The current study compared parents’ emotion regulation (ER) in clinical (those with a child with externalizing behavioral problems) and low-risk comparison families. Additionally, mediation models were explored with parent ER predicting child behavior problems through child ER. Participants were 60 families with children (71.7% boys; 73% Caucasian) ages 2 through 8 years (M?=?4.62; SD?=?1.69) from a rural population in the United States: 34 clinical families referred for parent training and 26 nonclinical families. A blocking design was used to balance the two groups on key demographic characteristics. Parents’ and children’s ER was assessed using parent-report surveys and structured behavioral observations. Analyses indicated higher rates of parental emotion dysregulation (specifically, more difficulty when upset with achieving goal-directed behaviors, p?=?.01, d?=?0.67; controlling impulses, p?=?.01, d?=?0.64; limited use of ER strategies, p?=?.02, d?=?0.62; and more negative verbalizations to their child during the observed task, p?<?.01, d?=?0.73) and child emotion dysregulation (specifically, more difficulty as reported by parents, p?<?.01, d?=??2.42) in the clinical group. Mediational analyses indicated there were indirect paths from parental ER to children’s behavioral problems through child ER. Findings from this research suggest a need to measure and target ER in both parents and their children when working with families who are referred for treatment of child behavior problems.  相似文献

In concrete applications of probability, statistical investigation gives us knowledge of some probabilities, but we generally want to know many others that are not directly revealed by our data. For instance, we may know prob(P/Q) (the probability of P given Q) and prob(P/R), but what we really want is prob(P/Q&;R), and we may not have the data required to assess that directly. The probability calculus is of no help here. Given prob(P/Q) and prob(P/R), it is consistent with the probability calculus for prob(P/Q&;R) to have any value between 0 and 1. Is there any way to make a reasonable estimate of the value of prob(P/Q&;R)? A related problem occurs when probability practitioners adopt undefended assumptions of statistical independence simply on the basis of not seeing any connection between two propositions. This is common practice, but its justification has eluded probability theorists, and researchers are typically apologetic about making such assumptions. Is there any way to defend the practice? This paper shows that on a certain conception of probability—nomic probability—there are principles of “probable probabilities” that license inferences of the above sort. These are principles telling us that although certain inferences from probabilities to probabilities are not deductively valid, nevertheless the second-order probability of their yielding correct results is 1. This makes it defeasibly reasonable to make the inferences. Thus I argue that it is defeasibly reasonable to assume statistical independence when we have no information to the contrary. And I show that there is a function Y(r, s, a) such that if prob(P/Q) = r, prob(P/R) = s, and prob(P/U) = a (where U is our background knowledge) then it is defeasibly reasonable to expect that prob(P/Q&;R) = Y(r, s, a). Numerous other defeasible inferences are licensed by similar principles of probable probabilities. This has the potential to greatly enhance the usefulness of probabilities in practical application.  相似文献

Mealtimes are a common source of stress for families. Examining factors related to problem eating may provide markers by which to identify families requiring assistance and salient targets for treatment. The current study investigated parenting practices and cognitions, generalisation of child behavioural issues, and early feeding history as they relate to problem eating in typically developing young children. We compared a community sample of 105 parents of 1.5–6-year-old children via survey and observation with 96 parents seeking treatment for their child’s problem eating. History of problems with breastfeeding, χ2(1)?=?3.88, p?=?.049, and the transition to solids, χ2(1)?=?7.27, p?=?.007, were more common among problem eaters than comparisons. Problem eaters had a greater number of problem behaviours outside of mealtimes, F(1181)?=?10.88, p?=?.001, though not more frequently than comparisons and not to clinical levels, F(1181)?=?1.81, p?=?.181. Parents of problem eaters reported more unhelpful mealtime parenting strategies, F(1155)?=?22.59, p?<?.001, yet general parenting style was similar by group, F(1187)?=?0.42, p?=?.527. Parents’ cognitions about mealtimes, F(1155)?=?119.81, p?<?.001, including mealtime-specific self-efficacy, F(1155)?=?171.30, p?<?.001, were poorer amongst problem eaters, and were the only factors to predict problem eating in the total sample. General parenting self-efficacy was poorer in parents of problem eaters (Behaviour: F(1187)?=?42.36, p?<?.001; Setting: F(1187)?=?10.64, p?=?.001). Evidence of feeding issues in infancy may support early detection of and intervention for later problem eating. The significance of broader child behaviour is less clear. Parent factors, particularly those specific to mealtimes, and cognitive in nature (including mealtime parenting self-efficacy) clearly differentiated the groups, and represent important targets for intervention.  相似文献

Emotion regulation is a complex process that begins in infancy and continues through childhood with parents’ support. Early parent-child interactions shape the way children learn emotion management. We took a sociocultural and social learning approach to exploring the specific components of mother-child interactions that are related to mothers’ perceptions of her child’s regulatory ability and the child’s observed emotion regulation. Thirty mothers and their preschool children were recruited from two New England urban areas: one community sample and one head start sample. Dyads engaged in a free play session, children completed an observed compliance task, and mothers completed a set of questionnaires assessing their perceptions of their child’s regulation. Regression analyses revealed that maternal behaviors during free play predicted child’s observed hostility (F (2,29)?=?3.137, p?<?.05) and mothers’ perceptions of her child’s regulatory ability predicted observed child compliance (F (2, 17)?=?4.990, p?<?.05). Child behaviors during play significantly predicted child’s compliance (F (3,20)?=?4.722, p?<?.05) and child’s hostility (F (1, 26)?=?9.220, p?<?.001). Maternal modeling and intentional scaffolding as well as perceptions of her child’s regulatory capacity have a powerful impact on her child’s observed regulation. Results indicate that it is particularly important for mothers of preschoolers to support autonomy while guiding socially appropriate behavior. Interventions that target improving mothers’ negative perceptions of their children, educating on appropriate preschool expectations, and facilitating preschoolers’ mature play may help mothers interact with their children in the ways that foster children’s autonomous emotion regulation.  相似文献

This project examined the performance of classical and Bayesian estimators of four effect size measures for the indirect effect in a single-mediator model and a two-mediator model. Compared to the proportion and ratio mediation effect sizes, standardized mediation effect-size measures were relatively unbiased and efficient in the single-mediator model and the two-mediator model. Percentile and bias-corrected bootstrap interval estimates of ab/s Y , and ab(s X )/s Y in the single-mediator model outperformed interval estimates of the proportion and ratio effect sizes in terms of power, Type I error rate, coverage, imbalance, and interval width. For the two-mediator model, standardized effect-size measures were superior to the proportion and ratio effect-size measures. Furthermore, it was found that Bayesian point and interval summaries of posterior distributions of standardized effect-size measures reduced excessive relative bias for certain parameter combinations. The standardized effect-size measures are the best effect-size measures for quantifying mediated effects.  相似文献

There seem to be two ways of supposing a proposition: supposing “indicatively” that Shakespeare didn’t write Hamlet, it is likely that someone else did; supposing “subjunctively” that Shakespeare hadn’t written Hamlet, it is likely that nobody would have written the play. Let P(B//A) be the probability of B on the subjunctive supposition that A. Is P(B//A) equal to the probability of the corresponding counterfactual, A B? I review recent triviality arguments against this hypothesis and argue that they do not succeed. On the other hand, I argue that even if we can equate P(B//A) with P(A B), we still need an account of how subjunctive conditional probabilities are related to unconditional probabilities. The triviality arguments reveal that the connection is not as straightforward as one might have hoped.  相似文献

Hypocrisy is widely thought to be morally objectionable in a way that undermines the hypocrite’s moral standing to blame others. To wit, we seem to intuitively accept the “Nonhypocrisy Condition:” R has the standing to blame S for some violation of a moral norm N only if R’s blaming S is not hypocritical. This claim has been the subject of intensifying philosophical investigation in recent years. However, we can only understand why hypocrisy is morally objectionable and has an effect on standing to blame if we can correctly characterize hypocrisy itself. Unfortunately, some recent discussions fail to do this, which fatally undermines subsequent arguments concerning the effect of hypocrisy on the standing to blame. This paper’s central aim is to develop and defend a better account of hypocrisy. The hope is that with such an account in hand, we can explain and perhaps justify our moral aversion to hypocrisy in general as well as the Nonhypocrisy Condition in particular.  相似文献

Despite many observations of cooperation in nature, laboratory studies often fail to find careful coordination between individuals who are solving a cooperative task. Further, individuals tested are often naïve to cooperative tasks and there has been little exploration of partnerships with mixed expertise. In the current study, we examined acquisition of a cooperative pulling task in a group with both expert (N = 4) and novice (N = 11) chimpanzees (Pan troglodytes). We used five measures of competence and understanding: (1) success at the task, (2) latency to succeed, (3) efficiency, (4) uncoordinated pulling, and (5) pulling when a partner was present versus absent. We found that novices showed evidence of trial and error learning and developed competence over time, whereas the behavior of experts did not change throughout the course of the study. In addition to looking at patterns over time, we compared the performance of novices in this mixed-expertise group to an earlier study of novices in a group of all-novices. Novices in the mixed-expertise group pulled the same overall amount but for shorter periods of time, leading to higher pulling rates than individuals in the all-novice group. Taken together, these results suggest that learning in the presence of experts led to rapid and frequent success, although not necessarily careful coordination.  相似文献

Building upon the redefinition of exploration as a family process, this study analyses how the processes of family stability and change may favour exploration by members of multiple family relational contexts. Sixty non-clinical family triads (mother, father, child) participated in an experimental observational study and were video-recorded while playing in different interactive configurations. The children (37 females and 23 males) were 4–5 years old (M?=?55 months). The mothers’ ages ranged from 29 to 45 (M?=?38) and the fathers’ ages ranged from 29 to 46 (M?=?39). All the parents were employed and were living together. All participants were Caucasians of Italian nationality. Using the Triadic Interactions Analytical Procedure (TIAP), the family morphostatic processes and the family morphogenetic processes were analysed in relation to the family members’ exploration. Data analyses showed that family stability continual construction (morphostasis) and family change (morphogenesis) involve different interactive and relational dynamics (χ²(8)?=?13.84, p?>?.05; CFI?=?.97, TLI?=?.94, SRMR?=?.06), even if they are intertwined processes (p?<?.001). Both morphostatic and morphogenetic processes were correlated to the level of exploration showed by family members (respectively r?=?.32, p?<?.05, and r?=?.59, p?<?.001), even if the morphogenetic processes had a stronger relation with family exploration (z?=?1.85, p one-tailed ?<?.05).  相似文献

Performance measures such as log d and d′?aim to measure stimulus discriminability independently of response bias in conditional discrimination tasks, including the yes/no signal-detection procedure. However, they assume only one dimension of bias (e.g., response color) and do not account for bias on additional dimensions (e.g., response side). Such bias reduces log d, thus violating the statistical independence of discriminability and bias measurements. We modified log d to account for side bias and reanalyzed previous side-biased data. With strong side bias, the modified log d differed enough from the standard log d to potentially alter the conclusions of an experiment. Simulations showed that the modified log d produces discriminability estimates that are more accurate and bias-independent than the standard log d calculation.  相似文献

Orthomodular lattices with a two-valued Jauch–Piron state split into a generalized orthomodular lattice (GOML) and its dual. GOMLs are characterized as a class of L-algebras, a quantum structure which arises in the theory of Garside groups, algebraic logic, and in connections with solutions of the quantum Yang–Baxter equation. It is proved that every GOML X embeds into a group G(X) with a lattice structure such that the right multiplications in G(X) are lattice automorphisms. Up to isomorphism, X is uniquely determined by G(X), and the embedding \(X\hookrightarrow G(X)\) is a universal group-valued measure on X.  相似文献

According to the Ramsey Test, conditionals reflect changes of beliefs: α?>?β is accepted in a belief state iff β is accepted in the minimal revision of it that is necessary to accommodate α. Since Gärdenfors’s seminal paper of 1986, a series of impossibility theorems (“triviality theorems”) has seemed to show that the Ramsey test is not a viable analysis of conditionals if it is combined with AGM-type belief revision models. I argue that it is possible to endorse that Ramsey test for conditionals while staying true to the spirit of AGM. A main focus lies on AGM’s condition of Preservation according to which the original belief set should be fully retained after a revision by information that is consistent with it. I use concrete representations of belief states and (iterated) revisions of belief states as semantic models for (nested) conditionals. Among the four most natural qualitative models for iterated belief change, two are identified that indeed allow us to combine the Ramsey test with Preservation in the language containing only flat conditionals of the form α?>?β. It is shown, however, that Preservation for this simple language enforces a violation of Preservation for nested conditionals of the form α?>?(β?>?γ). In such languages, no two belief sets are ordered by strict subset inclusion. I argue that it has been wrong right from the start to expect that Preservation holds in languages containing nested conditionals.  相似文献

The purpose of the multi-measure, multi-wave, longitudinal study was to examine the interactive relation between behavioral distress tolerance (DT) and perceived social support (PSS) in 352 tornado-exposed adolescents aged 12–17 years (M = 14.44; SD = 1.74). At baseline, adolescents completed a computer-based task for DT, and self-report measures of PSS, depressed mood, posttraumatic stress disorder (PTSD), substance use, and interpersonal conflict. Symptoms also were assessed 4 and 12 months after baseline. Findings showed that lower levels of DT together with lower levels of PSS conferred risk for elevated symptoms of prospective depression (t(262) = ?2.04, p = .04; reffect size = 0.13) and PTSD (t(195) = ?2.08, p = .04; reffect size = 0.15) following a tornado. However, only PSS was significant in substance use t(139) = 2.20, p = .03; reffect size=0.18) and conflict (t(138) = ?4.05, p < .0001; reffect size=0.33) in our sample. Implications regarding adolescent DT, the transdiagnostic nature of PSS, and the clinical applications of our findings in the aftermath of a natural disaster are discussed.  相似文献

We compared factors influencing adolescents’ self-control according to their family structure. Participants were 944 adolescents in five cities in South Korea (115 from single-parent families, 65 from grandparent-led families, and 764 from two-parent families). Data were collected using self-report questionnaires containing items on self-control, stress, parenting attitude, parent–adolescent communication, and family cohesion. Data were analyzed using stepwise multiple regressions with SPSS program. The factors influencing adolescents’ self-control differed across the three family structure groups. For single-parent families, stress and parental attitudes were significantly related to adolescents’ self-control (adjusted R2?=?0.37, p?<?0.001). In contrast, for grandparent-led families, family cohesion and parental attitude were significantly related to adolescents’ self-control (adjusted R2?=?0.31, p?<?0.01), while for two-parent families, stress, parental attitude, and parent–adolescent communication were related to the outcome (adjusted R2?=?0.24, p?<?0.001). Parental attitude was thus a common factor relating to self-control, regardless of family structure. On the other hand, the main factors influencing adolescents with low self-control were gender and stress. Our results confirm that adolescents’ self-control is not only affected by personal factors but also by parental and family factors. It is important to improve individual program to improve adolescents’ self-control according to family structure. The results of study may act as a base for improving individual intervention programs aimed at promoting adolescents’ self-control by factoring in family structure.  相似文献

This study aims to investigate the associations between quality of life, physical activity and mood states in women with breast cancer. A total of 354 women (mean age, 51.74?±?8.63 years; body mass index (BMI), 28?±?5.67 kg/m2) completed the Baecke Physical Activity Questionnaire, Profile of Mood States (POMS), European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Pearson’s correlation and multiple linear regressions were used to verify the relations between outcomes and independent variables. Correlations between scores on POMS, Baecke Physical Activity Questionnaire and global health status/quality of life subscale of EORTC QLQ-C30 found associations (p?<?0.01) between physical activity (r?=?0.191), vigour (r?=?0.333) and fatigue (r?=??0.433). Multiple linear regression analysis of the global health status/quality of life subscale of the EORTC QLQ-C30 showed significant differences for vigour (p?<?0.001), social function (p?=?0.003), side effects of systemic therapy (p?=?0.019), arm and breast symptoms (p?<?0.001) and Baecke physical activity score (p?=?0.006). Physical activity is an independent factor related to the quality of life in women with breast cancer. Understanding these variables may influence clinical decisions during treatment and allow positive interventions regarding symptoms, functions and lifestyle.  相似文献

Perfectionism is hypothesized to contribute to the etiology of anorexia nervosa (AN). However, there is little research regarding whether individuals with AN can be classified according to maladaptive (e.g., evaluative concerns) and adaptive (e.g., high personal standards) facets of perfectionism that predict distinct outcomes and might warrant different intervention approaches. In this study, a latent profile analysis was conducted using data from adults with AN (n?=?118). Frost Multidimensional Perfectionism Scale (Frost et al. Cognitive Therapy and Research, 14(5), 449–46, 1990) subscales were used to identify subgroups differing according to endorsed perfectionism features (e.g., adaptive and maladaptive perfectionism). Generalized linear models were used to compare subgroups on eating disorder and affective symptoms measured through questionnaire and ecological momentary assessment. Four subgroups were identified: (a) Low Perfectionism; (b) High Adaptive and Maladaptive Perfectionism; (c) Moderate Maladaptive Perfectionism; and (d) High Maladaptive Perfectionism. Subgroups differed on overall eating disorder symptoms (p?<?.001), purging (p?=?.005), restrictive eating (p?<?.001), and body checking (p?<?.001) frequency, depressive (p?<?.001) and anxiety (p?<?.001) symptoms, and negative (p?=?.001) and positive (p?<?.001) affect. The Low Perfectionism group displayed the most adaptive scores and the Moderate and High Maladaptive Perfectionism groups demonstrated the most elevated clinical symptoms. The High Adaptive and Maladaptive Perfectionism group demonstrated low affective disturbances, but elevated eating disorder symptoms. Results support the clinical significance of subtyping according to perfectionism dimensions in AN. Research is needed to determine if perfectionism subtyping can enhance individualized treatment targeting in AN.  相似文献

There is a lack of psychometrically sound tools for measuring youth outcomes in out-of-school time (OST) settings. Consequently, behavior ratings completed by OST staff are being scored as though the raters were teachers, even though cross-informant correlations are notoriously low (meta-analysis r?=?.27). Across 26 schools, 227 students were assessed by both teachers and OST staff using the Devereux Student Strengths Assessment (DESSA) to measure Social Emotional Competence. These 4th and 5th grade students were 50% male; 53% 5th graders; and 51% Latino, 20% Mixed/Other, 11% Black, 11% Asian, and 7% White. In the full sample, OST staff rated children’s behavior more harshly than teachers (p?<?.001; d?=?.32), although the scores were associated (r?=?.31, p?<?.001). Among the ratings completed within the same week, teacher and staff distributions were not statistically different. Teacher and staff ratings had a “medium” correlation (r?=?.42; p?=?.01) and a classification consistency (88%) that exceeded chance by a “moderate” amount (κ?=?.43). Few, if any, studies have previously compared the ratings of the same children by teachers and OST providers. Cross-informant inter-rater reliability between teachers and OST staff was higher than expected on the DESSA.  相似文献

The duality between congruence lattices of semilattices, and algebraic subsets of an algebraic lattice, is extended to include semilattices with operators. For a set G of operators on a semilattice S, we have \({{\rm Con}(S,+,0,G) \cong^{d} {{\rm S}_{p}}(L,H)}\), where L is the ideal lattice of S, and H is a corresponding set of adjoint maps on L. This duality is used to find some representations of lattices as congruence lattices of semilattices with operators. It is also shown that these congruence lattices satisfy the Jónsson–Kiefer property.  相似文献
