Not Applicable
Completed
Conditions
Diabetes Mellitus, Type 2
Interventions
Behavioral: Guilty feelings
Registration Number
NCT04387045
Lead Sponsor
Francisco Carlos López Marquez
Brief Summary

The purpose of this study is to determine the effect of measured and induced negative feelings on glucose, tumor necrosis factor alpha, and cortisol levels in healthy participants and participants with type 2 diabetes mellitus.

Detailed Description

Depression and Diabetes are two pathologies that are frequently comorbid. Stress and negative thoughts are part of both. The biological correlates of psychological and emotional life are not yet fully clarified, so in this study we wonder about the association between tumor necrosis factor alpha, cortisol, and peripheral glucose levels with depression stress, measured negative thoughts, and induced guilt.This is a randomized intervention study. At baseline, participants complete the Beck Depression Inventory, the Automatic Negative Thoughts Scale (ATQ-N), and the Perceived Stress Scale (PSS-14). The intervention consists of a written task about situations that involved feelings of guilt or neutral situations. Saliva and dextrostix samples are taken before the 20-minute written task, at the end, dextrostix and saliva samples are performed again, finally a blood sample is taken.

Primary Outcome Measures
NameTimeMethod
Salivary cortisolSample collection is two times during a single day for each participant, with an interval of 20 minutes. Since it will be measured in fasting, it will take place between 8:00 a.m. and 9:00 a.m.

mg/dL

Glucose levelsSample collection is two times during a single day for each participant, with an interval of 20 minutes. Since it will be measured in fasting, it will take place between 8:00 a.m. and 9:00 a.m.

mg/dL

Salivary Tumor Necrosis Factor alphaSample collection is two times during a single day for each participant, with an interval of 20 minutes. It will take place between 8:00 a.m. and 9:00 a.m.

Secondary Outcome Measures
NameTimeMethod
Perceived stressThis variable is measured in a single day and represents the week prior to the study.

Perceived stress scale (PSS-14), range 0-40.Higher scores indicating higher perceived stress. Scores ranging from 0-13 would be considered low stress. Scores ranging from 14-26 would be considered moderate stress. Scores ranging from 27-40 would be considered high perceived stress.

DepressionThis variable is measured in a single day and represents the week prior to the study.

Beck's Depression Inventory, range 0-63. Higher number indicating more severe depression.

Negative thoughtsThis variable is measured in a single day and represents the month prior to the study.

Automatic negative thoughts scale (ATQ-N), range 0-90. Higher scores mean a worse outcome (more negative thoughts).
