Abstract

Aim

In response to the growing popularity of mobile devices among older adults in Japan, this study aimed to establish a reliable and valid measure of mobile device proficiency by developing a Japanese version of the Mobile Device Proficiency Questionnaire (MDPQ-J) for the Japanese population.

Methods

To evaluate the reliability and validity of the MDPQ-J, we administered the questionnaire to 100 young or middle-aged participants (37.78 ± 13.90 years, 57.00% women), and 62 older participants (75.90 ± 6.01 years; 59.68% women).

Results

The MDPQ-J showed a high degree of internal consistency (Cronbach's α = 0.98). Moreover, MDPQ-J scores in older participants tended to be lower than those in young or middle-aged participants. In terms of validity, the MDPQ-J score of older participants was significantly associated with age (ρ = −0.31), the amount of time using a mobile device per day (ρ = 0.64), and the system usability scale (ρ = 0.39). Additionally, the MDPQ-J scores were significantly positively associated with the importance (ρ = 0.37), performance (ρ = 0.57), and satisfaction (ρ = 0.29) associated with daily mobile device use in older participants.

Conclusions

The high reliability and validity of the MDPQ-J in the Japanese population highlight its utility in adapting mobile devices for older adults, which is crucial in an increasingly digital society. Further research should explore the mediating role of mobile device proficiency in various health-related outcomes. Geriatr Gerontol Int 2024; 24: 1223–1232.

移动设备能力问卷日语版的开发：横断面验证研究

目的：随着移动设备在日本老年人中的日益普及，本研究旨在通过开发适合日本人群的日语版移动设备熟练程度问卷（MDPQ-J），建立一种可靠有效的移动设备熟练程度测量方法：为了评估 MDPQ-J 的可靠性和有效性，我们对 100 名中青年参与者（37.78 ± 13.90 岁，57.00% 为女性）和 62 名老年参与者（75.90 ± 6.01 岁，59.68% 为女性）进行了问卷调查：MDPQ-J显示出高度的内部一致性（Cronbach's α = 0.98）。此外，老年参与者的 MDPQ-J 分数往往低于中青年参与者。在效度方面，老年参与者的 MDPQ-J 分数与年龄（ρ = -0.31）、每天使用移动设备的时间（ρ = 0.64）和系统可用性量表（ρ = 0.39）显著相关。此外，MDPQ-J得分与老年参与者日常使用移动设备的重要性（ρ = 0.37）、性能（ρ = 0.57）和满意度（ρ = 0.29）呈显著正相关：MDPQ-J在日本人群中的高可靠性和有效性突显了它在为老年人调整移动设备方面的实用性，这在日益数字化的社会中至关重要。进一步的研究应探讨移动设备熟练程度在各种健康相关结果中的中介作用。Geriatr Gerontol Int 2024; --：-----.
