Rapid transition of health, population change, process of aging, and rapid lifestyle changes in addition to socioeconomic changes have led to a growing trend of disease, disability, and mortality due to noncommunicable diseases
[1]. Cardiovascular diseases, with 17 million annual deaths, are introduced as the most important cause of mortality around the world
[2]. Cardiovascular diseases include vascular system diseases affecting the blood supply to the heart, brain, and peripheral areas of the body
[3].
The main reason for mortality in Iran with 39.3% of total deaths is cardiovascular diseases, out of which 19.5% is related to heart attack, 9.3% to stroke, 3.1% to high blood pressure, and the remaining to other cardiovascular diseases
[4]. These diseases by creating various physical and psychological stressful factors (e.g., pain and lack of health), losing a job, sensory deprivation, feeling of imminent death, and various degrees of mental reactions (e.g., hopefulness, fatigue, and fear) cause a feeling of worthless and loss of self-confidence in patients
[5]. Due to the length and intensity of the disease, the physical, psychological, economic, and mental health of these patients significantly changes over time
[6]. Accordingly, it can be said that psychological factors can play a fundamental role in this process
[7].
Mental health is defined by the World Health Organization as a state of complete physical, mental, and social well-being (not only lacking disease with weakness)
[8]. The signs of mental health have intrapersonal resources enabling the person to continue his adaptive growth despite adverse situations and negative consequences and maintain his/her mental health
[9]. Corrsini also describes mental health as a mental state in which the person is relatively released from anxiety symptoms with the ability to constructively communicate and face stressful life stimuli
[10]. Therefore, decreasing mental health in an individual not only reduces his personal and social adaptability but also disturbs the safety and mental health of the family and other social groups
[11].
Hopefulness is among factors that play an essential role in facing problems and their resulted tension in the life of cardiovascular patients. It is useful as a potentially influential factor in the improvement and compatibility of the patients
[12]. Hopefulness can be described as a healing, multidimensional, and influential factor playing a vital role in compatibility with deprivation. In addition, physiologists have accepted that hope can have a psychological effect on illness
[13].
When a patient sees the matter rationally that there will be a better future, hopefulness is the feeling that is experienced within him/her
[14]. Hopefulness is a structure very close to life as the ability to design ways toward desired goals despite present barriers and agents with required stimulating factors to use these ways
[15]. According to this conception,
hope is powerful when including valuable aims. Furthermore, despite challenging but not resolvable barriers, hope can affect people in order to make their lives purposeful
[16].
Different treatment procedures have been applied to improve mental health and hopefulness among individuals with cardiovascular diseases
[17]. Short-term solution-focused therapy is a nonpathological approach to treatment that instead of focusing on problems and illnesses emphasizes finding solutions
[18]. In this approach, in opposition to the problem-oriented perspective, the emphasis is on finding solutions instead of focusing on problems
[19]. Maljanen et al.
[20] concluded in their study that short-term solution-focused therapy has been effective in the improvement of depression and anxiety disorders in annual follow-ups. Reddy et al.
[21] studied the effect of short-term solution-focused therapy on the improvement of moderate depression symptoms. They indicated that after short-term solution-focused therapy sessions, depression symptoms were relieved.
Given the increasing number of cardiovascular patients, their major problems in the mental health domain, and their hopefulness, it seems that many of these cases do not have sufficient knowledge
and skill to properly manage such problems.
Using solution-focused therapy for patients with cardiovascular diseases can decrease such problems.
Objectives
Considering the efficacy and improvement using solution-focused therapy for a broad range of clinical problems, the current study aimed to determine the effectiveness of solution-focused therapy in mental health and hopefulness among patients with cardiovascular diseases.
Materials and Methods
This was a quasi-experimental study with a pretest-posttest design, follow-up, and control group. The statistical population of the study included all cardiovascular patients referring to Isfahan Cardiovascular Research Center, Isfahan, Iran, within January to March 2018 with a history of heart attack or open-heart surgery in the last month. In this study, 30 patients with cardiovascular diseases willing to participate in the study were selected based on convenience sampling. The study participants met the study inclusion criteria and randomly assigned to experimental (n=15) and control (n=15) groups. The subjects were asked to complete questionnaires at the pretest and posttest stages. In this study, the training was collectively conducted.
The criteria for the diagnosis of cardiovascular disease was the diagnosis recorded in the patient's medical record by a cardiologist. The subjects of this study were selected from the patients referring to the Isfahan Cardiovascular Research Center Rehabilitation Unit. Moreover, the participants were informed about the plan and objectives of the study and treatment method. Finally, those who met the inclusion criteria participated in the study as a sample group. The patients in the experimental group, in addition to receiving regular medical care, weekly attended solution-focused therapy sessions (n=8) for 90 min. However, the subjects in the control group received just regular medical care. The study participants in both groups filled out the hopefulness and public health questionnaires at the baseline and immediately after the intervention (Table 1).
The inclusion criteria of this study consisted of the patients with coronary heart disease, including stable angina, unstable angina, and myocardial infarction. Moreover, the patients with angiography, at least in one of the coronary arteries, with 70% or more so-called angio-positive involvement were included in the study. The exclusion criteria were lack of cooperation, two consecutive absences during the intervention, and severe physical disability. In order to perform the study, all the subjects completed the questionnaires before and after the treatment sessions. The researcher also pledged to do this intervention for the control
group to follow ethical principles.
Snyderʼs Hopefulness Questionnaire
This scale with 12 items, including two subscales of pathway and motivation, has been developed by Snyder
[22]. The scores to the items were rated within a range of entirely wrong to completely right
[22]. The reliability of the Iranian version of this scale was confirmed through the internal consistency method and Cronbach's alpha coefficient of 0.89
[23]. The reliability of this scale in this study was also investigated using the internal consistency method with the Cronbach's alpha coefficient of 0.84.
Public Health Questionnaire
This questionnaire includes 28 items, which are based on a 4-point Likert scale (i.e., Never, Usually, Often, and Most often). In this questionnaire, as the points get higher, a lower level of mental health is reported. The public health questionnaire has been developed by Goldberg et al. in 1972, translated to Persian, and normalized in Iran. The reliability coefficient of the whole test has been reported as 0.88, and the reliability coefficient of the subtests have been calculated at 0.77, 0.81, 0.50, and 0.58, respectively. The questionnaire has sensitivity and specificity within the ranges of 0.84-88 and 0.77-93, respectively, with the classification error of 8.2%. The best method of scoring is according to 0, 1, 2, and 3, and the best score is reported as 23
[24].
The data were analyzed using descriptive and inferential statistics by SPSS software (version 22). Descriptive statistics include frequency tables, and diagrams, central indices, and scale dispersion indices (e.g., mean and standard deviation). Inferential statistics, including analysis of variance (ANOVA) and Kruskal-Wallis test, were used to compare age and gender between the two groups and ensure that the baseline characteristics of the groups regarding these two variables were similar. Analysis of covariance and multivariate analysis of covariance were used to analyze the data. Data analysis was performed using SPSS software (version 22).
Results
A total of 30 patients were studied in the solution-focused therapy (n=15) and control (n=15) groups. The mean values of participantsʼ age were reported as 57.73±9.39 and 53±9.81 years in the solution-focused therapy and control groups, respectively. Table 2 tabulates the demographic characteristics of the present study.
As it can be observed in Table 2, the significant level is higher than 0.05; therefore, both groups of the study were similar in terms of gender distribution and educational level. Table 3 presents the mean scores of the components of mental health and hopefulness in the experimental and control groups.
