Understanding of hypo- and hyperglycemia by youngsters with diabetes and their parents

Blood Glucose Discrimination Training: The Role of Internal and External Cues

The effects of observing internal and external events on blood glucose (BG) discrimination were assessed in eight patients with type 1 diabetes using an intrasubject design. During baseline condition, participants estimated their BG, then measured and recorded it (feedback-only procedure) three times a day. Participants were then divided randomly into two groups. Both were submitted to internal cue (IC) and external cue (EC) training conditions in a balanced order, and then both cues were presented together in combined cues (CC) training conditions. Under IC, participants observed and recorded their symptoms before estimating BG. Under EC, they observed and recorded environmental events prior to BG estimation. In CC conditions, participants paid attention to both internal and external cues before the estimate–feedback routine. BG estimation accuracy improved after either IC or EC conditions. When the two types of cues were combined, only two participants improved their BG estimation accuracy. The remainder did not, probably because they had already attained high accuracy levels (ceiling effect).

Diabetes problem solving by youths with type 1 diabetes and their caregivers: measurement, validation, and longitudinal associations with glycemic control

OBJECTIVES

This article introduces a new measure of problem-solving skills of youths with type 1 diabetes (T1DM) and adult caregivers in correcting glycemic fluctuations.

METHODS

The Diabetes Problem Solving Interview (DPSI), a structured interview, was validated during a pilot study of a behavioral intervention. DPSI data and measures of diabetes management were obtained at baseline from 114 youths (ages 9-14.5) and 109 caregivers. Glycosylated hemoglobin (HbA(1c)) was measured quarterly over 9 months.

RESULTS

Results confirmed the psychometric adequacy of the DPSI. For caregivers, but not youths, low DPSI scores (indicating poor problem-solving skills) were significantly associated with worse HbA(1c) over 9 months.

CONCLUSIONS

The DPSI has clinical and research utility as a measure of diabetes problem-solving skills. Identification and targeted remediation of caregivers' deficient diabetes problem-solving skills or promotion of youths' utilization of these skills could possibly enhance glycemic control in youths with T1DM.

Psychometric properties and normative data for the parent version of the diabetes independence survey

The parent version of the Diabetes Independence Survey measures parents' perceptions of their children's mastery of 38 diabetes self-care skills. The instrument was administered to 648 parents of 622 children with insulin-dependent diabetes mellitus, ages 3 and 18 years, at seven different pediatric medical centers. Data confirming the internal consistency, interrater reliability, construct validity, and concurrent validity of the instrument are presented in this paper. Age-adjusted normative data for total scores on the instrument as well as item-by-item data on the ages at which mastery of each skill was reported by 25%, 50%, and 75% of parents also are discussed. The Diabetes Independence Survey can be used as a reliable, valid, and efficient research tool for assessing the growth and development of diabetes knowledge and skills among children and adolescents, and as a screening instrument and program evaluation tool for clinical purposes.

Symptom reporting in asthma patients and insulin-dependent diabetics

In this paper, results from two studies are presented. (1) Sixty-eight diabetics registered their blood glucose levels both as estimated and as measured and they indicated the intensity of 20 symptoms on a symptom checklist. Data were assessed twice a day over a 30-day period. During this period, blood glucose levels decreased slightly, the accuracy of blood glucose estimation improved, and for about half of the subjects specific symptoms could be identified, which covaried closely with blood glucose levels over time. (2) Fifty-three asthmatic patients monitored their peak flow each morning and evening over a period of 30 days. Before measuring peak flow, the patients estimated their peak flow and indicated the intensity of 28 symptoms specific for asthma. For about half of the sample, symptoms were identifiable, which correlated highly with measured peak flow. A substantial increase in the accuracy of estimated peak flow could be observed over time.

Problem solving anchored instruction about sick days for adolescents with diabetes

This study's hypotheses were that both shortly after instruction and after an 8-month follow-up, diabetic children taught via anchored instruction (AI), a format for problem solving, would outperform controls. Subjects were 81 9-15-year-old campers with insulin dependent diabetes who were randomly assigned to AI or control groups for two 45-min small group teaching sessions. Als viewed a video about a girl who mismanages her diabetes during intercurrent illness, and they were challenged to identify, define and solve her errors. Controls learned sick-day management via conventional direct instruction. At the end of the 2-week camp, AI and control groups' scores on factual knowledge were equal. AIs were more likely than controls at the end of the camp (0.75 vs. 0.54, P < 0.05) and 8 months later (0.59 vs. 0.38, P < 0.02) to provide a rationale for the use of remembered guidelines. Across all campers, this ability to link guidelines and their rationales was significantly correlated (r = 0.55, P < 0.01) with the number of self-management practices employed by campers who suffered an illness between the end of camp and the 8-month follow-up. Only one long-term behavioral difference between groups emerged: Als' parents shared in making most diabetes decisions on sick days, while controls' parents left more decision making to their children. AI appears at least as good as conventional teaching, and may better 'link' rules and reasons, perhaps aiding daily real-life problem solving.

Social support and health: a theoretical formulation derived from King's conceptual framework

This article describes the development and initial empirical testing of a theoretical formulation of social support, family, health, and child health derived from Imogene King's conceptual framework for nursing. A correlational design was used to test the formulation with 103 families who have children with diabetes mellitus. Three hypotheses were supported: parents' social support had a direct and positive effect on family health, parents' social support and child's social support were positively related, and illness factors had a direct and negative effect on child health. Both the supported and unsupported hypotheses are discussed in terms of the present substantive knowledge base and evidence of validity for King's framework. Direction for further theory development and research are identified.

Impact of blood glucose monitoring on diabetic control: obstacles and interventions

Despite frequent use in the management of diabetes mellitus, self-monitoring of blood glucose (SMBG) is not achieving its potential therapeutic impact. Among the behavioral factors which may interfere with the improvement of diabetic control through SMBG are noncompliance and inadequate utilization of obtained blood glucose data. This paper reviews the research concerning these issues, including estimates of the prevalence and clinical significance of each of these limiting factors and an evaluation of assessment and intervention strategies which have been investigated. The methodological problems encountered in attempts to demonstrate that SMBG behaviors affect diabetic control are discussed. Although the existing research literature provides very weak evidence linking SMBG behaviors and diabetic control, the author asserts that it is premature to conclude that such relationships cannot be established and maintained.

Symptomatic hypoglycaemia in childhood diabetes: a population-based questionnaire study

The occurrence of severe and mild hypoglycaemic attacks and their symptoms and signs were studied in 92 insulin-dependent diabetic children, 7-18 years old. A questionnaire was distributed to all families and they were interviewed by an experienced nurse. Severe attacks, for which the help of an adult was needed, were reported by 44% of the children during a 12-month period. Thirty-seven per cent of the attacks occurred in the mornings, most often attributed to extra physical exercise, but equally often without any obvious cause. They were more common in children with strict blood glucose control measured as HbA1c. Fast-acting carbohydrates, given by parents, relieved the attack in most children, but 15% needed a glucagon injection and 12% intravenous glucose. In all, 16% were admitted to hospital. Mild events occurred in 97% of the children, at least once per week in 53% of the children, and were not related to blood glucose control. They were often attributed to extra physical exercise and occurred mainly between breakfast and lunch. Initial symptoms were tremor and hunger; during the whole event tremor and sweating were most common. Parents noted pallor as the most common sign. The frequency of severe or mild attacks could not be correlated to the age of the child, duration of diabetes, daily dose or number of insulin injections.

Diabetes patient education: a health care provider perspective

Diabetes patient educa tion, a preventive health service, is an integral component of the overall program of care for the diabetic patient. Affecting both biomedical and psychosocial status, it may be analyzed through its knowledge- and behavior-based com ponents. Both are impor tant to the overall result, and each involves distinct provider knowledge and skills for successful, effec tive application. This application optimally in cludes a reproducible process involving a needs assessment, educational content planning, im plementation strategies, and appropriate evaluative methods. Familiarity with these concepts and tech niques will benefit the interested health care provider.

Innovations in behavioral medicine

The chapter begins with a brief history of the behavioral medicine movement along with an overview of contemporary activities in the field. Three subsequent sections review technical innovations in major areas of clinical behavioral medicine: treatment, health care delivery, and preventive health care. The final section describes the methodological characteristics of research in behavioral medicine, discusses the field in light of the psychosomatic medicine and behavior modification movements, and calls for a conceptual integration that is authentically behavioristic. Already the quality of research in behavioral medicine appears comparable to that of research in behavior therapy. Even so, when viewed in terms of contemporary methodological desiderata, most of the work is fairly unimpressive. Possibly needed are "hybrid" experimental approaches in which the inferential power of intrasubject phase manipulations and between-subject outcome comparisons are combined. There is good reason to believe that behavioral medicine will follow the historical course of behavior therapy/modification, not the course of psychosomatic medicine. Behaviorally knowledgeable psychologists can become major service providers in liaison with well-informed medical practitioners. Some potentially deleterious influences on the behavioral medicine movement are (inevitable) mentalistic and dualistic thinking and a retreat toward psychosomatic medicine. Field behaviorism as an organizing schema can, in principle, serve as a safeguard against such untoward influences.
