<![CDATA[Digital communication has positioned WhatsApp Groups as a key space for information exchange and coordination in residential communities. This study describes the intensity of WhatsApp Group use and residents’ quality of life, and analyzes the statistical effect of usage intensity on the quality of life of Cavana Garden Village residents. A quantitative cross-sectional survey was conducted. Eighty residents were selected purposively for the main study based on group-membership and usage-experience criteria, while 20 respondents took part in instrument testing. Likert-scale questionnaires measured frequency, duration, attention, and participation, as well as physical, psychological, social-relationship, and environmental domains. The data were analyzed using descriptive statistics and simple linear regression after parametric assumptions were assessed. Usage intensity was high (mean = 3.54), and overall quality of life was also high (mean = 3.43), although the psychological domain remained moderate (mean = 3.38). A regression coefficient of 1.174, t = 6.752, and p < .001 indicated a positive and statistically significant predictive association. R² = .369 means that the model explained 36.9% of quality-of-life variation, while 63.1% was attributable to other factors and error. Relevant, orderly, and participatory group use may support access to information, coordination, and social support. Because the design was cross-sectional and the sample was purposive, the findings do not establish causality and should be generalized only to an accessible population with similar characteristics.]]>
