Religiosity and spirituality are not single psychological variables. They can refer to participation in a religious community, private practice, the personal importance of faith, beliefs and meaning systems, ordinary spiritual experiences, religious coping, religious and spiritual struggles, or spiritual well-being. A research instrument therefore measures an operationally defined part of religious or spiritual life; it does not measure the truth, value, or authenticity of a person’s faith. Reviews of the field have repeatedly concluded that there is no single universally preferred measure and that interpretation depends on the construct, population, tradition, culture, language, and study purpose. Hall, Meador, & Koenig, 2008 APA Handbook of Psychology, Religion, and Spirituality, 2013
For a related perspective, see Psychology of Religion and Spirituality: Scope and Evidence.
For researchers, the central question is therefore not “Which scale measures religion?” but “Which construct do I need to measure, in whom, for what inference?” A five-item index of religious involvement can be excellent for a large epidemiological survey and inadequate for a study of spiritual struggle. A coping scale can be highly informative after bereavement or illness and still be the wrong tool for estimating the centrality of religion in personality. A spiritual well-being scale can capture meaning, peace, and faith while partly overlapping with the health outcome a study is trying to predict.
This guide explains the major research instruments most often encountered in psychology and health research, including the Duke University Religion Index (DUREL), the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS), the Centrality of Religiosity Scale (CRS), the Daily Spiritual Experience Scale (DSES), the Brief RCOPE, the Religious and Spiritual Struggles Scale (RSS) and RSS-5, the Spiritual Well-Being Scale (SWBS), and the FACIT-Sp-12. It also explains how to choose among them, how to interpret scores, and why reliability, validity, translation, cultural fit, and construct overlap must be evaluated in the population actually being studied.
What Does It Mean to Measure Religiosity or Spirituality?
Psychological measurement turns an abstract construct into observable responses. In religion and spirituality research, the construct may be behavioral, motivational, experiential, relational, cognitive, affective, or meaning-centered. Religious service attendance is behavior. Intrinsic religious commitment is motivation and salience. Religious coping describes ways of responding to stress. Spiritual struggle describes conflict, tension, doubt, moral distress, interpersonal strain, or difficulty around ultimate meaning. These domains can correlate, but they are not interchangeable.
The field’s classic multidimensional approach arose partly because global labels conceal these distinctions. The Fetzer Institute and National Institute on Aging working group organized religiousness/spirituality into multiple health-relevant domains and developed the Brief Multidimensional Measure of Religiousness/Spirituality for survey research. The resulting instrument was tested in the 1998 General Social Survey, where several dimensions showed moderate-to-good internal consistency while other domains were represented by single items. Fetzer Institute, Multidimensional Measurement of Religiousness/Spirituality Idler et al., 2003
This multidimensionality has a practical consequence: two people can have similar overall self-rated religiosity while differing substantially in public worship, private prayer, religious identity, doctrinal commitment, spiritual experience, coping, or struggle. A study that collapses these domains into one score may lose the mechanism it hoped to examine.
Religiosity, Spirituality, and Related Constructs Are Not the Same Variable
Religiosity usually refers to beliefs, practices, identities, commitments, experiences, and participation connected with a religious tradition or community. Spirituality is used more variably. Some instruments define it through transcendence or connection with the sacred; others emphasize meaning, peace, values, purpose, connectedness, or existential orientation. The names printed on scales do not guarantee that their items capture the same construct. A systematic classification of religion/spirituality instruments has shown that item content can diverge substantially from scale labels, which matters when researchers compare studies or pool effect sizes. Jeserich et al., 2023
For respectful research, measurement also requires theological and cultural humility. An instrument is a research model of selected psychological dimensions. It cannot determine whether a religious belief is true, whether a spiritual experience is genuine, whether a practice is spiritually valuable, or whether a person is “more authentic” in faith than another person. Those questions exceed what psychometric scores can establish.
Why a Single Global Religiosity Score Is Often Too Crude
A single self-rating such as “How religious are you?” can be useful when questionnaire space is extremely limited, but it sacrifices explanatory precision. Attendance may partly reflect community access, disability, caregiving, geography, minority status, or local custom. Prayer frequency may reflect devotion, coping with a crisis, communal practice, or a temporary life transition. Self-described spirituality may mean transcendence for one respondent and meaning, connectedness, or values for another.
A major review of religious measurement argued that “religiousness in general” is difficult to capture without context and warned against overgeneralizing from one dimension to the whole of religious life. The same review noted that many instruments were developed in predominantly American and Christian contexts, which places a burden on researchers to test whether wording, assumptions, and score interpretations transfer to other traditions and cultures. Hall, Meador, & Koenig, 2008
Major Research Instruments at a Glance
DUREL: a five-item index for organizational religious activity, non-organizational religious activity, and intrinsic religiosity; especially useful when survey space is limited.
BMMRS: a multidimensional survey framework for several domains of religiousness/spirituality in health research; useful when mechanism and domain coverage matter more than a single global score.
CRS: measures the centrality or salience of religious meanings through five core dimensions; available in several lengths and interreligious variants.
DSES: measures ordinary spiritual experiences in daily life rather than institutional participation or doctrine.
Brief RCOPE: a 14-item measure of positive and negative religious coping with major stressors; it is a coping instrument, not a global religiosity scale.
RSS / RSS-5: measures religious and spiritual struggles. The original RSS covers six struggle domains; the RSS-5 is a very brief five-item form developed for settings where burden matters.
SWBS: assesses religious and existential aspects of spiritual well-being. It is a well-being measure, so researchers studying mental health outcomes must consider conceptual overlap.
FACIT-Sp-12: assesses spiritual well-being through meaning, peace, and faith domains in health-related settings; it has a specific licensing and translation process.
Duke University Religion Index (DUREL)
The DUREL is a five-item measure developed for large observational and epidemiological studies. It assesses three dimensions: organizational religious activity, non-organizational religious activity, and intrinsic religiosity. Its brevity is its main advantage: it adds a multidimensional measure of religious involvement without consuming much survey space. Koenig & Büssing, 2010
The developers explicitly recommend analyzing the three dimensions as separate subscales when examining associations with health outcomes rather than treating all five items as one undifferentiated religiosity total. That recommendation reflects the conceptual difference between public participation, private activity, and internal religious commitment. Koenig & Büssing, 2010
DUREL is well suited to epidemiology, population health, and studies in which religious involvement is one predictor among many. It is less suitable when the central research question concerns spiritual experience, religious coping, doubt, struggle, religious identity development, or detailed denominational practice. Cross-cultural studies have produced useful validations, but a translation that is reliable in one population does not automatically establish measurement equivalence in another.
Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS)
The BMMRS emerged from the Fetzer Institute/National Institute on Aging initiative to improve measurement of religion and spirituality in health research. The broader project identified 12 domains and assembled a brief multidimensional survey from selected measures. It was designed to be brief enough for clinical and epidemiological research while retaining more domain coverage than a single religiosity index. Fetzer Institute, 2024 Idler et al., 2003
Its strength is breadth. Depending on the version and research design, investigators can examine dimensions such as daily spiritual experiences, values and beliefs, forgiveness, private religious practices, religious and spiritual coping, support, history, commitment, organizational religiousness, and self-ranking. This is useful when the study asks how different components of religious/spiritual life may relate to health through different pathways.
Its limitation is the same feature viewed from the opposite direction: BMMRS is not one narrow latent construct. Treating every domain as if it were a single interchangeable “religiosity score” defeats the purpose of a multidimensional instrument. Researchers should predefine which domains represent exposure, mediator, moderator, or outcome and report them transparently.
Centrality of Religiosity Scale (CRS)
The CRS measures how central, important, or salient religious meanings are within personality. Its core model includes five dimensions: intellectual engagement, ideology, public practice, private practice, and religious experience. Basic forms include CRS-5, CRS-10, and CRS-15; interreligious variants were developed to broaden applicability beyond strongly monotheistic wording. Huber & Huber, 2012
The shorter CRS-5 provides one indicator per core dimension, while longer versions provide more information within each domain. The original development paper reported internal-consistency evidence across multiple national samples and described adaptations for Buddhist, Hindu, and Muslim contexts. That does not mean a single English version is culturally universal. It means the scale was designed with cross-religious use in mind and offers documented variants that researchers should select deliberately rather than rewriting items ad hoc. Huber & Huber, 2012
CRS is particularly useful when the substantive question concerns the centrality of religion in a person’s system of meaning and action. It is not a measure of coping with a specific stressor, not a symptom scale, and not an assessment of spiritual well-being.
Daily Spiritual Experience Scale (DSES)
The DSES was developed to assess ordinary experiences of connection with the transcendent in daily life. The full instrument contains 16 items and was designed to capture experiences such as awe, gratitude, mercy, connection, compassionate love, and closeness to the divine or transcendent. Its original psychometric paper reported reliability, exploratory factor analyses, preliminary construct validity, and data from population samples. Underwood & Teresi, 2002 Underwood, 2011
DSES is appropriate when daily experience is the construct of interest. It should not be substituted for participation, doctrine, identity, or coping. The scale’s official resource recommends the full 16-item version and notes that the six-item version used in the General Social Survey was selected for survey economy rather than derived as an optimal psychometric short form.

Brief RCOPE: Measuring Religious Coping
The Brief RCOPE is a 14-item measure of religious coping with major life stressors, with seven positive religious coping items and seven negative religious coping items. It was designed as a shorter alternative to the much larger RCOPE and has become one of the most widely used instruments in the religious coping literature. Pargament, Feuille, & Burdzy, 2011
Positive and negative religious coping are distinct patterns rather than opposite ends of one continuum. Positive religious coping generally reflects strategies involving spiritual connection, benevolent religious reframing, or collaborative coping. Negative religious coping reflects religious/spiritual tension or strain. The labels describe coping patterns within the instrument; they do not declare a person’s faith healthy or unhealthy, nor do they define religious orthodoxy.
A 2024 review of Brief RCOPE studies outside the United States found substantial evidence supporting use across diverse cultures and populations while also emphasizing the need for more work in underrepresented religious traditions, cultural groups, and minority populations. Saunders & Stephenson, 2024
More recent evidence continues to show that validity is population-specific. In 2026, a study of 1,290 adults receiving residential treatment for substance use disorder supported the two-factor structure and reported measurement invariance across biological sex and across treatment time in that sample. That finding strengthens evidence for this clinical population but should not be generalized to every population or tradition without further validation. Manzler et al., 2026
Religious and Spiritual Struggles Scale (RSS) and RSS-5
The original Religious and Spiritual Struggles Scale is a 26-item measure developed to assess six domains of struggle: divine, demonic, interpersonal, moral, doubt, and ultimate meaning struggles. Its initial validation used multiple samples and supported a six-factor structure with evidence of convergent, discriminant, and predictive validity. Exline et al., 2014
The construct is psychologically important because struggle can occur within committed religious life, during spiritual change, amid illness or loss, or in conflict with communities, beliefs, moral commitments, or questions of meaning. A high score describes greater endorsement of the measured struggle content. It does not diagnose a mental disorder, determine whether a belief is irrational, or establish that religious involvement itself is harmful.
The RSS-5 is a five-item short form published in 2025. It was developed across samples that included adults with depression from prior studies, university students, and adults seeking psychotherapy and/or primary care. The five-item version represented divine, interpersonal, moral, doubt, and ultimate meaning struggles and showed internal consistency estimates from .77 to .85 across the three studies. Its brevity makes it attractive for screening research burden, but it necessarily contains less domain-specific information than the 26-item RSS. Salcone et al., 2025
Neither the RSS nor RSS-5 should be used as a stand-alone psychiatric diagnostic instrument. Religious or spiritual struggle may coexist with depression, anxiety, obsessive-compulsive symptoms, trauma, grief, or no clinical disorder at all. Clinical interpretation requires context, duration, severity, functional impact, the person’s own meaning, and culturally competent assessment.
Spiritual Well-Being Scale (SWBS)
The Spiritual Well-Being Scale was developed to measure religious well-being and existential well-being. Its historical importance is substantial, and it has been used across counseling, psychology, health, and religious research. Ellison, 1983
Researchers should be precise about what SWBS scores mean. A spiritual well-being measure is conceptually closer to well-being than a behavioral religiosity measure is. If a study predicts depression, distress, life satisfaction, or quality of life from a scale that already contains closely related meaning or well-being content, correlations may partly reflect construct overlap. That does not make the measure invalid; it changes the question the study can answer.
FACIT-Sp-12: Spiritual Well-Being in Health Research
The FACIT-Sp-12 is a 12-item spiritual well-being measure developed for health-related research. The current FACIT resource describes three domains—Meaning, Peace, and Faith—and a seven-day recall period. It is widely used in oncology and other clinical populations. Researchers should obtain the authorized measure and follow FACIT licensing and translation procedures rather than creating an unofficial translation. FACIT-Sp-12 official measure page Peterman et al., 2002
The instrument’s continuing psychometric literature illustrates why validation cannot be treated as permanent. A 2024 Australian hospital study of 897 patients found that the proposed three-factor 12-item model did not fit that sample optimally without modification, demonstrating that dimensionality may shift across populations and settings. Best et al., 2024
A 2026 paper in people newly diagnosed with advanced cancer examined how respondents interpret the word “spiritual” by testing alternative wording in several Faith items. The modified and original versions showed comparable psychometric characteristics in that sample, and the authors concluded that more research is warranted. The study is a useful reminder that respondents may attach different religious and nonreligious meanings to the same spiritual vocabulary. Bai et al., 2026
How to Choose the Right Instrument
Instrument selection begins with the research question, not with scale popularity. If the study asks whether public and private religious involvement predict a health outcome in a large survey, DUREL may be efficient. If it asks which dimensions of religious/spiritual life are associated with health, BMMRS offers broader domain coverage. If the question is how central religion is to a person’s meaning system, CRS fits more closely. If the focus is ordinary spiritual experience, DSES is more direct. If the study concerns stress response, Brief RCOPE is the relevant family. If the target is religious/spiritual struggle, RSS or RSS-5 is conceptually aligned. If spiritual well-being itself is the outcome, SWBS or FACIT-Sp-12 may be appropriate.
Researchers should also distinguish instruments intended for exposure measurement from instruments intended to describe states, coping, needs, or well-being. A systematic review of spirituality instruments used in clinical research found 35 instruments spanning general spirituality, spiritual well-being, spiritual coping, and spiritual needs, with psychometric evidence often concentrated on content validity and internal consistency rather than the full range of measurement properties. Monod et al., 2011
Reliability Is Necessary, but It Does Not Prove Validity
A high Cronbach’s alpha shows that items are statistically consistent under particular conditions; it does not prove that a scale measures the intended construct, works equally across groups, predicts an external criterion, or is free from conceptual redundancy. The relevant questions include content validity, structural validity, internal consistency, test-retest reliability when stability is expected, convergent and discriminant validity, measurement invariance, and—when change is studied—responsiveness.
Religion/spirituality measures add two special complications. First, constructs may be highly context-dependent. Second, translations may alter theological, experiential, or cultural meaning even when language looks fluent. Guidance focused specifically on religious and spiritual measures emphasizes systematic development, validation, translation, back-translation, and population-specific psychometric testing. Koenig & Al Zaben, 2021
The general theory of reliability and validity belongs to psychometrics. For religion/spirituality research, the crucial domain-specific point is that validation evidence attaches to a particular version, language, population, administration mode, and intended interpretation. A published alpha coefficient from another country or denomination is evidence to consider, not a permanent certificate of validity for every use.
Cross-Cultural and Interreligious Measurement
Religious life is embedded in traditions, communities, languages, histories, rituals, and social norms. A measure developed in one setting can accidentally treat locally common practices as universal indicators of religiosity, or it can privilege individual belief over communal belonging. Theological terms may also have no direct equivalent in another language or may carry a different emotional and doctrinal weight.
Methodological work with Christian, Jewish, and Muslim adolescents has documented practical challenges in adapting religion/spirituality measures across religious groups. More broadly, cross-cultural research should combine careful translation with cognitive interviewing, expert review, pilot testing, and formal tests of factor structure and measurement invariance when group comparisons are planned. Berry et al., 2011
Researchers should avoid assuming that a scale validated among Christians in the United States automatically measures the same construct among Muslims, Jews, Hindus, Buddhists, members of Indigenous traditions, people with syncretic practices, or people who describe themselves as spiritual but not religious. Some instruments have interreligious versions or validated translations; when they do, those versions should be used according to their documentation rather than improvised.
Measurement Invariance Matters When Comparing Groups
Group mean comparisons are most defensible when the instrument functions similarly across the groups being compared. If an item has different meaning or different statistical behavior across languages, traditions, age groups, sexes, or cultural contexts, an observed score difference can partly reflect measurement rather than a true difference in the target construct.
Measurement invariance analysis is therefore especially important in cross-cultural religion/spirituality research. Evidence of invariance in one study strengthens a specific comparison; it does not establish invariance everywhere. The 2026 Brief RCOPE study, for example, supported invariance across biological sex and over treatment time in a residential substance-use-disorder sample, while leaving other cultural and religious comparisons open. Manzler et al., 2026
The Problem of Contaminated Scales and Tautological Associations
One of the most important methodological issues in religion/spirituality and health research is construct contamination. If a purported spirituality predictor contains items about peace, meaning, optimism, positive mood, social support, or other components that closely resemble the mental-health outcome, a positive association can be partly built into the measurement design. The study may then appear to show that spirituality predicts mental health when it is partly correlating mental-health-like content with itself.
Koenig and Carey have emphasized this problem and recommended careful separation of religious/spiritual exposure from health outcomes when causal or predictive claims are the goal. Their 2025 follow-up discusses analytic options for already-collected data, including examining uncontaminated subscales or modeling overlapping psychosocial constructs as mediators rather than treating a contaminated total score as a clean exposure. Koenig & Carey, 2024 Koenig & Carey, 2025
This issue is especially relevant to spiritual well-being instruments. Measures of meaning, peace, and existential well-being can be excellent outcomes in their own right. Problems arise when those same domains are treated as if they were pure measures of religious/spiritual exposure and then correlated with nearly synonymous well-being outcomes.
Scoring: Why There Is Usually No Universal Clinical Cutoff
Most religiosity and spirituality instruments are research measures, not diagnostic tests. Their scores typically indicate degree, frequency, salience, coping pattern, experience, struggle, or well-being within the construct defined by the scale. They usually do not have a universal threshold separating psychologically healthy from unhealthy people.
A high religiosity score is not a diagnosis. A low religiosity score is not a diagnosis. A high religious/spiritual struggle score is not a diagnosis. Positive or negative religious coping scores do not determine whether a person has depression, anxiety, obsessive-compulsive disorder, trauma-related pathology, psychosis, or another clinical disorder. Diagnosis requires clinical criteria, symptom patterns, duration, impairment, differential assessment, cultural context, and professional judgment.
Researchers should use the scoring instructions for the exact authorized version, preserve recommended subscales, report how missing data were handled, and avoid inventing cutoffs from sample medians unless the analysis has a defensible methodological reason. Converting continuous scores into “high” and “low” groups can discard information and create artificial categories.
Religious Belief, Spiritual Experience, and Clinical Assessment
Psychological measurement should not turn religious difference into psychopathology. Religious beliefs, prayer, worship, mystical language, spiritual experiences, and participation in religious communities can be ordinary parts of culturally normative life. Clinical concern arises from patterns of distress, loss of control, functional impairment, danger, or symptoms that require contextual assessment—not from religious content alone.
This distinction becomes especially important when a research scale contains unusual-sounding spiritual language. A self-report response cannot establish a psychotic disorder, dissociative disorder, obsessive-compulsive disorder, or any other diagnosis. Where clinically relevant symptoms are present, assessment should consider the person’s religious and cultural context and the norms of their community.
Common Research Design Errors
Several recurring errors weaken religion/spirituality studies. The first is selecting a familiar scale before defining the construct. The second is reporting only internal consistency and calling the instrument “validated.” The third is using a translated scale without documenting cultural adaptation. The fourth is combining conceptually different subscales into a total score that the instrument was not designed to support. The fifth is comparing groups without testing whether the measure functions similarly across them.
Other errors include using spiritual well-being as a predictor of nearly identical well-being outcomes, treating attendance as a complete measure of religious life, assuming the absence of affiliation means the absence of spirituality, and interpreting a score difference as a causal effect of religion. Cross-sectional associations cannot by themselves establish direction of causality.
A Practical Workflow for Selecting a Religiosity or Spirituality Measure
Begin by writing a one-sentence construct definition that does not name a scale. Specify whether the target is religious participation, private practice, centrality, experience, coping, struggle, identity, support, spiritual well-being, or another domain. Then define the population, tradition or traditions, language, age range, setting, and intended inference.
Next, examine candidate instruments at the item and subscale level. Read the development paper and the most relevant validation studies. Check whether the factor structure has been reproduced, whether the scale has been tested in the target language and cultural setting, whether measurement invariance evidence exists for planned comparisons, and whether any items overlap with the primary outcome.
For translations, use an authorized version when one exists. Translation should preserve construct meaning rather than merely word-for-word language. Research on religious/spiritual measures specifically recommends structured translation and psychometric validation procedures. Koenig & Al Zaben, 2021
Finally, preregister the intended scoring and analysis when possible. State which subscales are primary, how missing responses will be handled, whether scores will remain continuous, and how multiple comparisons will be controlled. In the published paper, report the exact version, language, administration mode, scoring rule, reliability estimates in the current sample, and the evidence supporting the interpretation you make.
Instrument Selection by Research Question
For large epidemiological studies of religious involvement, DUREL offers economy and clear subdomains. For multidimensional health research, BMMRS provides a broader map. For the centrality of religion in personality, CRS is the more direct conceptual fit. For ordinary spiritual experiences, DSES is designed around daily experience. For coping with stress, Brief RCOPE directly measures religious coping strategies. For religious and spiritual struggles, the 26-item RSS provides richer domain information and the RSS-5 offers a low-burden short form. For spiritual well-being as an outcome, SWBS and FACIT-Sp-12 are widely used options, with careful attention to construct overlap when mental health or quality of life is also an outcome.
There is no scientifically defensible rule that the longest instrument is always best or that the shortest is always more practical. The best instrument is the one whose construct, validation evidence, burden, cultural fit, and scoring structure match the actual study.
Limitations of the Evidence Base
The religion/spirituality measurement literature is large but uneven. Many scales have been used far more often than they have been independently revalidated. Older instruments may have extensive accumulated use while reflecting assumptions from the cultural and religious settings in which they were developed. Newer short forms can reduce burden but may sacrifice domain resolution.
Systematic reviews also show that psychometric coverage is often incomplete. For example, the 2011 clinical spirituality review found many instruments but comparatively limited evidence beyond content validity and internal consistency. Reviews of translated measures have similarly reported that some instruments lack comprehensive assessment of test-retest reliability, discriminant validity, or other properties. Monod et al., 2011
The field also faces definitional heterogeneity. Studies can use the same word—“spirituality”—for transcendence, religious commitment, meaning, peace, connectedness, or combinations of these. This makes meta-analysis and causal interpretation difficult unless instruments are classified by what their items actually measure. Jeserich et al., 2023
Frequently Asked Questions
What is the best scale for measuring religiosity?
There is no single best scale for every study. DUREL is efficient for religious involvement, CRS measures centrality, and BMMRS covers multiple domains. The best choice follows the construct and population.
Is DUREL a measure of spirituality?
DUREL primarily measures religious involvement through organizational activity, non-organizational activity, and intrinsic religiosity. It is not a comprehensive spirituality measure. Koenig & Büssing, 2010
What does the Brief RCOPE measure?
It measures positive and negative religious coping strategies used in relation to major stressors. It does not measure overall religiosity, spiritual well-being, or psychiatric diagnosis. Pargament, Feuille, & Burdzy, 2011
Can the RSS or RSS-5 diagnose a mental disorder?
No. They measure religious and spiritual struggles. Scores can identify research-relevant variation in struggle, but diagnosis requires a broader clinical assessment. Exline et al., 2014 Salcone et al., 2025
Can the same scale be used across different religions?
Sometimes, but cross-religious use requires evidence that the wording and construct are meaningful across the traditions being compared. Instruments such as the CRS include interreligious variants, while other scales may require validated adaptations. A fluent translation alone does not establish equivalence. Huber & Huber, 2012 Berry et al., 2011
Is a high Cronbach’s alpha enough to show that a measure is valid?
No. Internal consistency is one measurement property. Researchers also need evidence appropriate to the intended interpretation, including content and structural validity, discriminant and convergent validity, and—when groups or time points are compared—measurement invariance.
Why can spiritual well-being scales be problematic in mental health research?
They are not inherently problematic. The issue is overlap. If a spiritual well-being scale contains meaning, peace, positive emotion, or social-health content and is then used to predict closely related mental-health outcomes, part of the association may be tautological. Koenig & Carey, 2024
Should researchers reproduce questionnaire items in an article or survey appendix?
Only when the instrument’s permissions allow it. Many measures are copyrighted, licensed, or have authorized translation procedures. Researchers should obtain the official version and comply with the instrument owner’s conditions. FACIT-Sp-12, for example, has explicit registration, licensing, and translation requirements.
