Abstract
Smart phone addiction (SMA) is recognized as a health risk and is often linked with sleep disruption and psychological distress. This study assessed the prevalence and inter‐relationships of SMA, sleep quality and mental health parameters‐including self‐belief, self‐esteem, hopelessness and emotional stability‐among MBBS students. A cross‐sectional study was conducted among 380 MBBS students chosen randomly at Medical College, Kolkata. Data were collected using a structured, pre‐tested questionnaire incorporating the Depression Anxiety Stress Scale and a modified SMA Scale. Statistical tests included chi‐square tests, t‐tests, correlation and regression, with significance set at p = 0.05. Prevalence of depression, anxiety and stress were 64.7%, 64.7%and 49.5%, respectively; 53.2% had SMA and 55% reported poor sleep. More than half of the participants reported low self‐belief (50.5%), low self‐esteem (55.8%), hopelessness (55.8%)or emotional stability (54.5%). SMA correlated positively with depression, anxiety, stress and sleep disturbance and negatively with self‐belief and self‐esteem (p < 0.01). Significant risk factors included living away from one’s parents, reserved category status, allergies and gastrointestinal upset. Physical activity was protective, inversely related to SMA, sleep disturbance and psychological morbidity. Novel associations emerged between SMA and hopelessness, alongside evidence of bidirectional pathways linking poor sleep with distress. SMA, poor sleep and psychological morbidity are highly prevalent among medical students. By incorporating self‐belief and hopelessness as new dimensions, this study highlights the need for holistic interventions that combine digital hygiene, resilience training and physical activity.
