リハビリテーション専門職を対象にした3Dプリント技術学習プログラムの有用性—混合研究法を用いた検討

The usefulness of a 3D printing technology learning program for rehabilitation professionals: A mixed methods study

要旨：リハビリテーション（以下，リハ）専門職10名を対象に体験，振り返り，概念化，積極的施行，報告会を含む3Dプリント技術学習プログラムを実施し，有用性を検討した．実施前，終了後，1ヵ月後の3時点において日本語版修正Technology Acceptance Model質問票を実施した．また，6名に対して，フォーカス・グループ・インタビューを実施した．結果，プログラム後に3Dプリント技術に対する使いやすさの認識が向上し，1ヵ月後も維持していた．質的分析では，参加者の問題解決能力の広がりが確認できた．学習プログラムがリハ専門職の新規技術に対する心理的懸念を軽減し，臨床実践能力を高めることが示唆された．

　The aim of this study was to assess the usefulness of a 3D printing technology learning program. The program which includes concrete experience, reflection, conceptualization, active implementation, and debriefing was conducted on 10 rehabilitation professionals. In order to collect quantitative data, the Japanese version of the modified Technology Acceptance Model questionnaire was conducted three times: before the program, after the program, and one month later. Qualitative data were collected through focus group interviews of six participants. The results indicate that the participants improved their perception of ease of use in 3D printing technology and maintained the perception one month after the program. The qualitative analysis revealed an expansion of the participants' problem-solving skills. The study implies that this learning program for 3D printing technology could help rehabilitation professionals reduce psychological concerns about this novel technology and enhance their clinical practices.
