Pathological gambling harms individuals who gamble as well as their romantic partners. This study explored how it affects the quality of romantic relationships and attachment bonds between partners. The researchers recruited ‘clinical’ couples, where one partner had gambling disorder and the other did not. They compared the ‘clinical’ couples to ‘control’ couples, where neither partner had gambling disorder. Both partners in ‘clinical’ couples reported having a lower quality romantic relationship. This included more conflict, and less helpfulness and security. Both partners in ‘clinical’ couples also reported more anxiety and avoidance in their attachment bond to their partner.
