Summary. Background: This article provides an overview of studies in which assessments of specific functional capacity, made by experts on the one hand (objective) and by patients on the other (subjective) were compared in various patient groups. In essence, these data reveal marginal or insignificant associations.
Methods: Based on these considerations, a theoretical differential-diagnosis model of objective findings/subjective state of health is presented. By dichotomization of specific functional capacity at these two levels, the model permits the classification of a patient cohort into four sub-groups: Patients with concurrence between subjective and objective assessments are referred to as “the fortunate” while those with a negative concurrence are termed “the unfortunate”. In case of discrepancies between these two levels, for instance when patients’ subjective assessment was good although their condition was obviously poor, they are considered to be in a so-called “disease paradox”. Alternatively, patients whose subjective assessment of their condition was poor although the objective findings were positive, were considered to be in a so-called “health dilemma”.
Results: The study in a sample of patients who had received an artificial hip joint for mobility disorders revealed striking differences in health-related quality of life (HrQol). Comparisons of HrQoL data pre- and post-operatively in the whole sample demonstrated an improvement in five of six dimensions (loss of energy, pain, emotional reaction, sleeping problems, and problems in physical mobility, p<0.01) of the Nottingham Health Profile. Specifically, after grouping patients accordingly to the proposed model striking positive changes in HrQoL were registered in patients of the fortunate and disease paradox groups while the improvements in the health dilemma and unfortunate groups were minimal.
Conclusion: Timely identification of these patients in the process of rehabilitation would significantly contribute to the achievement of a good health-related quality of life for all patients.

Objectives and Research Themes
This work aims to evaluate how discrepancies between objective medical assessments and patients' subjective health evaluations impact health-related quality of life (HrQoL) during the rehabilitation process, specifically within an orthopedic cohort.
- Analysis of congruence and discrepancy between expert and patient health assessments.
- Theoretical development of the "Viennese model" for differential diagnosis in rehabilitation.
- Empirical testing of HrQoL outcomes in post-surgical hip arthroplasty patients.
- Investigation of inner "health resources" and their role in subjective health perception.
- Need-oriented application of future rehabilitation services based on patient classification.
Excerpt from the Book
Pilot study: Patients, Material, and Methods
Orthopedic patients are very suitable for the implementation and empirical testing of the said pre-conditions, particularly because appropriate survey instruments are either available or being used in a standardized manner in this specialty. In the following investigation, which was conducted in cooperation with the Orthopedic Hospital Speising in Vienna, the Harris Hip Score (Harris, 1969) was used as the objective instrument to measure the specific functional capacity of orthopedic patients while the Hannover Functional Questionnaire (Kohlmann & Raspe, 1996; Kohlmann et al., 1999) was employed as the subjective instrument. The first is a classification instrument used by orthopedists to assess the success of hip surgery. Four different dimensions evaluate the patient’s current functional capacity as assessed by the orthopedist: mobility, functional activity, pain and deformity. The sum of the four weighted scores is used to assign the patient to one of four categories on a scale from 0 to 100 (very good: 90–100, good: 80–90, moderate: 70–80 and poor: less than 70). The questionnaire to survey subjective functional capacity contains 18 items with which the patient assesses his/her impairment of motor activities in daily life in a three-categorical format (“yes”, “yes but with difficulty”, “no”; a copy of the questionnaire can be found in Knahr, Kryspin-Exner, Jagsch, Freilinger & Kasparek, 1998, page 325). Low scores indicate good functional capacity. Thus, the two instruments to assess specific function are poled in opposite directions.
Summary of Chapters
Introduction: This chapter reviews theoretical classifications of illness behavior and subjective-objective discrepancies in quality of life research as established by previous researchers.
Discrepancies between objective findings and subjective state of health in the health sector: This section details empirical evidence showing that medical clinical findings and patient self-assessments often correlate weakly.
Explanation of terms: This chapter clarifies key definitions, specifically differentiating between general and specific functional capacity, and establishes the construct of health-related quality of life.
Model to study Objective findings/Subjective state of health: This section presents the modified Viennese model used to categorize patients based on concurrent or discrepant health assessments.
Pilot study: Patients, Material, and Methods: This chapter describes the empirical methodology, the patient sample (n=101), and the specific survey instruments applied in the study.
Results: This chapter presents data analysis showing significant HrQoL improvements for specific patient subgroups while identifying minimal progress for others.
Discussion: This chapter synthesizes findings to recommend a more targeted, need-oriented approach to allocating rehabilitation resources based on the patient's subjective-objective health profile.

Frequently Asked Questions
What is the primary focus of this study?
The study focuses on the intersection of medical expert judgment and patient self-assessment regarding health, specifically examining how differences between these two perspectives affect the outcomes of rehabilitation.
What are the central themes discussed in the work?
The central themes include the discrepancy between objective and subjective health findings, the theoretical classification of patient groups into categories like "fortunate" or "disease paradox," and the measurement of quality of life in post-surgical patients.
What is the core research goal?
The primary goal is to determine if categorizing patients based on their level of agreement between objective clinical findings and subjective health reports can help predict and improve health-related quality of life outcomes in rehabilitation.
Which scientific methodology is utilized?
The study employs a theoretical model (modified Viennese model) to classify patients, combined with a quantitative empirical analysis using standardized orthopedic survey instruments like the Harris Hip Score and the Nottingham Health Profile.
What topics are covered in the main body?
The main body covers a literature review on illness behavior, a detailed explanation of constructs like "specific functional capacity," the presentation of the study model, the methodology of a hip surgery pilot study, and a comprehensive analysis of the resulting patient data.
How would you characterize this work through keywords?
The work is characterized by terms such as health-related quality of life, functional capacity, rehabilitation, subjective versus objective assessments, and total hip arthroplasty.
What defines a patient in the "disease paradox" category?
A "disease paradox" patient is someone whose objective medical findings are poor, but who maintains a positive subjective assessment of their own state of health.
What does the study suggest for clinical practice?
The study suggests that rehabilitation resources should not be distributed equally to all patients but should be specifically focused on those who struggle, such as the "unfortunate" and "health dilemma" groups, to optimize quality of life.
