ARE PERSONS WITH NERVOUS HABITS NERVOUS? A PRELIMINARY EXAMINATION OF HABIT FUNCTION IN A NONREFERRED POPULATION

In this study, 44 individuals were exposed to three conditions (anxiety, bored, and neutral) while being covertly videotaped. The videotapes were then scored for the occurrence of five classes of habits including hair, face, and object manipulation; object mouthing; and repetitive movement of the limbs. Results showed that hair and face manipulation increased during the anxiety condition, whereas object manipulation increased in the bored condition. The implications of this research are discussed.     

The effects of different adults as therapists during functional analyses

The differential effects of caregivers and inpatient staff members as therapists on behavior were evaluated within a reversal design. Results indicated that problem behaviors were higher in the presence of caregivers relative to inpatient staff. These results are discussed in terms of how antecedent stimuli can affect functional analysis outcomes.     

School-Based Mental Health Services: A Research Review

This paper provides a synthetic review of research on school-based mental health services. Schools play an increasingly important role in providing mental health services to children, yet most school-based programs being provided have no evidence to support their impact. A computerized search of references published between 1985 and 1999 was used to identify studies of school-based mental health services for children. Study inclusion was determined by (i) use of randomized, quasi-experimental, or multiple baseline research design; (ii) inclusion of a control group; (iii) use of standardized outcome measures; and (iv) baseline and postintervention outcome assessment. The application of these criteria yielded a final sample of 47 studies on which this review is based. Results suggest that there are a strong group of school-based mental health programs that have evidence of impact across a range of emotional and behavioral problems. However, there were no programs that specifically targeted particular clinical syndromes. Important features of the implementation process that increase the probability of service sustainability and maintenance were identified. These include (i) consistent program implementation; (ii) inclusion of parents, teachers, or peers; (iii) use of multiple modalities; (iv) integration of program content into general classroom curriculum; and (v) developmentally appropriate program components. Implications of these findings and directions for future research are discussed.     

Long-term efficacy of exercise across diagnostically heterogenous mental disorders and the mediating role of affect regulation skills

BackgroundExercise interventions are efficacious in reducing disorder-specific symptoms in various mental disorders. However, little is known about long-term transdiagnostic efficacy of exercise across heterogenous mental disorders and the potential mechanisms underlying treatment effects.MethodsPhysically inactive outpatients, with depressive disorders, anxiety disorders, insomnia or attention deficit hyperactivity disorder were randomized to a standardized 12-week exercise intervention, combining moderate exercise with behavior change techniques (BCTs) (n = 38), or a passive control group (n = 36). Primary outcome was global symptom severity (Symptom Checklist-90, SCL-90-R) and secondary outcomes were self-reported exercise (Physical Activity, Exercise, and Sport Questionnaire), exercise-specific affect regulation (Physical Activity-related Health Competence Questionnaire) and depression (SCL-90-R) assessed at baseline (T1), post-treatment (T2) and one year after post-treatment (T3). Intention-to-treat analyses were conducted using linear mixed models and structural equations modeling.ResultsFrom T1 to T3, the intervention group significantly improved on global symptom severity (d = −0.43, p = .031), depression among a depressed subsample (d = −0.62, p = .014), exercise (d = 0.45, p = .011) and exercise-specific affect regulation (d = 0.44, p = .028) relative to the control group. The intervention group was more likely to reveal clinically significant changes from T1 to T3 (p = .033). Increases in exercise-specific affect regulation mediated intervention effects on global symptom severity (ß = −0.28, p = .037) and clinically significant changes (ß = −0.24, p = .042).ConclusionsThe exercise intervention showed long-term efficacy among a diagnostically heterogeneous outpatient sample and led to long-lasting exercise behavior change. Long-term increases in exercise-specific affect regulation within exercise interventions seem to be essential for long-lasting symptom reduction.     

Surf therapy for improving child and adolescent mental health: A pilot randomised control trial

The aim of this pilot randomised control trial (RCT) was to test, 1) feasibility and acceptability of a surf therapy program to improve symptoms of mental ill-health among children and adolescents, and 2) the design and procedures of an evaluative study. This pilot RCT compared a 6-week mentor-supported surf therapy program with a wait list control group, in Australian children and adolescents aged 8–18yrs (M age = 11.28, SD = 2.34; 15 females), who were help seeking for issues relating to their mental health. Exclusion criteria included if an individual was actively suicidal or experiencing a psychotic episode or being unavailable for program dates. The primary outcome was the feasibility and acceptability of the intervention and study design assessed via 11 pre-defined criteria. A secondary outcome was to investigate the effectiveness signal of the intervention on child indicators of depression and anxiety, assessed via the Revised Children’s Anxiety and Depression Scale-Short Form and the Strengths and Difficulties Questionnaire. Random allocation was computer generated and while it was not possible to blind participants, researchers collecting assessments were blinded to group allocation. Thirty-six youth were randomised (intervention = 18; wait list controls = 18), representing an 84% participation rate among eligible youth. Of the 11 a priori feasibility and acceptability criteria, 4 of 5 relating to the intervention, and 4 of 6 addressing the study design were fully met, with the unmet factors guiding program revision. At the completion of the intervention, children and adolescents receiving the intervention reported reductions in symptoms of depression (ES = 0.57), anxiety (ES = 0.43), emotional problems, (ES = 0.79), peer problems (ES = 0.56), hyperactivity/inattention (ES = 0.28), and overall difficulties (ES = 0.64). These reductions were not sustained 6-weeks after completion of the intervention. Surf therapy is an acceptable and feasible intervention for addressing symptoms of mental ill-health among children and adolescents. Preliminary evidence suggests that surf therapy improves symptoms of mental ill-health in the short-term but that these improvements were not sustained after the intervention is ceased.     

Mediation of the stigma in the influence of negative symptomatology over recovery in psychosis

Background/Objective: The interest in recovery processes in psychotic disorders has boosted the necessity of knowledge about the factors that could influence in such recovery. Negative symptomatology and the stigma have been negatively linked to the recovery process in psychosis. The aim of this investigation is to improve the understanding of how the recovery process is affected by negative symptomatology based on the analysis of the mediating effects of the internalized stigma. Method: The sample was composed of 114 people that had experienced, at some point in their life, at least one clinically relevant psychotic episode. CAPE-42, STORI and ISMI were used for the evaluation. The macro PROCESS for SPSS was used. The indirect effect was calculated using 10.000 samples of bootstrap for the bootstrap confidence intervals (IC) corrected for bias. Results: The results show that the influence of negative symptomatology predicts the stigmatization of the person regarding his disorder. This predicts a negative influence in the recovery process of the psychosis. Conclusions: These results back the importance of adding the reduction of the stigma as a specific strategy to improve the recovery process in psychotic disorders.

本研究采用《幼儿数感测评量表》对26名自闭症谱系障碍（autism spectrum disorders,ASD）幼儿、20名智力障碍幼儿及32名正常幼儿进行数感能力测评,并比较三组幼儿的数感特点。结果发现：（1）ASD幼儿的数感整体和各维度水平均显著低于正常幼儿,但与智力障碍幼儿相当;（2）三组幼儿数感各维度水平在5～7岁之间无明显变化;（3）三组幼儿在数量比较、数量估算和大小比较的能力水平均领先于其他维度,而类比推理和大小推理均相对落后。另外,ASD幼儿和智力障碍幼儿的体积比较与大小推理、类比推理的能力较为接近,而正常幼儿的体积比较能力显著优于大小推理和类比推理。研究表明5～7岁ASD幼儿的数感能力整体落后于同龄正常幼儿,且数感各维度的能力发展不均衡、不同步。本研究揭示了5～7岁ASD幼儿数感能力发展的特点及需求,可为制定相应数感干预方案、促进其数学学习提供参考。     

Benefits of recreational dance and behavior analysis for individuals with neurodevelopmental disorders: A literature review

Dance can be an entertaining experience that offers multiple benefits for those who participate. Unlike typically developing populations, studies examining benefits of recreational dance for individuals with neurodevelopmental disorders are limited. In this review, we conducted a literature search, where “dance” was cross‐listed with all neurodevelopmental disorders across five databases, yielding 19 articles. Twelve studies involved children and youth with neurodevelopmental disorders aged 3–19 years, two studies included both adolescents and adults aged 14–22 years, and five studies included adults aged 20–65 years. Given the effectiveness of applied behavior analysis in enhancing skill development, it is encouraging that eight studies explicitly identified behavioral components. Results suggest potential benefits of recreational dance across studies using self‐report and objective measures, but limited research with sound methodology exists. There is a need for controlled research with measurable outcomes to evaluate programs tailored to these populations to improve core challenges and secondary outcomes such as quality of life.     

Conscious intention and human action: Review of the rise and fall of the readiness potential and Libet’s clock

Is consciousness—the subjective awareness of the sensations, perceptions, beliefs, desires, and intentions of mental life—a genuine cause of human action or a mere impotent epiphenomenon accompanying the brain’s physical activity but utterly incapable of making anything actually happen? This article will review the history and current status of experiments and commentary related to Libet’s influential paper (Brain 106:623–664, 1983) whose conclusion “that cerebral initiation even of a spontaneous voluntary act …can and usually does begin unconsciously” has had a huge effect on debate about the efficacy of conscious intentions. Early (up to 2008) and more recent (2008 on) experiments replicating and criticizing Libet’s conclusions and especially his methods will be discussed, focusing especially on recent observations that the readiness potential (RP) may only be an “artifact of averaging” and that, when intention is measured using “tone probes,” the onset of intention is found much earlier and often before the onset of the RP. Based on these findings, Libet’s methodology was flawed and his results are no longer valid reasons for rejecting Fodor’s “good old commonsense belief/desire psychology” that “my wanting is causally responsible for my reaching.”.     

Investigating the validity of the Perceptual Awareness Scale – The effect of task-related difficulty on subjective rating

The Perceptual Awareness Scale (PAS) is often used to probe conscious experience, but the assumptions behind the scale and its validity are rarely tested. Using a continuous colour estimation task to assess perceptual quality, we focus on how well PAS follows perceptual quality and how the presence of the estimation task affects PAS ratings. We varied the number and presentation time of stimuli in a simultaneous presentation and target position in a sequential presentation. In all experiments, PAS rating closely followed colour precision. However, it was affected by task-induced response bias, even when the possible task difficulty was judged, without performing the task itself. Still, this bias was only observed on the absolute rating level rather than the scale's ability to capture changes in perceptual quality. Reported studies shed light on factors influencing scales outside of the scale formulation and construction.
