Behavior therapy for families of adolescents with diabetes: maintenance of treatment effects.

OBJECTIVE: This study reports 6- and 12-month follow-up for the families of adolescents with diabetes who participated in a trial of Behavioral-Family Systems Therapy (BFST). RESEARCH DESIGN AND METHODS: A total of 119 families of adolescents with type 1 diabetes were randomized to 3 months of treatment with either BFST, an education and support (ES) group, or current therapy (CT). Family relationships, adjustment to diabetes, treatment adherence, and diabetic control were assessed at baseline, after 3 months of treatment, and 6 and 12 months later. This report focuses on the latter two evaluations. RESULTS: Compared with CT and ES, BFST yielded lasting improvements in parent-adolescent relationships and diabetes-specific conflict. Delayed effects on treatment adherence emerged at 6- and 12-month follow-ups. There were no immediate or delayed effects on adolescents' adjustment to diabetes or diabetic control. CONCLUSIONS: BFST yielded lasting improvement in parent-adolescent relationships and delayed improvement in treatment adherence, but it had no effect on adjustment to diabetes or diabetic control. A variety of adaptations to BFST could enhance its impact on diabetes outcomes.

Psychosocial therapies in diabetes: report of the Psychosocial Therapies Working Group.

OBJECTIVE: To review key advances in the behavioral science literature related to psychosocial issues and therapies for persons with diabetes, to discuss barriers to research progress, and to make recommendations for future research. RESEARCH DESIGN AND METHODS: Key findings from the literature on psychosocial research in diabetes are reviewed separately for children and adults. Specific issues covered include psychosocial adjustment and psychiatric disorders, neurocognitive functioning, quality of life, and psychosocial therapies. Barriers that must be addressed to allow research in this area to progress are discussed. Recommendations are then made concerning high-priority areas for advancing research in the field. CONCLUSIONS: A substantial amount of behavioral science research has demonstrated that psychosocial factors play an integral role in the management of diabetes in both children and adults. Research has also shown the efficacy of a number of psychosocial therapies that can improve regimen adherence, glycemic control, psychosocial functioning, and quality of life. More research in this area is needed to develop psychosocial intervention programs for specific patient populations and to demonstrate the cost-effectiveness of these approaches.

Validation of a structured interview for the assessment of diabetes self-management.

OBJECTIVE: The authors developed and validated a semi-structured interview; the Diabetes Self-Management Profile (DSMP), to measure self-management of type 1 diabetes. The DSMP includes the following regimen components: exercise, management of hypoglycemia, diet, blood glucose testing, and insulin administration and dose adjustment. RESEARCH DESIGN AND METHODS: Families of youths with type 1 diabetes (n = 105) who were entering a controlled trial of intensive therapy (IT) versus usual care (UC) were administered the DSMP Analyses assessed the reliability and validity of the DSMP, including its associations with HbA1c and quality of life. RESULTS: The DSMP total score has adequate internal consistency (Cronbach's alpha 0.76), 3-month test-retest reliability (Pearson correlation, r = 0.67), inter-interviewer agreement (r = 0.94), and parent-adolescent agreement (r = 0.61). DSMP total scores (r = -0.28) and 3 subscales correlated significantly with HbA1c (diet [r = -0.27], blood glucose testing [r = -0.37], and insulin administration and dose adjustment [r = -0.25 ]). Adolescents' reports of self-management did not differ from parental reports. Higher DSMP scores were associated with more favorable quality of life for mothers and youths. CONCLUSIONS: The DSMP is a convenient measure that yields a reliable and valid assessment of diabetes self-management. Compared with extant similar measures, the DSMP is more strongly correlated with HbA1c.

Validation of measures of parents' preoperative anxiety and anesthesia knowledge.

UNLABELLED: Parents' anxiety about their children's anesthesia may adversely affect the children's outcomes and compromise the quality of informed consent. Studies of these issues have been limited by the lack of validated measures of parental anxiety and knowledge surrounding anesthesia. In the present study, we evaluated psychometric properties of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and the Standard Anesthesia Learning Test (SALT) among 85 parents who participated in an evaluation of the effects of a videotape about pediatric anesthesia. The results supported the internal consistency, test-retest reliability, and concurrent validity of both instruments and documented the equivalence of two forms of the SALT. Factor analysis supported the previously demonstrated factor structure of the APAIS, further confirming its construct validity. We conclude that the APAIS and SALT are reliable and valid measures of parental anxiety and knowledge of pediatric anesthesia that can be used for clinical and research purposes. IMPLICATIONS: This study verified the reliability and validity of two questionnaires for measuring parents' knowledge and anxiety about pediatric anesthesia. These questionnaires can be used in further research on factors affecting parental anxiety and knowledge before their children's surgery.

Social validity of support group and behavior therapy interventions for families of adolescents with insulin-dependent diabetes mellitus.

Compared the social validity of behavior therapy vs. support group interventions for reduction of parent-adolescent conflict among families of adolescents with diabetes. Families were randomized to 10 sessions of an Education and Support group (ES) or 10 sessions of Behavioral Family Systems Therapy (BFST). We compared participants' social validity ratings of BFST and ES using the Treatment Evaluation Questionnaire (TEQ). Mean TEQ scores were significantly more positive for BFST than ES and, for 13 of 20 items, BFST was rated significantly more positively by parents and/or adolescents. Adolescents rated ES less positively than did parents. Fathers' responses reflected fewer differences between ES and BFST. Results extend previous research on BFST and confirm its superiority over ES for targeting family conflict.

[Continuous arteriovenous hemofiltration in the management of patients with shock and multiorgan insufficiency syndrome].

Spontaneous continuous arterio-venous hemofiltration (CAVH) is a blood purification system based on blood filtration through capillary hemofilters without pumps, using the arterio-venous pressure gradient for blood perfusion. In 2-nd Department of Surgery of Medical University of Gdańsk in the years 1989-1996 we introduced CAVH 13 times in 6 women and 7 men, aged from 17 till 79 years. We used this technique to maintain fluid balance in anuric patients needing parenteral fluids. Due to circulatory and respiratory insufficiency all patients needed catecholamines infusion and controlled respiration. In 7 patients acute renal failure was caused by septic shock and in 6 patients by shock after severe multiorgan injuries. The CAVH therapy lasted from 3 till 16 days. The stabilisation of hemodynamic and renal parameters was observed in all patients. 3 patients died of cranio-cerebral injuries and 2 due to longlasting septic shock induced by necrotic pancreatitis. In all patients CAVH was required to remove the excess water given as carrier in total parenteral nutrition. Experience with 13 cases has shown the CAVH technique, to be particularly useful in patients with vascular instability or severe fluid overload. The above method which needs no technical investment is simple to handle.

Deviation from developmentally appropriate self-care autonomy. Association with diabetes outcomes.

OBJECTIVE: Treatment of IDDM in youth emphasized balancing children's self-care autonomy with their psychological maturity. However, few data exist to guide clinicians or parents, and little is known about correlates of deviations from this ideal. RESEARCH DESIGN AND METHODS: In this cross-sectional study, IDDM self-care autonomy of 100 youth was assessed using two well-validated measures. Three measures of psychological maturity (cognitive function, social-cognitive development, and academic achievement) were also collected for each child. Composite indexes of self-care autonomy and of psychological maturity were formed, and the ratio of the self-care autonomy index to the psychological maturity index quantified each child's deviation from developmentally appropriate IDDM self-care autonomy. Based on these scores, participants were categorized as exhibiting constrained (lower tertile), appropriate (middle tertile), or excessive (higher tertile) self-care autonomy. Between-group differences in treatment adherence, diabetes knowledge, glycemic control, and hospitalization rates were explored. RESULTS: Analysis of covariance controlling for age revealed that the excessive self-care autonomy group demonstrated less favorable treatment adherence, diabetes knowledge, hospitalization rates, and, marginally, glycemic control. Excessive self-care autonomy increased with age and was less common among intact two-parent families but was unrelated to other demographic factors. CONCLUSIONS: The findings indicate caution about encouragement of maximal self-care autonomy among youth with IDDM and suggest that families who succeed in maintaining parental involvement in diabetes management may have better outcomes.

Associations among teen-parent relationships, metabolic control, and adjustment to diabetes in adolescents.

Extended previous studies of adolescents with insulin-dependent diabetes mellitus (IDDM) that have implicated family conflict as a correlate of poor adaptation to the disease and inadequate diabetic control. Families of 115 adolescents with IDDM completed the Parent-Adolescent Relationship Questionnaire (PARQ) and the Teen Adjustment to Diabetes Scale (TADS) and recent glycohemoglobin levels were retrieved from medical records for 82 patients. PARQ scores of families of adolescents with IDDM were similar to those of a healthy normative group. Multiple regression analysis showed that a PARQ scale measuring family communication and conflict resolution skills was a strong predictor of the IDDM outcome variables, suggesting that these families could derive health and behavioral benefits from an intervention that improves parent-adolescent communication skills. Controlled trials of such interventions are needed.

Parental and professional estimates of self-care independence of children and adolescents with IDDM.

OBJECTIVE: To report the results of a survey of 490 parents of children with insulin-dependent diabetes mellitus (IDDM) regarding the children's mastery of 38 diabetes-care skills. Parental responses are contrasted with those of a previous survey in which 229 diabetes professionals estimated ages at which typical children with IDDM master the same skills. RESEARCH DESIGN AND METHODS: Parents were recruited at five pediatric endocrinology clinics with a response rate of 88.9%. RESULTS: For 33 of 38 skills, professionals' median mastery age estimates exceeded, by greater than or equal to 1 yr, the median ages that parents reported skill mastery by their estimates, children. Despite the parent-professional disagreement about mastery-age their survey responses yielded substantial agreement about the order of mastery of specific skills. The data also revealed two profiles of comparative results. For many items, parents reported earlier skill mastery, but parental and professional estimates eventually converged during adolescence. These skills consisted of rote, motoric acts, or more complex tasks for which errors yield relatively certain aversive consequences. For other skills, more professional estimated skill mastery among adolescents than did parents. These skills required substantial organization and self-regulation by the adolescent, involved treatment components for which the aversive consequences of errors are deferred and uncertain, or they were skills infrequently required of most patients with IDDM. CONCLUSIONS: The parent-professional discordance revealed by this survey illustrates the importance of clear specification of treatment responsibilities, careful monitoring of self-care competence, and periodic reeducation of children with IDDM.

Use of blood glucose data by families of children and adolescents with IDDM.

OBJECTIVE: Prospective evaluation of the use of blood glucose test results for treatment actions by families of youth with IDDM. RESEARCH DESIGN AND METHODS: Forty-seven patients with IDDM used reflectance meters with memory for SMBG for 28 days. Parents kept weekly diaries of six types of uses of SMBG data. We collected SMBG data from the reflectance meters, HbA1 and serum fructosamine assays, and measures of behavioral factors that could affect use of SMBG data. RESULTS: Families recorded a mean of 4.85 data-based actions during the 28-day study, and 74% of the families reported at least one such action. Fifty percent of recorded actions consisted of management of hypoglycemia and, among the remainder, only 18% were anticipatory, proactive actions. Partial correlation analysis showed that families with more frequent use of SMBG data had less parent-child conflict about diabetes, more diabetes knowledge, and better overall treatment adherence. Use of SMBG data was unrelated to objective indices of the need for treatment adjustments or to diabetic control. CONCLUSIONS: Most families made active use of their SMBG data, but few of these actions were proactive. Behavioral factors were stronger predictors of family use of SMBG data than were objective indices of the need for treatment adjustments. The results illustrate the need for further research on use of SMBG data and methods to enhance its impact on diabetic control.

Diabetes mellitus in the transition to adulthood: adjustment, self-care, and health status.

A cross-sectional study of health and adjustment among 18 to 22-year-old patients with insulin-dependent diabetes mellitus (IDDM) is reported. Objectives were to examine coping with IDDM in this age group; to identify predictors of health status, treatment adherence, and health care use; and to provide a retrospective evaluation of the persistence of IDDM-specific adjustment from earlier through later adolescence. Multiple validated measures, interviews of independent informants, and biochemical assays were used to assess psychological, behavioral, and metabolic status. Patients and parents completed a retrospective measure of the patient's adjustment to IDDM during earlier adolescence. Findings (n = 81) indicated: (1) normal rates of general psychopathology but some evidence of poorer adjustment to IDDM relative to other age groups, (2) poor diabetic control and high incidence of microalbuminuria, (3) specific factors associated differentially with treatment compliance, health care use, diabetic control, and microalbuminuria among late adolescents, and (4) evidence that poor adjustment to IDDM in earlier adolescence persists into the transition to adulthood. The findings imply that late adolescents with IDDM are at risk of various unfavorable behavioral and health outcomes and that adjustment to the disease during earlier adolescence may be a predictor of subsequent health-related behavior and health status. A longitudinal study is needed to confirm these findings.

Review of Survware from CompuStat software.

Survware is a simple program which permits the user to analyze the responses from multiple choice questionnaires and surveys of 2-50 questions. It is inexpensive when compared with a complete statistical package, but the limitation to frequency data may result in the need to purchase additional software. This program is most likely to be useful to users who regularly collect survey data and who do not need inferential statistical analysis of those data.

Review of Q-FAST interactive testing system.

The administration and scoring of paper and pencil measures present a host of logistical problems to clinicians, researchers and educators who rely heavily on these techniques. In addition to the expense of producing and reproducing these materials, the completed measures must be scored, the results must be reduced and recorded and the data must be analyzed. The introduction of human error at any of these steps may compromise the reliability of the obtained data and obstruct its valid interpretation. The Q-FAST computerized testing system is a software package which could improve the efficiency of collection, scoring and analysis of data obtained through such procedures.

Fear of hypoglycemia in children and adolescents with diabetes.

Extended a study of diabetic adults which showed that fear of hypoglycemia is common and may affect diabetic control. That study evaluated the psychometric properties of the Hypoglycemic Fear Survey (HFS), an instrument designed to measure fear of hypoglycemia. The present study evaluated the psychometric properties of the HFS with diabetic youth. The HFS was completed by 128 Ss on arrival at a diabetes summer camp, by 127 Ss at the end of the 7-day camp, and by 74 Ss 12 weeks after camp. The results support the internal consistency and test-retest reliability of the HFS with this age group. Factor analytic and multiple regression techniques support the construct validity of the scale. HFS scores enhanced prediction of diabetic control. The HFS appears to be useful as a research tool with children and adolescents, although cross-validation is needed before clinical use can be justified.

Survey of diabetes professionals regarding developmental changes in diabetes self-care.

There are no empirically obtained data defining appropriate developmental expectations for the acquisition of self-care independence by children with insulin-dependent diabetes mellitus. This study surveyed diabetes professionals about their estimates of ages at which children typically master 38 diabetes skills. The 229 survey respondents represented a broad range of professions and clinical settings and had extensive experience as diabetes professionals. Mean mastery age estimates were less than 14 yr for the 38 skills assessed. Responses to each item were variable among respondents, with a mean SD of 2.1 yr in estimated mastery ages for all items. Estimated mastery ages were below the age ranges recommended by the American Diabetes Association for 14 of 20 comparable skills. Physicians generally expected the diabetes skills to be mastered at later ages than did nurses or other health-care professionals. There were no other consistent response patterns related to respondent characteristics, i.e., years of clinical experience, employment setting, current patient load, or method of survey distribution.

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.
