Reliability and Validity of the Brief Schema Questionnaire for Adult / 신경정신의학

OBJECTIVES: The aim of this study was to develop a brief schema questionnaire for adults (BSQ-A) and investigate its validity and reliability. METHODS: A 36-item questionnaire was developed or selected by six psychiatrists. The questionnaire was administered to 209 subjects in Seoul and Gyeonggi area. The construct validity was investigated by performing principal component analysis, and the reliability was assessed in terms of the internal consistency using Cronbach's alpha. RESULTS: The principal component analysis revealed 18 factors underlying 18 early maladaptive schemas (EMSs). These 18 factors accounted for 87.488% of the common variance. The Cronbach's alpha was high, indicating that the reliability of the questionnaire was satisfactory. Every schema showed a positive correlation with most psychological measures. CONCLUSION: The results indicate that the BSQ-A is a reliable and valid scale for assessing EMSs. Although there are many limitations, the present study is expected to form the basis of future research.

Reliability and Validity of the Mental Health Questionnaire for Adult / 신경정신의학

OBJECTIVES: The aim of this study was to develop a Mental Health Questionnaire for Adults (MHQ-A) and investigate its validity and reliability. METHODS: A 73-item questionnaire was developed or selected by seven psychiatrists and a clinical psychologist. The questionnaire was administered to 351 subjects in Seoul and Gyeonggi area. The construct validity was investigated by performing principal component analysis, and the reliability was assessed in terms of the internal consistency using Cronbach's alpha. RESULTS: Principal component analysis revealed 15 factors underlying the psychiatric disorder and symptom category. Taken together, these 15 factors accounted for 64.023% of the common variance. Cronbach's alpha was high, indicating that the reliability of the questionnaire was satisfactory. Every category showed a positive correlation with most psychological measures. CONCLUSION: These results indicate that the MHQ-A is a reliable and valid scale for assessing psychiatric disorders. Although there were many limitations, the present study has significance as the basis of future research.

Effects of Nursing Interventions Applied to Surgery Patients: A Meta-analysis / 성인간호학회지

A meta-analysis of 13 quasi-experimental studies was conducted to determine the effect of various nursing interventions applied to surgery patients. The studies were selected from dissertations done between 1982 to 1996 and had randomized or nonequivalent control groups in a pretest-post test design. The studies were classified according to three criteria : 1) types of surgery 2) types of nursing interventions 3) types of respondent variables. The following analysis was done : 1) Determination of usefulness of nursing interventions for surgery patients. 2) The magnitude of effect for each study was tested for different types of surgery, nursing interventions and outcome variables. 3) For a group of homogenious studies, the weighted mean effect size and standard error were estimated. Some findings are summarized as follows : Nursing interventions on relaxation effect applied to surgery patients have resulted in a significant effect size on pain, anxiety, and BP stabilization. Relaxation and music therapy were more effective on surgery patients than either education, heat therapy, or purposeful touch. It was impossible to identify which type of surgery was more effected by these interventions. On the basis of these findings, the following recommendations were made : 1) Many studies on the same kind of intervention applied to similar surgery patients should be accumulated continuously to identify factors that affect the effect size. 2) The detailed explanation of research process, such as, assignment method to experimental and control groups, starting points, duration and frequency of nursing interventions, and estimation of the outcome variables should be described in orther to be utilized for further research and practice.
