Frequent emesis can cause substantial deleterious effects to a child's health and environment. We conducted a functional analysis of a 3‐year‐old girl's self‐induced emesis and confirmed that emesis was maintained by automatic reinforcement. In a reversal design, we evaluated the efficacy of implementing response blocking at 100% and 50% treatment integrity levels on both attempts and successful production of emesis. One hundred percent blocking, but not 50% blocking, was successful in reducing attempts and emesis below baseline levels.  相似文献

Prior research on the effects of personality on the variability of states has either not assessed states in real-life contexts or not incorporated meaningful contextual information when analyzing state variability. Providing an integrated contextualized approach, we introduce the Within and Across Context (WAC) Variability framework that disentangles real-life within-person fluctuations occurring within and across real-life contexts. To illustrate the utility of this framework, we investigated effects of Big Five personality traits on the level and the within- and cross-context variability of experience-sampled states (affect, self-esteem, behavior) of psychology freshmen (N = 118). Results provide initial empirical support for the meaningful separation of within- and cross-context variability and their distinct relations to personality.  相似文献

Recent research has underscored the importance of elucidating specific patterns of emotion that characterise mental disorders. We examined two emotion traits, emotional variability and emotional clarity, in relation to both categorical (diagnostic interview) and dimensional (self-report) measures of major depressive disorder (MDD) and social anxiety disorder (SAD) in women diagnosed with MDD only (n?=?35), SAD only (n?=?31), MDD and SAD (n?=?26) or no psychiatric disorder (n?=?38). Results of the categorical analyses suggest that elevated emotional variability and diminished emotional clarity are transdiagnostic of MDD and SAD. More specifically, emotional variability was elevated for MDD and SAD diagnoses compared to no diagnosis, showing an additive effect for co-occurring MDD and SAD. Similarly diminished levels of emotional clarity characterised all three clinical groups compared to the healthy control group. Dimensional findings suggest that although emotional variability is associated more consistently with depression than with social anxiety, emotional clarity is associated more consistently with social anxiety than with depression. Results are interpreted using a threshold and dose–response framework.  相似文献

Working memory (WM) and behavioral inhibition impairments have garnered significant attention as candidate core features, endophenotypes, and/or associated neurocognitive deficits of attention-deficit/hyperactivity disorder (ADHD). The relationship between ADHD-related WM and inhibition deficits remains relatively unclear, however, with inferences about the constructs’ directional relationship stemming predominantly from correlational research. The current study utilized a dual-task paradigm to experimentally examine the relationship between ADHD-related WM and behavioral inhibition deficits. A total of 31 boys (15 ADHD and 16 typically developing [TD]) aged 8–12 years completed WM (1-back and 2-back), behavioral inhibition (stop-signal task [SST]), and dual-condition (1-back/SST and 2-back/SST) experimental tasks. Children with ADHD exhibited significant, large-magnitude WM deficits for the 1-back condition but were not significantly different from children in the TD group for the 2-back, 1-back/SST, and 2-back/SST conditions. Children with ADHD also exhibited significant inhibition deficits for the SST, 1-back/SST, and 2-back/SST conditions, but the within-group effect was not significant. The findings suggest that ADHD-related stop-signal demands are upstream, or compete for, resources involved in controlled-focused attention and/or other central executive (CE), WM processes.  相似文献

The development of self‐regulation is influenced by various child‐level and family‐level characteristics. Previous research focusing on the preschool period has reported a female advantage in self‐regulation and negative effects of various adverse features of the family environment on self‐regulation. The present study aimed to investigate growth in self‐regulation (i.e., executive functioning and behavioral self‐regulation) over 1 school year during early elementary school and to explore the influences of child sex, the level of home chaos, and family educational resources on self‐regulation. Participants were 263 German children (51% boys; mean age 8.59 years, SD = 0.56 years). Data were collected during the fall and spring of the school year. A computer‐based standardized test battery was used to assess executive functioning. Caregiver ratings assessed children's behavioral self‐regulation and information on the family's home environment (chaotic home environment and educational resources). Results suggest growth in elementary school children's executive functioning over the course of the school year. However, there were no significant changes in children's behavioral self‐regulation between the beginning and the end of Grade 3. Sex differences in executive functioning and behavioral self‐regulation were found, suggesting an advantage for boys. Educational resources in the family but not chaotic family environment were significantly related to self‐regulation at both time‐points. Children from families with more educational resources scored higher on self‐regulation measures compared to their counterparts from less advantaged families. We did not find evidence for child‐level or family‐level characteristics predicting self‐regulation growth over time. Findings suggest that the male disadvantage in self‐regulation documented in previous studies might be specific to characteristics of the sample and the context in which the data were collected. Adequate self‐regulation skills should be fostered in both girls and boys. Results also add to the importance of supporting self‐regulation development in children from disadvantaged family backgrounds early in life.  相似文献

Future counselors are likely to work with clients with process/behavioral addictions (PBA). The behavioral addiction knowledge survey (BAKS) was designed to determine counseling students’ knowledge of PBAs. This article presents the instrument development procedures and results of a preliminary exploratory factor analysis (EFA) and a Rasch analysis of the BAKS. The sample size included 77 counseling students. The EFA suggested a three-factor, 18-item solution, with satisfactory internal consistency within each factor. Rasch analysis results also yielded excellent infit and outfit statistics. Detailed psychometric properties of the BAKS are provided. Implications for counselor educators, supervisors, and future researchers are included.  相似文献

Sex addiction prevalence is estimated between 3% and 10%. There are multiple pathways to its development including biological predispositions, trauma and attachment issues, comorbid conditions, among others. Although controversy still surrounds sex addiction's conceptualization, diagnosis, and treatment, some approaches to treatment have shown promise, including cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and use of selective serotonin reuptake inhibitors (SSRIs). Empirical support, clinical implications, and future directions are discussed.  相似文献

Preexposure prophylaxis (PrEP) prevents human immunodeficiency virus (HIV) but not other sexually transmitted infections (STIs). Men who have sex with men (MSM) who take PrEP tend to report reduced condom use, but little is known about the underlying mechanisms. For this study, MSM who take PrEP (i.e., PrEP experienced; n = 88) and MSM who do not (i.e., PrEP naïve; n = 113) completed an online study, including the condom purchase task (CoPT). The CoPT assesses decisions to purchase condoms across escalating prices (range: free–$55) for sex with different types of hypothetical partners: those least likely to have an STD (least STD) and those that participants most want to have sex with (most want sex with). When condoms were free, PrEP-experienced MSM had a lower rate of condom purchasing than did PrEP-naïve MSM. For both partner types, PrEP-experienced MSM reached a price break point (i.e., would not buy condoms) at a lower price than did PrEP-naïve pariticipants. For the most-want-sex-with partner at the price at which participants elected not to buy condoms, only 23% of PrEP-experienced MSM chose to abstain from sex when not purchasing condoms versus 53% among PrEP-naïve MSM. Similar patterns were observed for the least-STD partner. The results support the potential utility of the CoPT in identifying behavioral mechanisms related to condom use and PrEP.  相似文献

Coinciding with widespread efforts to address obesity, weight bias internalization (a process of self-devaluation wherein individuals apply weight-biased stereotypes to themselves) has gained increased attention as a robust correlate of poor health outcomes. The present meta-analysis aimed to provide the largest quantitative synthesis of associations between weight bias internalization and health-related correlates. Studies that provided zero-order correlations for cross-sectional or prospective associations between weight bias internalization and physical, psychosocial, and behavioral health correlates were included in the meta-analysis. Meta-regression determined whether these associations differed based on demographic (sex/gender, race, age), anthropometric (body mass index), and study-level (publication status, sample type, study quality) moderators. Data for 149 (sub)samples were identified that included between 14 and 18,766 participants (M sample size = 534.96, SD = 1,914.43; M age = 34.73, SD = 12.61, range = 9.95–65.70). Results indicated that greater weight bias internalization was concurrently associated with worse psychosocial (e.g., negative and positive mental health, social functioning), physical (e.g., BMI, weight maintenance, health-related quality of life [HRQoL]), and behavioral health (e.g., disordered eating behaviors, healthy eating, physical activity) across most constructs, with effects ranging from small to very large in magnitude. Preliminary evidence also suggested that greater weight bias internalization was subsequently associated with less weight loss and increased negative mental health. Notable variations in the nature and magnitude of these associations were identified based on the health-related correlate and moderator under consideration. These findings indicate that weight bias internalization is linked to multiple adverse health-related outcomes and provide insight into priorities for future research, theory building, and interventions in this area.  相似文献

The National Institutes of Health established the Science of Behavior Change (SOBC) program to promote basic research on the initiation, personalization, and maintenance of health behavior change. The SOBC Resource and Coordinating Center now leads and supports activities to maximize the creativity, productivity, scientific rigor, and dissemination of the experimental medicine approach and experimental design resources. Here, we highlight those resources, including the Checklist for Investigating Mechanisms in Behavior-change Research (CLIMBR) guidelines introduced in this special section. We describe the ways in which SOBC can be applied across a range of domains and contexts, and end by considering ways to extend SOBC’s perspective and reach, so as to best promote behavior change linked with health, quality of life, and well-being.  相似文献
