Article Synopsis
  • The scoping review investigates the role and contribution of qualitative research in understanding response shift, a concept related to how individuals perceive changes in their health-related quality of life over time.
  • A total of 50 articles were examined, with 39 retained; most studies scored highly on appraisal criteria and explored diverse patient populations, including patients, caregivers, and healthcare professionals.
  • Findings suggest that qualitative methods provide in-depth insights into the cognitive and emotional aspects of quality-of-life assessments, offering valuable theoretical and methodological contributions that enhance the understanding of response shift beyond what quantitative studies typically capture.*

Background: With the increased use of patient-reported outcomes measures (PROMs) to assess spine surgery outcomes, it is important to understand how patients interpret their health changes over time. The measurement of cognitive-appraisal processes enables the quantification of how individuals think about quality of life (QOL). This study examined how appraisal processes were associated with patients' views of their role in managing their health-patient activation.

Background: People who were disabled from working reported substantially worse depression in recent research [1] despite adjustment for demographic covariates, cognitive-appraisal processes, and COVID-specific stressors, thus motivating the present work.

Objective: This study sought to "drill down" to understand employment-group differences (employed, retired, unemployed, disabled) in cognitive factors, and how these factors played into paths to depression during COVID early in the pandemic and depression trajectories over 15.5 months of follow-up.

Purpose: The present study examines how the coronavirus disease 2019 (COVID-19) experience affected values and priorities.

Methods: This cross-sectional study collected data between January and April 2023, from 1,197 individuals who are chronically ill or part of a general population sample. Using open-ended prompts and closed-ended questions, we investigated individuals' perceptions about COVID-19-induced changes in what quality of life means to them, what and who are important, life focus, and changes in norms and stressors.

This paper proposes a new model of stress that integrates earlier models and adds insights from developmental psychology. Previous models describe the behavioral and physical effects of stress events, but have not explained the translation of experiences into stress itself. The Developmental Model of Stress shows how psychosocial developmental challenges in childhood create persistent negative beliefs and behaviors that increase threat perception and maladaptive stress responses.

A common symptom of paroxysmal nocturnal hemoglobinuria (PNH) is fatigue, which in some patients can be severe. Eculizumab (Ecu) has proven efficacy in controlling intravascular hemolysis, but commonly results in persistent anemia and fatigue. Pegcetacoplan's (Peg) efficacy was documented in the PEGASUS phase III clinical trial, showing improved hemoglobin (Hb) and patient-reported fatigue.

Spine surgery generally yields a notable improvement in patients' health state, and there is variability in measured patient outcomes after spine surgery. The present work aimed to describe for clinicians how appraisal underlies their patients' experience of healthcare interventions. This prospective longitudinal cohort study (n = 156) included adults undergoing spine surgery for degenerative spinal conditions.

Background: Hemorrhoid disease (HD) affects 10 million people in the US at any given time, and 50% of the US population will develop symptomatic hemorrhoids during their lifetime. Approximately 60% of people with hemorrhoids experience symptoms. Despite its prevalence and impact on quality of life, the existing patient-reported outcome measures of HD have not been validated using standard psychometric methods.

Background Context: A not uncommon finding following spine surgery is that many patients do not achieve mental health improvement up to population norms for their age cohort, despite improvement in pain and functioning.

Purpose: This study examined how patients who were categorized as depressed versus not depressed think about health-related quality of life as assessed by cognitive-appraisal processes. It examined cross-sectional and longitudinal differences over 12 months postsurgery.

Article Synopsis
  • - This paper questions the belief that item-response theory (IRT) always provides a better measurement for clinical constructs, highlighting potential drawbacks in content loss that may affect conceptual validity.
  • - Two studies are summarized that demonstrate how IRT analyses overlooked essential aspects of the conceptual models used in quality of life (QOL) measurement.
  • - The findings suggest that effective measurement should combine the quantitative benefits of IRT with a recognition of the significance of conceptual validity and practical clinical application.

Purpose: Understanding people's response to the pandemic needs to consider individual differences in priorities and concerns. The present study sought to understand how individual differences in cognitive-appraisal processes might moderate the impact of three COVID-specific factors-hardship, worry, and social support-on reported depression.

Methods: This longitudinal study of the psychosocial impact of the COVID-19 pandemic included 771 people with data at three timepoints over 15.

Background: The present study sought to investigate how comorbidity burden influences cancer survivors' quality of life (QoL) and the challenges/adaptations during the coronavirus disease 2019 (COVID) pandemic, and to examine how appraisal processes are related to this impact.

Methods: This cross-sectional study, administered in spring/summer 2020, compared cancer survivors to a general-population comparison sample. QoL was assessed with standardized tools.

Background: Treatment-related late effects can worsen over time among cancer survivors. Such worsening health states may trigger changes in internal standards, values, or conceptualization of quality-of-life (QOL). This "response-shift" phenomenon can jeopardize the validity of QOL assessment, and misrepresent QOL comparisons over time.

Background: The impact of the coronavirus disease 2019 (COVID) is worse among those with fewer financial resources, in jobs not amenable to remote work, and in denser living conditions. People of color are more likely to be among these vulnerable groups. Although race itself is a social construction and not based on underlying genetic/biological differences, this study investigated race/ethnicity differences in the negative repercussions of COVID and in the benefits of psychological and social resources.

Background: While a substantial body of work postulates that adaptation (response-shift effects) may serve to hide intervention benefits, much of the research was conducted in observational studies, not randomized-controlled trials. This scoping review identified all clinical trials that addressed response shift phenomena, and characterized how response-shift effects impacted trial findings.

Methods: A scoping review was done of the medical literature from 1968 to 2021 using as keywords "response shift" and "clinical trial.
