Abstract

AIMS: To report the prevalence and correlates of affective and anxiety disorders, depressive affect and diabetes distress over time. METHODS: In a non-interventional study, 506 patients with Type 2 diabetes were assessed three times over 18 months (9-month intervals) for: major depressive disorder (MDD), general anxiety disorder (GAD), panic disorder (PANIC), dysthymia (DYS) (Composite International Diagnostic Interview); depressive affect [Center for Epidemiological Studies-Depression (CES-D)]; Diabetes Distress Scale (DDS); HbA(1c); and demographic data. RESULTS: Diabetic patients displayed high rates of affective and anxiety disorders over time, relative to community adults: 60% higher for MDD, 123% for GAD, 85% for PANIC, 7% for DYS. The prevalence of depressive affect and distress was 60-737% higher than of affective and anxiety disorders. The prevalence of individual patients with an affective and anxiety disorder over 18 months was double the rate assessed at any single wave. The increase for CES-D and DDS was about 60%. Persistence of CES-D and DDS disorders over time was significantly greater than persistence of affective and anxiety disorders, which tended to be episodic. Younger age, female gender and high comorbidities were related to persistence of all conditions over time. HbA(1c) was positively related to CES-D and DDS, but not to affective and anxiety disorders over time. CONCLUSIONS: The high prevalence of comorbid disorders and the persistence of depressive affect and diabetes distress over time highlight the need for both repeated mental health and diabetes distress screening at each patient contact, not just periodically, particularly for younger adults, women and those with complications/comorbidities.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In a community sample of type 2 diabetes patients, the point prevalence of diabetes distress (18.0%) is substantially higher than that of major depressive disorder (10.7%).

    “In comparative analyses of a community sample of patients with type 2 diabetes, we showed a substantially higher point-prevalence of diabetes distress (DD) (18.0%) than of major depressive disorder (MDD) (10.7%);”
  • High depressive affect in patients with diabetes is often not clinical depression but instead diabetes-related emotional distress.

    “Previous studies have shown that most patients with diabetes who display high levels of depressive affect are not necessarily clinically depressed 1, 2; instead, they experience high levels of emotional distress stemming from concerns and worries associated with their diabetes and its management 1,3.”
  • Diabetes distress is significantly related to HbA1c and several disease management measures, whereas MDD and depressive affect are not significantly related to these variables in controlled analyses.

    “the analyses indicated a significant relationship between diabetes distress, HbA1c and several disease management measures, whereas no significant relationships were found in controlled analyses among MDD, depressive affect and these variables 1,3.”
  • High DD, once it occurs, is a relatively persistent condition.

    “We reported previously that the point prevalence of high DD was about 18% of patients in our diverse community sample, and that high DD, once it occurs, is a relatively persistent condition (3).”
  • Diabetes-related distress is more chronic than major depressive disorder in patients with diabetes.

    “diabetes-related distress, or significant negative emotional reactions to the diagnosis of diabetes, threat of complications, self-management demands, unresponsive providers, and/or unsupportive interpersonal relationships, has been found to be far more common, more chronic, and more closely related to diabetes self-care and glycemic control than MDD (5–7).”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • GAD prevalence increase is given two different values

    Minor

    One Results passage says GAD was 123% higher than community adults, but another says it was 122% higher. These are conflicting statements about the same comparison.

  • Abstract overstates the conditions associated with female gender

    Minor

    The abstract says female gender was related to persistence of all conditions, whereas the discussion specifies depressive symptoms, diabetes distress and panic disorder-not all the conditions assessed.

  • Prevalence comparisons differ between the abstract and results

    Minor

    The abstract gives increases of 123% for GAD and 7% for dysthymia, while the results give 122% and 6%, respectively, for the same comparisons.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-09-28.
