The smartphone is an increasingly widespread technological vehicle for general health and psychological health promotion, evaluation, education, and sometimes intervention. However, the psychometric performance of behavioral health screening measures has not been commonly evaluated for the new, small-format, touch-screen medium. Before mobile-based applications for behavioral health screening can be disseminated confidently, the reliability and the validity of measures administered by the smartphone must be evaluated. We compared psychometric properties (i.e., internal consistency and test-retest reliability) of seven behavioral health measures completed on paper, a computer, and an iPhone by 45 army soldiers. The results showed the internal consistencies of the smartphone-delivered measures to be equivalent and very high across all three modalities and the test-retest reliability of the iPhone measures also to be very high. Furthermore, completion of the behavioral screening measures by the iPhone was highly preferred over the other modalities and was reported to be easy and convenient. Our findings help corroborate the use of smartphones and other small mobile devices for behavioral health screening.
智能手机日益成为促进大众健康和心理健康、进行评估、教育乃至有时实施干预的广泛技术工具。然而，行为健康筛查措施在新的小尺寸触摸屏媒介上的心理测量学表现尚未得到普遍评估。在基于手机的行为健康筛查应用能够放心推广之前，必须评估由智能手机实施的测量方法的可靠性和有效性。我们比较了45名陆军士兵在纸质、计算机和iPhone上完成的七项行为健康测量的心理测量特性（即内部一致性和重测信度）。结果显示，在所有三种方式下，通过智能手机实施的测量方法的内部一致性相当且非常高，iPhone测量方法的重测信度也非常高。此外，与其他方式相比，士兵们非常倾向于通过iPhone完成行为筛查测量，并且报告称这样做轻松便捷。我们的研究结果有助于证实使用智能手机和其他小型移动设备进行行为健康筛查的可行性。
