The purpose of this study was to compare the effectiveness of and preference for different auditory stimuli in supporting mindfulness meditation. Undergraduate non-musicians ( N = 57) listened to four different auditory stimuli guiding them in a mindfulness meditation: script only (i.e., Script), steady beat (i.e., Beat), beat and harmonic progression (i.e., Harmony), and beat, harmony, and melody (i.e., Melody). This study used a within-subjects repeated-measures design with the four conditions counterbalanced and randomized across participants. Participants rated responses using the Mindful Attention Awareness Scale (MAAS), completed the Absorption in Music Scale (AIMS), and ranked auditory stimuli according to preference and usefulness for mindfulness meditation. A repeated-measures analysis of covariance (ANCOVA) on the MAAS scores, using the AIMS as a covariate, indicated no statistically significant difference between auditory stimuli. However, with the AIMS removed, the analysis revealed significant differences between stimuli, indicating that levels of absorption in music may moderate participants’ responses to auditory stimuli for mindfulness meditation. Friedman analyses of variance (ANOVAs) and post hoc analyses indicated that participant rankings of usefulness and preference were significantly different among conditions, with the Melody and Harmony conditions ranked highest.

Repeated Measures Analysis

The purpose of this study was to compare the effectiveness of and preference for different auditory stimuli on mindfulness meditation in musicians. A second purpose was to compare musician responses with non-musician responses from a previous study. A repeated-measures design exposed participants to four auditory stimuli of increased complexity. Participants ( N = 49) were undergraduate musicians with limited mindfulness experience. Data included absorption in music, mindfulness, and preference and usefulness of auditory stimuli. A repeated-measures analysis of covariance, with absorption of music as a covariate, found no significant differences between stimuli on mindfulness meditation according to musicians. Friedman’s analyses of variance indicated that musician rankings of usefulness and preference were significantly different among conditions. Both musicians and non-musicians ranked Melody and Harmony conditions as most preferred and most useful for mindfulness meditation. A mixed effects model with both groups indicated not only a significant effect of auditory stimuli on mindfulness but also interaction due to group status. A significant result was only obtained when the covariate was not considered. Absorption in music scores between groups was significantly higher for musicians than non-musicians. These outcomes support the hypothesis that absorption in music and music expertise may mediate the effect of a music intervention. Clinical implications are discussed.

Abstract Mindfulness is a natural human capacity to be aware of the present moment, without judgment, rejection, or attachment to it. Cultivating a mindful state has been related to improvements in mood and stress management. Mindfulness practices may be enhanced with music. The purpose of this study was to replicate a previous study regarding the effectiveness, preference, and usefulness of different auditory stimuli for mindfulness practice. Undergraduate nonmusicians (N = 53) listened to 4 different auditory stimuli of increasing complexity, guiding them in a mindfulness experience. Participants rated their mindfulness experience, provided data on their absorption in music, and ranked auditory stimuli according to preference and usefulness for mindfulness practice. A within-subjects design was used to compare the four conditions, counterbalanced, and randomized across participants. Similar to the original study, Friedman analysis of variances (ANOVAs) and post hoc analyses indicated that participants ranked the Melody and Harmony conditions as most preferred and useful. Different from the original results, the repeated-measures ANOVA of the Mindful Attention Awareness Scale scores did not reveal significant differences among auditory stimuli for mindfulness experience. These results provide support for the use of music in mindfulness experiences with a mildly complex stimulus (script, beat, harmony, and melody). However, partially replicated results indicate the need to investigate the discrepancy between participants’ effectiveness ratings and preference/usefulness rankings.

Occlusion Effect

Background: Open canal hearing instruments differ in method of sound delivery to the ear canal, distance between the microphone and the receiver, and physical size of the devices. Moreover, RITA (receiver in the aid) and RITE (receiver in the ear) hearing instruments may also differ in terms of retention and comfort as well as ease of use and care for certain individuals. What remains unclear, however, is if any or all of the abovementioned factors contribute to hearing aid outcome. Purpose: To determine the effect of receiver location on performance and/or preference of listeners using open canal hearing instruments. Research Design: An experimental study in which subjects were exposed to a repeated measures design. Study Sample: Twenty-five adult listeners with mild sloping to moderately severe sensorineural hearing loss (mean age 67 yr). Data Collection and Analysis: Participants completed two six-week trial periods for each device type. Probe microphone, objective, and subjective measures (quiet, noise) were conducted unaided and aided at the end of each trial period. Results: Occlusion effect results were not significantly different between the RITA and RITE instruments; however, frequency range was extended in the RITE instruments, resulting in significantly greater maximum gain for the RITE instruments than the RITA instruments at 4000 and 6000 Hz. Objective performance in quiet or in noise was unaffected by receiver location. Subjective measures revealed significantly greater satisfaction ratings for the RITE than for the RITA instruments. Similarly, preference in quiet and overall preference were significantly greater for the RITE than for the RITA instruments. Conclusions: Although no occlusion differences were noted between instruments, the RITE did demonstrate a significant difference in reserve gain before feedback at 4000 and 6000 Hz. Objectively; no positive benefit was noted between unaided and aided conditions on speech recognition tests. These results suggest that such testing may not be sensitive enough to determine aided benefit with open canal instruments. However, the subjective measures (Abbreviated Profile of Hearing Aid Benefit [APHAB] and subjective ratings) did indicate aided benefit for both instruments when compared to unaided. This further suggests the clinical importance of subjective measures as a way to measure aided benefit of open-fit devices.

AbstractObjective:We provide a closer look at the result of a randomised, placebo-controlled, active-reference (quetiapine XR), flexible-dose, 6-week study of brexpiprazole in schizophrenia, which did not meet its primary endpoint – change from baseline in Positive and Negative Syndrome Scale (PANSS) total score. We also investigate potential expectancy bias from the well-known side-effect profile of the active reference that could have affected the study outcome.Methods:Pre-specified sensitivity analyses of the primary end point were performed using analysis of covariance (ANCOVA) last observation carried forward (LOCF) and observed cases (OC). Post hoc analyses of change from baseline in PANSS total score were performed using the mixed model for repeated measures approach with treatment groups split by having typical adverse events with potential for functional unblinding, for example, somnolence, increase in weight, dizziness, dry mouth and sedation.Results:Pre-specified sensitivity analyses showed separation from placebo for brexpiprazole at week 6: LOCF, ANCOVA: −4.3 [95% CI (−8.0, −0.5), p = 0.0254]. OC, ANCOVA: −3.9 [95% CI (−7.3, −0.5), p = 0.0260]. Patients treated with brexpiprazole experiencing typical adverse events with potential for functional unblinding before or at Week 2 had a least square (LS) mean PANSS change of −29.5 (improvement), with a difference in change from baseline to Week 6 in PANSS total score between brexpiprazole and placebo of −13.5 [95% CI (−23.1, −4.0), p = 0.0057], and those who did not had an LS mean change of −18.9 and a difference between brexpiprazole and placebo of −2.9 [95% CI (−7.2, 1.4), p = 0.1809].Conclusion:Pre-specified sensitivity analyses showed separation from placebo for brexpiprazole at Week 6. A post hoc analysis suggested a potential confounding of efficacy rating towards symptom improvement in patients who experience known side effects of quetiapine XR.

Respiratory Outcomes

Neuromuscular disorders (NMD) lead to the progressive loss of motor and respiratory functions and a decline in daily activities and participation. We aimed to evaluate respiratory changes and functional outcomes in children attending an aquatic therapy program. Eleven patients diagnosed with NMD (4–18 years, Vignos scale 1–9) were involved in a 10-week aquatic exercise program. The ventilation variables were: peak cough flow, volumes (forced expiratory volume in one second-FEV1 and inspiratory volume) and respiratory pressures to evaluate strength and oxygen saturation (O2 sat). Functional skills were measured in the aquatic environment (Water Orientation Test Alyn 1) and on dry land, (Pediatric Evaluation of Disability Inventory), together with quality of life (Pediatric Quality of Life Inventory). Our evaluation included several 2 × 6 mixed-model repeated measures analysis of covariance (ANCOVA) with time (baseline, post 1 session, pre-post at five weeks and pre-post at 10 weeks). Important improvements in functional skills were observed in and out of the water and children under the age of 11 displayed a significant difference for inspirational volume (p = 0.002) and O2 sat (p = 0.029). Clinical, statistically insignificant changes were found for peak cough flow and expiratory pressures values after aquatic exercise. These results may support a relationship between aquatic exercise in NMD, respiratory outcomes and functional activities in water and on land.

There are many studies showing acute static stretching to be detrimental to power generation. However, the majority have focused upon the impact of stretching the agonist musculature. To date, few have examined the potential benefits of acute antagonist static stretching; none have focused on upper-body power. Utilising a repeated-measures design, 30 male participants were randomly assigned to one of two groups whereupon they performed four bench-throw tests; two control (NO-STRETCH) and two experimental (STRETCH), in a counter-balanced manner. Prior to the experimental measures, participants undertook a series of static antagonist stretches. Mean Pmax (SD) in the NO-STRETCH trials was 862.76 (146)W and 898.50 (144)W, respectively. For STRETCH trial 1, Pmax = 930.10 (146)W and trial 2, Pmax = 953.36 (136)W. When compared to the respective NO-STRETCH trials, antagonist static stretching did have a significant effect on Pmax for both the initial ( P < 0.01, d = 1.33) and the re-stretching procedures ( P < 0.01, d = 1.35). A significant difference was also found between the STRETCH trials ( P < 0.01, d = 0.46). The results have practical implications for those involved in upper-body power activities. Specifically, incorporating upper-body antagonist static stretching into pre-performance routines might offer a simple and effective means of enhancing agonist power.

Mindfulness meditation has frequently used sound and music as an important component. However, research on effective music stimuli is scarce. After a series of studies evaluating the most effective, useful, and preferred auditory stimuli, we were interested in exploring whether these effective musical features were transferred to new music. In this study, we evaluate our original music stimuli with three new stimuli composed under similar principles. Non-musician and musician participants ( N = 114) in a multisite study evaluated their mindfulness state after listening to four music stimuli, and rated their usefulness and preference. Results from a repeated-measures analysis of variance (ANOVA) at each site indicated no significant difference in mindfulness effectiveness. Friedman’s ANOVAs for the usefulness of the music stimuli showed similar non-significant results in both sites. A mixed model among sites did not show significant differences among groups. Preference rankings were not significantly different for non-musicians, but musicians did show a statistically significant preference of the Original stimuli over Stimulus 2, probably due to sound quality. These results indicate the feasibility of transferring previously researched and effective musical features to new stimuli. Identifying the effective “active ingredients” of music interventions may be one way of supporting evidence-based practice in music therapy.

Depression rates in collegiate student-athletes in the literature are varied and inconclusive, and data have only explored depression symptoms utilizing a crosssectional design. The purpose of the current study was to evaluate the temporal course of depression symptoms in student-athletes. Student-athletes (N = 93) from a Division II institution completed six administrations of a brief depression symptom screen once every 2 weeks throughout the fall athletic season. Ten (10.8%) student-athletes’ PHQ-9 surveys were red-flagged for moderate to severe depression symptoms at least once throughout the season. A mixed between-within subjects analysis of variance (ANOVA) revealed a significant interaction effect for time and sex in depression symptom scores, F(3.69, 335.70) = 10.36, p ≤ .001. The repeated-measures design of this study suggests that there are clinical benefits for screening for depression symptoms in student-athletes at multiple intervals throughout an athletic season.

AbstractBackgroundSex dialogue is one of the most critical and challenging topics between mothers and adolescents. The knowledge and skills of mothers in sex dialogue with their daughters are essential. The purpose of this study is to determine the effect of group counseling based on communication skills on mothers through their sex dialogue with their daughters.MethodsA randomized controlled field trial was conducted on 168 couples of mothers and their daughters selected by the stratified matching method and randomly divided into two control and intervention groups. The mothers in the intervention group participated in a communication-based consultation in groups consisting of 6–12 people for 6–7 weekly sessions, each one lasting 60 min. The data collection tool was a Persian-translated questionnaire by Jaccard for sex dialogue between mother and daughter. The data were analyzed using Chi-square (χ2), ANOVA with repeated measures and modified post hoc Bonferroni tests.ResultsThere was a significant difference in the mean score of mother-daughter sex dialogue 1 week after intervention between the intervention (34.48 ± 8.74) and control (40.44 ± 9.49) groups (p = 0.001) and 1 month after the intervention between the intervention (30.41 ± 10.07) and control (42.47 ± 9.62) groups (p < 0.001).ConclusionThrough applying communication skills, an increase in mother-daughter sex dialogue frequency was observed after group counseling. Therefore, it is suggested to promote mother-daughter communication skills by accessing the mothers via schools, health centers and with the aid of midwifery counselors, midwives and other trained caretakers.

Stretching Exercises

Although warm-up and stretching exercises are routinely performed by gymnasts, it is suggested that stretching immediately prior to an activity might affect negatively the athletic performance. The focus of this investigation was on the acute effect of a protocol, including warm-up and static and dynamic stretching exercises, on speed during vaulting in gymnastics. Eleven boys were asked to perform three different protocols consisting of warm-up, warm-up and static stretching and warm-up and dynamic stretching, on three nonconsecutive days. Each protocol was followed by a “handspring” vault. One-way analysis of variance for repeated-measures showed a significant difference in gymnasts’ speed, following the different protocols. Tukey’s post hoc analysis revealed that gymnasts mean speed during the run of vault was significantly decreased after the application of the static stretching protocol. The findings of the present study indicate the inhibitory role of an acute static stretching in running speed in young gymnasts.
