Introduction:

Mate preference studies have been growing worldwide in recent years; however, the psychological tests used in this area have not been adequately adapted to Spanish-speaking contexts. This study aims to adapt to Spanish one of the most frequently used tests in human sexual selection: Ideal Partner and Relationship Scale (IPRS).

Method:

The adaptation included the following procedures: (1) Translation by peers; (2) Evaluation by experts; (3) Initial application / Validation (149 participants); (4) Analysis of psychometric properties; and (5) Confirmatory analysis from an independent sample (247 participants).

Results:

We proceeded to create the final version of the test in Spanish through the information collected. The analysis of the psychometric properties of the IPRS test indicates that the instrument retains stability and consistency similar to the original English version. This new version conserved the factorial structure, which includes five preference dimensions (physical attractiveness, warmth and trust, status and resources, intelligence, and social skills). Similarly, reliability indicators demonstrate good internal and temporal stability. Finally, the participant’s preference patterns are equivalent to what has been reported in cross-cultural mate research.

Conclusions:

The good properties of the collected evidence led to the conclusion that the adaptation of the Spanish IPRS test was successful, as a result of strict validation protocols.
