Purpose: The purpose of this study was to develop a meaning of life scale with high validity and reliability. Method: A conceptual framework composed of 4 phases of meanings of life was identified. And 49 preliminary items on a 4-points scale were developed through content validity. A reliability and validity test of the 49 items was conducted on 564 adults. By means of internal consistency of the 49 items, 1 item was deleted. To verify the 48 items, factor analysis, reliability test, and LISEREL were done. Result: Through exploratory factor analysis of the 48 items, 8 factors were extracted. These factors were labeled as 'self- awareness and self-acceptance', 'hope', 'responsibility awareness', 'love experience', 'self transcendence', 'relation experience', 'self contentedness', and 'Commitment'. Through LISEREL of the 48 items, 2 items were excluded and finally 46 itemsremained. Cronbach's Alpha of the 46 items was .94. The correlation coefficient of the Self-esteem scale was .79. Conclusion: By the above results, the researchers recommend the following: An exploratory study on the variables related to the meaning of life are needed for criterion validity of this scale. Studies on meaning of life of different groupa, and subjects are needed for reverification.

Purpose: The purpose of this study was to test the reliability and validity of an MIL instrument for adolescents. Method: The research design was a three-phase, methodological study. 1) The original 46 items of the Meaning in Life (MIL) Scale were reviewed and corrected partially by 20 adolescents. 2) The content was validated by an expert panel (n=15) and adolescents (n=5). 3) The instrument was validated by survey (n=468). Finally, 33 items were chosen for the adolescents meaning in life(AMIL) scale. Results: Cronbach's alpha coefficient of the 33 items was .92, confirming the high internal consistency of the instrument. 2) Eight factors were extracted through factor analysis: 'experience of love', 'making efforts for goal', 'awareness of essential being', 'awareness of self limitation', 'feeling of satisfaction', 'relation experience', 'positive thinking', and 'hope'. These factors explained 58.26% of the total variance. Conclusion: AMIL Scale was identified as a tool with a high degree of reliability and validity. The tool can therefore be effectively utilized to assess the degree of meaning of life in caring areas for adolescents. Studies on AMIL of different adolescent subjects are needed for further verification.

It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

Purpose: This study was done to verify the self-directed learning instrument (SDLI) developed to measure self-directed learning ability in nursing students. Methods: The participants for the study were 425 nursing college students. Their self-directed learning was verified using self-reports and results through questionnaires. SDLI was translated into Korean through translation/reverse translation process and its content validity verified by five experts. The validity of the instrument was verified through item analysis, exploratory factor analysis, and confirmatory factor analysis. Reliability verification was analyzed using internal consistency reliability. Results: Four factors were identified through exploratory factor analysis and 20 items of the original instrument were found to be valid. In the confirmatory factor analysis, the validity of the instrument was verified as the model was valid. The internal consistency reliability was also acceptable and SDLI was found to be an applicable instrument. Conclusion: SDLI has been developed and verified by selecting nursing students as participants for the study. Use if SDLI is expected to improve the quality of self-directed learning in nursing education and to be used in future nursing research.
