ABSTRACT

The present study conceptualized and developed new measurement instruments to assess adolescents’ a) exposure to, b) liking, and c) posting of positive content on social media. By means of an integrative review of the literature, six focus groups and 14 in-depth interviews, 19 items were developed for each scale. Based on a cross-sectional study among 294 adolescents, EFA and CFA extracted two valid and reliable factors for exposure to positive social media content, one valid and reliable factor for liking positive social media content, and three valid and reliable factors for posting positive social media content. A short version of these three (multifactorial) scales was created and administered in a two-wave panel study among 1419 adolescents and in a cross-sectional study among 493 late adolescents. Test–retest reliability, structural validity, construct validity, and full metric invariance across age and gender were established for all short scales, except for the posting scale for which only partial metric invariance was achieved across gender.

摘要

本研究概念化并开发了新的测量工具来评估青少年的 a) 接触、b) 喜欢和 c) 在社交媒体上发布积极内容。通过对文献的综合回顾、六个焦点小组和 14 次深度访谈，每个量表制定了 19 个项目。基于对 294 名青少年的横断面研究，EFA 和 CFA 提取了 2 个用于接触正面社交媒体内容的有效和可靠因素、1 个用于喜欢正面社交媒体内容的有效和可靠因素，以及 3 个用于发布正面社交媒体内容的有效和可靠因素媒体内容。这三个（多因素）量表的简短版本是在一项针对 1419 名青少年的两波小组研究和一项针对 493 名晚期青少年的横断面研究中创建和管理的。重测信度、结构效度、
