Background There is a growing concern in the field of aesthetic surgery about the need to measure patients' expectations preoperatively. The present study was designed to develop and validate the Expectations of Aesthetic Rhinoplasty Scale (EARS), and to compare expectations between rhinoplasty patients with and without body dysmorphic disorder (BDD). Methods In total, 162 college students and 20 rhinoplasty candidates were recruited. The measures included the newly developed EARS, a measure of psychopathology, and demographics. The DSM-IV structured clinical interview for BDD was used to confirm the diagnosis in rhinoplasty patients. Results The EARS was constructed of six items based on their significant content validity. In the scale development phase, Cronbach's alpha was 0.87. The test-retest reliability coefficient of the scale was satisfactory (intraclass correlation coefficient, 0.94; 95% confidence interval, 0.82-0.98) over a four-week period. Scores on the EARS were significantly positively correlated with psychopathological symptoms (r=0.16; P<0.05). Moreover, comparison of EARS scores between BDD (M=25.90, standard deviation [SD]=6.91) and non-BDD rhinoplastic patients (M=15.70, SD=5.27) suggested that BDD patients held significantly higher expectations (P<0.01). Conclusions The expectations of aesthetic rhinoplasty patients toward surgery may play a crucial role in their postoperative satisfaction. While the value of patients' expectations is clinically recognized, no empirical study has measured these expectations in a psychometrically sound manner. The current study developed and validated the EARS. It may be easily used as a valid and reliable instrument in clinical and research settings.

1970년대 이후 현재까지 결혼관에 대한 대부분의 연구는 그 당시 결혼에 대한 생각들을 알아보기 위한 실태조사에 그치고 있다. 현대사회에 들어서면서 결혼에 대한 인식의 변화로 특히, 젊은이들의 결혼관은 많은 변화를 겪고 있는 것이 사실이다. 하지만 우리나라에서는 여전히 최근 서구의 결혼관이 많이 유입되어 있으나, 아직까지도 그 이면에는 과거 전통적인 제도적 결혼관이 뿌리박혀 있다는 것을 알 수 있다. 따라서 본 연구의 목적은 결혼관을 보다 과학적인 방법으로 발전시키려는 노력의 일환으로 한국형 결혼관 척도를 통하여, 현대 사회를 살아가고 있는 젊은이들의 가치관 혼재에 따른 갈등을 예측해보고, 기혼부부의 안정적이고 바람직한 가정형성을 위하여 성공적인 결혼과 결혼 전·후의 심리적인 문제들을 탐색해볼 수 있는 기회를 제공해보고자 한다. 275명의 대학생들을 대상으로 실시한 문항선정 예비연구와 1,283명의 기혼부부들을 대상으로 결혼관의 타당도와 신뢰도를 살펴본 결과는 다음과 같다. 본 연구의 한국형 결혼관 척도에서는 '전통적인 결혼', '성공적인 결혼', '결혼의 불합리성', '결혼의 필요성', '동거', '이혼 및 재혼'의 6개 요인이 추출되었고, 기존의 척도와도 높은 상관을 보였으며, 각 하위척도들의 신뢰도 계수는 Cronbach α=.63 에서 .88로 비교적 신뢰롭게 나타났다.

With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

Purpose: To develop the stress coping behavior measurement scale(SCBMS) for the workers in manufacturing industry. Methods: Developing of SCBMS was based on job stress and psycho-social health status. Job stress and psycho-social health status were estimated by using the Karasek's job content questionnaire (JCQ) and the general health questionnaire (GHQ-28), and the general characteristics for subjects were estimated by self-reported questionnaire and interview. Result: The subjects were 456 male workers who had never been occupationally exposed to hazardous chemical and other materials, was mean age 31.27 years and mean work duration was 4.81 years. As a result of factor analysis for developed stress coping questionnaire, four factors were extracted such as inactive, active, health and emotional behavior from 15 question items of stress coping questionnaire. Fifteen items passed for item internal consistency (100% success rate) and item discriminant validity (100% success rate). Cronbach's alpha coefficient for each factor ranged from 0.56 to 0.77. The active behavior correlated positively with job demand of JCQ (r=0.12, p<0.05), but total GHQ-28 was negatively correlation (r=-0.24, p<0.01), respectively. Conclusion: These results demonstrated the reliability and validity of SCBMS. Thus, the results may prove to be a useful assessment tool in evaluating stress coping behavior.

This study was done to develop a eating behavior scale for high school girls using Stunkard and Messick(1985)'s three factors(dietary restraint disinhibition, hunger) as a conceptual framework and to test the validity and reliability of the scale. The subjects were 202 high school girls. The convenience sample is consist of 96 normal weight and 106 obese girls. Data were collected between October 28 and November 25 in 1996 and analyzed using the SPSS package. The new 32-item scale measuring these factors is presented 1. Three stable factors emerged and these contributed 45.7% of the variance in the total score. All 32 items loaded above .35 on each factor, 2. Factor 1 was named disinhibition(14 items), factor 2 was named cognitive restraint of eating(10 items), factor 3 was named hunger(8 items). Comparison of factor Ⅰ, factor Ⅱ, factor Ⅲ between normal subjects and obese subjects showed that there was a significant difference in factor Ⅱ & Ⅲ, not in factor Ⅰ. 3. Cronbach's alpha coefficient for internal consistancy was .9393 for total 32 items and .8820, .8652, .8490 for three dimensions of eating behavior in high school girls. Recommendations are suggested below : 1. Replication study with appropriate age groups be done to test validity and reliability, 2. The present developed scale must be a reliable measure of eating behavior and should have utility in further study on how effective nursing intervention related to different kind of groups such as disinhibition group and cognitive restraint of eating group. 3. To extend validity of the scale, further study is needs using more larger subjects which is consists of dieters and free eaters.

Purpose: This study aimed to develop the Korean Prototype of Wellness Index (KP-WI) and identify the relationship between Koreans' health characteristics and wellness. Methods: The Wellness Index (WI) was translated into the primitive version of the KP-WI, considering the Koreans' culture and health behavior. It was administered to 223 service industrial employees at one workplace along with the Positive Affect and Negative Affect Schedule (PANAS) and Stress Questionnaire-Short Form. Data analyses included item-total correlation, Pearson's correlation coefficient, independent t-test, and one-way ANOVA. Results: The primitive version was modified to KP-WI based on the item-total correlation. The items considered to lower the reliability of the KP-WI were eliminated. Cronbach's ${\alpha}$ for each subscale ranged from .857 to .939. Perceived stress and negative emotions correlated significantly with wellness measured by KP-WI (r=-.29, p<.001; r=-.27, p<.001). Positive emotions correlated significantly with wellness (r=.60, p<.001). Conclusion: This study contributes to the development of Korean-style wellness indexes by developing a prototype and exploring the factors related to wellness.

연구배경: 만성폐질환 환자에서 삶의 질을 측정하는 도구로서 세인트조지 호흡기 설문(St George's Respiratory Questionnaire;SGRQ)이 개발되어 치료효과를 판정하는 측정지표로 널리 사용되고 있으나 영어권국가에서 만들어 졌기 때문에 우리나라에서 동일하게 사용하는데 제한점을 가지고 있다. 따라서 이의 정확한 적용을 위해서 언어, 기술, 개념적인 관점을 고려하여 한국어 설문지를 만들고 이들의 타당도와 신뢰도를 평가하였다. 방 법: 한국판 세인트조지 호흡기 설문은 번역, 역번역, 전문가 패널의 수정을 통해 완성되었고, 세브란스병원 호흡기내과를 방문한 환자를 대상으로 하여 이 설문을 시행하였다. 신뢰도 검정은 Cronbach's $\alpha$를 구하여 측정하였고 타당도는 폐기능검사, 6분보행검사, 호흡곤란지수와 산소포화도 검사를 동시에 시행하여 설문 검사결과와의 상관관계를 알아보았다. 결 과: 74명의 환자를 대상으로 시행하였으며, 남녀 비는 2.2:1, 평균연령은 $63.8{\pm}10.3$세였다. 이 중 천식환자는 27명(36.5%), 만성폐쇄성폐질환 환자는 39명 (52.7%)이었고, 결핵에 의한 파괴 폐환자는 8명(10.8%)이었다. Cronbach's ${\alpha}$ 값은 증상영역, 활동영역, 영향영역 및 총 점수에서 각각 0.63, 0.87, 0.89, 0.92 이였다. 총점수와 $FEV_1$, FVC, 6분보행거리, 산소포화도, 호흡곤란지수와 유의한 상관관계를 보였다. 결 론: 한국어판 세인트조지 호흡기 설문은 만성폐질환 및 천식과 같은 만성폐질환 환자에서 신뢰도가 높았고 총점수와의 상관관계는 6분보행검사 및 산소포화도에서 높음을 알수 있었고 폐기능 검사와의 상관계수는 원저인 세인트조지 호흡기설문 및 타 국가의 번역본 호흡기설문에서와 같이 높지 않음을 알 수 있었다. 따라서 우리나라에서도 호흡기질환의 삶의 질에 대한 치료효과 판정에 활용할 수 있을 것으로 기대된다.
