Introduction
Majority, above 80 %, of kidney transplantation in Japan is living-related kidney transplantation (LRKT). Mood disturbance such as depression is the most common psychological problem in recipients with LRKT (Kimmel et al., 2007) and is likely to be related to treatment adherence as well as quality of life (Akman et al., 2007). As physical factors, kidney function decline directly deteriorate mood states (Chilcot et al., 2014), but meta-analytic review pointed out that as psychological factors, cognitive appraisals (d=0.46) and coping strategies (d=0.31) are main relieving factors in patients with end-stage renal disease and requiring dialysis (Chan et al., 2011). Current study aims to investigate relationship between cognitive behavioral factors and kidney function on mood states in recipients with undergoing LRKT.

Methods
Participants were total of 110 recipients with undergoing LRKT within a week (female=30, age: M=47.38, SD=12.50). Data of gender, age, and hemodialysis history, serum creatinine level for kidney function measure were obtained from their medical chart. Participants were asked to fulfill following measurements: 1) Profile of Mood States-short version (POMS) Japanese version (Yokoyama, 2005), 2) Cognitive Appraisal Rating Scale (CARS; Suzuki & Sakano, 1998), 3) Tri-axial Coping Scale (TAC-24; Kamimura et al., 1995). This study was authorized by the ethical committee of the hospital obtained data.

Results
A stepwise multiple regression analysis revealed that cognitive appraisals' subscales (Threat appraisal: β=.25, p < .05; Controllability: β=-.33, p < .01) were significantly related to mood states (Adjusted R 2=.197, p < .01). On the contrary, hemodialysis history, serum creatinine level, and coping strategies were not significantly related to mood states.

Conclusion
These results revealed that cognitive appraisals might be the better mediator factor than kidney function and coping strategies on mood states for LRKT recipients especially before transplantation. LRKT is one of the life-threating events, but still cognitive appraisals have influence on mood states as psychological factors. Mood states are likely to affect quality of life and treatment adherence (Akman et al., 2007) which are invaluable to LRKT recipients. Therefore, besides as psychological treatments targeting on mood states, cognitive behavioral therapy focusing on cognitive appraisals seemingly is effective treatment as kidney medical treatments for LRKT recipients.Successful LRKT dramatically enhance recipients’ physical condition and that also possibly have influence on mood states. Future longitudinal research need to investigate how cognitive appraisal before LRKT would affect mood states after successful LRKT.
