Abstract
Human mate selection has been investigated for decades (Buss & Barnes, 1986; Symons, 1979; Westermarck, 1891) and has, for instance, focused on mating strategies (e.g., Buss & Schmitt, 1993) and mating preferences (e.g., Antfolk, 2017; Kenrick & Keefe, 1992). Still, most of these studies assume that individuals generally enjoy access to a pool of potential mates and that only personal characteristics or sexual competition limits mating success. There are, however, individual differences in our social contexts—for example, the sex ratio (e.g., the number of men pursuing the number of available women) and how many potential mates we meet in our everyday lives—and these differences affect our mate access (Stone et al., 2007): Even individuals who are highly desirable mates will have limited mate access if they are, for instance, living in a context with very few available partners.
Difficulties in finding a mate increase the risk of several negative consequences, such as loneliness (De Jong-Gierveld & Aalberts, 1980), decreased life satisfaction (Bailey & Snyder, 2002), reduced well-being (Gutiérrez et al., 2005), and increased outgroup hostility (Antfolk et al., 2018). Because of this, a full understanding of the factors affecting mating success is needed.
The Role of Social Context
We argue that two components need to be addressed concerning contextual mate access. First,
Second, mate access also consists of the
In sum, we argue that the individual social context, that is, the number of engagements we have with other people in general, affects individual mate access in interaction with the individual’s own characteristics and that this is the result of both the frequency of preferred encounters and the perceived possibilities. The more interactions we have in our social context, the more often we will experience preferred encounters and, accordingly, perceived possibilities. Our perceived possibilities are, therefore, related to the number of people we meet in our social context in general but even more so to our preferred encounters.
Individual Differences
Irrespective of gender, age, and sexual orientation, mate value (i.e., individual characteristics affecting the capacity to find and keep mates; Waynforth, 2001) and sociosexual desire (i.e., an individual’s desire for and interest toward uncommitted sexual relationships; Simpson & Gangestad, 1991) are two aspects related to mate access. Although mate access is not necessarily directly affected by mate value, an individual with high (vs. low) mate value will—all other things equal—be perceived as more attractive (e.g., Little et al., 2006) and is, therefore, expected to perceive more possibilities and to be able to more successfully convert preferred encounters into actual mating opportunities (Landolt et al., 1995). Sociosexual desire is, on the other hand, expected to moderate the association between mate access and negative affect: Individuals with high sociosexual desire will more actively seek mates and, consequently, experience stronger negative affect regarding poor mate access compared to individuals with low sociosexual desire (Vrangalova & Ong, 2014). Because of this, we also investigated the relationships between mate value, sociosexual desire, context-dependent mate access, and negative affect.
The Current Study
We created and evaluated a self-report questionnaire for measuring context-dependent mate access. To measure mate access, we designed 6 items to measure preferred encounters and 7 items to measure perceived possibilities. We also investigated associations between mate access and related concepts, making the following predictions: Individuals in social contexts including more (vs. less) frequent interactions with others will experience more (a) preferred encounters and (b) perceived possibilities, but (c) more frequent interactions with others will be more strongly associated with preferred encounters (vs. perceived possibilities). Individuals reporting more (vs. less) (a) preferred encounters and (b) perceived possibilities will report less negative affect, but (c) perceived possibilities (vs. preferred encounters) will be more strongly associated with negative affect. Individuals with high (vs. low) mate value will be better able to convert their preferred encounters into perceived possibilities. Individuals with high (vs. low) sociosexual desire will report more negative affect as a consequence of few perceived possibilities.
Moreover, we explored differences due to gender, relationship status, and sexual orientation.

Respondents and Procedure
We created an online survey and collected data in spring 2019 by targeting Finnish adults on Facebook. Our aim was to gather responses from 250 men and 250 women. The final sample consisted of 528 respondents (268 women, 252 men, and 8 other), ranging from 18 to 77 years old (
Of the 794 individuals who started the survey, we included only those who had answered all pertinent items. The completion rate was 66.5%, with most dropouts occurring before or directly after providing demographic information. The dropout rate was similar in all genders. Respondents completed the survey in, on average, 12 min and 40 s.
Measures
We designed measures for the social context, mate access, and negative affect regarding poor mate access. We included validated scales to measure self-perceived mate value and sociosexual desire. See Supplementary Material for original items and response options regarding social context and negative affect.
Mate access
We first devised 13 questions that in various ways probed an individual’s mate access. To avoid overlap, we inspected scales connected to mate value and sociosexual orientation (Edlund & Sagarin, 2014; Fisher et al., 2014; Kirsner et al., 2003; Landolt et al., 1995; Penke & Asendorpf, 2008). After this, we gathered feedback from psychology students in two steps and edited the items accordingly.
We partitioned the items into two thematic blocks. In the first block, we probed respondents about how many potential partners the respondents meet and talk to on an average day or during a normal weekend. In the second block, we probed respondents about how often they receive invitations and how they evaluate their chances of finding a partner within a specific time frame. Each item was rated on a 4-, 5-, or 7-point Likert-type scale.
In the questionnaire, we defined a “potential partner” as any individual one might be sexually or romantically interested in, considering their gender and age. We instructed respondents to answer as if they were single even if they currently were in a relationship. As we were not interested in measuring online-only relationships, we asked respondents not to count people they only meet online. However, online relationships that had later evolved into offline relationships were counted. We included both items about mate access to sexual and to romantic relationships, as preferences for short-term (e.g., Schmitt, 2005) and long-term mates (e.g., Buss et al., 2001) tend to differ.
Social context
To measure the social context of respondents, we inquired about how many adults the respondents meet during a common workday, in their spare time during a full week, and when seeing friends and acquaintances during a full week. Each item was rated on a 7-point Likert-type scale.
Negative affect
To measure the respondents’ negative affect regarding poor mate access, we asked the respondents about how much sadness, frustration, anger, and shame they felt as a result of their mate access regarding both sexual and romantic relationships. Each item was rated on a 5-point Likert-type scale.
Mate value
We used the Mate Value Scale (Edlund & Sagarin, 2014) to measure the respondents’ self-perceived mate value. The scale consists of items designed to measure one’s desirability as a mate, and responses are given using a Likert-type scale. The scale has demonstrated adequate psychometric properties (Edlund & Sagarin, 2014).
Sociosexual desire
We used 3 items from the revised Sociosexual Orientation Inventory (SOI-R; Penke & Asendorpf, 2008) to measure respondents’ sociosexual desire (i.e., an individual’s desire for and interest toward uncommitted sexual relationships; Simpson & Gangestad, 1991). The SOI-R is a measure of 9 items, of which three assess sociosexual desire. Responses are given using a Likert-type scale. The SOI-R has demonstrated adequate psychometric properties (Penke & Asendorpf, 2008).

Correlations
We first investigated correlations between all items (items are presented in Appendix and correlations in Figure 1). The correlations indicated the existence of two clusters: Correlations between the 7 items designed to measure preferred encounters (E) were high and positive, as were correlations between the 6 items designed to measure perceived possibilities (P).

CFA
We first compared the conceptual two-factor model with a one-factor model, in which the between-factor correlation was constrained to 1. Compared to the one-factor model, the two-factor model showed significantly better fit, Δχ2(1) = 211.00,

Measurement invariance
We then investigated measurement invariance across women and men, as well as single respondents and respondents in relationships. For a few items, a response option was not used by a group (i.e., the highest value for 1 item for the sex analysis was not used by men, and the highest value for 5 items for relationship status analysis was not used by singles). In these cases, we coded the highest value in the other group as the second highest value to unify the range across groups. The analyses showed that the two-factor model met criteria for scalar invariance across men and women and criteria for strict invariance across single respondents and respondents in a relationship (see Supplementary Table 4 for statistical details).
Social Context and Negative Affect
We used latent analyses to test the associations between mate access, social context, and negative affect (Figure 2), as this allowed us to also inspect the measurement model of the self-constructed items also for social context (C) and negative affect (A). The first model, in which we regressed preferred encounters and perceived possibilities on social context (C), showed appropriate fit, χ2(85) = 305.34,

The right model shows negative affect (A) regressed on E and P. For C, E, and P, higher values indicate better access to mates. For A, higher values indicate more negative affect. ***
Scale Construction
Factor scores and composite scores were highly correlated, and composite scores demonstrated sufficient reliability (Table 3). This suggests that mean composites could be used without much information loss.

Validation Against Mate Value and Sociosexual Desire
After this, we investigated the theorized associations between mate access, mate value, and sociosexual desire using composite scores (Table 4). We first tested the relationship between preferred encounters and perceived possibilities, when also considering mate value. When including mate value, preferred encounters were no longer associated with perceived possibilities (

Discussion
We developed and evaluated a self-report questionnaire for measuring mate access in 528 adult women and men. The final scale consisted of 12 items, divided into two conceptual blocks, measuring preferred encounters and perceived possibilities.
Main Findings and Interpretations
We found support for the functionality of the mate access items, and the results showed that mean composite scores can be used without much information loss. As expected, respondents with lower mate access reported stronger negative affect due to poor mate access. Preferred encounters were positively associated with perceived possibilities and few perceived possibilities with negative affect. When controlling for the association between perceived possibilities and negative affect, preferred encounters did not predict negative affect, suggesting that the association between context-dependent mate access and negative affect was fully due to the perceived possibilities of finding a mate.
Individual Differences
Mate value predicted perceived possibilities even after controlling for the number of other individuals the respondents reported meeting. This suggests that individuals who see themselves as more appealing also perceived more possibilities irrespective of context. The interaction between mate value and preferred encounters was not statistically significant. However, a possible explanation for this could be that preferred encounters are dependent on mate value, so that individuals with high mate value are better able to convert their preferred encounters into perceived possibilities. Moreover, the association between few perceived possibilities and negative affect was stronger in respondents with high sociosexual desire, suggesting that low mate access paired with a high sociosexual desire yielded particularly strong negative affect.
Limitations and Recommendations
There are some notable limitations. First, we asked respondents not to report online encounters. It is unclear whether respondents complied with this request. Second, the definition of a “potential partner” might have been ambiguous, and respondents might have experienced difficulties in remembering the definition throughout the questionnaire. To mitigate this, we repeated the definition 4 times. Third, we asked respondents to answer as if they were single, even if they were in a relationship. Despite our analyses showing that the scale was used similarly for single respondents and respondents in a relationship, singles reported lower mate access. One explanation might be that respondents in relationships have higher mate value.
Future studies should validate the scale against other constructs and in other populations. For instance, mate access, negative affect, and mate value might covary in environments that differ from the studied population. Future studies should also investigate mate access online, since online dating services enable us to assess tens of thousands of potential mates (e.g., Lenton et al., 2008), but little is known about how equivalent online mate access and real-life mate access is in terms of their effects on well-being.
Conclusions
The findings from this study support the utility of the two-factor Mate Access Scale. In line with theory, mate access was predicted by social context, and low mate access was associated with negative affect. Moreover, mate access measures a different aspect of mating than mate value and sociosexual desire. This suggests that the Mate Access Scale could be used in addition to existing measures to better understand all aspects of human mating and its psychological and behavioral correlates.
