Key Points

  • 本研究は、若年層がスマート音声アシスタント(SVAs)でプライバシーを判断する際の「リスクと便益」「コントロールと受容」の対立を、ネゴシエーション(交渉)として捉える枠組みを提案しています。
  • 調査データ469人(カナダ、16〜24歳)を用いて、複合指標であるRisk-Benefit Tension Index(RBTI)とControl-Acceptance Tension Index(CATI)を定義・測定し、これらがプライバシー保護行動と有意に関連することを示しました。
  • SVAsの利用頻度が高い層ほど「便益優位」かつ「受容に傾いた」プロファイルになりやすく、利便性主導の利用は「コントロール感の低下」と引き換えになりうると示唆しています。
  • 本研究はプライバシーのパラドックスを「矛盾」ではなく「圧力間の交渉プロセス」として再解釈し、短い測定アプローチで対立要因の組み合わせを捉える見方を提供します。

Abstract

Smart Voice assistants (SVAs) are widely adopted by youth, yet privacy decision-making in these environments is often characterized by competing considerations rather than clear-cut preferences. While our prior research has examined privacy risks, benefits, trust, and self-efficacy as distinct predictors of behavior, less attention has been paid to how these factors combine into higher-level tension that shapes privacy outcomes. This study introduces a negotiation-based framework for understanding youth privacy decision-making with SVAs by operationalizing two composite indices: the Risk-Benefit Tension Index (RBTI) and the Control-Acceptance Tension Index (CATI), using survey data from 469 Canadian youth aged 16-24. We examine the distribution of these indices and their relationship with privacy-protective behavior and SVA usage. Results show that both indices are meaningfully associated with protective action. Frequent SVA usage exhibits more benefit-dominant and acceptance-leaning negotiation profiles, suggesting that convenience-driven engagement may come at the expense of perceived control. By reframing privacy decision-making as a process of negotiation rather than inconsistency, this study offers a complementary perspective on the privacy paradox and provides a compact measurement approach for capturing how youth navigate competing privacy pressures in voice-enabled ecosystems.
