Abstract
STUDY TYPE : Cross-sectional study using data from the 2014 follow-up of the CoDiab-VD cohort.
The current study describes diabetes self-management (DSM) profiles in adults using self-reported outcomes associated with the performance of diabetes care activities, and psychological adjustment to the condition. We used self-reported data from a community-based cohort of adults with diabetes (N= 316). We conducted clustering analysis on selected DSM self-reported outcomes (i.e., DSM behaviors, self-efficacy and perceived empowerment, diabetes distress and quality of life). We tested whether the clusters differed according to care delivery processes, socio-demographic and clinical variables. Clustering analysis revealed four distinct DSM profiles that combine high/low engagement in DSM, and good/poor psychological adjustment with the disease. The profiles are differently associated with variables of financial insecurity perceived, having an insulin treatment, having depression, and congruency of care received with the Chronic Care Model. The results could help health professionals gain a better understanding of the different realities of people living with diabetes, identify patients at risk of poor DSM-related outcomes, and lead to the development of profile-specific DSM interventions.
Kind of Data
Sample survey data [ssd] / Self-reported data collected from paper questionnaire
Unit of Analysis
The analysis unit is the individual.
Among the 519 participants recruited in 2011–2012, we sent the 2014 follow-up questionnaire to the 402 participants not lost to follow-up, and 339 participants returned the completed questionnaire (response rate 84.3%).

Sampling

Sampling Procedure
Pharmacies accepting to participate in the study recruited individuals with diabetes during six-week periods in 2011-12 and 2017.
At time of the first recruitment in 2011-12, the number of survey participants were 519. From this baseline number, the participants of the 2014 follow-ups were 339. Among those participants, 316 had no missing data for the variables of interest and were included in the present study.

Data Collection

Dates of Data Collection
Start End
2014-10-01 2015-01-31
Data Collection Mode
Paper questionnaire, self-administered.
Data were self-reported by the participants, who filled in the questionnaire at home and sent it back to the investigators.

Questionnaires

Questionnaires
The 2014 annual questionnaire is composed of two parts: 1) the core questionnaire, which is quite similar for each annual CoDiab-VD questionnaire, and 2) a thematic module on psychosocial aspects of diabetes, which is specific to the 2014 questionnaire.
All variables described hereafter were collected in the 2014 questionnaire and used in the present study.


Variables used for the identification of diabetes self-management profiles:

Diabetes self-management behaviors (Summary of Diabetes Self-Care Activities: healthy eating,
physical activity, self-monitoring of blood glucose and foot care)
Self-efficacy (Stanford diabetes-specific questionnaire)
Empowerment (Diabetes Empowerment Scale)
Diabetes distress (Problem Areas In Diabetes (PAID instrument)
Diabetes-specific quality of life (Audit of Diabetes Dependent Quality of Life, ADDQoL)


Variables used for the comparison of diabetes self-management profiles:


Sociodemographic characteristics:
-Age
-Gender
-Household size
-Difficulty paying bills
-Employment

Clinical variables:
-Diabetes type
-Disease duration
-Antidiabetic treatment
-HbA1c knowledge
-Anthropometric values:
----Weight
----Height
-Smoking
-Depression screening (two validated questions for the screening of depression)
-Comorbidities:
----List of following chronic diseases: heart disease (heart failure, valve disease, heart muscle disease), chronic lung disease (asthma, chronic bronchitis, emphysema), osteoporosis, osteoarthritis or arthritis; cancer or malignancy or lymphoma (with the exception of skin cancer), gastric or duodenal ulcer, depression, Parkinson’s disease, hypertension, hyperlipidaemia, other chronic condition.
-Health literacy

Process of care indicators (whether the process was received during the past 12 months):
-Glycated haemoglobin (HbA1c) check
-Eye examination by ophthalmologist
-Urine test for microalbuminuria
-Diabetic foot examination
-Lipid profile

Outcomes of care indicators:
-Patient assessment of diabetes care, congruence of care with the chronic care model
-(Patient Assessment of Care for Chronic Conditions, PACIC)

Data Processing

Data Editing
Data were checked first upon receipt of the questionnaires, for inconsistency (multiple check marks when only one allowed, incoherent numbers or between related questions); second, throughout the scanning process, for data entry; and last, by proofing the output Excel file obtained after the entry process.

OTHER PREOCESSING :
The clustering analysis was performed using self-reported data from the 316 participants who had no missing data on the variables used for the DSM profiles’ identification. First, we performed descriptive univariate analyses (i.e., frequency, percentages, mean scores and standard deviations). Successively, we converted variables’ scores used for cluster identification to standardized values since each instrument had different scales and units. These statistical procedures were applied on the average value of the diabetes distress variable (PAID-5, range 0 to 4), which was then rescaled for reporting to a range from 0 to 20 to ease the comparison with previous literature. To determine the number of clusters, we proceeded by visual examination of the dendrogram (agglomeration schedule) and looked at the stage of appearance of sudden large increase in the similarity measure between joined clusters. Then, to test the robustness of identified clusters, we compared two classification methods: agglomerative hierarchical procedure using Ward’s method and iterative partitioning using k-means method. We calculated a Cohen’s kappa coefficient to measure the level of agreement in the distribution of participants in the identified clusters between both methods. Finally, we tested whether the clusters differed according to socio-demographic, clinical and care delivery process variables using One-Way ANOVA for continuous variables and χ2 comparison for categorical variables. All analyses were conducted with SPSS statistical software 23.0.
