Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; Mage = 11.55, SD = 1.69, 9–15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors.

Research Highlights

  • Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating).
  • Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.

A scaled difference test statistic [(T)\tilde]d\tilde{T}{}_{d} that can be computed from standard software of structural equation models (SEM) by hand calculations was proposed in Satorra and Bentler (Psychometrika 66:507–514, 2001). The statistic [(T)\tilde]d\tilde{T}_{d} is asymptotically equivalent to the scaled difference test statistic [`(T)]d\bar{T}_{d} introduced in Satorra (Innovations in Multivariate Statistical Analysis: A Festschrift for Heinz Neudecker, pp. 233–247, 2000), which requires more involved computations beyond standard output of SEM software. The test statistic [(T)\tilde]d\tilde{T}_{d} has been widely used in practice, but in some applications it is negative due to negativity of its associated scaling correction. Using the implicit function theorem, this note develops an improved scaling correction leading to a new scaled difference statistic [`(T)]d\bar{T}_{d} that avoids negative chi-square values.  相似文献

Objective

Videoconferencing psychotherapy (VCT) is an effective treatment option. Yet, it is unclear whether a similar therapeutic alliance as in conventional face-to-face psychotherapy (F2F) can be achieved, since previous studies yielded mixed results. Furthermore, surveys about the attitudes towards VCT amongst patients have been missing until now. The current study gathered opinions from patients and psychotherapists about the perceived comparability of VCT and F2F regarding contextual factors and treatment characteristics, focusing on therapeutic alliance and empathy.

Method

An online survey amongst patients (N = 189) and practitioners (N = 57) taking part in cognitive behavioural therapy was conducted after the first lockdown in Germany due to the COVID-19 pandemic and a resulting transition from F2F to VCT for most participants.

Results

While patients experienced therapeutic alliance and empathy as comparable, psychotherapists indicated advantages of F2F. Both groups indicated advantages of F2F for the therapy contents and expressed advantages of VCT for flexibility regarding location and time. More than half of the participants expressed a preference for a combination of analogue and digital therapy.

Conclusion

The perceived disadvantages of VCT can be addressed, for example, with training programmes for psychotherapists targeting communication in VCT and adapting established psychotherapy methods to a digital format to further improve VCT.  相似文献

The benefits of active music participation and training for cognitive development have been evidenced in multiple studies, with this link leveraged in music therapy approaches with clinical populations. Although music, rhythm, and movement activities are widely integrated into children's play and early education, few studies have systematically translated music therapy-based approaches to a nonclinical population to support early cognitive development. This study reports the follow-up effects of the Rhythm and Movement for Self Regulation (RAMSR) program delivered by generalist preschool teachers in low socioeconomic communities. This randomized control trial (RCT) involved 213 children across eight preschools in disadvantaged communities in Queensland, Australia. The intervention group received 16–20 sessions of RAMSR over 8 weeks, while the control group undertook usual preschool programs. Primary outcome measures included executive function (child assessment of shifting, working memory, and inhibition) and self-regulation (teacher report), with secondary outcomes of school readiness and visual-motor integration. Data were collected pre- and post-intervention, and again 6 months later once children had transitioned into school. Results demonstrated significant intervention effects across the three time points for school readiness (p = 0.038, ηp2 = 0.09), self-regulation (p < 0.001, ηp2 = 0.08), and inhibition (p = 0.002 ηp2 = 0.23). Additionally, the feasibility of building capacity in teachers without any music background to successfully deliver the program was evidenced. These findings are important given that children from low socioeconomic backgrounds are more likely to need support for cognitive development yet have inequitable access to quality music and movement programs.

Research Highlights

  • Initial effects of self-regulation from a rhythm and movement program were sustained following transition into school for children from disadvantaged backgrounds.
  • Delayed effects of inhibition and school readiness from a rhythm and movement program appeared 6 months post-intervention as children entered school.
  • Generalist teachers can successfully implement a rhythm and movement program, which boosts critical developmental cognitive skills.

Background

Establishing the value of differing treatments for depression and anxiety is crucial in a climate of delimited spending and increased demand. Drawing from a well-founded, diverse evidence base is salient to constructive evaluation and any subsequent recommendations being fit for purpose.

Design

This study employed a practice-based quantitative design to explore therapeutic gains in adult counselling clients attending person-centred therapy (n = 301), delivered in a charitable, community-based UK service.

Measures

Outcome measures PHQ-9 and GAD-7 were used from three time points: initial assessment (IA), first ongoing session and last or 6th ongoing appointment (whichever occurred first; T1, T2 and T3).

Analysis

Repeated measures ANOVA, CSI, RI and RCSI calculations were used to consider significant change in clients.

Findings

Reductions in PHQ-9 and GAD-7 outcome measures were observed over time (between T2 & T3 and T1 & T3) and were all statistically significant (p = <0.001). By T3: CSI was achieved by 48.1% of clients on PHQ-9 and 50.8% of clients on GAD-7, RI was achieved by 47.8% of clients on PHQ-9 and 60.5% of clients on GAD-7, and RCSI was achieved by 32.6% of clients on PHQ-9 and 41.2% of clients on GAD-7.

Conclusions

The treatment observed resulted in effective outcomes equivalent to other therapies reviewed in the literature for clients' symptoms of anxiety and depression as measured by GAD-7 and PHQ-9.  相似文献

Objective

Feasibility, acceptability, and efficacy of a Dialectical Behavioral Therapy (DBT) -based method developed in Germany were evaluated in a Swedish outpatient psychiatric context.

Method

Fifty-one adults with ADHD on stable medical treatment or on no medication were randomized to the DBT-based skills training (n = 26) or a parallel loosely structured discussion group (n = 25). Self-rating scales were administered before randomization and after the treatment.

Results

Feasibility and participant satisfaction were good in both groups while skills training was perceived as more logical and effective for ADHD-related problems. The analyses of the individuals who completed the treatment and remained stable with regard to medication (n = 19 in skills training; n = 18 in control group) showed a significant reduction in ADHD symptoms in the skills training group, but not in the control group. No reduction of comorbidity was observed in any of the groups.

Conclusions

The treatment was feasible in an outpatient psychiatric context, well tolerated, and significantly reduced ADHD symptoms in on-treatment individuals who remained stable regarding medication status.  相似文献

Objective

The aim of this study was to address current gaps in knowledge regarding the appropriateness and quality of counselling provided to egg donors in the UK.

Methods

The present study used a cross-sectional, qualitative design. Semi-structured interviews were carried out with 29 UK egg donors to explore their experiences of egg donation and the counselling received.

Results

Of the 29 participants, 24 had received counselling. The remaining five did not receive counselling because they were either not accepted as a donor (n = 4) or were offered, but chose not to take up the session (n = 1). The findings are presented in relation to five themes: feeling supported via counselling; feeling well-informed; welcoming an individualised approach; the counselling setting; and thinking about the future.

Conclusion

Egg donors in this study had varying experiences of counselling offered to them as part of the egg donation process in the UK.

Implications

The findings indicate that there are some aspects of counselling in the UK that could be improved, including the routine offering of counselling throughout the egg donation process and the tailoring of counselling to meet egg donors' individual needs.  相似文献

Objective

Extend understanding of a rapid response (RR) to treatment by examining its prognostic significance at end-of-treatment (EOT) and 1 year follow-up within two group treatments for binge eating disorder (BED): Dialectical Behavior Therapy for BED (DBT-BED) and an active comparison group therapy (ACGT).

Methods

101 adults with BED randomized to 20-weeks DBT-BED versus ACGT (Safer, Robinson, & Jo, 2010). RR defined as ≥65% reduction in the frequency of days of binge eating by week 4. RR across and within treatment conditions used to predict binge eating abstinence and secondary outcomes (e.g., binge eating pathology, treatment attrition) at EOT and 1 year follow-up.

Results

(1) Significantly higher binge eating abstinence for rapid responders (RR; n = 41) vs. non-rapid responders (non-RRs; n = 60) at EOT (70.7% vs. 33.3%) and 1 year follow-up (70.7% vs. 40.0%), respectively, as well as improvement on most secondary measures (2) Significantly less attrition among RRs vs. non-RRs (3) Significantly higher binge eating abstinence rates at both time points for DBT-RRs vs. DBT-non-RRs, but not for ACGT-RRs vs. ACGT-non-RRs.

Conclusions

Current study extends prognostic significance of RR to 1 year follow-up. RR more prominent for those randomly assigned to DBT-BED than ACGT. Implications discussed.  相似文献

Objectives

In educational contexts, Lent and Lopez (2002) proposed that students develop a tripartite network of efficacy beliefs, comprising their confidence in their own capabilities (i.e., self-efficacy), their confidence in their teacher’s ability (i.e., other-efficacy), and their estimation of their teacher’s confidence in their ability (i.e., relation-inferred self-efficacy). In spite of the potential for school-based physical education (PE) to stimulate leisure-time activity patterns among adolescents, it is noteworthy that this framework has yet to be explored in school PE contexts.

Design and methods

In Phase 1, we recruited 62 Australian high school students (aged 11-13) in order to develop instruments designed to assess self-efficacy, other-efficacy, and relation-inferred self-efficacy within PE settings. In Phases 2 and 3, we sought to provide evidence for measurement reliability, validity, and invariance with cross-sectional and prospective data derived from Australian (N = 602, Mage = 13.54, SD = .76) as well as Singaporean (N = 606; Mage = 14.10, SD = 1.01) students.

Results

Results revealed (a) support for the factorial validity of these measures in both locations, (b) evidence of gender-related and cross-national measurement invariance, (c) positive inter-relationships between students’ tripartite efficacy perceptions that were consistent with theory, and (d) positive correlations with key in-class (e.g., effort, enjoyment) and leisure-time (e.g., physical activity levels) outcomes.

Conclusions

Taken together, the results provide preliminary evidence for the reliability and validity of measures derived from these tripartite efficacy instruments, and support their use in future research designed to examine PE engagement.  相似文献

Fin swimming performance can be divided into underwater and surface water races. World records are about 10% faster for underwater swimming vs. surface swimming, but little is known about the advantage of underwater swimming for monofin swimming. Some authors reported that the air–water interface influences the kinematics and leads to a narrow vertical amplitude of the fin. On the one hand, surface swimming is expected to affect drag parameters (cross-sectional area (S) and active drag (AD)) when compared to underwater swimming. On the other hand, the surface swimming technique may also affect efficiency (ηF). The aim of this study is therefore to evaluate and compare drag parameters and efficiency during underwater and surface swimming. To this end, 12 international level monofin swimmers were measured during both underwater and surface swimming. Kinematic parameters (both dimensional and non-dimensional), ηF (calculated according to the Elongated-Body Theory), and AD (computed with Velocity Perturbation Method) were calculated for an underwater and a surface fin swimming trial, performed at maximal speed. As expected, results showed significantly lower velocities during surface swimming vs. underwater  = 2.5 m s−1 vs.  = 2.36 m s−1, p < .01). Velocities during underwater and surface swimming were strongly correlated (r = .97, p < .01). Underwater swimming was also associated with higher vertical amplitudes of the fin compared to surface swimming ( = 0.55 m vs. ) = 0.46 m, p < .01). Length-specific amplitudes (Aunder/Lb) were in the order of 20% during underwater swimming as for undulating fish, and significantly higher than during surface swimming (Asurf/Lb = 17%, p < .01). Efficiency for surface swimming was about 6% lower than for underwater swimming ( = 0.79 vs.  = 0.74, p < .01). This decrease could be associated with an increase in swimming frequency for surface swimming ( = 2.15 Hz vs.  = 2.08 Hz, p < .01). Active drag during surface swimming was about 7% higher than for underwater swimming ( = 78.9 N vs.  = 84.7 N, p < .01). A significantly smaller cross-sectional area for surface swimming ( = 0.053 m2 vs.  = 0.044 m2, p < .01) and higher drag coefficient for surface swimming ( = 0.47 vs.  = 0.69, p < .01) were measured. Finally, correlation between cross-sectional area and vertical amplitude of the fin was reported for both underwater and surface swimming. These results suggest that the performance improvement during underwater swimming is not only linked to a wave drag reduction effect but also to a specific swimming technique due to the free surface.  相似文献

The present model treats the scaling of pair-comparison preference judgments among a unidimensional set of stimuli across a population of individuals. Given a setS ofn stimuli,S = {S 1,S 2, ,S n }, the model yields a partially ordered metric on the interstimulus distances which may be used to construct an interval scale of values forS. Obtained also are a set of predictionsP = {P 1,P 2, ,P n } whereP i is the proportion of individuals in the population whose first choice among the elements ofS isS i . A numerical illustration is offered and comparisons are drawn with Coombs' unfolding technique.This work was supported in part by Grant GB 2345 from the National Science Foundation.

Monotone regression: Continuity and differentiability properties   总被引:1,自引:0,他引:1  
Least-squares monotone regression has received considerable discussion and use. Consider the residual sum of squaresQ obtained from the least-squares monotone regression ofy i onx i . TreatingQ as a function of they i , we prove that the gradient Q exists and is continuous everywhere, and is given by a simple formula. (We also discuss the gradient ofd=Q 1/2.) These facts, which can be questioned (Louis Guttman, private communication), are important for the iterative numerical solution of models, such as some kinds of multidimensional scaling, in which monotone regression occurs as a subsidiary element, so that they i and hence indirectlyQ are functions of other variables.  相似文献

While research on experimental interventions that aim to improve outgroup attitudes via contact imagery grows, it is important to examine if contact imagery that occurs in spontaneous, non-experimentally controlled conditions drives attitudes, and in what direction. To answer this, we constructed and validated a spontaneous imagined intergroup contact scale (SIICS) that differentiates between frequency, quality and elaboration of the spontaneous imagery of outgroups. In three correlational studies (NPortugal = 305, NUnited Kingdom = 185, NItaly = 276), we tested the role of spontaneous imagined contact frequency, quality and elaboration in predicting attitudes and social distance (Studies 1–3) and intended behaviour (Study 3) toward immigrant groups. Results demonstrated that spontaneous imagined contact quality consistently predicted key outcome variables above and beyond the other two dimensions. Importantly, the effects were significant while controlling for other potent forms of direct and indirect contact. Implications of the findings for theory and practice are discussed.  相似文献

Purpose
  • •Transcranial magnetic stimulation (TMS) provides an indication of changes occurring in the corticospinal pathway. This study aimed to determine the between-day (trials 1 week apart) and within-day (trials 1 h apart) reliability of TMS and peripheral nerve stimulation.
Methods
  • •22 male participants (age 23 ± 4 years; height 1.80 ± 0.07 m; body mass 75.1 ± 11.7 kg; body mass index 23.1 ± 2.5 kg.m−2) completed 2 familiarisation sessions and 3 experimental trials (trial 2 and 3 split by 1 h). The interpolated twitch technique was used to determine TMS-assessed voluntary activations (VA-TMS) superimposed on submaximal and maximal leg extension performed on a custom-built dynamometer. Reliability was assessed using equivalence tests, systematic error, 95% limits of agreement, intraclass correlation coefficient (ICC) and coefficient of variation (CV).
Results
  • •VA-TMS was equivalent between-day (94.1 ± 4.4% versus 93.7 ± 4.9%, P < 0.01) and within-day (93.7 ± 4.9% versus 93.7 ± 4.8%, P < 0.01). Systematic error (95% limits of agreement) for VA-TMS was −0.5% (−5.1%, 4.2%) for between-day and − 0.0% (−5.3%, 5.4%) for within-day. ICC and CV values demonstrated high reliability between-day (ICC = 0.93, CV = 2.5%) and within-day (ICC = 0.92, CV = 2.9%).
Conclusion
  • •Results indicate that TMS can reliably estimate the output of the motor cortex to the knee extensors, both between-day and within-day. The findings have been used to estimate sample sizes for this technique for future research.

In an earlier paper [Psychometrika,31, 1966, p. 147], Srivastava obtained a test for the HypothesisH 0 : = 00 + ... + ll, where i are known matrices,i are unknown constants and is the unknown (p ×p) covariance matrix of a random variablex (withp components) having ap-variate normal distribution. The test therein was obtained under (p ×p) covariance matrix of a random variablex (withp components) the condition that 0, 1, ..., l form a commutative linear associative algebra and a certain vector, dependent on these, has non-negative elements. In this paper it is shown that this last condition is always satisfied in the special situation (of importance in structural analysis in psychometrics) where 0, 1, ..., l are the association matrices of a partially balanced association scheme.This research was partially supported by the U.

Objective

The aim of this study was to examine supervisees' perspectives about the contribution of two predefined aspects of supervision, supervisory bond (SB) and didactic input of supervisor (DI), to their ascribed outcome of therapy.

Method

Supervisees anonymously assessed the SB, supervisors' DI and their contribution to therapy outcome. Assessment was quantitative and qualitative. The supervisory aspects were assessed using a questionnaire constructed for this study. Perceived contribution was evaluated by two scaled questions, and themes generated by an open question. Supervisees (n = 111) evaluated 16 supervisors and supervision’s contribution to psychotherapy outcomes of 111 clients.

Findings

Hierarchical regression showed that supervisees' age, supervisors' status and frequency of supervision accounted for 24% of the variance ascribed to outcome. SB and DI accounted for 51% of the variance. These values, which are higher than reported in the literature, may be attributed to the assessment of predefined aspects of supervision by the same assessor. Thematic analysis of the didactic input produced more themes than for the supervisory bond.

Conclusion

Sociodemographic variables and supervisory relationship variables determine supervisees' evaluations of supervision’s contribution to outcome.

Implications for practice

Training and supervision may benefit from information obtained from quantitative and qualitative measures regarding these and other predefined variables related to supervision. The in-depth look at views and experiences shared by supervisees may advance training, practice and research.  相似文献

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested. We filled this gap by using the Adolescent Brain Cognitive Development study cohort comprising 11,875 children aged 9–10. First, correlations between the age- and sex-specific 95th BMI percentile (%BMIp95) and neurobehavioral measures were cross-sectionally analyzed. Effects were then aggregated by neurobehavioral domain for causal analyses. Behavioral genetic Direction of Causation modeling was used to test the direction of each relationship. Findings were validated by longitudinal cross-lagged panel modeling. %BMIp95 correlated with impulsivity, motivation, psychopathology, eating behavior, and cognitive tests (executive functioning, language, memory, perception, working memory). Greater %BMIp95 was also associated with reduced cortical thickness in frontal and temporal brain areas but with increased thickness in parietal and occipital areas. Similar although weaker patterns emerged for cortical surface area and volume. Behavioral genetic modeling suggested causal effects of %BMIp95 on eating behavior (β = 0.26), cognition (β = 0.05), cortical thickness (β = 0.15), and cortical surface area (β = 0.07). Personality/psychopathology (β = 0.09) and eating behavior (β = 0.16) appeared to influence %BMIp95. Longitudinal evidence broadly supported these findings. Results regarding cortical volume were inconsistent. Results supported causal effects of obesity on brain functioning and morphology. The present study highlights the importance of physical health for brain development and may inform interventions aimed at preventing or reducing pediatric obesity.

Research Highlights

  • A continuous measure related to obesity, %BMIp95, has correlations with various measures of brain functioning and structure
  • Behavioral genetic and longitudinal modeling suggest causal links from personality, psychopathology, and eating behavior to %BMIp95
  • Results also indicate directional links from %BMIp95 to eating behavior, cognition, cortical thickness, and cortical surface area
  • Obesity may play a role for healthy brain development during childhood

Consider the reasonable axioms of subjunctive conditionals (1) if p q 1 and p q 2 at some world, then p (q 1 & q 2) at that world, and (2) if p 1 q and p 2 q at some world, then (p 1p 2) q at that world, where p q is the subjunctive conditional. I show that a Lewis-style semantics for subjunctive conditionals satisfies these axioms if and only if one makes a certain technical assumption about the closeness relation, an assumption that is probably false. I will then show how Lewisian semantics can be modified so as to assure (1) and (2) even when the technical assumption fails, and in fact in one sense the semantics actually becomes simpler then.  相似文献
