Parental perceptions of genetic testing for children with autism spectrum disorders

Children with autism spectrum disorder (ASD) routinely undergo genetic testing (GT) to identify the causative genetic etiology of their ASD. As there are questions about the impact of GT beyond clinical diagnosis, we conducted a mixed methods study to assess the perceived benefits of GT by exploring factors that lead parents to pursue these tests and the benefits experienced. Respondents were part of a pretest or posttest group. The pretest group (N = 22) expressed intent to pursue GT and the posttest group (N = 32) had undergone GT and received results at least 3 months prior to completing the survey. Responses were compared between and within groups. Free text responses were coded for themes and selection questions were analyzed using Fisher's exact tests. Our results demonstrate significant differences between the groups with participants in the pretest group more likely to choose “increased access to therapies” (p = 0.026) and “improved healthcare” (p < 0.000) as reasons to pursue testing. Benefits were also significantly different with “improved healthcare” (p = 0.009), “improved access to services” (p = 0.012), and “improved access to therapies” (p = 0.003) more frequently anticipated by the pretest group than reported by the posttest group. A relationship between GT and clinical management changes was reported by 34.4–50.0% of the posttest group. Among that group, genetic result type (positive, negative, or variant of uncertain significance) was associated with differing perceived benefits of testing. Thematic analysis revealed increased knowledge and coping as reported benefits in both groups. Our findings indicate a discrepancy between parental expectations and experiences of GT. Comprehensive pretest and posttest genetic counseling are necessary to improve information retention, address potential outcomes, and set expectations of GT for parents of children with ASD.     

Patient knowledge and recall of health information following exposure to “facts and myths” message format variations

Objective

To assess if exposure to varying “facts and myths” message formats affected participant knowledge and recall accuracy of information related to influenza vaccination.

Methods

Consenting patients (N = 125) were randomized to receive one of four influenza related messages (Facts Only; Facts and Myths; Facts, Myths, and Refutations; or CDC Control), mailed one week prior to a scheduled physician visit. Knowledge was measured using 15 true/false items at pretest and posttest; recall accuracy was assessed using eight items at posttest.

Results

All participants’ knowledge scores increased significantly (p < 0.05); those exposed to the CDC Control message had a higher posttest knowledge score (adjusted mean = 11.18) than those in the Facts Only condition (adjusted mean 9.61, p = <0.02). Participants accurately recalled a mean of 4.49 statements (SD = 1.98). ANOVA demonstrated significant differences in recall accuracy by condition [F(3, 83) = 7.74, p < .001, η² = 0.22].

Conclusion

Messages that include facts, myths, and evidence to counteract myths appear to be effective in increasing participants’ knowledge. We found no evidence that presenting both facts and myths is counterproductive to recall accuracy.

Practice implications

Use of messages containing facts and myths may engage the reader and lead to knowledge gain. Recall accuracy is not assured by merely presenting factual information.     

Climacteric symptoms and quality of life in yoga practitioners

BackgroundYoga is among the most commonly studied complementary therapies for managing climacteric symptoms. However, it is unclear whether yoga practices in premenopause can affect the occurrence of symptoms when women reach menopause.ObjectiveTo assess climacteric symptoms and quality of life in regular yoga practitioners and to determine whether yoga practices before menopause may avoid or mitigate climacteric-related symptoms.DesignThis study of 108 women between 40 and 65 years old included 28 women who started to practice yoga in premenopause and had already practiced for at least five years, and as controls 30 physical activity practitioners (PA) who had practiced for at least five years, and 50 sedentary women.Main outcome measuresClimacteric symptoms were evaluated with the Kupperman Menopausal Index (KMI) and the Women's Health Questionnaire (WHQ). Moreover, we measured the quality of life with the WHQ.ResultsThe KMI showed that 39.3% of yoga practitioners had no menopausal symptoms, and none reported severe symptoms. The WHQ indicated a few symptoms and a good quality of life for yoga practitioners (3.56; 3.35–3.80). In addition, we found that the yoga group had significantly less moderate and severe symptoms (p = 0.002) compared with the sedentary group. We also observed that yoga practitioners had less vasomotor symptoms and memory/concentration disorders than PA practitioners (p = 0.010 and p = 0.047) and sedentary women (p = 0.001 and p = 0.001) and also used fewer drugs than the PA (p < 0.001) and the sedentary groups (p = 0.001).ConclusionsYoga practitioners who started to practice in premenopause had satisfactory results on the frequency and intensity of climacteric symptoms and quality of life. Although further research is required to support our findings, we conclude that yoga practice may represent an efficient non-pharmacological approach to manage and prevent climacteric symptoms.     

Effect of yoga on the social responsiveness and problem behaviors of children with ASD in special schools: A randomized controlled trial

ContextAutism spectrum disorder (ASD) is the most common neurodevelopmental disorder and is increasingly reported among school-age children in India. Many children with ASD attend special schools which extend support for learning basic functional and academic skills. Problem behaviors and lack of social responsiveness are frequently associated with children with ASD in a school environment. Many evidence-based studies have explored various interventions in mitigating the lack of social responsiveness and problem behaviors in children. Few studies have examined the impact of yoga on social responsiveness and problem behaviors in special schools.ObjectiveThe objective of the study was to highlight the effect of school-based yoga on the social responsiveness and problem behaviors of children with ASD in special schools. Forty-three children with ASD from four special schools participated in the study.DesignA randomized controlled trial (RCT) design was employed for the study. Children with ASD (n = 43) from four special schools were assessed by their teachers for social responsiveness and problem behaviors with the Social Responsiveness Scale-2 (SRS-2) and Aberrant Behavior Checklist-2 (ABC-2) at the baseline and after the yoga intervention.InterventionStructured yoga of 45 min for 12 weeks was conducted across four special schools with simple yoga practices conducive to children with ASD.ResultsSignificant changes were observed post-intervention in the mean scores of the social communication aspect in social responsiveness (p = .021), irritability (p = .041), and social withdrawal (p = .047) aspects of problem behaviors.     

Elevated perseveration errors on a verbal fluency task in frequent nightmare recallers: a replication

A recent study reported that individuals recalling frequent idiopathic nightmares (NM) produced more perseveration errors on a verbal fluency task than did control participants (CTL), while not differing in overall verbal fluency. Elevated scores on perseveration errors, an index of executive dysfunction, suggest a cognitive inhibitory control deficit in NM participants. The present study sought to replicate these results using a French‐speaking cohort and French language verbal fluency tasks. A phonetic verbal fluency task using three stimulus letters (P, R, V) and a semantic verbal fluency task using two stimulus categories (female and male French first names) were administered to 23 participants with frequent recall of NM (≥2 NM per week, mean age = 24.4 ± 4.0 years), and to 16 CTL participants with few recalled NM (≤ 1 NM per month, mean age = 24.5 ± 3.8 years). All participants were French‐speaking since birth and self‐declared to be in good mental and physical health apart from their NM. As expected, groups did not differ in overall verbal fluency, i.e. total number of correct words produced in response to stimulus letters or categories (P = 0.97). Furthermore, groups exhibited a difference in fluency perseveration errors, with the NM group having higher perseveration than the CTL group (P = 0.03, Cohen's d = 0.745). This replication suggests that frequent NM recallers have executive inhibitory dysfunction during a cognitive association task and supports a neurocognitive model which posits fronto‐limbic impairment as a neural correlate of disturbed dreaming.     

Effects of a parent education program on parents and their preadolescent children

This study assessed the effects of the Survival Training for Parents (STP) program on parental attitudes and on the self-esteem and manifest anxiety of preadolescent children. The STP program presents Adlerian parenting principles in six 2¹/₂-hour sessions to the parents of preadolescents, as an outreach service of a community mental health center. Participants were selected from volunteers from two school districts in northeastern Ohio. Parents in the experimental condition participated in the STP program while control group parents were wait-listed. Eighteen parent-child pairs completed pre and posttesting. Analyses of covariance using the pretest as covariate showed that STP was effective in changing parent attitudes of confidence (p <.01), causation (p <.01), and understanding (p <.05) at posttest. The children of participants in STP improved in self-esteem in school ( p <.05) at posttest. The results are compared to other parent education outcome studies.     

A comparative study of the effects of yoga and clinical Pilates training on walking,cognition, respiratory functions,and quality of life in persons with multiple sclerosis: A quasi-experimental study

ObjectiveThe purpose was to investigate the effects of yoga and clinical Pilates training on walking, respiratory muscle strength, cognition, and quality of life and compare the effects of two popular exercise methods in persons with multiple sclerosis (pwMS).MethodsTwenty-eight pwMS (Pilates group = 16, yoga group = 12) received the program once a week for eight weeks in addition to home exercises. At baseline and the end of the training, participants underwent assessments. The outcome measures were walking speed, mobility, balance confidence, respiratory muscle strength, cognition, and quality of life.ResultsFollowing the program, there was no significant difference in mobility (p = 0.482), perceived walking quality (p = 0.325), respiratory muscle strength (maximum inspiratory pressure: p = 0.263, maximum expiratory pressure: p = 0.866), and cognition (Symbol Digit Modalities Test: p = 0.324, California Verbal Learning Test-II: p = 0.514, Brief Visuospatial Memory Test-Revised: p = 0.279) between the two groups. Improvements were higher in balance confidence (p = 0.006), walking speed (p = 0.004), and quality of life (p = 0.019) in the clinical Pilates group compared to the yoga group.ConclusionThis study showed positive effects in walking and respiratory aspects in pwMS who received yoga and clinical Pilates training. Pilates training was superior in improving walking speed, quality of life, and balance confidence compared to yoga training.     

Efficacy of individualized homeopathic medicines in irritable bowel syndrome: A double-blind randomized,placebo-controlled trial

ContextGastrointestinal ailments are some of the common conditions treated in homeopathy; yet only a few trials have explored the effects of individualized homeopathic medicines (IHMs) for irritable bowel syndrome (IBS).ObjectiveTo explore the efficacy of IHMs in treatment of IBS.DesignDouble-blind, randomized, placebo-controlled trial.SettingOutpatient departments of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, India.PatientsSixty patients suffering from IBS; randomized to receive either IHMs (n = 30) or identical-looking placebo (n = 30).InterventionsIHMs or placebo in the mutual context of concomitant care in terms of dietary advice, yoga, meditation and exercises.Main outcome measuresPrimary – IBS quality of life (IBS-QOL) questionnaire; secondary –IBS severity scoring system (IBS-SSS) and EQ-5D-5L scores; all measured at baseline and every month, up to 3 months.ResultsGroup differences and effect sizes (Cohen's d) were calculated on intention-to-treat (ITT) sample. Groups were comparable at baseline. Recruitment, retention and attrition rates were 64.5%, 91.7% and 8.3% respectively. Group differences in IBS-QOL total scores, IBS-SSS, EQ-5D-5L scores favored IHMs against placebo overall and at all the time points (all P < 0.001). Pulsatilla nigricans (n = 4, 6.7%) and Thuja occidentalis (n = 4, 6.7%) were the most frequently prescribed medicines. Barring some minor events unrelated to interventions, no harms or serious adverse events were recorded in either of the groups. Thus, IHMs acted significantly better than placebos in the treatment of IBS. Independent replications are warranted. [Trial registration: CTRI/2019/10/021632]     

Feasibility study of a modified yoga program for chronic pain among elderly adults in assisted and independent living

ContextYoga improves quality of life in elders ≥65 years, but studies among elders with chronic pain are limited.ObjectiveConduct a feasibility study of gentle yoga among elders in assisted and independent living.DesignSingle arm pre/post clinical trial.SubjectsAdults (≥65 years of age) with self-identified chronic pain (≥3 on a 10-point scale, lasting for ≥3 months) and no current yoga practice.InterventionTen weekly 60-min gentle yoga classes tailored to elderly adults.Outcome measuresAt baseline, weeks 5, 10 (end of intervention), and 20 (follow-up), we collected data on feasibility (adherence, retention, safety), pain, anxiety, depression, fatigue, sleep disturbance, and physical function.ResultsTwenty-six participants enrolled (88% women, 77% white, 58% in assisted living) with average age of 86.6 ± 4.4 (Mean, STD). Twenty participants completed the intervention, with 90% adhering (completing ≥6 classes). Nine participants (45% of completers) experienced adverse events, which were non-serious and related to transient musculoskeletal pain. No adverse events resulted in study withdrawal. Participants reported being somewhat likely to recommend yoga to a friend, and quite a bit likely to do yoga again. At the end of the intervention, four of twenty participants reported practicing yoga outside of class. Anxiety significantly decreased from 5.80 (SE=0.90) to 4.44 (SE=0.74) (p = 0.014), but there were no changes in other measures.ConclusionsOur pilot 10-week yoga study was generally safe for and suitable to assisted and independent living elderly adults. Future studies are needed to examine other effects of yoga in assisted/independent living adults with chronic pain.     

Examining the Gap Between Medical School Matriculation and Graduation Rates Amongst Self-Identified Minorities

PurposeDespite increasing diversity, data indicates that there is a gap between the matriculation or admission of and graduation rates amongst medical students who identify with racial or ethnic minority groups. The purpose of this study was to identify barriers experienced by minority medical students that may account for this gap.MethodsAn IRB approved online survey was created, and distributed electronically to minority medical students, residents, and practicing physicians. Information on demographics, family dynamics, academic struggles, health issues, financial difficulties and faculty diversity was collected via self-report.ResultsParticipants (n = 167) who completed the survey identified as Black/African/African American (60%), Hispanic/Latinx (26%), Asian (8%), and as Other racial or ethnic minority (6%). The majority of survey participants graduated within the traditional 4 years of medical school (83%) and 17% did not. The most frequently reported reason was to pursue academic advancement (42%) which included completing a research year, dual degree, or PhD. The second reason was due to academic deficiencies (38%), either course failure or failure of a board exam. The majority of respondents (59%) also reported not having enough faculty members who were members of racial or ethnic minority groups at their medical school.ConclusionsOur data suggests the majority of racial and ethnic minority medical students graduate within the traditional 4 years of medical school. However, if they do not, it is either due to academic advancement to become a more successful residency applicant, or due to academic issues. The majority of respondents reported that they perceive a lack of racial and ethnic minority faculty members in academics.     

Yoga for asthma: a systematic review and meta-analysis

BackgroundAlthough yoga is frequently used by patients with asthma, its efficacy in alleviating asthma remains unclear.ObjectiveTo systematically assess and meta-analyze the available data on efficacy and safety of yoga in alleviating asthma.MethodsMEDLINE/PubMed, Scopus, the Cochrane Central Register of Controlled Trials, PsycINFO, CAM-Quest, CAMbase, and IndMED were searched through January 2014. Randomized controlled trials of yoga for patients with asthma were included if they assessed asthma control, symptoms, quality of life, and/or pulmonary function. For each outcome, standardized mean differences (SMDs) or risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. Risk of bias was assessed using the Cochrane tool.ResultsFourteen randomized controlled trials with 824 patients were included. Evidence for effects of yoga compared with usual care was found for asthma control (RR, 10.64; 95% CI, 1.98 to 57.19; P = .006), asthma symptoms (SMD, −0.37; 95% CI, −0.55 to −0.19; P < .001), quality of life (SMD, 0.86; 95% CI, 0.39 to 1.33; P < .001), peak expiratory flow rate (SMD, 0.49; 95% CI, 0.32 to 0.67; P < .001), and ratio of forced expiratory volume in 1 second to forced vital capacity (SMD, 0.50; 95% CI, 0.24 to 0.75; P < .001); evidence for effects of yoga compared with psychological interventions was found for quality of life (SMD, 0.61; 95% CI, 0.22 to 0.99; P = .002) and peak expiratory flow rate (SMD, 2.87; 95% CI, 0.14 to 5.60; P = .04). No evidence for effects of yoga compared with sham yoga or breathing exercises was revealed. No effect was robust against all potential sources of bias. Yoga was not associated with serious adverse events.ConclusionYoga cannot be considered a routine intervention for asthmatic patients at this point. It can be considered an ancillary intervention or an alternative to breathing exercises for asthma patients interested in complementary interventions.     

Web-Based Cognitive Behavioral Therapy for Female Patients With Eating Disorders: Randomized Controlled Trial

Background

Many patients with eating disorders do not receive help for their symptoms, even though these disorders have severe morbidity. The Internet may offer alternative low-threshold treatment interventions.

Objective

This study evaluated the effects of a Web-based cognitive behavioral therapy (CBT) intervention using intensive asynchronous therapeutic support to improve eating disorder psychopathology, and to reduce body dissatisfaction and related health problems among patients with eating disorders.

Methods

A two-arm open randomized controlled trial comparing a Web-based CBT intervention to a waiting list control condition (WL) was carried out among female patients with bulimia nervosa (BN), binge eating disorder (BED), and eating disorders not otherwise specified (EDNOS). The eating disorder diagnosis was in accordance with the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and was established based on participants’ self-report. Participants were recruited from an open-access website, and the intervention consisted of a structured two-part program within a secure Web-based application. The aim of the first part was to analyze participant’s eating attitudes and behaviors, while the second part focused on behavioral change. Participants had asynchronous contact with a personal therapist twice a week, solely via the Internet. Self-report measures of eating disorder psychopathology (primary outcome), body dissatisfaction, physical health, mental health, self-esteem, quality of life, and social functioning were completed at baseline and posttest.

Results

A total of 214 participants were randomized to either the Web-based CBT group (n=108) or to the WL group (n=106) stratified by type of eating disorder (BN: n=44; BED: n=85; EDNOS: n=85). Study attrition was low with 94% of the participants completing the posttest assignment. Overall, Web-based CBT showed a significant improvement over time for eating disorder psychopathology (F ₉₇=63.07, P<.001, d=.82) and all secondary outcome measures (effect sizes between d=.34 to d=.49), except for Body Mass Index. WL participants also improved on most outcomes; however, effects were smaller in this group with significant between-group effects for eating disorder psychopathology (F ₂₀₁=9.42, P=.002, d=.44), body dissatisfaction (F ₂₀₁=13.16, P<.001, d=.42), physical health (F ₂₀₀=12.55, P<.001, d=.28), mental health (F ₂₀₃=4.88, P=.028, d=.24), self-esteem (F ₂₀₂=5.06, P=.026, d=.20), and social functioning (F ₂₀₅=7.93, P=.005, d=.29). Analyses for the individual subgroups BN, BED, and EDNOS showed that eating disorder psychopathology improved significantly over time among Web-based CBT participants in all three subgroups; however, the between-group effect was significant only for participants with BED (F ₇₈=4.25, P=.043, d=.61).

Conclusions

Web-based CBT proved to be effective in improving eating disorder psychopathology and related health among female patients with eating disorders.

Quasi-stiffness of the knee joint is influenced by walking on a destabilising terrain

BackgroundPredictive models have been devised to estimate the necessary quasi-stiffness that a transfemoral prosthesis should be set to aligning the body and gait parameters of the user. Current recommendations exist only for walking over level ground. This study aimed to ascertain whether walking across destabilising terrain influences the quasi-stiffness of the knee joint thus influencing prosthetic engineering.MethodsTen healthy males (age: 25.1 ± 2.5 years; mean ± sd, height: 1.78 ± 0.05 m, weight: 84.40 ± 11.02 kg) performed 14 gait trials. Seven trials were conducted over even ground and seven over 20 mm ballast. Three-dimensional motion capture and ground reaction force were collected. Paired samples t-tests and Wilcoxon signed ranked test compared variables including; quasi-stiffness, gait speed, stride length and stride width.ResultsQuasi-stiffness (d = 0.562, P = 0.001) and stride width (d = 0.909, P < 0.001) were significantly greater in the destabilising terrain condition. Gait speed (r = −0.731, P = 0.001) was significantly greater in the control condition. No significant difference was seen in stride length (d = 0.583, P = 0.016).ConclusionsAn increase in quasi-stiffness when walking across destabilising terrain was attributed to a magnified shock absorption mechanism, facilitating an increased flexion angle during the stance phase. This causes a lower centre of mass resulting in the musculoskeletal system having to produce a greater knee extensor moment to prevent the knee collapsing. Therefore, transfemoral prostheses should be tuned to apply increased extension moments if ambulation is to occur on a destabilising terrain.     

Engagement in linkage to mental health care program in the Rockaways after Hurricane Sandy

The Rockaways area of New York City was especially devastated by Hurricane Sandy. This study examined participant characteristics associated with acceptance of a linkage to and attendance at appointments for mental health difficulties (MHD). Participants (N = 1,011) completed questionnaires to assess mental health symptoms. Participants who met screening criteria (n = 442) were offered linkage to care. Individuals who had a higher mental health symptom burden (MHSB; i.e., those who screened in on more than one criteria vs. only one criterion) had 2.68 greater odds of accepting services (95% confidence interval [1.68, 4.26]). MHSB was not associated with attending a first appointment (p = 0.80). Female gender and Hispanic ethnicity were also associated with acceptance of linkage to care, though not attendance. Reducing stigma around MHD associated with natural disasters and increasing knowledge about the mental health care system could promote help‐seeking behavior among survivors.     

Building skill in heart failure self-care among community dwelling older adults: Results of a pilot study

Objective

Most of the day-to-day care for heart failure (HF) is done by the patient at home and requires skill in self-care. In this randomized controlled trial (RCT) we tested the efficacy of a community-based skill-building intervention on HF self-care, knowledge and health-related quality of life (HRQL) at 1- and 3-months.

Methods

An ethnically diverse sample (n = 75) of patients with HF (53% female; 32% Hispanic, 27% Black; mean age 69.9 ± 10 years) was randomized to the intervention group (IG) or a wait-list control group (CG). The protocol intervention focused on tactical and situational HF self-care skill development delivered by lay health educators in community senior centers. Data were analyzed using mixed (between–within subjects) ANOVA.

Results

There was a significant improvement in self-care maintenance [F(2, 47) = 3.42, p = .04, (Cohen's f = .38)], self-care management [F(2, 41) = 4.10, p = .02, (Cohen's f = .45) and HF knowledge [F(2, 53) = 8.00, p = .001 (Cohen's f = .54)] in the IG compared to the CG.

Conclusions

The skill-building intervention improved self-care and knowledge but not HRQL in this community-dwelling sample.

Practice implications

Delivering an intervention in a community setting using lay health educators provides an alternative to clinic- or home-based teaching that may be useful across diverse populations and geographically varied settings.     

Sleep‐related attentional bias in poor versus good sleepers is independent of affective valence

Contradictory evidence exists relating to the presence of an attention bias to sleep‐related stimuli in poor sleepers/insomnia using the emotional Stroop task (EST). These inconsistencies may be due to methodological issues related to the affective valence of the sleep‐related stimuli. Thus, individuals may attend differentially to sleep‐related stimuli not because of their ‘sleep’ properties, but their negativity. The current study addresses this by controlling the affective valence of sleep‐related words. A total of 107 participants [mean age = 33.22 years, standard deviation (SD) = 12.31 years; 61.7% female] were recruited during an evening event at the Newcastle Science Festival. Participants completed the Pittsburgh Sleep Quality Index (PSQI) and a computerized EST containing 20 non‐affective sleep‐related, 20 neutral and 20 negatively valenced threat words. Good and poor sleepers were categorized using the PSQI. There were no significant differences between groups on response latency to sleep‐related words (t₍₁₀₅₎ = –0.30, P = 0.76). However, the interaction between good versus poor sleepers and word‐type on response latency was significant (F_(2,210) = 3.06, P < 0.05). Poor sleepers took longer to respond to sleep‐related words (mean = 723.35, SD = 172.55) compared to threat words (mean = 694.63, SD = 162.17) than good sleepers (mean = 713.20, SD = 166.32; and mean = 716.65, SD = 181.14). The results demonstrate the presence of an attention bias towards sleep‐related stimuli compared to threat stimuli in poor sleepers. Accordingly, poor sleepers may be consumed by stimuli relevant to their specific difficulties, as well as being more highly attuned to negative cues that signal anxious states. Thus, the present research suggests that there are two opposing forces at play: one which facilitates performance (non‐specific threats) and one which hinders performance (personally relevant threats).     

Preschool children's response to behavioural parent training and parental predictors of outcome in routine clinical care

Objective

To investigate the effectiveness of behavioral parent training (BPT) for preschool children with disruptive behaviours and to explore parental predictors of response.

Methods

Parents of 68 preschool children, aged between 2.7 and 5.9 years, participated in BPT. We evaluated the changes in children's behaviour after BPT with a one group pretest–posttest design, using a waiting period for a double pretest. Outcome was based on parents' reports of the intensity and number of behaviour problems on the Eyberg Child Behavior Inventory. Predictor variables included parents' attention‐deficit/hyperactivity disorder symptoms, antisocial behaviours, and alcohol use, and maternal parenting self‐efficacy and disciplining.

Results

Mother‐reported child behaviour problems did not change in the waiting period but improved significantly after BPT (d = 0.63). High levels of alcohol use by fathers and low levels of maternal ineffective disciplining were each associated with somewhat worse outcome.

Conclusions

BPT under routine care conditions clearly improves disruptive behaviours in preschool children. Mothers who consider themselves as inadequate in disciplining and mothers whose partners do not consume high levels of alcohol report the largest improvements.     

Cortical auditory evoked potentials in mild cognitive impairment: Evidence from a temporal‐spatial principal component analysis

Mild cognitive impairment (MCI) is considered an intermediate transitional stage for the development of dementia, especially Alzheimer's disease. The identification of neurophysiological biomarkers for MCI will allow improvement in detecting and tracking the progression of cognitive impairment. The primary objective of this study was to compare cortical auditory evoked potentials between older adults with and without probable MCI to identify potential neurophysiological indicators of cognitive impairment. We applied a temporal‐spatial principal component analysis to the evoked potentials achieved during the processing of pure tones and speech sounds, to facilitate the separation of the components of the P1‐N1‐P2 complex. The probable MCI group showed a significant amplitude increase in a factor modeling N1b for speech sounds (Cohen's d = .84) and a decrease in a factor around the P2 time interval, especially for pure tones (Cohen's d = 1.17). Moreover, both factors showed a fair discrimination value between groups (area under the curve [AUC] = .698 for N1b in speech condition; AUC = .746 for P2 in tone condition), with high sensitivity to detect MCI cases (86% and 91%, respectively). The results for N1b suggest that MCI participants may suffer from a deficit to inhibit irrelevant speech information, and the decrease of P2 amplitude could be a signal of cholinergic hypoactivation. Therefore, both components could be proposed as early biomarkers of cognitive impairment.
