Escalating schedules of incentives increase physical activity with no differences between deposit and no-deposit groups: A systematic replication

Physical inactivity has increasingly affected public health in the United States during the COVID-19 pandemic as it is associated with chronic diseases such as arthritis, cancer, and heart disease. Contingency management has been shown to increase physical activity. Therefore, the present study sought to evaluate the effects of an escalating schedule of monetary reinforcement with a reset contingency on physical activity, as compared between 2 counterbalanced groups in which a monetary deposit of $25 was either required (deposit group) or not (no-deposit group). Twenty-five adults wore Fitbit accelerometers to monitor step counts. An ABA reversal design was used; in the 2 baseline phases, no programmed contingencies were in place for step counts. During intervention, step goals were set using a modified 70^th percentile schedule with a 7-day window: Reaching the first goal would result in $0.25, and incentives increased by $0.25 for each subsequent day in which the goal was met. Failure to reach a goal resulted in a reset of the monetary incentive value to $0.25. Ten out of 12 participants from the deposit group were determined to be responders to intervention, whereas 8 out of 13 participants from the no-deposit group were determined to be responders to intervention. Overall, there were no significant differences between the groups' step counts. However, the deposit group's intervention was cheaper to implement, which suggests that deposit contracts are a viable modification for physical activity interventions.     

The Effects of a Learning Station on the Completion and Accuracy of Math Homework for Middle School Students

We studied the effects of a Learning Station on the completion and accuracy of math homework of middle school students who had chronic homework problems. The Learning Station was a three sided free-standing panel with theoretically and empirically-based components involving (a) stimulation (color, music, activity breaks, and choice) and (b) self-attention (mirror and self-monitoring). Two students who used the Station tripled their accuracy and the amount of homework completed as assessed in a multiple baseline across participants design. One student with high academic abilities elected not to use the intervention, because he worked quickly (albeit carelessly) at school to complete his homework during baseline and during intervention. The practical and research implications of the findings are discussed.     

Increasing parenting self-efficacy: The Fussy Baby Network® intervention

High levels of infant crying place families at risk for disrupted relationships, parenting stress, and even for child maltreatment. We conducted an evaluation of the Fussy Baby Network^® (FBN), a program supporting families struggling with infant crying and related concerns. The study contrasted 29 families who sought help from FBN with 27 families with excessively crying infants who did not seek services. Researchers measured parenting self-efficacy, depression, and stress in each group before and after the intervention. Results from hierarchical multiple regression analysis indicated greater improvements over time in parenting self-efficacy for parents receiving FBN services. Furthermore, the greater improvements in parenting self-efficacy in the intervention group were not directly attributable to reductions in infant crying. These findings provide preliminary evidence that the FBN approach may be effective at boosting the confidence of parents struggling with caring for their infants. Future research with larger samples with baseline equivalence and stronger research designs should explore this intervention further. This study also suggests that interventions for families with excessively crying infants should move beyond the focus of reducing infant crying to a broader strategy of supporting parents and strengthening relationships between parents and their infants to build parenting capacity.     

Support networks of adolescent mothers: Effects on parenting experience and behavior

The relation between social support and lower-income African-American adolescent mothers' parenting experience, parenting behavior, and psychological symptoms was studied. Larger support networks were associated with better maternal adjustment unless individuals providing support were also providers of conflict. The young women's own mothers were their most prominent providers of support, and the number of different types of support the grandmother provided was related positively to quality of the adolescent's parenting behavior, but negatively to her experience of parenting. Having more friends in the network was related to better parenting behavior, but having more siblings in the network was related to poorer parenting behavior as well as more psychological symptoms. Although most of the young women relied on male partners for support, no variables related to provision of support by male partners were correlated with maternal adjustment.     

中医药临床实践的价值

把现代病因病理医学作为参照物,通过比较,指出中医的证是病人的全身综合反应状态,是病因病理医学之外的另外一个临床医学范畴。状态与病因病理是人类疾病的两个不同方面。从单纯状态病,西医难治和不治的疾病,常见病的治疗,中医药的近期疗效和远期疗效等方面阐述了中医药的临床价值。
