Evaluation
Our participants are asked to complete 2 questionnaires which are pretest and post-test. Pretest is completed before the start of exhibition and post-test is completed two weeks after the exhibition which means right after the homework session.
The content of pretest and posttest consisted of 4 parts: Love Language Knowledge Test (Nichols et. al., 2018), Trait Affection Scale (TAS) (Chen & Chen, 2023), the selected items from Dyadic Adjustment Scale (DAS) (Nichols et al., 2018; Shek, 1995) and feedback questions about the exhibition and homework session.
Details are as follow:

Results
In total, 30 pairs of couples completed both the exhibition and homework session. Generally, all participants agreed that the exhibition had a positive effect on communication within their relationship (M=4.75) and the homework session could help them to understand different ways of loving effectively (M=4.78).
There was a significant increase in love language knowledge test from pretest (M=12.0, SD=4.02) to posttest (M=14.4, SD=2.91); t(59)=6.66, p<.001.
There was a significant increase in TAS between pretest (M=79.5, SD=18.2) and posttest (M=92.8, SD=11.1); t(59)=5.15, p<.001.
There was a significant increase in DAS between pretest (M=49.1, SD=13.29) and posttest (M=56.4, SD=9.8); t(59)=3.95, p<.001.
Overall, it indicates that after exhibition and homework session, participants have a higher knowledge about love language, an increased affection with their partner and improved overall relationship satisfaction.




Moreover, we found that the increase in love language knowledge and trait affection exchange is positively correlated, r(58)= .829, p<.001, which aligns with our expectation that knowing more about love language can positively affect daily affection exchange.
Besides, the increase in trait affection exchange and dyadic satisfaction is positively correlated, r(58)= .816, p<.001. Change in trait affection given and received together predicts 69.0% of the change in dyadic satisfaction and cohesion, p<.001.
