Table 1_Depressive symptoms precede and drive problematic smartphone use in Chinese medica

Chinese medical graduate students were surveyed at two time points separated by six months. The dataset contains responses from 584 participants (mean age 30.47 years, 65.2% male) on the Smartphone Addiction Scale-Short Version and the 9-item Patient Health Questionnaire. The data was uploaded by Wenhao Lv on May 8, 2026, under a CC-BY-4.0 license.

Use Cases

• Conducting network analysis to identify bridging symptoms like 'concentration difficulties' (PHQ7) and 'fatigue' (PHQ4) between depression and problematic smartphone use.
• Building predictive models for problematic smartphone use susceptibility based on antecedent depressive symptoms, using features like 'can't stand not having a phone' (PSU4).
• Performing longitudinal analysis to test directional relationships between symptom clusters over a six-month interval.
• Identifying potential intervention targets for co-occurring disorders based on symptom-level influence within cross-lagged panel networks.

Strengths

• Includes longitudinal data from two time points separated by six months, allowing for analysis of temporal dynamics.
• Based on a sample of 584 medical graduate students with a defined mean age (30.47 years) and gender distribution (65.2% male).
• Uses validated clinical instruments: the Smartphone Addiction Scale-Short Version and the 9-item Patient Health Questionnaire.

Limitations

• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• Column-level documentation is absent; field semantics must be inferred after download from the provided DOCX file.
• The data is specific to Chinese medical students, which may limit generalizability to other populations or cultural contexts.
