Testing a Self-Determination Theory Process Model for Promoting Glycemic Control Through Diabetes Self-Management.

A longitudinal study tested the self-determination theory (SDT) process model of health behavior change for glycemic control within a randomized trial of patient activation versus passive education. Glycosylated hemoglobin for patients with Type 2 diabetes (n=159) was assessed at baseline, 6 months, and 12 months. Autonomous motivation and perceived competence were assessed at baseline and 6 months, and the autonomy supportiveness of clinical practitioners was assessed at 3 months. Perceptions of autonomy and competence were promoted by perceived autonomy support, and changes in perceptions of autonomy and competence, in turn, predicted change in glycemic control. Self-management behaviors mediated the relation between change in perceived competence and change in glycemic control. The self-determination process model fit the data well.

Social networks and aggressive behavior: Peer support or peer rejection?

Studied social networks and aggressive behavior in school in 2 cohorts of boys and girls in the 4th and 7th grades (N?=?695). Measures of social networks yielded convergent findings. Highly aggressive subjects (both boys and girls) did not differ from matched control subjects in terms of social cluster membership or in being isolated or rejected within the social network. Peer cluster analysis and reciprocal "best friend" selections indicated that aggressive subjects tended to affiliate with aggressive peers. Even though highly aggressive children and adolescents were less popular than control subjects in the social network at large, they were equally often identified as being nuclear members of social clusters. Aggressive subjects did not differ from matched control subjects in the number of times they were named by peers as "best friend," nor did the two groups differ in the probability of having friendship choices reciprocated by peers.

Role of manipulation in infants' responses to invariant properties of objects.

Hypothesized that manipulation would enhance 1-yr-old infants' attention to and detection of structural invariants more than nonstructural invariants. In Study 1, 16 Ss were familiarized with 2 series of objects, one in which texture remained invariant while color changed and the other in which pattern remained invariant while shape changed. Within each series, Ss were tested for differential responsiveness to 2 new objects, one with the familiar characteristic and the other with a novel one. In Study 2, 12 Ss were familiarized with another 2 series of objects, one in which shape remained the same while pattern varied and the other in which color remained the same while texture varied. Data from the two studies are consistent in that the structural invariants were more clearly differentiated than the nonstructural invariants. Results of Study 3, in which 12 Ss were familiarized with objects encased in plastic boxes, suggest that Ss in Studies 1 and 2 were using haptic information about shape and texture to enhance their differentiation of objects along those lines.

Auditory–visual responsiveness in full-term and preterm infants.

Compared older preterm and full-term infants in their response to objects in a dynamic multimodal context. In Study I, 67 12-wk-old full-term infants and 29 preterm infants (mean age 90 days) served as Ss. After familiarization with a silent moving object, full-term Ss recognized the object when it was stationary. When sound accompanied the moving object during familiarization, full-term Ss showed increased attention to the object but no subsequent recognition of that object. Neither high- nor low-risk preterms, at a comparable conceptional age, recognized the objects under any condition, but the low-risk preterms did show greater attention to the moving objects with sound. In Study II, 43 preterm Ss were tested approximately 6 mo after their estimated term date. The performance of the low-risk preterms was the same as that of full-terms; that is, through differential responding, they demonstrated association of an object and sound. In contrast, the high-risk preterms showed no differential looking. Thus both low- and high-risk preterms showed less differential responding than did normal full-terms at 3 mo, but at 6 mo only the high-risk preterms were different from the full-terms. Results suggest that the high-risk preterms are at a disadvantage for learning about the dynamic and multimodal aspects of their environment.

Family involvement in school and low-income children's literacy: Longitudinal associations between and within families.

Longitudinal data from kindergarten to 5th grade on both family involvement in school and children's literacy performance were examined for an ethnically diverse, low-income sample (N = 281). Within families, increased school involvement predicted improved child literacy. In addition, although there was an achievement gap in average literacy performance between children of more and less educated mothers if family involvement levels were low, this gap was nonexistent if family involvement levels were high. These results add to existing evidence on the value of family involvement in school by demonstrating that increased involvement between kindergarten and 5th grade is associated with increased literacy performance and that high levels of school involvement may have added reward for low-income children with the added risk of low parent education. As such, these results support arguments that family involvement in school should be a central aim of practice and policy solutions to the achievement gap between lower and higher income children.

Personality and the predisposition to engage in risky or problem behaviors during adolescence.

Longitudinal data from a representative sample of 1,978 Black and White adolescents were used to examine the role of personality in multiple risk or problem behaviors. Results indicate that covariation among diverse behaviors (educational underachievement, delinquent behavior, substance use, sexual behavior) can be adequately modeled by a single higher order factor, and that impulsivity and avoidance coping serve as generalized risk factors for involvement in these behaviors. Whereas none of the personality variables examined explained change in problem behaviors once established, avoidance coping prospectively predicted involvement among a subgroup of adolescents with little or no prior involvement. Results suggest that dysfunctional styles of regulating emotions and emotionally driven behaviors are core features of risky or problem behaviors during adolescence.

"The association between emotional upset and cardiac arrhythmia during daily life": Correction to Carels et al. (2003).

Reports an error in the original article by R. A. Carels et al (Journal of Consulting & Clinical Psychology, 2003[Jun], Vol 71[3], 613-618). On page 615, Lines 18, 20, 22, of Table 1, the data in the rows that read "Tachycardia in min per hr," "Repetitive PVCs per hr," and "PVCs per hr" are incorrectly reported in the n and % columns. They should have been reported in the M and SD columns. The corrected table is provided. (The following abstract of this article originally appeared in record 2003-00756-023.) Ventricular arrhythmia exhibits considerable within-subject variability that cannot be attributed to clinical status alone. This investigation examined the extent to which cardiac arrhythmia was associated with psychological and physical factors assessed during the hour preceding arrhythmic or nonarrhythmic activity. Approximately twice hourly, 46 patients randomly completed a diary assessing mood and physical symptoms during 24-hr electrocardiographic monitoring. Greater negative emotion was associated with increased arrhythmia. Additionally, greater negative emotion was significantly associated with increased arrhythmia among participants in a low left ventricular ejection fraction group (LVEF). However, this relationship between negative emotion and arrhythmia was not... (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Work-family conflict and burnout among practicing psychologists.

Research has found that men and women psychologists experience burnout differentially depending on the work setting. A total of 497 psychologists responded to a survey designed to replicate this finding and to investigate the role of work-family conflict in contributing to this difference. Results failed to replicate gender differences in levels of burnout according to work setting. In general, the overall pattern of results was the same for men and women. Findings indicated that family support was important for well-being at work and that conflict between work and family domains was associated with burnout. Mediational models indicated that work-family conflict and family-work conflict can help researchers understand the process by which resources or demands in work and family domains influence burnout at work.

Community services for rape survivors: Enhancing psychological well-being or increasing trauma?

This research examined how contact with the legal, medical, and mental health systems affects rape survivors' psychological well-being. Although community services may be beneficial for some victims, there is increasing evidence that they can add trauma, rather than alleviate distress (termed secondary victimization). This study examined how secondary victimization affects rape survivors' posttraumatic stress (PTS) symptoms. Adaptive and snowball sampling were used to recruit a sample of 102 rape survivors. Victims of nonstranger rape who received minimal assistance from either the legal or medical system, and encountered victim-blaming behaviors from system personnel, had significantly elevated levels of PTS. This high-risk group of rape survivors had PTS levels significantly higher than all other victims in this study, including those who did not seek community assistance postrape. However, for these high-risk rape survivors, receiving sustained mental health services after these negative experiences was associated with a significant decrease in PTS.
