Meskipun individu yang mengalami pengalaman sulit di masa kecil mendapatkanberagam dampak negatif, individu juga mungkin mengalami perubahan positif yaitupertumbuhan pascatrauma. Individu perlu melewati proses yang dipengaruhi berbagaifaktor untuk dapat mengalami pertumbuhan pascatrauma. Peneliti melakukan analisispada 396 data partisipan dewasa muda yang tinggal di berbagai wilayah di Indonesia,dengan tujuan untuk memeriksa hubungan ruminasi disengaja dan harapan dalammemprediksi pertumbuhan pascatrauma pada populasi individu dengan pengalaman sulitsebelum berusia 18 tahun. Partisipan mengisi kuesioner daring berupa Adverse ChildhoodExperience Questionnaire untuk mengukur kejadian sulit masa kecil, Event RelatedRumination Inventory mengukur ruminasi disengaja yang dulu dilakukan, Adult StateHope Scale mengukur keadaan harapan saat ini, dan Posttraumatic Growth Inventorymengukur besaran pertumbuhan pascatrauma. Hasil analisis regresi linear bergandamenunjukkan bahwa ruminasi disengaja dan harapan dapat memprediksi tingkatpertumbuhan pascatrauma secara positif dan signifikan. Berdasarkan temuan ini, harapandan ruminasi disengaja dapat ditumbuhkan dan diajarkan dalam program intervensi.

Despite survivors of adverse childhood experiences (ACE) have to face a variety of

negative effects, they also have the opportunity to experience positive changes known as

posttraumatic growth (PTG). Survivors of ACE have to pass through a long process

influenced by various factors. Analysis of 396 data on young adult participants living

across Indonesia were performed, with the aim to examine the effect of deliberate

rumination and hope in predicting PTG on a population of individuals experienced

adverse childhood before the age 18. Participants completed an online questionnaire

consisting of Adverse Childhood Experience Questionnaire measuring ACE’s score,

Event Related Rumination Inventory measuring past deliberate rumination’s level, Adult

State Hope Scale measuring the current hope’s level, and Posttraumatic Growth Inventory

measuring the degree of PTG. Multiple linear regression analysis indicated that deliberate

rumination and hope significantly predict the degree of PTG. Intervention strategies using

hope and deliberate rumination are further discussed.
