Evidence suggests that indoor tanning may have addictive properties. However, many instruments for measuring indoor tanning addiction show poor validity and reliability. Recently, a new instrument, the Behavioral Addiction Indoor Tanning Screener (BAITS), has been developed.
To test the validity and reliability of the BAITS by using a multimethod approach.
We used data from the first wave of the National Cancer Aid Monitoring on Sunbed Use, which included a cognitive pretest (August 2015) and a Germany-wide representative survey (October to December 2015). In the cognitive pretest 10 users of tanning beds were interviewed and 3000 individuals aged 14-45 years were included in the representative survey. Potential symptoms of indoor tanning addiction were measured using the BAITS, a brief screening survey with seven items (answer categories: yes vs. no). Criterion validity was assessed by comparing the results of BAITS with usage parameters. Additionally, we tested internal consistency and construct validity.
A total of 19·7% of current and 1·8% of former indoor tanning users were screened positive for symptoms of a potential indoor tanning addiction. We found significant associations between usage parameters and the BAITS (criterion validity). Internal consistency (reliability) was good (Kuder-Richardson-20, 0·854). The BAITS was shown to be a homogeneous construct (construct validity).
Compared with other short instruments measuring symptoms of a potential indoor tanning addiction, the BAITS seems to be a valid and reliable tool. With its short length and the binary items the BAITS is easy to use in large surveys.
有证据表明，室内晒黑可能具有成瘾性。然而，许多用于测量室内晒黑成瘾的工具都显示出较差的有效性和可靠性。最近，一种新的工具，即行为成瘾室内晒黑筛查器（BAITS）已经被开发出来。
采用多方法的方法来测试 BAITS 的有效性和可靠性。
我们使用了国家癌症援助监测日光浴使用的第一波数据，其中包括认知预测试（2015 年 8 月）和德国全国代表性调查（2015 年 10 月至 12 月）。在认知预测试中，对 10 名日光浴床使用者进行了访谈，在代表性调查中纳入了 3000 名 14-45 岁的个体。使用 BAITS 测量室内晒黑成瘾的潜在症状，BAITS 是一个有七个项目的简短筛查调查（答案类别：是/否）。通过将 BAITS 的结果与使用参数进行比较来评估标准有效性。此外，我们还测试了内部一致性和结构有效性。
共有 19.7%的当前和 1.8%的以前的室内晒黑使用者被筛查出有潜在的室内晒黑成瘾症状。我们发现使用参数与 BAITS 之间存在显著关联（标准有效性）。内部一致性（可靠性）良好（Kuder-Richardson-20，0.854）。BAITS 被证明是一个同质的结构（结构有效性）。
与其他用于测量潜在室内晒黑成瘾症状的简短工具相比，BAITS 似乎是一种有效且可靠的工具。BAITS 长度较短，项目为二进制，因此在大型调查中使用方便。
