What Diagnostic Devices Do: The Case of Blood Sugar Measurement

Diagnostic devices do more than just passively register facts. They intervene in the situations in which they are put to use. The question addressed here is what this general remark may imply in specific cases. To answer this question a specific case is being analysed: that of the blood sugar measurement device that people with diabetes may use to monitor their own blood sugar levels. This device not only allows the patients concerned to better approach normal blood sugar levels, but alters what counts as normal in the first place. Using the device may shift people's attention away from their physical sensations towards the numbers measured, but it may also help them to increase their own physical self-awareness. Self-monitoring finally (something that the devices have made possible) makes patients less dependent on professionals, but it requires them to engage in self-disciplining and binds them to the outcomes of their measurement activities: their own blood sugar levels.     

The effectiveness of cognitive behavioral group intervention on depression and anxiety in patients with type II diabetes

IntroductionDepression and anxiety are important risk factors for diabetes and high blood pressure.ObjectiveThis study investigated the effectiveness of the Cognitive-Behavioral Group Intervention for Diabetes Disease (CBGI-DD) in reducing depression and anxiety in female patients with type 2 diabetes (T2D).MethodThe CBGI-DD program includes 12 weekly 2.5 h sessions, spread weekly over the course of 3 months. The present study was semi-experimental and controlled, with assessments at pre-test and post-test. It included diagnostic criteria for the diagnosis of T2D in the patient's medical records by a diabetes specialist. Participants (62 female volunteers aged 25 to 75 years) were randomly allocated to a control or test group. Both groups responded to the Second edition of the Beck Depression Inventory (BDI-II) and the Beck Anxiety Inventory (BAI) before (pretest) and immediately after the intervention (posttest). Participants in the test group received CBGI-DD (from April up to the end of September 2018) at Mashhad Diabetes Center. The control group received only medical care during this period.ResultsAn analysis of covariance showed that compared to the control group, the test group had a significant reduction in anxiety and depression from pre-test to post-test (p < 0.05). It was compared post-test scores between the two groups, controlling for pre-test scores.ConclusionThe CBGI-DD program seems to be effective in reducing anxiety and depression in female patients with T2D. However, further research exploring the potential for long-term improvements in depression and anxiety is needed.     

Eating behaviors and emotional distress are predicted by treatment and adverse outcome in patients with type 2 diabetes

Depression and anxiety are hightly prevalent among patients with Type 2 Diabetes (T2D), however not commonly related to outcomes, treatment and comorbidities. Eating behaviors could also have an implication. To evaluate the relation between mood and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D we conducted this exploratory cross sectional study in a population from Mexico. Hospital Anxiety and Depression Scale and the Three Factor Eating Questionnaire Revised 21 (TFEQ-R21) were correlated with age, gender, blood pressure, treatment and comorbidities (nephropathy, neuropathy, retinopathy and cardiopathy). Multi-linear regression models and 2^k factorial analyses were conducted. Sixty-one patients (31 male) 55 years old (SD 13) with at least 5 years of T2D were included. Anxiety correlated with depression (r = 0.25, p < 0.05). Gender (women) (std B 0.026, p < 0.001), insulin therapy (std B 0.3, p = 0.11), systolic blood pressure (std B 0.263, p = 0.02) and cardiovascular disease (std B 0.232, p = 0.035) predicted depression. Insulin therapy had a positive effect in cognitive restraint. (std B 0.32, p = 0.001). Age (std B 0.37, p = 0.003) and systolic blood pressure (std B 0.237, p = 0.048) predicted positively emotional eating (not previously published). 2^k factorial analyses proved additive interaction between complications and insulin therapy with depression. This study supports the relation between mood disorders and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D and the additive interaction between factors and mood disorders.     

Maternal distress in the context of their child’s type 1 diabetes: exploring the role of adaptive maternal emotion regulation on child outcomes

Parents of children with Type 1 diabetes (T1D) experience high levels of distress, which may negatively impact child functioning. However, little is known about mechanisms that may buffer the adverse impact of parental distress. The current study explored the possible buffering role of maternal adaptive cognitive emotion regulation (CER) for the relationship between maternal distress and child psychological functioning. Forty-three children with T1D (8–15 years) completed measures assessing trait anxiety and depressive symptoms. Their mothers reported on general distress, illness-related parenting stress, and adaptive CER. Maternal illness-related parenting stress (but not general distress) was significantly associated with child psychological functioning. No buffering role for maternal adaptive CER was observed. As the current study is rather preliminary, future research using other methods to examine maternal adaptive CER, and examining other parental variables that may buffer against the negative impact of parental distress is warranted.     

The development of violence from age 8 to 61

The main aim of this study is to investigate the development of violence from childhood to adulthood. In the Cambridge Study in Delinquent Development (CSDD), 411 London males have been followed up from age 8 to 48 in interviews, and from age 10 to 61 in criminal records; 19% were convicted for violence. There was a surprising amount of violence committed at older ages (40–61). The number of violence convictions was similar at ages 10–20, 21–39, and 40–61. There was considerable continuity in violent offending from ages 10–20 to 40–61. There was also continuity in self-reported violence from ages 15–18 to 43–48, and violence convictions were related to self-reported violence at all ages. The most important childhood risk factors for violence convictions were high daring or risk-taking, low verbal intelligence, a disrupted family, harsh parental discipline, high hyperactivity, and large family size. The extent to which these risk factors predicted violence at ages 40–61 was noteworthy. The “integrated cognitive antisocial potential (ICAP)” theory was proposed to explain the development of violence, and methods of preventing violence, targeting childhood risk factors, were reviewed.     

Illness perception clusters and relationship quality are associated with diabetes distress in adults with Type 2 diabetes

This report aims to augment what is already known about emotional distress in Type 2 diabetes, by assessing the predictive value of illness perception clusters and relationship quality on four subcategories of Diabetes Distress.162 individuals with Type 2 diabetes responded to a postal questionnaire assessing demographics, depression, diabetes distress, illness perceptions and relationship quality. Long-term blood glucose was retrieved from participants’ General Practitioner. Three illness perception clusters emerged from the data, capturing three subgroups of participants sharing similar illness perception schemas. Regression analyses were performed across each diabetes distress subscale, with demographics, illness perception clusters, and relationship variables entered into three blocks. Covariates explained 51.1% of the variance in emotional burden, 41% of the variance in regimen-related distress, 20% of the variance in interpersonal distress, and 8.6% of the variance in physician-related distress. Cluster membership was strongly associated with emotional burden, regimen-related distress, and to a lesser degree interpersonal distress, but was not associated with physician-related distress. Relationship quality most strongly predicted regimen-related distress. Illness perception schemas and interpersonal issues influence emotional adjustment in diabetes. This study provides direction for the content of a novel approach to identifying and reducing diabetes distress in people with Type 2 diabetes.

Self-appraisal and coping in out-patients with chronic disease

Self-appraisal, coping efforts, muscle function, and activity and severity of disease were examined in out-patients with rheumatoid arthritis, osteoarthrosis or diabetes mellitus. Factor analysis of a 31-item self-appraisal and coping questionnaire yielded eight factors (self-appraisal, acceptance, minimization, planful problem-solving, avoidance, persistence, attribution of responsibility, and support seeking). For the factors of avoidance, minimization, and persistence, as well as for measures of activity and severity of disease, significant differences between the diagnostic groups were found. For patients with rheumatic arthritis, hierarchical regression analysis indicated disease duration to be associated with acceptance and with attribution of responsibility, and disability measures to be associated with self-appraisal. For patients with osteoarthrosis, they showed disability in muscle function to be associated with avoidance, and more negative self-appraisal as well as lower levels of support seeking to be associated with long disease duration. Results are discussed in terms of structural and adaptive defence forms and of adherence to a coping model ("medical model") which tends to foster acceptance and dependency.     

A general index of self-reported sleep: the sleep quotient

Utilizing multiple sleep measures, a practice common to virtually all sleep assessments, poses problems both for statistical analyses in the form of inflated Type I error rate and for interpretation by the inability to specify general sleep change. A sleep quotient (SQ) is proposed that appears to overcome these problems. The paper presents archival norms for self-report sleep data, demonstrates the use of these norms in transforming novel data to standardized units, and casts the standardized score in the form of an intelligence quotient, now called a SQ, with a mean of 100 and a standard deviation of 15. Previously published data are reanalyzed by use of SQ scores, methods of interpreting SQ data are demonstrated, and advantages of SQ analyses are described. The SQ appears to be a valid, useful composite sleep index permitting the measurement of general sleep.
