<![CDATA[The increasing use of digital communication among Generation Z has transformed the way romantic partners develop and maintain emotional intimacy, creating the need for a valid instrument to assess perceived digital intimacy. This study aimed to develop and provide preliminary psychometric evidence for a Perceived Digital Intimacy (PDI) scale designed for Indonesian Generation Z in romantic relationships. An instrument development and psychometric validation design was employed. The initial scale consisted of 40 items representing five dimensions: emotional closeness, self-disclosure, trust, sense of connection, and frequency and quality of digital communication, measured using a four-point Likert scale. Content validity was evaluated through expert judgment using the Content Validity Index (CVI), followed by a pilot study involving 30 participants to assess internal consistency. Construct validity was examined using Confirmatory Factor Analysis (CFA) with data collected from 150 respondents. One item was removed after content validation, resulting in 39 retained items. Cronbach's alpha coefficients ranged from 0.764 to 0.914 across dimensions. CFA indicated χ² = 1073 (df = 564, p < .001), CFI = 0.844, TLI = 0.826, SRMR = 0.097, and RMSEA = 0.077 (90% CI = 0.070–0.084). These findings provide preliminary evidence supporting the construct validity and reliability of the instrument while indicating the need for further refinement before broader application.]]>
