Specifying the determinants of the initiation and maintenance of behavior change: an examination of self-efficacy, satisfaction, and smoking cessation.

Using data from smokers (N = 591) who enrolled in an 8-week smoking cessation program and were then followed for 15 months, the authors tested the thesis that self-efficacy guides the decision to initiate smoking cessation but that satisfaction with the outcomes afforded by quitting guides the decision to maintain cessation. Measures of self-efficacy and satisfaction assessed at the end of the program, 2 months, and 9 months were used to predict quit status at 2, 9, and 15 months, respectively. At each point, participants were categorized as either initiators or maintainers on the basis of their pattern of cessation behavior. Across time, self-efficacy predicted future quit status for initiators, whereas satisfaction generally predicted future quit status for maintainers. Implications for models of behavior change and behavioral interventions are discussed.     

Some task demands induce collapsing bounds: Evidence from a behavioral analysis

Traditional models of choice-response time assume that sensory evidence accumulates for choice alternatives until a threshold amount of evidence has been obtained. Although some researchers have characterized the threshold as varying randomly from trial to trial, these investigations have all assumed that the threshold remains fixed across time within a trial. Despite decades of successful applications of these models to a variety of experimental manipulations, the time-invariance assumption has recently been called into question, and a time-variant alternative implementing collapsing decision thresholds has been proposed instead. Here, we investigated the fidelity of the collapsing threshold assumption by assessing relative model fit to data from a highly constrained experimental design that coupled a within-subject mixture of two classic response time paradigms—interrogation and free response—within a random dot motion (RDM) task. Overall, we identified strong evidence in favor of collapsing decision thresholds, suggesting that subjects may adopt a dynamic decision policy due to task characteristics, specifically to account for the mixture of response time paradigms and motion strengths across trials in the mixed response signal task. We conclude that time-variant mechanisms may serve as a viable explanation for the strategy used by human subjects in our task.     

Development,Feasibility, and Refinement of a Toxic Stress Prevention Research Program

Innovative interventions accessible to at-risk populations to prevent the intergenerational cycle of toxic stress are needed. This paper describes the iterative development of a community-based intervention, 2Gen Thrive, which was designed to prevent toxic stress and promote resilience by improving caregiver capacity to respond to children’s emotional, behavioral, and developmental needs. 2Gen Thrive leverages the collaboration between a Children’s Hospital and an Early Head Start/Head Start education center to help low-income, minority families thrive in the context of risk factors for toxic stress. In this paper, we focus on the process of developing, piloting, and refining our 2Gen Thrive preventive intervention research program, which has been developed following a community-based participatory research (CBPR) approach. The primary objective was to pilot test two prevention interventions we adapted for use in this target population: Classroom Theraplay, a classroom-wide intervention designed to prevent toxic stress among children exposed to adversity by fostering nurturing relationships with their teachers; and Dialectical Behavior Therapy Skills Training for Parents (DBT4P), a group intervention developed to bolster parental responsiveness by teaching Dialectical Behavioral Therapy (DBT) mindfulness and emotion regulation skills. We evaluated qualitative and process data as well as quantitative data from standardized instruments, including The Classroom Assessment Scoring System (CLASS), Patient Health Questionnaire (PHQ-9), Difficulties in Emotion Regulation Scale (DERS), and Parenting Stress Index (PSI/SF). Results demonstrate the feasibility, acceptability, and appropriateness of these preventive interventions delivered in the early education setting, and of conducting intervention research using a CBPR approach.     

Age-related changes in neural mechanisms of prospective memory

The capability to remember and execute intentions in the future – termed prospective memory (PM) – may be of special significance for older adults to enable successful completion of important activities of daily living. Despite the importance of this cognitive function, mixed findings have been obtained regarding age-related decline in PM, and, currently, there is limited understanding of potential contributing mechanisms. In the current study, older (N=41) and younger adults (N=47) underwent task-functional MRI during performance of PM conditions that encouraged either spontaneous retrieval (Focal) or sustained attentional monitoring (Non-focal) to detect PM targets. Older adults exhibited a reduction in PM-related sustained activity within the anterior prefrontal cortex (aPFC) and associated dorsal frontoparietal cognitive control network, due to an increase in non-specific sustained activation in (no-PM) control blocks (i.e., an age-related compensatory shift). Transient PM-trial specific activity was observed in both age groups within a ventral parietal memory network that included the precuneus. However, within a left posterior inferior parietal node of this network, transient PM-related activity was selectively reduced in older adults during the non-focal condition. These age differences in sustained and transient brain activity statistically mediated age-related declines in PM performance, and were potentially linked via age-related changes in functional connectivity between the aPFC and precuneus. Together, they support an account consistent with the Dual Mechanisms of Control framework, in which age-related PM declines are due to neural mechanisms that support proactive cognitive control processes, such as sustained attentional monitoring, while leaving reactive control mechanisms relatively spared.
