Summary
The Japanese version of the INTERMED screening tool demonstrates high reliability and consistency for assessing patients. This tool is useful for proactive biopsychosocial care in Japan.
Area of Science:
- Psychiatry
- Health Services Research
Background:
- The INTERMED is a tool for assessing biopsychosocial needs.
- Its utility in Japan requires validation.
Purpose of the Study:
- To establish the inter-rater reliability and internal consistency of the Japanese version of the INTERMED.
- To assess the utility of the INTERMED in the Japanese healthcare context.
Main Methods:
- Patients from psychiatric and palliative care services were independently scored using the INTERMED by raters.
- Statistical analyses included intraclass correlation coefficient and Cronbach's alpha.
Main Results:
- The Japanese INTERMED showed high inter-rater reliability (ICC=0.98) and internal consistency (α=0.89).
- All four domains (biological, psychological, social, healthcare) were positively correlated.
- A cutoff score of 20/21 yielded a kappa coefficient of 0.79.
Conclusions:
- The INTERMED-Japanese version is a reliable and consistent tool for biopsychosocial screening.
- It is a useful and practical tool for the current Japanese healthcare system.
- Further research should explore its utility in improving care for patients with complex needs across various Japanese medical settings.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:20Kendall's Coefficient of Concordance
Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects or...
02:20Correlations
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
01:20Spearman's Rank Correlation Test
Spearman's rank correlation test, also known as Spearman's rho, is a nonparametric method for assessing the strength and direction of association between two variables. This test is particularly valuable when the data distribution is unknown or when the assumption of normality does not hold. Named after the English psychologist and statistician Dr. Charles Edward Spearman, it serves as the nonparametric counterpart to Pearson's correlation coefficient.

01:29Self-Evaluation Maintenance Model
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
01:24Confidence Coefficient
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under both the...
