OBJECTIVE
The General Life Functioning Scale (GLF) was developed to provide a complementary alternative to existing measures of impairment. We examined the psychometric properties of the GLF-Parent version (GLF-P), given the known value of informant ratings.
METHODS
The GLF-P was administered to parents of adults with attention-deficit/hyperactivity disorder (ADHD) diagnosed in childhood and a nonADHD comparison group in the Pittsburgh ADHD Longitudinal Study. GLF-P ratings described 334 participants (ADHD = 186; comparison = 148) rated at age 25 (M = 24.80 years, SD = 0.46, range = 24-26) and 401 participants (ADHD = 237; comparison = 164) rated at age 30 (M = 29.30, SD = 0.64, range = 28-33). Exploratory (EFA) and confirmatory (CFA) factor analyses were used.
RESULTS
EFAs suggested and CFAs confirmed a five-factor solution. We found measurement invariance across diagnostic and age groups, satisfactory internal consistency, construct validity, and known-group validity.
CONCLUSION
Psychometric results suggest the GLF-P as a helpful adjunctive measure of functioning. Further research is needed to determine the utility of the GLF across diverse settings.
目的
一般生活功能量表（GLF）旨在提供一种对现有损伤测量的补充替代方法。鉴于信息提供者评分的已知价值，我们考察了 GLF-家长版（GLF-P）的心理测量学特性。
方法
GLF-P 被用于匹兹堡 ADHD 纵向研究中患有儿童期诊断的注意力缺陷/多动障碍（ADHD）的成年患者的家长和非 ADHD 对照组。GLF-P 评定了 334 名参与者（ADHD=186；对照组=148）在 25 岁时（M=24.80 岁，SD=0.46，范围=24-26），401 名参与者（ADHD=237；对照组=164）在 30 岁时（M=29.30，SD=0.64，范围=28-33）的情况。我们使用了探索性（EFA）和验证性（CFA）因子分析。
结果
EFA 提出并 CFA 证实了五因素解决方案。我们发现，诊断和年龄组之间存在测量不变性，具有令人满意的内部一致性、结构有效性和已知组有效性。
结论
心理测量学结果表明 GLF-P 是一种有用的功能辅助测量工具。需要进一步研究以确定 GLF 在不同环境中的效用。
