Questionnaire-Description

The Problem Checklist (PC-154) is a questionnaire consisting of 154 items (questions) that covers a broad range of issues that an individual may encounter. These problems may relate to various aspects of life, such as:

Physical health

Emotional and psychological state

Interpersonal relationships

Financial and professional difficulties

Personal habits and behaviors

The checklist is designed to help therapists and researchers identify problematic areas that may require intervention or further investigation. Participants are asked to rate the extent to which each item represents a problem for them.

Data Analysis and Usage

Data from the PC-154 are collected through self-reports, where participants respond to each question based on their experiences. The responses are typically evaluated using a Likert scale, where participants rate the severity or frequency of each problem.

Analytical techniques used include:

Factor analysis to identify the main categories of problems and their dimensions.

Reliability analysis, such as calculating Cronbach’s alpha, to measure the internal consistency of the scale.

Descriptive statistics to determine the prevalence and severity of problems among participants.

The data can be used for developing appropriate interventions, designing therapeutic programs, and evaluating changes in an individual’s condition following therapeutic intervention.

Purpose

The goal of the Problem Checklist (PC-154) is to provide a comprehensive overview of the problems that an individual faces. Specifically, the checklist aims to:

Identify problematic areas in an individual’s life that may require psychological or social intervention.

Monitor the progression of an individual’s condition over time, particularly in the context of therapy or counseling.

Provide a diagnostic tool that can guide therapists and researchers in better understanding and addressing the difficulties individuals face.

Calibration

The calibration of the PC-154 includes:

Reliability analysis to estimate the internal consistency and stability of the scale.

Factor analysis to identify the thematic areas or dimensions covered by the questionnaire, ensuring that the scale represents the problems it aims to measure.

Validation of the scale through studies in different populations to ensure that the scale can be used reliably in various settings and with different groups of individuals.
