“…In line with the previous study in Greece [18], the DEPS-R scale had acceptable internal consistency, suggesting that this tool is reliable for Greek T1DM patients. Our results also confirmed a significant positive association of DEPS-R score with BMI (≤0.001), TTD (p ≤ 0.001), HbA1c (p < 0.01) and TIR (p < 0.05), while it was also revealed that a higher BMI and TIR were independent predictors of a positive DEPS-R screen, implying more DE behaviors.…”

“…CFA was performed using the AMOS program, version 22. In line with an earlier study with Greek adults [ 18 ], item number 8 (I make myself vomit) had almost zero variance, which did not allow computation of covariance matrices and fit indices. Item 8 was also highly skewed to zero, implying that its exclusion would not affect the DEPS-R total score; hence, this item was not included in the CFAs.…”

“…The Greek version of DEPS-R [ 18 ] was administered to identify EDs and unhealthy weight loss practices in the study population in the 4 weeks before the completion of the questionnaire. The questionnaire consists of 16 items, and the responses are recorded on a 6-point Likert scale, ranging from 0 = never to 5 = always, where the higher the score of each patient, the greater the risk of ED.…”

“…The Italian version of the DEPS-R provided initial support for the validity and reliability of the instrument [ 9 ], and the Norwegian version showed adequate psychometric properties when used with adults [ 10 ]. Apergi and colleagues (2020) reported that the Greek version of the DEPS-R is a valid, self-administered T1DM-specific screening tool for adults [ 18 ].…”

“…The present study aims: (a) to validate the factor structure of the Greek version of DEPS-R using confirmatory factor analysis (CFA), which was not reported in the initial Greek study; (b) to investigate the reliability and convergent validity of the Greek version of the DEPS-R in a sample different from that of Apergi and colleagues (2020) [ 18 ]; and (c) to compare a single factor DEPS-R model with multiple factor models.…”

The Diabetes Eating Problem Survey-Revised (DEPS-R) in a Greek Adult Population with Type 1 Diabetes Mellitus: Model Comparison Supporting a Single Factor Structure

Type 1 diabetes mellitus (T1DM) patients occasionally develop disordered eating behaviors, leading to insulin manipulation without medical consultation, targeting to achieve weight control. In clinical practice, the Diabetes Eating Problem Survey-Revised Version (DEPS-R) questionnaire has been used to evaluate eating disorders in T1DM patients. This study was conducted to validate the factor structure of the Greek version of DEPS-R using Confirmatory Factor Analysis (CFA), to investigate its reliability and convergent validity in Greek T1DM adults and to compare a single factor DEPS-R model with multiple factor models. Participants were 103 T1DM adults receiving insulin, who responded to DEPS-R. Their anthropometric, biochemical and clinical history data were evaluated. The sample presented good glycemic control and 30.1% scored above the established DEPS-R cut-off score for disturbed eating behavior. CFA results revealed that the data fit well to the factor models. The DEPS-R scale had good reliability and was positively linked to BMI, HbA1c, total daily dose and time in range. Model comparison supported the superiority of the 1-factor model, implying that Greek clinicians and practitioners might not have to consider individualized treatment based on various scores across different subscales but they can adopt a single DEPS-R score for an easy and efficient screening for disordered eating.

Background Insulin restriction and/or omission in Type 1 Diabetes Mellitus (T1DM) is a risky disordered eating behaviour increasingly reported in the literature. Most existing literature has focused on females with T1DM. Previous research, however, suggests disordered eating behaviours are over-represented in males with T1DM versus males without T1DM. This systematic scoping review sought to summarise the existing literature to contribute to the development of an understanding of males’ misuse of insulin for weight and/or shape control. Methods A systematic scoping review methodology was used. We searched six electronic databases. Eligible articles were quantitative, qualitative, or mixed methods empirical studies with primary data on the restriction and/or omission of insulin for weight and/or shape control among males, written in English from database inception to December 2021. Results A final sample of 56 articles was included (48 quantitative, six qualitative and two mixed methods). Where it was reported to occur, estimates of the behaviour ranged from 5 to 75% in females and 1.4% to 76% in males. In 12 studies examining sex differences, only three reported higher prevalence in females. Understandings about the behavioural context of the behaviour were hampered by lack of qualitative research (n = 4 studies). Conclusion Despite common preconceptions, this disordered eating behaviour appears to occur similarly in males and females. The findings shed light on areas for future research, including aetiology in males and the need for longitudinal and qualitative research. Clinical recommendations include being alert to the possibility of this behaviour in males with Type 1 Diabetes Mellitus and the need for health professionals to use open-ended questions to explore current and past deliberate restriction and/or omission of insulin among their patients.

Purpose People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients’ perspectives on screening questionnaires. This paper reports qualitative analyses of patients’ perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding. Research design and methods 15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen. Results The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5–10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants. Conclusion The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R. Level of evidence V – qualitative study.
