Lazarus's Cognitive Appraisal Theory

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Summary

Systematic reviews (SRs) on aphasia treatment can lack quality. The Appraisal Tool to Assess Systematic Reviews 2 (AMSTAR 2) found two SRs had critically low methodological quality, advising clinicians to use quality assessment tools.

Area of Science:

Epidemiology
Clinical Research Methodology

Background:

Systematic reviews (SRs) synthesize research but quality varies.
Not all SRs meet established standards for conduct and reporting.
Assessing SR quality is crucial for reliable clinical application.

Approach:

This tutorial describes PRISMA 2020 for reporting and AMSTAR 2 for appraising SRs.
It compares items on PRISMA 2020 and AMSTAR 2 checklists.
AMSTAR 2 was used to critically appraise two SRs on aphasia treatment.

Key Points:

PRISMA 2020 guides SR preparation; AMSTAR 2 assesses SR quality.
AMSTAR 2 identified critical weaknesses in the methodological quality of both appraised SRs.
Both SRs, though thorough, received critically low overall confidence ratings.

Conclusions:

AMSTAR 2 is the preferred tool for examining SR quality.
Clinicians should use quality assessment tools like AMSTAR 2 to ensure SRs meet validity criteria.
This ensures findings from SRs can be confidently applied to patient care.
