  Abstract:
  “Background: The social defeat hypothesis posits that chronic experiences of social exclusion and ostracism lead to elevated negative symptoms such as amotivation, anhedonia, and asociality. We tested this assumption in a prospective longitudinal study across Germany, Indonesia, and the United States (N = 962) assessed every four months over one year.
  
  Findings: Cross-lagged panel models demonstrated that ostracism prospectively predicted negative symptoms over time, while negative symptoms concurrently increased subsequent ostracism experiences.
  
  Conclusion: Findings provide strong multi-national evidence for a bi-directional longitudinal relationship between social exclusion and negative psychiatric symptoms, supporting social-inclusion interventions.”

  Abstract:
  “Background: The UCLA Loneliness Scale (ULS) is the gold standard for assessing loneliness, but cross-cultural validity and measurement invariance had not been systematically evaluated across Western and non-Western societies.
  
  Methods: Evaluated measurement invariance in 2,350 participants across Germany, Indonesia, and the United States across full and brief versions of the scale.
  
  Findings: A refined 6-item version (ULS-6) focusing strictly on social isolation satisfied full scalar measurement invariance across all three countries, whereas longer versions showed cross-national item bias.
  
  Conclusion: The ULS-6 is established as an optimal, psychometrically equivalent measurement tool for cross-cultural psychological and psychiatric studies on loneliness.”

(Eds.), Steering the cultural dynamics: Selected papers from the 2010 Congress of the International Association for Cross-Cultural Psychology. Melbourne: IACCP.

  Abstract:
  “Study Overview: Investigated how dyadic supervisory relationship quality (Leader-Member Exchange, LMX) fosters Organizational Citizenship Behavior (OCB) in Indonesian institutional environments. Results demonstrated that mutual trust, support, and respect between managers and employees significantly enhance prosocial workplace contributions, civic virtue, and organizational productivity beyond formal job duties.”

Psychotic Experiences and Related Distress: A Cross-national Comparison and Network Analysis Based on 7141 Participants From 13 Countries. Schizophrenia Bulletin, 44(6), 1185-1194. doi: 10.1093/schbul/sby087

  Abstract:
  “Background: Examined whether psychotic-like experiences (PEs) and their psychological distress differ between collectivistic low- and middle-income countries (LAMIC, n = 2,472) and individualistic high-income countries (HIC, n = 4,669).
  
  Findings: Endorsement rates of PEs were higher in LAMIC, but associated distress levels were significantly lower than in HIC. Network analysis showed that psychotic experiences were substantially less interconnected in LAMIC populations.
  
  Conclusion: Subclinical psychotic experiences are experienced as more benign and less distressing in collectivistic contexts, demonstrating that clinical risk assessments must account for cultural meaning and distress rather than symptom presence alone.”
