이 연구의 목적은 최근 직무수행의 새로운 영역으로 주목받고 있는 맥락적 수행(contextual performance)이 사회복지 실천이론과 현장에서도 타당한 개념으로 인정받을 수 있는가를 검토하는 것이다. 이를 위해 본 연구에서는 현장의 관리자들을 대상으로 예비조사를 실시하여 연구실행의 가능성을 확인하였다. 이후 본 조사에서는 전국의 사회복지사 170명을 대상으로 맥락적 수행의 행동사례에 대한 질적 분석을 하였고, 질적분석 결과를 근거로 평가지표를 개발해 연구참여자를 대상으로 직무수행에 대한 상사 자기평가를 실시하였다. 이를 위해 다중속성-다중평정(multitriat-multimethod, MTMM) 자료를 구성하여 위계적 내재모형에 대한 확인적 요인분석을 실시하였다. 질적 양적 통합연구분석 결과, 사회복지사의 맥락적 수행의 영역은 '조직지향 수행', '동료지향 수행', '클라이언트지향수행', '자기지향 수행'의 4가지 영역으로 분류되었고, 이들은 기존의 직무수행과는 어느 정도 변별타 당도를 갖는 것으로 파악되었다. 본 연구에서는 이러한 연구결과에 근거하여 향후 사회복지사의 직무수행에 대한 연구전망과 제언을 제시하였다.

There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.

Purpose: This study evaluated the psychometric properties of the Korean version of Yale Food Addiction Scale for Children (YFAS-C). Methods: Participants were 419 young adolescent students (11~15 years old). The content validity of the expert group was calculated as the content validity index (CVI) after the translation and reverse translation process of the 25 items of the YFAS-C. The multitrait-multimethod matrix (MTMM) method was used to verify the construct validity; the generalized linear model (GLM) was used to evaluate the concurrent and incremental validity. Reliability was calculated as Kuder-Richardson-20 (KR-20) and Spearman-Brown coefficients. Results: The CVI of the 25 items was greater than the item-level CVI .80 and the scale-level CVI .90. The Korean version of YFAS-C had verified convergent validity in emotional eating and external eating and discriminant validity in restrained eating. In addition, it had verified concurrent validity in emotional eating and external eating. Finally the incremental validity of the Korean version of YFAS-C was statistically significant on BMI. Reliability was KR-20 ${\alpha}=.69$ and the Spearman-Brown coefficient was .64. Conclusion: The Korean version of YFAS-C is a valid and reliable scale for measuring the severity of food addiction; it can be a useful scale for preventing obesity by predicting food addiction early.
