During the COVID-19 pandemic, the success of major non-pharmaceutical interventions, such as quarantine orders, has depended upon robust rates of citizens' adherence to protocols. Thus, it is critical to public health for research to illuminate factors that affect compliance with contagion-mitigating practices. Previous research has examined sociodemographic factors and aspects of psychological distress as correlates of adherence to public health guidelines.

In a modern world saturated with cellphone-related stimuli, surprisingly little is known about their psychological effects. A small number of previous studies have found global distracting effects of cellphone rings on cognitive performance in undergraduate students. However, moment-to-moment reactions to cellphone sounds have not been investigated, nor have physiological changes that might accompany the cognitive effects.

College students face consistent cognitive demands and often get insufficient and/or irregular sleep. The current study investigated associations of sleep duration and sleep variability with attentional performance. Sleep duration variability was expected to moderate the association between duration and cognitive functioning.

Emerging adults use text messaging as a principal form of social communication, day and night, and this may compromise their sleep. In this study, a hypothetical model was tested linking daytime and nighttime text message use with multiple sleep characteristics. Subjective and objective measures of texting and sleep were utilized to assess 83 college students over a seven-day period during an academic term.

Research on co-rumination has investigated its relationship with internalizing symptoms, but few studies have addressed underlying maladaptive cognitive-affective processes that may play an important role in the maintenance of this relation. This study examines if Young's schema domains mediate the relation between co-rumination and depression in a community sample of non-clinical young adults. Participants completed the Co-Rumination Questionnaire, Young Schema Questionnaire-L3, and Teate Depression Inventory.

Adolescents' and emerging adults' social interactions increasingly revolve around cellphone use, but little research has investigated the psychological properties of cellphone interactions. The current study explored co-rumination via cellphone; that is, the use of cellphone functions to excessively communicate about problems or negative feelings. Face-to-face co-rumination and co-rumination via cellphone were examined as potential moderators of the association between perceived interpersonal stress and psychosocial well-being (i.

Objectives: To investigate the role of control beliefs in the relationship between SES and health.

Methods: Two different aspects of perceived control - contingency beliefs (locus of control) and competence beliefs (self-efficacy) - were examined in relation to subjective SES and physical health outcomes (subjective health, functional impairment, chronic health problems, and acute health symptoms) in a diverse sample of undergraduates (N=231).

Results: Low self-efficacy was directly associated with poorer health outcomes and mediated the relationship between low SES and health, whereas locus of control did not.

Asthma is one of the most prevalent chronic illnesses among children in the United States and it disproportionately affects members of minority groups living in low-income and urban environments. In these environments, illness-related stressors are often experienced alongside a variety of family and social stressors, and parents may carry significant additional caregiving responsibilities over and above their child's asthma management. Participants in the current study included 23 girls and 22 boys, all diagnosed with asthma and living in low-income, urban neighborhoods; 85% of participants were members of ethnic minority groups.

Children with asthma living in urban environments are at risk for experiencing internalizing problems and difficulties at school due to social context and health-related stressors. Parent confidence and participation in the school and children's attitudes about school were explored in association with children's depressed mood and school anxiety. Forty-five parent-child dyads were recruited from urban community health centers.

Children with asthma living in urban environments are at risk for experiencing anxiety by virtue of both social context and health-related stressors. Although the use of active coping strategies is generally associated with more optimal psychosocial functioning, there is evidence that active coping is less helpful in response to uncontrollable or severe stress. Expectations that one can fix a problem that is uncontrollable or insurmountable may create distress.

Asthma is a disease of significant social magnitude that disproportionately affects children from minority and low-income backgrounds. Poor asthma management is one of the leading causes for high morbidity and mortality rates. In addition to conventional medications, many parents use complementary and alternative medication (CAM) to treat their child's asthma symptoms.

Objective: The combined contribution of neonatal, perinatal, and maternal health, demographic, environmental, and family psychosocial factors to early onset asthma and wheezing in a healthy birth cohort was examined.

Methods: Participants included 1,158 ethnically and socioeconomically diverse parents of 2- and 3-year olds who completed mailed questionnaires.

Results: Asthma and wheezing prevalence was 8.

This paper presents a conceptual model including examples of risk and resource factors associated with indices of school-related asthma morbidity (eg, missed sleep, participation in activities, school absences) in a group of urban, school-aged children with asthma from ethnic minority backgrounds. Specifically, the current longitudinal study examines relations between a contextual risk factor (ie, family life stressors), an asthma-related risk factor (ie, asthma symptoms), individual resources (ie, attention, children's problem-solving beliefs, and self-esteem), and aspects of asthma morbidity that have been shown to have an impact on children's academic performance. Participants of the study included 31 mother-child dyads from low-income, inner-city neighborhoods.

This two-year longitudinal study examined concurrent and across-time associations between characteristics related to context, health, and development (i.e., neighborhood disadvantage, knowledge related to asthma management and asthma management behaviors, and self-competence) and children's asthma-related functioning.

Problem: Asthma may serve as a risk factor for higher levels of psychosocial problems in urban school-aged children.

Method: Interview data were collected from 48 children (27 with asthma and 21 without asthma) and their mothers.

Findings: Asthma did not function as a risk factor for psychosocial problems in this sample.
