本横断面研究的目的是检查两个适应SRQ措施评估青年1型糖尿病的动机内化为健康饮食和他们的父母的动机内化为家庭提供健康膳食的心理测量学特性。外部效度的适应SRQ进行了评估方面的健康饮食态度（健康饮食自我效能、障碍和结果预期）通过问卷、饮食质量评估（健康饮食指数-2005，HEI-2005;营养丰富的食物指数9.3，NRF9.3;全植物食物密度（WPFD）通过3天食物记录评估，BMI通过测量1型糖尿病青年的身高和体重评估（N=136，年龄12.3±2.5岁）及其父母。探索性因素分析与方差最大旋转产生了一个双因素结构与预期的自主和控制的动机因素的青年和父母。分量表的内部方差是可接受的（α=0.66-0.84）。青少年自主和控制动机总体上呈正相关（r=0.30，p<0.001）;然而，在按年龄分层的分析中（<13岁vs. ≥ 13岁），相关性在≥ 13岁的青少年中不显著。自主动机与更高的自我效能（青年：r=0.39，父母：r=0.36），积极的结果预期（青年：r=0.30，父母：r=0.35）以及更少的健康饮食障碍（青年：r=-0.36，父母：r=-0.32）显著相关（p<0.001）。控制性动机与父母的消极结果期望正相关（r=0.29，p<0.01），与青少年的积极（r=0.28，p<0.01）和消极（r=0.34，p<0.001）结果期望均正相关。对于父母（NRF9.3 r=0.22; WPFD r=0.24; HEI-2005 r=0.22）和≥ 13岁的青年（NRF9.3 r=0.26），自主动机与饮食质量指标呈正相关（p<0.05），但与<13岁的青年无关。在父母中，而不是年轻人中，BMI与自主动机呈负相关（r=-0.33，p<0.001），与控制动机呈正相关（r= 0.27，p<0.01）。研究结果提供了初步的支持SRQ在这一人群中，并建议潜在的发展差异的作用，健康饮食的动机在儿童，青少年和成人。
The purpose of this cross-sectional study was to examine the psychometric properties of two adapted SRQ measures assessing youth with type 1 diabetes motivation internalization for healthful eating and their parents motivation internalization for providing healthy meals for the family. External validity of the adapted SRQ was evaluated with respect to healthy eating attitudes (healthful eating self-efficacy, barriers, and outcome expectations) assessed by questionnaire, diet quality (Healthy Eating Index-2005, HEI-2005; Nutrient-Rich Foods Index 9.3, NRF9.3; Whole Plant Food Density, WPFD) assessed by 3-day food records, and BMI assessed by measured height and weight in youth with type 1 diabetes (N=136, age 12.3±2.5 years) and their parents. Exploratory factor analysis with varimax rotation yielded a two-factor structure with the expected autonomous and controlled motivation factors for both youth and parents. Internal consistencies of subscales were acceptable (α=0.66–0.84). Youth autonomous and controlled motivation were positively correlated overall (r=0.30, p<0.001); however, in analyses stratified by age (<13 vs. ≥13y), the correlation was not significant for youth ≥13y. Autonomous motivation was significantly associated (p<0.001) with greater self-efficacy (youth: r=0.39, parent: r=0.36), positive outcome expectations (youth: r=0.30, parent: r=0.35), and fewer barriers to healthful eating (youth: r=−0.36, parent: r=−0.32). Controlled motivation was positively correlated with negative outcome expectations for parents (r=0.29, p<0.01), and both positive (r=0.28, p<0.01) and negative (r=0.34, p<0.001) outcome expectations for youth. Autonomous motivation was positively associated (p<0.05) with diet quality indicators for parents (NRF9.3 r=0.22; WPFD r=0.24; HEI-2005 r=0.22) and youth ≥13y (NRF9.3 r=0.26), but not youth <13y. Among parents, but not youth, BMI was associated negatively with autonomous motivation (r=−.33, p<.001) and positively with controlled motivation (r=.27, p<.01). Findings provide initial support for the SRQ in this population and suggest potential developmental differences in the role of motivation on healthful eating among children, adolescents, and adults.
