Objective: To examine longitudinally the adaptive behavior patterns in fragile X syndrome.

Method: Caregivers of 275 children and adolescents with fragile X syndrome and 225 typically developing children and adolescents (2-18 years) were interviewed with the Vineland Adaptive Behavior Scales every 2 to 4 years as part of a prospective longitudinal study.

Results: Standard scores of adaptive behavior in people with fragile X syndrome are marked by a significant decline over time in all domains for males and in communication for females. Socialization skills are a relative strength as compared with the other domains for males with fragile X syndrome. Females with fragile X syndrome did not show a discernible pattern of developmental strengths and weaknesses.

Conclusions: This is the first large-scale longitudinal study to show that the acquisition of adaptive behavior slows as individuals with fragile X syndrome age. It is imperative to ensure that assessments of adaptive behavior skills are part of intervention programs focusing on childhood and adolescence in this condition.

To determine if the use of theory, data and end-user perspectives to guide an adaptation of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) yields better outcomes and improves the "fit" of TranS-C to community mental health centers (CMHCs), relative to the standard version. Ten counties in California were cluster-randomized by county to Adapted or Standard TranS-C. Within each county, adults who exhibited sleep and circadian dysfunction and serious mental illness (SMI) were randomized to immediate TranS-C or Usual Care followed by Delayed Treatment with TranS-C (UC-DT).

Adaptive behavior depends on the ability to predict specific events, particularly those related to rewards. Armed with such associative information, we can infer the current value of predicted rewards based on changing circumstances and desires. To support this ability, neural systems must represent both the value and identity of predicted rewards, and these representations must be updated when they change.

The ability to observe the social behavior of others and use observed information to bias future action is a fundamental building block of social cognition . A foundational question is whether social observation and experience engage common circuit mechanisms that enable behavioral change. While classic studies on social learning have shown that aggressive behaviors can be learned through observation , it remains unclear whether aggression observation promotes persistent neural changes that generalize to new contexts.

Background: Self-directed interventions are cost-effective for patients with cancer and their family caregivers, but barriers to use can compromise adherence and efficacy.

Aim: Pilot a Sequential Multiple Assignment Randomized Trial (SMART) to develop a time-varying dyadic self-management intervention that follows a stepped-care approach in providing different types of guidance to optimize the delivery of Coping-Together, a dyadic self-directed self-management intervention.

Methods: 48 patients with cancer and their caregivers were randomized in Stage 1 to: (a) Coping-Together (included a workbook and 6 booklets) or (b) Coping-Together + lay telephone guidance.

Objective: Studies have found that cancer patients with dependent children exhibit high symptoms of anxiety, depression, and worry. Patients' parenting concerns can negatively impact their own and their family's adjustment to the cancer experience. However, relatively little is known about parenting concerns of partners of cancer patients, or associations between parenting concerns and couples' relationship adjustment.
