The purpose of this paper was to assess the psychometric properties of the Students' Life Satisfaction Scale (SLSS) and the Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS) when used with youth who have chronic conditions. Baseline data from a longitudinal study examining predictors of changes in perceived quality of life (PQOL) for youth with chronic conditions were used. SLSS and BMSLSS data were collected on over 400 youth aged 11-17 using youth self-report and parent proxy-report versions. Internal consistency, convergent validity, and factor structure were examined for both versions. Extent of agreement and magnitude of differences between youth and parent report were evaluated. Finally, gender, age, and condition group differences in youth report scores were examined for the SLSS and BMSLSS. Strong internal consistency was demonstrated for the youth and parent reports of both measures. As with normative samples, a single factor structure was found for youth and parent reports of the BMSLSS. However, both youth and parent reports of the SLSS had a two-factor structure: one consisting of five positively worded items, and the other, two negatively worded items. Youth reported their PQOL to be significantly higher than did their parents. Significant differences in PQOL scores for the youth report were not found by age, gender, or conditions. Findings show that, from a psychometric standpoint, the BMSLSS (both youth and parent report) is a promising measure of PQOL for use in population-based research with youth who have chronic conditions. The SLSS may need to be revised to exclude negative items when used with this population of youth.
本文的目的是评估学生生活满意度量表（SLSS）和简短多维学生生活满意度量表（BMSLSS）在用于患有慢性病的青少年时的心理测量特性。研究使用了一项纵向研究的基线数据，该研究考察了慢性病青少年感知生活质量（PQOL）变化的预测因素。通过青少年自评和家长代理报告版本，收集了400多名11至17岁青少年的SLSS和BMSLSS数据。对两个版本都进行了内部一致性、收敛效度和因子结构的检验。评估了青少年报告与家长报告之间的一致程度和差异大小。最后，考察了SLSS和BMSLSS在青少年报告分数上的性别、年龄和疾病组差异。两种测量方法的青少年报告和家长报告都显示出很强的内部一致性。与常模样本一样，BMSLSS的青少年报告和家长报告都发现了单一因子结构。然而，SLSS的青少年报告和家长报告都有一个双因子结构：一个由五个正向措辞的项目组成，另一个由两个负向措辞的项目组成。青少年报告的PQOL显著高于他们的父母。在青少年报告中，未发现PQOL分数在年龄、性别或疾病方面存在显著差异。研究结果表明，从心理测量学角度来看，BMSLSS（青少年报告和家长报告）是一种很有前景的PQOL测量方法，可用于对患有慢性病的青少年进行基于人群的研究。当与这类青少年群体一起使用时，SLSS可能需要进行修订以排除负向项目。
