Assessment and treatment of problem behavior occasioned by interruption of free-operant behavior

The current study describes the assessment and treatment of the problem behavior of 3 individuals with autism for whom initial functional analysis results were inconclusive. Subsequent analyses revealed that the interruption of free-operant behavior using "do" requests (Study 1) as well as "do" and "don't" requests (Study 2) occasioned problem behavior. Initially, treatment involved differential and noncontingent reinforcement without interruption. To make the intervention more sustainable in the natural environment (where interruptions are unavoidable), a two-component multiple-schedule arrangement was used to progressively increase the period of time in which ongoing activities would be interrupted. During generalization sessions, the intervention was applied across a variety of contexts and therapists.     

The Significance of Employment for Chronic Stress and Psychological Distress among Rural Single Mothers

Considerable research has found elevated levels of stress and psychological distress among single mothers. However, little research has addressed the relevance of employment for stress processes in this population, and few studies have focused on links between employment, stress, and mental health among single mothers living in rural areas. Based on a probability sample of 508 single mothers age 18-39 living in rural Northern New England, this study: (1) documents variations in chronic stress and psychological distress for employed and unemployed single mothers, (2) considers the extent to which different forms of chronic stress mediate or explain the employment-distress relationship, and (3) examines whether employment status modifies associations between chronic stress and psychological distress. Findings indicated that rural single mothers who were employed reported significantly less financial stress, childcare stress, and rural residence stress, relative to mothers who were not employed, independent of variety of other factors. Employed mothers also experienced significantly less psychological distress which was partially mediating by their lower financial stress. However, there was also a statistical interaction between employment status and financial stress such that the harmful effect of financial stress on well-being was greater for employed women. Implications of the findings are discussed.     

Somatic responses in behavioral inhibition

In the present study, skin conductance responses (SCRs) were measured postdecision and prefeedback in a go/no-go (GNG) task in which participants used response feedback to learn when to respond or not to respond to numeric stimuli. Like somatic markers in gambling tasks and somatic reactions to error monitoring in choice reaction time tasks, SCR patterns distinguished between correct and incorrect trials over time. These somatic reactions were disrupted by a reversal of GNG contingencies, and they were facilitated by pretraining of the stimulus—response mappings. In all cases, however, the somatic reactions appeared to be a product of competent decision making rather than a contributor to performance. Differential somatic responses to good and bad choices appear to be a robust and fairly general phenomenon, but researchers should be cautious in assuming that the somatic responses contribute to performance.     

Laying it on thin: analogical cue frequency in the manipulation of choice

Persuasive analogies consist of linguistic cues that invite audiences to represent a problem in terms of an analog and to make choices compatible with this manipulated representation. The authors explore how the frequency of linguistic cues moderates analogical bias in choice behavior. Participants read versions of a managerial decision scenario differing in the number of sports (e.g., game plan) or family (e.g., parent company) idioms used to describe situational attributes and then chose between analogically consistent and inconsistent response options. Analogies consisting of an intermediate number of cues elicited higher rates of analogically consistent responding than those of higher and lower cue frequency. When explaining their responses, participants referred to the sports or family analogies most often to rationalize rejecting the analogically consistent response option after reading high cue frequency versions. These findings indicate that there are lower and upper boundaries to a persuasive analogy's optimal cue frequency.     

For-profit/nonprofit differences in center-based child care quality: Results from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development

In secondary analyses of National Institute of Child Health and Human Development Study of Early Child Care and Youth Development data, multiple indicators of quality (caregiver wages and turnover; child/staff ratio; caregiver education and professionalism; positive caregiving) were compared between child care centers by sector (for-profit/nonprofit) and subsector (for-profit independent/chain, nonprofit church/nonchurch) at multiple points from infancy through prekindergarten. Nonprofit centers evidenced higher caregiver wages and education at most ages and better quality child/staff ratios, turnover, caregiver professionalism, and positive caregiving for toddlers and preschoolers. Subsector differences in preschool classrooms were more complex. In general, quality was higher in nonprofit non-religiously affiliated centers, intermediate in nonprofit religiously affiliated and for-profit independent centers, and lower in for-profit chains, but differences were not found on every indicator or between every group. Further, for-profit chain status predicted lower quality positive caregiving, controlling for family characteristics, staff, and structural quality, at 54 months, but not 36 months. Results support and extend prior research by controlling for family characteristics. Policy implications regarding supply- and demand-side quality-improvement strategies that address market competition and parent choice across subsectors are discussed.     

Eating disorder pathology among overweight treatment-seeking youth: clinical correlates and cross-sectional risk modeling

Preliminary research suggests that pediatric overweight is associated with increased eating disorder pathology, however, little is known about which overweight youth are most vulnerable to eating disorder pathology. We therefore investigated 122 overweight treatment-seeking youth to describe eating disorder pathology and mental health correlates, and to identify psychopathological constructs that may place overweight youth at increased risk for eating disorder pathology. Youth participated in a comprehensive assessment of eating disorders, mood and anxiety disorders, general psychopathology, and risk variables involving semi-structured clinical interviews and self- and parent-report questionnaires prior to the initiation of weight-loss treatment. Ten youth met criteria for an eating disorder, and over one-third endorsed recent binge eating. Eating disorder pathology was associated with depressive and anxious symptoms (p's<0.001). Structural equation modeling indicated increased negative affect, teasing experience, and thin-ideal internalization, and decreased perfectionism were associated with increased eating disorder pathology. Findings corroborate earlier work indicating that eating disorder pathology is elevated and clinically significant in overweight treatment-seeking youth, bolstering the need for mental health assessment of such individuals. Cross-sectional modeling proposed key variables that relate to eating disorder pathology in overweight treatment-seeking youth, which following prospective replication, may inform the development of effective interventions for overweight and eating disorders.     

Social support and prognosis in patients at increased psychosocial risk recovering from myocardial infarction.

OBJECTIVE: To compare the impact of network support and different types of perceived functional support on all-cause mortality or nonfatal reinfarction for patients with a recent acute myocardial infarction (AMI). DESIGN: Participants were recruited from the Enhancing Recovery in Coronary Heart Disease (ENRICHD) trial; 2,481 AMI patients with depression or low social support were randomized to a cognitive-behavioral intervention or to a usual care control group. Data collection for certain measures of social support was limited: 2,466 participants completed the ENRICHD Social Support Inventory; 2,457 completed the Perceived Social Support Scale; 1,296 completed the Social Network Questionnaire; and 707 completed the Interpersonal Support and Evaluation List, Tangible Support subscale. Patients also completed the Beck Depression Inventory and were followed for up to 4.5 years. MAIN OUTCOME MEASURE: Time to death or nonfatal reinfarction. RESULTS: Over the follow-up period, 599 patients (24%) died or had a nonfatal AMI. Survival models controlling age, sex, race, socioeconomic status, smoking, antidepressant use, and a composite measure of increased risk revealed that higher levels of perceived social support were associated with improved outcome for patients without elevated depression but not for patients with high levels of depression. Neither perceived tangible support nor network support were associated with more frequent adverse events. CONCLUSION: AMI patients should be assessed for multiple dimensions of perceived functional support and depression to identify those at increased psychosocial risk who may benefit from treatment.     

Romantic Relationships and Health: An Examination of Individuals’ Perceptions of their Romantic Partners’ Influences on their Health

This study examines individuals’ perceptions of the impact their significant others have on their health and the extent to which these perceptions are associated with relationship quality and actual health. Two-hundred and ten participants (105 U.S. couples; mean age = 24.93) completed measures of their relationship quality and health along with an open-ended measure asking them to indicate how they felt their partner influenced their health. Results indicated that participants perceived their romantic partners to be primarily positive health influences, women believed their partners were more influential than did men, and eating and physical activity behaviors were believed to be most affected by partners. Participants’ relationship quality and health were associated with their reports of their perceived partners’ health influences. The research described in this report was supported by an award to Charlotte Markey from Rutgers University.     

Adolescents' performance on the Iowa Gambling Task: implications for the development of decision making and ventromedial prefrontal cortex

Healthy adolescents (79 girls, 66 boys), ages 9-17, completed the Iowa Gambling Task (IGT; A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) as well as working memory (digit span) and behavioral inhibition (go/no-go) tasks. Cross-sectional age-related changes were seen on all 3 tasks. Gender differences were seen in IGT deck preference and attentional variables (i.e., go/no-go hit rate and forward digit span). After age, gender, and general intellectual abilities were controlled for, IGT performance was not predicted by working memory or behavioral inhibition scores. Findings suggest that the ventromedial prefrontal cortex or its connections are functionally maturing during adolescence in a manner that can be distinguished from maturation of other prefrontal regions. Development of these functions may continue into young adulthood.
