Profiling Movement and Gait Quality Characteristics in Pre-School Children

There is a dearth of suitable metrics capable of objectively quantifying motor competence. Further, objective movement quality characteristics during free play have not been investigated in pre-school children. The aims of this study were to characterize children's free play physical activity and investigate how gait quality characteristics cluster with free play in pre-school children (3–5 years old). Sixty-one children (39 boys; 4.3 ± 0.7 years, 1.04 ± 0.05 m, 17.8 ± 3.2 kg) completed the movement assessment battery for children and took part in free play while wearing an ankle- and hip-mounted accelerometer. Characteristics of movement quality were profiled using a clustering algorithm. Spearman's rho and the Mann-Whitney U tests were used to assess relationships between movement quality characteristics and motor competence classification differences in integrated acceleration and spectral purity, respectively. Significant differences were found between motor competency classifications for spectral purity and integrated acceleration (p < .001). Spectral purity was hierarchically clustered with motor competence and integrated acceleration. Significant positive correlations were found between spectral purity, integrated acceleration and motor competence (p < .001). This is the first study to report spectral purity in pre-school children and the results suggest that the underlying frequency component of movement is clustered with motor competence.     

A Feasibility Trial of Mental Health First Aid First Nations: Acceptability,Cultural Adaptation,and Preliminary Outcomes

The Mental Health First Aid First Nations course was adapted from Mental Health First Aid Basic to create a community‐based, culturally safe and relevant approach to promoting mental health literacy in First Nations contexts. Over 2.5 days, the course aims to build community capacity by teaching individuals to recognize and respond to mental health crises. This feasibility trial utilized mixed methods to evaluate the acceptability, cultural adaptation, and preliminary effectiveness of MHFAFN. Our approach was grounded in community‐based participatory research principles, emphasizing relationship‐driven procedures to collecting data and choice for how participants shared their voices. Data included participant interviews (n = 89), and surveys (n = 91) from 10 groups in four provinces. Surveys contained open‐ended questions, retrospective pre‐post ratings, and a scenario. We utilized data from nine facilitator interviews and 24 facilitator implementation surveys. The different lines of evidence converged to highlight strong acceptability, mixed reactions to the cultural adaptation, and gains in participants’ knowledge, mental health first aid skill application, awareness, and self‐efficacy, and reductions in stigma beliefs. Beyond promoting individual gains, the course served as a community‐wide prevention approach by situating mental health in a colonial context and highlighting local resources and cultural strengths for promoting mental well‐being.     

Maltreated Children Use More Grammatical Negations

Many studies reveal a strong impact of childhood maltreatment on language development, mainly resulting in shorter utterances, less rich vocabulary, or a delay in grammatical complexity. However, different theories suggest the possibility for resilience—a positive adaptation to an otherwise adverse environment—in children who experienced childhood maltreatment. Here, we investigated different measures for language development in spontaneous speech, examining whether childhood maltreatment leads to a language deficit only or whether it can also result in differences in language use due to a possible adaptation to a toxic environment. We compared spontaneous speech during therapeutic peer-play sessions of 32 maltreated and 32 non-maltreated children from the same preschool and equivalent in gender, age (2 to 5 years), home neighborhood, ethnicity, and family income. Maltreatment status was reported by formal child protection reports, and corroborated by independent social service reports. We investigated general language sophistication (i.e., vocabulary, talkativeness, mean length of utterance), as well as grammatical development (i.e., use of plurals, tense, grammatical negations). We found that maltreated and non-maltreated children showed similar sophistication across all linguistic measures, except for the use of grammatical negations. Maltreated children used twice as many grammatical negations as non-maltreated children. The use of this highly complex grammatical structure shows an advanced linguistic skill, which shows that childhood maltreatment does not necessarily lead to a language deficit. The result might indicate the development of a negativity bias in the structure of spontaneous language due to an adaptation to their experiences.     

Women’s Introduction to Alternative Sexual Behaviors through Erotica and Its Association with Sexual and Relationship Satisfaction

Women’s interests in bondage, discipline, dominance/submission, and sadism/masochism (BDSM) behaviors are one of the most poorly understood research topics, even though erotica novels—typically read by women—are increasingly including these activities. The present study explored potential links between women’s engagement in BDSM behaviors, consumption of erotica literature, relationship communication and satisfaction, and overall well-being using a multi-study approach. Results from three exploratory studies using multiple methodologies revealed a positive association between erotica, BDSM behaviors, and physical satisfaction, but brought attention to the relatively little information available for women who are interested in practicing alternative sexual behaviors. Practical suggestions for social scientists and mental health professionals are provided.     

Revisiting a meta-analysis of helpful aspects of therapy in a community counselling service

This small scale mixed methods study examines helpful events in a community counselling setting, categorising impacts of events according to Timulak’s [(2007). Identifying core categories of client-identified impact of helpful events in psychotherapy: A qualitative meta-analysis. Psychotherapy Research, 17, 305–314] meta-synthesis of significant events research. Comparisons were made between the types of impacts reported as helpful by clients receiving cognitive behavioural therapy (CBT) or relational integrative counselling. Seventy-five clients identified 291 significant events on 216 Helpful Aspects of Therapy (HAT) forms. The findings broadly reflect all nine impacts identified by Timulak (2007). The study also suggests that a potential new category, ‘voicing’ may exist. Differences between the types of impacts reported as helpful by clients in CBT and integrative therapy showed a higher percentage of CBT clients reporting ‘behavioural change/problem solution’, ‘reassurance’ and ‘client involvement’ as helpful. Differences in other categories were not statistically significant.     

All for one or some for all? Evaluating informative hypotheses using multiple <Emphasis Type="Italic">N</Emphasis> = 1 studies

Analyses are mostly executed at the population level, whereas in many applications the interest is on the individual level instead of the population level. In this paper, multiple N =?1 experiments are considered, where participants perform multiple trials with a dichotomous outcome in various conditions. Expectations with respect to the performance of participants can be translated into so-called informative hypotheses. These hypotheses can be evaluated for each participant separately using Bayes factors. A Bayes factor expresses the relative evidence for two hypotheses based on the data of one individual. This paper proposes to “average” these individual Bayes factors in the gP-BF, the average relative evidence. The gP-BF can be used to determine whether one hypothesis is preferred over another for all individuals under investigation. This measure provides insight into whether the relative preference of a hypothesis from a pre-defined set is homogeneous over individuals. Two additional measures are proposed to support the interpretation of the gP-BF: the evidence rate (ER), the proportion of individual Bayes factors that support the same hypothesis as the gP-BF, and the stability rate (SR), the proportion of individual Bayes factors that express a stronger support than the gP-BF. These three statistics can be used to determine the relative support in the data for the informative hypotheses entertained. Software is available that can be used to execute the approach proposed in this paper and to determine the sensitivity of the outcomes with respect to the number of participants and within condition replications.     

Does a Judicial Warning Improve Defendant‐Culprit Matching?

During a trial, jurors may be asked to compare the defendant with video of the culprit. Yet matching unfamiliar people in this manner can be difficult and error‐prone. Judges may warn jurors about the dangers of identification from video images, but the effect of warnings is unknown. Here we report two studies that assessed the effect of warning instructions on defendant‐culprit matching. In Experiment 1, college students read either control, warning, or illustrated warning instructions before deciding if a defendant seen in one video matched the culprit in another video. Experiment 2 compared control and warning instructions in a sample of Amazon Mechanical Turk workers. Matching accuracy in both experiments was poor, and warnings did not consistently improve performance or make participants more cautious. These results do not support the supposition that warning instructions help jurors compare the defendant to images of the culprit.Copyright © 2016 John Wiley & Sons, Ltd.
