For the final measure: the Chi-Square goodness of fit statistic was 3447.19; the Standardized Root Mean Square Residual (SRMR) was 0.070; the Root Mean Square Error of Approximation (RMSEA) was 0.072; and the Comparative Fit Index (CFI) had a value of 0.78.While only one of the three indices support goodness of fit of the measurement model tested, a 14-domain model with 61 items showed good discriminant validity and internally consistent items.Future research should aim to assess the psychometric properties of the developed TDFQ in other community-based settings. Improving diet in children provides a critical opportunity to improve dietary behaviours in the overall population.Childcare is a particularly opportunistic setting in which to intervene to improve child dietary intake as it provides access to a large proportion of children at a key developmental period of their lives.These studies collectively conclude that methodological improvements are required to enhance the utility of the existing measures including ensuring that at least three items are available per construct and adding additional contextually relevant items applicable to the specific study setting and target audience.Given the existing gaps in the literature regarding how to best support the implementation of dietary guidelines in the childcare setting, the importance of context in assessing determinants of implementation and the absence of validated tools which can be applied to professional practice regarding nutrition in the childcare setting this study aims to: A cross-sectional survey was undertaken in centre based childcare services (specifically long day care services (LDCs)) in NSW, Australia.Description: The present study further established the construct validity of the Academic Self-regulated Learning Scale (A-SRL-S, Magno, 2010) through its functional correlation with the Motivated Strategies ...

The use of implementation theories or frameworks can be helpful in assessing the determinants of childcare provider behavior to ensure a broad range of factors that may impede or promote implementation are considered.Furthermore implementation frameworks can inform the selection of strategies to support implementation [] few have comprehensive psychometrically evaluated measures to assess their constructs, limiting their utility.One framework for which measures have been psychometrically evaluated is the Theoretical Domains Framework (TDF).The initial version of the framework described 12 domains; however further construct validation research led to a 14 domain framework that is suggested to more comprehensively describe relevant behavior change constructs [].

There have been three previous studies that have empirically validated TDF constructs measures.Of these, 342 (34%) LDC services met the eligibility criteria.LDC services were eligible to participate if the service: located within NSW Australia, was open for greater than 8 h per day; provided two mid-meals and one main-meal to children while in care; planned their menus onsite; prepared all their food onsite; and employed a service cook.Similarly, in 2012, 46 menus from centre based childcare services in the Hunter New England region of New South Wales (NSW) Australia were audited and the study concluded that none complied with the menu dietary guidelines [].
