A longitudinal study of life events and metabolic control among youths with insulin-dependent diabetes mellitus.

In a study of school-age children with new-onset insulin-dependent diabetes mellitus (IDDM), life stress, metabolic control (glycosylated hemoglobin), and psychiatric and psychosocial variables were assessed repeatedly for up to 6 years. Life stress was defined as the number of undesirable life events and extent of life change necessitated by all life events. In univariate longitudinal analyses, total life change units were related to metabolic control, with a trend for number of undesirable events to be associated with metabolic control. In multivariate analyses, metabolic control was related to life change units, whether the glycosylated hemoglobin was in the 1st year of IDDM, IDDM duration, and the diagnosis of pervasive noncompliance with medical regimen. The relationship of life stress to metabolic control among youths with diabetes is significant but clinically modest and may be partially mediated by serious noncompliance with the medical regimen.

Relation of stressful life events to metabolic control among adolescents with diabetes: 5-year longitudinal study.

Objective: To determine the relation of stressful life events to metabolic control. Design: We interviewed adolescents with Type 1 diabetes (n = 132; average age at enrollment = 12 years) annually for 5 years. Measures: Each year we administered measures of stressful life events, psychological distress, and self-care behavior. We downloaded data from blood glucose meters, and obtained measures of metabolic control (hemoglobin A1c) from medical records. Results: Using longitudinal growth curve modeling, stressful life events predicted greater psychological distress, poorer self-care behavior, and worse metabolic control in both cross-sectional and longitudinal (lagged) analyses. Cross-sectionally, many of these relations were stronger among older than younger adolescents. Self-care behavior partly mediated this association. Conclusion: Stressful life events are related to poor metabolic control—especially for older adolescents. A primary mechanism appears to be a lack of good self care.

Gay-related stress and emotional distress among gay, lesbian and bisexual youths: A longitudinal examination.

The longitudinal relations between gay-related stress (i.e., gay-related stressful events, negative attitudes toward homosexuality, and discomfort with homosexuality) and emotional distress (i.e., anxious symptoms, depressive symptoms, and conduct problems) were examined at 3 assessment periods (baseline, 6 months, and 12 months) among 140 gay, lesbian, and bisexual (GLB) youths. Although some findings were consistent with the hypothesis that stress would be associated with subsequent distress among GLB youths, the larger number of nonsignificant relations and the presence of relations between distress and subsequent gay-related stress indicate that the hypothesis was unsupported. The authors discuss the potential reasons for the lack of hypothesized relations and offer suggestions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development of interpersonal understanding: A longitudinal and comparative study of normal and disturbed youths.

Using an interview procedure, levels of interpersonal understanding were assessed for 17 behaviorally and emotionally disturbed boys and were compared longitudinally, across 3 assessments at 2- and 4-yr intervals, with those of 17 better-adjusted male peers matched for age, race, SES, and WISC-R IQ. Ss were in Grades 1–6 at Time 1, 3–8 at Time 2, and 7–22 at Time 3. Results suggest that the sequence of progression through levels of interpersonal understanding was the same for both disturbed and normal samples but that the developmental trend of trouble Ss lagged behind that of the higher-functioning group. However, longitudinal follow-up results suggest that the developmental lag of the disturbed Ss was diminishing with time. An exploratory study conducted during Time 3 suggested that relatively low levels of interpersonal understanding were related to the self-reported use of physical and avoidant strategies to resolve conflicts. Results are considered in the context of theoretical relations between thought and action. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does psychiatric disorder predict violent crime among released jail detainees? A six-year longitudinal study.

Examined whether jail detainees with schizophrenia, major affective disorders, alcohol or drug use disorders, or psychotic symptoms (hallucinations and delusions) are arrested more often for violent crimes 6 yrs after release than are detainees with no disorders. Trained interviewers assessed 728 randomly selected male jail detainees using the National Institute of Mental Health Diagnostic Interview Schedule and then obtained follow-up arrest data for 6 yrs. Neither severe mental disorder nor substance abuse or dependence predicted the probability of arrest or the number of arrests for violent crime. Ss with symptoms of both hallucinations and delusions had a slightly higher number of arrests for violent crime, but not significantly so. These findings held even after controlling for prior violence and age. The findings do not support the stereotype that mentally ill criminals invariably commit violent crimes after they are released.

Restrained eating and BMI: A longitudinal study among adolescents.

Objective: Although restrained eating is believed to increase overeating and weight in the long term, the opposite has also been found: Heavy individuals are more likely to diet. The objective of the current study was to test both pathways for adolescents. Design: A longitudinal model was used to explore the bidirectional associations between restrained eating and body mass index (BMI). Main Outcome Measures: At 3 annual waves, restrained eating and BMI were obtained from both older (M age 15.2 years old) and younger (M age 13.4 years old) adolescent boys and girls who were sibling pairs in 404 Dutch families. Results: Structural equation modeling showed that BMI predicted restrained eating more consistently than the other way round. The results remained the same when analyzed by sex, age, socioeconomic status, and overeating tendency. Thus, in our general survey of adolescents restrained eating did not seem to be a successful weight loss strategy, nor did it consistently predict weight increase. Conclusion: Positive associations between restrained eating and BMI should mainly be interpreted in the sense that higher BMI predicted more restrained eating.

Predicting prospective episodes of depression in patients with panic disorder: A longitudinal study.

This study used a naturalistic, longitudinal study to examine predictors of the emergence of major depression among 90 nondepressed patients with panic disorder who were followed for a 2-yr period. 24% of the sample experienced a major depressive episode during the study period. Adequacy and type of medication treatment were not associated with decreased risk. Past history of major depression was associated with a greater risk for a prospective episode. The degree of assertiveness, presence of comorbid generalized anxiety disorder, and severity of agoraphobia were each significant predictors of the occurrence of depression when considered alone and when the influence of past history of depression was statistically controlled. The implications of these findings for the clinical management of patients with panic disorder are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Burnout and inequity among human service professionals: A longitudinal study.

In a composite sample of human service professionals (N?=?245), longitudinal relations across 1 year were tested between equity in the professional–recipient relationship and burnout (i.e., emotional exhaustion, depersonalization, and reduced personal accomplishment). The 1st research question was whether inequity influenced burnout across time. The 2nd research question was whether longitudinal relations between equity and burnout were curvilinear, as predicted by equity theory. The results confirmed that inequity affects the central component of burnout (i.e., emotional exhaustion) and that this relation is curvilinear. Feeling more deprived and feeling more advantaged resulted in higher future emotional exhaustion levels. No indication was found for a longitudinal relation between inequity and depersonalization. A synchronous relation was found suggesting that personal accomplishment influences equity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Kidney morphological changes in relation to long-term renal function and metabolic control in adolescents with IDDM

OBJECTIVE: To investigate the impact of HIV infection on the prevalence, incidence and short-term prognosis of squamous intraepithelial lesions (SIL), in a prospective study with 1-year follow-up. METHODS: Between 1993 and 1995, 271 HIV-positive and 171 HIV-negative women at high risk of HIV infection were recruited, 365 (82.6%) of whom completed the 1-year follow-up. The women underwent a Papanicolaou smear test at inclusion and at 6 and 12 months. Human papillomavirus (HPV) was detected at inclusion by Southern blot and PCR. RESULTS: The SIL prevalence ranged from 7.5% for HIV-negative to 31.3% for HIV-positive women with CD4 cell counts < 500 x 10(6)/l (P < 0.001). Other factors associated independently and significantly with SIL prevalence were HPV-16, 18, 33 and related types, HPV-31, -35, -39 and related types, lifetime number of partners, younger age, past history of SIL and lack of past cervical screening. The SIL incidence ranged from 4.9% in HIV-negative women to 27% in HIV-positive women with CD4 cells < 500 x 10(6)/l (P < 0.001). Progression from low- to high-grade SIL during follow-up was detected in 38.1% of HIV-positive women with CD4 cells < or = 500 x 10(6)/l but in no HIV-negative nor HIV-positive women with CD4 cells > 500 x 10(6)/l. HPV-16, 18, 33 and related types were also associated with higher incidence of SIL and progression from low- to high-grade SIL. CONCLUSION: HIV-induced immunodeficiency is associated with high prevalence, incidence and persistence/progression of SIL. A pejorative influence of HIV infection without marked immunodeficiency is less clear. HIV-positive women with SIL may thus benefit from early treatment when a useful immune response is still present.     

Relations among mothers' expressivity, children's effortful control, and their problem behaviors: A four-year longitudinal study.

Longitudinal relations between mothers' expressivity, children's effortful control, and their problem behaviors were examined when children (N = 181) were 6.5-10 years old (T2) and again 2 (T3) and 4 (T4) years later. Mothers reported on their expression of positive and negative dominant emotion. Mothers and teachers reported on children's effortful control and externalizing and internalizing problem behaviors. In structural equation models, variables exhibited consistency over time. Further, the relation between mothers' expressivity (positive minus negative dominant emotion) at T2 and children's externalizing problems at T4 was mediated by T3 effortful control. The same process of mediation was significant for teacher- but not mother-reported internalizing problems. The results provide one explanation for how emotion-related socializing behaviors influence children's problem behaviors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mothers' teaching strategies and children's effortful control: A longitudinal study.

Findings on the relation of maternal verbal teaching strategies to children's effortful control (EC; i.e., self-regulation) are limited in quantity and somewhat inconsistent. In this study, children's EC was assessed at 18, 30, and 42 months (ns = 255, 229, and 209, respectively) with adults' reports and a behavioral measure. Mothers' verbal teaching strategies were assessed while the mother and child worked on a task together. Children's general vocabulary also was measured. In a structural panel model taking into account prior levels of constructs and correlations within time, as well as the relations of EC and teaching strategies to children's vocabulary, socioeconomic status, age, and sex of the child, 18-month EC positively predicted mothers' 30-month cognitive assistance and questioning strategies and negatively predicted 30-month maternal directive strategies. In addition, high 30-month EC predicted greater 42-month maternal cognitive assistance and fewer directive strategies. Thus, mothers' teaching strategies were predicted by individual differences in self-regulatory skills, supporting potential evocative child effects on mothers' teaching strategies.

Problem drinking and depression among DWI offenders: A three-wave longitudinal study.

Longitudinal data collected at 3 occasions of measurement from a convicted driving-while-intoxicated sample (n?=?302) were used to study the interrelations between problem drinking and depressive symptomatology. Time intervals between occasions of measurement were approximately 9 months. Cross-lagged latent variable models indicated that higher levels of depression at Time 1 were significantly associated with lower levels of problem drinking at Time 2. Similarly, higher levels of problem drinking at Time 1 were significantly associated with lower levels of depression at Time 2. However, the direction of effects for the cross-lagged coefficients was reversed for the Time-2–Time-3 relations. Higher levels of depression at Time 2 were significantly associated with higher levels of problem drinking at Time 3, and higher levels of problem drinking at Time 2 were associated with higher levels of depression at Time 3. The results are interpreted to reflect a biphasic process. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological functioning among mothers of children with insulin-dependent diabetes mellitus: A longitudinal study.

Mothers of children with newly diagnosed insulin-dependent diabetes mellitus (IDDM) were assessed repeatedly over a period of 6 years in order to determine the psychological correlates of managing this chronic illness. Both maternal depression and overall emotional distress after the 1st year of the IDDM increased slightly with illness duration and were also influenced by other factors. Mothers' adjustment shortly after their children were diagnosed with IDDM was a strong predictor of their long-term emotional symptomatology. However, mothers' symptoms over time were not related to medical aspects of IDDM (i.e., the extent of the children's metabolic control, number of rehospitalizations, or their compliance with the medical regimen) and were also unrelated to the levels of depression or anxiety reported by their children. Mothers generally found it easier to cope with the IDDM the longer their children had the illness. However, the degree to which mothers perceived the IDDM to be bothersome or difficult to manage at any given point in time was associated with their overall levels of emotional distress.

Cognitive patterns and major depressive disorder: A longitudinal study in a hospital setting.

Assessed the cognitive patterns of individuals suffering from unipolar major depressive disorder, episodic and nonpsychotic type, shortly after admittance to an inpatient psychiatric facility and again shortly before discharge. In addition to the depressive group, a nondepressed psychiatric and a nondepressed normal group were administered the same measures (Hopelessness Scale, the Dysfunctional Attitude Scale, and the Attributional Style Questionnaire) at comparable points in time. In contrast to the concept of a traitlike depressive cognitive style that persists beyond remission of the current depressive episode, the depressives showed dramatic changes on all of the cognitive measures as their symptoms abated. Results suggest that unipolar major depressive disorder, episodic and nonpsychotic type, may be heterogeneous with respect to cognitive patterns. Whereas a sizeable group of Ss suffering from this disorder exhibited the hypothesized depressive cognitive profile during the depressive episode, others did not.

Rate and predictors of divorce among parents of youths with ADHD.

Numerous studies have asserted the prevalence of marital conflict among families of children with attention-deficit/hyperactivity disorder (ADHD), but evidence is surprisingly less convincing regarding whether parents of youths with ADHD are more at risk for divorce than are parents of children without ADHD. Using survival analyses, the authors compared the rate of marital dissolution between parents of adolescents and young adults with and without ADHD. Results indicated that parents of youths diagnosed with ADHD in childhood (n = 282) were more likely to divorce and had a shorter latency to divorce compared with parents of children without ADHD (n = 206). Among a subset of those families of youths with ADHD, prospective analyses indicated that maternal and paternal education level; paternal antisocial behavior; and child age, race/ethnicity, and oppositional-defiant/conduct problems each uniquely predicted the timing of divorce between parents of youths with ADHD. These data underscore how parent and child variables likely interact to exacerbate marital discord and, ultimately, dissolution among families of children diagnosed with ADHD.

Pubertal growth, sexual maturation, and final height in children with IDDM. Effects of age at onset and metabolic control

The effects of free ampicillin, microencapsulated ampicillin anhydrate (MEAA) and antibiotic-free microspheres on the cell-mediated immune response in Balb/c mice were measured by lymphoproliferation assay, delayed-type hypersensitivity (DTH) and cytokine production. Injection into mice for seven consecutive days with equivalent subcutaneous doses of ampicillin, MEAA or placebo microspheres did not produce any consistent change in lymphocyte proliferation nor did it affect DTH responses or interleukin-2 production. Although the production of interleukin-4 in mice treated with ampicillin or MEAA increased compared with the control mice, this increase was not statistically significant. These results indicate that ampicillin and MEAA have similar effects on cell-mediated immunity in mice.     

Psychiatric symptoms and syndromes among adolescent children of parents with lithium-responsive or lithium-nonresponsive bipolar disorder

OBJECTIVE: The purpose of this pilot study was to describe the initial course of psychiatric illness in the adolescent children of parents with bipolar disorder who were divided into two groups on the basis of their response to long-term lithium monotherapy. METHOD: Proband parents met Research Diagnostic Criteria for bipolar illness and predetermined criteria for a clear response or nonresponse to lithium prophylaxis. All adolescent offspring were interviewed by a blinded interviewer using the Schedule for Affective Disorders and Schizophrenia for School-Age Children, and final diagnosis was made by blinded consensus. RESULTS: Psychiatrically ill children of lithium-responsive parents tended to have affective disorders that remitted and followed a recurrent course. Psychiatrically ill children of lithium-nonresponsive parents, however, manifested a broad range of psychopathology, had high rates of comorbid illnesses, and experienced nonremitting affective illnesses. CONCLUSIONS: These results suggest that family history and course of illness are important factors to consider in the diagnosis and pharmacological treatment of affective disorders.     

A longitudinal study of family obligation and depressive symptoms among Chinese American adolescents.

The purpose of this 2-year, 3-wave longitudinal study of Chinese American adolescents was to examine how family obligation behaviors and attitudes change over time; how gender, nativity, and birth order predict these trajectories; and whether family obligation relates to depressive symptoms. Findings suggest that family obligation behaviors decreased over the 2-year period but that family obligation attitudes were stable. Moreover, foreign-born adolescents reported higher levels of family obligation behavior than U.S.-born adolescents, and firstborn adolescents reported higher family obligation attitudes than laterborn adolescents. There were no gender differences in family obligation behaviors or attitudes. The findings also suggest that initial higher levels of family obligation were associated with subsequently fewer depressive symptoms. Finally, changes in family obligation behaviors related to changes in depressive symptoms over time such that increasing family obligation behaviors related to decreasing depressive symptoms. The results highlight the importance of understanding the role of family obligation to Chinese American adolescents’ mental health. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Workload, control, and social support effects on serum lipids: A longitudinal study among apparently healthy employed adults.

The authors investigated the direct and interactive effects of the job demand– control–support (JDC-S) model’s components on subsequent changes in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides (TRI) separately for male and female employees. In contrast to all 14 past studies on these relationships, the authors used a longitudinal design. Study participants (N = 1,137, 66% men) were all apparently healthy employees who underwent a routine health check at 2 points in time (Time 1 and Time 2) about 22 months apart. In these analyses, the authors controlled for the Time 1 level of each criterion and for other confounders. Most of the direct and moderating effects found did not support the predictions of the JDC-S model; this finding is in agreement with the majority of past cross-sectional studies. The authors did not find any evidence supporting the existence of a reverse causation for either of the components of the JDC-S model. The authors suggest that serum lipids may not be a physiological mechanism mediating the effects of the JDC-S model on atherosclerotic diseases.
