Purpose: Young adulthoods engaging in sexual intercourse are at elevated risk for depression, but it is not clear at what point of adulthood development this connection ceases to be significant. Depression is a highly prevalent mental health problem in young adulthoods compared to middle age, especially among girls. This study examines the association between self-reported depression and sexual relationships across the age of young adulthood and separately in boys and girls. The study hypothesises that there will be significant positive correlations between Sexual intercourse and Depression among young adults. It is also hypothesised that there will be significant differences between male and female regarding sexual relations among young adults. These hypotheses are based on the assumption that individuals who possess higher levels of depression and sex related problems are more likely to experience negative emotions, which are associated with mental health issues. Moreover, the study aims to investigate whether there are any need of sex therapies for Sex related problems and self reported depression among young adults. To test these hypotheses, the study utilises two psychometric tools: The Dyadic Sexual Communication Scale (DSC), The Beck Depression Inventory (BDI). The Dyadic Sexual Communication Scale (DSC) is a Likert-type scale assessing respondents ’perceptions of the communication process encompassing sexual relationships. The original 13-item scale discriminated people reporting sexual problems from those not reporting sexual problems (Catania, 1986) and The Beck Depression Inventory (BDI) is a 21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression (Beck, et al., 1961). The results of this study have important implications for understanding the relationship between sexual relations and self reported depression among the young adults in comparison to male and female. Furthermore, identifying any potential gender differences can help inform interventions aimed at improving depression regarding sexual intercourse in young adults.
