In empirical RLT studies, increase of self-esteem, "adult" and "nurturing parent" (in egogram)" was pointed out (Hosoi et al., 2002; Okamoto, 2006) . And in case studies, expressed emotions, insight, self-awareness were suggested as significant indicators of this therapy. But it is necessary so that qualitative studies with objective summary tool clarify long sentences. In this study, description codes for RLT are structured, and the applications are discussed. METHOD: Sentences extracted from 12 articles and 2 technical books about RLT were categorized by using KJ method. The codes were examined two steps of validity (correspondence, usability, frequency, clinical importance) by 3-5 researchers. And the reliability was confirmed by concordance rate of the coding by 7 researchers and graduate students. RESULT: As a result of classification, 15 codes for "letters to another" and 14 codes for "letter to self" were structured. The former consists of "anger/dissatisfaction", "dependence", "need/hope", "reflection/awareness", "care/thoughtfulness", "gratefulness", etc. The latter consists of "complaint/blame", "enmeshment", "advice/ opinion", "expectation/wish", "care", "comprehension/regard", etc. A rate of agreement in 2 people's cording (in arbitrary 3 in 7) is 82.2%, therefore, these cords need the use in more than 3 people. DISCUSSION: The codes are in practical use stage, and have following utilizations. a) Discovering patterns in letters, b) convert a description into variables, c) comparison of technique. Furthermore, it can be applied to RLT as a supporting tool for understanding. For example, ascertaining a fluctuation in the number of the cords leads to understanding of client's power of expression. ) and has used in many mental health surveys in the world. We only describe depression validity due to other data analysis of this study is still in processing. This study is a diagnostic study, conducted in 2009 at 5 psychiatric centers in 5 cities (Jakarta, Bandung, Yogjakarta, Surabaya and Makassar). The participants were minimum 18 years, were excluded if had severe dementia and mental retardation. All participants were administered by the MINI and followed by SCID as a reference test. The SCID interviewers were general doctor and who were following the postgraduate of psychiatry, the MINI interviewer were nursing student and nurse. Both of interviewers were blind about the respondent's diagnosis except for respondent from population. The data processing used computer with SPSS version 15 statistical program. There were 82 data analyzed in this study, consisted of 45 patients and 27 non patients from population, 41 males and 41 females. The sensitivity of depression is 0.66 and the specificity is 0.89. The positive predicted value is 0.33, the negative predictive value is 0.97 and positive likelihood ratio is 6. 3, negative likelihood ratio is 0. 37. The median duration of interview was 30 minutes for a completed MINI and 60 minutes for completed SCID. The validity of depression diagnosis in this study is good but it needs comprehensive interpretation. It seems that even though the sensitivity is above 0.50 ,the questions are more specific to diagnose depression. The positive predictive value is low due to lack of patients. The next analysis will be better by completed data from all sites. The experiences of the author, a psychologist, regarding clinical depression were analyzed in order to develop new research methods for behavioral medicine. The analysis focused on self-investigation, quantitative and qualitative approaches, and an evidence-based approach for the individual. In Period I (1994) (1995) (1996) (1997) (1998) (1999) (2000) , a female client was treated with cognitive behavior therapy (CBT) by a clinical psychology professor. In Period II (2000) (2001) (2002) (2003) (2004) (2005) , pharmacotherapy was conducted by a psychosomatician. In Period III (2005-present), CBT and holistic medical treatment were conducted by another psychosomatician. In the second year of Period III (Period III-2), to facilitate self-regulation, Self-Efficacy and Self-Evaluation Scales were developed with the following items: 1. Absorb fulfilling experiences, 2. Keep good memories, 3. Achieve the research goals, 4. Calmly express feelings, 5. Change one's mood to cope with or avoid stress, 6. Regulate drowsiness, 7. Assert own opinion, 8. Ward off unimportant things, 9. Keep appropriate distance from others, and 10. Keep good personal relationships. Items 1-6 were common to Periods III-2-III-5, whereas items 7-9 were used in Periods III-2 and III-3 and integrated into item 10 in Periods III-4 and III-5. In each session, the client rated her pre-practice self-efficacy and postpractice self-evaluation. Average self-efficacy and selfevaluation scores descended in the order of items 1, 2, 3, 5, 6, and 4. Self-efficacy and self-evaluation scores on items 7-9 increased from Period III-2 to Period III-3. Most of the problems occurred in the family and relatives area. The top three reasons for positive discrepancy of the scores (evaluation -efficacy) include fewer problems occurred, or there was less sensitivity to the problems, executed things in workplace or personal areas, and maintained good communications. Correlations among self-efficacy scores on items 1-3 and 5 were significant in Periods III-4 and III-5. These results suggest that the client became able to cope with the problems and stress. The significance of this research is discussed in relation to "clients as researchers." A limitation of self-reports for disease symptoms is recall bias including retrospective distortions of the respondents' experiences. To overcome this concern, ecological momentary assessment (EMA) and the day reconstruction method (DRM) have recently been used, but the validity of these methods has not been objectively examined. Therefore, the aim of this study was to investigate the validity of EMA and DRM by using physical activity level (PAL) as an objective external criterion. Twenty-two healthy undergraduates (age 21.9±2.6 yrs) wore a watch-type computer and recorded visual analog scales of fatigue and depressive mood at different EMA design; recorded momentary symptoms every two hours (time-based) and recorded the symptoms during the behavioral episode which was just finished when switching one behavior to another (episode-based). They also recorded the symptoms afterward according to the series of behavioral episodes they reconstructed (DRM) about the same days. PAL was obtained using an actigraph built into the watch-type computer. Multilevel modeling showed that the association between depressive mood recorded with time-based EMA and PAL averaged over 60 minutes around EMA recording was significantly negative (p= 0.002); however, depressive mood recorded with episode-based EMA and DRM had no association with PAL averaged over the period of corresponding episodes. As for fatigue, none of the methods showed significant association with averaged Pal. These results suggest that time-based EMA might have the validity against the objective PAL when assessing depressive mood in contrast to episode-based EMA and DRM. Though averaged PAL alone failed to confirm the validity of all three methods used in this study as assessment of fatigue, incorporating other PAL measures than a simple average might distinguish the validity of them and need to be investigated.
