Background
The current food pyramid guidelines have been criticized because of their complexity and the knowledge required for users to understand the recommendations. Simplification of a dietary message to focus on a single key aspect of dietary quality, e.g., fiber intake, may make the message much easier to comprehend and adhere, such that respondents can achieve greater weight loss, better dietary quality and overall metabolic health. 相似文献3.

Objectives
There is limited information on how a change in patients' expectations over time results in symptom change in psychotherapy. This study aimed to investigate the changes in patients' expectations and symptoms during treatment and across follow-up as well as to determine the within- and between-patient relationships between two types of patient expectations, that is, self-efficacy and outcome expectation, and symptom change.Methods
Participants (80 participants × 6 repeated measures; 480 observations) with generalized anxiety disorder were treated using cognitive behavioral therapy and the within- and between-patient scores of self-efficacy and outcome expectation were evaluated in multilevel models as predictors of symptom change.Results
Patients' self-efficacy and outcome expectation increased, whereas severity of their symptoms reduced during and after treatment. At the within-patient (WP) level, an increase in self-efficacy was associated with a decrease in worry and depressive symptoms, and an increase in outcome expectation was associated with a decrease in depressive symptoms. The between-patient (BP) effect, however, was contrary to the WP effect, that is, self-efficacy was positively correlated with worry and outcome expectation was positively correlated with depressive symptomsConclusion
These results highlight the importance of disaggregating the WP variability from BP variability in psychotherapy process–outcome research as they exhibit different associations at the within- and between-patient levels. Clinical Trial Registration: ClinicalTrial.gov (NCT03079336). 相似文献5.

Background
Herbs and other dietary supplements are among the most commonly used complementary medical therapies. However, clinicians generally have limited knowledge, confidence and communication about herbs and dietary supplements (HDS). We compared diverse clinicians' expertise about HDS to better target future curricula. 相似文献6.

Background
Changes of health and quality-of-life in chronic conditions are mostly small and require specific and sensitive instruments. The aim of this study was to determine and compare responsiveness, i.e. the sensitivity to change of five outcome instruments for effect measurement in chronic pain. 相似文献7.

Background
The "real" effect size of a medical therapy is constant over time. In contrast, the effect size reported in randomised controlled trials (RCTs) may change over time because the sum of all kinds of bias influencing the reported effectiveness is not necessarily constant. As this would affect the validity of meta-analyses, we tested the hypothesis that the reported effect size decreases over time. Furthermore, we tested three hypotheses that would explain a possible change. 相似文献9.

Background
The extent to which a health care intervention causes or facilitates health-related change is a key question in research. The need to quantify such change has led to the development of an increasing number of change indicators, to measure what have come to be known as 'outcomes'. In the context of medical research into the efficacy or effectiveness of an intervention the term 'outcomes' has often been interpreted to mean single endpoints with a linear cause and effect link to an external intervention. 相似文献10.
Background
Many health professionals lack the skills to find and appraise published research. This lack of skills and associated knowledge needs to be addressed, and practice habits need to change, for evidence-based practice to occur. The aim of this before and after study was to evaluate the effect of a multifaceted intervention on the knowledge, skills, attitudes and behaviour of allied health professionals. 相似文献11.
Background
Changing clinicians' behaviour is recognised as a major challenge. It is clear that behaviour change not only depends on demonstrating the proven effectiveness of clinical interventions; contextual and occupational factors, such as 'change readiness', may be central to their implementation. This paper highlights the context of behaviour change in relation to a healthcare innovation introduced within primary care, highlighting the importance of organisational and interpersonal factors that may help explain the dynamics of implementation. 相似文献12.

Background
It is important to demonstrate learning outcomes of simulation in technology based practices, such as in advanced health care. Although many studies show skills improvement and self-reported change to practice, there are few studies demonstrating patient outcome and societal efficiency. 相似文献13.
Background
Previous research has shown that internet education can lead to short-term improvements in clinicians' knowledge, confidence and communication practices. We wished to better understand the duration of these improvements and whether different curriculum delivery strategies differed in affecting these improvements. 相似文献14.

Background
Reporting numbers needed to treat (NNT) improves interpretability of trial results. It is unusual that continuous outcomes are converted to numbers of individual responders to treatment (i.e., those who reach a particular threshold of change); and deteriorations prevented are only rarely considered. We consider how numbers needed to treat can be derived from continuous outcomes; illustrated with a worked example showing the methods and challenges. 相似文献15.

Purpose
Temporal self-regulation theory was developed to address an observed intention-behaviour gap across behaviours. However, a synthesis of studies has not yet been conducted to investigate the theory's utility to explain behaviour and bridge the intention-behaviour gap. This review aimed to evaluate the predictive ability of temporal self-regulation theory to understanding behaviour and pre-registered at PROSPERO (ID: CRD42021253174).Method
Forward citation searches on the original theory publication through Google Scholar until May 2021 identified 37 eligible articles, including, 12,555 participants assessing at least two of the three theory constructs. Random-effects meta-analyses assessed the strength of associations between theory constructs on behaviour and random effects meta-regressions assessed moderators of behaviour.Results
Findings provide support for temporal self-regulation theory to explain behaviour with very weak (self-regulatory capacity r = .039, CI = .00, –.07) to moderate (intention r = .331, CI = .26, .40; behavioural pre-potency r = .379, CI = .32, .44) effect sizes. Further, the strength of associations varied across behaviour types and contexts. However, there was high heterogeneity across studies and some moderating effects could not be assessed due to insufficient numbers of studies assessing interactions.Conclusions
We urge researchers to assess and report interactions for better understanding of the drivers of behaviour to develop effective interventions for positive behaviour change. 相似文献17.

Objectives
There are two alternative hypotheses regarding bidirectional associations between self-efficacy and planning in predicting health behaviour change: self-efficacy may establish planning (cultivation hypothesis) or planning may enable the formation of self-efficacy (enabling hypothesis). This study investigates the order in which these two social cognitions are linked in adult–adult dyads in the context of sedentary behaviours (SB).Design
A longitudinal study with 4 measurement points, spanning 8 months.Methods
A total of 320 dyads (age: 18–90 years) were enrolled. Dyads included a focus person (who received the recommendation to reduce SB and intended to change their SB), and their partners, who were willing to support the focus persons and intended to reduce their own SB as well. Data were collected at Time 1 (T1), Time 2 (1 week later, T2), Time 3 (T3, 2 months after T1) and Time 4 (T4, 8 months after T1). SB was measured with accelerometers at (T1 and T4). Mediation models with individual and dyadic reciprocal effects were tested with path analyses.Results
Only one indirect effect was found: A higher level of partners' SB reduction-specific self-efficacy at T2 was related to the focus person's more frequent planning to reduce SB at T3, which, in turn, predicted lower SB time among partners at T4.Conclusions
The findings provide partial support for the cultivation model (self-efficacy prompting planning) and for dyadic reciprocal associations in the context of SB time reduction among adult dyads. 相似文献18.

Objectives
Interventions promoting habitual fruit consumption have the potential to bring about long-term behaviour change. Assessing the effectiveness of such interventions requires adequate habit and behaviour measures. Habits are based on learned context-behaviour associations, so measures that incorporate context should be more sensitive to expected habit and behaviour changes than context-free measures. This study compared context-specific and context-free measures of fruit consumption habit and behaviour following a 3-week habit formation intervention.Design
Prospective online study (n = 58).Methods
Behaviour frequency was assessed across five timepoints, retrospectively (Time 1 [T1], T5) or via daily diary data (uploaded weekly at T2, T3 and T4). Habit strength was assessed before (T1) and immediately after the intervention (T4), and again 2 weeks later (T5). Analyses of variance were run, with time and context specificity as within-subject factors, and habit and behaviour frequency as dependent measures.Results
An interaction between time and context specificity was found in both analyses (habit: F(2,114) = 12.848, p < .001, part.η2 = .184; behaviour: F(2,114) = 6.714, p = .002, part.η2 = .105). Expected habit formation patterns 5 weeks post-baseline were only detected by the context-specific habit measure. Likewise, increased behaviour frequency was only found when the target context was specified (p's < .001).Conclusions
Assessments of purposeful dietary habit and behaviour change attempts should incorporate context-specific measurement. 相似文献20.
