# Attachment style and its impact on connection to God in individuals with brain injury: behavioral and lesion-based findings

## TL;DR

This study explores how attachment style influences a person's connection to God, especially in those with brain injuries, and identifies specific brain regions involved.

## Contribution

The study is the first to directly test how attachment style affects neural correlates of connection to God in individuals with traumatic brain injury.

## Key findings

- Secure attachment style is associated with stronger connection to God in individuals with brain injury.
- Damage to the right orbitofrontal cortex correlates with stronger connection to God in those with secure attachment.
- Attachment style influences both behavioral and neural aspects of connection to God.

## Abstract

Attachment style shapes one's connections with important figures in their life. One such unique relationship is the connection to God (CTG), which may be shaped by attachment style. Stronger CTG has been associated with secure attachment, yet the neural mechanisms underlying this relationship remain unclear. While previous research has implicated the prefrontal cortex (PFC) in CTG, findings have been mixed and may depend on attachment style—an idea that has yet to be directly tested. This study aimed to (1) examine whether individuals with a secure attachment style report higher levels of CTG compared to those with a non-secure attachment style, and (2) identify the brain regions associated with CTG in individuals with secure vs. non-secure attachment. We assessed attachment style and CTG in a sample of male combat veterans (N = 150), the majority of whom had focal traumatic brain injuries (pTBI; N = 119). Brain imaging (CT scans) was also obtained. Behaviorally, after controlling for age, years of education, and brain volume loss, individuals with a secure attachment style reported stronger CTG. Voxel-based lesion-symptom mapping revealed that damage to the right orbitofrontal cortex was associated with stronger CTG in individuals with secure—but not insecure—attachment. These findings suggest that attachment style shapes CTG at both behavioral and neural levels. Moreover, they highlight the potential role of attachment style in TBI recovery, offering insights that could inform spiritually integrated therapeutic interventions and support strategies.
