Summary of Studies Focusing on Monetary Discounting and Sexual Outcomes

Author/Year	N	Population	Delay	Probability	Primary Outcome(s)
Black et al., 2009	51	Adults in Outpatient Community Mental Health Treatment	Money	-	Trend towards an association between greater monetary delay discounting and higher sexual risk taking.
Celio et al., 2016	126	Emergency Department Patients	Money	-	Participants with greater monetary delay discounting showed a stronger correlation between alcohol expectancy variables (specifically, alcohol-induced sexual risk-taking and enhanced sexuality) and the percentage of recent unprotected sex events that co-occurred with alcohol use.
Cheng & Chiou, 2018	122/72	Undergraduates	Money	-	Exposure to attractive opposite-sex photos increased monetary delay discounting in male, but not female, participants. Changes in monetary delay discounting mediated increases in hypothetical cyber delinquent behavior following exposure to high valence sexual stimuli.
Chesson et al., 2006	1042	Adolescents and Young Adults	Money	-	Monetary delay discounting was associated with early age of sexual debut and multiple sexual partners in the past 6 months.
Gardiner et al., 2018	177	Adolescents in a Juvenile Justice Program	Money	-	Greater activation in brain regions relevant to reward during a monetary delay discounting was associated with lower levels of sexual risk behavior.
Jones & Sullivan, 2015	1402	MSM	Money	-	Greater monetary delay discounting was associated with greater odds of reporting 3 or more unprotected anal intercourse partners in the past year.
Jones & Sullivan, 2016	1332	MSM	Money	-	Greater monetary delay discounting was associated with unprotected anal intercourse, but only in men age 18–24 and not men 25 years old or older.
Kahn et al., 2015	219	Adolescents	Money	-	Monetary delay discounting played a mediating role in the relationship between parent-adolescent relationships and risk sexual behavior for adolescents scoring low on a self-control measure.
Khurana et al., 2012	347	Adolescents	Money	-	Monetary delay discounting was associated with earlier age of sexual debut.
Lawyer & Mahoney, 2018	296	Young Adults	Money	Money	Greater monetary delay discounting was associated with more frequent sexual risk behaviors, whereas lower monetary probability discounting was associated with more frequent sexual risk behaviors.
MacKillop et al., 2015	127	Emergency Department Patients	Money	Money	Greater monetary delay discounting was associated with a greater percentage of recent (past 90 day) unprotected sex co-occurring with alcohol use. Monetary probability discounting was not associated with unprotected sexual activity.
Negash et al., 2016	123/37	Undergraduates	Money	-	Greater monetary delay discounting was significantly associated with more pornography viewing in the past 30 days. Abstinence from pornography use decreased monetary delay discounting.
Reimers et al., 2009	42,863	Adults	Money	-	Greater monetary delay discounting were associated with earlier sexual debut.
Sparks et al., 2014	791	Adolescents	Money	-	Greater monetary delay discounting was associated with history of and past month casual sexual intercourse in adolescent sample.
Wilson & Daly, 2004	209	Undergraduates	Money	-	Viewing opposite-sex faces rated as attractive significantly increased monetary delay discounting in men, whereas a smaller and not significant increase was observed in women. No changes in monetary delay discounting were observed following viewing of opposite-sex unattractive faces.
Wray et al., 2015	113	Undergraduate (male)	Money	-	Monetary delay discounting was not significantly related to unprotected sex intentions under control conditions or following alcohol administration (target BAC of .08%) and autonomic arousal (recumbent bike exercise).
