This study examined the psychometric properties of the Substance Abuse Subtle Screening Inventory (SASSI-2) with college students.
The first part of the study examined the test-retest reliability of the SASSI-2 at 2-week (n = 55) and 4-week (n = 47) intervals with students recruited from introductory psychology courses. The second part used a new sample of 164 college students to assess the internal consistency of the SASSI-2 subscales, the relationship of the SASSI-2 with other common alcohol screening instruments, and its reactivity to response biases. Participants completed the SASSI-2 under standard instructions, or instructions to minimize any alcohol problems they might have (fake good), or to exaggerate any alcohol problems they might have (fake bad). They then completed the CAGE, MAC and MAST under those measures' standard instructions.
The 2-week and 4-week test-retest reliability of the SASSI-2 subscales was moderate to high, but the test-retest reliability for overall classification as "chemically dependent" or "non-chemically dependent" was moderate at 2 weeks and relatively poor at 4 weeks. Internal consistencies for the SASSI-2 subscales ranged from poor to strong (Cronbach alphas ranging from .11 to .93), and the SASSI-2 drinker classification status correlated moderately with drinker classifications based on the CAGE, MAC and MAST. There was no difference in the proportion of participants classified as "chemically dependent" on the SASSI-2 when instructed to "fake good" and under standard instructions, but college students scored as "chemically dependent" more frequently when instructed to "fake bad."
When the SASSI-2 is used with college students, its reliability and validity are comparable to other instruments that currently exist in the public domain. The vulnerability of the SASSI-2 to intentional faking warrants further investigation.
本研究检验了药物滥用细微筛查量表(SASSI - 2)在大学生中的心理测量特性。
研究的第一部分,对从心理学入门课程招募的学生,在间隔2周(n = 55)和4周(n = 47)时检验SASSI - 2的重测信度。第二部分使用164名大学生的新样本,评估SASSI - 2分量表的内部一致性、SASSI - 2与其他常见酒精筛查工具的关系及其对反应偏差的反应性。参与者按照标准指导语完成SASSI - 2,或按照尽量减少其可能存在的任何酒精问题的指导语(假装良好),或按照夸大其可能存在的任何酒精问题的指导语(假装不良)。然后他们在这些测量工具的标准指导语下完成CAGE、MAC和MAST。
SASSI - 2分量表的2周和4周重测信度为中度到高度,但总体分类为“化学依赖”或“非化学依赖”的重测信度在2周时为中度,在4周时相对较差。SASSI - 2分量表的内部一致性从差到强不等(克朗巴哈系数范围从0.11到0.93),SASSI - 2饮酒者分类状态与基于CAGE、MAC和MAST的饮酒者分类中度相关。在“假装良好”指导语下和标准指导语下,被SASSI - 2分类为“化学依赖”的参与者比例没有差异,但在“假装不良”指导语下,大学生更频繁地被评为“化学依赖”。
当SASSI - 2用于大学生时,其信度和效度与目前公共领域中存在的其他工具相当。SASSI - 2易受故意伪装影响这一问题值得进一步研究。
