Interventions for childhood overweight and obesity that target parents as the agents of change by increasing parent self-efficacy for facilitating their child's healthy weight behaviours require a reliable and valid tool to measure parent self-efficacy before and after interventions. Nelson and Davis developed the Parent Efficacy for Child Healthy Weight Behaviour (PECHWB) scale with good preliminary evidence of reliability and validity. The aim of this research was to provide further psychometric evidence from an independent Australian sample.
Data were provided by a convenience sample of 261 primary caregivers of children aged 4-17 years via an online survey. PECHWB scores were correlated with scores on other self-report measures of parenting efficacy and 2- to 4-week test-retest reliability of the PECHWB was assessed.
The results of the study confirmed the four-factor structure of the PECHWB (Fat and Sugar, Sedentary Behaviours, Physical Activity, and Fruit and Vegetables) and provided strong evidence of internal consistency and test-retest reliability, as well as good evidence of convergent validity.
Future research should investigate the properties of the PECHWB in a sample of parents of overweight or obese children, including measures of child weight and actual child healthy weight behaviours to provide evidence of the concurrent and predictive validity of PECHWB scores.
针对儿童超重和肥胖的干预措施，将父母作为改变的推动者，通过提高父母促进孩子健康体重行为的自我效能，这需要一个可靠且有效的工具来测量干预前后父母的自我效能。纳尔逊和戴维斯开发了儿童健康体重行为父母效能（PECHWB）量表，初步显示出良好的信效度证据。本研究的目的是从澳大利亚的一个独立样本中提供进一步的心理测量学证据。
通过在线调查，从261名4至17岁儿童的主要照顾者的便利样本中获取数据。将PECHWB得分与其他育儿效能自我报告测量的得分进行相关性分析，并评估PECHWB两周至四周的重测信度。
研究结果证实了PECHWB的四因素结构（脂肪和糖、久坐行为、体育活动以及水果和蔬菜），并提供了内部一致性和重测信度的有力证据，以及良好的收敛效度证据。
未来的研究应在超重或肥胖儿童的父母样本中调查PECHWB的特性，包括儿童体重测量和儿童实际健康体重行为，以提供PECHWB得分的同时效度和预测效度的证据。
