Constructing validity: New developments in creating objective measuring instruments.

Constructing Validity: Basic Issues in Objective Scale Development

A primary goal of scale development is to create a valid measure of an underlying construct. We discuss theoretical principles, practical issues, and pragmatic decisions to help developers maximize the construct validity of scales and subscales. First, it is essential to begin with a clear conceptualization of the target construct. Moreover, the content of the initial item pool should be overin...

Developments of the new instruments for TMJ arthroscopic surgery.

A large and clearly visible operating area is essential for successful arthroscopic surgery of the temporomandibular joint. The keys to a successful operation are the safe and accurate positioning of a large scope and multiple cannulations, overcoming blind areas. We developed some instruments to resolve these problems; i.e., scopes with a large diameter for high resolution, a triangulation ins...

A New Algorithm for Constructing the Pareto Front of Bi-objective Optimization Problems

Here, scalarization techniques for multi-objective optimization problems are addressed. A new scalarization approach, called unified Pascoletti-Serafini approach, is utilized and a new algorithm to construct the Pareto front of a given bi-objective optimization problem is formulated. It is shown that we can restrict the parameters of the scalarized problem. The computed efficient points provide...

Gender Differences in Validity Scales of Personality Measuring Instruments in Psychiatric Patients.

The main goal of the study was to determine gender differences in validity scales of personality measuring instruments, among the psychiatric patients. Additional goals are to find the differences among male and female psychiatric patients, in relation to their age group, education level and type of psychiatric diagnosis. A total of 331 male and 331 female participants (psychiatric patients) ar...
