Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
Self-Report Tests of Personality01:22

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.
Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Competing-Risk Nomogram for Predicting Cancer-Specific Survival in Multiple Primary Colorectal Cancer Patients after Surgery

Area of Science:

  • Psychology
  • Oncology
  • Family Studies

Background:

  • Parental cancer significantly impacts adult children.
  • Understanding this experience requires validated psychometric tools.
  • The Parental Cancer Questionnaire (PCQ) was developed to assess these impacts.

Purpose of the Study:

  • To determine the principal component structure of the PCQ.
  • To validate the reliability and subscale structure of the PCQ.
  • To assess the PCQ's utility in research on adult children of cancer patients.

Main Methods:

  • Administered the PCQ to 311 adult children of parents with cancer.
  • Utilized Exploratory Principal Components Analysis (PCA).
  • Assessed convergent and discriminant validity using related psychometric measures.

Main Results:

  • PCA identified three key dimensions: parental cancer benefits, emotional experiences, and caregiver strain, explaining 51% of the variance.
  • Convergent and discriminant validity were supported by significant correlations (0.14–0.68).
  • Internal reliability was strong, with Cronbach's alpha ranging from 0.87 to 0.91.

Conclusions:

  • The PCQ exhibits a clear three-component structure with robust reliability.
  • The questionnaire demonstrates excellent face, content, convergent, and discriminant validity.
  • The PCQ is a suitable and valuable measure for researching the parental cancer experience in adult children.
