Relatedness needs and negative fantasies as the origins of obsessive thinking in romantic relationships

Surprisingly little experimental research has been conducted regarding the origins of obsessive thinking. Based on prior research on basic psychological needs (Sheldon and Gunz in J Pers 77(5):1467–1492, 2009) and future fantasies (Kappes and Oettingen in J Exp Soc Psychol 47(4):719–729, 2011), we proposed that a threat to the need for relatedness increases obsessive thinking about a romantic partner (i.e., a need-relevant target) when combined with a negatively valenced future fantasy about the partner. We tested this hypothesis in three experiments: Experiment 1, administered online, used a meta-cognitive relatedness threat manipulation, a scenario-based fantasy valence manipulation, and a measure of obsessive thinking. Experiment 2 used a modified fantasy valence manipulation, a new obsessive thinking measure, and a measure of romantic proximity-seeking. Experiment 3 used cyberball to manipulate relatedness threat in the lab. An internal meta-analysis revealed that threats to relatedness (vs. no threat) and negative fantasies (vs. positive fantasies) both led to small increases in obsessive thinking; however, inconsistent evidence emerged for the hypothesized threat-by-fantasy valence interaction.
