Replicability of sight word training and phonics training in poor readers: a randomised controlled trial.

ABSTRACT: Given the importance of effective treatments for children with reading impairment, paired with growing concern about the lack of scientific replication in psychological science, the aim of this study was to replicate a quasi-randomised trial of sight word and phonics training using a randomised controlled trial (RCT) design. One group of poor readers (N = 41) did 8 weeks of phonics training (i.e., phonological decoding) and then 8 weeks of sight word training (i.e., whole-word recognition). A second group did the reverse order of training. Sight word and phonics training each had a large and significant valid treatment effect on trained irregular words and word reading fluency. In addition, combined sight word and phonics training had a moderate and significant valid treatment effect on nonword reading accuracy and fluency. These findings demonstrate the reliability of both phonics and sight word training in treating poor readers in an era where the importance of scientific reliability is under close scrutiny.

Project description:BackgroundAlthough medical interventions play an important role in preserving lives and maternal comfort they have become increasingly routine in normal childbirth. This may increase the risk of associated complications and a less satisfactory birth experience. Antenatal hypnosis is associated with a reduced need for pharmacological interventions during childbirth. This trial seeks to determine the efficacy or otherwise of antenatal group hypnosis preparation for childbirth in late pregnancy.Methods/designA single centre, randomised controlled trial using a 3 arm parallel group design in the largest tertiary maternity unit in South Australia. Group 1 participants receive antenatal hypnosis training in preparation for childbirth administered by a qualified hypnotherapist with the use of an audio compact disc on hypnosis for re-enforcement; Group 2 consists of antenatal hypnosis training in preparation for childbirth using an audio compact disc on hypnosis administered by a nurse with no training in hypnotherapy; Group 3 participants continue with their usual preparation for childbirth with no additional intervention. Women > 34 and < 39 weeks gestation, planning a vaginal birth, not in active labour, with a singleton, viable fetus of vertex presentation, are eligible to participate. Allocation concealment is achieved using telephone randomisation. Participants assigned to hypnosis groups commence hypnosis training as near as possible to 37 weeks gestation. Treatment allocations are concealed from treating obstetricians, anaesthetists, midwives and those personnel collecting and analysing data. Our sample size of 135 women/group gives the study 80% power to detect a clinically relevant fall of 20% in the number of women requiring pharmacological analgesia - the primary endpoint. We estimate that approximately 5-10% of women will deliver prior to receiving their allocated intervention. We plan to recruit 150 women/group and perform sequential interim analyses when 150 and 300 participants have been recruited. All participant data will be analysed, by a researcher blinded to treatment allocation, according to the "Intention to treat" principle with comprehensive pre-planned cost- benefit and subgroup analyses.DiscussionIf effective, hypnosis would be a simple, inexpensive way to improve the childbirth experience, reduce complications associated with pharmacological interventions, yield cost savings in maternity care, and this trial will provide evidence to guide clinical practice.

Project description:ObjectivesTo investigate how different competing interest (COI) statements affect clinical readers' perceptions of education articles.DesignRandomised controlled trial.Setting and participantsRandom sample of UK doctors.InterventionsWe created four permutations of each of two clinical reviews (on gout or dyspepsia), which varied only in terms of the COI statement. Volunteers were blinded and randomised to receive one review and asked to complete a questionnaire after reading it. Blinded factorial analyses of variance and analyses of covariance were carried out to assess the influence of each review and type of COI on outcomes.Primary and secondary outcomesConfidence in the article's conclusions (primary outcome), its importance, their level of interest in the article and their likelihood to change practice after reading it.ResultsOf 10 889 doctors invited to participate, 1065 (10%) volunteered. Of these, 749 (70%) completed the survey. Analysis of covariance (adjusting for age, sex, job type, years since qualification) showed no significant difference between the groups in participants' confidence in the article (gout: p=0.32, dyspepsia: p=0.78) or their rating of its importance (gout: p=0.09, dyspepsia: p=0.79). For the gout review, participants rated articles with advisory board and consultancies COI as significantly less interesting than those with no COI (p=0.028 with Bonferroni correction). Among participants indicating that they treat the condition and that the article's recommendations differed from their own practice, there was no significant difference in likelihood to change practice between groups (gout: p=0.59, n=59; dyspepsia: p=0.56, n=80).ConclusionsDoctors' confidence in educational articles was not influenced by the COI statements. Further work is required to determine if doctors do not perceive these COIs as important in educational articles or if they do not pay attention to these statements. More meaningful COI disclosure practices may be needed, which highlight context-specific potential sources of bias to readers.Trial registration numberNCT02548312; Results.
