The Barriers and Facilitators of Self-Management Among Adults with Type 2 Diabetes Mellitus: A Trans Theoretical Model (TTM)-Based Mixed Method Study in Iran.

AIM: This study planned to determine:( 1) the behavioral intention or profile of patients with type 2 diabetes mellitus (T2DM) based on the stages of the change model, and( 2) to explore the perceived facilitators and barriers of self-management (SM) in a sample of Iranian patients with T2DM.
METHODS: This was a mixed method study, accomplished in two phases. In the quantitative phase, 246 subjects with T2DM participated. They were classified according to items such as regular use of blood-glucose-lowering drugs, having a healthy diet and performing physical activity to pre-action and action groups. Socio-demographic and anthropometric information were collected, and a phenomenological qualitative study was conducted, and data collection continued until saturation achieved by 10 subjects in pre-action and 12 subjects in action groups. Four focus group discussions in the field of SM were accomplished. Analysis of quantitative and qualitative data was conducted by the SPSS and MAXQDA software, respectively.
RESULTS: The mean age and duration of illness among the subjects were 53.9±7.1 and 6.9±4.9 years, respectively. The barriers of SM in action and pre-action stages were as follows: lower socio-economic status, poor performance of treatment team, physical-intellectual factors and lack of planning to change. The facilitators stated in the pre-action and action stage in the field of SM were satisfaction from treatment, planning, belief in diabetes, treatment team's support, nutritional knowledge, and religious beliefs.
CONCLUSION: This study indicated facilitator and barrier factors in SM based on TTM in action and pre-action groups. Healthcare professionals should consider these findings to improve the patients' outcomes.

Introduction

Diabetes is a chronic metabolic disorder characterized by elevated blood glucose level, which could lead to serious complications if it is not diagnosed or managed properly. Type 2 diabetes mellitus (T2DM) occurs when the body cannot effectively use the insulin produced by pancreas; hence, blood glucose level rises.1 In 2014, an estimated 422 million adults were living with diabetes worldwide which is about four times higher than the conjectured figure, i.e. 108 million in 1980. During this period the prevalence of T2DM has increased from 4.7% to 8.5% in adults’ population.2 Delayed diagnosis and deficient control measures could lead to a number of devastating consequences including macro-vascular (heart failure and stroke) and micro-vascular (nephropathy, neuropathy leading to amputation and retinopathy leading to blindness) complications in patients afflicted with diabetes.3

It has been indicated that self-management (SM) of chronic diseases reduces the burden of diseases on patients and improve treatment outcome. In line with such recommendations, SM education for patients with T2DM has been proven to be beneficial for better therapeutic outcomes and delaying prolonged complications.4 The conventional SM of T2DM included medication adherence, lifestyle modification and regular checkups by a professional health care provider. However, existent research evidence indicates that successful SM of the disease faces challenges and difficulties.5,6 Implementing health policies with desired level of efforts for prevention strategies can overcome the impediments that hinder self-control of the disease and prevent its devastating complications. In the absence of effective and sustainable strategies to reinforce active engagement of patients with T2DM in their disease management process, the proceeding results could be overwhelming for patients, their families and communities. Patient’s competency and psycho-emotional readiness to change and interplay several contextual factors influence their preparedness in making informed decisions.7–12 Due to the significance of SM on T2DM alleviation and the patients’ quality of life, recognition of potential facilitators or obstacles of virtuous SM could be a determining field in investigating pertinent health care provision.13

In most health care centers, certain models are used for assessing and evaluating SM among T2DM patients.6 One of these models is TTM, which is widely used in health-promoting systems for guiding behavioral changes. The TTM enhances individual’s motivation for SM. This model comprised four constructs: stages of change (SOC), processes of change, decisional balance and self-efficacy. Decisional balance means pros and cons, and in this construct, an individual assess benefits and barriers of changing his/her behavior and focuses on the importance of positive and negative perceptions regarding the outcome of changing his/her behaviors.

To have a realistic view on the SM intermediates of TTM, the SOC was used to segment study participants based on their progress across the spectrum of the model’s phases, i.e. pre-contemplation, contemplation, preparation, action and maintenance. In the pre-contemplation stage, adults with T2DM have no intention to take a proposed action within the next 6 months while in the contemplation phase patients with T2DM taking action within the next 6 months is intended. Those in the preparation phase are pondered to do the considered behavior within the next 30 days and in the action phase, the patients with T2DM actually change his/her behavior. The last span of the change process is consistently continuation in prolong of the aspired behavior for over 6 months.14,15

Objectives: Thus, this study planned to determine: 1) the behavioral status of the patients with T2DM based on the SOC construct of TTM model, and 2) to explore perceived facilitators and barriers of SM in a sample of Iranian patients with T2DM.

Materials and Methods

Study Design

A mixed method sequential explanatory design was applied in this study. The study was conducted in two phases; first, the quantitative data were collected followed by qualitative data. The purpose of the qualitative phase was to explain and interpret the findings of the quantitative phase. For example, a survey may be used to collect quantitative data from a larger group. Members of that group may then be selected for interviews where they can explain and offer insights into their survey answers.

To divide the study population into different interview groups based on their progress across phases of TTM and to inform the qualitative phase of the study, a preliminary quantitative probing study was conducted. Based on the findings of this initiatory phase, a phenomenological qualitative study was conducted through utilizing focus group discussions (FGD) in a typical sample of Iranian with T2DM regarding potential barriers or facilitators that could influence their SM practices.

Subjects Selection

The convenient sampling method was used to recruit patients with T2DM referring to a private clinic in the city of Ardabil, North West of Iran. Medical profiles of 510 patients with T2DM were assessed for inclusion criteria, i.e. being diagnosed with T2DM for more than a year, being 30–70 years old, using glucose-lowering drugs (BGLDs), not having renal, hepatic, cognitive, learning, visual and hearing disorders and having glycated hemoglobin (HbA1C) more than 7% or fasting blood glucose (FBG)>126 mg/dl.16,17 Exclusion criteria were using insulin, following specific diets, having pregnancy-related diabetes and breast-feeding, and patients with severe complications. After checking the patients’ laboratory test results, and being assured of their congruousness with the inclusion criteria, 246 participants meeting the preliminary inclusion criteria were invited to participate in the study. The study aims and procedures were thoroughly explained to the selected participants.

Quantitative Phase

Data about the participants’ socio-demographic and anthropometric status and family history of T2DM were collected through asking a few simple questions. A researcher-designed questionnaire was also applied to collect data to classify the participants according to TTM phases. The questions were about regular use of BGLDs, following of a healthy diet and a sufficient level of physical activity (PA). Content and face validity of the questionnaire were assessed by a panel of experts. Construct validity was carried out by exploratory factor analysis. The validity and reliability of the questionnaire were satisfying.

In BGLDs and the PA section of the SM questionnaire, the first choice of the multiple-choice questions referred to pre-contemplation, the second to contemplation, and the third, fourth, and fifth ones to preparation, action, and maintenance, respectively. In the healthy diet section, the Likert scale was used, and for allocation of subjects in each stage, the mean scores were considered. Hereby, those who obtained scores between 8 and 14 were in the pre-contemplation section, while the scores of 15–20, 21–26, 27–32, and 33–40 indicated the contemplation, preparation, action, and maintenance sections, respectively.

According to the SOC construct of TTM, the patients were divided into pre-action (pre-contemplation, contemplation and preparation) and action (action, and maintenance) stages. According to the scale, a score of 1–3 indicated that the patients were in the pre-action stage, and a score of 4–5 indicated that the patients were in the action stage in BGLDs and PA. Regarding following a healthy diet, the mean score was obtained to determine each patient’s position. A score of 8–26 indicated that the patients were in the pre-action stage. In addition, a score of 27–40 displayed that the patients were in the action stage.18 According to the SOC construct of TTM, the patients were divided into pre-action and action stages. Afterward, they were assessed based on the facilitators and inhibitors of SM related to the decisional balance construct of TTM.

The Study Complimentary Qualitative Phase

Focus group participants were selected from the quantitative phase subjects in two groups, pre-action and action SOC of TTM, based on the purposive sampling method: Written informed consent to FGD was obtained from patients with T2DM willing to participate in FGD. Individual group meetings were also held to assess the facilitating and inhibiting factors of SM among the patients.

In each focus group, 12 patients with T2DM were invited, but 10 and 12 patients participated in the study, respectively. In both pre-action and action groups, two FGDs were considered. The meetings of the focus groups were held in a suitable and private room in a private clinic. The meetings were conducted in 60–90 minutes in the winter of 2017. In addition, a female researcher (nutritionist) supervised these meetings as a viewer to facilitate the group discussions.

The FGD began with a general and open-ended question like “How is life with diabetes?” Afterward, every patient described his/her disease in one way. The next and pursuing questions were based on the information that the patient revealed. If needed, probing questions were also asked to achieve the purpose of the study. Information gathering in FGD continued until data saturation, which data were repeated in categories. All FGDs were recorded by digital recording appliances.

The decisional balance construct of TTM was assessed by gathering data in the qualitative section of the study. The qualitative phase was conducted based on the focus group guidelines.19

Statistical Analysis

The Study Preliminary Quantitative Phase

Descriptive analyses: frequencies (percentage) and mean [standard deviation (SD)] were performed for quantitative phase data. Statistical analysis was conducted using the SPSS Version 21 software (SPSS Inc. IL, Chicago, USA).

The Study Complimentary Qualitative Phase

Qualitative analysis was conducted by the MAXQDA 12 software. All interviews were transcribed and coded as follows: the data line by line; several times and the main concept and important sentences were extracted, summarized, and the codes were registered. The codes were categorized based on their similarities in the sub-themes. In addition, each of these sub-themes established the major themes in accordance with their resemblance. The first categories and the axi-coding were prepared, the data were categorized, the sub-themes were determined and the major themes were specified. Additionally, to be assured of the categorized codes, the sub-themes and major themes were corrected. One researcher implemented all these works, and after the primary coding for reliability, several researchers authorized them.20,21

In addition, 70% of the patients were overweight, and 30% were obese. To use BGLDs, 10% were in the action stage, 90% were in the maintenance stage. About following a healthy diet, 90% were in the action stage, 10% were in the maintenance stage. In addition, in relation to having PA, 20% were in the action stage, 80% were in the maintenance stage.

In the action group, 12 patients participated in the field of inhibiting SM (an appropriate usage of BGLDs) and stated three major themes, and the subjects stated, “Chemical medicine’s side effects causes no to use BGLDs”. Following a healthy diet had 3 major themes, and the subjects stated, “Feeling dizzy when eating is delayed” and “Separating food from family because of heartburn is caused by medications”.

The subjects stated three major themes in relation to having PA. One of the subjects said, “Cold weather makes me not to do exercise” Table 2 and Figure 1.

Discussion

In this mixed method study, the inhibiting and facilitating factors for SM of T2DM were investigated among a typical sample of Iranian patients based upon the SOC and decisional balance constructs of TTM. Patients who were in the action stage had higher scores in different parts of SM than patients in the pre-action stage, and also the action group had higher mean duration years of disease, higher percentage of family history of T2DM and educated in relation SM than pre-action group. Despite the common inhibiting items observed in both groups, lack of planning was reported as one of the main inhibitors of action in comparison to the pre-action stage. This finding indicates that patients in the action stage value planning and try to overcome not having time as the inhibiting factor. However, patients in the pre-action stage did not indicate this factor and they believed in arbitrary treatment, which was the main reason of unlikeliest of SM.

Despite the major themes reported by both groups, patients who were in the pre-action stage, claimed religious and Islamic beliefs were as important factors. However, patients in the action stage paid attention to appropriate planning for suitable exercising, using medicine and traditional treatment which motivate them to keep up with SM.

In FGD, SES factors such as lack of facilities, lack of glucometer, doctor or dietitian visits payment and medicine cost were indicated as the limitations of SM in both stages for several times. Similarly, in Mousavizadeh et al and Taha et al studies, financial pressure and social difficult situation were claimed as barriers of adherence to treatment and Fort et al indicated a lack of drug as a barrier in preparation of SOC.12,22,23 The difference between this study and Fort’s study was the design of the study. We can overcome these problems by introducing these patients to health centers in the cities that provide medical services,24 nutritional counseling, psychology, free BS and cholesterol tests. However, suitable economic condition and having convenience are facilitators of SM.

In this study, based on the situation, both groups mentioned family and social factors as inhibitors and facilitators of SM. These findings were similar to previous studies.12,22,25–29 Identifying family members especially daughters who can encourage and support patients about SM is an important supporting factor. This fact helps patients with T2DM obey their treatment because their role is very essential. Also, social institution and public organization’s support could be an important facilitator in SM. In some customs and religions, due to cultural and social limitations, certain exercises are not possible for women. Thus, it is essential for public organizations to build special parks and places with SM facilities so that women could exercise.

Diabetes is a chronic disease, needing a vast amount of behavioral changes and complex dietary surveillance. Social support, as one of the efficient and important factors of patient adherence to treatment, can facilitate SM behaviors and compatibility with disease.10

In this study, few patients were unsatisfied of the treatment team’s incomplete informing, that are not respondent and unsuitable education. Others declared treatment teams’ good behavior, support, prescribing accurate medicine and dietary education as encouraging factors for SM. They believed these behaviors were the reason for their adherence to treatment and continue referrals. These findings were similar to the results of many studies.22,25,30 Patient’s satisfaction of the treatment team is an efficient factor in improving their adherence to treatment.

One of the main aspects preventing SM in the pre-action group was arbitrary treatment. Usually, non-specialist’s recommendations and treatment provide wrong information about SM among T2DM patients. This fact leads to not using medicine or reducing its dose, failure of obeying diet or quitting exercise. These findings were in consistent with Shakibazadeh et al study.30

Additionally, similar to Shakibazadeh et al and Coornad et al studies, physical and intellectual factors were important factors that patients in the pre-action and action stages indicated as obstacles for SM.30,31 Due to the limitation of resources in developing countries, by overcoming physical and intellectual barriers we can achieve health and success in SM. In this study, patients in the action stage indicated overcoming intellectual, physical and psychological barriers as facilitating factors and they were able to overcome physical and psychological problems with this procedure. Also, they achieved higher scores in comparison to the pre-action group.

Similar to Carolan et al and Shaghaghi et al study, some of the barriers of SM in both the pre-action and action groups were the nature of the disease, physical-mental factors, losing weight after diabetes, not feeling satiety after eating and eating too much because of anabolism and catabolism dysfunction.27,32

Continental features and climate were two of the aspects mentioned as inhibiting factors for exercising in the sub-themes of physical factors. In both groups, cold climate was the barrier of walking in outdoors. According to Salehi et al study, 11.5% of the study population claimed air pollution as the main barrier.33 In another study, cold or hot weather was mentioned as the main inhibitor of exercise. However, by exercising at home with inexpensive exercising equipment or public exercises patients can overcome this problem.12,34

In SM, planning was indicated as a facilitating factor, especially in patients who were in the action stage. In order to not forget to use their medication, these patients brought their medicine to the food table and so in PA, not having enough time was inhibiting SM. Similar to few other studies, not having enough time and not planning for exercising were mentioned as limiting factors.35,36

In the action group, beliefs about diabetes such as understanding the longtime consequences of diabetes were mentioned as the facilitating and inhibiting factors. In the pre-action group, fear of amputation and high BS were claimed as facilitators of SM. In Doosti’s study, fear was indicated as a facilitating factor. Fear is a common respond effecting both patient and his/her family positively or negatively. In few patients, fear changes behavior positively and helps learn new things. In Shakibazadeh’s study, fear was reported as a motivating factor.10,30

Gaining information and knowledge about physical condition was one of the major themes, introduced as a facilitator for referral to doctor and controlling BS in both groups. In Fort’s study, lack of knowledge about the disease was another inhibiting factor in SM. However, in Doosti’s study, this factor was indicated as a motivator for SM.10,12

Similar to Dehghani’s study, religious beliefs were facilitating factors that were mentioned in the pre-action stage.37 In another study, adolescents who earned higher scores in religious beliefs had lower HbA1C. Religious beliefs help diabetic adolescents overcome stressful situations and should be considered as an important feature in treatment.38 Gaining information about the exchange list and reducing sweets and fats were considered as the facilitating factors of healthy diet in both groups. They claimed that by obtaining nutritional knowledge and information they could be successful in having a healthy diet. Similar results were also observed in another study.27

Another facilitator was overcoming intellectual-psychological factors. These factors were considered as sub-themes of physical-intellectual factors in the action stage. Self-efficiency has been related to the barriers of SM. This relationship indicates that patients who have higher self-efficiency feel fewer obstacles in the procedure of SM and have more SM activities.39,40

Traditional or alternative treatment was considered as a facilitator in SM in the action stage. Herbs such as cranberry, Nettles and Fenugreek seeds, walnut and olive leaves were reported as herbals that reduce BS and could be used along diabetes controlling drugs. These findings were similar to two review studies.8,9,41 Before the discovery of insulin and anti-diabetes medicine, patients with diabetes were treated with traditional and herbal drugs. Until now, 1200 herbal plants have been discovered to be useful in reducing BS and its consequences.42

The strength of this study was the use of mixed methods design and also, was using the trans theoretical model. In this study, patients were divided into pre-action and action groups and assessed based on different levels of self-management. The facilitating and inhibiting factors were assessed separately in both groups.

The limitations of our study were using semi-structured questions, considering patients with different educational levels, economic status and accomplishing the study in a specialized clinic outside the diabetes clinic.

Recommendations

Determining the facilitating and inhibiting factors of SM can be useful in judging the success or failure of SM among T2DM patients. In this case the members of the therapeutic  team can plan suitable interventional programs such as SM education in order to have efficient results.

By considering educational barriers, we can explore suitable programming to overcome these obstacles. Also by exploiting the facilitating factors of SM, we can use them as motivating factors for SM and as basics of treatment. The therapeutic team could use this aspect in counseling and educational sessions. Thus, it is superior that effective family members participate in educational programs alongside patients to be aware of the procedure of the treatment. In fact, this action could motivate patients to continue their cooperation and their adherence to SM.

Conclusion

In summary, this study is the first research in the field of assessing the inhibitors and facilitators of SM among T2DM patients based on SOC and decisional balance constructs of the TTM. Patients with T2DM in action group because had higher mean duration years of disease, higher percentage of family history of T2DM and educated in relation SM than pre-action group; therefore, the action group was more successful in planning for SM, increasing awareness in field diabetes, perception SES and overcome on barriers of SM compared to pre-action group.
