Abstract

PRIMARY OBJECTIVE

To investigate the internal consistency, long-term stability and validity of the Life Satisfaction Index-A (LSI-A) in a sample of survivors of traumatic brain injury (TBI).

RESEARCH DESIGN

Cohort study.

METHODS AND PROCEDURES

LSI-A was administered to survivors of TBI at 12, 24, 48 and 60 months post-injury during telephone interviews. Participants rated their quality of life, independence and participation in activities as well as health status at 24 months. Internal consistency was evaluated with Coefficient alpha. Pearson's r was used to investigate score stability. Test validity was explored with Pearson's r and Analysis of Covariance with age and sex as covariates.

EXPERIMENTAL INTERVENTIONS

None.

MAIN OUTCOMES AND RESULTS

Coefficient alphas ranged from 0.85-0.92. Test-re-test coefficients ranged from 0.42-0.77. The LSI-A was positively correlated with self-reported quality of life, independence, activity level and health status.

CONCLUSIONS

The LSI-A is a reliable and valid measure of the construct of life satisfaction among survivors of TBI.

摘要

主要目标

在创伤性脑损伤（TBI）幸存者样本中，研究生活满意度指数-A（LSI-A）的内部一致性、长期稳定性和有效性。

研究设计

队列研究。

方法与步骤

在受伤后12个月、24个月、48个月和60个月通过电话访谈对TBI幸存者进行LSI-A测评。参与者在24个月时对其生活质量、独立性、活动参与度以及健康状况进行评分。使用α系数评估内部一致性。采用Pearson相关系数r研究分数稳定性。以年龄和性别作为协变量，通过Pearson相关系数r和协方差分析探讨测试效度。
