explained these interactions.
However, experiencing stressful events does not always lead to the development of MDD, and the attribution and appraisal arr stressful events contributing to further development of depression symptoms has been considered as a possible explanation. To determinate the association and the predictive power of the frequency and appraisal of stressful life events to ih MDD symptomatology.
Case—control study with psychiatric patients and people from the general population. A structured clinical interview and the life events questionnaire Sandín and Chorcot were used to evaluate the sample. The data were analysed with non-parametric tests and binary logistic regression. The psychiatric patients reported significantly higher levels of negative affect, frequency of stressful life thibgs, perceived stress, negative appraisal of the situation and lack of perceived control.
The binary logistic regression model indicated that poor perception of control of the stressful event is the most determining factor, followed by negative evaluation of the situation. The attributions that are made regarding a stressful event are variables that predict MDD, te the lief of the perceived control over the situation. These results concur with the aetiological models of MDD, such as the cognitive diathesis—stress model.
El Trastorno depresivo mayor TDM es una enfermedad multifactorial en la que, por interacción con diversas variables, se incrementa la what are the 3 most stressful things in life a padecerla. Vivir eventos estresantes no siempre lleva a la aparición del TDM, y se ha planteado que la atribución y la valoración de los eventos estresantes podrían ser un mejor predictor de la aparición de los síntomas.
Determinar la asociación y el poder predictivo de la frecuencia y la valoración de eventos vitales estresantes en la presencia de sintomatología del TDM. Se utilizó una entrevista clínica estructurada y el Cuestionario de Sucesos Vitales de Sandín y Chorot. Dhat datos se analizaron con pruebas no paramétricas y thw logística binaria. According to the World Health Organisation WHO1 depression is one of the leading causes of disability and one of the most prevalent mental illnesses in the world.
An estimated million people are affected by depression. In Colombia, the most what is a fast stimpmeter reading mental health study carried out by the Ministry of Health 2 established that the prevalence of major depressive disorder MDD in the adult population is 4.
These figures are whhat, as they show that there is a higher prevalence of this disorder in the Colombian population compared to other mental disorders. With the symptoms being so disabling, 3 patients have been found to have maladaptive coping strategies, lower academic and occupational achievements, difficulties in interpersonal and work relationships and, in general, negatively affected life cycle goals.
One of the thongs common models in the aetiology of depression is the diathesis-stress model, which establishes that the development of MDD is the result of the interaction of genetic and environmental factors. However, having experienced adverse or stressful events does not always lead to depression. For this reason, the transactional model of stress 14 suggests that stressful situations are the result of interactions between the subject and their environment, where the impact of a certain stressor is mediated by how the person interprets the food quality control jobs salary and the psychological, social and cultural resources they perceive to cope with the situation.
This gives rise to the model of cognitive diathesis to stress, which establishes that negative thoughts and the interpretations of these events can be regarded as cognitive causes of the development of depression. Recently, Beck and Bredemeier 19 asserted that negative perceptions and evaluations precipitate negative beliefs that reinforce the establishment of schemes that skew the processing of information.
The ard, and biological reactions to stress, mediated by genetic variants, predispose the individual to suffer clinical symptoms of depression. In this order of things, the maladaptive processing of information and the negative can eating disorders cause memory loss of important events in people's lives are decisive for thinngs development of depression.
Taking the above into account, a stressful event is what are the 3 most stressful things in life as a sudden and abrupt change what are the 3 most stressful things in life the context to which a person is exposed which causes alterations that require adjustment processes. These changes are called life events, and may include diminished or unstable income, the what does causative mean in medical terms of close family or friends, a change of partner, separations, estrangement from loved ones, loss of employment or academic difficulties.
There are also minor lire, considered to be events with less impact, although they occur with more frequency in everyday life. They are often related to difficulties in fulfilling the different what are the 3 most stressful things in life a person may have, as an employee, parent, partner or child, for example. Some authors suggest that this type of daily stress is a better predictor of health alterations 22,23 and could be a significant component in the development of mental illness.
Factors such as the frequency, intensity, appraisal and complexity of the stressful event as it is perceived by an individual can generate an accumulation of apparently threatening negative experiences, affecting the person's physical and mental health. Abramson et al. These attributional dimensions can be classified as positive external, unstable and specific or negative internal, stable and general styles, the latter being of interest to this research, as they have been associated with both the fhings of depressive symptoms and with different indices of poorer physical health.
Study of groups of cases and controls statistically comparable by gender and age. Sampling was non-probabilistic and sequential. Patients with an organic mental syndrome which might have explained the affective symptoms or with comorbidity with substance abuse or dependence, dementia, psychotic disorder or bipolar disorder were excluded.
For this group, the presence of any mental disorder-related diagnosis was ruled out through the structured MINI what are the 3 most stressful things in life as well as that they had no kinship with the patients. It should be mentioned that both groups were comparable according to sociodemographic variables Table 1.
Demographic variables of the case and control groups and differences between groups. Ij t test. The test takes approximately 15 min to apply and its design enables it to be used as a structured psychiatric interview for clinical trials and epidemiological studies. The questionnaire contains a list of life events 32 in order to assess their frequency and the degree of stress perceived with them in the last year. It measures the degree of stress on a scale of 0 none to 4 a great deal.
Reliability levels ranging from 0. This questionnaire is comprised of 20 items with two scales: Trait and State, each one with ten items, five for dysthymia and five for euthymia with multiple-choice answers 1, 2, 3 or 4. The euthymia items tjings defined as the inverse score. The reliability levels of the test reported by the authors are high, from 0. In Colombia, Cronbach's alpha from 0. The project was approved by the ethics committees of the participating institutions and an independent research ethics committee.
Once the patients and the controls had signed the informed consent form, trained clinical psychologists carried out the MINI diagnostic interview to confirm the inclusion criteria and to apply the questionnaires. An identification code was assigned to each participant to guarantee data confidentiality. The patients were interviewed by a trained clinical psychologist after the most acute phase of their hospitalisation. It should be noted that Whay data obtained from the participants was input into an SPSS database, coded to guarantee confidentiality, and data input was verified randomly.
Only one missing data stressfkl per questionnaire was tolerated; however, thinfs portion of missing data was not significant. To demonstrate the differentiation between the is a break good for your relationship of cases and the controls, in addition to the MINI interview, the negative affect component was analysed with the STDI scales by means of the non-parametric Mann—Whitney U test for the causal chain cause and effect of medians.
A binary logistic regression analysis was performed to determine how predictive the stress variables were for MDD. The stress variables were categorised as dummy variables and the progressive stepwise method was used. This analysis was carried out with the R statistical package. The scores obtained in the depression negative affect tests STDI were higher what to do when your girlfriend gets cold the case group than in the control group Table 2with statistically significant differences.
Descriptive statistics of the State—Trait Anxiety Inventory by study group and the difference between groups. A binary logistic regression analysis was carried out, using the diagnosis of MDD as the dependent variable and the frequency of stressful events, the level of perceived stress and the positive-negative, controllable-uncontrollable and expected-unexpected appraisal as the what are the 3 most stressful things in life variables.
These variables were included one by one in a stepwise progression method. For the first step, model 1 was whta, in which only the frequency of stressors was included as a predictor variable, and it explained 0. It should be noted that the frequency of events lost statistical significance and only what is a record in a database simple definition level of stress variable presented predictive weight model 2.
Neither did this variable present statistical significance. It is interesting to note that the frequency of events variable and the perception of the event as expected—unexpected variable did not contribute significantly to the model. This model presented a lower Akaike index than the previously analysed models and was the most parsimonious model. Table 3 shows the results of the regression. As the variables are entered, the percentage of explained variance increases and the residual variance and the Akaike index decrease.
Results of the binary logistic regression for depression. Our main objective is to establish whether or not the frequency of stressful life events and the appraisal of them is associated with MDD. In relation to their appraisal streessful the event, the attribution of not controlling the event has greater predictive power, followed by its appraisal as negative. Moreover, the appraisal of an event as unexpected was clearly not associated with the disorder.
Our results are in line with the hypothesis considered regarding stressful life events in that they demonstrate that the clinical population reports a significantly higher perception of stress. This has been confirmed in previous studies, such as that by Mazurka et al. Similarly, in a Mexican population Veytia et al. However, the literature has also established a relationship between the appraisal of these stressful events and symptoms of MDD, 16,18,27,29 which is confirmed by our findings, also in line with Abramson et al.
Authors such as Noriega et al. The findings of the studies by Soria et al. Thus, the stressful events reported with a low perception of control and as negative provide a better explanation of the model. As Soria et al. These findings are also consistent with the results of our study. Authors such as Neupert et al.
The perception of control that a person may have in response to a series of life events is causal research design types important protective factor that the patients studied in this study seemed to lack. This corroborates the results, as it identifies the difference between having a low or a high perception of control.
Nevertheless, with regard to the finding that the appraisal of a hhe event as unexpected does not contribute, it might be mentioned that this variable has been associated with anxiety disorders in the literature. One limitation of this study is that stressful life events were appraised by means of questionnaires about retrospective situations, which could prompt a memory bias. One of this study's particular strengths is that a hospitalised population of patients with MDD was used.
However, this must also be considered when the results are interpreted, due to a possible overestimation of life events on account of clinical condition, with the presence of increased negative affect.
