BACKGROUND
Lifestyle is intimately related to health. A questionnaire that specifically scores the healthiness of lifestyle of Catalan adolescents is needed. The objective of this study was to develop and validate a scoring questionnaire called VISA-TEEN to assess the healthy lifestyle of young Catalans that can be answered quickly and user-friendly.
METHODS
A lifestyle questionnaire was developed based on the analysis of contributions from two focus groups, one with adolescents and the other with people who work with them (teachers and doctors). A panel of experts validated the content of items that were ultimately selected for the VISA-TEEN questionnaire. Three hundred ninety-six adolescents (215 boys and 181 girls, age = 13-19 years) completed the VISA-TEEN. Internal consistency was assessed using Cronbach's alpha (α) reliability coefficient. Test-retest reliability, using an intraclass correlation coefficient (ICC), was calculated based on scores attained two weeks apart. Construct validity was assessed by the extraction of components with an exploratory factor analysis. The relationship between the scores was measured using the health-related quality of life (HRQoL) KIDSCREEN-10 Index (the relationship was assessed by calculating Pearson's r correlation coefficient). The association of scores in the VISA-TEEN for self-rated health (SRH) was also examined by executing an analysis of variance (ANOVA) between the different categories of this variable. We also calculated the index of fit for factor scales (IFFS) for each component, as well as the discriminatory power of the instrument using Ferguson's δ (delta) coefficient.
RESULTS
The VISA-TEEN questionnaire showed acceptable reliability (α = 0.66, αest = 0.77) and a very good test-retest agreement (ICC = 0.860). It could be broken down into the following five components, all with an acceptable or very good IFFS (0.7-0.96): diet, substance abuse, physical activity, Rational Use of Technological Leisure (RUTL), and hygiene. Scores on the VISA-TEEN showed significant correlation with the KIDSCREEN index (r = 0.21, p < 0.001) and were associated with SRH (p < 0.001). The discriminatory power was found to be δ = 0.97.
CONCLUSIONS
The VISA-TEEN questionnaire developed to study the lifestyle of Catalan adolescents is a valid instrument to apply in this population as it is shown in the present psychometric tests to understand the role of lifestyle in the health of teenagers or to test the efficacy of health campaigns intended to improve teenagers' lifestyle.
背景
生活方式与健康密切相关。需要一份专门对加泰罗尼亚青少年生活方式的健康程度进行评分的问卷。本研究的目的是开发并验证一份名为VISA - TEEN的评分问卷，以评估加泰罗尼亚年轻人的健康生活方式，该问卷应具备回答迅速且用户友好的特点。
方法
基于对两个焦点小组意见的分析制定了一份生活方式问卷，其中一个焦点小组由青少年组成，另一个由与他们共事的人员（教师和医生）组成。一个专家小组对最终入选VISA - TEEN问卷的项目内容进行了验证。396名青少年（215名男孩和181名女孩，年龄在13 - 19岁之间）完成了VISA - TEEN问卷。使用克朗巴哈α（α）可靠性系数评估内部一致性。基于相隔两周获得的分数，使用组内相关系数（ICC）计算重测信度。通过探索性因素分析提取成分来评估结构效度。使用与健康相关的生活质量（HRQoL）KIDSCREEN - 10指数测量分数之间的关系（通过计算皮尔逊r相关系数来评估这种关系）。还通过对该变量不同类别之间进行方差分析（ANOVA）来检验VISA - TEEN中自我评定健康（SRH）分数的关联。我们还计算了每个成分的因子量表拟合指数（IFFS），以及使用弗格森δ（delta）系数评估该工具的区分能力。
结果
VISA - TEEN问卷显示出可接受的信度（α = 0.66，αest = 0.77）和非常好的重测一致性（ICC = 0.860）。它可以分解为以下五个成分，所有成分的IFFS均可接受或非常好（0.7 - 0.96）：饮食、药物滥用、体育活动、合理使用技术休闲（RUTL）和卫生。VISA - TEEN的分数与KIDSCREEN指数显著相关（r = 0.21，p < 0.001），并且与自我评定健康（SRH）相关（p < 0.001）。发现区分能力为δ = 0.97。
结论
为研究加泰罗尼亚青少年生活方式而开发的VISA - TEEN问卷是一种适用于该人群的有效工具，正如在当前的心理测量测试中所显示的那样，它有助于理解生活方式在青少年健康中的作用，或测试旨在改善青少年生活方式的健康运动的效果。
