"In my defense, only three hours on Instagram": Designing Toward Digital Self-Awareness and Wellbeing

Screen use pervades daily life, shaping work, leisure, and social connections while raising concerns for digital wellbeing. Yet, reducing screen time alone risks oversimplifying technology’s role and neglecting its potential for meaningful engagement. We posit self-awareness – reflecting on one’s digital behavior – as a critical pathway to digital wellbeing. We developed WellScreen, a lightweight probe that scaffolds daily reflection by asking people to estimate and report smartphone use. In a two-week deployment with college students (N=25) focused on generating formative insights, we examined how discrepancies between estimated and actual usage shaped digital awareness and wellbeing. Participants often underestimated productivity and social media while overestimating entertainment app use. They showed a 10% improvement in positive affect, rating WellScreen as moderately useful. Interviews revealed that structured reflection supported recognition of patterns, adjustment of expectations, and more intentional engagement with technology. Our findings highlight the promise of lightweight reflective interventions for supporting self-awareness and intentional digital engagement, offering implications for designing digital wellbeing tools.

💡 Research Summary

The paper investigates whether fostering digital self‑awareness can improve wellbeing, moving beyond the common “use less” paradigm in digital‑wellbeing research. The authors introduce WellScreen, a lightweight daily probe that asks participants to estimate their smartphone use at the start of the day, update the estimate at night, and then compare it with automatically logged actual usage. In a two‑week field study with 25 college students, the authors examined three research questions: (1) how users’ estimates differ from reality and what explains the discrepancy; (2) how a reflective tool influences self‑reported wellbeing and understanding of digital wellbeing; and (3) how users perceive the tool’s usefulness and how it supports digital self‑awareness.

Quantitative results show a systematic bias: participants tended to underestimate time spent on productivity and social‑media apps while overestimating entertainment app usage. The “estimate‑actual gap” (E‑A gap) was linked to several affective outcomes. Smaller gaps correlated with higher satisfaction and a stronger sense of self‑control, yet also with modestly higher stress and perceived difficulty in adhering to personal goals. Importantly, participants reported a 10 % increase in positive affect after the intervention. Usability scores (SUS ≈ 80, IAM ≈ 14) indicated moderate perceived usefulness.

Qualitative interviews uncovered three mechanisms through which WellScreen supported self‑awareness. First, the structured daily log made usage patterns concrete, enabling pattern recognition. Second, visualizing the gap between estimated and actual use prompted users to adjust unrealistic expectations about their digital habits. Third, this heightened awareness encouraged more intentional engagement—participants began to set clearer purposes for app use, limit usage in specific contexts, or re‑frame certain activities as purposeful rather than wasteful.

Design implications derived from the study include: (a) embedding an estimate‑actual comparison feedback loop as a core interaction to surface users’ cognitive biases; (b) providing a hybrid interface that combines quantitative visualizations with free‑form textual reflection, allowing users to link emotions, goals, and usage data; and (c) offering flexible goal‑setting and adjustment features so users can align technology use with personal values and evolving contexts.

The authors acknowledge limitations: the sample is small, homogeneous (college students), and the study duration short, which restricts generalizability and prevents assessment of long‑term behavioral change. Data were collected only from smartphone OS metrics, potentially missing background app activity. Future work should involve larger, more diverse populations, longer deployments, and multi‑device tracking to capture a fuller picture of digital habits.

In sum, the study provides empirical evidence that lightweight reflective interventions can cultivate digital self‑awareness, modestly improve positive affect, and support more intentional technology use. By focusing on the estimate‑actual gap rather than merely restricting screen time, the research offers a promising direction for HCI designers seeking to create digital‑wellbeing tools that empower users rather than constrain them.
