The Digital Life Balance Scale: Psychometric Validation and Its Role in Smartphone Addiction, Anxiety, and Life Satisfaction in the Spanish Context

In the digital era, balancing digital and nondigital activities is crucial for psychological well‐being, underscoring the need for research to enhance health interventions. This study validates the Spanish version of the Digital Life Balance Scale (DLB‐Scale) and explores its associations with smartphone addiction scale (SAS), satisfaction with life (SWL), and generalized anxiety disorder (GAD) in a sample of 334 Spanish university students (M = 21.26, SD = 2.23; 72.5% women). The DLB‐Scale demonstrated strong internal consistency (Cronbach′s α = 0.87), satisfactory construct validity, and unidimensionality, as confirmed by confirmatory factor analysis (CFI = 0.99, TLI = 0.99, RMSEA = 0.07, SRMR = 0.008 after model adjustment). Strict gender invariance was established, enabling valid cross‐gender comparisons. Regression analyses revealed that higher DLB levels were associated with lower SAS ( r = −0.426) and GAD ( r = −0.182) and greater SWL ( r = 0.218). Notably, DLB explained 17.9% of the variance in SAS, compared to 4.5% in SWL and 3.0% in GAD. Additionally, network analysis highlighted DLB as a central construct with strong links to SWL and SAS, corroborating its indirect association with GAD. These findings establish the Spanish DLB‐Scale as a reliable tool for assessing digital balance in Spanish‐speaking populations. The study offers practical implications for interventions aimed at enhancing DLB to improve well‐being and reduce digital stressors.
