Questionnaire-Description

The Patient Pain Questionnaire (PPQ-16) is an assessment tool designed to measure pain from the patient’s perspective. It consists of 16 questions focusing on the intensity, distribution, quality, and impact of pain on the individual’s daily life. The PPQ-16 was developed to capture the subjective experience of pain and to support the diagnosis and monitoring of therapeutic approaches.

Data Analysis and Usage

Analyzing data from the PPQ-16 involves evaluating responses to the 16 questions using a rating scale, typically from 0 (no pain) to 10 (extreme pain). The collected data provides information on the intensity, duration, frequency, and impact of pain on the patient’s quality of life.
Key Analysis Methods:
Descriptive Statistics: Calculation of means, variances, and other statistical measures to understand the general level of pain.
Factor Analysis: Analysis of the structure of the questions to identify different dimensions of pain (e.g., physical pain, psychological impact).
Correlation and Analysis of Variance (ANOVA): Examination of differences in pain between different groups or conditions.
Evaluation may also include comparisons with other pain scales or general quality of life measures to validate the tool’s accuracy and reliability.

Purpose

The primary goal of the PPQ-16 is to provide a detailed and accurate method for assessing the subjective experience of pain from the patient’s perspective. The scale is designed to record the intensity, duration, and impact of pain on daily life, to aid in diagnosis and pain management, and to support treatment.

Calibration

Calibration of the PPQ-16 involves validating the scale through research assessing its reliability and validity. Key steps include:
Reliability: Calculating Cronbach’s alpha for internal consistency and analyzing the stability of measurements through test-retest reliability.
Validity: Examining convergent and divergent validity through comparisons with other relevant pain scales and quality of life measures.
Calibration may also include studying the scale’s sensitivity to changes in pain related to therapeutic interventions.
