The development of an MMPI alexithymia scale
Psychotherapy and Psychosomatics
|January 1, 1980
Summary
A new 22-item Minnesota Multiphasic Personality Inventory (MMPI) scale for alexithymia was developed. This scale accurately predicts alexithymia and demonstrates strong temporal stability for diverse populations.
Area of Science:
- Psychological assessment
- Psychosomatic medicine
Background:
- Alexithymia is a personality construct characterized by difficulty identifying and describing emotions.
- Existing assessment methods may lack efficiency or standardization across diverse populations.
Purpose of the Study:
- To develop and validate a new, brief scale for assessing alexithymia using the Minnesota Multiphasic Personality Inventory (MMPI).
- To evaluate the predictive accuracy and temporal stability of the novel MMPI alexithymia scale.
Main Methods:
- A 22-item MMPI scale was derived from the Beth Israel Psychosomatic Questionnaire (BIQ).
- The scale's predictive validity was assessed against BIQ alexithymia scores.
- Temporal stability was evaluated over time.
Main Results:
- The new MMPI alexithymia scale achieved an 82% hit rate in predicting BIQ alexithymia scores.
- The scale demonstrated impressive stability over time, indicating reliable measurement.
- The scale offers a rapid and standardized method for alexithymia assessment.
Conclusions:
- The developed 22-item MMPI scale provides a valid and reliable tool for assessing alexithymia.
- This new scale facilitates efficient and standardized alexithymia measurement in various populations.
- The MMPI-derived scale offers a practical approach for clinical and research settings.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

7.7K
Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

6.4K
The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
