Context: Patients with diabetes face various physical and psychological problems such as depression, anxiety, disability, low mobility and obesity leading eventually to decrease quality of life. As a result, life quality is so important about diabetes and its treatment. Aims: The aim of this study was to determine the effectiveness of cognitive therapy on quality of life in patients with diabetes. Subjects and Methods: The research method was semi-experimental with pretest/posttest/follow-up and control group design. The population of the research were included all patients with type II diabetes who were referred to the Diabetes Clinic of Ganjavian Hospital. The sample volume included 40 subjects and an available sampling method was applied. Moreover, the substitution between control group and experimental group was randomly implemented. To collect the data, diabetes quality of life questionnaire was used. The intervention group has been received therapeutic sessions, and the control group was in waiting list. Data were collected through questionnaire of quality of life. Results: The results of the covariance analysis showed that cognitive therapy improved the quality of life in the experimental group in the posttest and follow-up stage (P < 0.05). Cognitive therapy training can be effective in improving the quality of life in patients with type II diabetes (P < 0.05). Conclusion: In order to findings, it can be concluded that the presentation of cognitive therapy beside other medical interventions is as a part of comprehensive treatment and care of diabetes.

  Introduction Top

Diabetes is a heterogeneous group of metabolic diseases that their characteristics are chronic raising of hyperglycemia and carbohydrate, fat, and protein metabolism disorder, and as a result, it has created some deficiencies in insulin secretion or insulin action[1] that increasing the blood sugar is common characteristics of this heterogeneous group. The World Health Organization[2] has determined four main types of diabetes: diabetes type I, diabetes type II, gestational diabetes, and secondary diabetes to other states. Diabetes type II is the most common form so that 85%–95% of patients with diabetes have this type of diabetes in developed countries and in higher level in developing countries.[3]

On the other hand, the chronicity of diabetes along with its potential side effects often results in high financial costs as well as a decrease in life quality and changes of the lifestyle for the patient and family.[3],[4],[5],[6],[7],[8],[9],[10]

Diabetic patients faced different physical and mental problems such as depression, anxiety, weakness, inactivity, and obesity that at last lead to decrease life quality. As a result, life quality is so important about diabetes and its treatment.[11] Life quality is defined as a multidimensional concept that has health compass and physical performance, mental health, social performance, satisfaction with treatment, concern about the future, and being well sense.[12] There is a mutual relationship between illness and quality of life, and physical disorders and physical symptoms have a direct impact on all of dimensions of quality of life. Therefore, the necessity for paying attention to evaluate new treatments, to determine and reduce costs, to identify all aspects of dissatisfaction with treatment, self-efficacy, self-care behaviors, to control blood sugar and its side effects as a result of these factors impact on the life quality is highly felt;[13] there is a clear and obvious relationship between quality of life and chronic diseases such as diabetes,[14] and quality of life of diabetic patients is one of the aims of diabetes management.[15] The increasing prevalence of diabetes in Iran and the increasing risk of diabetes complications showed the need for the present research in the country. According to this topic that one of the main aims in diabetic patients' treatment is improving the quality of life to gain a natural life, it is necessary to determine how the impact of quality of life to reach this aims.[4],[16] However, mental disorders with diabetes often have neglected and do not try to treat it. Researches show that cognitive therapy has effect on symptoms as pharmacotherapy has on it.[17] The therapeutic cognition that Aaron Beck is its presenter focuses on cognitive transformations which are assumed to have a role in the formation of mental disorders. The purpose of therapeutic cognition is to eliminate psychological problems and to prevent the relapse of the disease through identifying negative cognitive processes and to create different, flexible and positive thinking methods as well as practicing useful cognitive and behavioral responses.[18] Hence, in this study, the effectiveness of cognitive therapy on quality of life in patients with diabetes type II was studied.

  Subjects and Methods Top

The research method was a semi-experimental with pretest/posttest/follow-up and control group design. The statistical population were included all patients with type II diabetes aged 25–45 years who have treated in the Ganjaviyan Hospital Diabetes Clinic and 1 year of their diagnosis should be past. We used an available sampling method, and the sample size was 40 patients; the replacement of the patients in the intervention group and the control group was randomly. The inclusion criteria of this study were as follows: (1) having diabetes type II, (2) at least diploma education, (3) lack of psychic and personality disorder, and (4) age range between 25 and 45 years. The exclusion criteria of this were as follows: (1) having psychic and personality disorder and (2) the absence of more than two sessions of intervention.

Tools for this research included demographic information questionnaire for measuring demographic variables, and the questionnaire was codified by researcher, and in fact, it was description of the patients who had participated in the research and information consists of age, sex, occupation, level of education, income, occupation and level of education of parents and so on.

Diabetes quality of life

Measurement D-39, which has been developed to assess the quality of life in patients with diabetes, has 39 questions and 5 dimensions including control diabetes, anxiety and concern, social press, energy, and mobility; physical reaction is assessing in the Likert scale from 1 to 7. Scores range from 39 to 273. Above scores indicate low quality of life. This scale has been validated in a sample by 460 patients with diabetes type I and II.[19] Coefficients of Cronbach's alpha were different dimensions from 0.81 to 0.93 which indicates high internal homology of this scale.

Then, both groups were evaluated before therapeutic intervention. Then, on the experimental therapeutic intervention, therapy of cognition group was applied based on the group methods, and the meetings are held weekly for 2 h (ten sessions). The control group did not receive the therapeutic intervention in a group. Then, the two groups were evaluated by the use of post-test and after three months, the re-evaluation was carried out to follow up in order to measure the effect of the independent variable (group therapy intervention) on the dependent variable (post-test scores and follow up).

Brief description of the sessions based on Beck's cognitive therapy is shown in [Table 1].

  Results Top

The average age of the participants of cognition therapy experimental group is 41.25 and of control group is 41.30. The education of the participants in this research was from elementary to bachelor degree that diploma has appropriated the highest frequency. Quality of life scores in both groups is shown in [Table 2].

The average score of life quality in pretest phase in the experimental group (cognition therapy) was 152.17 and in the control group was equal to 155.59. Furthermore, the average score of life quality in the phase of posttest in the experimental group (cognition therapy) was 147.49 and in the control group was equal to 157.33. Finally, the average score of life quality in the follow-up phase in the experimental group (cognition therapy) was 148.53 and in the control group was 154.16. Considering that, the aim of the research was determining the effectiveness of cognition therapy in improving quality of life of in diabetes patients, and the research hypothesis was analyzed using covariance analysis. Utilizing the covariance analysis test requires some essential assumptions to be observed including the regularity of the dependent variable scores and control, the homogeneity of variance and the homogeneity of the regression lines. In this study, these assumptions have examined. The assumption of the regression lines' parallel is analyzed. It indicated that this assumption is between group and pretest. [Table 3] shows the result of the ANCOVA test.

As it is shown in [Table 3], after deletion the effect of the sync variables on the dependent variable, they have calculated according to the F coefficient. Once the effect of the synchronous variables on the dependent variable is eliminated and it is calculated according to the coefficient F, it is observed that there is significant difference among the moderated averages of the participants' life quality scores in terms of group membership (experimental group and one control group) in the post-test phase (P < 0.01).

Therefore, the hypothesis of the research was confirmed. So that, there was a significant difference between two groups' average scores of life quality, and the experimental group of cognition therapy had an influence on improving life quality of participants in posttest and follow-up experimental group. The amount of this rate's effect in the posttest is 49.9%. The statistical power near to 1 and significance level near to 0 represent the sample's adequacy. This effectiveness was not observed in the follow-up phase.

  Discussion Top

The results of covariance analysis related to the hypothesis of this research showed that there was a significant difference between the average of adjusted scores of life quality of attendees based on the membership of a group (the experimental group and a control group) at the stage of posttest and follow-up (P < 0.01). Therefore, there was a significant difference between the average scores of life quality and of two groups, and the experimental group of cognition therapy had an influence on improving life quality of participants in posttest and follow-up experimental group. It has not found a research exactly similar, but these findings to some extent are match with researches of Rubin and Peyrot,[20] Tankova et al.,[21] Ghavami et al.,[11] Nagelkerk et al.,[8] Saito et al.,[14] Berk et al.,[22] De Groot et al.,[23] Forman et al.,[24] Safren et al.,[25] Safren et al.,[26] Shomaker et al.,[27] and Stagl et al.[28] In this study, the effectiveness of psychological treatments is discussed on the quality of life of diabetic patients.

To determine the results, it can be said that diabetes is a chronic disease and noncommunicable which hyperglycemia is looking for a reduction of insulin secretion, resistance to insulin action, or both of them. The people with such disease in addition to early or late side-effects, such as hypoglycemia, and vascular involvement, pressures from disease control, observing therapeutic programs, complex and costly care, frequent visits to a physician, various tests, will also face concerns about the future and the probability of catching the disease for the children, social and familial disorders, sexual problems and work disorders, like other chronic diseases. In other words, this disease can have a negative impact on the progression of the created side effects, psychosocial status, and personal, familial and emotional relationships. In fact, the incidence of diabetes disrupts the orderly flow of life and affects the quality of life in different aspects, due to disease complications and long-term treatment. Therefore, reform of quality of life not only is beneficial for diabetics but also medical and health-care costs are reduced. On the other hand, according to the clinical observations of the researcher and referring to the protocol therapeutic used in this research, we can understand that the cause of this impact is changing the attitude of patrons in the first session. It is due to irrational thoughts and negative cycle of thoughts, and the aim of treatment is dealing with negative thoughts from the first meetings. The subjects of this research (diabetes patients) have welcomed this new attitude.[18],[30]

In total, by explaining the above findings, it can be said that people learn in the cognitive therapy how to face with different issues and problems in life completely and solve them and alternative existing issues and problems on solving them, and they were successful in focusing on them. Hence, they learn to change ways of facing with issues and events.

  Conclusion Top

The goal of this approach is the identifying and minimizing the cognitive distortions and controlling problem and logical analysis. In psychotherapy, it is believed that what the references learn in the treatment society, it becomes common gradually and after a while his life's positions were generalized. Hence, considering the fact that lifestyle is a collection of behaviors, functions, and his or her thinking approach in different situations, and since treatment can generally change these behaviors in relation with his/her treatment condition, it is possible to expect that such change could be seen later on in other situations and circumstances of his/her life. It can be expected that later this change can be seen on other conditions and situations of his life. The patients who have powerful skills in diabetes were tended to report flexible lifestyle, and more desirable quality of life associated with diabetes in comparison with the patients lacks this skill. This research proposes the need for more attention of the problems and the roots of these patients and proper interventions to improve them.
