Diary studies are a venerable research method employed across social sciences and user experience research. Participants record their activities, thoughts, and feelings over time, providing researchers rich qualitative data. This method is instrumental in contexts where longitudinal observation is critical to understanding the nuances of behaviors and experiences (Bolger, Davis, & Rafaeli, 2003).
Diary studies are similar to but also differ subtly from experience sampling methods (ESM) and ecological momentary assessments (EMA). Specifically, diary studies often involve individuals qualitatively recording what they do during the day or a period of time.
This method captures not only the subjective experience but also what individuals care most about and what occupies "the vast majority" of their "conscious attention" (Wheeler & Reis, 1991, p. 340).
The longitudinal nature of diary studies provides a window into the ebb and flow of daily life, offering insights that are often invisible in other research methods, although having similar strengths to ESM and EMA. Therefore, diary studies are invaluable for:
They document experiences as they occur, reducing recall bias (Scollon, Kim-Prieto, & Diener, 2003). This often occurs with one-off retrospective surveys, which can be inaccurate.
This method contrasts sharply with one-off surveys or follow-up interviews, which tend to rely on memory and can lead to misrepresentation of emotions or events. By promoting immediacy in reporting, a diary study delivers data that is often richer, more nuanced, and grounded in the participant’s actual moment-to-moment reality.
They can identify how context influences behavior (Shiffman, Stone, & Hufford, 2008). Because a diary study examines participants' lives as they live them, we can better understand the naturally occurring factors that influence behaviors.
With participants reflecting on their lives as they happen, diary studies can reveal the subtle, naturally occurring factors that shape behaviors—shedding light on elements such as stress triggers, motivation in different social contexts, and patterns of mood variation.
They provide a platform for participants to express personal reflections (Laurenceau & Bolger, 2005). A more free-form approach (as opposed to experience sampling forms or quantitative scales) enables one to more fully understand what individuals care about - and not merely what researchers are interested in.
Researchers can, therefore, gain insight into the participants' worldviews, experiences, and reflections, creating a rich tapestry of data that goes beyond merely quantifiable behaviors and uncovers the meaning participants attribute to their actions and interactions.
According to an article by Nielsen Norman Group, diary studies help explore research questions about long-term experiences and repetitive activities.
The article also shared that a diary study is applicable if you measure habits, attitudes, motivations, behavioral changes, customer journeys, channel or device usage, and external factors.
For this reason, diary studies can have wide-reaching applications:
They explore emotional and cognitive processes over time (Smyth & Stone, 2003). For instance, a more qualitative approach enables one to understand the subjective factors in creativity and creative days in a naturalistic context (Czerwonka, 2019).
This allows psychologists to understand creativity as a dynamic process influenced by daily experiences, motivation, mood, and social interactions, providing insights that might remain hidden in more structured, cross-sectional studies.
They track patient symptoms and treatment effects (Stone & Shiffman, 2002). For instance, recent research used a daily diary study to understand behaviors' physical and psychological functioning (Strahler, Nater, & Skoluda, 2020).
This continuous data collection allows healthcare professionals to identify symptom fluctuation patterns and pinpoint when treatments may need adjustment. Such insights support a holistic approach to patient care, enabling more personalized and responsive treatment plans that adapt to the patient's day-to-day realities.
This involves providing user feedback on product interaction in real-world settings (Rieman, 1993). As Google advocates, this is similar to using experience sampling to track how users engage with a product.
By allowing users to document their interactions, diary studies reveal context-specific issues, uncover how the product fits into different scenarios, and provide a more comprehensive view of user needs. This helps UX researchers and designers refine and adapt products that genuinely resonate with their audience, enhancing user satisfaction and product success.
ExpiWell’s app revolutionizes diary studies by digitizing the traditional pen-and-paper process used in diary studies. Using ExpiWell as a daily diary tool can offer the following benefits:
The app’s availability on major platforms such as iOS and Android Apps ensures participants can easily record entries. Moreover, the data recorded is end-to-end encrypted, so you do not need to worry about participants losing their physical diaries and inadvertently sharing personal information.
Traditional diary methods, which may rely on physical notebooks or unencrypted digital files, involve data loss or unintended disclosure risks. With ExpiWell, however, these risks are mitigated, ensuring that personal reflections remain secure and accessible only to authorized users with HIPAA and GDPR.
Real-time data capture through ExpiWell reduces errors associated with delayed reporting, which helps maintain data accuracy and integrity, an essential feature for high-quality longitudinal research.
By enabling participants to record their responses and reflections at the exact moment of experience, ExpiWell, as a daily diary tool, minimizes issues associated with delayed or retrospective reporting, which can introduce biases and inaccuracies. The immediacy of real-time entries prevents memory decay and ensures that participants capture authentic, nuanced reflections of their experiences.
ExpiWell supports various data formats from participants via our free mobile apps, enriching the quality of entries. Capture video, voice, photos, location, and more! Researchers have stressed the importance of digital capture in overcoming challenges in free-form writing (Carter & Mankoff, 2005).Integrating multimedia capabilities also enhances engagement, as participants have creative options for capturing their observations.
By allowing them to choose formats that best suit their experiences, ExpiWell makes capturing complex, multifaceted data that better reflects participants' daily realities easier.
With our convenient and easy scheduling, you can send nudges to participants to complete their daily diaries regularly.These automated reminders are especially helpful for studies spanning several weeks or months, where participant engagement might naturally wane.
Researchers can ensure that participants stay on track without feeling overwhelmed by scheduling prompts at specific times—whether daily, weekly, or around key events.
