Locus of Control and Mental Health: Human Variation Complicates a Well-Established Research Finding

Area of Science:

• Psychology
• Sociology
• Cross-cultural studies

Background:

• Locus of control (LoC) typically links internal LoC to positive mental health in Western settings.
• Cross-cultural research on LoC and mental health, especially in Global South contexts, is limited.
• This study examines LoC in rural Haiti, a setting marked by structural violence and belief in supernatural agents.

Purpose of the Study:

• To investigate the relationship between sent spirit-related locus of control (LoC-S) and mental health in rural Haiti.
• To explore how cultural beliefs about supernatural agents influence mental health outcomes in a context of limited personal control.

Main Methods:

• A community-based survey was conducted in rural Haiti with 322 participants.
• The survey assessed sent spirit-related locus of control (LoC-S) and mental health indicators, including depressive and anxiety symptoms.
• Statistical analyses explored the interaction between LoC-S, daily stressors, and mental health outcomes.

Main Results:

• High daily stressors were associated with high depressive and anxiety symptoms irrespective of LoC-S.
• For individuals with low-to-moderate stressors, external LoC-S (attributing outcomes to external forces like spirits) correlated with lower depressive symptoms.
• This external LoC-S association with reduced symptoms suggests a role for blame displacement via supernatural explanations.

Conclusions:

• In contexts of extreme structural violence, external LoC aligns better with lived realities where individuals have limited control.
• An external LoC, particularly when mediated by supernatural beliefs, may buffer against negative mental health outcomes by facilitating blame displacement.
• Findings highlight the importance of cultural context in understanding the LoC-mental health relationship.
