The perception of lower mate availability was associated with decreased life satisfaction, but an oversupply of potential mates also made some uncomfortable (choice overload, especially of those who are good catches)

The Influence of Sex Ratio and Perception of Mate Availability on Psychological Health. Rosenbach, Naomi. Hofstra University, ProQuest Dissertations Publishing, 2022. 28774896. Aug 2021. https://www.proquest.com/openview/0e611481cbc3dbe91211f359da573e0c/1?pq-origsite=gscholar&cbl=18750&diss=y

Abstract: Pair bonding, or long-term adult romantic relationship, was advantageous in ensuring offspring survival and adult protection in the evolutionary environment, thus humans have evolved with strong mating and pair bonding motivations (Belsky, 1999; Fraley, Brumbaugh & Marks, 2005; Fraley & Shaver, 2000). Because successes and failures in meeting adaptive goals is correlated with emotional and psychological health (Nesse, 2016; Plutchik, 2003), decreased or thwarted mating opportunity should theoretically impact wellbeing. Sex ratio refers to the number of males relative to females in a given population and significantly influences mating opportunity. When sex ratio is skewed, the oversupplied sex experiences a dearth in mating opportunity (Guttengang & Secord, 1983). The minimal research that has been conducted in this area suggests that population sex ratio and mating opportunity influence wellbeing (Tucker & Mitchel-Kernan, 1989) yet more research is necessary to gain a better understanding of the psychological impact of sex ratio.

This study examined whether population specific sex ratio and perceived mate availability influenced a variety of mental health outcomes and dating strategies in the young adult, single, population. The main sample consisted of 647 participants (332 male and 315 female) who responded to an online survey with items measuring depression, anxiety, positive and negative affect, life satisfaction, self-esteem and mating flexibility. Mate value, religious and cultural beliefs were assessed as moderating variables. Additionally, some mating and commitment strategies were explored. The hypotheses that young adults who live in an area with less mate availability or who simply perceive there to be an undersupply of available mates would have more negative psychological outcomes were partially supported. Perceived sex ratio and actual sex ratio differentially impacted males and females. For males, perception of lower mate availability was associated with decreased life satisfaction, decreased positive affect, and decreased choosiness in mating criteria. For females, an actual oversupply of females was associated with decreased life satisfaction. Mate value was found to moderate the relationship between perceived sex ratio and anxiety, depression, and negative affect for both males and females. For those low in mate value, decreased opposite sex availability was associated with an increase in anxiety, depression, and negative affect. This pattern reversed for those high in mate value, where perceived increased opposite sex availability was associated with increased depression, anxiety, and negative affect. This latter, unexpected finding suggests that there may be psychological costs for those both high and low in mate value when there is an imbalance in sex ratio. Additionally, perceived sex ratio impacted some dating commitment strategies. For example, those who perceived there to be a dearth of opposite sex availability reported that they would be more “willing to settle for a less than ideal mate out of desperation”. These findings suggest that skewed sex ratio not only impacts sociological constructs such as mating strategies and behaviors but can also impact psychological constructs and individual wellbeing. These findings can help those in the clinical and counseling field better understand how sex ratio and mate availability influence wellbeing. Given that mate acquisition is a significant life goal for young adults, clinicians working with that population should assess for beliefs surrounding mating opportunity.
