What Do You Think You Are Measuring? A Mixed-Methods Procedure for Assessing the Content Validity of Test Items and Theory-Based Scaling
The valid measurement of latent constructs is crucial for psychological research. Here, we present a mixed-methods procedure for improving the precision of construct definitions, determining the content validity of items, evaluating the representativeness of items for the target construct, generating test items, and analyzing items on a theoretical basis. To illustrate the mixed-methods content-scaling-structure (CSS) procedure, we analyze the Adult Self-Transcendence Inventory, a self-report measure of wisdom (ASTI, Levenson et al., 2005). A content-validity analysis of the ASTI items was used as the basis of psychometric analyses using multidimensional item response models (N = 1215). We found that the new procedure produced important suggestions concerning five subdimensions of the ASTI that were not identifiable using exploratory methods. The study shows that the application of the suggested procedure leads to a deeper understanding of latent constructs. It also demonstrates the advantages of theory-based item analysis.
Empathy: Assessment Instruments and Psychometric Quality – A Systematic Literature Review With a Meta-Analysis of the Past Ten Years
Objective: To verify the psychometric qualities and adequacy of the instruments available in the literature from 2009 to 2019 to assess empathy in the general population.Methods: The following databases were searched: PubMed, PsycInfo, Web of Science, Scielo, and LILACS using the keywords “empathy” AND “valid∗” OR “reliability” OR “psychometr∗.” A qualitative synthesis was performed with the findings, and meta-analytic measures were used for reliability and convergent validity.Results: Fifty studies were assessed, which comprised 23 assessment instruments. Of these, 13 proposed new instruments, 18 investigated the psychometric properties of instruments previously developed, and 19 reported cross-cultural adaptations. The Empathy Quotient, Interpersonal Reactivity Index, and Questionnaire of Cognitive and Affective Empathy were the instruments most frequently addressed. They presented good meta-analytic indicators of internal consistency [reliability, generalization meta-analyses (Cronbach’s alpha): 0.61 to 0.86], but weak evidence of validity [weak structural validity; low to moderate convergent validity (0.27 to 0.45)]. Few studies analyzed standardization, prediction, or responsiveness for the new and old instruments. The new instruments proposed few innovations, and their psychometric properties did not improve. In general, cross-cultural studies reported adequate adaptation processes and equivalent psychometric indicators, though there was a lack of studies addressing ...
Psychometric properties of self-reported measures of health-related quality of life in people living with HIV: a systematic review - Health and Quality of Life Outcomes
Objective To identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of health-related quality of life (HRQoL) in people living with HIV (PLWH). Methods Nine databases were searched from January 1996 to October 2020. Methodological quality was assessed by using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias Checklist. We used the COSMIN criteria to summarize and rate the psychometric properties of each PROM. A modified Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of evidence. Results Sixty-nine studies reported on the psychometric properties of 30 identified instruments. All studies were considered to have adequate methodological quality in terms of content validity, construct validity, and internal consistency. Limited information was retrieved on cross-cultural validity, criterion validity, reliability, hypothesis testing, and responsiveness. High-quality evidence on psychometric properties was provided for the Medical Outcomes Study HIV Health Survey (MOS-HIV), the brief version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQoL-HIV-BREF), 36-Item Short Form Survey (SF-36), Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQoL-HIV), and WHOQoL-HIV. Conclusions The findings from the included studies highlighted that among HIV-specific and generic HRQoL PROMs, MOS-HIV, WHOQoL-HIV-BREF, SF-36, MQoL-HIV, and WHOQoL-HIV are strongly recommended to evaluate HRQoL in PLWH in research and clinics based on the specific aims of assessments and the response burden for participants.
Tools for measuring client experiences and satisfaction with healthcare in low- and middle-income countries: a systematic review of measurement properties - BMC Health Services Research
Background Perspectives of patients as clients on healthcare offer unique insights into the process and outcomes of care and can facilitate improvements in the quality of services. Differences in the tools used to measure these perspectives often reflect differences in the conceptualization of quality of care and personal experiences. This systematic review assesses the validity and reliability of instruments measuring client experiences and satisfaction with healthcare in low- and middle-income countries (LMICs). Methods We performed a systematic search of studies published in PubMed, SCOPUS, and CINAHL. This review was reported according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Studies describing the development and psychometric properties of client experience and satisfaction with general health care were included in the review. Critical appraisal of study design was undertaken using the Appraisal tool for Cross-Sectional Studies (AXIS). The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist and Terwee’s criteria were used to appraise the psychometric properties of the included studies. A narrative synthesis approach was used in the interpretation of the findings. Results Of the 7470 records identified, 12 studies with 14 corresponding instruments met the inclusion criteria and were included in the final review. No study assessed all the psychometric properties highlighted by the COSMIN criteria. In most instruments, we found evidence that initial development work incorporated client participation. The most evaluated measurement properties were content validity, internal consistency, and structural validity. Measurement error and responsiveness were not reported in any study. Conclusion Reliability and validity should be considered important elements when choosing or developing an instrument for professionals seeking an effective instrument for use within the population. Our review identified limitations in the psychometric properties of patient experience and satisfaction instruments, and none met all methodological quality standards. Future studies should focus on further developing and testing available measures for their effectiveness in clinical practice. Furthermore, the development of new instruments should incorporate clients' views and be rigorously tested or validated in studies with high methodological quality. Trial registration CRD42020150438.

High risk of depression, anxiety, and poor quality of life among experienced fathers, but not mothers: A prospective longitudinal study - PubMed
In addition to maternal mental distress during the transition to parenthood, we highlighted experienced fathers' psychological difficulties throughout perinatal periods. Such trends may indicate unsatisfied needs and could guide timely intervention to prevent adverse consequences.
