SBAR II: Application of SBAR

SBAR II: Application of SBAR

Assessment of Ventilation II: Respiratory Depth and Rhythm

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Clinical Psychology

Background:

Acceptance and mindfulness are increasingly central to behavioral and cognitive therapies.
Acceptance and Commitment Therapy (ACT) is a prominent approach, showing promise for psychosis.
A lack of acceptance-based measures for psychotic symptoms hinders research into therapy mechanisms.

Purpose of the Study:

To describe the preliminary evaluation of a new self-report instrument.
To assess acceptance-based attitudes and actions related to auditory and command hallucinations.
To develop a measure for investigating ACT mechanisms in psychosis.

Main Methods:

Initial scale development of the Voices Acceptance and Action Scale (VAAS).
Administration of a 56-item VAAS to 43 participants with command hallucinations.
Reliability and construct validity analyses, including correlations with depression, quality of life, and coping strategies.

Main Results:

A 31-item version of the VAAS was retained after reliability testing.
The 31-item VAAS demonstrated acceptable internal consistency and test-retest reliability.
The VAAS showed significant correlations with depression, quality of life, and coping, and discriminated compliance with harmful commands.

Conclusions:

The preliminary findings suggest the VAAS is a promising tool.
The VAAS may aid in assessing the psychological impact of auditory hallucinations.
Further research is needed due to the preliminary nature and limitations of the study.
